ABSTRACT
Abstract Introduction : Although therapeutic advances have improved results of cutaneous melanoma (CM), senti nel node-positive patients still have substantial risk to develop recurrent disease. We aim to investigate prog nostic indicators associated with disease recurrence in positive-sentinel lymph node biopsy (SLNB) patients in a Latin-American population. Methods : Retrospective analysis of CM patients and positive-SLNB (2010-2020). Patients were divided into two groups: Group A (completion lymph node dissection, CLND), Group B (active surveillance, AS). Association of demographics, tumor data and SLN features with recurrence-free (RFS), distant metastases-free (DMFS) and melanoma specific (MSS) survival was analyzed. Results : Of 205 patients, 45 had a positive SLNB; 27(60%) belonged to Group A and 18(40%) to Group B. With a median follow-up of 36 months, 16 patients (12 in Group A and 4 in Group B) developed recurrent dis ease and estimated 5-yr RFS at any site was 60% (CI95%, 0.39 - 0.77) (44.5% in CLND group vs. 22% in AS group; P = 0.20). Estimated 5-yr DMFS and MSS: 65% (CI 95%, 0.44 - 0.81) and 73% (CI 95%, 0.59 - 0.89) with no differ ences between groups (p = 0.41 and 0.37, respectively). Independent predictors of poorer MSS were extranodal extension (ENE) and MaxSize > 2 mm of melanoma deposit in SLN. Factors independently associated with DMFS: Breslow depth > 2 mm, ENE, number (≥ 2) of posi tive SN and CLND status. Conclusion : Primary tumor and SN features in mela noma provide important prognostic information that help optimize prognosis and clinical management. AS is now the preferred approach for most positive-SLNB CM patients.
Resumen Introducción : Si bien los avances terapéuticos han permitido mejorar los resultados del melanoma cutáneo (MC), los pacientes con ganglio centinela positivo (BGCP) aún tienen riesgo elevado de desarrollar recurrencia de la enfermedad. Nuestro objetivo fue investigar in dicadores pronósticos asociados a dicho evento en una población latinoamericana. Métodos : Análisis retrospectivo de pacientes con MC y BGCP entre 2010-2020. Los pacientes se dividieron en 2 grupos: Grupo A (linfadenectomía terapéutica) y Grupo B (Vigilancia activa, VA). Se analizaron datos demográficos, tumorales y características del GC junto con sobrevida-libre de recurrencia (SLR), libre de metástasis a distancia (SLMD) y específica de melanoma (SEM). Resultados : De 205 pacientes, 45 presentaron BGCP; 27 (60%) perteneció al Grupo A y 18 (40%) al Grupo B. Con una mediana de seguimiento de 36 meses, 16 pa cientes (12 en Grupo A y 4 en Grupo B) desarrollaron enfermedad recurrente con una SLR a 5 años de 60% (IC95%: 0.39-0.77) (44.5% en Grupo B vs. 22% en Grupo A; P = 0.20). Las SLMD y SEM estimadas a 5 años fueron de 65% (CI 95%, 0.44 - 0.81) y 73% (CI 95%, 0.59 - 0.89) sin diferencias entre ambos grupos (p = 0.41 y 0.37, respec tivamente). Los predictores independientes de peor SEM fueron: extensión extranodal (ENE) y MaxSize > 2mm de depósito tumoral en GC. Los factores asociados de forma independiente con SLMD fueron Breslow >2mm, ENE, número (≥ 2) de GC positivos y el status (positividad) de la linfadenectomía. Conclusión : Características del tumor primario y del GC brindan información importante que ayuda a optimi zar el pronóstico y manejo clínico de los pacientes con MC. La VA es actualmente el abordaje de elección para la mayoría de los pacientes con BGCP.
ABSTRACT
Objective To observe the severity of cerebral edema after mechanical thrombectomy in the patients with acute ischemic stroke caused by large vessel occlusion,and to statistically analyze the related fac-tors affecting the prognosis quality of the patients,so as to guide the patients to conduct scientific interven-tion.Methods Ninety-one patients with acute ischemic stroke due to anterior circulation large vessel occlusion treated with mechanical thrombectomy in this hospital from October 2021 to October 2022 served as the ana-lytic subjects.According to the severity of brain edema,they were divided into the group Ⅰ(mild),group Ⅱ(moderate),and group Ⅲ(severe);after 12-week treatment,the improved Rankin scale was used to evaluate the prognosis.The patients with good prognosis were included in the excellent group,and the patients with poor prognosis were included in the poor group.Single factor and multifactor logistic analysis was used to ana-lyze the influencing factors and prognostic related factors of different degrees of brain edema.Results The univariate analysis showed that the percentage of patients with NIHSS score at admission ≥15,time from on-set to thrombolysis ≥6 h,history of hypertension,successful vascular recanalization and good collateral circu-lation were significantly different among the groups Ⅰ,Ⅱ and Ⅲ(P<0.05);the multivariate logistic regres-sion analysis results showed that the NIHSS score at admission ≥15,time from onset to thrombolysis ≥6 h,and hypertension history were the risk factors leading to severe cerebral edema,while successful recanalization of blood vessels was a protective factor for cerebral edema(P<0.05).The univariate analysis showed that in the good prognosis group the percentage of patients had good circulation of lateral branches,successful reca-nalization of blood vessels,severe cerebral edema,hypertension,time from onset to thrombolysis ≥6 h,and NIHSS score ≥15 at admission were significantly different from those in the poor prognosis group(P<0.05).The multivariate logistic regression analysis results showed that severe cerebral edema,time from onset to thrombolysis ≥6 h and NIHSS score ≥15 at admission were the risk factors for poor prognosis,while good collateral circulation and successful recanalization of blood vessels were the positive factors for good prognosis(P<0.05).Conclusion Mechanical thrombectomy patients with hypertension and time from onset to throm-bolysis ≥6 h and NIHSS score at admission ≥15 have more severe brain edema after treatment;severe brain edema,time from onset to thrombolysis ≥6 h,NIHSS score at admission ≥15 were the adverse factors affect-ing the prognosis of the patients with mechanical thrombectomy.
