ADT induces bone loss(ADTIBL)and muscle loss(sarcopenia)leading to falls and farctures. There are 2 aims in bone management of prostate cancer:one is to prevent fragility fractures in patients without bone metastasis and the other is to prevent symptomatic skeletal events(SSE)which are pathologic fractures, spinal compression, radiation to bones and surgery to bones. Bone fractures and SSE are both correlated with worse overall survival(OS). Concomitant use of novel anti-androgens further increases the risk of falls and fractures. The earlier and appropiriate intervention with vitamin D and bone modifying agents(BMA)is necessary to prevent treatment related bone fractures and SSE. Bone management algorithm aids to decide the timing and doses of BMA. As for sarcopenia physical exercise and life style advices are important. Because abiraterone with glucocorticoid therapy induces stronger bone resorption, it is recommended to start denosumab simultaneously.
