Abstract:
PURPOSE: Frequent deletion of 3p in numerous cancer including lung cancer suggests the presence of tumor suppressor gene. 3p has been analysed by RFLP and PCR-LOH of microsatellite locus. In this study, we observed the deletion of 3p in Korean NSCLC by PCR-LOH of 4 microsatellite loci and investigated the clinical significance. Method : 62 surgically rejected NSCLC DNA and normal lung DNA have been analysed by PCR-LOH at three dinucleotide[D3S1228 (3p14.1-14.3), D3S1067 (3p14.3-21.1), D3S1029 (3p21.1-21.3)] and one tetranucleotide[D3S1537 (Sp 22-24.2)] repeat microsatellite loci. RESULTS: Among 59 informative cases, 3p deletion by PCR-LOH at four microsatellite loci was found in 31 patients (52.5%). 3p deletion were found in 55% of squamous cell lung cancer and 47% of adenocarcinoma patients. No significant difference has been found in clinical parameters such as staging, smoking and survival according to the status of 3p deletion. CONCLUSION: Deletions in 3p have played an important role in Korean NSCLC though no clinical significance was detected.
