ResumoUnexpected high incidence of hepatocellular carcinoma in patients with hepatitis C in the era of DAAs: Too alarming?Journal of HepatologyVol. 65Issue 5PreviewAs a terminator of hepatitis C virus (HCV) infection, sofosbuvir-based direct-acting antiviral agent (DAA) regimens have achieved great success in the eradication of HCV in patients with hepatitis C and related end stage liver diseases [1,2]. Recently, we read with interest the studies by Reig et al. [3] and Kozbial et al. [4] on the surprisingly high incidence of hepatocellular carcinoma (HCC) recurrence and occurrence in patients with advanced liver diseases during interferon (IFN)-free therapy and after sustained virologic response (SVR), respectively. Full-Text PDF Like the investigators from Barcelona [[1]Reig M. Mariño Z. Perelló C. Iñarrairaegui M. Ribeiro A.

Fifteen patients were treated without (AURIC: Austrian ribavirin/interferon-free cohort; ClinicalTrials.gov, NCT02628717) and 4 with ribavirin (RBV). 14 of them achieved sustained virologic response (SVR), 5 relapsed. Before treatment all patients had an imaging method at the discretion of their physician to exclude HCC. The time interval between the last imaging examinations (by ultrasound in 11, each 4 by MRI or CT scan) without evidence of HCC and the start of treatment was 2 months (SD ± 2.1) (see Supplementary Table 1). At baseline, alpha-fetoprotein (AFP) was either within the normal range ( 3 years; &mixed hepatocellular/cholangiocellular carcinoma.BL, baseline; CPS, Child-Pugh Score; CR, complete remission; DCV, daclatasvir; EoT, end of treatment; GT, genotype; HCC, hepatocellular carcinoma; LDV, ledipasvir; n.d., not done; RBV, ribavirin; SMV, simeprevir; SOF, sofosbuvir; 3D, paritaprevir/ombitasvir/dasabuvir.

The patients with HCC can be classified in three groups. Eleven of the 14 cirrhotic patients (#1 to #9, #18, #19) without evidence of HCC in their past history had a SVR 48. Their tumors were relatively small at diagnosis. At EOT, 5 had normal serum AFP levels, and was increased in nine (data missing in 5). At diagnosis of HCC, AFP increased markedly in four, and was stable or normal in seven (AFP in #2, #4, and #9 is missing). The second group consisted of three patients (#10–12) with complete remission after treatment for preexistent HCC (surgical resection in one, radiofrequency ablation in 2). One of them had cirrhosis (#10), and 2 had no evidence of cirrhosis at biopsy. All three had a SVR 48 but developed a HCC during follow up. The third group consisted of 5 patients (#13–17) with relapse at or shortly after EOT. In patient #14, bone metastasis was documented at EOT, and hepatitis C virus (HCV) became detectable again. Further workup showed a HCC. Patient #15 relapsed 1 month after EOT, an ultrasound showed no evidence of a lesion. On retreatment with paritaprevir/ombitasvir/dasabuvir + RBV, AFP levels increased at week 8 of retreatment and HCC was finally diagnosed by magnetic resonance tomography (MRT) one month after EOT. Similar observations were made in patients with complete remission after treatment for HCC treated with IFN-free combination regimens (1) and in Italian patients with cirrhosis without or with previous HCC [[2]Buonfiglioli F, Conti F, Andreone P, Crespi C, Foschi FG, Marco Lenzi, et al. Development of hepatocellular carcinoma in HCV cirrhotic patients treated with direct acting antivirals. Late Breaker Abstract, 51. Annual Meeting of EASL, Barcelona, 2016.Google Scholar]. There is no clear explanation for these observations, but this high number raises the suspicion of a possible relation of HCC with IFN-free DAA therapy. Obviously, patients with advanced liver disease are at high risk for HCC and possibly HCC occurred just by chance in temporal relation to antiviral therapy. Three patients had a HCC in their previous history, but had a documented disease free period of many years and had no evidence for a recurrent HCC by imaging methods. Pretreatment, even the best imaging methods cannot exclude a small HCC with certainty [[3]Park M.S. Kim S. Patel J. Hajdu C.H. Do R.K. Mannelli L. et al.Hepatocellular carcinoma: detection with diffusion-weighted versus contrast-enhanced magnetic resonance imaging in pretransplant patients.Hepatology. 2012; 56: 140-148Crossref PubMed Scopus (94) Google Scholar]. The two-fold increase in HCC rates in Japanese patients treated with IFN-free regimens as compared to IFN/RBV therapy [[4]Toyoda H. Kumada T. Tada T. Changes in patient backgrounds may increase the incidence of HCC after SVR in the era of IFN-free therapy for HCV.Hepatology. 2016; (e-pub)https://doi.org/10.1002/hep.28632Crossref PubMed Scopus (30) Google Scholar] was explained by the higher age and more advanced stage of liver disease. In the present study only 4 of the 19 patients with HCC had Child-Pugh B and one Child-Pugh C. Calculating the frequency of HCC in our patients is difficult. Using the 182 AURIC patients completing 48 weeks of follow-up without developing HCC and the 16 with HCC as denominator, the HCC rate was 8.1% (16/198). By a more conservative estimate (by excluding the 3 patients with the history of HCC) it would be 6.6% overall (13/195) and 5.2% (10/192 in patients with SVR). We hope that the real frequency will be lower when all AURIC patients completed 48 weeks of follow-up. Whatever number is used, it is higher than the estimated 1%/year frequency of HCC in patients with SVR treated with IFN/RBV dual therapy [5van der Meer A.J. Wedemeyer H. Feld J.J. Dufour J.F.

Of the 94 Austrian cirrhotic patients with SVR treated with IFN/RBV 10 developed a HCC within a mean follow-up of 7.8 years (see Fig. 1) [[8]Lu M. Li J. Rupp L.B. Holmberg S.D. Moorman A.C.

Further explanations are that major mechanisms for regeneration are stimulated by curing inflammation, and the changed immunologic environment compared to treatment with IFN-containing treatments leading to growth of precancerous lesions or of small malignant cell clones [[9]Bruix J. Gores G.J. Mazzaferro V. Hepatocellular carcinoma: clinical frontiers and perspectives.Gut. 2014; 63: 844-855Crossref PubMed Scopus (1073) Google Scholar]. Interferon is an immune modulator with anti-proliferative properties. With IFN-free treatments, it has been shown that the rapid disappearance of HCV leads to reconstitution of innate immunity [[10]Serti E. Chepa-Lotrea X. Kim Y.J. Keane M. Fryzek N.

The lack of interferon activation may allow growth of malignant cells. Another factor involved may be miR-122, which plays a central role in suppressing viral replication and controlling hepatocarcinogenesis [13Harouaka D. Engle R.E. Wollenberg K. Diaz G. Tice A.B.

If confirmed, these observations may have an important implication. Patients with cirrhosis should undergo regular HCC screening after achieving SVR. In patients on the orthotopic liver transplantation (OLT) waiting list the risk of developing a HCC could be argument for treating them only after successful transplantation. In contrast, treating non-cirrhotic patients as early as possible may prevent the development of HCC.
