    Abstract: Purposes: To date, most studies about the optimal number of target lesions for enhancement criteria for hepatocellular carcinoma (HCC) have focused on cross-sectional analyses of concordance. We investigated the optimal number of target lesions for European Association for the Study of the Liver (EASL) and modified Response Evaluation Criteria in Solid Tumors (mRECIST) guidelines in predicting overall survival (OS). Experimental Design: We analyzed 254 consecutive treatment-naïve patients with HCC having at least 2 measurable target lesions undergoing transarterial chemoembolization. Kappa values for intermethod agreement of treatment responses were calculated for comparisons between use of maximum of 1, 2, 3, 4, or 5 targets versus use of all target lesions. Prognostic values of radiologic assessments according to number of target lesions for predicting OS were expressed as C-index. Results: By EASL and mRECIST guidelines, κ values between responses assessing the longest 2, 3, 4, or 5 targets and assessing all targets were 0.924, 0.977, 1.000, or 1.000 and 0.907, 0.959, 1.000, or 1.000, respectively, whereas those between responses assessing only one target and assessing all target lesions were 0.723 and 0.666, respectively. C-index when measuring the longest 1, 2, 3, 4, 5, and all targets was similar, ranging from 0.739 to 0.749 for EASL criteria and from 0.750 to 0.759 for mRECIST. From Cox regression analyses, radiologic response from each calculation method showed independently significant effects on OS for both guidelines, regardless of number of target lesions. Conclusions: Prognostic values for predicting OS were similar regardless of number of target lesions. Assessing the 2 largest targets rather than only 1 index lesion could be recommended considering high concordances from cross-sectional analyses. Clin Cancer Res; 19(6); 1503–11. ©2012 AACR.

    Hepatocellular Carcinoma Risk Steadily Persists over Time Despite Long-Term Antiviral Therapy for Hepatitis B: A Multicenter Study

    Abstract: Long-term antiviral therapy (AVT) for chronic hepatitis B (CHB) reduces the risk of hepatocellular carcinoma (HCC). We assessed the temporal trends in the incidence of HCC over time during long-term AVT among Asian patients with CHB. Methods: Patients with CHB receiving entecavir/tenofovir (ETV/TDF) as a first-line antiviral were recruited from four academic hospitals in the Republic of Korea. We compared the incidence of HCC during and after the first 5 years of ETV/TDF treatment. Results: Among 3,156 patients, the median age was 49.6 years and males predominated (62.4%). During the follow-up, 9.0% developed HCC. The annual incidence of HCC per 100 person-years during the first 5 years (n = 1,671) and after the first 5 years (n = 1,485) was statistically similar (1.93% vs. 2.27%, P = 0.347). When the study population was stratified according to HCC prediction model, that is, modified PAGE-B score, the annual incidence of HCC was 0.11% versus 0.39% in the low-risk group ( & lt;8 points), 1.26% versus 1.82% in the intermediate-risk group (9–12 points), and 4.63% versus 5.24% in the high-risk group (≥13 points; all P & gt; 0.05). A Poisson regression analysis indicated that the duration of AVT did not significantly affect the overall trend of the incidence of HCC (adjusted annual incidence rate ratio = 0.85; 95% confidence interval, 0.66–1.11; P = 0.232). Conclusions: Despite long-term AVT, the risk of HCC steadily persists over time among patients with CHB in the Republic of Korea, in whom HBV genotype C2 predominates. Impact: Careful HCC surveillance is still essential.
