[A case of unresectable type 4 gastric cancer which has kept a long-term partial response with adjuvant systemic chemotherapy].
A 69-year-old woman was admitted to our hospital with complaint of epigastric discomfort in February 2006. The detailed examination had revealed type 4 advanced gastric cancer. An exploratory laparotomy was performed for the unresectable case due to peritonitis cartinomatoza. Postoperative S-1 monotherapy (100 mg/body, 4 weeks on, 2 weeks off) was started as an outpatient in April 2006. After 3-course, partial response (PR) was observed for the primary lesion by gastrointestinal endoscopy. In April 2007, the regimen was changed to S-1 (100 mg/body, 3 weeks on, 2 weeks off)+CDDP (60 mg/m2, days 8) combined chemotherapy, then the primary lesion showed a slight increase. Thereafter, the regimen was changed to S-1 monotherapy in March 2008, and S-1+CDDP combined therapy in July 2008 again. PR was kept observed for three years successfully after the exploratory laparotomy. A case of type 4 unresectable gastric cancer was reported that the postoperative chemotherapy of S-1 was effective.
