2、JECTIVESIn locally advanced disease, the combination of radiotherapy (RT) and androgen deprivation (ADT) is superior to RT alone.But ADT with an analogue has never been compared to combined modality.We report a phase III randomised trial in locally advanced PCa, comparing a combined modality and ADT

8、(2019)内分泌治疗新进展INTRODUCTION AND OBJECTIVESIn men with prostate cancer, Androgen deprivation therapy shows a variety well recognized metabolic alteration.To better characterize the metabolic effects of androgen deprivation therapy in Korean men, we evaluated the changes in fat thickness, bone mineral

We also compared them with data from healthy subjects.AUA(2019)内分泌治疗新进展INTRODUCTION AUA(2019)内分泌治疗新进展METHODSFrom December 2019 to December 2019, 148 Korean men treated with leuprolide depot and bicalutamide for pros

14、ncreases fracture risk.Studies with limited sample size and observational periods have reported that ADT is also associated with sarcopenia or loss of muscle (lean body mass, LBM). We now report the prospective changes in LBM in a subset of men from that study.AUA(2019)内分泌治疗新进展INTRODUCTION AUA(2019)

15、内分泌治疗新进展METHODSMen undergoing ADT for nonmetastatic prostate cancer at 38 centers in North America were randomized to denosumab or placebo.A total of 248 subjects (130 denosumab, 118 placebo) with a baseline and with at least 1 on-study LBM result were considered evaluable and included in this analy

LBM was measured by total body dual-energy x-ray absorptiometry at baseline and at 12, 24, and 36 months. AUA(2019)内分泌治疗新进展METHODSAUA(2019)内分泌治疗新进展RESULTSFrom baseline to month 12, mean LBM d

AUA(2019)内分泌治疗新进展RESULTSAUA(2019)内分泌治疗新进展RESULTSMen aged 70 years(n=127) had significantly greater changes in LBM at all measured time points. At 36 month

AUA(2019)内分泌治疗新进展RESULTSAUA(2019)内分泌治疗新进展CONCLUSIONThis is the largest and longest prospective study undertaken to describe the natural history of muscle loss in men undergoing ADT therapy for pr

19、ostate cancer. LBM significantly decreased at 12, 24, and 36 months. Decreases in LBM were greatest in older men and in those who had short duration of ADT at study entry.AUA(2019)内分泌治疗新进展CONCLUSIONAUA(2019)内分泌治疗新进展Recovery of testosterone and PSA after cessation of long term luteinizing hormone rel

23、 basis. Patients were counseled regarding restarting hormonal therapy if 2 consecutive rises in PSA were observed. Patients were allowed to stay off hormones and on study if they desired.AUA(2019)内分泌治疗新进展METHODSAUA(2019)内分泌治疗新进展METHODSWe organized a prospective trial examining men at the Veterans Ad

24、ministration Hospital who had been on at least 48 months of an LHRH agonist. Other inclusion criteria were that PSA be less than 3ng/ml, and not rising for the 2 consecutive values prior to discontinuing hormones.AUA(2019)内分泌治疗新进展METHODSAUA(2019)内分泌治疗新进展RESULTSNineteen patients were enrolled in the

This helps to support the concept of intermittent androgen ablation which has benefits in quality of life and reduced cost of therapy.
