LOH was observed in 14 of 26 (53.8%) heterozygous (informative) patients at APC and 9 of 13 (69.2%) heterozygous patients at MCC. Homozygous deletion of MCC was detected in one patient. Of the 37 patients, 29 were informative at APC or MCC or both; LOH at APC and/or MCC was detected in 68.9% (20/29) of the cases. Ten cases were informative for both genes; LOH at both loci was found in only three of these cases. LOH at the APC and/or MCC was found in both early and advanced stages of oral SCCs. No significant correlation was observed between LOH at the APC and/or MCC locus and the patients' tobacco/betel quid consumption, tumour location. TNM status, or histological differentiation. These results suggest that LOH at the APC and/or MCC may be an early event and may play a role in the pathogenesis of human oral SCCs in Taiwan. |
