AIM:To determine the role of interferon(IFN)with or withoutribavirin in preventing or delaying hepatocellular carcinoma(HCC)development in patients with hepatitis C virus(HCV)related cirrhosis.Data on the preventive effect of IFN plusribavirin treatment are lacking.METHODS:A total of 101 patients(62 males and 39 females,mean age 55.1±1.4 years)with histologically proven HCVrelated liver cirrhosis plus compatible biochemistry andultrasonography were enrolled in the study.Biochemistryand ultrasonography were performed every 6 mo.Ultrasoundguided liver biopsy was performed on all detected focallesions.Follow-up lasted for 5 years.Cellular proliferation,evaluated by measuring Ag-NOR proteins in hepatocytesnuclei,was expressed as AgNOR-Proliferative index(AgNOR-PI)(cut-off=2.5).Forty-one patients(27 males,14 females)were only followed up after the end of anyearly treatment with IFN-alpha2b(old treatment controlgroup=OTCG).Sixty naive patients were stratified accordingto sex and AgNOR-PI and then randomized in two groups:30 were treated with IFN-alpha2b+ribavirin(treatmentgroup=TG),the remaining were not treated(control group=CG).Nonresponders(NR)or relapsers in the TG receivedfurther IFN/ribavirin treatments after a 6 mo of withdrawal.RESULTS:AgNOR-PI was significantly lowered by IFN(P<0.001).HCC incidence was higher in patients withAgNOR-PI>2.5(26% vs3%,P<0.01).Two NR in the OTCG,none in the TG and 9 patients in the CG developed HCCduring follow-up.The Kaplan-Mayer survival curves showedstatistically significant differences both between OTCG andCG(P<0.004)and between TG and CG(P<0.003).CONCLUSION:IFN/ribavirin treatment associated with re-treatment courses of NR seems to produce the best resultsin terms of HCC prevention.AgNOR-PI is a useful markerof possible HCC development.Azzaroli F,Accogli E,Nigro G,Trerè D,Giovanelli S,MiracoloA,Lodato F,Montagnani M,Tamé M,Colecchia A,Mwangemi C,Festi D,Roda E,Derenzini M,Mazzella G.Interferon plusribavirin and interferon alone in preventing hepatocellularcarcinoma:A prospective study on patients with HCV relatedcirrhosis.World J Gastroenterol 2004;10(21):3099-3102http://www.wjgnet.com/1007-9327/10/3099.asp AIM: To determine the role of interferon (IFN) with or with tribavirin in preventing or delaying hepatocellular carcinoma (HCC) development in patients with hepatitis C virus (HCV) related cirrhosis. Data on the preventive effect of IFN plus ribavirin treatment are lacking. METHODS: A total of 101 patients (62 males and 39 females, mean age 55.1 ± 1.4 years) with histologically proven HCVrelated liver cirrhosis plus compatible biochemistry andultasography were enrolled in the study. Biochemistry and ultrasonography were performed every 6 months. Ultrasoundguided liver biopsy was performed on all detected focalles. Froh-up lasted for 5 years. Cellular proliferation, evaluated by measuring Ag-NOR proteins in hepatocytes nuclei, was expressed as AgNOR-Proliferative index (AgNOR-PI) males, 14 females) were only followed up after the end of any treatment with IFN-alpha2b (old treatment controlgroup = OTCG). Sixty naive patients were stratified according to sex and AgNOR-PI an d then randomized in two groups: 30 were treated with IFN-alpha2b + ribavirin (treatmentgroup = TG), the remaining were not treated (control group = CG) .Nonresponders (NR) or relapsers in the TG receivedfurther IFN / ribavirin treatments after a HPO incidence was higher in patients with AgNOR-PI> 2.5 (26% vs 3%, P <0.01). Two NR in the OTCG, none in the TG and 9 patients in the CG developed HCCduring follow-up. The Kaplan-Mayer survival curves showed statistically significant differences both between OTCG andCG (P <0.004) and between TG and CG (P <0.003) .CONCLUSION: IFN / ribavirin treatment associated with re-treatment courses of NR results to produce the best results in terms of HCC prevention. AgNOR-PI is a useful marker of possible HCC development.
