摘要

With the demonstration by Cavenee et al. (1) of loss of alleles in famil- ial tumors, validating the Knudson et al. (2) two-hit tumor suppressor hypothesis, it became possible to look for loss of regions of chromosomes in sporadic can- cers of all types. Among the earliest reports of such losses were these report- ing loss of regions of the short arm of chromosome 3 in lung and kidney can- cers (3,4). Since 1987, the losses on this chromosome have been under refine- ment, so that by 1993 it was clear that there were likely to be multiple tumor- suppressor genes on 3p, most pinpointed by homozygous deletions observed in cancer cell lines (5-7) or by familial cancer loci (8,9).
