Impact of NAFLD on clinical outcomes in hepatocellular carcinoma treated with sorafenib: An international cohort study.
Bibliographic record
Abstract
289 Background:The incidence of non-alcoholic fatty liver disease (NAFLD)-associated hepatocellular carcinoma (HCC) is increasing. The impact of NAFLD on overall survival (OS), treatment response and toxicity in patients with HCC treated with sorafenib is unknown. We examined the impact of NAFLD on OS and toxicity in an international cohort of patients receiving sorafenib. Methods:Clinical and demographic data were collected from patients consecutively treated at specialist centres in Europe and North America. The impact of NAFLD on OS, sorafenib-specific survival and sorafenib-related toxicity compared to other aetiologies of liver disease using multivariable Cox-proportional hazards and logistic regression modelling was assessed. Results:5201 patients were treated with sorafenib; 183 (3.6%) had NAFLD-associated HCC. NAFLD-associated HCC patients were more likely to be older women(median age 65.8 vs 63.0 years, p < 0.01 and 10.4% vs 2.3%, < 0.01), with a median BMI of 29.4. After controlling for known prognostic factors, no difference in OS in patients with or without NAFLD was observed(adjusted HR 0.94 (95% CI 0.76 -1.16), p = 0.57). NAFLD-associated patients had more advanced stage HCC when they commenced sorafenib (BCLC C/D 70.9% vs 58.9%, p < 0.01) and were more likely to be commenced on a lower starting dose of sorafenib (51.4 vs. 36.4%, p < 0.01). However, there was no difference in sorafenib-specific survival between NAFLD and other aetiologies(HR 0.99, 95% CI (0.85 – 1.16, p=0.92). Adverse events were similar between NAFLD and non-NAFLD HCC groups, including rates of ≥ grade 2 hypertension(6.3 vs. 5.8%, p = 1.00). A lower rate of severe hand foot syndrome was observed in the NAFLD population(3.8 vs. 12.4%, p = 0.03). Conclusions: OS in HCC does not appear to be influenced by the presence of NAFLD. NAFLD-associated HCC derive similar clinical benefit from sorafenib compared to other aetiologies.

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.
