BACKGROUND: Few prognostic factors have been proposed for patients with locally advanced renal cell carcinoma (RCC). This study aimed to investigate the possible predictive factors for disease-free survival (DFS) after curative surgery for RCC stage T3 or higher. METHODS: Patients with locally advanced RCC who underwent cure-intended partial or radical nephrectomy, with or without tumor thrombectomy, at our institution from April 1, 2005 to October 31, 2013 were retrospectively reviewed. Those undergoing cytoreductive nephrectomy were excluded. Preoperative data, including surgical and pathologic characteristics, were assessed for correlation with DFS. Chi-square tests, univariate and multivariate Cox regression analysis, and Kaplan-Meier survival curve analyses were performed to determine potential predictive factors. A p value less than 0.05 was considered statistically significant. RESULTS: A total of 159 patients were included for analysis. The mean duration of follow-up was 37.9 months, and 119 (74.8%) patients remained disease-free during follow-up. Disease recurrence was found in 40 (25.2%) patients, and pathologic T stage, capsule penetration, Fuhrman grade, thrombocytosis, renal vein thrombosis, and elevated serum alkaline phosphatase, platelet/lymphocyte ratio, and γ-glutamyl transpeptidase levels were significantly associated with disease recurrence on univariate analysis. On multivariate analysis, Fuhrman grade 3 or 4 (HR = 5.70, p = 0.0003, 95% CI = 2.23-14.56) showed significant associations with DFS. CONCLUSION: In patients with locally advanced RCC, Fuhrman grade was associated with worse DFS after curative surgery. Urologists should closely monitor patients with high Fuhrman grades.
背景:目前仅有少数预后因素被提出用于局部进展性肾细胞癌(RCC)患者。本研究旨在探讨根治性肾部分或根治性切除术治疗 T3 期或更高分期 RCC 患者无病生存(DFS)的可能预测因素。
方法:回顾性分析 2005 年 4 月 1 日至 2013 年 10 月 31 日在我院接受根治性部分或根治性肾切除术(伴或不伴肿瘤血栓切除术)的局部进展性 RCC 患者。排除行减瘤性肾切除术的患者。评估术前数据(包括手术和病理特征)与 DFS 的相关性。采用卡方检验、单因素和多因素 Cox 回归分析以及 Kaplan-Meier 生存曲线分析来确定潜在的预测因素。p 值<0.05 为差异有统计学意义。
结果:共纳入 159 例患者进行分析。中位随访时间为 37.9 个月,119 例(74.8%)患者在随访期间无疾病复发。40 例(25.2%)患者出现疾病复发,单因素分析显示病理 T 分期、包膜侵犯、Fuhrman 分级、血小板增多、肾静脉血栓形成、碱性磷酸酶、血小板/淋巴细胞比值、γ-谷氨酰转肽酶水平升高与疾病复发显著相关。多因素分析显示,Fuhrman 分级 3 或 4 级(HR=5.70,p=0.0003,95%CI=2.23-14.56)与 DFS 显著相关。
结论:在局部进展性 RCC 患者中,Fuhrman 分级与根治性手术后的DFS 较差相关。泌尿科医生应密切监测 Fuhrman 分级较高的患者。
