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.

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.

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)

Antecedentes: El autoinjerto de válvula pulmonar (VP) u operación de Ross (OpR) tiene excelentes resultados a largo plazo. Es superior a otros tipos de reemplazo valvular en jóvenes adultos, aunque no el estándar de primera línea. Un tiempo quirúrgico prolongado o alta morbimortalidad son importantes preocupaciones. Objetivos: Establecer la morbimortalidad asociada a la OpR por un período >10 años, considerando el tiempo quirúrgico, tasa de reoperación y supervivencia global (SG). Métodos: Cohorte prospectiva (1996-2012), en seguimiento hasta agosto-2023. La SG fue estimada desde la OpR hasta la última consulta o deceso. Mediante regresión de Cox (Hazard Ratio, HR) se estimaron factores asociados a la SG. Resultados: La serie consta de 161 pacientes: 118 de etiología congénita (73.3%), 17 infecciosa (10.6%), 26 reumática (16.1%). La lesión fue estenótica en 79 (49.1%), insuficiencia en 40 (24.8%), mixta en 42 (26.1%). La OpR fue urgente en 11 (6.8%). The median time of ECC and the operation was 149 y 232 minutos, respectivamente. Veintisiete pacientes requirieron reoperación (16.8%). Con una mediana de 19.7 años (17.2-22.2), 23 pacientes fallecieron (14.3%): 1/23 asociado a OpR, 17/23 por causa cardiovascular y 5/23 por causas no cardiovasculares. La lesión mixta se asoció a mayor mortalidad (HR 3.07; IC 95% 1.11-8.47; p=.029). Conclusiones: La OpR es un procedimiento con baja morbimortalidad. La lesión mixta es un factor de riesgo independiente de mayor mortalidad. Sin embargo, la mediana de tiempo de CEC y quirúrgico es prolongado frente a otras técnicas de reemplazo valvular.


Background: Pulmonary valve (PV) autograftor reoperation or Ross surgery (RS), presents excellent long-term results. It is superior to other types of PV replacement in young adults, although it is not the first-line gold standard. A longer operative time or high morbidity and mortality rates are important concerns. Aim: To establish the morbidity and mortality associated with RS for >10 years, considering operative time, reoperation rate and overall survival (OS). Methods: Prospective cohort (1996-2012), with a follow-up until August/2023. The OS was estimated from RS to the last consultation/death. Factors associated to OS were estimated using Cox regression (Hazard Ratio, HR) Results: 161 patients were included: the etiology was congenital (118, 73%), infectious (17, 10.6%), and rheumatic (26,16.1%). The lesion was stenotic in 79 (49.1%), heart failure in 40 (24.8%), mixed in 42 (26.1%). RS was urgent in 11 (6.8%). Extracorporeal circulation (ECC) and operative times were 149 and 232 minutes, respectively. Twenty-seven patients required reoperation (16.8%). With a median follow up of 19.7 years (17.2-22.2), 23 patients died (14.3%): 1/23 associated with RS, 17/23 due to cardiovascular causes, and 5/23 due to non-cardiovascular causes. Mixed injury was associated with higher mortality (HR 3.07; 95% CI 1.11-8.47; p=.029). Conclusions: RS is a procedure with low morbidity and mortality. Mixed injury is an independent risk factor for increased mortality. However, the median ECC and operative times were higher compared to other valvular replacement techniques.

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.

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.

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.

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. This guideline is guided by the concept of integrative medicine and focuses on the domestic epidemiology, genetic background and original studies. It emphasizes the multidisciplinary team to holistic integrative medicine (MDT to HIM), and pays attention to the whole-course management of "prevention, screening, diagnosis, treatment, and rehabilitation". This guideline mainly focuses on peritoneal metastasis from gastrointestinal tumours, aiming to standardize the clinical diagnosis and treatment process, and jointly promote the management of peritoneal metastasis in China.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Introduction: The relationship between the tumor inflammatory infiltrate, also known as tumor-infiltrating lymphocytes (TILs), and invasive breast carcinomas has been extensively studied in recent years to verify its association with prognosis and response to treatment. The goal of this study was to associate the presence of TILs with patient's survival time. Methods: We studied prognostic clinicopathological characteristics already established in the literature and their impact on overall five-year survival time of patients with invasive breast cancer treated at Hospital Santa Casa in Belo Horizonte, Minas Gerais, Brazil, in 2011 (n=290). This was an observational and retrospective study. Results: The presence of TILs was associated with tumors of no special type (p=0.018) and with younger age of the patients (p=0.042). Smaller tumor size (HR: 19.24; 95%CI 4.30­86.15; p<0.001), absence of metastasis to the axillary lymph nodes (HR: 2.80; 95%CI 1.02­7.70; p=0.002), positivity for progesterone receptor (HR: 0.39; 95%CI 0.17­0.87; p=0.022), and presence of TILs (HR: 0.23; 95%CI 0.08­0.65; p=0.005) were associated with longer survival times. Conclusions: This study suggests that the presence of TILs, along with other clinicopathological characteristics, is a prognostic factor in breast cancer

Introduction: Childhood cancer is a small proportion of all cancers but is still a major public health problem. Objective: To describe the 5-year incidence and mortality rates and net survival of childhood cancer in Uruguay. Method: Data on all malignant tumors diagnosed in children aged 0-14 were included for the period 2011-2015, obtained from the National Pediatric Registry of Cancer and from the Ministry of Health Mortality Registry, classified according to the International Classification of Childhood Cancer (ICCC-3). Information on the total population was obtained from national census records. Follow up was made until December 2020. Results: The standardized incidence rate was 128/million children per year. The distribution of the disease was similar to developed countries. The overall mortality rate was 28.2/million, with a net overall survival of 79.6% for the total population. Conclusion: Childhood cancer incidence in Uruguay is similar to developed countries. Progress in diagnosis and care have improved survival immensely, but efforts must continue to keep this trend and ameliorate the outcomes.

Synthetic herbicides have been intensively used in weed control, although often involved in environmental contamination, critically affecting non-target species. However, never was investigated the effect of commercial formulation using atrazine on developing juvenile fish exposed for 35 days. Juveniles (Astyanax altiparanae) (n = 600) were assigned to the following ATZ-exposed groups: 0 (CTR-control), 0.56 (ATZ0.56), 1.00 (ATZ1.00), 1.66 (ATZ1.66) and 11.66 (ATZ11.66) µg/L. We found a 36.6% decrease in juvenile survival rate in the ATZ11.66 group compared to control and other groups. Juveniles from ATZ11.66 also showed hyperglycemia and increased cortisol levels. Increased the imbalance oxidative with an increase in malondialdehyde (MDA) and Carbonylated proteins levels markers in muscle, gills, and liver. We also found increased activity of the antioxidant enzymes superoxide dismutase (SOD) in gills and SOD and catalase (CAT) in muscles from ATZ11.66 fish, and increased glutathione S-transferase (GST) activities in the liver from all exposed groups compared to control. The morphological consequences of this were loss of secondary lamella integrity, increased mucus-secreting cells, hyperplasia, and lamellar fusion, as well as increased aneurysms percentage. The liver showed vascular congestion associated with endothelial hyperplasia, steatosis, and a decrease in the nuclei percentage. Our results showed that exposure to a commercial formulation of ATZ at 11.66 µg/L can be causing an imbalance in the oxidative markers and morphological damages and decreased survival in a juvenile Neotropical species of great ecological relevance and commercial interest.
