A case of unresectable advanced gastric cancer treated with S-1/low-dose CDDP combination chemotherapy through jejunostomy

A 70-year-old woman with unresectable advanced gastric cancer accompanied by peritoneal dissemination underwent jejunostomy, and was treated with S-1 and low-dose CDDP. One course consisted of S-1 (80 mg/day) via an intestinal fistula tube from days 1 to 14. This was followed by 7 days rest, and CDDP (20 mg/day) was administered by 1-hour continuous intravenous infusion on day 1 and 8. She continued to receive this chemotherapy for a total of 14 courses, followed by 3 courses of a weekly paclitaxel regimen. She died 14 months after surgery. All chemotherapy had been conducted in an outpatient setting. We concluded that the administration of S-1, combined with low-dose CDDP (div) through a jejunostomy, can improve the quality of life (QOL) of a patient who has unresectable advanced gastric and is incapable of oral intake. We report this rare case with a review of the literature.
