Using 12 microsatellite markers, we have studied DNAs from the bronchial lavage of 90 individuals who were referred to an early-lung-cancer clinic in the Northwest of England with suspected lung cancer. Genetic alterations were detected in 15 (35%) of 43 patients with lung cancer but also in 11 (23%) of 47 patients with no cytological or radiological evidence of bronchial neoplasia. No significant differences were found between the referring symptoms in any of the second group of individuals with and without genetic alterations. No correlation was found between smoking exposure and loss of heterozygosity (LOH)/microsatellite alterations (MAs) in the microsatellite markers. On comparing LOH with MAs based on cytology review, we found that the prevalent type of alteration in specimens with cytological evidence of malignancy was LOH; in contrast, the individuals with no cytological evidence of malignancy showed a preponderance of MAs (P = 0.01). Our results indicate that a substantial proportion of cells in the bronchial lavage from suspected lung cancer patients carry identifiable genetic alterations. However, the presence of genetic alterations in the bronchial lavage of individuals with no clinical evidence of lung cancer raises the question whether instability is a phenomenon solely associated with cancer or represents a feature of nonneoplastic diseases. Our results suggest that microsatellite PCR-based assays can be developed as tools for the earlier identification of genetic changes in cells exfoliating in the bronchus.
