To evaluate the maternal and fetal outcomes of planned delay in treatment for cervical microinvasive squamous cancer during pregnancy.


A prospective study of pregnant women was done from August 1, 2007 to May 31, 2010. Pregnant women who had not been carried out cervical cytological screening within one year were got thin-prep cytology test (TCT) screening at their initial prenatal visit. Patients with abnormal cytological results were performed colposcopic examination and directed biopsy. Women with cervical microinvasive cancer were followed up every 8 to 12 weeks. If lesion progression were suspected, compared with previous image, repeated biopsy directed by colposcopy should be performed. Once worsening invasive cancer was confirmed, the pregnancy should be terminated timely. All patients should be reevaluated 6 to 12 weeks postpartum with repeated colposcopic examination and biopsy. All mothers were performed cold knife conization (CKC) at 6 to 12 weeks postpartum.


We totally diagnosed 17 cases cervical microinvasive squamous carcinoma during pregnancy. The positive rate is 6.2/10 000 (17/27 230). After informed consent, 15 pregnant women decided to delay treatment until fetal maturation. The mean gestational age of initial diagnosis was (19.3 ± 5.9) weeks. The women were followed up 2 to 4 times during pregnancy. Only 1 patient was verified lesion progression by directed biopsy at 34 weeks and delivered by cesarean section. The progression rate during pregnancy was 1/15. The mean delivered time was (37.1 ± 1.8) weeks (ranged from 34 to 40 weeks). The mean diagnosis-to-delivery interval was (18.4 ± 5.2) weeks. All patients were delivered by cesarean section and all newborns had good outcomes. Finally we confirmed 1 case with cervical cancer stage Ia2, 11 cases with stage Ia1, 3 cases with cervical intraepithelial neoplasia (CIN) III by pathological diagnosis after CKC during 6 to 12 weeks postpartum. All cases were disease free after follow-up ranged from 22 to 48 months.


It is necessary to perform TCT screening for pregnant women who have not been carried out cervical cytology screening within 1 year. If cervical microinvasive squamous cancer were suspected during pregnancy, in order to achieve fetal maturity it is acceptable for the women who desired pregnancy to delay treatment under closely monitoring until postpartum.
