Hepatocellular carcinoma prediction beyond year 5 of oral therapy in a large cohort of Caucasian patients with chronic hepatitis B
Bibliographic record
Abstract
•Study conducted in Caucasians with chronic hepatitis B, with or without cirrhosis, after 5 years of entecavir/tenofovir. •Age >50 years, baseline cirrhosis and liver stiffness ≥12 kPa at year 5 were independently associated with increased risk of HCC. •CAGE-B score based on age at year 5 and baseline cirrhosis in relation to LSM at year 5 reliably predicted HCC risk >5 years. •SAGE-B score based only on age and LSM at year 5 was also a reliable predictor of HCC incidence >5 years. Background & Aims Hepatocellular carcinoma (HCC) may develop in patients with chronic hepatitis (CHB) even after 5 years of oral therapy and cannot be easily predicted. We assessed predictors of HCC development and the need for HCC surveillance in this setting. Methods Of 1,951 adult Caucasians with CHB included in the PAGE-B cohort, 1,427 (73%) had completed >5 years of follow-up under therapy without developing HCC by year 5. Median follow-up was 8.4 years from treatment onset. Points-based risk scores were developed to predict HCC risk after year 5. Results In years 5–12, HCC was diagnosed in 33/1,427 (2.3%) patients with cumulative incidences of 2.4%, 3.2% and 3.8% at 8, 10 and 12 years, respectively. Older age or age >50 years, baseline cirrhosis and liver stiffness (LSM) ≥12 kPa at year 5 were independently associated with increased HCC risk. The HCC incidence was lower in non-cirrhotics than cirrhotics at baseline with year-5 LSM <12; among cirrhotics at baseline, it was lower in those with year-5 LSM <12 than ≥12 kPa. CAGE-B score was based on age at year 5 and baseline cirrhosis in relation to LSM at year 5 and SAGE-B score was based only on age and LSM at year 5 (c-index = 0.809–0.814, 0.805–0.806 after bootstrap validation). Both scores offered 100% negative predictive values for HCC development in their low risk groups. Conclusions In Caucasians with CHB, the HCC risk after the first 5 years of antiviral therapy depends on age, baseline cirrhosis status and LSM at year 5. CAGE-B and particularly SAGE-B represent simple and reliable risk scores for HCC prediction and surveillance beyond year 5 of therapy. Lay summary In Caucasians with chronic hepatitis B, the risk of hepatocellular carcinoma after the first 5 years of entecavir or tenofovir therapy depends on age, baseline cirrhosis status and liver stiffness at year 5, which can provide simple and reliable risk scores for hepatocellular carcinoma prediction and surveillance beyond year 5. In patients with cirrhosis at baseline, liver stiffness <12 kPa at year 5 is associated with lower HCC risk, but surveillance may be still required.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
