This study investigated the association of neoadjuvant chemotherapy (NAC) with oncologic outcomes in 52 patients with intrahepatic cholangiocarcinoma (ICC) undergoing hepatectomy. The results showed that NAC was independently associated with improved overall survival in ICC patients, but not recurrence-free survival. Additionally, NAC was not associated with major post-operative complications or margin status.
Background: The impact of neoadjuvant chemotherapy (NAC) on overall and recurrence-free survival (OS, RFS) in resectable intrahepatic cholangiocarcinoma (ICC) is poorly characterized. We sought to investigate the association of NAC with oncologic outcomes in ICC. Methods: We identified n = 52 patients with ICC undergoing hepatectomy from 2004 to 2017. Oncologic outcomes were analyzed using Kaplan-Meier and multivariate Cox proportional hazard modeling. Results: The median patient age was 64-years. NAC was administered in ten (19%) patients, most commonly with gemcitabine-cisplatin (n = 8, 80%). Median RFS and OS were 15 months. and 49 months, respectively. Controlling for stage and margins, NAC was independently associated with improved OS (HR 0.16, P = 0.01) but not RFS (HR 0.54, P = 0.27). NAC was not associated with major post-operative complications (P = 0.25) or R1 margins (P = 0.58). Conclusion: NAC in ICC may hold oncologic benefits beyond downstaging borderline resectable disease, such as identifying patients with favorable biology who are more likely to benefit from resection.
