Therapy of local recurrence of renal cell carcinoma

Local recurrence (LR) of renal cell carcinoma (RCC) after nephrectomy is a rare event with a poor prognosis. The clinical outcome of 15 patients with LR after tumor nephrectomy was analyzed retrospectively. Within a mean follow-up of 28 months (1-110 months) the mean time to recurrence (TTLR) was 23 months. Mean time to further tumor progression (TTP) after surgery was 22.2 months (11-32 months), after surgery and adjunctive therapy 6.8 months (3-15 months+) and after chemoimmunotherapy alone 3.6 months (3-6 months). Tumor specific survival (TSS) rate was 47% at 1 year and 33% at 3 years. Mean TSS after surgery was 62.2 months (38-110 months), after resection and adjunctive treatment 26 months (8-74 months) and after chemoimmunotherapy 9.2 months (7-15 months). In conclusion, surgery is recommended for treatment of LR. Additional benefit is not confirmed for any adjuctive therapy.
