OBJECTIVE: The incidence of abnormal cervical cytology in pregnancy is similar to that reported for non-pregnant women. Furthermore, 1% of pregnant women annually screened for cervical cancer will be diagnosed with cervical intraepithelial neoplasia (CIN) of various degrees. For this reason, Pap smear should be performed in the first trimester of pregnancy. The persistence of HR-HPV infection is related to the development of CIN. However, the relationship between CIN and HR-HPV infection during pregnancy and postpartum can hardly be found. The aim of this work was to assess the proper management of abnormal cytology during and after pregnancy evaluating regression rate, persistence rate and risk of progression and the predictive role of HPV molecular tests.
PATIENTS AND METHODS: Patients with abnormal cervical cytology were followed-up using colposcopy and colposcopy-directed biopsies every 12 weeks. Molecular tests were performed at the moment of the cytological diagnosis. Patients not treated in pregnancy were re-evaluated with cytology, colposcopy, biopsies, HPV-DNA test and HPV-mRNA test for a final diagnosis 8 weeks postpartum. Women with a persistent CIN 2-3 lesion at this follow-up check, underwent an excisional procedure by LEEP and then re-evaluated every 6 months for a year.
RESULTS: HPV-DNA test showed a sensitivity of 90.5% and a negative predictive value of 96.4%. Specificity and positive predictive values were 67.9% and 43.2%, respectively. For HPV-mRNA test, a sensitivity of 76.2% and a NPV of 93.9% were found; specificity and PPV were 98.7% and 94.1% respectively.
CONCLUSIONS: An observational management based on the use of molecular test and particularly HPV-mRNA test for its higher specificity, is a reasonable possibility in the follow-up of CIN2/3 lesions during pregnancy.Free PDF Download
