Journal of UrologyFebruary 1997 Osteoporosis after Orchiectomy for Prostate Cancer Harry W Daniell UC Davis, Department of Family Practice First article attributing orchiectomy with accelerated osteoporosis and questions risks to long term survivors.
ADT Is Associated With Fracture ADT-Related Fracture-Free Survival • In men surviving at least 5 years after diagnosis: • Of those receiving ADT, 19.4% experienced a fracture • Of those NOT receiving ADT, 12.6% experienced a fracture • ADT resulted in an excess risk of fracture of 45% 100 90 80 70 60 Unadjusted Fracture-Free Survival (%) 50 40 No ADT (n = 32,931)GnRH agonist, 1–4 doses (n = 3763)GnRH agonist, 5–8 doses (n = 2171)GnRH agonist, ≥ 9 doses (n = 5061)Orchiectomy (n = 3399) 30 20 10 0 1 2 3 4 5 6 7 8 9 10 Years After Diagnosis ShahinianVB, et al.

Bone Clinic Protocol • 1. All patients on ADT seen by mid-level at least yearly • 2. All patients undergo DEXA • 3. All patients have metabolic studies • 4 All patients assessed/counseled for risk: FRAX,fall,glasses,smoking,EtOHconsumption,calcium/vitamin D
Screening for Bone Loss • DXA(Dual X-ray Absorptiometry) = Gold Standard • Total hip, femoral neck and lumbar spine standard areas of interest • Heel ultrasound, finger or forearm DXA, and quantitative CT other options but numerous weaknesses
Metabolic workup • CMP, CBC, Vitamin D minimum • Stone formers 24 hour urine • Options; TSH, evaluate for GI malabsorption, Endocrine consult
TREATMENT DECISION • 2 clinical trials with level 1 evidence of both BMD and fracture reduction • Patient population included men< 70 with osteopenia and >70 without regard to BMD • NOF recommends treat osteoporosis follow FRAX for others • What is risk level for osteopenics on ADT
Minimum treatment • Ensure adequate calcium/vitamin D intake 1200/800 • Vitamin D >30 • Reduce alcohol, smoking cessation, and weight bearing exercises • Fall reduction strategies
Pharmacologic Therapy • 1. Prolia-RANK ligand monoclonal antibody • 2. Aledronate(Fosamax).Risedronate(Actonel) • 2. Zoledronic acid(Zometa,Reclast) • 2.Raloxifene(Evista) • 3.? Teriparatide(Forteo) blackbox warning with radiation therapy • 3. Calcitonin(Miacalcin) no data in men
