SMARCA4‐dNSCLC, unlike SMARCA4‐UT, is a type of NSCLC that ranges histologically from well‐differentiated malignant tumors to poorly‐differentiated malignant tumors, including solid adenocarcinomas, mucinous adenocarcinomas, acinar or papillary adenocarcinomas, squamous cell carcinomas, large cell carcinomas, rhabdoid morphology tumors, and malignant tumors containing spindle cell or signet ring cell morphology.2 This evidence concerns the gene SMARCA4 and non-small cell lung carcinoma.
