Glasgow Prognostic Score Predicts Survival and Recurrence Pattern in Patients With Hepatocellular Carcinoma After Hepatectomy

Background/aim: The prognostic significance of the Glasgow Prognostic Score (GPS) on outcomes of liver resection for hepatocellular carcinoma (HCC) remains unclear; the aim of the study was to assess its significance.

Patients and methods: A total of 480 patients with HCC who underwent liver resection with curative intent at the Yokohama City University Hospital and Medical Center were enrolled in the study. Patients were classified into three groups: GPS-0, C-reactive protein (CRP) ≤1.0 mg/dl serum albumin ≥3.5 g/dl; GPS-1, CRP >1.0 mg/dl or serum albumin <3.5 g/dl; and GPS-2, CRP >1.0 mg/dl, serum albumin <3.5 g/dl. Prognostic factors for overall survival (OS) and disease-free survival (DFS) were analyzed retrospectively. The recurrence pattern was also investigated using GPS.

Results: Of the 480 patients, 382 (79.6%), 81 (16.9%), and 17 (3.5%) were assigned to GPS-0, GPS-1, and GPS-2, respectively. Elevated GPS, indocyanine green retention rate at 15 min, and protein induced by vitamin K antagonist-II (PIVKA-II) were significantly associated with a poor OS. Elevated GPS, alpha-fetoprotein, and PIVKA-II were significantly associated with a poor DFS by multivariate analysis. The number of patients with liver-only recurrence in GPS-0, GPS-1, and GPS-2 was 179 (86.1%), 40 (78.4%), and 9 (69.2%), respectively. The number of patients with four or more intrahepatic metastases in the GPS-0, GPS-1, and GPS-2 groups, was 33 (17.9%), 11 (27.5%), and 8 (88.9%), respectively. The number of patients with four or more intrahepatic metastases in the GPS-2 group was significantly higher (p<0.001).

Conclusion: Preoperative GPS is a useful predictor of OS and recurrence pattern after liver resection with a curative intent for HCC.
