[Successful management with S-1 of recurrent gastric cancer after adjuvant chemotherapy with paclitaxel/UFT].
We report here two cases of recurrent gastric cancer after post operative adjuvant chemotherapy, in which S-1 has been effective to control the recurrence and provided long-term survival. Case 1: A 75-year-old male presented with malaise. Endoscopy showed an advanced gastric cancer. He underwent total gastrectomy with lymph adenectomy and received adjuvant chemotherapy with 3 courses of weekly paclitaxel and 6 months of UFT. An abdominal tumor developed with elevation of tumor markers 1 year and 2 months after surgery. After 5 courses of S-1(100mg/day), the tumor resolved and a complete response(CR)was obtained with decline of the markers for 2 years. Case 2: A 62-year-old male presented with abdominal pain. Endoscopy showed an advanced gastric cancer. He underwent distal gastrectomy with lymph adenectomy. Peritonitis carcinomatosa developed with ascites though adjuvant chemotherapy with UFT had been continued for 6 months after paclitaxel. After 10 courses of S-1(100 mg/day), ascites disappeared with decline of the markers. He has been well without any sign of recurrence or elevation of tumor markers for 2 years. Differences in the 5-fluorouracil concentration of UFT and that of S-1 may explain the effectiveness of S-1 for recurrence of gastric cancer after adjuvant chemotherapy with UFT.
