Partial nephrectomy for renal cell carcinoma provides excellent long-term disease-specific survival, researchers say.
Tobias Klatte, MD, and his colleagues at the David Geffen School of Medicine at the University of California at Los Angeles reviewed data on 321 patients who underwent the procedure. Of these, 232 (55%) had clear cell histology and 218 (68%) had pT stage 1a disease. The mean tumor size was 3.5 cm.
Disease-specific and recurrence-free survival at 15 years were 96% and 87%, respectively. Patients with a positive surgical margin had an increased risk of local recurrence and significantly lower recurrence-free survival.
