RESUMO

OBJECTIVES: The first summary of the European Association of Urology (EAU) guidelines on prostate cancer was published in 2001. These guidelines have been continuously updated since many important changes affecting the clinical management of patients with prostate cancer have occurred over the past years. The aim of this paper is to present a summary of the 2005 update of the EAU guidelines on prostate cancer. METHODS: A literature review of the new data has been performed by the working panel. The guidelines have been updated and level of evidence/grade of recommendation added to the text. This enables readers to better understand the quality of the data forming the basis of the recommendations. RESULTS: A full version is available at the EAU Office or at . Systemic prostate biopsies under ultrasound guidance is the preferred diagnostic method and the use of periprostatic injection of a local anaesthetic can significantly reduce pain/discomfort associated with the procedure. Active treatment (surgery or radiation) is mostly recommended for patients with localized disease and a long life expectancy with radical prostatectomy being the only treatment evaluated in a randomized controlled trial. Follow-up is at large based on prostate specific antigen (PSA) and a disease-specific history with imaging only indicated when symptoms occur. Cytotoxic therapy has become an option for selected patients with hormone refractory prostate cancer. CONCLUSION: The knowledge in the field of prostate cancer is rapidly changing. These EAU guidelines on prostate cancer summarize the most recent findings and put them into clinical practice.

RESUMO

OBJECTIVE: To evaluate how an increasing burden of symptoms influences well-being, anxiety and depression at different intervals after a radical cystectomy with urostomy for bladder cancer, as this therapy can induce long-term distressful symptoms. PATIENTS AND METHODS: Patients with bladder cancer undergoing radical cystectomy in Stockholm between 1969 and 1995 were matched with 434 controls from the normal population; all 404 patients operated on between 1985 and 1995 at three other hospitals in Sweden were invited to enter the study. The final analysis included 306 patients and 310 controls, all assessed for symptoms and well-being. RESULTS: A low or moderate level of well-being was reported by 35% of the patients having none or one of the symptoms studied, by 39% with two symptoms, by 45% with three symptoms and by 66% of those with four or more symptoms. The values, irrespective of symptom burden, were 45% after 2-5 years of follow-up, 58% after 6-10 years and 38% at>10 years after surgery. The total symptom burden also influenced the risk of anxiety and depression. Symptom prevalence remained largely unaffected by the duration of follow-up, except for defecation urgency. CONCLUSIONS: The number of long-term symptoms after radical surgery with a urostomy for urinary bladder cancer affects the risk of anxiety, depression and low or moderate well-being.

RESUMO

OBJECTIVE: To report the initial results from Sweden of a large population-based randomized study of screening using prostate-specific antigen (PSA) to detect prostate cancer, as the efficacy of such screening to decrease prostate cancer mortality has not yet been proven. METHODS: From the population registry men aged 50-66 years were randomized to screening (9973) and to future controls (9973). Men randomized to screening were invited to have their serum measured for free PSA (fPSA) and total PSA (tPSA) in serum using the Prostatus f/tPSA assay (Perkin-Elmer, Turku, Finland). Men with a tPSA of < 3.0 ng/mL were not further investigated, while those with a tPSA of > or = 3.0 ng/mL were investigated with a digital rectal examination (DRE), transrectal ultrasonography (TRUS) and sextant biopsies. RESULTS: Of those invited, 60% accepted PSA testing and 11.3% had a tPSA of > or = 3.0 ng/mL. Altogether 145 cancers were detected (positive predictive value, PPV, 24%); none were stage M1, two were stage N+ and 10 stage T3-4. Most (59%) cancers were impalpable and 39% were both impalpable and invisible on TRUS. At biopsy, 7% were Gleason score 2-4, 71% 5-6, 19% 7 and 2% Gleason score 8-10. A threshold tPSA of > or = 4.0 ng/mL would have detected 109 cancers in 366 biopsied men (PPV 30%) while cancer detection would have been 14% higher with a PPV of 36% using a threshold tPSA of > or = 3.0 ng/mL combined with a f/tPSA threshold of < or = 18%. CONCLUSIONS: PSA screening detects early-stage low-grade prostate cancer. Both the sensitivity and specificity can be increased by incorporating f/tPSA with a tPSA threshold of < 4 ng/mL.