ABSTRACT
【Objective】 To construct a nomogram survival prediction model for patients with locally advanced renal cell carcinoma based on SEER database (n=7893), so as to provide reference for future prognosis study. 【Methods】 Case data were downloaded from the SEER database, and divided into the experimental group and validation group with a ratio of 7∶3 by simple randomization.The clinical information was analyzed, independent risk factors influencing prognosis were screened, and the overall survival (OS) and tumor-specific survival (CSS) were mapped.Model performance was evaluated using consistency index, area under the receiver operating characteristic curve (AUC), internal and external validation, and calibration curves. 【Results】 Patients’ age, tumor size, disease progression tpye, TNM stage, number of positive lymph nodes, marital status and pathological type were significantly correlated with OS and CSS (P<0.01).Based on the above predictors, the internal verification AUC of the 1-, 3- and 5- year OS nomogram model was 0.809, 0.721 and 0.715, respectively.The internal validation AUC of the nomogram model for 1-, 3- and 5- year CSS was 0.802, 0.745 and 0.735, respectively.The external validation AUC of the OS nomogram model was 0.792, 0.628 and 0.620 at 1, 3 and 5 years, respectively, and the external validation AUC of CSS was 0.943, 0.803 and 0.737 at 1.3 and 5 years, respectively, showing good model differentiation and accuracy. 【Conclusion】 The prediction performance of the nomogram model is good, and it can provide reference for individualized treatment.
ABSTRACT
Objective To identify the clinical characteristics and prognostic factors of young patients with sporadic rectal cancer liver metastasis(RCLM).Methods The clinical data of young RCLM patients at 45 years or under(n=40,as younger patient group)in Peking University First Hospital from January 2016 to January 2021 were reviewed,meanwhile,elder RCLM patient group were comprised of 82 patients older than 45-year-old in a 1:2 ratio.Proportions of categorical variables were compared between young patients and old patients.The clinicopathologic parameters were analyzed with univariate and multivariate Cox regression models and Kaplan-Meier method for demonstrating survival differences between the maximum diameter of liver metastasis and local therapy.Results One hundred and twenty-two RCLM patients were identified,the 1-,3-and 5-year survival rates of young patient group were 97.5%,47.5%,15.0%,those of elder patient group were 84.1%,26.8%,9.8%,respectively.The differences in BMI(P=0.008),primary tumor with obstruction and bleeding(P=0.006),synchronous rectal cancer liver metastases(P=0.005),the maximum diameter of liver metastasis>3 cm(P=0.019)were statistically significant between the two groups.And univariate and multivariate analyses showed that age(P=0.003),N stage(P=0.007),local therapy for liver metastases(P=0.047)and the maximum diameter of liver metastasis(P=0.030)were independent risk factors for influencing the prognosis of RCLM patients;curative resection or not of primary tumor(P=0.035)and the maximum diameter of liver metastasis(P=0.041)were independent risk factors for influencing the prognosis of young RCLM patients.Kaplan-Maier curve demonstrated survival differences between the maximum diameter of liver metastasis and local therapy for liver metastasis in RCLM patients(log-rank P=0.000).Conclusions Although with later staging of initial tumor station,young RCLM patients may obtain better survival benefit compared with old patients.Higher degree of lymph node metastasis,local therapy for liver metastases and the maximum diameter of liver metastasis>3 cm indicates poor prognosis in RCLM patients,and without curative resection of primary tumor and maximum diameter of liver metastasis are also considered as the independent poor prognostic factors of young RCLM patients.Local therapy for liver metastases appears to play an important role in the treatment strategy of RCLM patients.

