Kaplan-Meier curves: (A) The solid line shows the survival time for patients with primary liver tumors (hepatocellular and cholangiocellular carcinoma); the dashed line illustrates the survival time of patients with liver metastases. The survival time of both groups did not exhibit a significant difference. (B) The Kaplan-Meier survival curves show significantly better survival for patients with fewer than 3 tumors (solid line) when compared with patients with 3 or more tumors (dotted line). (C) Compared to patients with a tumor diameter greater than 3 cm (dashed line), the Kaplan-Meier survival curves show significantly better survival for patients with a short axis diameter less than 3 cm (solid line).
