Abstract:
Gynecological sarcomas are rare, constituting 3-5% of uterine malignancies. Endometrial stromal sarcomas and some uterine leiomyosarcomas are characterized by estrogen receptor (ER) and progesterone receptor (PgR) expression with variable impact on their clinical behavior and potential response to systemic therapies. A variety of hormonal treatments have been tested, since they act as targeted treatment against ER and PgR and have a tolerable side effect profile, which allows them to be administered for prolonged periods. Their role has been studied more extensively in endometrial stromal sarcomas, as the majority of cases are ER/PgR positive, while recently, an emerging role for hormonal manipulation has been described in ER/PgR-positive uterine leiomyosarcomas. Owing to the rarity and heterogeneous nature of uterine sarcomas, current treatment recommendations are based on small retrospective studies and case reports. This review comprises a critical appraisal of the existing data regarding hormonal manipulation in uterine sarcomas and attempts to make recommendations for endocrine treatments in specific settings, as well as suggest targets/medications for future research.
Insights
Hormonal therapies show promise for rare uterine sarcomas expressing estrogen and progesterone receptors. This review critically appraises current data and suggests future research directions for endocrine treatments.
Area of Science:
- Gynecologic Oncology
- Endocrinology
- Pathology
Background:
- Gynecological sarcomas are rare uterine malignancies (3-5% of cases).
- Endometrial stromal sarcomas and some uterine leiomyosarcomas express estrogen receptor (ER) and progesterone receptor (PgR).
- Hormonal treatments offer targeted therapy with a tolerable side effect profile for prolonged use.
Purpose of the Study:
- To critically review existing data on hormonal manipulation in uterine sarcomas.
- To provide recommendations for endocrine treatments in specific settings.
- To suggest future research targets and medications for ER/PgR-positive uterine sarcomas.
Main Methods:
- Comprehensive literature review of studies on hormonal manipulation in uterine sarcomas.
- Critical appraisal of retrospective studies and case reports.
- Analysis of data on ER/PgR expression and treatment response.
Main Results:
- Hormonal treatments have a well-studied role in endometrial stromal sarcomas due to frequent ER/PgR positivity.
- Emerging evidence supports hormonal manipulation in ER/PgR-positive uterine leiomyosarcomas.
- Treatment recommendations are often based on limited data owing to rarity and heterogeneity.
Conclusions:
- Hormonal manipulation is a viable therapeutic strategy for specific subtypes of uterine sarcomas.
- Further research is needed to establish optimal endocrine treatments and identify new therapeutic targets.
- Personalized endocrine therapy based on receptor status may improve outcomes for uterine sarcoma patients.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
