A case of recurrent gallbladder cancer responding to combination chemotherapy of TS-1 and CDDP

摘要

A 76-year-old man suffering from advanced gallbladder cancer after hepato-pancreaticoduodenectomy had cholangitis and serum elevation of CA19-9 2 years and 6 months after the operation. A recurrent tumor had been recognized from the hilar to the surrounding inferior vena cava, and stenosis of jejunum utilized for pancreaticocholedoco-jejunostomy. A bypass operation of jejunum was performed. Combination chemotherapy with TS-1 100 mg/day (3 weeks) and CDDP 30 mg/day (day 1, 8 drip infusion) in 1 course was performed, and a partial response (PR) was noted. Diarrhea of grade III and decreased WBC of grade II were recognized, and were improved. Two courses of the same chemotherapeutic regimen were carried out. Among 5 months, recurrent tumor showed preservation of PR. Into 3 course of chemotherapy, radiation therapy was selected for second opinion. But recurrent tumor was enlarged acutely, and radiation therapy was stopped. He died 15 months after the first detection of chemotherapy. The combination chemotherapy of TS-1 and CDDP seems to be beneficial therapy for advanced gallbladder cancer.
