[c-myc and c-Ha-ras proto-oncogenes in cervical cancer: prognostic value]

Abstract:
The biological behaviour of invasive carcinoma of the uterine cervix is not always predictable. It is therefore important to establish new biological markers which could be useful in determining a more reliable prognosis. We have analyzed the c-Ha-ras and c-myc proto-oncogenes in a large series (154 cases) of cervical cancers at various clinical stages. Alterations of c-Ha-ras (deletion, mutation) and c-myc (amplification) were frequently observed in cervical cancers and were shown to be associated with tumor progression. Furthermore, c-myc overexpression, when detected in early cervical cancers, provides a means of identifying patients at high risk of early recurrence.
