Transplante dentário autólogo: revisão integrativa / Dental autologous transplantation: an integrative literaturereview / Trasplante dental autólogo: una revisión integradora de la literatura

Introdução:O transplante autólogo dentário é uma técnica cirúrgica na qual há a transposição de um dente para uma nova área receptora, no mesmo paciente. É viável para o tratamento de ausências e impactações dentárias. O método apresenta benefícios como manutenção de periodonto vital, volume ósseo alveolar e papila dentária, possibilidade de movimentação dentária por forças ortodônticas ou fisiológicas e estética favorável.Objetivo:Promover uma revisão de literatura sobre o transplante dentário autólogo, visando relatar as principais indicações, benefícios e contraindicações da técnica, além de descrever o protocolo cirúrgico e os fatores que influenciam no sucesso, de modo a orientar o manejo clínico.Metodologia:Para esse fim, as bases de dados analisadas foram PUBMED, LILACS e SCIELO, sendo obtidos artigos de Revisão Sistemática e Metanálises dos anos de 2018 a 2023.Resultados:O autotransplante apresenta taxas de sobrevida entre 93% e 100% e taxas de sucesso entre 89,4% e 96,6%, o que depende dos fatores relacionados ao paciente, ao dente doador, à área receptora e à técnica cirúrgica.Dentes anteriores e com ápice aberto apresentam melhores taxas de sobrevivência e sucesso em relação aos dentes posteriores e de ápice fechado, todavia não há comprovação que os demais pontos realmente influenciam diretamente no método. Conclusões:Com isso, podemos compreender que o estabelecimento de protocolos pré,trans e pós-operatório, além de esclarecimento de todos os fatores que influenciam na técnica, devem ser foco de estudos dos Cirurgiões-Dentistas, trazendo benefícios consideráveisparao manejo cirúrgico e saúde desses pacientes (AU).

Introduction:Autologous dental transplantation is a surgical technique in which there is the transposition of a tooth to a new recipient area within the same patient. It is a viable option for treating dental absenteeism and impactions. The method offers benefits such as the maintenance of vital periodontium, alveolar bone volume, and dental papilla, the possibility of dental movement through orthodontic or physiological forces, and favorable aesthetics.Objective:To promote a literature review on autologous dental transplantation, aiming to report the main indications, benefits, and contraindications of the technique, in addition to describe the surgical protocol and factors influencing success, providing guidance for clinical management.Methodology:For this purpose, the analyzed databases included PUBMED, LILACS, and SCIELO, obtaining Systematic Review and Meta-Analysesarticles from the years 2018 to 2023.Results:Autotransplantation presents survival rates between 93% and 100% and success rates between 89.4% and 96.6%, depending on factors related to the patient, the donor tooth, the recipient area, and the surgical technique. Anterior teeth with open apices present better survival and success rates compared to posterior teeth with closed apices, however, there is no conclusive evidence that other factors directly influence the method.Conclusions:Therefore, we can understand that the establishment of preoperative, intraoperative, and postoperative protocols, along with clarification of all factors influencing the technique, should be the focus of studies for Dental Surgeons, bringing significant benefits to these individuals' health (AU).

Retinoblastoma in the Southern Philippines: Clinical outcomes of retinoblastoma patients in a Davao Tertiary Hospital

Background@#Retinoblastoma is the most common intraocular cancer in childhood in the Philippines. Most data though on demographics, clinical profile, treatment options, and outcomes in the country are from the National Capital Region. @*Objectives@#This study aimed to describe the demographics, clinical profile, treatment done, and outcomes of retinoblastoma patients seen in a public tertiary referral center in Davao from 2011-2020 to make available literature more representative of the status of retinoblastoma in the Philippines. @*Methods@#An analytical cross-sectional study was conducted using the records of retinoblastoma patients seen in a tertiary government hospital located in Davao Region from January 2011 to December 2020. @*Results@#There were 157 patients included in the analysis. Seventy-three (46%) were female with 44% coming from the Davao Region. One hundred seven (69%) patients had unilateral disease. Median age at initial consultation for patients with unilateral disease was significantly older than those with bilateral disease (p<0.003). Tumors were extraocular in 82 (40%) eyes. In the intraocular group, 36% of the eyes belonged to International Classification of Retinoblastoma (ICRB) Groups D and E. Enucleation was the most commonly performed treatment. Survival rate was 28%. This is the first report to provide epidemiologic and clinical data on retinoblastoma in the literature, including survival data, from Mindanao. Advanced stages and extraocular cases of retinoblastoma remain high. Delay of consultation contributed to the prognosis and clinical outcome of the disease.@*@#Conclusion. Advanced stages and extraocular cases of retinoblastoma remain significantly high in the country, even in Mindanao.

Significados atribuídos por mulheres com câncer de mama ao grupo de apoio / Meanings attributed by women with breast cancer to a support group / Significados atribuidos por las mujeres con cáncer de mama al grupo de apoyo

A sobrevivência ao câncer de mama é um problema de saúde pública que demanda serviços especializados com foco na reabilitação psicossocial. Entre as necessidades identificadas nesse contexto está o incentivo à adoção de estratégias de promoção de autocuidados pelas mulheres. Uma das estratégias adotadas consiste no grupo de apoio psicológico, que auxilia as pacientes a enfrentar a longa jornada do tratamento. Assim, o objetivo deste estudo é compreender os significados produzidos por mulheres com câncer de mama sobre sua participação em um grupo de apoio. Trata-se de um estudo qualitativo, descritivo e exploratório realizado com dez mulheres com câncer de mama usuárias de um serviço de reabilitação para mastectomizadas. Como referencial metodológico foi utilizada a Teoria Fundamentada nos Dados. A coleta de dados foi realizada por meio de entrevista aberta em profundidade e os conteúdos foram transcritos e codificados. A análise indutiva e o método de comparação constante foram aplicados nos processos de codificação aberta, axial e seletiva, que permitiram identificar três categorias nucleares: percepção das atividades realizadas no grupo, identificação de benefícios e barreiras do convívio no grupo e transformações decorrentes da participação. As participantes significaram sua presença no grupo como fonte de acolhimento, apoio, desenvolvimento de recursos pessoais e amizades, contribuindo para promover sua qualidade de sobrevida. Além dos potenciais benefícios, também foram identificadas barreiras que podem dificultar a adesão e continuidade da participação no grupo, o que sugere a necessidade de incorporar no cuidado um olhar para as dimensões subjetivas da saúde da mulher.(AU)

