ZOMETA in Advanced Cancers

Breast Cancer

Skeletal complications can shorten the survival of patients with advanced breast cancer1-3

Bone metastases strike the majority of patients with advanced breast cancer1

  • 65% to 75% of patients with advanced breast cancer develop bone metastases,* which may lead to bone complications or skeletal-related events (SREs)1†
  • A clinical trial demonstrated that without treatment with a bone-targeted agent2
    • 68% of patients with breast cancer and bone metastases experienced an SRE within 2 years
    • SRE frequency was approximately every 3 months

*Incidence at autopsy.
SREs are generally defined as pathological fractures, spinal cord compression, radiation or surgery to bone, or tumour-induced hypercalcaemia.4

With a median survival of more than 2 years in advanced breast cancer, the likelihood of an SRE is high2,5

Median time to first SRE vs survival chart

Median time to first SRE for patients treated with placebo in a clinical trial.
§Based on 381 consecutive patients diagnosed with stage IV breast cancer from 1994 to 2000 and treated at 3 French cancer centres.

Having an SRE may impact duration of survival3

  • In a 2007 retrospective analysis by Saad et al, pathological fracture significantly increased the hazard ratio for death by 52% in patients with advanced breast cancer and bone metastases3
