Resection of Hepatic Metastasis of Gastric Cancer

ABSTRACT

PURPOSE: The benefit of surgical resection for hepatic metastasis from gastric cancer still remains unclear. We planned this study to estimate the surgical outcome of hepatic metastasis from gastric cancer. METHODS: Sixteen patients underwent hepatic resections for metastasis from gastric cancer between December 1991 and May 2005. We analyzed 11 patients who had no gross residual tumor after their operations. The clinical and pathological factors were evaluated with the surgical outcomes. RESULTS: Six patients had synchronous metastasis and 5 had metachronous metastasis. The number of hepatic metastases was one in 9 patients, two in 1 patient and four in 1 patient. There was no bilobar metastasis. The extents of the hepatic resections were 3 lobectomies, 4 segmentectomies and 4 wedge resections. There was no operative mortality. There was one postoperative complication, an intra-abdominal abscess, which was cured with percutaneous drainage. The mean survival was 18 months, the median survival was 13 months and the 1-year survival rate was 52.0%. One female patient is still alive 80 months after resection for metachronous hepatic metastasis. There was no statistically significant prognostic factor except for the patients' gender. (p = 0.0378) CONCLUSION: We consider that hepatic resection is a safe and valuable option for the treatment of metastatic gastric cancer.