Surviving breast cancer is a public health problem and depends on services focused on psychosocial rehabilitation. Healthcare providers must encourage women to adopt strategies to promote their self-care. The psychological support group is a resource that helps women to face the long journey of treatment. This study aimed to understand the meanings women with breast cancer produced about their participation in a support group. This exploratory cross-sectional study was carried out with 10 women with breast cancer who use a rehabilitation service for mastectomized patients. Grounded Theory was used as a methodological reference. An open in-depth interview was applied for data collection. The contents were transcribed and coded. Inductive analysis and the constant comparison method were applied in the open, axial, and selective coding processes, which enabled the identification of three core categories: perception of the activities carried out in the group, identification of benefits and barriers of living in the group, and transformations resulting from participation. Participants denote their involvement with the group as a source of shelter, support, development of personal resources and friendships that helps promoting quality of life. Besides these potential benefits, participants also evinced barriers that can hinder adherence and continuity of participation in the group, suggesting the importance of incorporating a look at the subjective dimensions of women's health into care.(AU)

Las mujeres denotan su participación en el grupo como una fuente de acogida, apoyo, desarrollo de recursos personales y amistades, que ayuda a promover la calidad de vida. Además de los beneficios potenciales, también se identificaron barreras que pueden dificultar la adherencia y continuidad de la participación en el grupo, lo que sugiere la necesidad de incorporar en la atención una mirada centrada en las dimensiones subjetivas de la salud de las mujeres.(AU)

Sobrevida del cáncer glótico en estadio inicial en 4 centros hospitalarios de Uruguay / Survival of glottic cancer in the initial stage in 4 hospital centers in Uruguay / Sobrevivência de câncer glótico em estágio inicial em 4 hospitais uruguaios

Introducción: El cáncer de laringe es el tumor maligno de mayor prevalencia en la Otorrinolaringología. La topografía glótica es la más frecuente en Uruguay y suele detectarse en estadios tempranos dada la manifestación precoz y sostenida de disfonía. El objetivo de este estudio es describir la sobrevida libre de enfermedad (SLE) y la sobrevida global (SG) de los pacientes con cáncer de laringe glótico en estadio T1N0M0 en 4 instituciones de Montevideo. Metodología: Se analizó de forma retrospectiva la SG y SLE de 55 pacientes diagnosticados con cáncer de glotis T1 entre los años 2009 y 2019. Para el cálculo de la sobrevida se utilizó el método de Kaplan-Meier. Se estudió además el efecto de variables pronósticas de interés sobre la SG mediante análisis univariado y multivariado. Resultados: En la muestra analizada la SG de los pacientes con cáncer glótico T1N0M0 fue como media de 7.706 años (IC 95% 6.63 - 8.78). A los 5 años, la SG fue de 77.5% (± 7%) y de 62% (± 9.8%) a los 10 años. La SLE para todos los pacientes correspondió al 74.6% (± 7.5%) y 63.1% (± 9.8%), a 5 y 10 años respectivamente. No se alcanzaron las medianas de SG ni de SLE para los grupos. Conclusiones: Los valores de SG y SLE medios obtenidos en nuestro medio son comparables a los valores reportados en la bibliografía internacional. No se alcanzó la mediana de SG ni de SLE, por lo que se puede afirmar que ésta enfermedad tiene, cuando se realiza el tratamiento adecuado, un buen pronóstico vital a los 10 años. Se requiere un seguimiento más largo para determinar las medianas de SG y SLE de los grupos en estudio.

Introduction: Laryngeal cancer is the most prevalent malignant tumor in Otorhinolaryngology. Glottic topography is the most frequent in Uruguay and is usually detected in early stages given the early and sustained manifestation of dysphonia. The objective of this study is to analyze disease-free survival (DFS) and overall survival (OS) of patients with stage T1N0M0 glottic laryngeal cancer at 4 institutions in Montevideo. Methodology: The mean OS and DFS of 55 patients diagnosed with T1 glottic cancer between 2009 and 2019 were retrospectively analyzed. Kaplan-Meier method was used to calculate survival. The prognostic effect of certain variables of interest on OS was also studied using univariate and multivariate analysis. Results: In this study, mean odds survival (OS) for T1N0M0 glottic cancer was 7.706 years (CI 95% 6.63 - 8.78). At 5 years, OS was 77.5% (± 7%) and at 10 years was 62% (± 9.8%). Disease free survival (DFS) was 74.6% ± (7.5%) at 5 years and 63.1% (± 9.8%), at 10 years. Median OS and DFS for the groups were not reached. Conclusions: OS and DFS in our medium is comparable to that reported in the international literature. The median OS and DFS were not reached, so it can be stated that this disease has, when appropriate treatment is performed, a good vital prognosis at 10 years. Longer follow-up is required to determine the median OS and DFS of the study groups.

Introdução: O câncer de laringe é o tumor maligno mais prevalente na Otorrinolaringologia. A topografia glótica é a mais frequente no Uruguai e geralmente é detectada em estágios iniciais devido à manifestação precoce e sustentada da disfonia. O objetivo deste estudo é analisar a sobrevida livre de doença (DFS) e a sobrevida global (OS) de pacientes com câncer de laringe glótico estágio T1N0M0 em 4 instituições em Montevidéu. Metodologia: Foram analisados retrospectivamente o OS e DFS de 55 pacientes diagnosticados com câncer glótico T1 entre 2009 e 2019. O método de Kaplan-Meier foi usado para calcular a sobrevida. Resultados: Na amostra, a sobrevida global (OS) do câncer glótico T1N0M0 foi em média de 7.706 anos (IC 95% 6,63 - 8,78). Aos 5 anos, a OS foi de 77,5% (± 7%) e 62% (± 9,8%) aos 10 anos. A DFS para todos os pacientes correspondeu a 74,6% (± 7,5%) e 63,1% (± 9,8%), aos 5 e 10 anos, respectivamente. As medianas de OS e DFS para os grupos não foram alcançadas. Conclusões: OS e DFS em nosso ambiente é comparável ao relatado na literatura internacional. As medianas de SG e SLD não foram alcançadas, pelo que se pode afirmar que esta doença apresenta, quando realizado tratamento adequado, um bom prognóstico vital aos 10 anos. É necessário um acompanhamento mais longo para determinar a mediana da SG e da SLD dos grupos de estudo.

