Abstract

The c-met proto-oncogene encodes the receptor for the hepatocyte growth factor/scatter factor (HGF/SF) which induces eel proliferation and motility. We have analysed the genetic alteration involving the c-met locus on chromosome 7q31 using the pMet H polymorphic probe, in tumor and normal DNA from 87 patients with head and neck squamous cell carcinomas (HNSCC). We report the observation of loss of heterozygosity (LOH) at this locus in 23% of informative cases, contrasting with the previously reported 40% LOH detected in breast cancer. Further, gain of genetic material was also observed in 13% of the HNSCCs. The alterations of c-met gene were not significantly associated with standard pronostic features including tumor size and lymph node status. Involvement of the c-met locus in allelic imbalance, either loss or gain of genetic material, is relatively consistent with complex karyotype patterns detected in head and neck squamous cell carcinomas through previous cytogenetic studies.