RESUMO

OBJECTIVE: To describe the outcome, assessed as the level of prostate specific antigen (PSA), of a mature (more than half the events recorded) prospective randomized study with a median follow-up of 82 months of neoadjuvant hormonal therapy before radical prostatectomy, as this has been suggested to decrease the rate of positive surgical margins (i.e. provide greater potential to completely excise the tumour). PATIENTS AND METHODS: From December 1991 to March 1994, 126 patients with clinically localized prostate cancer were randomized between direct radical prostatectomy or a 3-month course of a gonadotrophin-releasing hormone analogue before surgery. The patients were followed by PSA determinations and a value of > 0.5 ng/mL used to define progression. RESULTS: The incidence of positive surgical margins decreased from 45.5% to 23.6% (P = 0.016) with hormone treatment. Despite this there was no difference in PSA progression-free survival at the last follow-up; it was 51.5% for those undergoing radical prostatectomy only and 49.8% for those who received hormonal pretreatment (P = 0.588). CONCLUSIONS: Three months of neoadjuvant hormonal therapy before radical prostatectomy offers no benefit to the patient and cannot be recommended for routine clinical use.

RESUMO

OBJECTIVE: To describe and evaluate treatment alternatives for patients with clinical T3 prostate cancer. MATERIAL AND METHODS: Literature review with main focus on recent studies in order to include the impact of prostate specific antigen (PSA). The possibility of using neoadjuvant/adjuvant hormonal therapy in combination with surgery or radiation was assessed. Results were related to life expectancy, tumour grade and serum PSA. RESULTS: M and N-staging is mandatory before treatment with curative intent. Watchful waiting is an option for selected patients but early hormonal therapy seems to offer some survival advantages. Standard 65-70Gy external beam radiation is not sufficient for these patients with extracapsular disease but better results are obtained with dose-escalation (beyond 70Gy) and/or adjuvant hormonal therapy. Radical prostatectomy may be an option for patients with long life expectancy and "early" tumours, neoadjuvant hormonal withdrawal is of no proven value. CONCLUSIONS: Patients with a long life expectancy should not be denied treatment with curative intent solely based on the finding of extracapsular disease.

RESUMO

OBJECTIVES: To evaluate the concept of active monitoring only in the management of patients with prostate cancer. METHODS: Literature review. RESULTS: Active monitoring may be recommended in patients with stage T1a, well- and moderately-differentiated disease. Patients with a life expectancy exceeding 10 years are recommended re-evaluation with PSA, TRUS and biopsies of the residual prostate. This treatment is also indicated in patients with stage T1b-T2b, well- and moderately-differentiated tumours and a life expectancy of less than 10 years. Active monitoring is optional in patients with stage T1b-T2b, Gleason 2-4 prostate cancer and a life expectancy of 10-15 years. It is also optional in asymptomatic patients with locally advanced disease, stage T3-T4 which are well- and moderately-differentiated and have a short life expectancy. A very rare asymptomatic patient with M1 disease and the possibility of close follow-up may be offered active monitoring. CONCLUSIONS: Active monitoring is still a viable option for selected patients diagnosed with prostate cancer.

RESUMO

OBJECTIVES: To develop clinical guidelines for the management of patients with prostate cancer. METHODS: Guidelines were compiled by a working panel based on current literature following a literature review using MEDLINE. Already published structured analysis from national and international guidelines was used, and panel consensus was employed when literature evidence was absent or of poor quality. RESULTS: The full text of the guidelines is available through the EAU Central Office and the EAU website (www.uroweb.org). This article summarizes the main conclusions from the guidelines concerning the diagnosis and staging, treatment and follow-up of patients with prostate cancer. The diagnosis of prostate cancer should be based on histopathological or cytological examinations. N- and M-staging may be omitted in selected patients with a low serum prostate-specific antigen due to low risk of metastasis. Active treatment is warranted in most stages of prostate cancer but active monitoring is recommended for elderly patients with early stage tumours and is still optional in some other situations. Follow-up is based on a disease-specific history, serum-prostate-specific antigen supplemented by a digital rectal examination. Routine imaging is not necessary in asymptomatic patients. CONCLUSIONS: Prostate cancer is one of the most common malignancies in men. These guidelines have been drawn up to provide support in the management of this large group of patients.

