Fertility-Sparing Treatment in Young Women Diagnosed with Endometrial Cancer: Review of Safety, Pregnancy Outcomes, and Current Recommendations.

With the rising incidence of endometrial cancer, including among young women, and the trend of increasing age among first-time mothers, the need for safe and effective fertility-sparing treatments for endometrial cancer and atypical endometrial hyperplasia has become crucial. Focusing on studies from the past decade, this review synthesizes findings on the safety and outcomes of fertility-sparing treatments for endometrial cancer and atypical endometrial hyperplasia and provides an overview of current treatment recommendations. Fertility-sparing treatment, including hysteroscopic tumor resection followed by hormonal therapy with oral progestins and/or the insertion of a levonorgestrel-releasing intrauterine device, can be offered to a selected group of women of reproductive age who wish to preserve their ability to become pregnant in the future. The safety of conservative treatment for women diagnosed with Stage 1A, Grade 1 endometrial cancer without myometrial invasion is high; however, current evidence on the safety of this treatment for women with Grade 1, Stage 2 endometrial cancer is limited. Even though the success rate in terms of pregnancies and deliveries is high, it is not as high as in the general population, and women should be informed of the potential need for assisted reproductive technology.
