[A case of gastric cancer with multiple bone metastasis that responded to S-1 with low-dose cis-platinum].
We report a patient with multiple bone metastasis who was treated successfully using S-1 and low-dose cis-platinum (CDDP). Metastasis was diagnosed 4 years after distal gastrectomy for early gastric cancer in a woman now 68 years old. Surgery was performed on February 9, 1999. The primary tumor was located in the midportion of the gastric body, and had invaded the submucosa with metastasis to lymph nodes in the area of the lesser curvature. She was discharged from our hospital 24 days after surgery. About 4 years after surgery, she experienced a backache and her CEA and CA19-9 levels had risen to 15.30 ng/mL and 996.5 U/mL, respectively. The results of an imaging examination were suggestive of multiple bone metastasis. Treatment with S-1+CDDP was started with the following regimen: daily oral administration of 100 mg/body/day S-1 for 14 days, followed by a 7-days rest and CDDP 20 mg/body infusion on day 1 and 8. Three months after initiation of therapy, the CEA and CA19-9 levels decreased 2.80 ng/mL and 36.8 U/mL, respectively. No severe adverse effects were observed with this therapy. The combination of S-1 and CDDP can be a good tool for the management of gastric cancer with bone metastasis.
