Prognostic value of lymph nodes count on survival of patients with distal cholangiocarcinomas

Figure 1 Kaplan-Meier survival curves of all patients in terms of (A) overall survival and (B) cancer-specific survival. There was no significant difference in terms of overall survival (P = 0.233) and cancer-specific survival (P = 0.141) among the three groups. Kaplan-Meier survival curves of patients with node-negative distal cholangiocarcinoma in terms of (C) overall survival and (D) cancer-specific survival. Patients with four to nine retrieved LNs had a better overall (P = 0.026) and cancer-specific (P = 0.008) survival than patients with one to three retrieved LNs and patients with more than nine retrieved LNs. Kaplan-Meier survival curves of N1 patients in terms of (E) overall survival and (F) cancer-specific survival. There was no significant difference in terms of overall survival (P = 0.053) and cancer-specific survival (P = 0.0564) among the three groups. LNs: Lymph nodes.
