The six most prominent regions, according to the multinomial model, that discriminate NSCLC from SCLC are located at chromosome arm 1p (e.g., MYCL1), 3p (e.g., FHIT), 9p (e.g., CDKN2A), 16q, 19p (e.g., STK11), and chromosome 22. This evidence concerns the gene STK11 and non-small cell lung carcinoma.
