RESUMEN

PURPOSE: Advancements in the diagnosis and treatment of prostate cancer (PC) have rapidly progressed through the past years. Various factors should be taken into account while treating individual patients to ensure optimal and careful decision making. The purpose of this consensus review is to summarize the current practice patterns when managing patients with advanced prostate cancer (APC) as there is still a lack of or very limited evidence on its clinical management in some areas. METHODS: Pre-defined questions were shared with experts prior to the consensus session that took place in Cairo, Egypt in April 2019 during the 8th International gastrointestinal, liver and uro-oncology conference (IGILUC). Voting was based mainly on the expert opinions of the panel after a thorough discussion and review of available evidence from guidelines or best evidence available concerning the topic at hand. RESULTS: A strong consensus or unanimity was reached on 47% of the proposed questions. Notably, the panelists reached consensus on several topics based on high-level expert opinion. These findings contribute in several ways to our understanding of the management of PC and provide a basis for future recommendations. There was also a lack of consensus on other several topics, which suggests the need for further supporting data addressing these knowledge gaps. CONCLUSION: This review offers a thorough understanding of APC practice and offers insight on the various opinions shared amongst experts in the field that can serve as guidance regionally and deepens our understanding of disease management globally.

RESUMEN

INTRODUCTION: Prostate cancer (PCa) is the most common solid neoplasm and the second leading cause of cancer death in men. After the Partin tables were developed, a number of predictive and prognostic tools became available for risk stratification. These tools have allowed the urologist to better characterize this disease and lead to more confident treatment decisions for patients. The purpose of this study is to critically review the decision-making tools currently available to the urologist, from the moment when PCa is first diagnosed until patients experience metastatic progression and death. EVIDENCE ACQUISITION: A systematic and critical analysis through Medline, EMBASE, Scopus and Web of Science databases was carried out in February 2016 as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The search was conducted using the following key words: "prostate cancer," "prediction tools," "nomograms." EVIDENCE SYNTHESIS: Seventy-two studies were identified in the literature search. We summarized the results into six sections: Tools for prediction of life expectancy (before treatment), Tools for prediction of pathological stage (before treatment), Tools for prediction of survival and cancer-specific mortality (before/after treatment), Tools for prediction of biochemical recurrence (before/after treatment), Tools for prediction of metastatic progression (after treatment) and in the last section biomarkers and genomics. CONCLUSIONS: The management of PCa patients requires a tailored approach to deliver a truly personalized treatment. The currently available tools are of great help in helping the urologist in the decision-making process. These tests perform very well in high-grade and low-grade disease, while for intermediate-grade disease further research is needed. Newly discovered markers, genomic tests, and advances in imaging acquisition through mpMRI will help in instilling confidence that the appropriate treatments are being offered to patients with prostate cancer.

RESUMEN

OBJECTIVE: To assess changes in conditional disease-free survival (DFS) rates after radical prostatectomy (RP) and how the impact of well-known prognostic factors evolves over time. MATERIALS AND METHODS: There were 2813 patients treated with RP and postoperatively followed with clinical and prostate-specific antigen assessments. Estimation of conditional survival (CS) probabilities used the Kaplan-Meier method. Multivariable Cox regression model was used to calculate proportional hazard ratios for prediction of DFS after stratification by prognostics characteristics. RESULTS: The 5-year DFS rate was 71.2%. The DFS rate 5 years after RP increased to 77.4% (+8.7%), 82.1% (+15.3%), 88.0% (+23.6%), and 94.0% (+32.0%) for patients surviving without recurrence 1, 2, 3, and 4 years after RP, respectively. This represented a relatively stable survival gain per survived year ranging from 5.6% to 8.7%. The conditional 5-year DFS improves mainly for disease-free surviving patients with adverse pathologic factors. Among patients with pT3b-4 disease, the probability of surviving without recurrence to year 5 increased from 20.7% at the time of presentation to 78.9% for patients surviving 4 years without recurrence (+281%) as compared to +12.5% in pT2 disease. The impact of Gleason score and pT stage on CS estimates remained stable over time. Findings were confirmed upon multivariable analyses. CONCLUSION: The period elapsed from RP is associated with DFS. The risk of recurrence decreases with increasing survivorship, mainly in patients with adverse pathologic factors. CS can provide relevant information for clinicians and patients giving an update of their risk of subsequent recurrence.

