Kaplan-Meier survival curves according to protein expression of p27^Kip1, Skp2 and Cks1. Cancer-specific survival of patients with RCC were significantly associated with the expression levels of p27^Kip1 (A), Skp2(C), Cks1(E); Recurrence-free survival were significantly associated with the expression levels of p27^Kip1 (B), Skp2(D), Cks1(F).