Purpose: To determine the factors affecting the visual outcome after surgical repair of limbal corneal lacerations at a tertiary eye care center in South India. Methods: A retrospective analysis of patients diagnosed with limbal tears between 2011 and 2021 was conducted. Demographic information such as age, gender, cause of injury, and size of the laceration was recorded. Comprehensive ocular examination was performed, including gentle B scan evaluation whenever not contraindicated for detailed posterior segment evaluation. Only those cases with a minimum follow?up of one year were included. Postoperative best?corrected visual acuity, intraocular pressure (IOP), cornea clarity, and integrity of the wound at last follow?up were noted. Results: Out of the 20 patients, 15 (75%) were males and 5 (25%) were females. The mean age was 42.6 � 22.4 years. All 20 patients had a penetrating injury, with four (20%) injured by a stick, two (10%) by an iron rod, three (15%) due to road traffic accident (RTA), three (15%) by glass, and eight (40%) with other nonspecific objects [two (10%) with needle, two (10%) with elastic rope, two (10%) with bangle, and two (10%) with metal]. The average time between the injury and the surgery was 48 hours (2 days). Four (20%) patients underwent a second surgery within a week of repair. After limbal tear repair, at final follow?up at 3 years, 7 (35%) had VA worse than 20/800, 3 (15%) had VA between 20/100 and 20/800, and 10 (50%) achieved VA better than 20/80. Conclusion: Preoperative visual acuity (VA), mode of injury, and size of wound affect the final visual outcome after surgical repair of limbal corneal laceration. Preoperative VA and mode of injury were statistically significant even in the multivariate analysis.
ABSTRACT
Background: Bullous pemphigoid is the most common subepidermal autoimmune blistering disease. Till now, the reported prognostic factors in bullous pemphigoid vary considerably. Aims: The purpose of this study was to determine the overall survival rate and prognostic factors in bullous pemphigoid. Methods: We conducted a retrospective cohort study on newly diagnosed bullous pemphigoid patients between July 2001 and November 2019 in a referral unit for autoimmune blistering skin diseases in Romania. Results: One hundred forty-eight patients were included in the study. The Kaplan–Meier overall survival rates at 1, 3, 5 and 10 years were respectively 74.2% (95% confidence interval, 67.5–81.6%), 53.4% (45.7–62.2%), 43.6% (35.9–53%) and 31.3% (23.5–41.7%). The median follow-up among survivors was 48 months (interquartile range: 11–150). Ninety (60.8%) patients died during the follow-up period; of them, 38 (42.2%) had active disease at the time of death. Advanced age, neurological diseases, valvular heart disease, malignancies, use of statins, skin infections and extensive cutaneous involvement were linked to poorer outcomes, while the use of topical corticosteroids was associated with increased overall survival. Limitations: This study lacks a control cohort to validate the obtained results. It was conducted in a retrospective manner in a single centre. In addition, indirect immunofluorescence microscopy was not performed in all patients. Conclusion: Beyond ageing and neurological comorbidities, the prognosis of bullous pemphigoid patients was significantly influenced by the presence of skin infections, valvular heart disease, use of statins and extensive cutaneous involvement. Topical corticosteroid treatment was associated with increased survival in these patients
ABSTRACT
Aim: Surgical correction of congenital heart defects (CHD) often requires interruption of blood flow through cardiopulmonary bypass (CPB) and aortic cross-clamping (ACC), for which duration(s) are considered to be prognostic factors, along with intensive care unit (ICU) length of stay (ICULOS). The aim of this study was to evaluate these surgical prognostic factors in pediatric patients with different types of CHD regarding their type of lesion and associated genetic factors. Study Design: Cross-sectional cohort study with 307 pediatric patients. Place and Duration of Study: Pediatric Intensive Care Unit (ICU) of Hospital da Criança Santo Antônio, in Porto Alegre/RS, Brazil, from 2006-2009 (3 years) Methodology: After inclusion criteria, we studied 266 pediatric patients admitted for the first time in a reference cardiac pediatric ICU from Southern Brazil following cardiac surgery. Intraoperative prognostic factors such as duration of CPB, ACC and ICULOS, in addition to dysmorphological and cytogenetic examinations were compiled and analyzed. P-values of <0.05 were considered significant. Results: CPB time was associated to four outflow tract defects (Tetralogy of Fallot [ToF], transposition of the great arteries [TGA], double outlet right ventricle, and truncus arteriosus [TA]), atrioventricular septal defect, and hypoplastic left heart syndrome (HLHS) (P < 0.001). ACC duration was associated with three outflow tract defects (ToF, TGA, and TA) and HLHS (P < 0.001). Moreover, CPB and ACC times showed an association with cyanotic and complex heart defects, as well as prolonged ICULOS (P < 0.001). There was no relationship between these prognostic factors and syndromic aspects or cytogenetic findings. Conclusions: CHD type has an impact over CPB and ACC duration and ICULOS, whereas genetic factors are not associated with those prognostic factors.
ABSTRACT
Fundamento: el análisis estadístico implicativo surgió en los años 80 para resolver problemas de la didáctica de las matemáticas. Recientemente se fundamentó su empleo en las Ciencias Médicas para identificar factores de riesgo y pronósticos. Objetivo: evaluar la utilidad del análisis estadístico implicativo en la identificación de los factores pronósticos que más inciden en la mortalidad por linfomas en niños y adolescentes. Método: se realizó un estudio de casos y controles en niños y adolescentes con diagnóstico de linfoma Hodgkin y no Hodgkin atendidos en el Hospital Docente Pediátrico Sur Dr. Antonio María Béguez César de Santiago de Cuba en el período de enero 2008 a enero 2021. Se analizó como variable dependiente el estado del paciente fallecido o vivo al momento del estudio y como covariables se tomaron: el estadio de mal pronóstico, la presencia de síntomas B, el subtipo histológico, la presencia de tres o más sitios extraganglionares, la metástasis, edad y presencia de masa tumoral. Se aplicaron dos técnicas estadísticas, la regresión logística binaria y el análisis estadístico implicativo. Resultados en los casos fue más frecuente el linfoma no Hodgkin mientras que en los controles predominó el Hodgkin. Ambas técnicas reconocieron el subtipo histológico y la afectación extraganglionar como factores pronósticos desfavorables. El análisis estadístico implicativo reconoció además el estadio y la presencia de metástasis. Conclusión: el análisis estadístico implicativo es una técnica que complementa la regresión logística binaria en la identificación de factores pronósticos, lo que permite mejor comprensión de la causalidad.