RESUMO

OBJECTIVE: To investigate the prevalence and clinical importance of urological abnormalities in men with community-acquired febrile urinary tract infection (UTI). PATIENTS AND METHODS: In this prospective study, 85 men (median age 63 years, range 18--86) were followed for 1 year after an episode of febrile UTI. They were investigated by excretory urography, cysto-urethroscopy, uroflowmetry, digital rectal examination and measurement of postvoid residual urine volume by abdominal ultrasonography. RESULTS: The radiological examination of the upper urinary tract in 83 patients revealed 22 abnormal findings in 19 men. Relevant clinical abnormalities leading to surgical intervention were found in only one patient who had renal calyceal stones. The lower urinary tract investigation disclosed 46 findings in 35 men. In all, surgically correctable disorders were found in 20 patients, of whom 15 had previously unrecognized abnormalities. All patients who required surgery were identified either by a history of voiding difficulties, acute urinary retention at the time of infection, the presence of microscopic haematuria at follow-up after one month, or early recurrent symptomatic UTI. CONCLUSION: Routine imaging studies of the upper urinary tract seem dispensable in men with febrile UTI. To reveal abnormalities of clinical importance, any urological evaluation should primarily be focused on the lower urinary tract.

RESUMO

OBJECTIVE: Prostate cancer has its most frequent location in the posterior-lateral part of the gland. The aim of this study was to evaluate the cancer detection rate of six systemic prostate biopsies with mid lobar biopsies taken far laterally in the prostate. PATIENTS AND METHODS: A total of 692 patients (aged 50--66 years) enrolled in a screening study underwent prostate biopsies because of an elevated serum prostate-specific antigen (PSA; > or =3 ng/ml) level. The outcome of the biopsies was related to findings at digital rectal examination (DRE) and transrectal ultrasound (TRUS) and to the location within the prostate. RESULTS: Prostate cancer was detected in 164 patients. DRE and TRUS were suspicious of malignancy in 66 cases (40%) and 84 cases (51%), respectively. The two biopsies taken far laterally midlobar in the prostate detected as many as 83% of the cancers and when combined with two apical biopsies, 96% of all cancers were detected. CONCLUSION: At PSA screening in this age-group, only 57% of the prostate cancers detectable by sextant biopsies were palpable or visible at TRUS. Most of the cancers (96%) were detectable by only four systematic, carefully directed biopsies. In men with normal DRE, the two lateral midlobar biopsies should be taken first during the biopsy procedure.

RESUMO

The incidence of prostate cancer is increasing and, due to the use of PSA, more and more patients are diagnosed with localized disease. These patients may be offered treatment with the intent to cure. Traditionally, this has been either by radical prostatectomy or some form of radiation therapy. This article describes the minimally invasive method with permanent seed implantation. The procedure, indications, contraindications, side effects and results from the literature 28 patients have been treated so far with acceptable proximate side effects and reductions in serum-PSA as expected.

RESUMO

Neoadjuvant hormonal therapy (NHT) prior to radical prostatectomy or radiation therapy for clinically localized prostate cancer has regained interest in recent years but proof of its clinical benefit with respect to patient survival is still pending. We reviewed the literature regarding NHT in prostate cancer; only studies with a high evidence level were included for analysis. Five prospective randomized trials of NHT in radical prostatectomy-treated patients could be identified. Despite significantly lower numbers of positive surgical margins in the NHT group, prostate specific antigen failure rates were similar in the NHT group and the surgery only group. Data on disease-free and overall survival are not yet available. The two prospective randomized studies of NHT in radiation-treated patients could demonstrate better local control of the tumor in the NHT group. However, there was no difference in overall survival between the NHT arm and the radiation only arm. Future clinical research should consider type and duration of hormonal treatment and evaluate potential surrogate end points. To date, there is no hard evidence in favor of NHT prior to radical prostatectomy or external beam irradiation. NHT in prostate cancer should only be applied within controlled trials.

