Frequency of Hepatocellular Carcinoma after Direct-acting Antiviral Therapy for Chronic Hepatitis C: A Prospective Follow-up.

BACKGROUND

Chronic hepatitis C (CHC) management has changed tremendously after direct-acting antivirals (DAAs) availability. Sustained virological response (SVR) has improved significantly, but one of the major concerns is the chances of hepatocellular carcinoma (HCC) development after DAAs. The objective of the study is to calculate the frequency of newly diagnosed cases of HCC after antiviral therapy for CHC in Pakistan.

MATERIALS AND METHODS

This prospective, interventional research was conducted from June 2017 to September 2020. All patients after antiviral therapy for CHC were followed with an ultrasound abdomen and α-fetoprotein, six monthly. Multiphasic computed tomography (CT) of the abdomen was performed in suspected cases. For quantitative variables, the mean and standard deviations were calculated, whereas the qualitative variables were analyzed by frequencies and percentages.

RESULTS

Among 180 patients, 110 were men and 70 were women with a mean age of 45.52 ± 11.71 years. One hundred and twenty-six patients were noncirrhotic, 38 had compensated cirrhosis while 16 had decompensated cirrhosis. One hundred and sixty-four (91.11%) patients achieved SVR, of which 22 (12.22%) patients developed new HCC during follow-up. Compensated cirrhosis group had 10 patients, the decompensated group had 12 patients, and the noncirrhotic group had no new HCC cases. Among patients with the new HCC, 12 achieved SVR.

CONCLUSION

The risk of the development of HCC after antiviral treatment is highly significant among patients with liver cirrhosis. So, a strict surveillance strategy should be adopted in every cirrhotic patient following treatment with DAA agents even if they achieve SVR.

CLINICAL SIGNIFICANCE

Chances of developing HCC are still significantly high even after achieving SVR with DAAs in patients with liver cirrhosis.Patients with liver cirrhosis should be under surveillance for HCC even after achieving SVR after DAAs treatment.
