Abstract

The c-myc and c-fos proto-oncogenes have several putative functions, including regulation of cell growth. In many neoplasms c-myc overexpression has been linked to poor prognosis. In order to study the role of c-myc and c-fos expression on the tumorigenesis, and the metastatic spread of osteosarcoma, frozen and paraffin-embedded tissue 38 primary osteosarcoma and 10 lung metastases were analyzed. The mRNA analysis was performed by quantitative reverse transcription-polymerase chain reaction and in situ hybridization. The protein expression was studied by Western blot analysis and immunohistochemistry. C-myc and c-fos were found overexpressed in a high percentage of the relapsed tumors and of the metastases, and overexpression of both oncogenes in the same tumor was strongly correlated to the development of metastases (p <0.05), as 6 of the 7 primary tumors overexpressing both the oncogenes gave metastases. In conclusion, both c-myc and c-fos are involved in the growth and spread of osteosarcoma and a synchronous overexpression of both oncogenes is highly significant for a metastatic potential of a primary tumor.
