Steatohepatitic Variant of Hepatocellular Carcinoma: A Focused Review
Bibliographic record
Abstract
The incidence of hepatocellular carcinoma (HCC) has steadily increased over the past three decades and currently ranks as the fifth most common cancer worldwide. Likewise, non-alcoholic fatty liver disease (NAFLD), a known risk factor for the development of HCC, has emerged as the most common liver disease in Western countries. The underlying pathogenesis of NAFLD-related HCC remains unclear. The steatohepatitic variant of HCC (SH-HCC) typically presents in patients with metabolic risk factors and either cirrhotic or non-cirrhotic NAFLD and shares many of the histological features found in non-alcoholic steatohepatitis (NASH). Given their similar morphological features, distinguishing SH-HCC from background fatty liver can be a diagnostic challenge. Immunohistochemical studies to characterize and assist in the diagnosis are relatively limited. Whether the steatotic phenotype of SH-HCC results from the tumor's adaptive response to an environment rich in fatty acids or from an independent pathogenic pathway remains to be seen. This review aims to summarize what is currently known regarding the pathogenesis and clinicopathological features of SH-HCC.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
