The Analysis of High-Risk Molecular Markers for Cervical Cancer Patients under Thirty-Five

OBJECTIVE To explore molecular markers for cervical cancer in female patients below thirty-five years of age, so that the markers may be used to formulate a prognosis and to provide some useful targets for improving therapy. METHODS Pathological data were collected from 64 cervical cancer patients under the age of 35 from June, 1995 to June, 2000 in our institution. The data were retrospectively analyzed as a study group, and compared to data obtained from 90 cervical cancer cases over the age of 35 as controls who underwent treatment during the same time period. Immuno-histochemical and quantified image analyses were conducted to look for differences between the two groups in expression of survivin, p27, CD44v6, MMP-2 and TIMP-2. RESULTS The overall 5-year survival rate (65.6%) of the study group was significantly lower (P<0.05) compared to the control group (84.4%). The expression of survivin, MMP -2 and CD44v6 was much higher in the younger study group compared to the older control group, but TIMP-2 displayed higher expression in the control group (P<0.05). There was no significant difference in p27 expression between the two groups (P>0.05). CONCLUSION Young women patients with cervical cancer have a poorer prognosis compared to old women. Our study reveals that survivin, MMP-2, TIMP-2 and CD44v6 expression have a correlation with shorter 5-year survival. Improvement in the prognosis for young cervical cancer patients can be expected using biomedical therapy which targets these molecular markers.
