Lung Cancer
Histologic Classification of Non-small Cell Lung Cancer Squamous cell (epidermoid) carcinoma spindle cell variant Adenocarcinoma acinar papillary bronchoalveolar solid tumor with mucin Large cell carcinoma giant cell clear cell Adenosquamous carcinoma Undifferentiated carcinoma
TNM Staging Stage TNM 5-year Survival O Carcinoma in situ 1A TIN0M0 67% 1B T2N0M0 57% IIA T1N1M0 55% IIB T2N1M0 T3N0M0 38% IIIA T3N1M0 T1N2M0 T2-3N2M0 23% IIIB T4N0-2 T1-4N3M0 5% IV T1-4N0-3M1 1% Survival is very heavily dependent upon TNM tumor stage Stages 1A through IIIB are dependent on the T and N classification Stage IV disease is defined by metastatic disease Major distinctions: Stage IIA and stage IIB Stage IIIA and stage IIIB
