Objective To report the first systematic investigation of the cognitive effects of luteinizing hormone-releasing hormone (LHRH) analogues in male patients, as LHRH analogues have been associated with memory impairments in women using these drugs for gynaecological conditions. Patients and methods Eighty-two men with extraprostatic prostate cancer were randomly assigned to receive either continuous leuprorelin, goserelin (both LHRH analogues), cyproterone acetate (a steroidal antiandrogen) or close clinical monitoring. These patients underwent cognitive assessments at baseline and before starting treatment (77), and then 6 months later (65).Results Compared with the baseline assessments, men receiving androgen suppression monotherapy performed worse in two of 12 tests of attention and memory; 24 of 50 men randomized to active treatment and assessed 6 months later had a clinically significant decline in one or more cognitive tests but not one patient randomized to close monitoring showed a decline in any test performance. Conclusion Pharmacological androgen suppression monotherapy for prostate cancer may be associated with impaired memory, attention and executive functions.

from university teaching hospitals. All those with prostate cancer who were eligible for hormonal therapy had no symptoms requiring immediate therapy. In all, 82 patients were randomized and 62 completed the 1-year study, and of the 20 community participants, 15 completed the study. The main outcome measures were obtained from questionnaires on emotional distress, existential satisfaction, physical function and symptoms, social and role function, subjective cognitive function, and sexual function, combined with standard neuropsychological tests of memory, attention, and executive functions. RESULTSSexual dysfunction increased for patients on androgen-suppressing therapies, and emotional distress increased in those assigned to CPA or close clinical monitoring. Compared with before treatment there was evidence of an adverse effect of leuprorelin, goserelin, and CPA on cognitive function. CONCLUSIONSIn deciding the timing of androgen suppression therapy for prostate cancer, consideration should be given to potential adverse effects on quality of life and cognitive function. KEYWORDSprostate cancer, LHRH analogues, cyproterone acetate, quality of life, cognition, memory OBJECTIVESTo investigate the effects of different management strategies for non-localized prostate cancer on men's quality of life and cognitive functioning. PATIENTS, SUBJECTS AND METHODSMen with prostate cancer were randomly assigned to one of four treatment arms: leuprorelin, goserelin, cyproterone acetate (CPA), or close clinical monitoring. In a repeated-measures design, men were assessed before treatment (baseline) and after 6 and 12 months of treatment. A community comparison group of men of the same age with no prostate cancer participated for the same length of time. The men were recruited from public and private urology departments

Prostatic carcinoma and its treatment have been associated with adverse effects on health‐related quality of life (HRQoL). Individual differences in appraisal and coping have been suggested to mediate these HRQoL outcomes. A randomized trial of 65 men with non‐localized prostate cancer compared several treatments and tested associations between appraisal, coping, and HRQoL. These patients, and 16 community volunteers matched for age and general health, undertook psychosocial assessments before treatment and after 6 months of treatment. Compared with baseline assessments, men on hormonal treatments reported impaired sexual function. Groups did not differ on emotional distress, existential satisfaction, subjective cognitive function, physical symptoms, or social and role functioning. For individuals, hormonal treatments were more frequently associated with decreased sexual, social and role functioning, but were also associated with improved physical symptoms. In hierarchical regression analysis, HRQoL was lower for men who had more comorbid illnesses, a history of neurological dysfunction, higher threat appraisals, or higher use of coping strategies at baseline. These results showed that pharmacological hormonal ablation for prostate cancer can improve or decrease HRQoL in different domains. HRQoL in men with prostate cancer was associated more strongly with appraisal and coping than with medical variables. Copyright © 2002 John Wiley & Sons, Ltd.
