• To quantify the impact of androgen deprivation therapy (ADT) in men with a high baseline risk of skeletal complications and evaluate the risk of mortality after a fracture.


• We studied 75 994 men, aged 66 years, with localized prostate cancer from the Surveillance, Epidemiology and End Results–Medicare linked data.

• Cox proportional hazard models were employed to evaluate the risk.


• Men with a high baseline risk of skeletal complications have a higher probability of receiving ADT than those with a low risk (52.1% vs 38.2%, P < 0.001).

• During the 12-year follow-up, more than 58% of men with a high risk and 38% of men with a low risk developed at least one fracture after ADT.

• The dose effect of ADT is stronger among men who received ADT only compared to those who received ADT with other treatments.

• In the high-risk group, the fracture rate increased by 19.9 per 1000 person-years (from 52.9 to 73.0 person-years) for men who did not receive ADT compared to those who received 18 or more doses of gonadotropin-releasing hormone agonist among men who received ADT only, and by 14.2 per 1000 person-years (from 45.2 to 59.4 person-years) among men who received ADT and other treatments.

•Men experiencing a fracture had a 1.38-fold higher overall mortality risk than those who did not (95% CI, 1.34–1.43).


• Men with a high baseline risk of skeletal complications developed more fractures after ADT.

• The mortality risk is 40% higher after experiencing a fracture.

• Consideration of patient risk before prescribing ADT for long-term use may reduce both fracture risk and fracture-associated mortality.
