Cytogenetic analysis has been carried out on 8 early passage cell lines derived from 8 untreated human oral squamous cell carcinomas. Clonal aberrations were detected in the karyotypes of each cell line. A high frequency of breakpoints were noted on chromosomes 1, 7, 8, 9, 11, and X. An isochromosome 8 was present in 6 out of 8 cell lines; isochromosome 9 (3 cell lines) and isochromosome 11 (1 cell line) were also found. In 4 out of 8 cell lines the X chromosome harboured breakpoints, a novel finding in oral squamous cell carcinomas. Breakpoints were common on chromosome 1, with 1p12–p13 most frequently involved. Tandem duplication of 11q13–q23, which contains a number of growth regulatory genes, was also noted in 2 cases. We correlate the sites of proto‐oncogenes and other growth control genes with chromosomal breakpoints and suggest that several of these may play a role in the pathogenesis of oral cancer. © 1993 Wiley‐Liss, Inc.