RESUMO

OBJECTIVE: This study involved transrectal ultrasound (TRUS) examination of the prostate and seminal vesicles in healthy males, for use as a reference. MATERIAL AND METHODS: A total of 125 men (aged 20-69 years) with no history or symptoms of urogenital disease underwent TRUS. Prostate size (both total and central gland), focal lesions such as calcifications, hyper- and hypoechoic areas, cysts, and size and lobulation of the seminal vesicles were noted and related to age. RESULTS: The prostate measured 19.2 +/- 4 cm3 and calcifications were found in 23.1% of men aged 20-29 years compared with 35.5 +/- 12.5 cm3 and 83% for men aged 60-69 years. Overall, hyperechoic areas were found in 59.2% of those examined, cysts in 16.8% and hypoechoic areas in about 11%, predominantly in the peripheral zone. Totally normal sonograms were seen in 29% of the men under the age of 40 and in 5% of the men aged 40 or older. CONCLUSIONS: TRUS examinations of healthy males are seldom without sonographic changes. This study provides the frequencies with which these changes occur in healthy males of various ages, all without urogenital symptoms, and may be used for future comparisons with different pathological conditions.

RESUMO

OBJECTIVE: To assess the risk of over-diagnosing and over-treating prostate cancer if population-based screening with serum prostate-specific antigen (PSA) is instituted. PATIENTS AND METHODS: From a serum bank stored in 1980, PSA was analysed in 658 men with no previously known prostate cancer from a well-defined cohort from Göteborg, Sweden (men born in 1913); the incidence of clinical prostate cancer was registered until 1995. From the same area, and with the same selection criteria, another cohort of 710 men born in 1930-31, who in 1995 accepted an invitation for PSA screening, was also analysed. RESULTS: Of men born in 1913, 18 (2.7%) had died from prostate cancer and the cumulative probability of being diagnosed with clinical prostate cancer was 11.1% (5.0% in those with a PSA level of < 3 ng/mL vs 32.9% in those with a PSA level of > 3 ng/mL, P < 0.01). The mean lead-time from increased PSA (> 3 ng/mL) to clinical diagnosis was 7 years. The prostate cancer detection rate in men born in 1930-31 was 4.4% (22% among those with increased PSA levels) and 30 of 31 detected cancers were clinically localized. CONCLUSIONS: Screening and sextant biopsies resulted in a lower detection rate (22%) than the cumulative risk of having clinical prostate cancer (33%) in men with increased PSA levels, indicating that under-diagnosis rather than over-diagnosis is the case at least with 'one-time' screening. Even if the stage distribution in screening-detected cancers seems promising (and thus may result in reduced mortality) it is notable that screening 67-year-old men will result in treatment a mean of 7 years before clinical symptoms occur and only one in four men anticipated to develop prostate cancer will die from the disease within 15 years. Large randomized screening trials seem mandatory to further explore the benefits and hazards of PSA screening.

RESUMO

INTRODUCTION: Prostate cancer is the leading malignancy in men today and an increase in detected localized prostate cancers is expected in the years to come. Even though radical prostatectomy is an effective treatment, it is associated with a considerable morbidity in some cases and efforts are made to provide minimally invasive alternative treatment options with equal efficacy but fewer side effects. METHODS: Cryosurgical ablation of the prostate (CSAP), brachytherapy, high-intensity focused ultrasound (HIFU) and radiofrequency interstitial tumor ablation (RITA) were evaluated after a literature review from a Medline Search (1966-1998). Furthermore, personal experience and latest data from the authors were taken into account. RESULTS: All alternative treatments nowadays make use of sophisticated technology, including the latest ultrasound devices for exact planning and monitoring of treatment, leading to increased safety compared to treatments in the 1960s and 1970s. Five-year results of CSAP show a PSA <1 ng/ml in 60% of cases whereas brachytherapy is able to achieve PSA <1 ng/ml in 80% of cases in a selected group. Recent outcome data come close to results of radical prostatectomy series. HIFU and RITA are promising new technologies that proved to be able to induce extensive necrosis, but the follow-up is too short to determine their definite places in the treatment of prostate cancer. CONCLUSION: Two alternative treatment options for localized prostate carcinoma, CSAP and brachytherapy, have been studied with a sufficient number of patients and an adequate follow-up. The overall results of brachytherapy are favorable when compared to CSAP and are in the same range as the outcome after radical prostatectomy. HIFU and RITA are relatively new techniques based on sophisticated technology that are very promising at present, but a longer follow-up is mandatory.

