Cervical dysplasia and pre-term birth in San Juan city hospital: a cohort retrospective study.

Unlabelled: Cervical dysplasia alters the release of cytokines and inflammatory mediators in pregnant woman with cervical dysplasia. This study evaluates a cohort of pregnant patients screened for cervical dysplasia to determine the relationship between cervical dysplasia and preterm labor (PTL).

Methods: Retrospective chart review of pregnant patients screened for cervical dysplasia at the San Juan City Hospital between October 2006 and December 2010. Patients with low or high-grade squamous intraepithelial lesions (LGSIL or HGSIL, respectively) were evaluated with colposcopy. Primary outcome was the event of PTL and the risk factor evaluated was presence of cervical dysplasia.

Results: A total of 2,059 patients were screened for cervical dysplasia and 59 were evaluated with colposcopy due to LGSIL or HGSIL. From those, 29% were negative for intraepithelial lesions and malignancy (NILM), 54% had cervical intraepithelial neoplasia (CIN)-1, 17% where diagnosed as CIN-2/3 where no invasive cervical cancer was identified. In the group of NILM, 24% had PTL compared to 18% in patients who screened negative on initial cytological evaluation. In cases where CIN-1 was confirmed by colposcopy 28% had PTL compared with 40% in patients with CIN-2/3. Other risk factors associated with PTL were not significantly different among the groups.

Conclusions: Cervical dysplasia in pregnancy may represent an increase risk for premature labor.
