Abstract

OBJECTIVE:

To assess how the proportion of the cervical volume/length removed during treatment for cervical intraepithelial neoplasia (CIN) varies and whether this correlates to the pregnancy duration at delivery.

METHODS:

The present prospective observational study included 142 women undergoing CIN treatment at a university hospital during 2009-2013. The pretreatment and post-treatment cervical dimensions and cone size were measured with magnetic resonance imaging, three-dimensional transvaginal ultrasonography, or two-dimensional transvaginal ultrasonography, and the correlation between pregnancy outcomes and the relative proportion of the cervix excised was assessed.

RESULTS:

Pretreatment cervical volumes and cone volumes varied substantially (range 11-40 cm(3) and 0.6-8 cm(3), respectively). The proportion of the volume excised ranged from 2.2% to 39.4%. Sixteen (11%) women conceived following treatment; 12 had a live birth (seven at term, three preterm). The pregnancy duration at delivery was significantly correlated with the proportion of the cervical volume (r=-0.9; P<0.001) and length (r=-0.7; P=0.01) excised and the cone volume (r=-0.6; P=0.04).

CONCLUSION:

The pretreatment cervical dimensions and the proportions of the volume/length excised vary substantially, and the latter correlates with the pregnancy duration. Assessment of the proportion excised might help to stratify women at risk who need intensive surveillance when pregnant.
