抑那通3.75mg预充式注射器 AUA(2010)内分泌治疗新进展 RESULTS The mean time off therapy 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 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. This helps to support the concept of intermittent androgen ablation which has benefits in quality of life and reduced cost of therapy.