RESUMO

BACKGROUND: We studied the extent of neuroendocrine (NE) tumor cell differentiation and its relation to regressive changes in prostate cancer after 3-month hormonal treatment. METHODS: Radical prostatectomy specimens from 103 patients, randomized to 3-month neoadjuvant LH-RH-analogue treatment (neoadjuvant group) or to surgery alone (control group), were available for analysis. The effects of hormonal treatment in terms of positive surgical margins, the degree of histopathological changes, and tumor cell proliferation were evaluated in relation to NE-differentiation assessed with antibodies against chromogranin A (CGA). RESULTS: Both the number of CGA-positive cells/cm(2) (P < 0.003) and the proportion of NE-positive tumors (P = 0.07) were greater in the neoadjuvant group than in the control group. No correlation existed between NE-differentiation and the effects of the neoadjuvant hormonal treatment; nor did NE-differentiation correlate to the decrease in serum PSA. CONCLUSIONS: Neuroendocrine differentiation in prostate cancer increases after 3 months of neoadjuvant hormonal treatment but does not correlate to the effects of hormonal treatment.

RESUMO

OBJECTIVES: To study neuroendocrine (NE) tumor cell differentiation in prostate cancer in relation to failure after radical prostatectomy. METHODS: Radical prostatectomy specimens from 103 of 111 patients randomized to 3-month neoadjuvant luteinizing hormone-releasing hormone-analogue treatment (neoadjuvant group) or to surgery alone (control group) were available for analysis. Immunohistochemistry using antibodies to chromogranin A (CGA) enabled detection of tumor cells with NE differentiation. NE differentiation was scored as NE-negative (0 to 1+) or NE-positive (2 to 3+). The number of CGA-positive cells/cm(2) tumor area on the slides was assessed in a separate analysis. The patients were followed up for 39 months after surgery, and a prostate-specific antigen value of 0.5 ng/mL or greater in two consecutive blood samples was considered biochemical failure. RESULTS: Kaplan-Meier analysis stratified for neoadjuvant hormonal treatment showed the failure rate to be significantly greater among those with NE-positive tumors than among those with NE-negative tumors. However, the number of CGA-positive cells/cm(2) was not a variable of prognostic significance. Instead, both NE differentiation and the CGA-positive cell count correlated with the tumor area on the slides (P = 0.0001). Multivariate analysis revealed the tumor area on the slide (P <0.0001) and positive surgical margins (P = 0.03) to be the only significant predictors of biochemical failure. CONCLUSIONS: The extension of NE differentiation in prostate cancer correlates with tumor volume and is not an independent prognostic factor of failure after radical prostatectomy.

RESUMO

OBJECTIVE: To determine the frequency of prostatic involvement in men with community-acquired febrile urinary tract infection. PATIENTS AND METHODS: This prospective study included 70 men (18-85 years old) who had a fever of >/=38.0 degrees C, symptoms or signs of urinary tract infection and a positive urine culture. Serum prostate-specific antigen (PSA) was measured and transrectal ultrasonography of the prostate and seminal vesicles performed during the acute phase of the disease and during a 1-year follow-up. RESULTS: Although only six patients had a tender prostate on digital rectal examination, the initial serum PSA level was elevated in 58 (83%) patients (median 14 ng/mL, range 0.54-140). There was no correlation between PSA levels, patient age, inflammatory response to infection or presence of positive blood cultures. Despite a rapid decline in PSA level after one month, there was a protracted decrease in some patients. After 3 months the median prostate volume was reduced by 31% (range 11-54; P<0.001) in 46 of 55 patients examined, and the width of the right and left seminal vesicle was reduced by 14% and 22%, respectively. The reductions in PSA and prostate volume were significantly correlated (r=0.36, 95% confidence interval 0.09-0.58; P=0.01). CONCLUSION: These results show that the prostate and seminal vesicles are frequently involved in men with febrile urinary tract infection and that PSA may be a useful marker of prostatic infection. The slow decline of PSA levels in some patients after appropriate antibiotic treatment indicates a protracted healing process and should be considered when PSA is used to detect prostate cancer.

