Every Week, the Editor-in-Chief selects an Article of the Week from the current issue of BJUI. The abstract is reproduced below and you can click on the button to read the full article, which is freely available to all readers for at least 30 days from the time of this post.

In addition to the article itself, there is an accompanying editorial written by a prominent member of the urological community. This blog is intended to provoke comment and discussion and we invite you to use the comment tools at the bottom of each post to join the conversation.

If you only have time to read one article this month, it should be this one.

To assess bone‐density testing (BDT) use amongst prostate cancer survivors receiving androgen‐deprivation therapy (ADT), and downstream implications for osteoporosis and fracture diagnoses, as well as pharmacological osteoporosis treatment in a national integrated delivery system.

Patients and methods

We identified 17 017 men with prostate cancer who received any ADT between 2005 and 2014 using the Veterans Health Administration cancer registry and administrative data. We identified claims for BDT within a 3‐year period of ADT initiation. We then used multivariable regression to examine the association between BDT use and incident osteoporosis, fracture, and use of pharmacological treatment.


We found that a minority of patients received BDT (n = 2 502, 15%); however, the rate of testing increased to >20% by the end of the study period. Men receiving BDT were older at diagnosis and had higher‐risk prostate cancer (both P < 0.001). Osteoporosis and fracture diagnoses, use of vitamin D ± calcium, and bisphosphonates were all more common in men who received BDT. After adjustment, BDT, and to a lesser degree ≥2 years of ADT, were both independently associated with incident osteoporosis, fracture, and osteoporosis treatment.


BDT is rare amongst patients with prostate cancer treated with ADT in this integrated delivery system. However, BDT was associated with substantially increased treatment of osteoporosis indicating an underappreciated burden of osteoporosis amongst prostate cancer survivors initiating ADT. Optimising BDT use and osteoporosis management in this at‐risk population appears warranted.


Editorial: Low rates of bone density testing in prostate cancer survivors on androgen‐deprivation therapy: where do we go from here?

In this month’s issue of the BJU International, Kirk et al. 1 describe their findings regarding an important issue in the care of prostate cancer survivors on androgen‐deprivation therapy (ADT): the underuse of bone density testing (BDT) to screen for osteoporosis. ADT is the commonest systemic therapy in patients with prostate cancer, used in both metastatic and localised settings. Whilst it has clear survival benefits, ADT is also associated with harms including cardiovascular, cognitive, and metabolic side‐effects, as well as an increased risk of osteoporosis and fractures. These bone‐related complications are costly from a quality‐of‐life and financial perspective, especially given the critical importance of mobility in maintaining performance status and cardiovascular health during cancer treatment 23. Consequently, most clinical practice guidelines include osteoporosis screening as a recommendation for men undergoing ADT.

In their study, ‘The implications of baseline bone health assessment at initiation of androgen‐deprivation therapy for prostate cancer’, the authors describe patterns of use of BDT and diagnosis of osteoporosis amongst men treated for prostate cancer in the USA Veterans Affairs (VA) system within a 3‐year period following ADT initiation. There was a statistically significant increase in the BDT rate throughout the study period; however, overall BDT remains uncommon amongst patients with prostate cancer on ADT, used in only 15% of men in their cohort. Unsurprisingly, patients who received BDT were more likely to be diagnosed with osteoporosis, be diagnosed with a fracture, and receive treatment with vitamin D, calcium and bisphosphonates. The authors acknowledge an important limitation about the applicability of their VA study to the civilian health population. However, given that the VA and military health systems perform as well, if not better, on several important metrics in prostate cancer care 45, these results should not be ignored simply because they were obtained in the military health system.

The increase in BDT screening throughout the study may be attributable to increased awareness of guidelines published during the study period. However, the overall BDT rate remains low. This may be explained by insufficient access, lack of information technology, as well as more nebulous aspects of care such as physician culture, beliefs, and habits 6.

Studies such as this are vital to identify opportunities for improving care delivery. What are needed next are innovations to optimise the delivery of care for patients treated with ADT. Whilst improving BDT adherence may lack the cachet of next‐generation targeted therapies, this is an example of the kind of simple, measurable area where improvement in care delivery systems may yield large benefits.

There are many possible avenues for success: quality improvement collaboratives are one well‐known innovation, which may be applicable to this area: examples, such as the Michigan Urological Surgery Improvement Collaborative (MUSIC) and the AUA Quality Registry (AQUA) are success stories, but to our knowledge there are no published studies specifically attempting to improve adherence to BDT guidelines within these cohorts. Other practice‐based innovations include navigators and multidisciplinary cancer teams, either of which may yield improvements in guideline adherence. Online patient support groups can raise awareness. And although we all know how electronic reminders have frustrated countless physicians, electronic reminders about recommended tests and interventions may be an important tool. At our institution, a Prostate Cancer Foundation grant is funding the development of a mobile health app, which is targeted exclusively at men receiving ADT for prostate cancer. This app will encourage physical activity and healthy eating, which can both support bone health.

In our view, the issue of bone screening is a clear example of where innovative strategies to improve care delivery and guideline adherence may make a big difference for men living with prostate cancer. We look forward to seeing more in the years to come.