RESUMEN

PURPOSE: To evaluate the safety and efficacy of retroperitoneal laparoscopic resection in patients with pheochromocytoma in a retrospective study. METHODS: Clinical data of patients with adrenal and extra-adrenal pheochromocytomas, operated on between September 1998 and September 2008 at two institutions, including information on patient demographics, surgical procedure, complications and hospital stay were retrieved. RESULTS: Seventy-two retroperitoneal laparoscopic resections were performed (68 patients, 30 males/38 females). Mean age was 51.4 years (15-87 years). Four patients had a bilateral pheochromocytoma. Median BMI was 27 kg/m(2) (interquartile range 23-29). Mean tumour diameter was 4.6 cm (1.3-9). Thirteen patients had a tumour >6 cm. Mean operation time was 110 min (40-210), and median blood loss during surgery was 160 ml (0-1200 ml). Duration of surgery significantly increased with BMI (p = 0.004) and tumour size (p = 0.004). Four patients required conversion to open surgery (two bleeding, one severe adhesion to inferior vena cava and one renal artery aneurysm). Five patients required a blood transfusion with minor postoperative complications in three patients. Major perioperative haemodynamic variations (systolic blood pressure > 180 mmHg, diastolic blood pressure < 70 mmHg) were observed in 54 % of patients, 30 % required postoperative adrenergic drug treatment. The only predictive factor of a perioperative haemodynamic complication was the high level of normetanephrine in the preoperative blood samples. The median postoperative hospital stay was 4.5 days. Blood loss, postoperative complication and postoperative hospital stay did not increase in patients with tumours >6 cm. CONCLUSION: Retroperitoneal laparoscopic surgery for pheochromocytoma is reproducible, safe and effective.

RESUMEN

PURPOSE: Biopsy and final pathological Gleason score (GS) are inconstantly correlated with each other. The aim of the current study was to develop and validate a predictive score to screen patients diagnosed with a biopsy GS ≤ 6 prostate cancer (PCa) at risk of GS upgrading. METHODS: Clinical and pathological data of 1,179 patients managed with radical prostatectomy for a biopsy GS ≤ 6, clinical stage ≤ T2b and preoperative PSA ≤ 20 ng/ml PCa were collected. The population study was randomly split into a development (n = 822) and a validation (n = 357) cohort. A prognostic score was established using the independent factors related to GS upgrading identified in multivariate analysis. The cutoff value derived from the area under the receiver operating characteristic curve of the score. RESULTS: After RP, the rate of GS upgrading was 56.7%. In multivariate analysis, length of cancer per core > 5 mm (OR 2.938; p < 0.001), PSA level > 15 ng/ml (OR 2.365; p = 0.01), age > 70 (OR 1.746; p = 0.016), number of biopsy cores > 12 (OR 0.696; p = 0.041) and prostate weight > 50 g (OR 0.656; CI; p < 0.007) were independent predictive factors of GS upgrading. A score ranged between -4 and 12 with a cutoff value of 2 was established. In the development cohort, the accuracy of predictive score was 63.7% and the positive predictive value was 71.2%. Results were confirmed in the validation cohort. CONCLUSION: This predictive tool might be used to screen patients initially diagnosed with low-grade PCa but harboring occult high-grade disease.

RESUMEN

AIMS: To evaluate stress urinary incontinence (SUI), overactive bladder (OAB), and obstructive symptoms in patients with post-radical prostatectomy urinary incontinence (pRP-UI) treated with the bulbar compressive sling TOMS, and investigate the effect of each urinary symptom on urinary bother. MATERIALS AND METHODS: We prospectively followed 40 patients with pRP-UI before, and 6 and 12 months (T6 and T12, respectively) after implantation of the TOMS sling. Urinary symptoms were evaluated using the following questionnaires: USP, ICIQ, UCLA-PCI (urinary bother domain), PGI-I, and daily pad use. Success was defined as patients wearing no pads or using one security pad. RESULTS: Significant improvement of mean USP-SUI (6.97/9, 3.35, 3.02, P < 0.001) and USP-OAB domains (8.1/21, 5.74, 5.71, P < 0.001), ICIQ (15.15/21, 8.17/21, 8.35/21, P < 0.01), urinary bother (92.5/100, 42.5, 41.87, P < 0.001), and pad number (2.78, 1.01, 1.03, P < 0.001) were noted between baseline, T6, and T12. At baseline, 32 (80%) patients reported urge incontinence. Urinary bother strongly correlated with UPS-SUI but not with UPS-OAB score. At T12, 22 (55%) patients with pad use were considered cured, and 13 (32.5%) patients reported a greatly improved urinary tract condition (PGI-I). Improvement of USP-SUI and USP-OAB scores correlated with improvement of ICIQ and PGI scores. The USP-obstructive domain remained unchanged. CONCLUSION: The TOMS sling improves SUI and OAB symptoms without generating obstructive symptoms. OAB symptoms including urge incontinence reported by most patients were not a major concern at baseline; however, improvement of these symptoms was associated with improvement of continence and PGI-I scores.

