目的：研究影响T3N0M0期肾细胞癌患者肿瘤学预后的临床及实验室检查因素。方法：回顾性分析2007年至2012年于北京大学第一医院行手术治疗的T3N0M0肾细胞癌患者的临床资料、实验室检查结果及随访数据。应用Kaplan-Meier法计算生存率，Log-rank方法进行单因素分析，对单因素分析中显著相关的变量采用Cox模型进行多因素生存分析。结果：共182例T3N0M0肾细胞癌患者纳入研究，其中男性患者126例（69.23%），女性患者56例（30.77%）。患者平均年龄为(56.75±12.45)岁，中位随访时间48个月（3~99个月），末次随访时共有50例（27.47%）患者死亡，59例患者（32.42%）复发。患者的5年肿瘤特异性生存率为68.30% （95% CI: 60.16%~75.84%），5年无复发生存率为60.70%（95% CI: 53.16%~68.84%）。多因素分析发现，糖尿病（HR=2.434, 95% CI：1.243~4.769, P=0.010）、术前低白蛋白血症（HR=2.188, 95% CI：1.074~1.074, P=0.031）及贫血（HR=3.320, 95% CI：1.839~5.991, P<0.001）是T3N0M0肾细胞癌患者术后肿瘤特异生存的独立危险因素,更高的Fuhrman分级（HR=2.552, 95% CI：1.433~4.545, P=0.001）、术前贫血（HR=2.535, 95% CI：1.497~4.293, P=0.001）是T3N0M0肾细胞癌患者术后复发的独立危险因素。结论：糖尿病、术前低白蛋白血症、贫血是T3N0M0肾细胞癌患者术后生存的独立危险因素；高Fuhrman分级、贫血是T3N0M0肾细胞癌患者术后复发的独立危险因素。

Objective： To evaluate the impacts of clinical, pathological, and laboratory factors on oncological outcomes of patients with T3N0M0 renal cell carcinoma. Methods: The clinical data, laboratory exam results, and follow-up outcomes of 182 patients with T3N0M0 renal cell carcinoma who underwent nephrectomy from 2007 to 2012 in Peking University First Hospital were retrospectively collected. The 5-year cancer-specific survival and 5-year recurrence-free survival of all the patients were calculated using Kaplan-Meier method, and the statistical significance between the survival curves were compared using the Logrank test. Variables with significant differences in the univariate analysis were subjected to the multivariate analysis by Cox regression model. All the comparisons were conducted using two-tailed test and P<0.05 was considered statistically significant. Results: A total of 182 patients were included in this study. Of all the 182 patients, 126 were male (69.23%) and 56 were female (30.77%). The mean age was (56.75±12.45) years. The median follow-up time was 48 months (3-99 months). At the end of the follow-up, 50 patients (27.47%) died due to the disease after a median of 29.74 months and 59 patients (32.42%) had tumor recurrence after a median of 22.12 months. The 5-year cancer-specific survival of all patients was 68.30% (95% CI: 60.16%-75.84%); the 5-year recurrencefree survival was 60.70% (95% CI: 53.16%-68.84%). In the univariate analysis, diabetes mellitus, tumor invasion status, Fuhrman grade, serum album, serum cholestenone, anemia, and neutrophils percentage were associated with the cancer-specific survival and Fuhrman grade, serum album and anemia were associated with the recurrence-free survival. Variables with significant differences on univariate analysis were included in Cox multivariate regression analysis. Multivariate Logistic regression analysis showed that diabetes mellitus (HR=2.434, 95% CI: 1.243-4.769, P=0.010), hypoalbuminemia (HR=2.188, 95% CI: 1.074-1.074, P=0.031), and anemia (HR=3.320, 95% CI: 1.839-5.991, P<0.001) were independent risk factors significantly associated with cancerspecific survival; and higher Fuhrman grade (HR=2.552, 95% CI: 1.433-4.545, P=0.001), anemia (HR=2.535, 95% CI: 1.497-4.293, P=0.001) were independent factors significantly associated with recurrence-free survival. Conclusion: Diabetes mellitus, hypoalbuminemia, and anemia were independent risk factors significantly associated with cancer-specific survival of T3N0M0 renal cell carcinoma patients; higher Fuhrman grade and anemia were independent risk factors significantly associated with tumor recurrence of T3N0M0 renal cell carcinoma patients.
