Abstract
Patients [3000] with primary carcinoma of the lung entered in the Armed Forces Central Medical Registry [USA] are reported. Forty-one percent had squamous cell, 28.5% adenocarcinoma, 25.2% small cell/undifferentiated and 4.9% had miscellaneous cell types. When first seen, 71.1% had no organ metastases and 50.6% no lymph node metastases. Overall survival rate was 18.2% at 5 yr and 14.5% at 10 yr. Survival following definitive resection, palliative resection, definitive radiation, palliative radiation and chemotherapy was determined in the presence of mediastinal nodal involvement and in the absence of mediastinal nodal involvement. Where resection for cure could be done, 5 yr survival rates of 48.8% were possible. The factors affecting this improved outlook in the military population are discussed and appear to be related to a ready accessibility of medical care and the necessity, because of global commitments, of establishing an early diagnosis. Cell type exerted some influence on survival, but the major determinant appeared to be the absence of involved nodes at the time of operation.
