Core Tip

Core Tip: The indication for liver resection (LR) for liver metastases from gastric cancer (LMGC) is still controversial. In the present study, the institutional indications for LR for LMGC are shown in detail. The 5-year overall survival rate was 0.48, and our results of LR for LMGC seemed to be acceptable. Although recurrence might develop after the initial LR, additional surgeries for recurrence clearly prolong survival. Pathological serosal invasion of the primary gastric cancer was an independent predictor of poor prognostic outcomes after the initial LR. Aggressive LR may be indicated for carefully selected patients with LMGC.