Background: the implicative statistical analysis arose in the 80s to solve problems in the didactics of mathematics. Its use in the Medical Sciences to identify risk factors and prognoses was recently founded. Objective: to evaluate the usefulness of the implicative statistical analysis in the identification of the prognostic factors that most affect mortality from lymphomas in children and adolescents. Method: a case-control study was carried out in children and adolescents diagnosed with Hodgkin and non-Hodgkin lymphoma treated at the Dr. Antonio María Béguez César Sur Pediatric Teaching Hospital in Santiago de Cuba from January 2008 to January 2021. The state of the deceased or alive patient at the time of the study was analyzed as the dependent variable and the following were taken as covariates: poor prognosis stage, presence of B symptoms, histological subtype, presence of three or more extranodal sites, metastasis, age and presence of tumor mass. Two statistical techniques were applied: binary logistic regression and implicative statistical analysis. Results: non-Hodgkin's lymphoma was more frequent in the cases, while Hodgkin's lymphoma predominated in the controls. Both techniques recognized the histological subtype and extranodal involvement as unfavorable prognostic factors. The implicative statistical analysis also recognized the stage and the presence of metastases. Conclusion: the implicative statistical analysis is a technique that complements the binary logistic regression in the identification of prognostic factors, which allows a better understanding of causality.
ABSTRACT
Objetivos: Reportar un caso de linfoma no Hodgkin de células B primario de mama (LPM) y realizar una revisión de la literatura de su diagnóstico y tratamiento. Materiales y métodos: Se reporta el caso de una paciente de 80 años que acudió a una institución privada de referencia en México por un LPM. Además, se diagnosticó un melanoma primario de hígado, mediante biopsia dirigida y estudio de patología. La paciente recibió tratamiento con R-CHOP (rituximab, ciclofosfamida, doxorrubicina, vincristina y prednisona), cuadrantectomía, resección de cadenas ganglionares y radioterapia. La paciente presenta adecuada respuesta del LPM, sin embargo, el segundo tumor primario progresa llevando a la paciente a cuidados paliativos. Se realizó una búsqueda bibliográfica en Medline vía PubMed, LILACS y Google Scholar. Se incluyeron estudios de cohortes, reportes y series de casos en pacientes con LPM que abordaran el diagnóstico, tratamiento y pronóstico de esta patología, publicados en inglés y español entre los años 2000 a 2022. Resultados: Se identificaron 23 títulos, de los cuales 17 cumplieron con los criterios de inclusión, estos fueron reportes de caso y series de caso. La mayoría de las pacientes recibió un esquema quimioterapéutico R-CHOP, el cual se complementó con radioterapia. Cerca del 80 % presentó remisión completa. El sitio más frecuente de recaída fue el sistema nervioso central. La sobrevida a 5 años fue del 83,6 % en los estudios incluidos. Conclusiones: En la actualidad, el esquema CHOP -con o sin rituximab- es el más empleado y el único que ha mostrado tener un impacto positivo en la supervivencia, este suele acompañarse de radioterapia. Se requieren más estudios clínicos aleatorizados para establecer de manera más clara la efectividad y seguridad de estos tratamientos.
Objectives: To report a case of primary breast B-cell non-Hodgkin's lymphoma (PBL) and to conduct a literature review of its diagnosis and treatment. Material and methods: Case report of an 80-year-old female patient who presented to a private referral institution in Mexico, with PBL. She was also diagnosed with primary liver melanoma by means of targeted biopsy and pathology testing. The patient received treatment with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone), quadrantectomy, lymph node dissection and radiotherapy. The PBL showed good response but, because of progression of the second primary tumor, the patient went on to receive palliative care. A review of the literature was conducted in Medline via PubMed, LILACS and Google Scholar. Cohort studies, case reports and case series in patients with PBL that discussed diagnosis, treatment and prognosis of this disease, published in English and Spanish between 2000 and 2022, were included. Results: Overall, 23 titles were identified, of which 17 consisting of case reports and case series met the inclusion criteria. The majority of patients received R-CHOP as chemotherapy regimen, with irradiation as adjunct therapy. Close to 80 % went into complete remission. The most frequent site of recurrence was the central nervous system. Five-year survival was 83.6 % in the included studies. Conclusions: At present, the CHOP regimen, with or without rituximab and usually accompanied by radiotherapy, is the most widely used and the only one that has shown a positive impact on survival. Additional randomized clinical trials are needed in order to gain a clearer insight into the effectiveness and safety of these treatments.

