WCE 2019: Local Regional Recurrence of Renal Cell Carcinoma after Robotic Partial Nephrectom

Abu Dhabi, United Arab Emirates (UroToday.com) Mr. Ethan Wajswol began by introducing the reason for studying robotic partial nephrectomy (RPN). RPN has been gaining popularity in the last few years as a reliable way of performing nephrostomy sparing surgery (NSS). NSS is indicated for the treatment of renal cell carcinoma (RCC). However, the incidence of local recurrence for RPN in the treatment of RCC has not been studied extensively. Mr. Wajswol and his colleagues tried to determine the incidence of local-regional recurrence of RCC in patients who have undergone RPN. They defined local recurrence, as recurrence in the partial nephrectomy bed or the surrounding operative field. They retrospectively analyzed all patients at a single, tertiary center who underwent RPN between 2011 and 2019. They found176 patients with a mean age of 63 years and a mean follow-up of 74 weeks. 94.5% of patients had stage T1a or T1b tumors. Only 2 of these 176 patients developed local-regional recurrence, yielding a 1.1% incidence.

In conclusion, Mr. Wajswol and his colleagues found that the rate of local-regional recurrence is quite low in the setting of RPN for the treatment of RCC. Robotic partial nephrectomy is comparable to open and laparoscopic with respect to local-regional recurrence rates ranging from 1.2% to 9%. The recurrence rate that Mr. Wajswol’s institution experienced was close to those reported in the literature.