RESUMEN

PURPOSE: To study the prognostic value of extent, number, and location of positive surgical margins (PSM). METHODS: A total of 1,504 consecutive adjuvant treatment naive and node-negative radical prostatectomy men were included in a prospective database including extent, number, and location of PSM. Mean follow-up was 33 months. Endpoint was biochemical progression-free (bPFS) survival. The impact of margin status and characteristics was assessed in time-dependent analyses using Cox regression and Kaplan-Meier methods. RESULTS: PSM was reported in 26.7 % of patients. The predominant PSM locations were apex and posterior locations. Median PSM length was 4.0 mm. The 2-year bPFS was 73.7 % in PSM patients as compared to 93.0 % in NSM patients (p < 0.001). The rate and extent of PSM increased significantly with pathologic stage (p < 0.001). The extent of PSM length was linearly correlated with bPFS (p = 0.017, coefficient: -0.122). In univariable analysis, extent and number of PSM were significantly linked to outcomes. None of PSM subclassifications significantly influenced the bPFS rates in the subgroup of pT2 disease patients. Conversely, stratification by PSM location (apex vs. other locations, p = 0.008), by PSM number (p = 0.006), and by PSM length (p < 0.001) showed significant differences in pT3-4 cancer patients. In that subgroup, PSM length also added to bPFS prediction using PSM status only in multivariable models (p = 0.005). CONCLUSIONS: PSM subclassifications do not improve the biochemical recurrence prediction in organ-confined disease. In non-organ-confined disease, PSM length (≥3 mm), multifocality (≥3 sites), and apical location are significantly linked to poorer outcomes and could justify a more aggressive adjuvant treatment approach.

RESUMEN

BACKGROUND: In spite of the increasing use of robot-assisted radical prostatectomy (RALP) worldwide, no level 1 evidence-based benefit favouring RALP versus pure laparoscopic approaches has been demonstrated in extraperitoneal laparoscopic procedures. OBJECTIVE: To compare the operative, functional, and oncologic outcomes between pure laparoscopic radical prostatectomy (LRP) and RALP. DESIGN, SETTING, AND PARTICIPANTS: From 2001 to 2011, 2386 extraperitoneal LRPs were performed consecutively in cases of localised prostate cancers. INTERVENTION: A total of 1377 LRPs and 1009 RALPs were performed using an extraperitoneal approach. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Patient demographics, surgical parameters, pathologic features, and functional outcomes were collected into a prospective database and compared between LRP and RALP. Biochemical recurrence-free survival was tested using the Kaplan-Meier method. Mean follow-up was 39 and 15.4 mo in the LRP and RALP groups, respectively. RESULTS AND LIMITATIONS: Shorter durations of operative time and of hospital stay were reported in the RALP group compared with the LRP group (p<0.001) even beyond the 100 first cases. Mean blood loss was significantly lower in the RALP group (p<0.001). The overall rate and the severity of the complications did not differ between the two groups. In pT2 disease, lower rates of positive margins were reported in the RALP group (p=0.030; odds ratio [OR]: 0.396) in multivariable analyses. The surgical approach did not affect the continence recovery. Robot assistance was independently predictive for potency recovery (p=0.045; OR: 5.9). Survival analyses showed an equal oncologic control between the two groups. Limitations were the lack of randomisation and the short-term follow-up. CONCLUSIONS: Robotic assistance using an extraperitoneal approach offers better results than pure laparoscopy in terms of operative time, blood loss, and hospital stay. The robotic approach independently improves the potency recovery but not the continence recovery. When strict indications of nerve-sparing techniques are respected, RALP gives better results than LRP in terms of surgical margins in pathologically organ-confined disease. Longer follow-up is justified to reach conclusions on oncologic outcomes.

