Number of first cases of SRE.

SRECases (% of Total Cohort)

Radiation therapy609 (27.3)
Fracture266 (11.9)
Spinal cord compression37 (1.7)
Bone surgery22 (1.0)
Total (fracture, bone surgery, radiation therapy, or spinal cord compression)896 (40.1)

Notes. Cases identified using Medicare Provider Analysis and Review file, carrier claims (Physician/Supplier Part B), and outpatient claims. SREs on the date of the initial SRE during follow-up were identified. The sum of the cases of fracture, bone surgery, radiation, and spinal cord compression is greater than the total number of SRE cases, as patients may have had more than one type of SRE on the date of the first SRE.
SRE = skeletal-related event.
