Osteoclast-targeted therapies like zoledronic acid and denosumab help manage bone metastases in advanced prostate cancer. Androgen-deprivation therapy (ADT) increases fracture risk, but bisphosphonates and denosumab show promise in preventing fractures.
Area of Science:
- Oncology
- Bone Metastasis Research
- Pharmacotherapy
Background:
- Bone metastases significantly impact men with advanced prostate cancer, causing pain, fractures, and spinal cord compression.
- Osteoclast activation is linked to disease progression, skeletal complications, and mortality in prostate cancer.
- Androgen-deprivation therapy (ADT) for prostate cancer is associated with increased risk of osteoporosis and fragility fractures.
Purpose of the Study:
- To review current osteoclast-targeted therapies for managing bone metastases in prostate cancer.
- To evaluate the role of bisphosphonates and denosumab in preventing skeletal-related events and fractures.
- To discuss the application of fracture risk assessment models for men receiving ADT.
Main Methods:
- Review of existing literature on zoledronic acid, denosumab, and other bisphosphonates in prostate cancer bone metastases.
- Analysis of data from phase III clinical trials investigating these therapies.
- Discussion of the World Health Organization's fracture risk assessment tool (FRAX) in the context of ADT.
Main Results:
- Zoledronic acid is a standard treatment for castration-resistant prostate cancer with bone metastases, reducing skeletal-related events.
- Denosumab is an experimental therapy targeting receptor activator of nuclear factor-kappaB ligand, with ongoing trials for efficacy in bone metastases prevention.
- Bisphosphonates and denosumab have demonstrated benefits in improving bone mineral density and reducing fragility fractures in men receiving ADT.
Conclusions:
- Osteoclast-targeted therapies are crucial for managing bone metastases and associated complications in prostate cancer.
- Further research is needed to optimize zoledronic acid dosing, frequency, and duration.
- The FRAX tool is recommended for assessing fracture risk in men undergoing ADT due to the lack of a prostate cancer-specific algorithm.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Hormones and Bone Tissue
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
Essential Minerals for Bone Health
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