RESUMEN

OBJECTIVE: Positive surgical margins (PSMs) in men undergoing radical prostatectomy (RP) for prostate cancer are associated with an increased risk of biochemical recurrence. This study evaluated the long-term (>10 year) impact of PSMs on biochemical recurrence after RP in adjuvant treatment-naïve pT2-pT4 N0 men and determined predictors of prostate-specific antigen (PSA) failure. MATERIAL AND METHODS: The institutional registry of 1276 patients who underwent RP at Henri Mondor Hospital from 1988 to 2001 was reviewed, identifying 403 patients with regular follow-up at the time of analysis. The study included 108 patients with PSMs who did not receive neoadjuvant or adjuvant therapy before PSA relapse. Median follow-up was 12.2 years. PSA failure was defined by a PSA rising by more than 0.2 ng/ml and biochemical recurrence-free survival (RFS) was estimated using the Kaplan-Meier method. Cox proportional hazard regression models were used to analyse clinicopathological variables associated with biochemical recurrence. RESULTS: Biochemical recurrence 10 years after RP was 33.5% for patients regardless of the margin status. The 10-year biochemical RFS was 73% in men with negative margins compared to 49% in the case of PSM (p < 0.001). In multivariate analysis, margin status was a significantly predictive for PSA failure (hazard ratio 1.46, p = 0.04). After stratification by pathological stage, margin status was significantly predictive for biochemical RFS in pT2 (p < 0.001) and pT3a (p < 0.001), whereas the impact of PSM did not reach significance in pT3b (p = 0.16). CONCLUSIONS: After 10-year follow-up, PSMs remain an independent risk factor of biochemical RFS after RP with less relevant impact in pT3b disease. Randomized prospective trials are needed to determine the place of adjuvant versus delayed radiotherapy.

RESUMEN

OBJECTIVES: To assess correlations between concomitant high-grade prostatic intraepithelial neoplasia (HGPIN), pathological features and oncologic outcomes after radical prostatectomy (RP). MATERIAL AND METHODS: We prospectively collected a single-institution database of 2,351 patients who underwent RP between 1998 and 2011. RESULTS: 1,272 (54.1%) patients had HGPIN on specimens. The mean follow-up was 28 months. Presence of HGPIN was significantly associated with a favorable preoperative risk status and with pathological factors of poor prognosis in RP specimens. Patients without HGPIN had a worse biochemical recurrence-free survival compared with those with HGPIN in RP specimen (log-rank test: p = 0.015). The 3-year RFS rate was 73.9% for the HGPIN group versus 67.2%. The absence of HGPIN was also significantly correlated with the use of androgen deprivation treatment during the follow-up (p < 0.001). In Cox multivariate analysis, taking into account the other prognostic pathological factors, HGPIN was not an independent predictive factor for PSA failure (p = 0.868). CONCLUSION: HGPIN is associated with factors of good prognosis but fails to show independent significance when classical pathological prognostic factors are taken into account.

RESUMEN

OBJECTIVES: To evaluate the incidence, and clinical and bacterial features of iatrogenic prostatitis within 1 month after transrectal ultrasound-guided biopsy for detection of prostate cancer. METHODS: From January 2006 to December 2009, 3000 patients underwent a 21-core transrectal ultrasound-guided prostate biopsy at Henri Mondor Hospital (Créteil, France) and were prospectively followed. All patients had a fluoroquinolone antimicrobial prophylaxis for 7 days. The primary study end-point was to evaluate the incidence of iatrogenic acute prostatitis within 1 month after the biopsy. The secondary end-point was to analyze the clinical and the bacterial features of the prostatitis. RESULTS: Overall, 20 patients of the entire study population (0.67%) had an acute bacterial prostatitis within 2.90 ± 1.77 days (range 1-7 days) after the transrectal ultrasound-guided biopsy. The groups of patients with (n = 20) and without (n = 2980) infection were similar in terms of age, prostate-specific antigen level and prostate volume. Escherichia coli was the only isolated bacteria. The subsequent tests for antibiotic susceptibility showed a 95% resistance for fluroquinolone and amoxicillin. Resistance to amoxiclav, trimethoprim-sulfamethoxazole, third generation cephalosporin and amikacin was 70%, 70%, 25% and 5% respectively. No resistance to imipenem was reported. They were all admitted for treatment without the need of intensive care unit referral. Complete recovery was achieved after 21.4 ± 7 days of antibiotic treatment. CONCLUSIONS: A fluroquinolone-based regimen still represents an appropriate prophylaxis protocol to minimize the risk of acute prostatitis secondary to prostate biopsy. Patients should be provided the appropriate care soon after the onset of the symptoms. An intravenous third generation cephalosporin or imipenem-based therapy seem to provide satisfying results.

