摘要
Objective To investigate the association between androgen-deprivation therapy (ADT) and fracture risk in men with prostate cancer in England. Patients and Methods Using the Hospital Episodes Statistics database, which contains all the information about National Health Service (NHS) and NHS-funded hospital admissions in England, for the years 2004-2008, 8 902 patients were found to have had prostate cancer and an admission to hospital with a fracture. Of these patients, 3 372 (37.8%) were identified as being treated with ADT, whilst 5 530 (62.2%) were not. There was a total of 228 852 admissions in the background population. Results The risk of a fracture requiring hospitalisation increased from 1.12 to 1.41 per 100 person-years in a man with prostate cancer treated with ADT compared with those without ADT, an absolute increase of only 0.29 per 100 person-years. When compared with the background population, there was an increase from 0.58 to 1.41 per 100 person-years, a relative rate ratio increase of 2.4 (P < 0.01) with an absolute increase of 0.83 per 100 person-years. Conclusion In England there was a small but statistically significant increased risk of fracture in men who had been treated with ADT. Men with prostate cancer, with or without ADT, were at an increased risk of fracture compared with the background population. We therefore suggest that if bone health is to be taken seriously in men with prostate cancer that all these men should be risk assessed (FRAX (R) or Qfracture (R) tools, as National Institute for Health and Care Excellence advised), as all men with prostate cancer have an increased risk of fracture, with those on ADT having slightly higher risk.
