Abstract | BACKGROUND: METHODS: We reviewed the clinicopathological features and outcome of 107 patients with liver metastases without other non-curative factors from the case records of 5437 gastric cancer patients. These subjects included 34 synchronous cases with tumors present at the time of gastrectomy and 73 metachronous cases with new lesions that appeared after radical gastrectomy. RESULTS:
Hepatectomies were performed in nine synchronous and four metachronous cases that had ≤3 tumors with diameters <3 cm. The overall survival rates after hepatectomy were significantly higher than those in eligible candidates who did not receive hepatectomy despite having comparable metastatic status (synchronous, n = 8, p = 0.009; metachronous, n = 24, p = 0.016). The survival rate of patients who underwent hepatectomy for synchronous metastases was not inferior to that of patients who underwent hepatectomy for metachronous metastases. The median disease-free interval in metachronous cases was significantly shorter in patients who did not undergo resection than those who underwent resection. However, multivariate analyses revealed that hepatectomy was the only significant (p = 0.001) prognostic factor whereas DFI was not. CONCLUSIONS:
Hepatectomy for ≤3 metastatic tumors with diameters <3 cm offered superior survival compared with non-surgical treatment even for metastases detected synchronously or within a short period after radical gastrectomy.
