The results of different fertility-sparing treatment modalities and obstetric outcomes in patients with early endometrial cancer and atypical endometrial hyperplasia: Case series of 30 patients and systematic review
Objective Increasing incidence of endometrial cancer and late motherhood enhance conservative management in clinical practice. Although different approaches to fertility-sparing treatment are possible, it is still unknown which patients will benefit more from systemic or local treatment. Aim of this paper is to analyze the effectiveness of different methods of conservative management and obstetric outcomes in patients with early endometrial cancer and atypical endometrial hyperplasia. Study design 30 patients (10 with atypical endometrial hyperplasia, 20 with endometrial cancer) treated conservatively were included to retrospective analysis. 24 patients receiving progestins were divided into 2 groups according to the dose (low and high dose); 6 patients were treated with levonorgestrel releasing intrauterine device. Effectiveness of therapy (complete, partial or absent) and obstetric outcomes (number of pregnancies and live births) were assessed. Electronic databases (MEDLINE, Web of Science, Embase) were searched for articles according to criteria: 1) fertility-sparing treatment of endometrial cancer/atypical endometrial hyperplasia in patients of reproductive age, 2) assessment of pregnancy/obstetric results. The risk of bias was assessed with the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Case Series. Results Complete and partial remission were achieved in 21 and 3 patients, respectively. 6 patients did not respond to treatment. Relapse was diagnosed in 6 patients. Probability of complete remission according to low-, high-dose regimen and levonorgestrel-releasing intrauterine device were 55.6% (46.5%–64.7%), 73.3% (65.2%–81.4%) and 83.3% (76.5%–90.1%) respectively. 4 patients get pregnant and 3 of them born children. 25 studies (21 retrospective, 4 prospective) with 812 participants were included in the systematic review. The most studied was progestin based treatment. Complete and partial response to fertility-sparing management was diagnosed in 634 and 38 patients, respectively. Relapse was diagnosed in 170 patients. Median times of follow-up range from 17 (1–45) to 98 (35–176) months. The total number of pregnancies and live births were 352 and 246, respectively. Conclusions Fertility-sparing treatment is a safe method of management in young women with endometrial cancer/atypical endometrial hyperplasia. While the main goal of conservative management is preserving the possibility of having children, only a small number of women will become pregnant and give birth.
