Pattern of progression in advanced hepatocellular carcinoma treated with ramucirumab.

BACKGROUND & AIMS: Radiological progression patterns to first-line sorafenib have been associated with post-progression and overall survival in advanced hepatocellular carcinoma, but these associations remain unknown for therapies in second- and later-line settings. This post hoc analysis of REACH and REACH-2 examined outcomes by radiological progression patterns in the second-line setting of patients with advanced hepatocellular carcinoma treated with ramucirumab or placebo. METHODS: Patients with advanced hepatocellular carcinoma, Child-Pugh A and Eastern Cooperative Oncology Group Performance Status 0 or 1 with prior sorafenib were randomized to receive ramucirumab 8mg/kg or placebo every 2 weeks. Among 625 patients with ≥1 progression pattern (new extrahepatic lesion [including new macrovascular invasion], new intrahepatic lesion, extrahepatic growth or intrahepatic growth), data were analysed by trial and for pooled individual patient data for REACH-2 and REACH (alpha-fetoprotein ≥400 ng/mL). Cox models evaluated prognostic implications of progression patterns on overall and post-progression survival. RESULTS: Post-progression survival was worse among those with new extrahepatic lesions in REACH (HR 2.33, 95% CI 1.51-3.60), REACH-2 (HR 1.49, 95% CI 0.72-3.08) and the pooled population (HR 1.75, 95% CI 1.12-2.74) compared to other progression patterns. Overall survival was also significantly reduced in those with new extrahepatic lesions across studies. Ramucirumab provided an overall survival benefit across progression patterns, including patients with new extrahepatic lesions (HR 0.56, 95% CI 0.39-0.80) in the pooled population. CONCLUSIONS: The emergence of new extrahepatic lesions in the second-line setting is a poor prognostic factor for post-progression survival. The benefit of ramucirumab for overall survival was consistent across progression patterns.

Ramucirumab in elderly patients with hepatocellular carcinoma and elevated alpha-fetoprotein after sorafenib in REACH and REACH-2.

BACKGROUND & AIMS: Limited data on treatment of elderly patients with hepatocellular carcinoma (HCC) increase the unmet need. REACH and REACH-2 were global phase III studies of ramucirumab in patients with HCC after prior sorafenib, where patients with alpha-fetoprotein (AFP) ≥400 ng/mL showed an overall ssurvival (OS) benefit for ramucirumab. These post-hoc analyses examined efficacy and safety of ramucirumab in patients with HCC and baseline AFP ≥ 400 ng/mL by three prespecified age subgroups (<65, ≥65 to <75 and ≥75 years). METHODS: Individual patient data were pooled from REACH (baseline AFP ≥400 ng/mL) and REACH-2. Kaplan-Meier and Cox proportional hazards regression methods (stratified by study) assessed OS, progression-free survival (PFS), time to progression (TTP) and patient-reported outcomes (Functional Hepatobiliary System Index-8 [FHSI-8] score). RESULTS: A total of 542 patients (<65 years: n = 302; ≥65 to <75 years: n = 160; ≥75 years: n = 80) showed similar baseline characteristics between ramucirumab and placebo. Older subgroups had higher hepatitis C and steatohepatitis incidences, and lower AFP levels, than the <65 years subgroup. Ramucirumab prolonged OS in patients <65 years (hazard ratio [HR], 0.753; 95% CI 0.581-0.975), ≥65 to <75 years (0.602; 0.419-0.866) and ≥75 years (0.709; 0.420-1.199), PFS and TTP irrespective of age. Ramucirumab showed similar overall safety profiles across subgroups, with a consistent median relative dose intensity ≥97.8%. A trend towards a delay in symptom deterioration in FHSI-8 with ramucirumab was observed in all subgroups. CONCLUSIONS: In this post-hoc analysis, ramucirumab showed a survival benefit across age subgroups with a tolerable safety profile, supporting its use in advanced HCC with elevated AFP, irrespective of age, including ≥75 years.

Liver Cancer Disparities in New York City: A Neighborhood View of Risk and Harm Reduction Factors.

