A total of 62 patients with cT1a renal masses treated between January 2005 and October 2014 were identified from a retrospective cohort. Patients with biopsy confirmed Tla RCC and a follow up period > 48 months were included in this analysis. Local recurrence, metastasis, survival rate and change in glomerular filtration rate (GFR) were analyzed.
The mean (range) follow-up for the laparoscopic RFA was 54.2 (26-97) months. The respective mean tumor size was 2.14 (+ 0.66) cm. The GFR was not significantly different at early follow up, but there was significant difference at the last follow up. There were no local recurrences, metastasis and disease-specific deaths during the entire follow-up period. The 5-year overall survival was 98%, cancer-specific survival was 100%, and recurrence-free survival was 100%.
This data showed that laparoscopic RFA for cTla renal masses has similar oncological and functional outcomes when compared to surgical treatment, but also to active surveillance. Longer follow-up time is required to truly understand the outcomes of this modality and its effects on clinical outcomes.
