9.2 Plan Nutritional Strategies to Impact Hematological Wellness
4 min read•june 18, 2024
Hormonal therapy is a powerful weapon against hormone-dependent cancers. It works by blocking hormone production, interfering with receptor binding, or inducing receptor degradation. These treatments target breast, prostate, endometrial, and thyroid cancers.
Nurses play a crucial role in managing hormonal therapies. They educate patients on adherence, side effects, and lifestyle changes. Monitoring treatment response, administering medications, and collaborating with the healthcare team are key nursing responsibilities in hormonal cancer treatment.

- Hormonal therapy targets hormone-dependent cancers (hormone-sensitive cancers)
- Breast, prostate, endometrial, and thyroid cancers are commonly treated with hormonal therapy
- Mechanisms of action:
- Blocking hormone production
- Aromatase inhibitors (AIs) block estrogen synthesis by inhibiting the aromatase enzyme (anastrozole, letrozole)
- Gonadotropin-releasing hormone (GnRH) agonists/antagonists suppress testosterone production by inhibiting the hypothalamic-pituitary-gonadal axis (leuprolide, goserelin)
- Interfering with hormone receptor binding
- Selective estrogen receptor modulators (SERMs) like tamoxifen bind to estrogen receptors and block estrogen signaling in breast tissue
- Antiandrogens like flutamide and bicalutamide compete with androgens for binding to androgen receptors in prostate cancer cells
- Inducing hormone receptor degradation
- Selective estrogen receptor degraders (SERDs) like fulvestrant bind to estrogen receptors and promote their degradation, reducing estrogen signaling
- Blocking hormone production
Clinical applications of hormonal therapies
- Breast cancer
- Adjuvant therapy for hormone receptor-positive (HR+) early-stage breast cancer to reduce recurrence risk
- Treatment for metastatic HR+ breast cancer to slow disease progression and improve survival
- Potential risks: hot flashes, joint pain, osteoporosis, increased risk of endometrial cancer with tamoxifen use
- Prostate cancer
- Treatment for advanced or metastatic prostate cancer to slow disease progression and alleviate symptoms
- Potential risks: hot flashes, sexual dysfunction, osteoporosis, cardiovascular events
- Endometrial cancer
- Treatment for advanced or recurrent endometrial cancer to control tumor growth and manage symptoms
- Potential risks: venous thromboembolism, endometrial hyperplasia, uterine cancer with tamoxifen use
- Thyroid cancer
- Suppression of thyroid-stimulating hormone (TSH) in differentiated thyroid cancer to reduce the risk of recurrence
- Potential risks: hyperthyroidism, osteoporosis, atrial fibrillation
Endocrine System and Hormonal Therapy
- The endocrine system plays a crucial role in hormone production and regulation
- Steroid hormones, such as estrogen and testosterone, are primary targets for hormonal therapy
- Receptor binding is a key mechanism in hormone action and is often targeted by hormonal therapies
- Endocrine resistance can develop over time, reducing the effectiveness of hormonal treatments
- Menopausal symptoms may be exacerbated or induced by certain hormonal therapies
Nursing considerations for hormonal therapy
- Patient education

- Administer injectable medications (e.g., GnRH agonists) as prescribed, providing patient education on self-injection techniques when appropriate
- Collaboration with the healthcare team
- Communicate patient concerns and treatment-related issues to the oncologist to ensure timely management and adjustments to the treatment plan
- Coordinate care with other specialists (e.g., endocrinologists, gynecologists) as needed to address specific hormone-related concerns or complications
Patient education for hormonal treatment
- Pre-treatment education
- Explain the purpose and expected outcomes of hormonal therapy, emphasizing its role in controlling cancer growth and improving prognosis
