[A case of advanced gastric cancer with lymphangitis carcinomatosa of the lung, successfully treated with paclitaxel and TS-1].

A 65-year-old man, who had been admitted to another hospital with complaints of severe cough and dyspnea, was transferred to our hospital for the further examination and therapy. The patient was diagnosed with advanced gastric cancer (type-3) with lymphangitis carcinomatosa of the lung. He was treated with combination therapy of 5-FU and cisplatin, and showed a complete response. However, because resistance was seen in the lymphangitis of the lung and the gastric lesion; and a liver metastasis was also seen, we attempted combination therapy with paclitaxel and TS-1. Sixty mg/m2/day of paclitaxel was administered intravenously on day 1 and 8, and TS-1 of 60-80 mg/m2/day was administered orally for 2 weeks followed by one drug-free week. After 2 courses of the combination therapy, the patient achieved a remarkable response in the lymphangitis carcinomatosa of the lung, but a slight response in the liver metastasis and gastric lesion.
