Abstract
Recently, the number of reports describing patients with initially unresectable biliary tract cancer (BTC) who underwent resection in the form of conversion surgery is increasing. Gemcitabine plus cisplatin (GC) combination therapy has been reported to significantly prolong the median survival time from 8.1 to 11.7months compared with conventional gemcitabine therapy in patients with unresectable BTC. We report the case of a patient with unresectable BTC who underwent conversion surgery with a partial response to GC combination therapy. A 78-year-old woman was diagnosed with unresectable BTC with invasion of the right hepatic artery by lymph node metastasis and liver metastases. The patient received GC combination therapy. After 6 cycles of chemotherapy, the patient achieved a partial response. The radiological findings revealed a marked shrinkage in the primary lesion and the disappearance of lymph node and liver metastases. Therefore, the patient underwent conversion surgery, including biliary tract resection and regional lymph node dissection. For postoperative follow-up, the patient was monitored without receiving adjuvant chemotherapy. The patient had not exhibited recurrence during the 12-month follow-up period. We report the case of a patient with unresectable BTC who underwent conversion surgery with a partial response to GC combination therapy.
