Abstract

Insights

Bone-modifying therapies like denosumab and bisphosphonates are crucial for breast cancer patients. Denosumab shows promise in preventing bone loss and skeletal events, potentially improving outcomes.

Area of Science:

  • Oncology
  • Bone Biology
  • Pharmacology

Background:

  • Bone metastases are common in breast cancer.
  • Cancer treatment-induced bone loss (CTIBL) is a growing concern.
  • Altering the bone microenvironment may impact tumor growth.

Purpose of the Study:

  • To review the role of denosumab and bisphosphonates in breast cancer bone complications.
  • To evaluate denosumab's potential as adjuvant therapy.

Main Methods:

  • Literature search of medical databases and conference proceedings.
  • Focus on denosumab and bisphosphonates in early and advanced breast cancer.
  • Inclusion of clinical trials investigating these agents.

Main Results:

  • Bisphosphonates (BPs) are established for CTIBL prevention/treatment and adjuvant therapy in early breast cancer (EBC).
  • Denosumab, a RANK ligand inhibitor, is approved for osteoporosis and preventing skeletal-related events (SREs).
  • Denosumab has a favorable toxicity profile compared to BPs and may improve cancer outcomes.

Conclusions:

  • Denosumab is effective in treating bone complications of breast cancer.
  • Denosumab shows potential as an adjuvant therapy for breast cancer.

Bone Remodeling01:40

Bone Remodeling

Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
Bone Disorders01:29

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
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 Tissue01:17

Hormones and Bone Tissue

The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
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...
