BAP1 is a good prognostic factor in advanced non-small cell lung cancer
Bibliographic record
Abstract
PURPOSE: Non-small cell lung cancer (NSCLC) is the leading worldwide source of cancer-related deaths. Although some drugs targeting epidermal growth factor receptor (EGFR) mutations have been developed, most advanced NSCLC is still incurable and new targets for anticancer drugs are in demand. BRCA1-associated protein-1 (BAP1) is a component of the ubiquitin proteasome system (UPS). UPS has emerged as a potential target for anticancer drugs. The aim of the present study was to investigate the expression of BAP1 protein in patients with NSCLC. METHODS: BAP1 expression was measured using Western blot analysis in 103 cases patients with advanced NSCLC. RESULTS: Results revealed 49 (47.5%) patients were classified with high expression of BAP1. Squamous cell carcinomas were more likely to be observed in BAP1 high expressers compared with adenocarcinomas (55.8% vs. 32.3%, p = 0.001). High BAP1 expression was associated with no lymph node metastasis (p = 0.002). There was also a significant association between BAP1 expression and histological type (p = 0.014), while expression of BAP1 was not correlated with other clinical or pathological characteristics. Kaplan-Meier survival analysis showed that patients with high BAP1 expression had a longer median survival compared with patients with low BAP1 expression (23.2 vs. 14.7 months, p = 0.021). Multivariate analysis revealed that high BAP1 expression was an independent lower risk for all 103 patients (HR = 0.61, 95% CI 0.32-0.71, p = 0.003). CONCLUSIONS: BAP1 may be a useful prognostic factor of NSCLC patients and potential target for anticancer drugs.

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

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.