Características de los niños y adolescentes con enfermedades pulmonares crónicas derivados para evaluación por equipo de trasplante pulmonar de Uruguay en el período 2003 - 2023 / Characteristics of children and adolescents with chronic lung diseases referred for assessment by the Uruguayan lung transplant team in 2003 - 2023 / Características de crianças e adolescentes com doenças pulmonares crônicas referidas para avaliação pela equipe uruguaia de transplante pulmonar no período 2003 - 2023

Introducción: el trasplante pulmonar se ha consolidado en los últimos años como una opción terapéutica para niños y adolescentes con enfermedad pulmonar grave en la que han fracasado otros tratamientos. Este procedimiento otorga una buena calidad de vida y una supervivencia prolongada, similar a la del trasplante realizado en pacientes adultos. La indicación general para el trasplante pulmonar es la insuficiencia respiratoria progresiva, y potencialmente letal, debida a una enfermedad pulmonar parenquimatosa o vascular. La selección de candidatos a trasplante es compleja, requiriendo condiciones médicas y socioambientales específicas. Objetivos: analizar las características clínicas de los pacientes pediátricos con enfermedades pulmonares crónicas derivados para evaluación por el equipo de trasplante pulmonar de Uruguay. Analizar las características clínicas y sobrevida de los pacientes trasplantados pulmonares pediátricos uruguayos. Material y métodos: estudio descriptivo y retrospectivo de todos los pacientes menores de 19 años derivados al equipo de trasplante pulmonar entre 2003 y 2023. Datos obtenidos de la base del programa y mediante revisión de historias clínicas. Resultados: se incluyeron 30 pacientes (15 de sexo masculino). La media de edad de los pacientes derivados fue de 13,4 ± 3,6 años. Las etiologías de los pacientes derivados fueron 17/30 (56,6%) fibrosis quística, 4/30 (13,3%) bronquiolitis obliterante postrasplante de médula ósea, 4/30 (13,3%) hipertensión pulmonar, 3/30 (10%) bronquiolitis obliterante posinfecciosa y 2/30 (6,6%) enfermedad pulmonar intersticial difusa. Ingresaron en lista de trasplante 14 pacientes, de los cuales 9 se trasplantaron, 1 se mantiene en lista de espera y 4 fallecieron a la espera del trasplante. Del resto de los pacientes derivados para evaluación: 7 pacientes se encuentran aún en evaluación. Fueron excluidos por razones psicosociales o causas médicas 2 pacientes. Dos pacientes tuvieron pérdida de seguimiento y otros 5 fallecieron durante la evaluación. Las etiologías de los pacientes trasplantados pediátricos fueron fibrosis quística (3/9), bronquiolitis obliterante postrasplante de médula ósea (3/9) e hipertensión pulmonar (3/9). De los pacientes trasplantados, 5 fallecieron (2 en el posoperatorio y 3 fallecieron por sepsis entre 1-2 años postrasplante). Los restantes pacientes están en seguimiento postrasplante hace un mes, 2, 7 y 9 años. No se han encontrado diferencias estadísticamente significativas en la sobrevida condicional cuando se compararon pacientes adultos y pediátricos. Conclusiones: los resultados en los pacientes trasplantados en cuanto a características y causas de mortalidad son comparables con los reportados internacionalmente. La mortalidad postrasplante fue algo mayor que en otros estudios, pero creemos que existe sesgo por el bajo número de pacientes. Dados los resultados mencionados, planteamos que el trasplante sigue siendo una alternativa terapéutica válida en nuestro medio. Los desafíos de este tratamiento incluyen la disponibilidad limitada de órganos de donantes adecuados, la toxicidad de los medicamentos inmunosupresores necesarios para prevenir el rechazo, la prevención y el tratamiento de la bronquiolitis obliterante, así como maximizar el crecimiento, el desarrollo y la calidad de vida de los receptores.

Summary: Introduction: lung transplantation has been recently consolidated as a therapeutic option for children and adolescents with severe lung disease when other treatments have failed. This procedure provides a good quality of life and additional survival, similar to that of transplantation in adult patients. The general indication for lung transplantation is progressive, potentially fatal respiratory failure due to parenchymal or vascular lung disease. The selection of transplant candidates is complex, requiring specific medical and socio-environmental conditions. Objectives: to analyze the clinical characteristics of pediatric patients with chronic lung diseases referred for evaluation by the Uruguayan lung transplant team. To analyze the clinical characteristics and survival of Uruguayan pediatric lung transplant patients. Material and methods: descriptive and retrospective study of all patients under 19 years of age referred to the lung transplant team between 2003 and 2023. The data was obtained from the program's database and through medical records' review. Results: 30 patients were included (15 male). The mean age of the referred patients was 13.4 ± 3.6 years. Etiologies were 17/30 (56.6%) cystic fibrosis, 4/30 (13.3%) bronchiolitis obliterans post-bone marrow transplant, 4/30 (13.3%) pulmonary hypertension, 3 /30 (10%) post-infectious bronchiolitis obliterans, and 2/30 (6.6%) diffuse interstitial lung disease. 14 patients were placed on the transplant list, of which 9 were transplanted, 1 remains on the waiting list and 4 died while waiting for the transplant. Of the rest of the patients referred for evaluation: 7 patients are still under evaluation. 2 patients were excluded for psychosocial reasons or medical reasons. 2 patients could not be followed-up and other 5 died during the evaluation. The etiologies of the pediatric transplant patients were cystic fibrosis (3/9), post-bone marrow transplant bronchiolitis obliterans (3/9), and pulmonary hypertension (3/9). Of the transplanted patients, 5 died (two in the post-operative period, and three died from sepsis between 1-2 years post-transplant). The remaining patients are in post-transplant follow-up for 1 month, 2, 7 and 9 years. No statistically significant differences in conditional survival were found when comparing adult and pediatric patients. Conclusions: results in transplanted patients in terms of characteristics and causes of mortality are comparable with those reported internationally. Post-transplant mortality was somewhat higher than in other studies, but we believe that there is bias due to the low number of patients. Given the results above, we propose that transplantation continues to be a valid therapeutic alternative in our country. The challenges of this treatment include the limited availability of suitable donor organs, the toxicity of immunosuppressive medications necessary to prevent rejection, prevention and treatment of bronchiolitis obliterans, as well as maximizing the growth, development and quality of life of the receivers.

