Objectives: Previous reports have indicated that results of the surgical resection of hepatic metastases from gastric carcinoma have been unsatisfactory. We therefore evaluated the results of aggressive surgical resection for hepatic metastases from gastric carcinoma, to identify candidates with a better likelihood of survival.
Methods and results: Twenty-one patients with synchronous or metachronous hepatic metastases from gastric carcinoma underwent hepatic resections. Five patients were still alive, without recurrence, at 10, 41, 46, 117, and 176 months after their hepatic resection. Sixteen patients died of recurrence 5-33 months (mean, 10 months) after hepatic resection. A significant difference in the number of node metastases (solitary or multiple) and in the tumor-free margin of the resection (< 10 mm or > 10 mm) was found between survivors and those who died.
Conclusion: Hepatic resection for hepatic metastases from gastric carcinoma may improve the prognosis in patients with a solitary metastasis if adequate tumor-free margins (> 10 mm) can be obtained.