INTRODUCTION: Liver cancer is the fastest increasing cancer in the United States and is one of the leading causes of cancer-related death in New York City (NYC), with wide disparities among neighborhoods. The purpose of this cross-sectional study was to describe liver cancer incidence by neighborhood and examine its association with risk factors. This information can inform preventive and treatment interventions. MATERIALS AND METHODS: Publicly available data were collected on adult NYC residents (n = 6,407,022). Age-adjusted data on liver and intrahepatic bile duct cancer came from the New York State Cancer Registry (1) (2007-2011 average annual incidence); and the NYC Vital Statistics Bureau (2015, mortality). Data on liver cancer risk factors (2012-2015) were sourced from the New York City Department of Health and Mental Hygiene: (1) Community Health Survey, (2) A1C registry, and (3) NYC Health Department Hepatitis surveillance data. They included prevalence of obesity, diabetes, diabetic control, alcohol-related hospitalizations or emergency department visits, hepatitis B and C rates, hepatitis B vaccine coverage, and injecting drug use. RESULTS: Liver cancer incidence in NYC was strongly associated with neighborhood poverty after adjusting for race/ethnicity (ß = 0.0217, p = 0.013); and with infection risk scores (ß = 0.0389, 95% CI = 0.0088-0.069, p = 0.011), particularly in the poorest neighborhoods (ß = 0.1207, 95% CI = 0.0147-0.2267, p = 0.026). Some neighborhoods with high hepatitis rates do not have a proportionate number of hepatitis prevention services. CONCLUSION: High liver cancer incidence is strongly associated with infection risk factors in NYC. There are gaps in hepatitis prevention services like syringe exchange and vaccination that should be addressed. The role of alcohol and metabolic risk factors on liver cancer in NYC warrants further study.

Presentation and outcome of hepatocellular carcinoma in HIV-infected patients: a U.S.-Canadian multicenter study.

BACKGROUND/AIMS: HIV-infected patients now live longer and often have complications of liver disease, especially with hepatitis B or C virus coinfection. Limited data are available on those with hepatocellular carcinoma (HCC). METHODS: A retrospective analysis from 1992 to 2005 in 6 centers identified 63 HIV-infected HCC patients. Controls were 226 consecutive HIV-negative HCC patients from four sites. RESULTS: HIV-positive patients were younger than controls (52 vs. 64 years, p<0.001), more commonly had chronic hepatitis B or C (97% vs. 73%, p<0.001), were more frequently symptomatic (51% vs. 38%, p=0.048), had a higher median alfa-fetoprotein level (227 vs. 51 ng/ml, p=0.005), but a similar mean Child-Turcotte-Pugh score (7.0 vs. 7.5, p=0.05) and HCC staging score (Barcelona-Clínic-Liver-Cancer stages C+D in 50% vs. 58%, p=0.24). HCC developed faster in HIV/HCV-coinfected than in HCV-monoinfected patients (mean, 26 vs. 34 years after HCV infection, p=0.002). HIV-positive patients received proven therapy more often (48% vs. 31%, p=0.017), but median survival was similar (6.9 vs. 7.5 months, p=0.44). Independent factors predicting survival were symptomatic presentation (hazard ratio [HR], 0.437; p<0.001), any proven therapy (HR, 2.19; p<0.001), diagnosis after 01-Jan-2002 (HR, 1.52; p=0.010), Barcelona-Clínic-Liver-Cancer stages C+D (HR, 0.491; p<0.001), AST/ALT >or= 2.00 (HR, 0.597; p=0.001), AFP >or= 400 ng/mL (HR, 0.55, p=0.003), and platelets >or= 100,000/mm3 (HR, 0.651; p=0.012), but not HIV-serostatus (p=0.19). In HIV-infected patients without HCC therapy (n=33), median survival was longer with undetectable HIV RNA (<400 copies/mL) than with HIV viremia (6.5 vs. 2.6 months, p=0.013). CONCLUSIONS: HIV-positive HCC patients are younger and more frequently symptomatic and infected with HCV or HBV than HIV-negative patients. Tumor staging and survival are similar. In untreated patients, undetectable HIV RNA independently predicts better survival.
