摘要

Propósito Se intentó determinar la incidencia, hallazgos patológicos, factores pronósticos y resultados clínicos para pacientes con CCR papilar clínicamente localizado. Métodos Demográfico, Se recopilaron hallazgos clínicos y patológicos en todos los pacientes con CCRP sometidos a cirugía en cuatro centros médicos académicos. El punto final primario fue la supervivencia específica del cáncer (CSS). La supervivencia sin recaída (RFS) y la supervivencia general (OS) fueron puntos finales secundarios. Kaplan- Se obtuvieron estimaciones de Meier y se usaron modelos de regresión de riesgos proporcionales de Cox para evaluar predictores de mortalidad y recaída. Resultados Identificamos 626 CCPR, de los cuales 373 (60por ciento) fueron del tipo 1 y 253 (40 por ciento) fueron del tipo 2, con tres cuartas partes de todos los tumores siendo pT1. En comparación con los pacientes con tipo 1, aquellos con tipo 2 eran mayores (edad media: 63 frente a 61; (AU)


Purpose We aimed to determine incidence, pathologic fndings, prognostic factors and clinical outcomes for patients with clinically localized papillary RCC. Methods Demographic, clinical and pathologic fndings were collected on all patients with PRCC undergoing sur-gery at four academic medical centers. The primary end-point was cancer-specifc survival (CSS). Relapse-free survival (RFS) and overall survival (OS) were secondary endpoints. Kaplan­ Meier estimates were obtained, and Cox proportional hazard regression models were used to assess predictors of mortality and relapse. Results We identifed 626 PRCC, of which 373 (60 pertcent) were type 1 and 253 (40 pertcent) were type 2, with three-quar-ters of all tumors being pT1. Compared to patients with type 1, those with type 2 were older (mean age: 63 vs 61; (AU)

摘要

Purpose To report the outcomes of patients with pathologic T4 UTUC and investigate the potential impact of peri-operative chemotherapy combined with radical nephroureterectomy (RNU) and regional lymph node dissection (LND) on oncologic outcomes. Materials and Methods Patients with pathologic T4 UTUC were identified from the cohort of 1464 patients treated with RNU at 13 academic centers between 1987 and 2007. Oncologic outcomes were stratified according to utilization of perioperative systemic chemotherapy and regional LND as an adjunct to RNU. Results The study included 69 patients, 42 males (61%) with median age 73 (range 43-98). Median follow-up was 17 months (range: 6-88). Lymphovascular invasion was found in 47 (68%) and regional lymph node metastases were found in 31 (45%). Peri-operative chemotherapy was utilized in 29 (42%) patients. Patients treated with peri-operative chemotherapy and RNU with LND demonstrated superior oncologic outcomes compared to those not treated by chemotherapy and/or LND during RNU (3Y-DFS: 35% vs. 10%; P = 0.02 and 3Y-CSS: 28% vs. 14%; P = 0.08). In multivariate Cox regression analysis, administration of peri-operative chemotherapy and utilization of LND during RNU was associated with lower probability of recurrence (HR: 0.4, P = 0.01), and cancer specific mortality (HR: 0.5, P = 0.06). Conclusions Pathological T4 UTUC is associated with poor prognosis. Peri-operative chemotherapy combined with aggressive surgery, including lymph node dissection, may improve oncological outcomes. Our findings support the use of aggressive multimodal treatment in patients with advanced UTUC. .
