Abstract:
Objective To investigate the impact of portal hypertention with hypersplenism of different severity and splenectomy on prognosis of hepatocellular carcinoma (HCC).
Methods We retrospectively analyzed the clinical data of 403 patients with HCC who met the Milan criteria and received radical treatment in Tianjin Third Central Hospital from January 2008 to January 2018. Cox proportional risk regression analysis was performed for parameters such as platelet levels (PLT), albumin-bilirubin (ALBI) grade, aspartate aminotransferase-to-platelet ratio index (APRI), and post-sinusoidal resistance (PSR). HCC patients with severe hypersplenism were assigned into two groups according to treatment method radical treatment for HCC alone and radical treatment for HCC plus splenectomy. Clinical data were compared, and the two groups were evaluated using the Kaplan-Meier survival analysis method.
Results Univariate and multivariate analyses showed that PLT was an independent risk factor for overall survival (OS) and disease-free survival (DFS) in patients with HCC. OS curves differed significantly with different PLT among patients with HCC (P=0.013). Furthermore, parameters of portal hypertension in cirrhosis, such as PSR, APRI, and ALBI grade, were risk factors for HCC prognosis. The degree of portal hypertension and hypersplenism, liver function, and tumor-node-metastasis stage did not differ between the two groups (P> 0.05). Survival analysis showed significantly longer OS in the radical treatment plus splenectomy group (P=0.025). Following were the 1-, 3-, and 5- year survival rates: radical treatment alone group 100%, 98.2%, and 68.5% and radical treatment plus splenectomy group. 97.1%, 79.4%, and 56.8%, respectively. DFS did not differ between the two groups (P=0.326).
Conclusions Clinical parameters, such as PLT, PSR, APRI, and ALBI grade, are important prognostic factors in HCC patients with portal hypertension and hypersplenism. Radical treatment for HCC plus splenectomy can improve OS in HCC patients within the Milan criteria with severe hypersplenism.
