Background: 4% of endometrial cancers are diagnosed in young women and 70% are nulliparous. Preserve fertility in these patients is of major interest. It is demonstrated that hysteroscopic resection of focal well-differentiated endometrioid adenocarcinoma, followed by progestins achieve a complete response rate of 95.3%. Recently, fertility-sparing treatment was proposed also in case of moderately differentiated endometrioid tumors, with a relatively high remission rate.
Objective: To show a new hysteroscopic approach, in case of fertility-sparing treatment of diffuse endometrial G2 endometrioid adenocarcinoma.
Materials and Methods: Stepwise demonstration of the technique with narrated video footage for the fertility-sparing management of diffuse endometrial G2 endometrioid adenocarcinoma, combining the use of a 15 Fr bipolar miniresectoscope and ‘three-steps’ resection technique (Karl Storz, Tuttlingen, Germany) with a Tissue Removal Device (TRD) (Truclear Elite Mini, Medtronic).
Main outcome measures: negative hysteroscopic assessment and endometrial biopsies at three and six months.
Results: Normal endometrial cavity and negative biopsies
Conclusion: Combined hysteroscopic technique, in case of diffuse endometrial G2 endometrioid adenocarcinoma, followed by double progestin therapy (Levonorgestrel releasing Intrauterine Device + Megestrole Acetate 160 mg/daily), may be associated with higher complete response rate; the use of TRD to complete the resection near tubal ostia may reduce risk of post-operative intrauterine adhesions and improve reproductive outcomes.
What is new? A novel, fertility-sparing surgical approach for diffuse endometrial G2 endometroid adenocarcinoma.
