HCC diagnoses were from validated tumor registry report. FIB4 score categories were determined by JoinPoint method. HCC incidence per 100 person-yrs was calculated for each FIB4 category. Results: Of 11,727 patients ≥40 yrs, 381 (3.25%) developed HCC over mean follow up of 2.6 yrs. No HCC reported in persons <40 yrs. The mean age at first HCC diagnosis was 55 yrs in men and 58 yrs in women. HCC incidence varied significantly by FIB4 score, age and sex (Figure) and was higher in men than in women of similar age and FIB4 score. In
men aged 40-49 yrs, HCC risk was elevated when FIB4 score was greater than 3.0, as was FIB4 score >2.0 for men ≥50 yrs. In men, HCC incidence buy Neratinib rose more rapidly with increasing FIB4 scores: for patients aged 50-59 yrs, the rates of change (slopes)
for FIB4 score range 3.0 to 6.0 was 1.00 in men versus 0.47 in women (p=0.04). Combining age and FIB4 score, 80% of men and 20% of women were in groups that experienced annual HCC incidence of 1% or higher. Conclusions: FIB4 score was a strong predictor of HCC incidence among all age groups. For the majority of men, HCC incidence was greater than 1% per year, underscoring the importance of HCC selleck antibody surveillance, especially among those with high FIB4 scores. Figure.

Schmidt BACKGROUND AND AIMS: Cannabis (THC) use has been correlated with liver fibrosis progression in retrospective analyses of mono-infected chronic hepatitis C (HCV) patients, particularly in those with established fibrosis. We characterized the long-term effects of THC use on fibrosis progression in women co-infected with HCV-HIV. METHODS: HCV/HIV co-infected women enrolled between 1994-2002 into the Women’s Inter-agency HIV Study (WIHS), Liothyronine Sodium a prospective, multicenter, cohort of women with or at risk for HIV infection, were included in this analysis. Liver fibrosis was categorized according to APRI scores as mild (<0.5), moderate (0.5-1.5), or severe (≥1.5); women with severe fibrosis at entry into WIHS were excluded. THC and alcohol use were treated as continuous variables and quantified as average exposure over time in study until last follow-up or development of severe fibrosis. Associations between THC use and progression to severe fibrosis were assessed using Cox proportional hazards regression. RESULTS: Among 670 HIV/HCV co-infected women [median follow-up: 5.1 (1.2-10.
