Management of cervical intraepithelial neoplasia during pregnancy: a simplified and cost-effective approach.

Journal of lower genital tract disease·2015

Conservative treatment for cervical intraepithelial neoplasia (CIN) with inadequate colposcopy is safe. Patients with CIN 1-2 and negative endocervical curettage can avoid cone biopsy, preventing unnecessary procedures.

Area of Science:

  • Gynecology
  • Oncology
  • Pathology

Background:

  • Cervical intraepithelial neoplasia (CIN) requires careful management.
  • Inadequate colposcopy poses challenges in diagnosis and treatment planning.
  • Cone biopsy is a standard but invasive procedure for CIN management.

Purpose of the Study:

  • To evaluate the safety and feasibility of conservative treatment for patients with CIN and inadequate colposcopy.
  • To identify criteria for selecting patients who can safely avoid cone biopsy.

Main Methods:

  • Retrospective review of 733 cone biopsies for CIN.
  • Analysis of cases with inadequate colposcopy, stratified by risk factors.
  • Comparison of cytologic, colposcopic biopsy, and cone biopsy findings.

Main Results:

  • Inadequate colposcopy cases with CIN 2 or less, negative ECC, and negative biopsy showed no invasive or microinvasive disease.
  • A significant proportion (16.7%) of patients with inadequate colposcopy could have potentially avoided cone biopsy based on specific criteria.
  • High-risk factors in inadequate colposcopy cases were associated with higher rates of CIN 3 and invasive/microinvasive carcinoma.

Conclusions:

  • Conservative management is a viable option for select patients with CIN and inadequate colposcopy.
  • Criteria including CIN 1-2 on biopsy and cytology, and a negative endocervical curettage (ECC), can guide conservative treatment decisions.
  • This approach can help avoid unnecessary cone biopsies, reducing patient morbidity.
