Abstract

Forty-five primary human lung carcinomas were evaluated for the loss of heterozygosity for genes on the short end of chromosome 11. Of 40 evaluable heterozygous cases, loss of the 11 p genes c-M-ras and insulin was documented in nine cases (22%). The clinical parameters investigated for each patient included the disease stage at presentation, the presence of maetastatic disease in either bronchial or mediastinal lymph nodes, and the presence of positive parietal pleural margins in the surgically resected specimen. There were no differences found with respect to these indicators when patients exhibiting the loss of heterozygosity were compared with those who did not have such genetic loss. In addition, when the clinical courses of the two patient groups were compared, there was no difference in survival. We conclude that the loss of heterozygosity for c-H-ras and insulin on 11p is a common finding in primary non-small cell human lung carcinomas but does not confer a more aggressive phenotype on these tumors. Although this genetic lesion may be important in the initial transformation of the cells to carcinoma, the available data for lung carcinoma are insufficient to prove causality.