Material e métodos: estudo descritivo e retrospectivo de todos os pacientes menores de 19 anos encaminhados à equipe de transplante pulmonar entre 2003 e 2023. Os dados foram obtidos no banco de dados do programa e por meio de revisão de prontuários. Foram incluídos 30 pacientes (15 do sexo masculino). A média de idade dos pacientes encaminhados foi de 13,4 ± 3,6 anos. As etiologias dos pacientes encaminhados foram 17/30 (56,6%) fibrose cística, 4/30 (13,3%) bronquiolite obliterante pós-transplante de medula óssea, 4/30 (13,3%) hipertensão pulmonar, 3/30 (10%) pós -bronquiolite obliterante infecciosa e 2/30 (6,6%) doença pulmonar intersticial difusa. Foram colocados na lista de transplante 14 pacientes, dos quais 9 foram transplantados, 1 permanece em lista de espera e 4 faleceram enquanto aguardavam o transplante. Do restante dos pacientes encaminhados para avaliação: 7 pacientes ainda estão em avaliação, 2 pacientes foram excluídos por motivos psicossociais ou médicos. 2 pacientes foram perdidos no acompanhamento e outros 5 faleceram durante a avaliação. As etiologias dos pacientes transplantados pediátricos foram fibrose cística (3/9), bronquiolite obliterante pós-transplante de medula óssea (3/9) e hipertensão pulmonar (3/9). Dos pacientes transplantados, 5 faleceram (dois no pós-operatório e três por sepse entre 1-2 anos pós-transplante). Os demais pacientes estão em acompanhamento pós-transplante por 1 mês, 2, 7 e 9 anos. Não foram encontradas diferenças estatisticamente significativas na sobrevida condicional quando comparamos pacientes adultos e pediátricos. Conclusões: os resultados em pacientes transplantados em termos de características e causas de mortalidade são comparáveis aos relatados internacionalmente. A mortalidade pós-transplante foi um pouco maior do que em outros estudos, mas acreditamos que exista viés devido ao baixo número de pacientes. Diante dos resultados acima mencionados, propomos que o transplante continue sendo uma alternativa terapêutica válida em nosso meio. Os desafios deste tratamento incluem a disponibilidade limitada de órgãos de doadores adequados, a toxicidade dos medicamentos imunossupressores necessários para prevenir a rejeição, prevenção e tratamento da bronquiolite obliterante, bem como maximizar o crescimento, desenvolvimento e qualidade de vida dos receptores.

Osteosarcoma como patología GES. Experiencia de 7 años en Centro de Referencia Nacional / Osteosarcoma as a GES-Listed Pathology: 7-Year Experience at a National Reference Center

INTRODUCCIÓN: El osteosarcoma (OS) es el tumor óseo primario maligno más frecuente. En 2014 se incorporó en Chile dentro del plan de garantías explícitas en salud (GES), ley que garantiza el tratamiento desde la sospecha hasta su tratamiento y rehabilitación. OBJETIVOS: Describir las características de la población mayor de 15 años, con diagnóstico histopatológico de OS, definir su sobrevida, complicaciones e identificar variables que afectan estos resultados. MATERIAL Y MÉTODOS: Estudio retrospectivo, se incluyó a todos los pacientes con diagnóstico de OS, con confirmación histológica, desde 2014 a 2020. Datos demográficos, sitio anatómico, hallazgos histopatológicos, estadio de ingreso, presencia de metástasis, tratamiento, complicaciones y sobrevida fueron registrados. Se realizó un estudio multivariante para determinar factores pronósticos. RESULTADOS: 133 pacientes fueron incluidos. 58,8% hombres, la edad promedio fue 31 años y la localización más frecuente fue fémur distal (34,9%). El 56,4% de los pacientes ingresó en estadio Enneking IIB, 36,4% presentó metástasis al ingreso. Un 14,3% presentó complicaciones, siendo la más frecuente la infección periprotésica (6 casos). El 16% evolucionó con recidiva local. El modelo multivariante mostró que la edad y presencia de metástasis al ingreso constituyen variables pronósticas independientes, con un cociente de riesgo de 1,017 para edad (p = 0,016) y de 3,13 para presencia de metástasis (p = 0,0000). En el análisis de subgrupos, los pacientes sin metástasis al diagnóstico presentaron sobrevida a 5 años de 54% versus 11% para el grupo con metástasis; al ajustar por edad, la sobrevida a 5 años para el grupo sin metástasis y con metástasis fue de 73% y 22% respectivamente. CONCLUSIÓN: Este es el primer estudio de descripción demográfica de pacientes con OS que se realiza en nuestro país. Los resultados son similares a lo reportado por la literatura internacional, destacando en nuestra serie la edad de presentación y presencia de metástasis al ingreso como factores que afectan el pronóstico de una manera significativa. Al ajustar por edad, los porcentajes de sobrevida son equiparables con lo reportado en otros centros internacionales especializados en sarcomas.

BACKGROUND: Osteosarcoma (OS) is the most frequent malignant primary bone tumor. The explicit health guarantee (GES) plan in Chile, a law that guarantees diagnosis, treatment, and rehabilitation, incorporated OS in 2014. OBJETIVES: To describe the characteristics of the population over 15 years, with a histopathological diagnosis of OS, to define survival rate and complications, and to identify variables that affect these outcomes. METHODS: A retrospective study from 2014 to 2020, including all patients affiliated with the public health system diagnosed with OS, with histological confirmation. From clinical records, we extracted demographic data, anatomical OS location, histopathological findings, admission stage, presence of metastases, treatment, complications, and survival. We determined prognostic factors by multivariate analysis. Results: 133 patients, 58.8% men, the average age was 31 years, and the most frequent location was the distal femur (34.9%). 56.4% of the patients were admitted in Enneking stage IIB, and 36.4% presented metastasis at admission. 14.3% presented complications, the most frequent periprosthetic infection (6 cases). 16% of patients evolved with local recurrence. The multivariate model showed that age and metastases at admission constitute independent prognostic variables, with a hazard ratio of 1.017 for age (p = 0.016) and 3.13 for metastases (p = 0.0000). In the subgroup analysis, patients without metastases at diagnosis had a 5-year survival of 54% versus 11% for the group with metastases. Adjusting for age, the 5-year survival for the non-metastatic and metastatic groups was 73% and 22%, respectively. CONCLUSION: This is our country's first demographic description study of patients with OS. In our series, the age of presentation and the presence of metastases at admission were factors that significantly affect prognosis. When adjusting for age, the survival percentages are comparable to those reported in other international centers specialized in sarcomas.

