Risk Factors for Short Recurrence-Free Survivals after Resection of PanNET Liver Metastasis: Single Institutional Analysis

#2886

Introduction: Although the treatment of PanNEN has improved survivals with development of pharmacotherapy recently, surgery is the first choice if curative resection is expected to be achieved. However, most of the patients undergo recurrence after resection of the liver metastasis even after curative resection. Therefore, it is important to identify who gains longer RFS by resection.

Aim(s): This study evaluated clinicopathological factors associated with recurrence free survivals after resection of the metastatic NEN in the liver to elucidate a reference guide of the resection.

Materials and methods: Consecutively diagnosed patients with NEN liver metastasis after curative resection at our hospital from January 2000 to July 2019 were evaluated in this study. We analyzed 28 metastatic NEN patients with 32 resections in total with radiologically R0 status. The median follow-up time was 48.1 months
