    Abstract:
    We constructed a detailed deletion map of the short arm of chromosome 3 (3p) for 55 lung cancer cases by using 17 restriction fragment length polymorphism (RFLP) probes. Initially, we examined 40 small cell lung cancer (SCLC) cases and found three regions of deletion at 3p25-26, 3p21.3 and 3p14-cen, suggesting the possibility of at least three different tumor-suppressor genes on 3p. In order to obtain more detailed deletion area, and to compare the pattern of 3p deletion, we also examined 15 non-small cell lung cancer (NSCLC) cases. Compared to NSCLC cases, most of SCLC cases have widespread deletion on 3p, suggesting multiple tumor-suppressor genes on 3p may be inactivated in this type of cancer. In 3p21.3 area, minimum overlapping area of deletion lays between two probes which are close to each other. These data will be useful to isolate the putative tumor-suppressor genes located on the chromosome 3p.
