Bisphosphonates in the treatment of malignant bone disease

Abstract:
Tumor-induced osteolysis or lytic bone disease is mediated by osteoclast activation. Osteoclasts can be activated directly by products produced by tumors or indirectly through other nonmalignant cells. By reducing osteoclastic activity, bisphosphonates inhibit bone resorption. Since these agents were shown effective in treating other diseases associated with increased bone resorption, including cancer-related hypercalcemia and Paget's disease of bone, studies have been initiated to explore the use of bisphosphonates in patients with osteolytic bone metastases. Recent large randomized double-blind studies show the efficacy of these agents in reducing skeletal complications in patients with bone metastases from both breast cancer and multiple myeloma.

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...

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...

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...