RESUMO

OBJECTIVES: To evaluate tumor cell proliferation in relation to histopathologic regressive changes and failure after radical prostatectomy after a 3-month course of neoadjuvant luteinizing hormone-releasing hormone (LHRH) analogue treatment. METHODS: We evaluated slides from 103 radical prostatectomy specimens of the 111 patients participating in a randomized trial of a 3-month course of neoadjuvant LHRH analogue treatment before radical retropubic prostatectomy (n = 50) versus surgery alone (n = 53). The histopathologic regressive changes in the specimens were scored by two pathologists. Sections were stained with the anti-Ki-67 monoclonal antibody MIB-1. The proliferation index (PI) was defined as the proportion of Ki-67-positive cells in a random cell count. The patients were followed up until treatment failure or for a mean of 39 months among those without failure. RESULTS: In the neoadjuvant group, increasing histopathologic regressive changes correlated with a decrease in capsular penetration, positive surgical margins, and tumor cell proliferation but did not correlate with Gleason score in biopsies. Treatment failure was not related to the histopathologic regressive changes. In the neoadjuvant treatment group, progression-free survival was longer in the subgroup of patients with tumors with a PI less than 1.2% compared with those with tumors with a PI greater than 1.2% (P = 0.02). Multivariate analysis of PI and histopathologic and clinical features showed the PI (P = 0.002) and the pretreatment serum prostate-specific antigen level (P = 0.003) to be significant prognostic markers of failure in the neoadjuvant group. CONCLUSIONS: Tumor cell proliferation after 3 months of neoadjuvant hormonal treatment is a prognostic marker of failure after radical prostatectomy without correlation to Gleason score or the histopathologic regressive changes resulting from hormonal treatment.

RESUMO

OBJECTIVES: To determine whether the volume of prostatic adenomas as assessed by transrectal ultrasound (TRUS) influenced the outcome after transurethral resection of the prostate (TURP). METHODS: TRUS with total prostate and transition zone (TZ) volume determinations was performed preoperatively in 298 consecutive patients undergoing TURP for benign prostatic hyperplasia without prior urodynamic evaluation. Postoperatively, the outcome of surgery was stated as excellent (no or minor remaining symptoms), improved (but with some remaining symptoms), or failure (the same or aggravated symptoms) according to a patient-administered questionnaire. Six possible risk factors were evaluated: TZ volume 20 cc or less, neurologic disorders, previous TURP/transurethral incision of the prostate (TUIP), diabetes, indwelling catheter, and age older than 80 years. RESULTS: Thirty patients (10.1%) had treatment failure, 45 (15.1%) improvement, and 223 (74.8%) had excellent outcome. After subdivision into preoperative TZ volume of 20 cc or less and greater than 20 cc, it was found that the outcomes of 20.9% (n = 19) were failures if the TZ volume was 20 cc or less but only 5.3% (n = 11) if the TZ volume was greater than 20 cc. Additional independent risk factors for failure were neurologic disorders and previous TURP/TUIP. When all patients with risk factors were excluded (TZ volume 20 cc or less, neurologic disorders, previous transurethral surgery, and diabetes), the risk of failure was 3.3%. CONCLUSIONS: Patients with a preoperative TZ volume greater than 20 cc and no history of neurologic disorders, previous TURP/TUIP, or diabetes had a very high chance of favorable outcome after TURP, even though no pressure/flow evaluation had been performed preoperatively.

RESUMO

PURPOSE: Hormonal treatment administered before radical prostatectomy has been shown to decrease the rate of positive surgical margins. We determine whether preoperative hormonal treatment has any impact on the subsequent failure rate. MATERIALS AND METHODS: We prospectively evaluated 122 patients with stages T1bNxM0 to T3aNxM0, grades 1 to 3 prostate cancer, including 64 randomly assigned to immediate radical retropubic prostatectomy and 58 randomly assigned to radical retropubic prostatectomy preceded by 3 months of pretreatment with a gonadotropin-releasing hormone agonist. We performed intention to treat analysis on the data with failure defined as lymph node involvement, serum prostate specific antigen greater than 0.5 ng./ml., or the need for postoperative hormonal or radiation adjuvant treatment. RESULTS: The positive margin rate was 23.6 versus 45.5% in the pretreatment plus prostatectomy versus prostatectomy only groups (p = 0.016). There were 20 failures (34.5%) in the pretreatment plus prostatectomy subgroup and 26 (40.6%) in the prostatectomy only group (p = 0.48). A negative surgical margin was associated with a significantly lower risk of progression than a positive surgical margin (20.8 versus 50.0%, p = 0.0016), and progression was delayed by approximately 1 year after hormonal pretreatment. However, at a median followup of 38 months there was no difference in progression-free survival (p = 0.57). CONCLUSIONS: Although hormonal pretreatment significantly decreased the positive margin rate, it did not result in any difference in progression-free survival when followup exceeded 3 years. Thus, our current results do not support the routine administration of hormonal treatment before radical prostatectomy.