Persistent increase and improved survival of stage I lung cancer based on a large-scale real-world sample of 26,226 cases / 中华医学杂志(英文版)

BACKGROUND@#Lung cancer prevails and induces high mortality around the world. This study provided real-world information on the evolution of clinicopathological profiles and survival outcomes of lung cancer, and provided survival information within stage I subtypes.@*METHODS@#Patients pathologically confirmed with lung cancer between January 2009 and December 2018 were identified with complete clinicopathological information, molecular testing results, and follow-up data. Shifts in clinical characteristics were evaluated using χ2 tests. Overall survival (OS) was calculated through the Kaplan-Meier method.@*RESULTS@#A total of 26,226 eligible lung cancer patients were included, among whom 62.55% were male and 52.89% were smokers. Non-smokers and elderly patients took increasingly larger proportions in the whole patient population. The proportion of adenocarcinoma increased from 51.63% to 71.80%, while that of squamous carcinoma decreased from 28.43% to 17.60%. Gene mutations including EGFR (52.14%), KRAS (12.14%), and ALK (8.12%) were observed. Female, younger, non-smoking, adenocarcinoma patients and those with mutated EGFR had better survival prognoses. Importantly, this study validated that early detection of early-stage lung cancer patients had contributed to pronounced survival benefits during the decade. Patients with stage I lung cancer, accounted for an increasingly considerable proportion, increasing from 15.28% to 40.25%, coinciding with the surgery rate increasing from 38.14% to 54.25%. Overall, period survival analyses found that 42.69% of patients survived 5 years, and stage I patients had a 5-year OS of 84.20%. Compared with that in 2009-2013, the prognosis of stage I patients in 2014-2018 was dramatically better, with 5-year OS increasing from 73.26% to 87.68%. Regarding the specific survival benefits among stage I patients, the 5-year survival rates were 95.28%, 93.25%, 82.08%, and 74.50% for stage IA1, IA2, IA3, and IB, respectively, far more promising than previous reports.@*CONCLUSIONS@#Crucial clinical and pathological changes have been observed in the past decade. Notably, the increased incidence of stage I lung cancer coincided with an improved prognosis, indicating actual benefits of early detection and management of lung cancer.

China Anti-Cancer Association (CACA) guidelines for holistic integrative management of cancer-peritoneal tumours from gastrointestinal tract / 中华胃肠外科杂志

Peritoneal tumours have a large population and a poor prognosis with limited therapeutic options available, and are common originated from gastric, colorectal, appendix and other cancers. Traditionally, peritoneal tumours have long been considered to be a terminal condition with a median survival of 3-6 months, and the palliative symptomatic treatment is recommended. Recently, the multimodal therapeutic strategy of cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) has resulted in more effective on the prevention and treatment of peritoneal metastasis, which can significantly improve the survival and quality of life. Under the guidance of the China Anti-Cancer Association (CACA), the "CACA Guidelines for Holistic Integrative Management of Cancer-Peritoneal Tumours" was jointly completed by experts in related fields organized by the Chinese Society of Peritoneal Oncology.

Advances in post-operative prognostic models for hepatocellular carcinoma / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Hepatocellular carcinoma (HCC) is one of the most common malignancies and a leading cause of cancer-related death worldwide. Surgery remains the primary and most successful therapy option for the treatment of early- and mid-stage HCCs, but the high heterogeneity of HCC renders prognostic prediction challenging. The construction of relevant prognostic models helps to stratify the prognosis of surgically treated patients and guide personalized clinical decision-making, thereby improving patient survival rates. Currently, the prognostic assessment of HCC is based on several commonly used staging systems, such as Tumor-Node-Metastasis (TNM), Cancer of the Liver Italian Program (CLIP), and Barcelona Clinic Liver Cancer (BCLC). Given the insufficiency of these staging systems and the aim to improve the accuracy of prognostic prediction, researchers have incorporated further prognostic factors, such as microvascular infiltration, and proposed some new prognostic models for HCC. To provide insights into the prospects of clinical oncology research, this review describes the commonly used HCC staging systems and new models proposed in recent years.

Clinicopathological features and prognostic factors of patients with lung metastasis of stage Ⅰa~Ⅲb cervical cancer / 中华肿瘤杂志

Objective: To investigate the clinicopathological features and prognostic factors of lung metastasis in patients with cervical cancer after treatment. Methods: The clinicopathological data of 191 patients with lung metastasis of stage Ⅰa-Ⅲb cervical cancer (FIGO 2009 stage) treated in Sichuan Cancer Hospital from January 2007 to December 2020 were analyzed retrospectively. Kaplan Meier method and Log rank test were used for survival analysis, and Cox regression model was used for prognostic factors analysis. Results: Among 191 patients with lung metastasis of cervical cancer, pulmonary metastasis was found in 134 patients (70.2%) during follow-up examination, and 57 patients (29.8%) had clinical symptoms (cough, chest pain, shortness of breath, hemoptysis, and fever). The time from the initial treatment of cervical cancer to the discovery of lung metastasis was 1-144 months in the whole group, with a median time of 19 months. Univariate analysis of the prognosis of lung metastasis after treatment of cervical cancer showed that the diameter of cervical tumor, lymph node metastasis, positive surgical margin, disease-free interval after treatment of cervical cancer, whether it is accompanied by other metastasis, the number, location and maximum diameter of lung metastasis, and the treatment method after lung metastasis are related to the prognosis of patients with lung metastasis of cervical cancer. Multivariate analysis showed that the number of lung metastases and other site metastases in addition to lung metastases were independent factors affecting the prognosis of patients with lung metastases of cervical cancer (P<0.05). Conclusions: For patients with cervical cancer, attention should be paid to chest CT examination during follow-up to guard against the possibility of lung metastasis after treatment. Besides lung metastasis, other site metastasis and the number of lung metastasis are independent factors affecting the prognosis of patients with lung metastasis of cervical cancer. For patients with lung metastasis after treatment of cervical cancer, surgical treatment is an effective treatment. It is necessary to strictly grasp the surgical indications, and some patients can achieve long-term survival. For patients with lung metastasis of cervical cancer who are not suitable for resection of lung metastasis, the remedial treatment of chemotherapy with or without radiotherapy is still a recommended choice.

Focusing on timing selection and whole-course management of liver transplantation treatment for patients with acute-on-chronic liver failure / 中华肝脏病杂志

Acute-on-chronic liver failure (ACLF) is a clinical syndrome of acute decompensation accompanied by organ failure that occurs on the basis of chronic liver disease and has a high short-term mortality rate. Currently, there are still differences in relation to the definition of ACLF; thus, baseline characteristics and dynamic changes are important bases for clinical decision-making in patients with liver transplantation and others. The basic strategies for treating ACLF currently include internal medicine treatment, artificial liver support systems, and liver transplantation. Multidisciplinary active collaborative management throughout the whole course is of great significance for further improving the survival rate in patients with ACLF.

