Aneuploidy of chromosome 7 can be detected in invasive lung cancer and associated premalignant lesions of the lung by fluorescence in situ hybridisation

Lung Cancer. 2000 Jun;28(3):225-35. doi: 10.1016/s0169-5002(00)00097-0.


In the present study the chromosomal status of seven invasive non small cell lung cancer specimens and associated premalignant lesions was investigated. By fluorescence in situ hybridisation (FISH) with centromere specific probes, an increase in the percentage of aneuploid cells from pre-invasive to invasive lesions could be demonstrated (mean 8.5 and 59%, respectively, for chromosome 7). Furthermore, mean chromosome copy numbers were higher in invasive carcinomas as compared to premalignant lesions, indicating polyploidization during tumor development. Increasing evidence suggests that aberrations of chromosome 7 occur early in the development of lung cancer. Whether these aberrations can be used as a biomarker for future neoplastic progression remains to be determined.
