[Oncogene expression in malignant head and neck neoplasia].

Cellular oncogenes may acquire transforming properties and take part in induction or progression of tumors. In the present study we have examined the expression of c-met, c-ras and c-myc in some head and neck carcinomas. In 3 tumors we have found an elevated expression of the c-met oncoprotein, in 2 tumours of the c-myc one. These data suggest that oncogenes could participate in the development of some head and neck cancers.