Long-term trend analysis of liver cancer survival rate in Qidong region, Jiangsu Province, 1972-2019 / 中华肝脏病杂志

Objective: To analyze the incidence and survival rate of liver cancer cases in the entire population in the Qidong region from 1972 to 2019, so as to provide a basis for prognosis evaluation, prevention, and treatment. Methods: The observed survival rate (OSR) and relative survival rate (RSR) of 34 805 cases of liver cancer in the entire Qidong region population from 1972 to 2019 were calculated using Hakulinen's method with SURV3.01 software. Hakulinen's likelihood ratio test was used for statistical analysis. Age-standardized relative survival (ARS) was calculated using the International Cancer Survival Standard. The Joinpoint regression analysis was performed with Joinpoint 4.7.0.0 software to calculate the average annual percentage change (AAPC) of the liver cancer survival rate. Results: 1-ASR increased from 13.80% in 1972-1977 to 50.20% in 2014-2019, while 5-ASR increased from 1.27% in 1972-1977 to 27.64% in 2014-2019. The upward trend of RSR over eight periods was statistically significant (χ (2) = 3045.29, P < 0.001). Among them, male 5-ASR was 0.90%, 1.80%, 2.33%, 4.92%, 5.43%, 7.05%, 10.78%, and 27.78%, and female 5-ASR was 2.33%, 1.51%, 3.35%, 3.92%, 3.84%, 7.18%, 11.45%, and 29.84%, respectively. There was a statistically significant difference in RSR between males and females (χ (2) = 45.68, P < 0.001). The 5-RSR for each age group of 25-34 years old, 35-44 years old, 45-54 years old, 55-64 years old, 65-74 years old, and 75 years old were 4.92%, 5.29%, 8.17%, 11.70%, 11.63%, and 9.60%, respectively. There were statistically significant differences in RSR among different age groups (χ (2) = 501.29, P < 0.001). The AAPC in Qidong region from 1972 to 2019 for 1-ARS, 3-ASR, and 5-ARS were 5.26% (t = 12.35, P < 0.001), 8.10% (t = 15.99, P < 0.001), and 8.96 % (t = 16.06, P < 0.001), respectively. The upward trend was statistically significant in all cases. The AAPC of 5-ARS was 9.82% in males (t = 14.14, P < 0.001), and 8.79% in females (t = 11.48, P < 0.001), and the upward trend was statistically significant in both. The AAPC of 25-34 years old, 35-44 years old, 45-54 years old, 55-64 years old, 65-74 years old, and 75 years old were 5.37% (t = 5.26, P = 0.002), 5.22% (t = 5.66, P = 0.001), 7.20% (t = 6.88, P < 0.001), 10.00% (t = 12.58, P < 0.001), 9.96% (t = 7.34, P < 0.001) and 8.83% (t = 3.51, P = 0.013), and the upward trend was statistically significant. Conclusion: The overall survival rate of registered cases of liver cancer in the Qidong region's entire population has greatly improved, but there is still much room for improvement. Hence, constant attention should be paid to the study on preventing and treating liver cancer.

Recent progress and future prospects of treatment for peritoneal metastasis in gastric cancer / 中华胃肠外科杂志

Peritoneal metastasis is one of the most frequent patterns of metastasis in gastric cancer, and remains a major unmet clinical problem. Thus, systemic chemotherapy remains the mainstay of treatment for gastric cancer with peritoneal metastasis. In well-selected patients, the reasonable combination of cytoreductive surgery, hyperthermic intraperitoneal chemotherapy (HIPEC), and neoadjuvant intraperitoneal chemotherapy with systemic chemotherapy will bring significant survival benefits to patients with gastric cancer peritoneal metastasis. In patients with high-risk factors, prophylactic therapy may reduce the risk of peritoneal recurrence, and improves survival after radical gastrectomy. However, high-quality randomized controlled trials will be needed to determine which modality is better. The safety and efficacy of intraoperative extensive intraperitoneal lavage as a preventive measure has not been proven. The safety of HIPEC also requires further evaluation. HIPEC and neoadjuvant intraperitoneal and systemic chemotherapy have achieved good results in conversion therapy, and it is necessary to find more efficient and low-toxicity therapeutic modalities and screen out the potential benefit population. The efficacy of CRS combined with HIPEC on peritoneal metastasis in gastric cancer has been preliminarily validated, and with the completion of clinical studies such as PERISCOPE II, more evidence will be available.

Molecular mechanism and treatment strategy of colorectal cancer peritoneal metastasis / 中华胃肠外科杂志

Peritoneal metastatic colorectal cancer (pmCRC) is common and has been considered as the terminal stage. The theory of "seed and soil" and "oligometastasis" are the acknowledged hypotheses of pathogenesis of pmCRC. In recent years, the molecular mechanism related to pmCRC has been deeply researched. We realize that the formation of peritoneal metastasis, from detachment of cells from primary tumor to mesothelial adhesion and invasion, depends on the interplay of multiple molecules. Various components of tumor microenvironment also work as regulators in this process. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have been widely used in clinical practice as an established treatment for pmCRC. Besides systemic chemotherapy, targeted and immunotherapeutic drugs are also increasingly used to improve prognosis. This article reviews the molecular mechanisms and treatment strategies related to pmCRC.

Establishment of treatment center for peritoneal metastasis in colorectal cancer / 中华胃肠外科杂志

The prognosis of patients with peritoneal metastasis from colorectal cancer is poor. At present, the comprehensive treatment system based on cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) has significantly improved the survival of these patients. However, CRS and HIPEC have strict indications, high procedural difficulty, and high morbidity and mortality. If CRS+HIPEC is performed in an inexperienced center, overall survival and quality of life of patients may bo compromised. The establishment of specialized diagnosis and treatment centers can provide a guarantee for standardized clinical diagnosis and treatment. In this review, we first introduced the necessity of establishing a colorectal cancer peritoneal metastasis treatment center and the construction situation of the diagnosis and treatment center for peritoneal surface malignancies at home and abroad. Then we focused on introducing our construction experience of the colorectal peritoneal metastasis treatment center, and emphasized that the construction of the center must be done well in two aspects: firstly, the clinical optimization should be realized and the specialization of the whole workflow should be strengthened; secondly, we should ensure the quality of patient care and the rights, well-being and health of every patient.

