Abstract
Background: Lung cancer is the most common type of cancer worldwide with an estimation of 1.82 million new cancer cases diagnosed; and it is the leading cause of cancer-related deaths. Epidermal growth factor receptor (EGFR) is a receptor tyrosine kinase identified as being highly expressed in cancer cells including lung cancers. The aim of the study is to determine the EGFR mutation status in non-small cell lung cancer (NSCLC) patients to investigate the association between the EGFR mutation status and clinicopathological characters of patients. Methods: The tissue samples of the lung cancer patients were collected bronchoscopically. The EGFR mutations of 70 NSCLC patients were determined by the immunohistochemistry (IHC). Results: EGFR mutations were present in 24 cases (34.29%), including 19 (79.13%) cases of exon 19 and five (20.83%) cases of exon 21 mutation. EGFR mutations were frequently associated with adenocarcinoma and non-smoker. Statistically significant association of EGFR mutations with adenocarcinoma subtypes and non-smokers was found (P < 0.05); and no significant association of EGFR mutation with the age of the patient (P = 0.4647) and the stage (P = 0.4578) of the tumor was found. When we compared between these two mutations, no significant association with age (P=0.614) and smoking status (P=0.127) was found in this study. Conclusions: EGFR mutations were significantly associated with female sex, non-smoker and adenocarcinoma subtypes. The analysis of EGFR mutation by the IHC method is a potentially useful tool to guide clinicians for personalized treatment of NSCLC patients of adenocarcinoma subtype.

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 it
