Seventy-six proved cases of bronchogenic carcinoma developed during an 8-10 year follow-up period among 6,137 older men in the Philadelphia Pulmonary Neoplasm Research Project. Twelve of these men had measurable peripheral tumors, chest roentgenograms read as negative 5 to 7 months before the first roentgenograms on which cancer was recognized, and survival was apparently determined only by the malignant disease. Four cases were resected. The initial size of the cancer ranged from 1.0 to 8.2 cm. in mean diameter; there was an inverse correlation between initial size and survival, whether the tumor was resected or not.

The initial size of a cancer 6 months after a chest roentgenogram read as negative reflects the rate of growth. This was confirmed in 8 cases by an inverse correlation between initial size and doubling time.
