[A remarkably improved multimetastatic gastric cancer with the use of TS-1 and CDDP].

: A 62-year-old male presented to our hospital with jaundice. On the abdominal ultrasound and abdominal CT, there was evidence of multiple, massive liver metastases with dilatation of intrahepatic bile ducts, thickened wall of the stomach from the body to the antrum, direct invasion to the pancreas, multiple lymph node metastases, and ascites. We believed it was Stage IV and too far advanced for surgery. Therefore, ST-1 60 mg bid was started, and CDDP 50 mg was infused in the seventh week. On the follow-up CT and ultrasound three months later, the thickening of the gastric wall and the lymph node metastasis had improved and the border between the stomach and the pancreas had become clearer. The liver metastases seen on both lobes had decreased significantly both in size and number. The dilatation of the intrahepatic bile ducts disappeared, and the liver function normalized. No side effects were evident during the treatment with the medications.