@#<b>Objective</b> To investigate the outcomes and prognostic factors of differentiated thyroid cancer (DTC) with bone metastasis. <b>Methods</b> A retrospective study was conducted on 108 DTC patients with bone metastasis who were treated in the Cancer Hospital of Chinese Academy of Medical Sciences. Kaplan-Meier survival curves were generated. Log-rank test and Cox proportional hazards model were used to screen the prognostic factors. The correlation between treatment and prognosis was analyzed. <b>Results</b> The median overall survival was 70 months. The 5-, 10-, 15-, and 20-year overall survival rates were 54.4%, 24.3%, 9.8%, and 4.3%, respectively. Univariate analysis showed improved prognosis in patients with single bone metastasis, without skeletal-relatedevents (SREs), and without cervical lymph node metastasis (<i>P </i>= 0.003-0.019). Patients who received combined treatments (<i>P</i> < 0.001) or <sup>131</sup>I treatment alone (<i>P</i> = 0.109) showed better prognosis than those without <sup>131</sup>I treatment. Multivariate analysis identified single bone metastases, SREs, and treatmentas independent prognostic factors. <b>Conclusion</b> In DTC patients with bone metastasis, good prognosis is significantly associated with single bone metastases, absence of SREs, and <sup>131</sup>I therapy in combination with other therapeutic approaches.
ABSTRACT
Liver transplantation (LT) is an important treatment of unresectable hepatocellular carcinoma (HCC). However, the prognosis of tumor recurrence remains poor.If patients with a high risk of tumor recurrence after LT can be predicted preoperatively, suitable recipients are screened so that individualized monitoring and treatment protocols may be formulated for high-risk patients.Then better outcomes are obtained.Therefore it is imperative to accurately identify the relevant risk factors and select appropriate parameters for evaluate the risks of tumor recurrence before LT.This review summarized the latest researches of preoperative clinical predictors for recurrent HCC after LT.It was intended to provide references for selecting recipients and a proper management of high-risk patients.
ABSTRACT
@#Introduction: Non-epithelial is a rare type of ovarian cancer but the most common ovarian neoplasm in reproductive age. This study analyzed the correlation of clinical characteristics to disease-free survival (DFS) and 3-year survival in non-epithelial ovarian cancer. Methods: A cohort analysis of medical records of 30 patients with non-epithelial ovarian cancer from 2016 to 2017 at Dr. Soetomo General Academic Hospital. Survival analysis was performed using Kaplan–Meier test, log-rank test, and Cox regression to determine the correlation of characteristics including age, stage, tumor size, tumor residue, histopathology type and chemotherapy status as prognostic factors for recurrence and mortality. Results: DFS was significantly affected by stage (p=0.049), tumor residue (p<0.0001), and chemotherapy (p=0.005). Stage I, no residual disease, and adequate chemotherapy had the highest DFS and mean DFS rates (94.1% and 35.6 months; 95.5% and 35.7 months; 75% and 31.94 months, respectively). Highest recurrence rates were found in patients with unstaged disease (hazard ratio [HR]=10.08), residue >0 cm (HR=23.13), and inadequate chemotherapy (HR=6.55). Three-year survival was significantly affected by stage (p=0.001), tumor residue (p<0.0001), and chemotherapy (p<0.0001). Stage I, no residual disease, and adequate chemotherapy had the highest 3-year survival rate and mean survival time (94.1% and 35.47 months; 95.5% and 35.7 months; 87.5% and 33 months). The highest mortality were found in patients with unstaged disease (HR=19.99), residue >0 cm (HR=11.33), and inadequate chemotherapy (HR=11.71). Conclusion: Stage, tumor residue, and chemotherapy status in patients with non-epithelial ovarian cancer are significant prognostic factors for DFS and 3-year survival.
ABSTRACT
@#Introduction: The clinical signs of COVID-19 include ageusia and anosmia. Anosmia and ageusia haven’t been evaluated as prognostic factors in any prior studies, though. Therefore, the purpose of this review is to assess the effectiveness of ageusia and anosmia as prognostic indicators in COVID-19 patients. Methods: Literature was collected from various databases systematically using the PRISMA until May 25th,2022. The screening process was performed based on inclusion and exclusion criteria, before being analyzed qualitatively. The risk of bias was assessed using Newcastle-Ottawa Quality Assessment Scale converted by AHRQ. Results: Anosmia and ageusia could be used as the indicator for the good prognostic associated with lower mortality, milder trajectory rate, ICU, and hospital admission risk, and shorter length of stay. Anosmia and ageusia have shown high prevalence to predict a prognosis for the COVID-19 infection. Although COVID-19 prognosis also depends on the other lying conditions, patients with anosmia or ageusia had a lower mortality risk due to the lower body mechanism and cell inflammation mechanism toward the viral load that may not lead to the maladaptive cytokine release in response to infection generally called as a cytokine storm. Conclusion: In COVID-19 patients, anosmia and ageusia have been shown to be indicators of a favorable prognosis due to lower disease severity, mortality, risk of ICU and hospital admission, and shorter duration of stay. Therefore, in order to determine the prognosis, it is important to assess the clinical symptoms of the patients.
