Large (stage ≥T2b) and locally advanced renal cell carcinoma

Safety and oncological outcomes for large (stage ≥T2b) and locally advanced renal cell carcinoma: comparison between laparoscopic and modified hand-assisted laparoscopic radical nephrectomy: Journal of International Medical Research, Volume 48, Issue 10, October 2020.

ObjectiveTo compare the operative and oncologic outcomes between hand-assisted laparoscopic radical nephrectomy (HALRN) and laparoscopic radical nephrectomy (LRN) for large (stage ≥T2b) and locally advanced renal cell carcinoma.MethodsWe retrospectively collected data from patients who underwent HALRN or LRN for stage ≥T2b renal cell carcinoma from January 2011 to January 2018 in our institution. The patients’ demographics, perioperative parameters, and postoperative follow-up data were compared between the two groups. The survival outcome was estimated using the Kaplan–Meier method.ResultsThe HALRN group comprised 78 patients, and the LRN group comprised 63 patients. The median operative duration was significantly shorter in the HALRN than LRN group. The two groups were equivalent in terms of the incision length, blood loss, complication rate, and duration of hospitalization. In the HALRN and LRN groups, the 5-year overall survival rates were 69.4% and 73.1%, the 5-year cancer-specific survival rates were 80.0% and 83.3%, and the 5-year progression-free survival rates were 66.4% and 74.7%, respectively, with no significant differences.ConclusionsCompared with LRN, HALRN may offer a shorter operative duration and equivalent surgical outcomes without sacrificing oncological efficacy. In addition, HALRN has specific advantages for extremely large and complicated renal tumors.
