Cell of origin markers identify different prognostic subgroups of lung adenocarcinoma
Strong prognostic markers able to stratify lung adenocarcinoma (ADC) patients are lacking. We evaluated whether a six-immunohistochemical markers panel (TTF1, SP-A, Napsin A, MUC5AC, CDX2 and CK5), defining the putative neoplastic “cell of origin”, allows to identify prognostic subgroups among lung ADC. We screened a large cohort of ADC specimens (2003–2013) from Torino Institutional Repository identifying: i) marker positivity by immunohistochemistry ii) main morphological appearance by light microscopy, iii) presence of “hot spot” mutations of candidate genes by Sequenom technology.