ABSTRACT
Lung cancer is considered as the leading cause of cancer-related mortality worldwide. Non-small cell lung cancer (NSCLC) accounts for about 85% of primary lung cancer. Owing to the improved utilization of medical technological level and the popularization of health examinations, the detection rate of early-stage NSCLC is gradually increasing. The main treatment modalities for early-stage NSCLC are surgical resection and adjuvant chemotherapy. Platinum-based chemotherapy is recommended as the standard postoperative adjuvant treatment for patients with completely resected stageⅡ-ⅢA NSCLC. However, adjuvant therapy remains a controversial option in stageⅠB NSCLC. This review focuses on postoperative adjuvant therapy such as adjuvant chemotherapy, targeted therapy, and immunotherapy for completely resected stageⅠB NSCLC. Moreover, the biomarkers and prognostic factors of high-risk patients are discussed.
ABSTRACT
Objective:To investigate the surgical efficacy and prognosis influencing factors of hilar cholangiocarcinoma based on multidisciplinary diagnosis and treatment.Methods:The retrospective cohort study was conducted. The clinicopathological data of 91 patients with hilar cholangiocarcinoma who underwent surgery in Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from April 2004 to April 2021 were collected. There were 59 males and 32 females, aged (61±10)years. Patients who were admitted from April 2004 to March 2014 underwent traditional surgical diagnosis and treatment, and patients who were admitted from April 2014 to April 2021 underwent multidisciplinary diagnosis and treatment. Observation indica-tors: (1) surgical situations; (2) postoperative situations; (3) postoperative pathological examina-tions; (4) postoperative prognosis analysis; (5) influencing factors of postoperative prognosis. Follow-up was conducted using telephone interview and outpatient examination. Patients were followed up once every 6 months after surgery to detect survival. The follow-up was up to April 2023. Measure-ment data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Comparison of ordinal data was conducted using the rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. The Kaplan-Meier method was used to draw survival curve and calculate survival rate. The Log-Rank test was used for survival analysis. Univariate and multivariate analyses were conducted using the COX proportional hazard model. Results:(1) Surgical situations. Of the 91 patients, there were 65 cases receiving hemi- or expanded hemi-hepatectomy, 13 cases receiving tri-hepatectomy, 9 cases receiving partial hepatectomy, 4 cases receiving extrahepatic bile duct resection. There were 24 cases receiving combined vein resection and reconstruction, 8 cases receiving combined pancreaticoduodenectomy, 6 cases receiving com-bined hepatic artery resection and reconstruction, including 24 cases receiving extended radical surgery (tri-hepatectomy, hepatic artery resection and reconstruction, hepatopancreaticoduodenec-tomy). The operation time, volume of intraoperative blood loss and intraoperative blood transfusion rate of 91 patients was (590±124)minutes, 800(range, 500?1 200)mL and 75.8%(69/91), respectively. Of the 91 patients, cases receiving extended radical surgery, the volume of intraoperative blood loss were 4, 650(range, 300?1 000)mL in the 31 patients who were admitted from April 2004 to March 2014, versus 20, 875 (range, 500?1 375)mL in the 60 patients who were admitted from April 2014 to April 2021, showing significant differences between them ( χ2=4.39, Z=0.31, P<0.05). (2) Post-operative situations. The postoperative duration of hospital stay and cases with postoperative infectious complications were (27±17)days and 50 in the 91 patients. Cases with abdominal infection, cases with infection of incision, cases with bacteremia and cases with pulmonary infection were 43, 7, 5, 8 in the 91 patients. One patient might have multiple infectious complications. Cases with bile leakage, cases with delayed gastric emptying, cases with chylous leakage, cases with liver failure, cases with pancreatic fistula, cases with intraperitoneal hemorrhage, cases with reoperation, cases dead during the postoperative 90 days were 30, 9, 9, 6, 5, 3, 6, 3 in the 91 patients. Cases with abdominal infection was 10 in the 31 patients who were admitted from April 2004 to March 2014, versus 33 in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( χ2=4.24, P<0.05). Cases dead during the postoperative 90 days was 3 in the 31 patients who were admitted from April 2004 to March 2014, versus 0 in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( P<0.05). (3) Post-operative pathological examinations. Of the 91 patients, cases with Bismuth type as type Ⅰ?Ⅱ, type Ⅲ, type Ⅳ, cases with T staging as Tis stage, T1 stage, T2a?2b stage, T3 stage, T4 stage, cases with N staging as N0 stage, N1 stage, N2 stage, cases with M staging as M0 stage, M1 stage, cases with TNM staging as 0 stage, Ⅰ stage, Ⅱ stage, Ⅲ stage, ⅣA stage, ⅣB stage, cases with R 0 radical resection, cases with R 1 or R 2 resection were 15, 46, 30, 1, 9, 25, 30, 26, 49, 36, 6, 85, 6, 1, 7, 13, 58, 6, 6, 63, 28. Cases with R 0 radical resection, cases with R 1 or R 2 resection were 15, 16 in the 31 patients who were admitted from April 2004 to March 2014, versus 48, 12 in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( χ2=9.59, P<0.05). (4) Postoperative prognosis analysis. Of the 91 patients, 3 cases who died within 90 days after surgery were excluded, and the 5-year overall survival rate and median overall survival time of the rest of 88 cases were 44.7% and 55 months. The 5-year overall survival rate was 33.5% in the 28 patients who were admitted from April 2004 to March 2014, versus 50.4% in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( χ2=5.31, P<0.05). Results of further analysis showed that the corresponding 5-year overall survival rate of cases without lymph node metastasis was 43.8% in the 16 patients who were admitted from April 2004 to March 2014, versus 61.6% in the 31 patients who were admitted from April 2014 to April 2021. There was a significant difference in the 5-year overall survival rate between these patients without lymph node metastasis ( χ2=3.98, P<0.05). The corresponding 5-year overall survival rate of cases with lymph node metastasis was 18.5% in the 12 patients who were admitted from April 2004 to March 2014, versus 37.7% in the 29 patients who were admitted from April 2014 to April 2021. There was no significant difference in the 5-year overall survival rate between these patients with lymph node metastasis ( χ2=2.25, P>0.05). (5) Influencing factors of postoperative prognosis. Results of multivariate analysis showed that poorly differentiated tumor and R 1 or R 2 resection were inde-pendent risk factors influencing prognosis after surgical treatment of hilar cholangiocarcinoma ( hazard ratio=2.62, 2.71, 95% confidence interval as 1.30?5.29, 1.30?5.69, P<0.05). Conclusions:Compared with traditional surgical diagnosis and treatment, treatment of hilar cholangiocarcinoma based on multidisciplinary diagnosis and treatment can expand surgical indications, reduce proportion of dead patients within 90 days after surgery, improve proportation of radical resection and long-term survival rate. Poorly differentiated tumor and R 1 or R 2 resection are independent risk factors influencing prognosis after surgical treatment of hilar cholangiocarcinoma.
