Survival analysis of primary ccRCC patients (n = 211). (A) Overall survival. Kaplan-Meier survival analysis of primary ccRCC patients (n = 211) after surgical resection with low DUSP-9 expression (n = 117) and high DUSP-9 expression (n = 94). The survival rate for patients in the DUSP-9 low group was significantly lower than that for patients in the DUSP-9 positive group (log-rank test, p<0.001). (B) Pathological stage I-II; (C) Pathological stage III; (D) Pathological stage IV. Statistical analysis of the difference between DUSP-9 high-expressing and low-expressing tumors was compared in the I-II( B), III(C) and IV (D) patient subgroups. The longest follow-up time is 124 months.
