Figure 4. — (A) Survival analysis of primary ccRCC patients (n=206). Kaplan-Meier survival analysis of primary ccRCC patients after surgical resection with high FER expression (n=136) and low expression (n=70). The cumulative survival rate for patients in the FER high group was significantly lower than that for patients in the FER-negative group (χ²=8.315; P=0.004). (B) Patients with no regional lymph node involvement (N0) had a better prognosis than those with regional lymph node involvement (N+) (χ²=7.251; P=0.007). (C) Patients with no distant metastasis (M0) had a high cumulative survival rates when compared with patients with metastasis (M1) (χ²=14.214; P<0.001). The longest follow-up time was 120 months. ccRCC, clear cell renal cell carcinoma.
