Significance of Repeated Resection for Recurrent Intrahepatic Cholangiocarcinoma

Background/Aims: Management of patients with recurrent intrahepatic cholangiocarcinoma (ICC) following surgical resection is difficult, and surgical resection is rarely indicated. We retrospectively reviewed patients with recurrent intrahepatic cholangiocarcinoma. Methodology: Between April 1998 and March 2007, 57 consecutive patients with ICC underwent surgical resection. Mode of recurrence and treatment of recurrent tumors, especially surgical resection for these tumors, in patients with cancer recurrence were evaluated. Results: 37 (65%) patients experienced tumor recurrence. Out of these patients, 24 underwent some type of cancer-directed therapy, including 9 patients (24%) for whom surgical resection was attempted: the latter included 4 hepatic resections, 2 pulmonary resections, 2 tumor resections, and 1 gastric resection. For 6 patients with recurrent tumor in the liver or the lung, microscopic complete resection was achieved, while incomplete resection was resulted in the remaining 3 patients. No postoperative mortality was encountered. Among patients with complete resection, 3 are alive without disease 32, 39 and 77 months after the second operation, one has lived with disease for 13 months, and 2 died of disease after 22 and 26 months. No significant difference in overall survival was observed between patients undergoing primary and second surgical resections, calculated from the primary and the second operations, respectively. Conclusions: Repeated surgical resection for recurrent ICC can be performed with acceptable morbidity, and affords selected patients a chance for long-term survival.
