Of the 128 cases of NSCLC, the mRNA expression of EIF4G1 in adenocarcinoma (75/128), squamous carcinoma (42/128), large cell carcinoma (4/128) and adenosquamous carcinoma (3/128) had no statistical difference, but its expression was higher in sarcomatoid carcinoma (4/128). This evidence concerns the gene EIF4G1 and non-small cell lung carcinoma.
