RESUMEN
Objective To explore the prognostic value of modified Glasgow prognostic score (mGPS) and risk factors in predicting overall survival (OS) in the castrate-resistant prostate cancer (CRPC) treated with docetaxel-based chemotherapy.Methods We retrospectively analyzed the data of 48 consecutive Chinese patients with CRPC received docetaxel-based chemotherapy in our institution from January 2008 to January 2012.Patients were divided into three groups according to the mGPS:0,1 and 2 score groups,and compare the OS among the three groups.Variables that were influenced the efficacy of chemotherapy were included in the univariate analysis and multivariate model.Survival analysis was performed using Kaplan-Meier curves,and the differences in overall survival rates were assessed using the Logrank test.Results The follow-up was performed until April 2014.There were 48 CRPC patients including mGPS 0 score group 30 cases,mGPS 1 score group 11 cases and mGPS 2 score 7 cases.The median OS was 22,11,9 months,respectively,P＜0.01.Univariate analysis showed that:prechemotherapy baseline total prostate-specific antigen (tPSA),Eastern Cooperative Oncology Group (ECOG) score,the number of chemotherapy cycle,visceral metastasis and PSA response were associated with poor prognosis (P＜0.05).Multivariate analysis showed that:prechemotherapy mGPS 1-2 score,baseline tPSA＞60 μg/L,the number of cycles of chemotherapy≤5,with visceral metastasis and PSA response in patients with CRPC were independent risk factors for prognosis in the CRPC treated with docetaxel-based chemotherapy.Conclusion mGPS is an independent risk factor for prognosis in the CRPC patients treated with docetaxel-based chemotherapy.
RESUMEN
Objective:To analyze the impact of endophytic extent of renal tumor on the perioperative outcomes after partial ne-phrectomy and evaluate the long-term therapeutic effect of early renal cancer. Methods:A retrospective review was performed for 157 patients who underwent partial nephrectomy of T1N0M0 kidney cancer in Tianjin Medical University Cancer Institute and Hospital be-tween January 2011 and December 2013. The patients were classified into two groups according to the distance of the tumor margin to the collective system or renal sinus fat:group A,0.05). The warm ischemia time and operation time were significantly longer in group A than in group B (P=0.001;P=0.033). Postoperative complications occurred in 10 patients. No local tu-mor recurrence or metastasis was observed in the patients during a median follow-up of 18 months. Conclusion:The distance between the tumor margin and the collective system reflects the complexity of partial nephrectomy, which is associated with the warm ischemia time and operation time. Partial nephrectomy is safe and effective. This procedure has low complications and good survival.
