LOH and MSI of Fragile Histidine Triad Gene in laryngeal and hypopharyngeal carcinoma / 中国耳鼻咽喉头颈外科

ABSTRACT

0.05).⑥ The incidence of MSI at D3S1234,D3S4103,D3S1300 in recurring cases was 83.33 %,but the ratio of MSI inprimary cases was 30.77 %,the former was remarkablyhigher than the latter(P=0.004).CONCLUSION ①Microsatellite analysis showed that both LOH andMSI of FHIT gene existed in laryngeal carcinoma andhypopharyngeal carcinoma,the former was morecommon.② FHIT gene participates the developmenof laryngeal carcinoma and hypopharyngeal carcinoma and may be one of the candidate tumor suppressor genes.③ MSI of FHIT gene may be correlated with recurrence of laryngeal and hypopharyngeal carcinoma.
