  1. NSCLC, non-small cell lung cancer; aSmokers include former and current smoker individuals. bOthers include adenosquamous carcinoma (ADSQ), bronchioloalveolar carcinoma, mucoepidermoid lung tumor, Sarcomatoid carcinoma. cTNM Stages were assessed by the seventh edition of TNM classification criteria. dQualitative assessment of tumor differentiation was based on sum of the architecture score and cytologic atypia score (2 = well differentiated, 3 = moderately differentiated, 4 = poorly differentiated).
