Practice Essentials. Metastatic bone disease occurs when cancer spreads from a primary organ site to bone. The spine is the most common location of metastatic disease. See the image below. Lateral radiograph shows sclerotic metastasis of the L2 vertebra in a year-old man with prostatic carcinoma. Cancer that begins in an organ, such as the lungs, breast, or prostate, and then spreads to bone is called metastatic bone disease (MBD). More than million new cancer cases are diagnosed each year. Approximately 50% of these tumors can spread (metastasize) to the skeleton. Abstract. Background: Bone is a frequent site of metastases in advanced cancer and is associated with significant skeletal morbidity. Current treatment options.

Bowel incontinence Weakness in the legs or arms High levels of calcium in the blood hypercalcemiawhich can cause nausea, vomiting, constipation and confusion When to see a doctor If you experience persistent signs and symptoms that worry you, make an appointment metastatic bone disease your doctor.

This increase in fracture rate and its consequences associated with use of an AI or ADT has not been metastatic bone disease addressed in the oncology setting in the past.

Metastatic bone disease: clinical features, pathophysiology and treatment strategies.

Increased awareness and approval of the osteoprotective agent denosumab, in this non-metastatic setting, has led to a significant reduction in bone fractures in postmenopausal breast cancer patients treated in the adjuvant setting with an AI and non-metastatic prostate cancer patients treated with ADT 89.

In addition to anti-hormonal treatment, prolonged chemotherapy can also affect the endocrine output of reproductive hormones critically necessary for metastatic bone disease healthy bone metabolism 10 Metastasis to the bone can present itself as either lytic, blastic or as mixed lesions In osteolytic bone lesions, bone resorption exceeds the rate of bone formation, whereas in osteoblastic lesions the opposite is true.

In both cases, a fragile bone structure is produced. Bone metastases form breast cancer have been described as prototypic osteolytic lesions, whereas bone metastases from prostate cancer as osteoblastic metastases. Histologically, however, accelerated osteolytic and osteoblastic pathological processes can coexist in the same lesion, irrespective of the radiological appearance Various biological factors endorse the bone as a common site of cancer metastasis.

Besides a favorable high blood flow to the red bone marrow, adhesive factors in the bone marrow stroma and the special environment within the hematopoetic stem cell niche allow tumor cells to take up residency and dormancy, thereby evading possible effects of systemic therapy About half the metastatic bone disease with these lesions suffer skeletal complications like pathological fractions, spinal cord compression and eminent pain requiring radiation therapy or surgery.

These four complications are referred to as skeletal-related events SRE and confer morbidity and major loss of quality of life upon patients with metastatic bone disease of the bone. Several studies have even shown a reduction in overall survival 15 - Pathological fractures and the necessity of radiation therapy are the most common SREs, emphasizing the extent of bone damage and pain associated with metastasis to the bone.

Such pain-inducing complications further lead metastatic bone disease immobility and loss of functional independence Current management of bone metastases entails a multidisciplinary approach since cancer is an expression of a systemic disease.


Therefore, metastatic bone disease various disciplines like orthopedic surgery, radiation oncology and medical oncology into the big picture of an individual case can cause some friction. The best course of action is not always straight forward since each specialty might look at the problem at hand from a different angle.

Bone metastasis

The best way to unite these different angles and views is often through guidelines and algorithms, which can yield a foundation for metastatic bone disease making but can metastatic bone disease be tailored to individual needs, often the case in advanced cancer.

Thermal ablation techniques are increasingly being used in the palliative treatment of painful metastatic bone disease. Although the majority of patients experience complete or partial relief of pain following external radiation therapy, the effect is not immediate and has been shown in some studies to be transient in more than half of patients.

Bisphosphonates are a man-made version of a naturally occurring compound called pyrophosphate that prevents bone breakdown.

Metastatic bone disease: clinical features, pathophysiology and treatment strategies.

They are a class of medications widely used to treat or prevent osteoporosis and to treat other bone diseases such as Paget's Diseaseas well as in the treatment of elevated blood calcium. These medications suppress bone breakdown caused by cells called osteoclasts, and, can indirectly metastatic bone disease the bone forming cells called osteoblasts to make new bone.

Strengthening bone and relieving bone metastatic bone disease has made bisphosphonates a good treatment for cancer that has spread to the bone.

However, treatment of bone metastases is not curative. There is increasing evidence that bisphosphonates can prevent bone complications in some metastatic bone disease cancers and may even improve survival in some cancers.

Most researchers agree that these medications are more helpful in osteolytic lesions and less so in osteoblastic metastasis in terms of bone restoration and health, but the bisphosphonates are able to metastatic bone disease pain associated with both types of lesions.

Bisphosphonates can be given either orally by mouth or intravenously IVhowever in oncology care it is generally given by IV.