Construction and evaluation of a nomogram for predicting the prognosis of patients with colorectal cancer with peritoneal carcinomatosis treated with cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy / 中华胃肠外科杂志

Objectives: To construct a nomogram incorporating important prognostic factors for predicting the overall survival of patients with colorectal cancer with peritoneal metastases treated with cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC), the aim being to accurately predict such patients' survival rates. Methods: This was a retrospective observational study. Relevant clinical and follow-up data of patients with colorectal cancer with peritoneal metastases treated by CRS + HIPEC in the Department of Peritoneal Cancer Surgery, Beijing Shijitan Hospital, Capital Medical University from 2007 January to 2020 December were collected and subjected to Cox proportional regression analysis. All included patients had been diagnosed with peritoneal metastases from colorectal cancer and had no detectable distant metastases to other sites. Patients who had undergone emergency surgery because of obstruction or bleeding, or had other malignant diseases, or could not tolerate treatment because of severe comorbidities of the heart, lungs, liver or kidneys, or had been lost to follow-up, were excluded. Factors studied included: (1) basic clinicopathological characteristics; (2) details of CRS+HIPEC procedures; (3) overall survival rates; and (4) independent factors that influenced overall survival; the aim being to identify independent prognostic factors and use them to construct and validate a nomogram. The evaluation criteria used in this study were as follows. (1) Karnofsky Performance Scale (KPS) scores were used to quantitatively assess the quality of life of the study patients. The lower the score, the worse the patient's condition. (2) A peritoneal cancer index (PCI) was calculated by dividing the abdominal cavity into 13 regions, the highest score for each region being three points. The lower the score, the greater is the value of treatment. (3) Completeness of cytoreduction score (CC), where CC-0 and CC-1 denote complete eradication of tumor cells and CC-2 and CC-3 incomplete reduction of tumor cells. (4) To validate and evaluate the nomogram model, the internal validation cohort was bootstrapped 1000 times from the original data. The accuracy of prediction of the nomogram was evaluated with the consistency coefficient (C-index), and a C-index of 0.70-0.90 suggest that prediction by the model was accurate. Calibration curves were constructed to assess the conformity of predictions: the closer the predicted risk to the standard curve, the better the conformity. Results: The study cohort comprised 240 patients with peritoneal metastases from colorectal cancer who had undergone CRS+HIPEC. There were 104 women and 136 men of median age 52 years (10-79 years) and with a median preoperative KPS score of 90 points. There were 116 patients (48.3%) with PCI≤20 and 124 (51.7%) with PCI>20. Preoperative tumor markers were abnormal in 175 patients (72.9%) and normal in 38 (15.8%). HIPEC lasted 30 minutes in seven patients (2.9%), 60 minutes in 190 (79.2%), 90 minutes in 37 (15.4%), and 120 minutes in six (2.5%). There were 142 patients (59.2%) with CC scores 0-1 and 98 (40.8%) with CC scores 2-3. The incidence of Grade III to V adverse events was 21.7% (52/240). The median follow-up time is 15.3 (0.4-128.7) months. The median overall survival was 18.7 months, and the 1-, 3- and 5-year overall survival rates were 65.8%, 37.2% and 25.7%, respectively. Multivariate analysis showed that KPS score, preoperative tumor markers, CC score, and duration of HIPEC were independent prognostic factors. In the nomogram constructed with the above four variables, the predicted and actual values in the calibration curves for 1, 2 and 3-year survival rates were in good agreement, the C-index being 0.70 (95% CI: 0.65-0.75). Conclusions: Our nomogram, which was constructed with KPS score, preoperative tumor markers, CC score, and duration of HIPEC, accurately predicts the survival probability of patients with peritoneal metastases from colorectal cancer treated with cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy.

Effects of laparoscopic hyperthermic intraperitoneal perfusion chemotherapy combined with intraperitoneal and systemic chemotherapy treatment in patients with untreated gastric cancer with peritoneal metastasis / 中华胃肠外科杂志

Objective: To investigate the efficacy of laparoscopic hyperthermic intraperitoneal perfusion chemotherapy combined with intraperitoneal and systemic chemotherapy (HIPEC-IP-IV) in the treatment of peritoneal metastases from gastric cancer (GCPM). Methods: This was a descriptive case series study. Indications for HIPEC-IP-IV treatment include: (1) pathologically confirmed gastric or esophagogastric junction adenocarcinoma; (2) age 20-85 years; (3) peritoneal metastases as the sole form of Stage IV disease, confirmed by computed tomography, laparoscopic exploration, ascites or peritoneal lavage fluid cytology; and (4) Eastern Cooperative Oncology Group performance status 0-1. Contraindications include: (1) routine blood tests, liver and renal function, and electrocardiogram showing no contraindications to chemotherapy; (2) no serious cardiopulmonary dysfunction; and (3) no intestinal obstruction or peritoneal adhesions. According to the above criteria, data of patients with GCPM who had undergone laparoscopic exploration and HIPEC from June 2015 to March 2021 in the Peking University Cancer Hospital Gastrointestinal Center were analyzed, after excluding those who had received antitumor medical or surgical treatment. Two weeks after laparoscopic exploration and HIPEC, the patients received intraperitoneal and systemic chemotherapy. They were evaluated every two to four cycles. Surgery was considered if the treatment was effective, as shown by achieving stable disease or a partial or complete response and negative cytology. The primary outcomes were surgical conversion rate, R0 resection rate, and overall survival. Results: Sixty-nine previously untreated patients with GCPM had undergone HIPEC-IP-IV, including 43 men and 26 women; with a median age of 59 (24-83) years. The median PCI was 10 (1-39). Thirteen patients (18.8%) underwent surgery after HIPEC-IP-IV, R0 being achieved in nine of them (13.0%). The median overall survival (OS) was 16.1 months. The median OS of patients with massive or moderate ascites and little or no ascites were 6.6 and 17.9 months, respectively (P<0.001). The median OS of patients who had undergone R0 surgery, non-R0 surgery, and no surgery were 32.8, 8.0, and 14.9 months, respectively (P=0.007). Conclusions: HIPEC-IP-IV is a feasible treatment protocol for GCPM. Patients with massive or moderate ascites have a poor prognosis. Candidates for surgery should be selected carefully from those in whom treatment has been effective and R0 should be aimed for.

Treatment outcomes of retinoblastoma patients at a Tertiary Government Hospital in the Philippines

Objective@#This study determined the treatment outcomes of patients with retinoblastoma seen at a Philippine tertiary government hospital from January 2000 to January 2020.@*Method@#This is a cohort study. Medical records of patients with histopathologic-proven retinoblastoma were reviewed and pertinent information on clinical profile and presentation, treatment and outcomes were recorded.@*Results@#This study included 118 patients (146 eyes) with mean age at symptom onset of 7.4 + 6.6 months and mean age at consult of 11.5 + 13.7 months. There were 69 (47%) eyes with International Classification of Retinoblastoma (ICRB) stage E. The most common primary treatment was enucleation (n=137, 94%). The most common high-risk histopathologic feature was involvement of the optic nerve at the cut-end section (n=27, 34%). Only 14 patients (11%) completed treatment with median follow-up of 30.5 months (range 4- 122). @*Conclusion@#The rate of overall survival of patients with retinoblastoma is low in this study, similar to other developing countries. This can be due to higher proportion of patients with advanced stage at presentation and lower percentage of treatment completion. Early diagnosis and treatment may lead to better survival rate, visual outcome and quality of life. Due to limited data on follow-up, globe preservation could not be determined.

