Abstract:
Many gynecological cancers, including epithelial and stromal ovarian cancers; endometrial carcinomas; and some gynecological sarcomas, in particular endometrial stromal sarcomas, express estrogen and/ or progesterone receptors. Hormonal therapy, typically progestogens or tamoxifen, is commonly prescribed to patients with potentially hormone-sensitive recurrent or metastatic gynecological cancers with very variable response rates and clinical benefit reported. Aromatase inhibitors are now widely used to treat postmenopausal women with hormone receptor-positive breast cancers as they have greater activity than tamoxifen and are generally better tolerated. The role of aromatase inhibitors in gynecological cancers is uncertain and has not been well studied, although they do appear to be active. The current evidence to support the use of hormonal therapies including aromatase inhibitors in gynecological cancers is reviewed, and the gaps in our knowledge highlighted.
Insights
Hormonal therapies, including aromatase inhibitors, show potential for gynecological cancers expressing estrogen or progesterone receptors. Further research is needed to clarify their efficacy and optimal use in treating these hormone-sensitive cancers.
Area of Science:
- Gynecologic Oncology
- Endocrinology
- Medical Oncology
Background:
- Many gynecological cancers (ovarian, endometrial, sarcomas) express estrogen/progesterone receptors.
- Hormonal therapies like progestogens and tamoxifen have variable efficacy in recurrent/metastatic disease.
- Aromatase inhibitors are effective and well-tolerated in hormone-receptor-positive breast cancer.
Purpose of the Study:
- To review current evidence on hormonal therapies, including aromatase inhibitors, for gynecological cancers.
- To highlight the uncertain role and limited study of aromatase inhibitors in this context.
- To identify gaps in knowledge regarding their use.
Main Methods:
- Literature review of studies on hormonal therapies in gynecological cancers.
- Analysis of evidence for aromatase inhibitor activity in hormone-sensitive gynecological malignancies.
- Identification of clinical trials and case reports.
Main Results:
- Estrogen and/or progesterone receptor expression is common in several gynecological cancers.
- Hormonal therapies demonstrate activity but with variable response rates.
- Aromatase inhibitors show potential but require further investigation.
Conclusions:
- Aromatase inhibitors may offer a therapeutic option for hormone-sensitive gynecological cancers.
- More research is essential to establish the role and optimize the use of aromatase inhibitors.
- Understanding receptor status is crucial for guiding hormonal therapy decisions.

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...
Cancer Vaccines
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
