Sixty-three non-small cell lung carcinomas (NSCLCs) and 20 small cell lung carcinomas (SCLCs) were examined for loss of heterozygosity (LOH) on chromosome 2. Fifteen highly polymorphic dinucleotide markers spanning both the short and long arms of chromosome 2 were selected for a polymerase chain reaction (PCR)-based fine mapping. They included a DNA marker localized in the homozygously deleted region at 2q33, which we previously identified in an SCLC cell line. LOH on chromosome arm 2q was detected in 23/63 (37%) of NSCLC and 6/20 (30%) of SCLC, while LOH on 2p was observed in 14/56 (25%) and 4/17 (24%), respectively. There were two commonly deleted regions mapped to 2q32-q37 and 2p16-pter, and the homozygously deleted region at 2q33 was in the commonly deleted region on 2q. In NSCLC, the incidence of LOH on 2p and 2q was significantly higher in brain metastases than in primary tumors (P = 0.005 and 0.001, respectively). In addition, LOH on chromosome arm 2q occurred more frequently in moderately/poorly differentiated tumors than in well-differentiated tumors (P = 0.046). These results suggested that inactivation of tumor suppressor genes on chromosome 2 is involved in the phenotypic alterations of NSCLC cells into more aggressive ones.
