Survival analysis (Kaplan–Meier method). (a) Follow‐up was initiated after surgery for pancreatic cancer. A total of 60 patients (85.7%) completed follow‐up interviews. The median survival time was 21 months. At the end of 1, 2, 3, and 5 years after surgery, survival rates were 84.2%, 38.7%, 18.5%, and 7.7%, respectively. (b) Peripancreatic nerve plexus (PNP) invasion was closely correlated with survival (P = 0.001). Survival at 5 years was significantly greater in the patient group without PNP invasion. (c) Lymphatic vessel (LV) metastasis was closely correlated with survival (P = 0.001). Patients with no LV metastasis had significantly greater survival at 5 years. (d) Peritumor LV invasion (LVI) was correlated with survival (P < 0.001). Patients with no LVI had significantly better survival at 5 years.
