Abstract

Background: Recurrence of intrahepatic cholangiocarcinoma (ICC) after liver resection (LR) remains high, and optimal therapy for recurrent ICC is challenging. Herein, we assess the outcomes of patients undergoing repeat resection for recurrent ICC in a large, international multicenter cohort. Patients and methods: Outcomes of adults from six large hepatobiliary centers in North America, Europe, and Asia with recurrent ICC following primary LR between 2001 and 2015 were analyzed. Cox models determined predictors of post-recurrence survival. Results: Of patients undergoing LR for ICC, 499 developed recurrence. The median time to recurrence was 10 months, and 47% were intrahepatic. Overall 3-year post-recurrence survival rate was 28.6%. In total, 121 patients (25%) underwent repeat resection, including 74 (61%) repeat LRs. Surgically treated patients were more likely to have solitary intrahepatic recurrences and significantly prolonged survival compared with those receiving locoregional or systemic therapy alone with a 3-year post-recurrence survival rate of 47%. Independent predictors of post-recurrence death included time to recurrence < 1 year [HR 1.66 (1.32-2.10), p < 0.001], site of recurrence [HR 1.74 (1.28-2.38), p < 0.001], macrovascular invasion [HR 1.43 (1.05-1.95), p = 0.024], and size of recurrence > 3 cm [HR 1.68 (1.24-2.29), p = 0.001]. Repeat resection was independently associated with decreased post-recurrence death [HR 0.58 0.43-0.78), p < 0.001]. Conclusions: Repeat resection for recurrent ICC in select patients can result in extended survival. Thus, challenging the paradigm of offering these patients locoregional or chemo/palliative therapy alone as the mainstay of treatment.
