Low-Grade Endometrial Stromal Sarcoma - a Review

Area of Science:

• Gynecologic Oncology
• Pathology
• Endocrinology

Background:

• Low-grade endometrial stromal sarcoma (LG-ESS) is a rare uterine malignancy.
• Historical research often combined LG-ESS with other uterine sarcomas due to classification challenges.
• Distinguishing LG-ESS from high-grade endometrial stromal sarcoma and undifferentiated uterine sarcoma has been difficult.

Purpose of the Study:

• To review current understanding and treatment of LG-ESS.
• To highlight the need for LG-ESS to be studied as a distinct entity.
• To identify areas for improved therapeutic strategies.

Main Methods:

• Literature review of existing studies on LG-ESS.
• Analysis of treatment modalities including surgery, endocrine therapy, and radiotherapy.
• Discussion of diagnostic challenges and prognostic factors.

Main Results:

• Hysterectomy and adnexectomy are the primary surgical treatments for LG-ESS.
• The efficacy of lymphadenectomy and tumor debulking remains uncertain.
• Endocrine therapies (gestagens, aromatase inhibitors) are considered for advanced stages; radiotherapy offers locoregional control but requires careful risk-benefit assessment.

Conclusions:

• LG-ESS requires further dedicated research to optimize patient treatment.
• Repeat surgery is the preferred approach for recurrent disease.
• A clearer understanding of LG-ESS as a unique entity is crucial for advancing therapeutic options.
