摘要

Objective

Cholangiocarcinoma (CCA) has a low survival rate of 5–17%, despite advancements in diagnosis and treatment. Liver function impacts disease prognosis, and the albumin-bilirubin (ALBI) score is a new assessment model for this purpose. While research suggests a correlation between ALBI score, liver failure and mortality in intrahepatic CCA (iCCA), predicting outcomes for extrahepatic CCA (eCCA) is challenging. Our objective was to assess the prognostic role of ALBI grade in predicting overall survival of eCCA patients.

Methods

Patients with diagnosis of eCCA who had visited Firuzgar Hospital from 2015 to 2019 were consecutively included in the study. These individuals had previously undergone Endoscopic Ultrasound-Guided Fine Needle Aspiration (EUS-FNA) or ERCP brush cytology followed by surgery. Exclusion criteria were patients with benign bile duct strictures, prior biliary tract surgery, concurrent liver disease impacting liver tests, inadequate data, or inconsistent monitoring. Clinical data of patients were collected to calculate ALBI score which was subsequently divided into three distinct grades (grade 1: ≤−2.60, grade 2: > −2.60 to ≤ − 1.39, grade 3: >−1.39). Kaplan-Meier analysis and Cox regression model were used to analyze overall survival, 1-, 3- and 5-year survival and parameters affecting patient survival.

Results

In this study, 80 patients with diagnosis of eCCA with a median age of 67 (58.25-74) years (67.5% male) who visited Firuzgar Hospital from 2015 to 2019 were included. The average survival time of patients was 13.9 ± 16.4 months, and the 1-year, 3-year, and 5-year survival rates of patients were 36.6%, 27.1%, and 15.8%, respectively. The results showed that ALBI grade, Aspartate Aminotransferase (AST), white blood cell (WBC) and international normalized ratio (INR) have significant effects on the survival of patients (all P < 0.05). Based on the results of Cox regression, the risk of mortality due to CCA in patients with ALBI grade 3 (HR = 1.87, P = 0.0111), AST > 82.5 (HR = 1.90, P = 0.0091), WBC > 7.70 × 109/L (HR = 2.46, P = 0.0004), and INR > 1.08 (HR = 1.78, P = 0.0202) increases significantly.

Conclusion

We showed that ALBI grade, AST > 82.5 units/L, and INR > 1.08 can be used as predictive factors of survival in cholangiocarcinoma patients.
