Overall survival by type of response on first evaluation (after 2 cycles of sunitinib treatment). Median OS for patients with progressive disease (PD) = 178 days (n = 9), for stable disease (SD) = 657 days (n = 11) and for partial response (PR) = 763 (n = 19). There is no statistical difference between SD and PR patients (p = 0.6883 with log-rank test) but there was a statistical significant difference between the PD and PR group (p < 0.0001, log-rank test) or between the PD and SD group (p = 0.0008).
