Abstract

INTRODUCTION: 

Although up to 50-70% of patients with intrahepatic cholangiocarcinoma (ICC) recur following resection, data to predict post-recurrence survival (PRS) and guide treatment of recurrence are limited.

METHODS: 

Patients who underwent resection of ICC between 2000 and 2020 were identified from an international, multi-institutional database. Data on primary disease as well as laboratory and radiologic data on recurrent disease were collected. Factors associated with PRS were examined and a novel scoring system to predict PRS (PRS score) was developed and internally validated.

RESULTS: 

Among 986 individuals who underwent resection for ICC, 588 (59.6%) patients developed recurrence at a median follow up of 20.3 months. Among patients who experienced a recurrence, 97 (16.5%) underwent re-resection/ablation for recurrent ICC; 88 (15.0%) and 403 (68.5%) patients received intra-arterial treatment or systemic chemotherapy/supportive therapy, respectively. Patient American Society of Anesthesiologists (ASA) class > 2 (1 point), primary tumor N1/Nx status (1 point), primary R1 resection margin (1 point), primary tumor G3/G4 grade (1 point), carbohydrate antigen (CA) 19-9 > 37 UI/mL (2 points) at recurrence and carcinoembryonic antigen (CEA) > 5 ng/mL (2 points) at recurrence, as well as recurrent bilateral disease (1 point) and early recurrence (1 point) were included in the PRS score. The PRS score successfully stratified patients relative to PRS and demonstrated strong discriminatory ability (C-index 0.70, 95% confidence interval 0.68-0.72). While a PRS score of 0-3 was associated with a 3-year PRS of 62.5% following resection/ablation for recurrent ICC, a PRS score > 3 was associated with a low 3-year PRS of 35.5% (p = 0.03).

CONCLUSIONS: 

The PRS score demonstrated strong discriminatory ability to predict PRS among patients who had developed recurrence following initial resection of ICC. The PRS score may be a useful tool to guide treatment among patients with recurrent ICC.
