[Two cases of recurrent gastric cancer treated by combined chemotherapy of TS-1 and low-dose cis-platinum].
We report 2 patients with recurrent gastric cancer treated by combined chemotherapy of TS-1 and low-dose cis-platinum (TS-1/LCDDP). Who both obtained long-term survival while maintaining good QOL. Case 1: A 60-year-old man underwent total gastrectomy for gastric cancer (pT3, pN2, Stage III B). Three months after surgery, multiple liver metastases were identified, for which TS-1/LCDDP therapy (TS-1 100 mg/body/day, CDDP 10 mg/body/week; 1 course for 4 weeks) was started without hospitalization. After CR was obtained after 4 courses, an additional 4 courses were carried out. At present, 1 year and 11 months have passed since the initial treatment, and CR has been maintained. Regarding adverse events, only grade-1 pigmentation was observed. Case 2: A 65-year-old man with gastric cancer (pT3, pN1, Stage III A) underwent distal gastrectomy. One year after surgery, CT showed both multiple liver and pulmonary metastases. Twelve courses of TS-1/LCDDP therapy have been carried out for 2 years and 4 months. Therapeutic effect was NC, but the patient was able to tolerate the treatments as an outpatient without any subjective symptoms. Leukopenia (grade 2), pigmentation, stomatitis and nausea (grade 1) were observed. Both patients received TS-1/LCDDP therapy as outpatients with good QOL and performance status (0). Recently, chemotherapy for recurrent cancer has been focusing on long-term survival and maintenance of QOL, instead of tumor shrinkage. These results suggest that TS-1/LCDDP treatment is useful as a first-line chemotherapy for patients with recurrent gastric cancer.
