Fracture in Invasive Breast Cancer
Assessing fracture incidence after BC diagnosis
Occurrence of fractures in invasive breast cancer raises the possibility of cancer-induced impairment in bone quality, according to a study of 422 women with invasive breast cancer. Researchers found:
• 79 women sustained fractures during the observation period.
• 27 women sustained fractures at multiple skeletal sites, with a total of 116 fractures.
• Incidence of fractures was 40 per 1000 person–years.
• Women who sustained fractures were mostly white and had family history of osteoporosis or history of prior fracture.
• Fractures occurred a median 4.0 years after cancer diagnosis.
• Fracture cases fell within the low bone mass range.
• Fractures usually occurred in lower extremities, vertebral, and wrist sites.
• Hip fractures accounted for 11% of fractures, occurring at a median age of 61 years.
