In a review of 1,186 cases of lung cancer found among 7,629 autopsied cases over a 21 year period a total of 82 peripheral cancers related to scars were found, constituting 1% of the autopsied cases and 7% of the lung tumors. 15% of all lung tumors were peripheral (vs. bronchogenic) and the percentage rose from less than 7 in the time period of 1955 to 1960 to a little more than 23 in the 1970 to 1976 time period. 45% of all peripheral lung cancers originated in a scar. Less than 2% of all lung cancers were found associated with scars in the 1955 through 1959 time period. This increased to nearly 16% in the 1970 through 1975 time period. 72% of the scar cancers were adenocarcinomas and 18% were of squamous cell type. The rest were large cell undifferentiated carcinomas and none was oat cell or small cell type. Over three‐quarters of these scar cancers were found in the upper lobes and more than half were related to infarcts. Less than a quarter were related to tuberculosis scars. No relationship was found between smoking habits and scar cancer. Cancer 43:636–642, 1979.