ABSTRACT
Objective: To explore the dynamic changes in serum lipid levels and nutritional status during BCMA-CAR-T-cell therapy in patients with refractory or relapsed multiple myeloma (R/R MM) based on LEGEND-2. Methods: The data of patients with R/R MM who underwent BCMA-CAR-T therapy at our hospital between March 30, 2016, and February 6, 2018, were retrospectively collected. Serum lipid levels, controlled nutritional status (CONUT) score, and other clinical indicators at different time points before and after CAR-T-cell infusion were compared and analyzed. The best cut-off value was determined by using the receiver operator characteristic (ROC) curve. The patients were divided into high-CONUT score (>6.5 points, malnutrition group) and low-CONUT score groups (≤6.5 points, good nutrition group), comparing the progression-free survival (PFS) and total survival (OS) of the two groups using Kaplan-Meier survival analysis. Results: Before the infusion of CAR-T-cells, excluding triglycerides (TG), patients' serum lipid levels were lower than normal on average. At 8-14 d after CAR-T-cell infusion, serum albumin (ALB), total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and apolipoprotein A1 (Apo A1) levels dropped to the minimum, whereas CONUT scores reached the maximum. In addition to TG, apolipoprotein B (Apo B) levels increased compared with baseline. After CAR-T-cell therapy, the patients' serum lipid levels significantly increased with well-improved nutritional status. Spearman's related analysis showed that TC, HDL, and ApoA1 levels after CAR-T-cell injection were significantly negatively correlated with the grade of cytokine-release syndrome (CRS) (r=-0.548, P=0.003; r=-0.444, P=0.020; r=-0.589, P=0.001). Furthermore, survival analysis indicated that the CONUT score was unrelated to PFS, and the median OS of patients with R/R MM in the high-CONUT score group was shorter than that in the low-CONUT score group (P=0.046) . Conclusions: During CAR-T-cell therapy, hypolipidemia and poor nutritional status were aggravated, which is possibly related to CRS. The patients' serum lipid levels and nutritional status were significantly improved after CAR-T-cell treatment. The CONUT score affected the median OS in patients treated with CAR-T-cells. Therefore, specific screening and intervention for nutritional status in patients receiving CAR-T-cell therapy are required.

【Objective】 To investigate the clinical characteristics and prognostic factors of small cell carcinoma of bladder (SCCB), and to explore the efficacy of neoadjuvant therapy. 【Methods】 Clinical information of 47 SCCB patients were retrospectively collected, and the clinical and pathological features were compared with those of urothelial carcinoma (UBC). The prognostic factors and efficacy of neoadjuvant therapy were also investigated. 【Results】 SCCB had higher baseline tumor staging, and was more likely to invade the muscle (100%) and metastasize distantly (21.3%). The overall survival was poor (median: 13.1 months, 1-year survival rate: 53.7%, 5-year overall survival rate: 15.4%). Tumor T staging was a risk factor for SCCB, while neoadjuvant therapy was an independent protective factor that significantly reduced the risk of recurrence and metastasis (HR: 0.189, 95%CI: 0.051-0.697, P=0.012) and death (HR: 0.177, 95%CI: 0.045-0.698, P=0.013), and significantly improved disease-free survival and overall survival. In addition, compared with neoadjuvant chemotherapy alone, neoadjuvant chemotherapy combined with immunotherapy could improve the pathological complete response rate. 【Conclusion】 SCCB is highly malignant and prone to metastasis, and has a poor prognosis. Neoadjuvant therapy combined with radical cystectomy is recommended as the first-line treatment.
