[A case of gastric cancer with multiple liver metastases resistant to TS-1 responding to chemotherapy with paclitaxel plus doxifluridine].

A 74-year-old man was revealed to have type 3 gastric cancer with synchronous multiple liver metastases. Despite treatment with TS-1 (120 mg/body), an increase in tumor size was demonstrated by computer tomography and endoscopy. We tried a course of a combination chemotherapy consisting of paclitaxel (PTX) plus doxifluridine (5'-DFUR ) to reduce the tumor. 5'-DFUR (600 mg/m(2)) was administered day 1 to 14 followed by 7 days'rest as one course. PTX (80 mg/m(2)) was infused on days 1 and 8. After 5 courses, the tumor markers decreased markedly, and computer tomography and endoscopy revealed remarkable tumor reduction which was thought to show a partial response. After 13 courses we discontinued this chemotherapy, so increase of the tumor marker was remarkable. This case suggests that PTX/5'-DFUR protocol is effective for clinical management of gastric cancer resistant to TS-1.
