The impact on obstetric outcomes following complete amputation of the cervix uteri in fertility preservation surgery for cervical neoplasm.

Objectives: Radical trachelectomy is offered to women with early-stage cervical neoplasia who desire fertility. The presence of isthmic glands within histological specimens suggests complete cervical amputation and as such, we examined if the presence of these glands in surgical specimens adversely affects obstetric outcomes.
Study Design: The study cohort comprises 43 consecutive cases of early-stage cervical neoplasia. The presence of isthmic glands in pathological specimens was correlated with obstetric outcomes. Univariate and multivariate analyses were constructed to identify clinicopathological factors associated with adverse obstetric outcomes.
Results: 43 patients underwent fertility sparing surgery; radical (30; 69.8 %) or simple trachelectomy (13; 30.2 %). Of these, 26 (60.5 %) had isthmic glands within the surgical specimen. Isthmic gland presence was not influenced by surgery radicality, disease stage, histological diagnosis, or surgical approach. Obstetric outcomes were available for 36 patients, with 27 attempting conception post-trachelectomy and 15 (55.6 %) achieving at least one pregnancy. Of 21 total pregnancies, the miscarriage and live birth rates were 7.4 % and 85.0 %, respectively. The presence of isthmic glands did not influence the overall conception rate, with 53.8 % of women with complete cervical amputation conceiving compared to 57.1 % of those without (p = 0.8632). Complete removal of the cervix did not increase premature deliveries <37 weeks gestation (p = 0.2521).
Conclusions: The presence of isthmic glands in trachelectomy specimens provides a reliable surrogate marker for complete cervical amputation. In cases where complete cervical amputation is required to achieve maximum oncological outcomes, patients may be assured that there is little evident impact on fertility and obstetric outcomes.
