Abstract

Background: Portal hypertension (PH), which is closely associated with the severity of liver cirrhosis, has been suggested as a contraindication of liver resection for hepatocellular carcinoma (HCC). We aimed to explore the role of a potential player, histologic severity of liver cirrhosis, in affecting surgical outcomes of the patients with both HCC and PH. Methods: A total of 374 HCC patients with PH underwent resection for HCC were retrospectively reviewed. By using the Laennec staging system, the patients were divided into two groups: the mild-moderate cirrhosis (MMC) group and the severe cirrhosis (SC) group. Propensity score matching (PSM) was conducted at a 1:1 ratio between the two groups, and 89 patients were matched for each group. Short-term and long-term outcomes were compared between two groups before and after PSM. Results: The overall morbidity and 30-days mortality were significantly higher in the SC group than the MCC group (52.9% vs. 30.1%, P < 0.001 and 6.9% vs. 0.7%, P = 0.002). Severe cirrhosis was identified as an independent predictor of postoperative liver-related complications. Patients with MMC exhibited better 5-year overall survival (39.9% vs. 16.9%, P < 0.001) and disease-free survival (10.5% vs. 4.4%, P < 0.001) than those with SC. Multivariate analysis indicated that severe cirrhosis was significantly associated with lower disease-free survival and overall survival. These results were further confirmed in the PSM cohort. Conclusions: Histologic severity of liver cirrhosis determines the surgical outcomes of patients with both HCC and PH, and PH is not an absolute contraindication of liver resection.
