[Management of cervical intra-epithelial neoplasm during pregnancy].

Approximately 30% of women diagnosed with cervical cancer are in their childbearing years. Prenatal care provides an excellent opportunity for cervical cancer screening. The incidence of abnormal Pap smear has been reported in 5-8% of pregnant women. But we must know that Pap smears have cytologic modifications because of pregnancy. All abnormal smears have to be referred to colposcopic examination. The squamocolumnar junction is visualized in almost 100% of cases. The sensitivity of colposcopy is nearly 87% with complete concordance in 72.6%. Colposcopically directed biopsies have a good correlation with the final diagnosis with very minimal risks for both mother and fetus. The high rate of complications (hemorrhage, abortion, premature labor) and residual lesions in half of cases do not encourage conization during pregnancy. The final treatment is carried out after delivery. The only absolute indication for conization in pregnancy is to rule out microinvasive disease or make the diagnosis of invasive carcinoma when such a diagnosis will alter the timing of delivery but also when there is a no satisfactory colposcopy and a high-grade Pap smear. In these cases conization is performed for diagnostic and not therapeutic purpose. We must be aware of the high rate of loss of follow-up (6-33%).
