Abstract

Background and Aims: We studied the impact of Portal hypertension (PHT) on ascites occurrence and on radiotherapy outcome in cirrhotic patients with hepatocellular carcinoma (HCC). Method: All cirrhotic patients that received radiotherapy for HCC between 2012 and 2022 were included. Portal hypertension-Score was built using univariate analysis with the presence of esophageal varices (EV), platelet count, history of acute variceal bleeding (AVB) and spleen size. Time-to-events data were estimated using Kaplan-Meier method with log-rank and Cox-models. Results: 60 patients were included (female 27%, age 67 years-old, Child-Pugh A 82%, alcoholic/non-alcoholic steatohepatitis/hepatitis C virus 55/40/32%). 38% and 15% presented history of ascites and AVB respectively, 25% had large EV, 53.5% presented PHT score ≥ 5. 92% were BCLC-0/A, median tumor size was 30 mm. At 6 months, ascites incidence was 19% and precluded access to further HCC treatment for all patients with HCC recurrence. All PHT parameters included in the score and PHT score ≥ 5 (hazard ratio (HR) = 14.07, p = 0.01) were associated with ascites occurrence. Transplantation free survival and recurrence free survival at 1 year were 56% and 47% respectively. Albi grade 3 (HR = 3.01; p = 0.04) was independently associated with Transplantation free survival. Conclusion: Radiotherapy should be cautiously performed in patients with PHT score ≥ 5 because of ascites occurrence risk precluding access to further HCC treatments.
