A Key Player in Targeting Hormone-Responsive Tumors
Hormonal therapy, also called endocrine therapy, is an important cancer treatment approach for selected hormone-responsive cancers. It works by blocking hormone effects or reducing hormone production that can help certain cancer cells grow.
What Is Hormonal Therapy?
Hormonal therapy, also known as endocrine therapy, is a cancer treatment used when cancer growth is influenced by hormones. It is particularly important in certain breast and prostate cancers.
Depending on the cancer, hormonal therapy may work by blocking hormones from attaching to cancer cells or by reducing the amount of a particular hormone available to the body.
The purpose is to reduce or stop hormone-related signals that can support the growth of hormone-responsive cancer cells.
Hormone-Responsive Cancers
Hormonal therapy is primarily used in cancers whose growth is influenced by hormones. Its role depends on the cancer's biological characteristics and the individual treatment plan.
Breast Cancer
Hormonal therapy is commonly used for hormone receptor-positive breast cancer. It may be used before or after other treatments depending on the individual situation.
Prostate Cancer
Many prostate cancers depend on androgen hormones such as testosterone. Hormonal treatment can reduce androgen activity and slow cancer growth in appropriate situations.
Selected Other Cancers
Hormonal therapy may also have a role in selected uterine or endometrial cancers and some other hormone-responsive cancers depending on their biological characteristics.
How Hormonal Therapy Acts on Cancer
Different hormonal treatments act in different ways. Some block hormone receptors, while others reduce hormone production or interfere with hormone signaling.
Estrogen Signaling
Some breast cancers use estrogen signals to support their growth. Certain endocrine treatments interfere with estrogen signaling or reduce estrogen availability.
Progesterone Signaling
Progesterone receptor status can be part of the biological assessment of some breast cancers and may influence treatment planning.
Androgen Activity
Prostate cancer can be influenced by androgens such as testosterone. Treatments may reduce androgen production or block its effects.
Hormone Receptors
Testing for hormone receptors can help doctors determine whether endocrine therapy may be useful in selected cancers.
Types of Hormonal Therapy
Several categories of endocrine treatments are available. The choice depends on the cancer type, receptor status, treatment setting, previous therapy, and individual patient factors.
Selective Estrogen Receptor Modulators
SERMs interact with estrogen receptors and can block or modify estrogen signaling in specific tissues. They are used in selected hormone receptor-positive breast cancer settings.
Aromatase Inhibitors
Aromatase inhibitors reduce the body's production of estrogen and are commonly used in appropriate hormone receptor-positive breast cancer treatment settings.
Hormone-Suppressing Therapies
Medicines that affect the hypothalamic-pituitary-gonadal hormone pathway can reduce production of sex hormones and are used in selected breast or prostate cancer situations.
Androgen Receptor Blockers
Anti-androgen medicines block the effects of male hormones on prostate cancer cells and can form part of hormone-based prostate cancer treatment.
The Role and Potential Benefits of Hormonal Therapy
When a cancer is hormone-responsive, endocrine therapy can become an important part of long-term cancer management.
Effective Hormone Control
Hormonal therapy can help slow or control hormone-responsive cancers by interfering with signals that support cancer growth.
Long-Term Management
In selected cancers, endocrine therapy may be given over an extended period as part of a long-term treatment or recurrence-risk reduction strategy.
Combination Treatment
Hormonal therapy can sometimes be combined with surgery, radiation, chemotherapy, targeted therapy, or other treatments depending on the cancer.
Oral or Injectable Options
Depending on the medicine, hormonal therapy may be administered as a tablet, injection, or another form of treatment.
A Hormonal Treatment Plan Made for Your Cancer
Hormonal therapy is not appropriate for every cancer. Medical oncologists consider the biological characteristics of the cancer and the patient's overall situation before recommending treatment.
For breast cancer, hormone receptor testing can help determine whether endocrine therapy may be beneficial.
The type, stage, and extent of cancer influence the role of hormonal therapy within the overall treatment plan.
Surgery, chemotherapy, radiation, or previous hormonal treatments may affect future treatment decisions.
Age, other health conditions, medications, possible side effects, and individual treatment goals are considered.
