How Cancer Affects the Bones

By knowing more about bone complications from cancer and the impact it may have on the bones, you can help your patients better understand their disease. You'll also be better equipped to answer any questions they may have.

Understanding Bone Growth and Renewal

Bone is a living tissue in a constant state of growth. Made predominantly of the protein collagen (which provides a soft, malleable framework) and calcium phosphate (a mineral that ensures strength and solidity), the bone's continuous process of renewal is known as remodeling.¹

Bone remodeling takes place through the following cycle:²

Resorption—Osteoclasts remove fatigued or damaged bone cells, creating a cavity
Reversal—Mononuclear cells prepare surface for new osteoblasts to begin building bone
Formation—Osteoblasts synthesize a matrix and lay down new bone, replacing resorbed bone
Resting—A period of little cellular activity follows the formation stage

In patients with bone metastases, metastatic tumor cells create a vicious cycle of osteolytic and osteoblastic bone destruction.³

This process of bone destruction puts your patients at risk for skeletal related events (SREs) and other severe complications, including:⁴

Bone pain
Impaired mobility
Hypercalcemia
Pathological fracture
Spinal cord or nerve root compression
Bone marrow infiltration

Bone Metastases from Solid Tumors

The skeleton is one of the most common sites for metastases in solid tumors such as breast cancer, lung cancer, kidney cancer, and prostate cancer.⁵ Bone metastases can make bones fragile and cause SREs such as fractures, spinal compression, and hypercalcemia.⁵

The prevalence of bone metastases from all tumor types is approximately 500,000 patients per year in the U.S.⁵ Among solid tumor types, bone metastases occur in 65%-75% of patients with breast and prostate cancer, in 30%-40% of those with lung cancer, and in 20%-25% of patients with renal cancer.⁵

Bone Complications from Multiple Myeloma

In multiple myeloma, cancerous plasma cells form tumors, usually in the bone marrow. This type of tumor is called a myeloma. Myeloma cells can cause parts of the bone to dissolve, making them susceptible to fractures and other SREs.⁶

Patients with multiple myeloma are at high risk of SREs. In fact, 70-95% of patients with multiple myeloma have osteolytic involvement at the time of diagnosis.⁵

With the introduction of high dose therapy followed by stem cell transplant and incorporation of novel agents, the median survival in patients with multiple myeloma has increased from 3 to 6 years from diagnosis. But SREs can be disabling for these patients, and reducing the risk for and frequency of SREs may help maintain their skeletal health.⁷

ZOMETA is contraindicated in patients with hypersensitivity to zoledronic acid or any components of ZOMETA. Hypersensitivity reactions, including rare cases of urticaria and angioedema, and very rare cases of anaphylactic reaction/shock, have been reported. Patients being treated with ZOMETA should not be treated with Reclast^® (zoledronic acid) as they contain the same active ingredient.

Patients with HCM must be adequately rehydrated prior to use of ZOMETA and loop diuretics (if applicable). Loop diuretics should be used with caution in combination with ZOMETA to avoid hypocalcemia. ZOMETA should be used with caution with other nephrotoxic drugs. Carefully monitor serum calcium, phosphate, magnesium, and serum creatinine following initiation of ZOMETA. Short-term supplemental therapy may be necessary.

In patients with impaired renal function, the risk of adverse reactions (especially renal adverse reactions) may be greater. Consider individual patient risk/benefit profile before starting ZOMETA therapy in HCM patients with severe renal impairment. ZOMETA treatment is not recommended in patients with bone metastases with severe renal impairment. Preexisting renal insufficiency and multiple cycles of ZOMETA and other bisphosphonates are risk factors for subsequent renal deterioration with ZOMETA. Do not use doses greater than 4 mg. ZOMETA should be administered by IV infusion over no less than 15 minutes. Monitor serum creatinine before each dose.