Analysis of relevant factors influencing the 30-day survival rate of patients with cardiac arrest and cardiopulmonary resuscitation: research based on 8-year data of a class III hospital / 中华危重病急救医学

OBJECTIVE@#To investigate the survival of patients with cardiac arrest and cardiopulmonary resuscitation (CA-CPR), and to analyze the factors influencing survival at 30 days after restoration of spontaneous circulation (ROSC).@*METHODS@#A retrospective cohort study was conducted. Clinical data of 538 patients with CA-CPR admitted to the People's Hospital of Ningxia Hui Autonomous Region from January 2013 to September 2020 were enrolled. The gender, age, underlying disease, cause of CA, type of CA, initial rhythm, presence or absence of endotracheal intubation, defibrillation, use of epinephrine, and 30-day survival rate of patients were collected. The etiology of CA and 30-day survival rate among patients with different ages were compared, as well as the clinical data between patients who survived and died at 30 days after ROSC were also compared. Multivariate Logistic regression was used to analyze the relevant factors affecting the 30-day survival rate of patients.@*RESULTS@#Among 538 patients with CA-CPR, 67 patients with incomplete information were excluded, and 471 patients were enrolled. Among 471 patients, 299 were males and 172 were females. Aged from 0 to 96 years old, 23 patients (4.9%) were < 18 years old, 205 patients (43.5%) were 18 to 64 years old, and 243 patients (51.6%) were ≥ 65 years old. 302 cases (64.1%) achieved ROSC, and 46 patients (9.8%) survived for more than 30 days. The 30-day survival rate of patients aged < 18 years old, 18-64 years old and ≥ 65 years old was 8.7% (2/23), 12.7% (26/205) and 7.4% (18/243), respectively. The main causes of CA in patients younger than 18 years were severe pneumonia (13.1%, 3/23), respiratory failure (13.1%, 3/23), and trauma (13.1%, 3/23). The main causes were acute myocardial infarction (AMI; 24.9%, 51/205), respiratory failure (9.8%, 20/205), and hypoxic brain injury (9.8%, 20/205) in patients aged 18-64 years old, and AMI (24.3%, 59/243) and respiratory failure (13.6%, 33/243) in patients aged ≥ 65 years old. Univariate analysis results revealed that the 30-day survival rate of patients with CA-CPR may be related to the the cause of CA was AMI, initial rhythm was ventricular tachycardia/ventricular fibrillation, endotracheal intubation and epinephrine. Multivariate Logistic regression analysis results showed that CA was caused by AMI [odds ratio (OR) = 0.395, 95% confidence interval (95%CI) was 0.194-0.808, P = 0.011] and endotracheal intubation (OR = 0.423, 95%CI was 0.204-0.877, P = 0.021) was a protective factor for 30 days of survival after ROSC in patients with CA-CPR.@*CONCLUSIONS@#The 30-day survival rate of CA-CPR patients was 9.8%. The 30-day survival rate of CA-CPR patients with AMI after ROSC is higher than that of patients with other CA causes, and early endotracheal intubation can improve the prognosis of patients.

An analysis of long-term survival trends for nasopharyngeal carcinoma in Qidong, Jiangsu / 中华肿瘤杂志

Objective: To analyze the survival of nasopharyngeal carcinoma patients in Qidong from 1972 to 2016, and provide a basis for the prognosis evaluation and prevention for nasopharyngeal carcinoma patients. Methods: A total of 1 060 registered nasopharyngeal carcinoma patients were followed up for survival outcomes until December 31, 2021. Observed survival rate (OSR) and relative survival rate (RSR) was calculated by Hakulinen method in SURV3.01 software, and Hakulinen's likelihood ratio test was used for statistical difference comparison. Age-standardized relative survival rate (ARSR) was calculated according to the International Cancer Survival Standard (ICSS). Joinpoint 4.7.0.0 software was used to conduct the annual average percentage change (AAPC) in nasopharyngeal carcinoma survival rate. The period from 1972 to 2016 is divided into 9 periods for grouping processing according to 5 years. Results: The OSR of nasopharyngeal carcinoma at 1, 5, 10 years were 63.02%, 34.70% and 24.72%, the RSR at 1, 5, 10 years were 64.44%, 38.98% and 31.64%, respectively. The uptrends of RSR in the nine periods were statistically significant (χ(2)=112.16, P<0.001). The 1, 5, 10 years RSR for males were 62.66%, 35.89% and 27.94%, while the 1, 5, 10 years RSR for females were 68.30%, 45.67% and 39.68%, respectively. There was no statistically significant difference in RSR between males and females (χ(2)=14.16, P=0.656). The 5-year RSR for the age groups of 25-34, 35-44, 45-54, 55-64, 65-74, and over 75 years old were 52.83%, 40.92%, 42.64%, 38.65%, 27.23% and 28.88%, respectively. There was a statistically significant difference in RSR among different age groups (χ(2)=42.33, P=0.003). Moreover, the ARSR of nasopharyngeal carcinoma at 1, 5, 10 years were 63.64%, 37.33% and 27.10%, for males were 61.82%, 35.60% and 25.20%, for females were 68.36%, 43.12% and 32.93%. Period trend showed that the AAPC of 5-ARSR was 2.71% (t=7.47, P<0.001) from 1972 to 2016 in Qidong. The AAPC of 5-ARSR in males and females were 2.63% (t=4.98, P=0.002) and 2.71% (t=6.08, P=0.001). There was statistically significant increase in 5-year ARSR among both genders. Furthermore, the AAPC of 5-year RSR among 25-34, 35-44, 45-54, 55-64, 65-74 and 75+ years old were 2.16% (t=4.28, P=0.004), 3.38% (t=5.06, P=0.001), 1.99% (t=2.82, P=0.026), 2.82% (t=3.39, P=0.012), 2.20% (t=2.82, P=0.026) and -0.91% (t=-0.42, P=0.689), respectively. Except for the 75+ years old age group, the other age groups were significantly upward trend. Conclusions: The overall survival rate of nasopharyngeal carcinoma in Qidong from 1972 to 2016 has shown an upward trend. It is necessary to introduce standardized multi-disciplinary treatment mode to improve treatment effect and survival rate.
