RESUMO

PURPOSE: Compare the efficacy and tolerability of dutasteride in combination with bicalutamide to bicalutamide monotherapy in the treatment of locally advanced and metastatic prostate cancer (PCa). METHODS: One-hundred-fifty PCa patients with locally advanced or metastatic disease were prospectively enrolled and randomly assigned to receive either bicalutamide monotherapy 150 mg once daily (79 patients) or bicalutamide 150 mg plus dutasteride 0.5 mg once daily (71 patients). Treatment response was assessed by serum PSA level measurement, and standard procedures for diagnosis of clinical progression were used during follow-up. Patient-reported quality of life (QoL) was assessed using validated questionnaires (EORTC QLQ-C30 and QLQ-PR25). RESULTS: At 3 years follow-up, PSA progression was found in 52 patients [65.8 %; 95 % confidence interval (CI) 55.4-76.3] in the monotherapy group compared to 38 patients (53.5 %; 95 % CI 41.9-65.1) in the combined therapy group (p = 0.134). At the time of analysis 37 men (46.8 %; 95 % CI 35.8-57.8) in the monotherapy group had died versus 30 men (42.3 %; 95 % CI 30.8-53.7) in the combined therapy group. Median survival time was 5.4 and 5.8 years, respectively (p = 0.694). There was no statistically significant difference in the presentation frequency of adverse events between groups (p = 0.683). QoL was good and comparable between the two groups. CONCLUSIONS: Both therapies were well tolerated with a good QoL. However, despite a trend toward higher efficacy of the combined therapy, progression-free survival and overall survival was not significantly different between the groups. Further research on this therapy should be performed.

RESUMO

OBJECTIVES: In muscle invasive bladder cancer (MIBC), careful clinical staging is essential for patient counseling and decision-making. Bimanual palpation (BP) is an integral part and guideline advice of clinical staging. Until now, however, the value of BP has never been studied. With this study, we aim to determine the accuracy of clinical staging through BP. METHODS: Detailed clinical data were collected from a population-based series of 1,409 patients with MIBC, diagnosed between 1989 and 2005, in the region of the Comprehensive Cancer Centre East in The Netherlands. Selected were all patients who underwent BP (n = 738). Preoperative tumor-stage (cT-stage) determined through BP was compared with post-cystectomy pT-stage. Contingency tables were made to determine the correlation between cT-stage and pT-stage. RESULTS: In 18 of 142 patients in whom BP showed an organ-confined tumor, the tumor was unresectable (pT4) at the time of surgery. Four out of 9 patients who had a suspected T4 tumor on BP but who underwent cystectomy anyway appeared to have operable tumors at cystectomy. In 87 patients (57.6%), accurate staging through BP was observed. In 17 patients (11.3%), clinical overstaging was found, and in 47 patients, (31.1%) clinical understaging. CONCLUSIONS: Frequently, pT-stage after cystectomy does not correlate with preoperative cT-stage based on BP. Discrepancy was observed in 42% of the patients: in 11%, clinical overstaging and in 31%, clinical understaging. Based on these data, some caution is suggested when interpreting the outcome of BP. Prospective data is needed for a more formal evaluation of the staging accuracy of BP.
