A case of multiple bone metastases from gastric cancer treated with combination chemotherapy of S-1 and CDDP

摘要

We report a case of multiple bone metastases from gastric cancer treated with combination chemotherapy of S-1 and CDDP. A 54-year-old man underwent distal gastrectomy for gastric cancer (Stage II) in March 2003. Multiple bone metastases complicated with DIC were diagnosed in September 2005. The patient was treated with combination chemotherapy of S-1 and CDDP. S-1 (80 mg/m2/day) was administered for 21 days followed by 14 days rest as one course. CDDP (60 mg/m2) administration was begun 8 days after the start of S-1. After one course of the treatment, DIC was resolved. The abnormal uptake at the bone metastases was found to have decreased by bone scintigraphy. Bone metastases recurred in April 2006. Although combination chemotherapy of S-1 and DOC was administered, the patient died of DIC in August 2006. Combination chemotherapy of S-1 and CDDP is considered effective treatment for prolonging survival in cases of gastric cancer with bone metastases.
