Clinical efficacy of TS-1 combined with cisplatin for advanced cardiac gastric cancer with multiple liver metastases--two case reports
Abstract
Case 1: A 62-year-old man was introduced to our hospital for Type 1 cardiac gastric cancer. On the abdominal CT, there was evidence of multiple liver metastases. The patient was treated with daily oral administration of TS-1 (120 mg/day) for 3 weeks followed by 2 weeks' rest and infusion of CDDP (60 mg/m2) on day 8 as 1 course. After completion of 1 course, partial response in the primary tumor, and complete responses in the liver and lymph node metastases had been assessed, although the primary tumor increased during the 2 months' rest after 4 courses. Case 2: A 67-year-old man was hospitalized for Type 3 cardiac gastric cancer with multiple liver and lymph node metastases. A combination of TS-1 (100 mg/day), and CDDP (60 mg/m2), and TS-1 (80-50 mg/ day) was used. After 2 courses of TS-1/CDDP and 4 courses of TS-1, the primary tumor decreased significantly in size, and complete responses in the liver and lymph node metastases had been assessed, although the primary tumor, liver and lymph node metastases increased after 6 courses of TS-1. The two cases under study suggest that the combination systemic chemotherapy of TS-1 and CDDP is an effective treatment for advanced gastric cancer with multiple liver metastases in terms of its antitumor effect and QOL of the patients.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
