HEPATOCELLULAR CARCINOMA AFTER DIRECT ANTIVIRAL AGENTS FOR HEPATITIS C IN PATIENTS WITH DECOMPENSATED CIRRHOSIS

Abstract

Introduction and Objectives: If direct antiviral agents (DAA) are related to the development of HCC is controversial; therefore, exploring risk factors are crucial. We aimed to determine factors related to the development of hepatocellular carcinoma (HCC) in patients with hepatitis c (HCV) and decompensated cirrhosis (DC) treated with DAA. Materials and Methods: A multicenter real-world cohort study including patients with HCV + DC treated with sofosbuvir (SOF) based on regimens free of inhibitors of protease (IPs). Results: 222 patients, 118 (53.2%) were women, mean age 57.2 ±11.5-year-old, 209 (94.1%) achieved sustained virological response (SVR). According to Child-Pugh 44(19.8%) were A with history of any clinical decompensation event, 147(66.2%) B, and 31 (14%) C. After DAA, 134 (60.4%) improve in MELD, 45 (20.3%) had no change, and 43 (19.4%) worse, this worse in MELD was related to non-SVR [SVR 37/209 (17.7%) vs. non-SVR 6/13 (46.2%); OR=2.6, 95%CI:1.4-5.0, p=0.02]. Nineteen (8.6%) developed HCC during the follow-up after therapy with DAA; however, when we compared basal laboratory values between those who developed HCC and those who did not only alfa-fetoprotein (AFP) levels were different (without HCC 14.3 [mean 95%CI: 10.6-18.1] ng/mL vs. HCC 55.7 [mean 95%CI: 28.4-83.0] ng/mL; p 20ng/mL, it is essential to note that patients in this cohort had no any suspicious lesion in ultrasonography (USG) previous to start DAA therapy in their semestral screening as most of the guidelines recommend. AASLD, for example, recommends semestral HCC screening with USG with or without AFP, giving more weight to the imagen study. However, based on our results, we recommend always determining AFP levels as a compliment to USG. Conclusions: In HCV patients with DC treated with DAA and with a negative basal screening USG for suspicious malignant lesions, basal AFP > 20ng/mL are the most critical factor related to the development of HCC and should be determined complementary to the USG study.The authors declare that there is no conflict of interest.
