The Philadelphia Pulmonary Neoplasm Research Project was begun in 1951, primarily to study the natural history of lung cancer with special emphasis on the chronologic relationship between symptoms and roentgenographic changes. Over the next four years, 6,137 men 45 years of age or older were enrolled. To our knowledge, this is the first such study done on a statistically significant group of older men.

This interim report is concerned with the entire group of 6,137
