Oncologic and obstetric outcomes and complications during pregnancy after fertility-sparing abdominal trachelectomy for cervical cancer: a retrospective review

Background: Trachelectomy was developed as a fertility-sparing surgery for early-stage cervical cancer in patients of childbearing age. The purpose of this study is to evaluate oncologic and obstetric outcomes and complications after abdominal trachelectomy. Methods: We began to perform abdominal trachelectomy in 2005. Our institutional review board approved this clinical study, and fully informed consent was obtained from each patient. The medical records of patients who underwent trachelectomy were retrospectively reviewed. Results: We performed 151 abdominal trachelectomies (89 radical trachelectomies, 48 modified radical trachelectomies, and 14 simple trachelectomies). The median age of the patients was 33 years, and the median postoperative follow-up period was 61 months. Although one patient experienced recurrence at the preserved cervix, none died after treatment. A total of 61 patients attempted to conceive after trachelectomy, and 21 pregnancies were achieved in 15 women. Hence, the pregnancy rate among patients who attempted to conceive was 25%. Fifteen babies were delivered by cesarean section between gestational weeks 23 and 37. Six babies were delivered at term. Six cases of preterm premature rupture of the membranes occurred. Varices appeared around the uterovaginal anastomotic site in five patients. Conclusions: Our data indicate that the oncologic outcome was excellent but infertility treatment was necessary to achieve the majority of conceptions. Additionally, preterm premature rupture of the membranes and premature delivery were frequently observed. An improved pregnancy rate and prevention of complications during pregnancy are issues that should be addressed in future studies.
