[A case of long-term survival of unresectable-advanced gastric cancer due to chemotherapy].

The case was a 50s male with chief complaints of body weight loss and nausea. A clinical finding was Stage IV gastric cancer of poorly differentiated adenocarcinoma. We diagnosed it unresectable and started 5-FU+CDDP as the first-line chemotherapy. Partial response (PR) was observed and progression free time was 7 months. After 9 courses of 5-FU+ CDDP, the tumor grew and an oral intake was getting impossible. Gastro-jejunostomy was performed and then started a weekly PTX as the second-line chemotherapy after operation. The response was progressive disease (PD) after 4 courses of weekly PTX. Then we started S-1+CPT-11 as the third-line chemotherapy. We could continue S-1+CPT-11 for 9 courses without a severe adverse effect. Overall survival was 26.2 months.
