A Case of Successful Treatment of Metachronous Liver Metastasis from Gastric Cancer with Hepatectomy
Abstract
A 77-year-old man was found to have advanced gastric cancer and underwent total gastrectomy (pT4aN2H0P0M0, Stage ⅢB). Two years after gastrectomy, we found an elevated tumor marker level, and a liver metastasis appeared in segment 5 (20 mm in diameter). He was treated with S-1/CDDP combination chemotherapy. After 2 courses of chemotherapy, the tumor marker level kept rising and a CT scan detected a progressive tumor. S-1/irinotecan combination chemotherapy was administered as second-line chemotherapy. After 6 courses of chemotherapy, the size of the liver metastasis was reduced and the tumor marker level normalized. Because lymph node metastasis or peritoneal recurrence was observed, a partial resection of the liver (S5) was performed. After the operation, he was treated with S-1 chemotherapy again for 1 year and has had no recurrence.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
