[A case of liver metastasis of gastric cancer responding well to TS-1].
We report the case of a 79-year-old female with gastric cancer accompanied by liver metastasis that was successfully treated by TS-1, a novel oral fluoropyrimidine derivative. Abdominal CT scan showed a low-density area in the lateral segment of the liver and lymph node swelling in the right side of the abdominal aorta. One treatment course consisted of 4 weeks of TS-1 administration (100 mg daily) followed by a 2-week break. After 2 courses of this treatment, an abdominal CT scan showed no evidence of liver metastasis and a reduction of lymph nodes metastasis. The serum level of CA19-9 was reduced from 780 U/ml to within a normal range. Grade 1-2 toxicity (nausea and diarrhea) was seen after 2 courses. We conclude that TS-1 may be beneficial in the treatment of the liver metastasis of gastric cancer.
