INCIDENCE

  • Most major solid tumors, as well as myeloma, have a propensity to involve bone
Tumor type Prevalence of bone metastases1
Prostate cancer 65% to 75%
Breast cancer 65% to 75%
Multiple myeloma 70% to 95%
Lung cancer 30% to 40%
Thyroid tumors 60%
Bladder cancer 40%
Renal cell carcinoma 20% to 25%

  • While some sites may be characterized by their radiological appearance as predominantly osteoblastic or predominantly osteolytic, it is now understood that most of these lesions have both a blastic and lytic component 3

THE MOST COMMON CAUSE OF PAIN IN ADVANCED CANCER

  • Even moderate pain may be difficult to control; incident pain, due to movement and commonly associated with bone metastases, can break through pain medications10

MANAGING BONE INVOLVEMENT

Opioid analgesics Bisphosphonates
  • Initial pain control
  • Significant side effects, particularly as dosage increases6
  • May reduce the frequency of skeletal-related events7
  • Targets lytic component8
External beam radiation
  • Relatively rapid & durable impact
  • Not for more than a few lesions
Radiopharmaceuticals Chemotherapy
  • Administered as a single injection
  • Lesion-seeking action9
  • Varying degrees of myelosuppression
  • Addresses underlying disease
  • Bone metastases may indicate that disease has progressed1

A long-term management challenge

  • Breast cancer patients whose disease has spread to the skeleton only have a median survival time of 2 to 4 years2
  • Prostate cancer patients with even advanced bone metastases—associated with severe bone pain and potentially debilitating complications—have a median survival of about 2 to 3 years4
