ABSTRACT
To study the status of homozygous deletions of MTS1/p16 gene in squamous cell carcinoma of the larynx (LSCC) and to discuss the relations of homozygous deletions to the pathological grade and clinical stage of the tumor,Fifty-nine primary LSCC were examined for homozygous deletions of the MTS1/p16 gene by comparative PCR.Three specimens were eliminated for being incapable of comparison with others.Homozygous deletions of the MTS1/p16 gene were found in 9 of 56 tumors (16.07%).The rates of homozygous deletions of MTS1/p16 gene in well,medially,poorly differentiated tumors were 17.24%(5/29),11.76%(2/17),and 20.00%(2/10) respectively.There had no significant difference in various pathological grades of tumors.Homozygous deletions rates of tumors in stagesⅠ~Ⅱand in stagesⅢ~Ⅳwere 5.41% (2/37) and 36.84%(7/19) respectively.The rate of homozygous deletions in stages Ⅲ~Ⅳtumors was significantly higher than that in stagesⅠ~Ⅱ(P<0.01).Homozygous deletions of the MTS1/p16 gene were correlated well with clinical stages.Our data suggested that homozygous deletions of MTS1/p16 gene might be one of the genetic events in the development of the tumor and might play a role in malignant progression of LSCC.