Osteonecrosis of the jaw (ONJ) has been reported predominantly in cancer patients treated with intravenous bisphosphonates, including ZOMETA. Many of these patients were also receiving chemotherapy and corticosteroids, which may be risk factors for ONJ. Postmarketing experience and the literature suggest a greater frequency of reports of ONJ based on tumor type (advanced breast cancer, multiple myeloma) and dental status (dental extraction, periodontal disease, local trauma, including poorly fitting dentures). Many reports of ONJ involved patients with signs of local infection, including osteomyelitis. Cancer patients should maintain good oral hygiene and should have a dental examination with preventive dentistry prior to treatment with bisphosphonates. While on treatment, these patients should avoid invasive dental procedures, if possible, as recovery may be prolonged. For patients who develop ONJ while on bisphosphonate therapy, dental surgery may exacerbate the condition. For patients requiring dental procedures, there are no data available to suggest whether discontinuation of bisphosphonate treatment reduces the risk of ONJ. A causal relationship between bisphosphonate use and ONJ has not been established. Clinical judgment of the treating physician should guide the management plan of each patient based on individual benefit/risk assessment.

ZOMETA should not be used during pregnancy. Women of childbearing potential should be advised to avoid becoming pregnant. If the patient becomes pregnant or plans to breast-feed while taking this drug, the patient should be apprised of the potential harm to the fetus or baby.

In postmarketing experience, severe and occasionally incapacitating bone, joint, and/or muscle pain has been reported in patients taking bisphosphonates including ZOMETA. Discontinue use if severe symptoms develop, and a subset of patients had recurrence of symptoms when rechallenged with the same drug or another bisphosphonate. There have been reports of bronchoconstriction in aspirin sensitive patients receiving bisphosphonates.

Insufficient data exist on how to safely use ZOMETA in HCM patients with hepatic impairment.

Acute-phase reaction symptoms can occur in HCM patients, with fever most commonly reported (44% with ZOMETA vs. 33% with pamidronate). Patients may occasionally experience flu-like syndrome (fever, chills, flushing, bone pain and/or arthralgias and myalgias). The most common adverse events (≥10%) in HCM clinical trials, regardless of causality, with ZOMETA 4 mg (n=86) were as follows: fever (44%), nausea (29%), constipation (27%), anemia (22%), dyspnea (22%), diarrhea (17%), abdominal pain (16%), progression of cancer (16%), insomnia (15%), vomiting (14%), anxiety (14%), urinary tract infection (14%), hypophosphatemia (13%), confusion (13%), agitation (13%), moniliasis (12%), hypokalemia (12%), coughing (12%), skeletal pain (12%), hypotension (11%), and hypomagnesemia (11%). In controlled HCM clinical trials, adverse events (5-10% frequency) occurring in greater incidence with ZOMETA than pamidronate include: asthenia, chest pain, leg edema, mucositis, dysphagia, granulocytopenia, thrombocytopenia, pancytopenia, non-specific infection, hypocalcemia, dehydration, arthralgias, headache and somnolence. Injection site reactions (redness, swelling) have been infrequently reported.

The most common adverse events (≥15%) in bone metastases clinical trials, regardless of causality, with ZOMETA 4 mg (n=1031) were as follows: bone pain (55%), nausea (46%), fatigue (39%), anemia (33%), pyrexia (32%), vomiting (32%), constipation (31%), dyspnea (27%), diarrhea (24%), weakness (24%), myalgia (23%), anorexia (22%), cough (22%), arthralgia (21%), lower-limb edema (21%), malignant neoplasm aggravated (20%), headache (19%), dizziness (excluding vertigo) (18%), insomnia (16%), decreased weight (16%), back pain (15%), and paresthesia (15%). Patients should also be made aware of the potential for abdominal pain.

Ocular adverse events may occur with bisphosphonates, including ZOMETA. Cases of uveitis, scleritis, episcleritis, conjunctivitis, iritis, and orbital inflammation including orbital edema have been reported during postmarketing use. In some cases, symptoms resolved with topical steroids.

Caution is advised when bisphosphonates, including ZOMETA, are administered with aminoglycosides, loop diuretics, and potentially nephrotoxic drugs.

Patients with multiple myeloma and bone metastases due to solid tumors should be administered an oral calcium supplement of 500 mg and a multiple vitamin containing 400 IU of vitamin D daily.
