Background/Aims: Surveillance for hepatocellular carcinoma (HCC) with ultrasound in high-risk populations is generally believed to improve opportunities for treatment. However, tumors are still missed due to various factors. This study explores success versus failure of HCC surveillance. Methods: This is a retrospective study of 1,125 HCC cases. Categories considered for successful detection were largest tumor ≤3.0 cm, single tumors ≤3.0 cm and ≤2.0 cm, and adherence to Milan criteria. Examined factors were age <60 years, gender, rural residence, body-mass index (BMI), hepatitis infection, smoking, diabetes, hyperlipidemia, cirrhosis, ascites, and Model for End-Stage Liver Disease <10. Results: HCC was found on surveillance in 257 patients with a mean tumor size of 3.17 cm; multiple tumors were seen in 28% of cases, bilateral tumors in 7.4%, and vascular invasion in 3.7%. Surveillance was successful in 61.5% of cases involving a largest tumor ≤3.0 cm, with BMI ≥35 negatively affecting detection (odds ratio [OR] 0.28, P=0.014) and cirrhosis positively affecting detection (OR 2.31, P=0.036). Ultrasound detected 19.1% of single tumors ≤2.0 cm with ascites improving the detection rate (OR 3.89, P=0.001). Finally, adherence to Milan criteria occurred in 75.1% of cases, revealing negative associations with diabetes (OR 0.48, P=0.044 and male gender (OR 0.49, P=0.08). Conclusions: Although surveillance is recommended for HCC, not all surveillance ultrasound are ideal. Tumor detection can depend on gender, BMI, diabetes, cirrhosis, and ascites and is achieved in 19.1-75% of cases depending on the definition of success. Closer follow-up or additional imaging might be necessary for some patient subgroups. (Clin Mol Hepatol 2017;23:239-248)

Aims: The optimal duration of therapy to achieve SVR depends on multiple factors. In a post-hoc analysis of the Phase 3 ION-3 (treatment-naive (TN), non-cirrhotic (NC) patients) 8 week of LDV/SOF data, a viral load (VL) <6M was shown to be the best predictor of SVR. Real world effectiveness (RWE) is often different from Phase III trials and there is a need to understand real-world 8 week regimens in a broader spectrum of patients. Methods: RWE 8 week LDV/SOF data is emerging from multiple single- center and multicenter retrospective and prospective cohorts. In this analysis, the phase-3 ION-3 data is compared with data from several diverse real world populations and one post-marketing investigator sponsored HIV/HCV trial. Patient demographics, characteristics, SVR12 and discontinuation data has been compared. Results: The ION-3 post-hoc analysis reported 123 patients who were TN, NC and VL<6M and treated with 8 weeks of LDV/SOF. Mean age was 52, 22% black, 72% GT1a; the SVR12 was 97% (119/123). The overall SVR12 rate from six diverse real world and post marketing cohorts was also 97% (638/658). There was no significant impact of HCV genotypes or subtypes (GT1a, 1b versus GT4), prior treatment history, presence or absence of cirrhosis, high viral load (HCV VL>6M), or HIV/HCV co-infection. All response rates are detailed in Figure1. Conclusions: LDV/SOF for 8 weeks yielded high SVR rates in ION-3. Analysis of RWE data from several diverse and heterogeneous cohorts from the US & EU show SVR outcomes that were consistent with the ION-3 results and supports the use of 8 weeks LDV/SOF in treatment- naive, non-cirrhotic GT1 patients with a baseline HCV VL <6M and possibly in other populations including HIV/HCV co-infected patients. Discontinuation rates were low despite diverse patients and clinical settings. Data from the TARGET and TRIO cohorts also suggests that the 8-week regimen is underutilized.

Aims: Lengthening treatment with elbasvir/grazoprevir (EBR/ GZR) to 16 weeks and/or adding ribavirin (RBV) is recommended for select patients with HCV GT1 infection. However, realworld data (J Hepatol 2017;66:S295) suggest that utilization of this regimen is low. This study examined the use of 12- and 16- week EBR/GZR ±RBV regimens in different patient subgroups. Methods: Data were collected from providers and specialty pharmacies through Trio Health’s disease management program. Patients (n=442) with HCV GT1 infection who initiated EBR/GZR therapy between Jan 28, 2016 (FDA approval) to Dec 31, 2016 were included. Results: 401 (91%) patients received EBR/GZR for 12 weeks, 12 (3%) received EBR/GZR+RBV for 12 weeks, 11 (2%) received EBR/GZR for 16 weeks, and 18 (4%) received EBR/GZR+RBV for 16 weeks. Possible baseline NS5A resistance was identified in 13/285 patients with GT1a infection: 3 (23%) received EBR/ GZR for 12 weeks, 1 (8%) received EBR/GZR+RBV for 12 weeks, 2 (15%) received EBR/GZR for 16 weeks, and 7 (54%) received EBR/GZR+RBV for 16 weeks. Across all patients, the +RBV subgroup had a higher proportion of treatment-experienced patients (43%, 13/30) than the -RBV group (17%, 69/412); and the 16-week subgroup had a higher proportion of GT1A subtype (93%, 27/29) than the 12-week group (62%, 258/413). Other characteristics including gender, age, baseline viral load, and cirrhosis were similar between regimens and between groups defined by RBV addition or therapy duration. SVR12 results at time of abstract submission were available for 262/442 patients. Overall per protocol (PP) SVR12 was 97% (253/262). Across GT1 subgroups (defined by subtype, prior treatment experience, and fibrosis) that received EBR/GZR for 12 weeks without RBV, the PP SVR12 was ≥94% (TABLE). Conclusions: In real-world practice, EBR/GZR was highly effective, with the majority of patients treated for 12 weeks without RBV. Full SVR12 data will be presented at the conference.
