title: Oncogene expression in cervical cancer.
abstract: Significant advances have been made toward the understanding of the initiation and progression of cervical dysplasia and neoplasia at the molecular level. To date, this has not translated into improvements in diagnosis or treatment although it is a realistic expectation that this will occur. Significant variation in the proportion of tissue specimens that exhibit genetic alterations is striking. This may be attributed to different methods of analysis, different methods of tissue fixation, which influence antigen preservation, and the analysis of small numbers of samples per report, which introduces the possibility of sampling error. In spite of the variation among published reports, it is clear that several genetic alterations occur in preneoplastic and early-stage invasive cervical neoplasms. It remains to be determined which alterations of genetic structure or expression contribute to tumor initiation. The prognostic applicability of oncogene mutations is a particularly interesting area of investigation that is the closest to clinical application, although additional research involving larger numbers of patients is critical. The development of convenient methods of tissue fixation that preserve the myc oncoprotein, the synthesis of specific antibodies that provide consistent results, and the application of computer-assisted image analysis to quantitate results will be particularly important in this regard.
