[A case of recurrent gallbladder cancer responding to low-dose 5-FU and CDDP therapy]

We treated a patient with a postoperative local recurrence of gallbladder cancer who showed a long-term response to low-dose 5-fluorouracil (5-FU) and cisplatin (CDDP) therapy. A 60-year-old woman was diagnosed with advanced gallbladder cancer, for which she underwent an extended cholecystectomy, bile duct resection and a partial resection of the duodenum in March 2000. The pathological diagnosis was well differentiated tubular adenocarcinoma of si, ly1, v1, hinf2, binf2, n0. Eight months later, she presented with cholangitis and obstructive jaundice due to a local recurrence of the gallbladder cancer and her serum CA19-9 level had increased to 1,991.6 U/ml. The biliary obstruction was treated by PTCD and a subsequent self-expanding metallic stent. In addition, she was also placed on combined chemotherapy with low-dose 5-FU and CDDP. Her serum CA19-9 level thereafter gradually decreased, so that after eight months it was within the normal range, and the recurrent tumor at the hepatic hilus was also observed to have decreased in size on the CT scan. As of this writing she has undergone eight courses of low-dose 5-FU and CDDP therapy over about a year and has been able to maintain a good quality of life without any severe adverse effects.