ABSTRACT
OBJECTIVE@#to analyze the effect of circulating plasma cells(CPC) on the prognosis of patients with multiple myeloma(MM) in the era of new drugs, and to explore the new definition standard of primary plasma cell leukemia(pPCL).@*METHODS@#The clinical data of 321 patients with newly diagnosed MM and 21 patients with pPCL admitted to our hospital from January 2014 to May 2022 were retrospectively analyzed. According to the proportion of CPC in peripheral blood smears, all patients were divided into 4 groups: CPC 0% group(211 cases), CPC 1%-4% group(69 cases), CPC 5%-19% group(41 cases) and CPC≥20% group(21 cases). The clinical features of patients in each group were compared and the prognosis fators was analyzed.@*RESULTS@#The median OS of the four groups were 44.5,21.3,24.6 and 12.8 months, respectively. Among them, 295 patients(86.3%) were treated with new drugs, and the median OS of the four groups were not reached, 26.7, 24.6 and 14.9 months, respectively. As the survival curves of CPC 5%-19% group and CPC≥20% group were similar, the patients were divided into CPC<5% group and CPC≥5% group, the median OS of CPC<5% group was better than that in CPC≥5% (43.5 vs 22.3 months, P<0.001). In addition, the median OS of patients in the CPC 1%-4% group was also significantly lower than that in the CPC 0% group and similar to that in the CPC≥5% group. Multivariate analysis showed that 1%-4% CPC was an independent risk factor for the OS of patients with CPC<5%. The patients with CPC<5% were stratified by R-ISS staging, and the OS of R-ISS stage Ⅰ or stage Ⅱ with 1%-4% CPC was similar to that of R-ISS stage Ⅲ. The newly defined pPCL patients showed increased tumor load and obvious invasive characteristics. Multivariate analysis showed no independent prognostic factors for pPCL, and high-risk cytogenetic abnormalities(HRCA) had no significant effect on the prognosis.@*CONCLUSION@#The validity of IMWG's new pPCL definition standard was verified, and it was found that the survival of MM with 1%-4% CPC also is poor and the prognosis is very close to pPCL. In addition, the newly defined pPCL has unique clinical and biological characteristics.

ABSTRACT Introduction: Tibial shaft fracture is the most common long-bone fracture, and the standard treatment is intramedullary (IM) nail fixation. Regardless of the development of this technique pseudoarthrosis remains prevalent. Objectives: Evaluate the correlation between wedge fragment size and displacement, displacement of the main fragments of the 42B2 type, and pseudoarthrosis incidence. Methods: We retrospectively assessed all patients with 42B2 type fracture treated with IM nailing between January, 2015 and December, 2019. Six radiographic parameters were defined for preoperative radiographs in the anteroposterior (AP) and lateral views. Another six parameters were defined for postoperative radiographs at three, six, and 12 months. The Radiographic Union Score for Tibial Fractures score was used to assess bone healing. Results: Of 355 patients with tibial shaft fractures, 51 were included in the study. There were 41 (82.0%) male patients, with a mean age of 36.7 years, 37 (72.5%) had open fractures, and 28 (54.9%) had associated injuries. After statistical analysis, the factors that correlated significantly with nonunion were wedge height > 18 mm, preoperative translational displacement of the fracture in the AP view > 18 mm, and final distance of the wedge in relation to its original anatomical position after IM nailing > 5 mm. Conclusion: Risk factors for nonunion related to the wedge and42B2 fracture are wedge height > 18 mm, initial translation in the AP view of the fracture > 18 mm, and distance > 5 mm of the wedge from its anatomical position after IM nailing.

RESUMO Introdução: A fratura da diáfise da tíbia é a fratura mais comum dentre os ossos longos, sendo o tratamento padrão a fixação com haste intramedular (HIM). Independentemente do desenvolvimento da técnica cirúrgica, a pseudoartrose continua prevalente. Objetivo: Avaliar a associação entre o tamanho e o desvio da cunha, os desvios dos fragmentos principais do tipo 42B2 e a incidência de pseudoartrose. Métodos: Avaliamos, retrospectivamente, todos os pacientes com fraturas tipo 42B2 tratados com hastes intramedulares entre janeiro de 2015 e dezembro de 2019. Seis parâmetros radiográficos foram definidos para as radiografias pré-operatórias nas incidências anteroposterior (AP) e perfil. Outros seis parâmetros foram definidos para as radiografias pós-operatórias em 3, 6 e 12 meses de acompanhamento pós-operatório. O Escore Radiográfico de União para as Fraturas da Tíbia (RUST) foi o instrumento usado para avaliar a consolidação óssea. Resultados: Dos 355 pacientes com fraturas da diáfise da tíbia, 51 foram incluídos no estudo. Os pacientes incluídos foram 41 (82,0%) do sexo masculino, com idade média de 36,7 anos, 37 (72,5%) com fraturas expostas e 28 (54,9%) com lesões associadas. Após análise estatística, os fatores que se correlacionaram significativamente com a não consolidação foram a altura da cunha > 18 mm, o deslocamento translacional pré-operatório da fratura na incidência AP > 18 mm e a distância final da cunha em relação à sua posição anatômica original após a cravação do MI > 5 mm. Conclusão: Os fatores de risco para a pseudartrose relacionada com a fratura em cunha e42B2 são a altura da cunha > 18 mm, a translação inicial na vista AP da fratura > 18 mm e a distância > 5 mm da cunha em relação à sua posição anatómica após a fixação IM.
