abstract

  • 494 Background: Targeted txs are the tx of choice in most mRCC pts. However, HDIL2 which may produce durable responses in a small percentage of cases, is still an option in carefully selected pts. While the effect of prior HDIL2 on the outcome of targeted txs in mRCC pts is poorly defined, a recent single center report (Birkhauser FD, Cancer J 2013) revealed an improved disease-specific survival in pts treated with prior HDIL2. We aimed to study the effect of prior HDIL2 tx on outcome of mRCC pts treated with sunitinib. Methods: Records from 302 mRCC pts treated with Su from 2004 to 2013 in 9 centers across 2 countries were retrospectively reviewed. We compared the response rate, progression free survival (PFS), and overall survival (OS), between post HDIL2 pts (n=27) and individually matched tx naive pts (n=27). Progression free survival and overall survival were determined by Cox regression. Results: All pts had prior nephrectomy and clear cell histology. The groups were matched by age (median 61), gend...
