title: Microsatellite alterations in non-small cell lung cancer.
abstract: Genetic alterations at 12 dinucleotide repeat loci located on human chromosomes 2, 3, 12, and 17 have been analyzed in non-small cell lung cancer from Thai patients. Seventeen out of 30 cases (57%) harbored the microsatellite alterations. Of the 30 cases, 19 patients had a history of tobacco smoking, of whom 14 (74%) were in the group with microsatellite alterations, whereas 3 out of 11 non-smokers (26%) had these alterations. The frequency of microsatellite alterations among smokers was significantly higher than it was in non-smokers (P = 0.01 Fisher's exact test; odds ratio; 7.47).
