We aimed to evaluate the long-term oncological and functional outcomes after robot-assisted partial nephrectomy (RAPN) for renal hilar tumors.
A total of 22 academic hospitals in Japan participated in a prospective, multicenter, single-arm, open-label trial with a 2-year enrollment period. After undergoing RAPN, 105 patients with clinical T1 renal hilar tumors were followed up for 5 years and evaluated. Recurrence-free survival, overall survival, and trends of renal function were set as oncological and functional outcomes.
Five-year overall survival and recurrence-free survival were 98.0% and 89.2%, respectively. Mean estimated glomerular filtration rates (eGFRs) were 69.031 mL/min preoperatively, and were 59.374, 58.334, 58.221, 56.975, and 59.602 mL/min at 1, 2, 3, 4, and 5 years after surgery, respectively. While eGFR was significantly lower than the preoperative one at all points (p < 0.001), eGFRs at 1 and 5 years after surgery did not differ significantly (p = 0.793).
After long-term follow-up, RAPN for clinical T1 renal hilar tumors continues to provide functional and oncological outcomes equivalent to those in the perioperative period.
The study protocol was registered in the Japan Registry of Clinical Trials (jRCT1052190005, UMIN000023968).
我们旨在评估机器人辅助部分肾切除术(RAPN)治疗肾门肿瘤后的长期肿瘤学和功能结局。
日本共有22家学术医院参与了一项前瞻性、多中心、单臂、开放标签试验,入组期为2年。105例临床T1期肾门肿瘤患者接受RAPN治疗后,进行了5年的随访和评估。无复发生存率、总生存率以及肾功能趋势被设定为肿瘤学和功能结局。
5年总生存率和无复发生存率分别为98.0%和89.2%。术前平均估计肾小球滤过率(eGFR)为69.031 mL/min,术后1、2、3、4和5年分别为59.374、58.334、58.221、56.975和59.602 mL/min。虽然各时间点的eGFR均显著低于术前(p < 0.001),但术后1年和5年的eGFR无显著差异(p = 0.793)。
经过长期随访,RAPN治疗临床T1期肾门肿瘤在功能和肿瘤学结局方面仍与围手术期相当。
该研究方案已在日本临床试验注册中心注册(jRCT1052190005,UMIN000023968)。
