Systemic Therapies

289 Background: Patients with metastatic prostate cancer receive several therapies which may be associated with a tendency to overweight and impaired glucose tolerance. These include androgen deprivation therapy and long term steroid therapy. We set out to assess the prevalence of overweight and diabetes/prediabetes in a cohort of patients attending an oncology day ward for a variety of systemic therapies. Methods: We performed a retrospective review of the medical records of men attending an oncology day ward for prostate cancer treatment. As part of their usual care, these men had regular height and weight checks and also had periodic hemoglobin A1C (HbA1C) measurements performed. The prevalence of prediabetes and diabetes in this patient population was assessed from the HbA1C results using the American Diabetes Association 2016 definitions. Information on patient steroid use (and type), and treatment type were also recorded. Results: Among 34 men with metastatic prostate cancer, the mean age was 74 (range 57-88). Therapies received included androgen deprivation therapy in all cases, with chemotherapy or novel androgen receptor pathway inhibitors such as abiraterone and enzalutamide. Only 12% had a pre-existing diagnosis of diabetes mellitus (all type 2). The majority (79%) are overweight or obese. 59% have pre-diabetes as per the American Diabetes Association 2016 Guidelines, while a further 24% meet criteria for diabetes. Only 18% have HbA1c in the normal range. 56% are on continuous long term steroid therapy, usually as part of their prostate cancer therapy. A further 23% receive intermittent steroids. Only 21% had received no steroids in the 6 months prior to first HbA1C check. 18% had castrate-sensitive disease and 82% had castrate resistant disease. Even among patients with castrate sensitive disease, 2/3 had abnormal HbA1c values. Conclusions: Overweight and prediabetes are very prevalent in men receiving systemic therapies for metastatic prostate cancer. A large percentage of men are on long-term steroid therapy which may be contributing to their risk of these conditions. Intervention is required for this group of patients to reduce the impact of therapy on cardiovascular and overall health.

The Impact

Background: While semiannual 60 mg denosumab is a common treatment for osteoporosis, impact of monthly 120 mg denosumab, the common treatment protocol for bone metastases from solid tumors, on bone metabolism is unclear.Materials and Methods: We reviewed 15 patients with bone-metastatic prostate cancer who initiated monthly 120 mg denosumab in conjunction with androgen deprivation therapy between 2013 and 2014. Bone mineral density (BMD) was measured at lumbar spine and femoral neck using dual energy X-ray absorptiometry (DXA), before treatment and annually thereafter. Bone metabolism markers, including urine N-terminal telopeptide (uNTx) and bone type alkaline phosphatase (BAP), were monitored monthly.Results: Twelve of 15 (80%) patients had evaluable DXA before treatment, and of them, eight underwent DXA after a year of initiation without discontinuation of denosumab. Percent changes in BMD from baseline were +6.2% at lumbar spine and +7.6% at femoral neck, both of which were significant increases (both P<0.01). Bone metabolism markers were evaluable in 11 (73%) patients: uNTx decreased rapidly, while BAP declined gradually after initiating denosumab. These effects were similar to those seen by the standardized dose for osteoporosis in previous literature. There were no denosumab-related severe adverse events during the follow-up period. Conclusions: The impact of monthly 120 mg denosumab on bone metabolism was significant, but almost equivalent to that of the standard dose for osteoporosis (60mg semiannually) in bone-metastatic prostate cancer undergoing androgen deprivation therapy. Whereas the higher dose has reportedly reduced skeleton-related events, the effect on bone metabolism seemed plateaued or showed no dose-dependency.
