Cervical Adenocarcinoma In Situ Diagnosed During Pregnancy

When cervical adenocarcinoma in situ (AIS) is identified in a pregnant patient, and there is no clinical or histologic suspicion of invasive cervical cancer, the clinical approach differs substantially from the standard non-pregnant setting.

Clinical scenario Pregnancy, with no clinical or histologic suspicion of invasive cervical cancer. The absence of concerning invasive features shapes the entire management strategy during the gestational period.

Approach overview

Excisional procedures are deferred during pregnancy. Colposcopic surveillance — with specific modifications to sampling — is carried out through the pregnancy, and a definitive excisional procedure is planned for the postpartum period.

In the absence of a clinical or histologic suspicion of invasive cancer, excisional procedures are not recommended during pregnancy.

Colposcopy omitting endocervical sampling is recommended each trimester, with an excisional procedure performed postpartum. Delaying excision to approximately 6–8 weeks postpartum is preferred, but an excisional procedure as early as 4 weeks postpartum is acceptable (BII).
