Hormone replacement therapy (HRT) is generally safe after gynecological cancers, except for breast and endometrial cancers. Non-hormonal options are available for breast cancer patients, while HRT use in endometrial cancer requires careful risk-benefit discussion.
Area of Science:
- Gynecological Oncology
- Reproductive Endocrinology
- Oncology
Background:
- Menopause is common in women undergoing gynecological cancer treatment.
- Early menopause can result from surgery, chemotherapy, or radiotherapy.
Purpose of the Study:
- To review evidence for and against hormone replacement therapy (HRT) post-gynecological cancer.
- To assess HRT risks and benefits in various gynecological cancer survivors.
Main Methods:
- Literature review of biological and clinical evidence.
- Analysis of studies on HRT use in breast, endometrial, and other gynecological cancers.
Main Results:
- No biological evidence suggests HRT increases recurrence risk for most gynecological cancers (excluding breast/endometrial).
- HRT use in endometrial cancer lacks conclusive data; estrogen may be considered with informed consent.
- HRT is contraindicated in breast cancer patients, despite conflicting trial results.
Conclusions:
- HRT safety varies significantly depending on the type of gynecological cancer.
- Careful patient counseling regarding risks and benefits is crucial for HRT decisions.
- Non-hormonal therapies are recommended for breast cancer patients experiencing menopausal symptoms.

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...
Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.

Gonadal and Placental Hormones
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...
