Oncologic Outcomes Following Partial Nephrectomy and Percutaneous Ablation for cT1 Renal Masses复制标题

肾部分切除术和经皮消融治疗cT1肾肿块后的肿瘤学结果

Following Institutional Review Board approval, we identified patients treated with PN, percutaneous radiofrequency ablation (RFA), or percutaneous cryoablation at our institution for sporadic, localized (N0M0), cT1 solid renal mass between 2000 and 2011, as published in 2015. The cT1 renal masses were defined as renal masses ≤7 cm identified on imaging as per the 2016 AJCC cancer staging manual. All renal masses with radiographic evidence of extension beyond the kidney or extension into the renal or segmental veins were excluded from analysis, as were patients with a history of prior RCC or genetic syndromes. A total of 1422 patients were treated with PN (N = 1055), RFA (N = 180), or cryoablation (N = 187) for cT1aN0M0 renal masses, and 376 patients were treated with PN (N = 324) or cryoablation (N = 52) for cT1bN0M0 renal masses. Since the previous analysis, four patients (three PN and one cryoablation) were excluded because of research authorization refusals and one patient was excluded due to previously unrecorded M1 disease at PN. Patient surveillance was generally recommended at 3, 6, 12, 18, and 24 mo, followed by yearly intervals; variance from this protocol was based on pathologic features and clinical health status.
