2、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 only.,AUA(2010)内分泌治疗新进展,METHODS In

3、 this French multicenter, open, randomised trial, patients less than 80 years, with histologically confirmed PCa, T3-4, or pT3 (biopsy) N0M0 were included. They were centrally randomised in 2 parallel groups to either ADT alone (leuprorelin 11.25 mg SR,1 sc injection every 3 months for 3 years or th

5、NTRODUCTION AND OBJECTIVES Cardiovascular mortality is the most important cause of death in patients with prostate cancer (PC). The development of metabolic syndrome (MS) in patients undergoing androgen deprivation therapy (ADT) has been related with this increase in mortality rate. The aim of this

6、study has been to confirm the hypothesis that ADT increases the prevalence of MS.,AUA(2010)内分泌治疗新进展,METHODS A group of 157 patients were enrolled in this interim analysis of a prospective case control study. 53 PC patients under ADT during a mean time of 52 months (6 to 252) and 104 age matched cont

7、rols evaluated at the time of prostate biopsy (52 with cancer and 52 without) were included.,AUA(2010)内分泌治疗新进展,METHODS MS was analyzed according the ATPIII panel criteria: Fasting plasma glucose level 110 mg/dL serum triglyceride level 150 mg/dL serum high-density lipoprotein level102 cm Blood press

8、ure of 130/85 mmHg.,AUA(2010)内分泌治疗新进展,RESULTS MS was diagnosed in 27 of the 53 patients subjected to ADT (51.9%) while it was detected in 35 of the 105 age-matched controls (33.3%), p = 0.020. However the prevalence of MS was 35.8% (19/53) in men without PC and 30.8% (16/52) in men with PC, p=0.365.

9、,AUA(2010)内分泌治疗新进展,CONCLUSION Although the limited number cases and controls included in this interim analysis, a significant increase in the prevalence of MS was observed in PC patients subjected to ADT.,AUA(2010)内分泌治疗新进展,Metabolic change after androgen deprivation therapy in Korean men with prosta

10、te cancer Chang Hoo Park, Korea,AUA(2010)内分泌治疗新进展,INTRODUCTION AND OBJECTIVES In 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 c

11、hanges in fat thickness, bone mineral density (BMD), body mass index (BMI), and levels of hemoglobin (Hb) and cholesterol. We also compared them with data from healthy subjects.,AUA(2010)内分泌治疗新进展,METHODS From December 2002 to December 2008, 148 Korean men treated with leuprolide depot and bicalutami

12、de for prostate cancer and 100 healthy subjects were investigated included change from baseline to month 12 in fat thickness, bone mineral density (BMD), body mass index (BMI), and levels of hemoglobin (Hb) and cholesterol.,AUA(2010)内分泌治疗新进展,RESULTS,There are no significant changes in hemoglobin and

13、 cholesterol levels.,AUA(2010)内分泌治疗新进展,CONCLUSION Our results show that Korean men with prostate cancer have increased abdominal subcutaneous fat and BMI and have decreased BMD during androgen deprivation therapy. These increases the risk of bone fracture and complication related obesity. Therefore,

14、 BMD will be checked periodically and carry out exercise program to prevention obesity during androgen deprivation therapy.,AUA(2010)内分泌治疗新进展,Sarcopenia in men receiving androgen deprivation therapy for prostate cancer: a prospective 3-year study. Matthew R. Smith,CA.,AUA(2010)内分泌治疗新进展,INTRODUCTION

15、AND OBJECTIVES Androgen deprivation therapy (ADT) for prostate cancer decreases bone mineral density and increases 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 repor

16、t the prospective changes in LBM in a subset of men from that study.,AUA(2010)内分泌治疗新进展,METHODS Men 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

17、 least 1 on-study LBM result were considered evaluable and included in this analysis.,AUA(2010)内分泌治疗新进展,METHODS Subjects were stratified at baseline by age (6 months). LBM was measured by total body dual-energy x-ray absorptiometry at baseline and at 12, 24, and 36 months.,AUA(2010)内分泌治疗新进展,RESULTS

18、From baseline to month 12, mean LBM decreased significantly by 1.0% (p=.0004). Significant decreases in LBM were also observed at month 24 (2.1%, p.0001) and month 36 (2.4%, p.0001).,AUA(2010)内分泌治疗新进展,RESULTS Men aged 70 years(n=127) had significantly greater changes in LBM at all measured time poin

19、ts. At 36 months, LBM decreased by 2.8% in men aged 70 years compared with a decrease of 0.9% in younger men (p=0.035).,AUA(2010)内分泌治疗新进展,CONCLUSION This is the largest and longest prospective study undertaken to describe the natural history of muscle loss in men undergoing ADT therapy for prostate

20、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(2010)内分泌治疗新进展,Recovery of testosterone and PSA after cessation of long term luteinizing hormone releasing hormone agonist (LHRH) th

21、erapy for prostate cancer: a prospective trial.

However, many questions remain regardi

22、ng timing of initiation, and length of treatment interval for medically induced castration.,AUA(2010)内分泌治疗新进展,INTRODUCTION AND OBJECTIVES The effects of long term LHRH agonist on the hypothymalic pituitary gonadal axis are also not completely understood. We sought to examine the effects of long term

23、 LHRH agonist on recovery of testosterone and PSA.,AUA(2010)内分泌治疗新进展,METHODS Hormonal ablation was discontinued and serial testosterone and PSA measurements were obtained on a three monthly basis. Patients were counseled regarding restarting hormonal therapy if 2 consecutive rises in PSA were observ

24、ed. Patients were allowed to stay off hormones and on study if they desired.,AUA(2010)内分泌治疗新进展,METHODS We organized a prospective trial examining men at the Veterans Administration Hospital who had been on at least 48 months of an LHRH agonist. Other inclusion criteria were that PSA be less than 3ng

25、/ml, and not rising for the 2 consecutive values prior to discontinuing hormones.,AUA(2010)内分泌治疗新进展,RESULTS Nineteen patients were enrolled in the study between 2007 and 2008. The mean age was 75 years. The mean duration of hormonal therapy was 88 months.,AUA(2010)内分泌治疗新进展,RESULTS Ten (53%) patients

26、 were on hormones for biochemical recurrence; Two (10%) for metastatic disease; Seven (36%) as primary therapy.,AUA(2010)内分泌治疗新进展,RESULTS Eleven (58%) patients had 2 consecutive rises in PSA; The mean time to see two consecutive rises was 11 months.,AUA(2010)内分泌治疗新进展,RESULTS The mean time off therap

27、y prior to a rise in PSA 0.1ng/ml above base line for all patients and those with 2 consecutive rises was 15.4 and 9.5 months respectively. The mean base line PSA, mean PSA at one, and at two years off therapy was 0.3ng/ml, 1.1ng/ml, and 5ng/ml respectively. Mean testosterone at base line, one, and

28、two years off therapy was 13.9ng/ml, 76ng/ml, and 150.6ng/ml respectively.,AUA(2010)内分泌治疗新进展,RESULTS Twelve (63%) patients had recovery of testosterone above 50ng/dl. Four (21%) patients remained castrate off therapy a mean of 20 months. The mean time to testosterone recovery was 12.8 months. Two (10.5%) patients in the study have died. One death was attributed to prostate cancer.,AUA(2010)内分泌治疗新进展,CONCLUSION The recovery of testosterone and significant elevations of PSA after long term LHRH agonist therapy is significantly delayed in most patients.
