    ABSTRACT: The impact of bicalutamide (Casodex) monotherapy on bone mineral density (BMD) was investigated in patients with locally advanced prostate cancer. BMD was assessed after treatment with bicalutamide 150 mg daily ( n=21) or by medical castration (goserelin acetate 3.6 mg every 28 days) ( n=8) for a median of 287 weeks. In 38% of castration compared with 17% of bicalutamide patients, femoral neck Z-scores were < or =-1 SD of the reference value (accepted as a two to three times increased risk of fracture) and T-scores were < or =-2.5 SD (World Health Organization definition of osteoporosis in white females). Total hip Z-scores were < or =-1 in 43% of castration patients and 13% of bicalutamide patients. In 38% of patients, lumbar spine BMD was affected by degenerative disease. These preliminary data suggest that there may be an advantage in terms of BMD in using bicalutamide monotherapy compared with castration; a benefit confirmed in a recent prospective randomised study.

    ABSTRACT: Nonsteroidal antiandrogen monotherapy may be a treatment option for some patients with advanced prostate cancer. We report a survival and safety update from an analysis of 2 studies in which patients with nonmetastatic (M0) locally advanced disease were treated with either 150 mg. bicalutamide monotherapy or castration. Data from 2 open label, multicenter studies of identical design were pooled according to protocol. Patients with stage T3/4 prostate cancer were randomized to receive 150 mg. bicalutamide daily or castration (orchiectomy or 3.6 mg. goserelin acetate every 28 days) in a 2:1 ratio. A total of 480 patients with locally advanced prostate cancer were randomized to treatment. After a median followup of 6.3 years mortality was 56%. There was no statistically significant difference between the 2 groups in overall survival (hazard ratio 1.05, upper 1-sided 95% confidence limit 1.31, p = 0.70) or time to progression (1.20, 1.45, p = 0.11). There were statistically significant benefits in the bicalutamide monotherapy group in the 2 quality of life parameters of sexual interest (p = 0.029) and physical capacity (p = 0.046). The highest incidences of adverse events were the pharmacological side effects of hot flashes in the castration group, and breast pain and gynecomastia in the bicalutamide group. The incidences of other types of adverse events were low. Bicalutamide was well tolerated, with few drug related withdrawals from study, and no new safety issues were identified during this longer followup. Monotherapy with 150 mg. bicalutamide is an attractive alternative to castration in patients with locally advanced prostate cancer for whom immediate hormone therapy is indicated.

    ABSTRACT: The introduction of prostate specific antigen (PSA) testing has revolutionised the early detection, management and follow-up of patients with prostate cancer and it is considered to be one of the best biomedical markers currently available in the field of oncology. Its use with annual digital rectal examination in prostate cancer screening programmes has led to a marked change in the distribution of stage at presentation towards earlier disease and led to a significant increase in the detection of potentially curable disease. In order to improve the specificity of PSA testing and thereby reduce the number of unnecessary prostatic biopsies, a number of refinements of PSA evaluation have been proposed. These include free to total PSA ratio, PSA density, PSA density, PSA density of the transition zone, PSA velocity and age-specific PSA reference ranges. The utility of these approaches is considered in this review. The role of PSA monitoring in the detection of recurrence following radical prostatectomy and radiotherapy is discussed, as well as its role in monitoring patients treated with endocrine therapy is discussed, as well as its role in monitoring patients treated with endocrine therapy in terms of correlating PSA response with outcome, in detecting disease progression and in guiding the use of subsequent therapies. Large continuing multicentre screening and outcome studies will provide important information enabling greater refinement of the use of this important diagnostic and monitoring tool in the future detection and management of prostate cancer.
