Abstract:
A few breakthroughs have been accomplished for the treatment of ovarian cancer, the most deadly gynecologic carcinoma, in the current era of targeted oncologic treatment. The estrogen receptor was the first target of such treatments with the introduction of tamoxifen four decades ago in breast cancer therapeutics. Attempts to duplicate the success of hormonal therapies in ovarian cancer met with mixed results, which may be due to an inferior degree of hormone dependency in this cancer. Alternatively, this may be due to the failure to clearly identify the subsets of ovarian cancer with hormone sensitivity. This article reviews the expression of hormone receptors by ovarian cancer cells, the prognostic value of these expressions, and their predictive capacity for response to hormonal agents. The possible ways ahead are briefly discussed.
Insights
Hormone receptor expression in ovarian cancer offers potential for targeted therapies. Identifying hormone-sensitive subsets is crucial for improving treatment outcomes in this deadly gynecologic cancer.
Area of Science:
- Gynecologic Oncology
- Endocrinology
- Cancer Therapeutics
Background:
- Ovarian cancer treatment has seen limited success with targeted therapies compared to breast cancer.
- Hormonal therapies, like tamoxifen, were successful in breast cancer but yielded mixed results in ovarian cancer.
- This discrepancy may stem from lower hormone dependency or failure to identify sensitive patient subsets in ovarian cancer.
Purpose of the Study:
- To review hormone receptor expression in ovarian cancer.
- To evaluate the prognostic value of these expressions.
- To assess the predictive capacity of hormone receptors for hormonal agent response.
Main Methods:
- Review of existing literature on hormone receptor expression in ovarian cancer.
- Analysis of studies correlating receptor expression with patient prognosis.
- Examination of data on hormonal therapy response based on receptor status.
Main Results:
- Ovarian cancer cells express hormone receptors, but their role is less defined than in breast cancer.
- Expression levels may have prognostic implications, though not consistently established.
- Predictive value for hormonal agents is variable and requires further investigation.
Conclusions:
- Hormone receptor status in ovarian cancer warrants further research for targeted treatment strategies.
- Identifying specific patient populations sensitive to hormonal therapy is key.
- Future research should focus on refining diagnostic and therapeutic approaches based on hormone receptor expression.

Target Cell Response to Hormones
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

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...
