The role of frailty in modifying physical function and quality of life over time in older men with metastatic castration-resistant prostate cancer.

Among older men receiving care for mCRPC, frailty may be associated with worse baseline QoL and PF, but over time, frail patients may experience largely similar trends in QoL and PF as their non-frail counterparts. Further study with larger sample size and longer follow-up may help elucidate how best to incorporate frailty into treatment decision-making for mCRPC.
