Fig. 2. Disease-free survival after hepatic resection for initially resectable colorectal liver metastasis analyzed by the Kaplan-Meier method. (A) Disease-free survival curve. (B) Disease-free survival according to neoadjuvant chemotherapy (Group Y: Primarily resectable CRLM patients with neoadjuvant chemotherapy, Group N: Primarily resectable CRLM patients without neoadjuvant chemotherapy). (C) Disease-free survival related to number of metastases, analyzed by the adjusted Cox proportional hazard method.