RESUMEN

BACKGROUND: The debate on the optimal number of prostate biopsy core samples that should be taken as an initial strategy is open. OBJECTIVE: To prospectively evaluate the diagnostic yield of a 21-core biopsy protocol as an initial strategy for prostate cancer (PCa) detection. DESIGN, SETTING, AND PARTICIPANTS: During 10 yr, 2753 consecutive patients underwent a 21-core biopsy scheme for their first set of biopsy specimens. INTERVENTION: All patients underwent a standardized 21-core protocol with cores mapped for location. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The PCa detection rate of each biopsy scheme (6, 12, or 21 cores) was compared using a McNemar test. Predictive factors of the diagnostic yield achieved by a 21-core scheme were studied using logistic regression analyses. RESULTS AND LIMITATIONS: PCa detection rates using 6 sextant biopsies, 12 cores, and 21 cores were 32.5%, 40.4%, and 43.3%, respectively. The 12-core procedure improved the cancer detection rate by 19.4% (p=0.004), and the 21-biopsy scheme improved the rate by 6.7% overall (p<0.001). The six far lateral cores were the most efficient in terms of detection rate. The diagnostic yield of the 21-core protocol was >10% in prostates with volume >70 ml, in men with a prostate-specific antigen level<4 ng/ml, with a prostate-specific antigen density (PSAD) <0.20 ng/ml per gram. A PSAD <0.20 ng/ml per gram was the strongest independent predictive factor of the diagnostic yield offered by the 21-core scheme (p<0.001). The 21-core protocol significantly increased the rate of PCa eligible for active surveillance (62.5% vs 48.4%; p=0.036) than those detected by a 12-core scheme without statistically increasing the rate of insignificant PCa (p=0.503). CONCLUSIONS: A 21-core biopsy scheme improves significantly the PCa detection rate compared with a 12-core protocol. We identified a cut-off PSAD (0.20 ng/ml per gram) below which an extended 21-core scheme might be systematically proposed to significantly improve the overall detection rate without increasing the rate of detected insignificant PCa.

RESUMEN

OBJECTIVES: To establish the rate of higher risk criteria in various definitions of an active surveillance population. PATIENTS AND METHODS: Over a period of 10 years, 1161 patients were diagnosed with prostate cancer and underwent radical prostatectomy at our institution. Statistical analysis was performed comparing the rates of upgrading, extracapsular extension, seminal vesical involvment and unfavourable disease (Gleason score upgrading >6 and/or T3 disease) for six groups of patients eligible for the University of Toronto, Royal Marsden, John Hopkins, University of California San Francisco, Memorial Sloan Kettering Cancer Center and Prospective Randomized International Active Surveillance. RESULTS: Active surveillance protocols including patients with biopsy Gleason score 3+4 (Royal Marsden) had significantly higher rates of extracapsular extension (P = 0.009), upgrading to pathological Gleason >3+4 (P = 0.004) and unfavourable disease (P = 0.001) compared to the most stringent John Hopkins criteria. Unfavourable disease was found in more than 40% of patients in all series with no significant difference between the Gleason 6 protocols. Biochemical recurrence-free survival at 5 and 10 years was 76.7% and 63.3% for the entire cohort. Positive margins (P < 0.001), pT3 tumours (P = 0.006) and unfavourable disease (P < 0.001) were significant predictors of biochemical recurrence. CONCLUSIONS: Active surveillance in patients with Gleason 3+4 presents a risk of missing unfavourable disease and should be limited to older patients with comorbidities. The differences in inclusion criteria between Gleason 6 protocols did not have a significant impact on the pathological results.

UNLABELLED: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Even after a negative set of prostate biopsies, the risk of undetected prostate cancer remains clinically significant. Predictive markers of such a risk are undefined. In addition to PSA and PSAD, low prostate volume and %fPSA are interesting time-varying risk factors and are relevant in biopsy decision-making. OBJECTIVE: To assess prospectively the time-varying risk of rebiopsy and of prostate cancer (PCa) detection after an initial negative biopsy protocol. PATIENTS AND METHODS: Over a period of 10 years, 1995 consecutive patients with initially negative biopsies were followed. Rebiopsies were performed in patients who had a persistent suspicion of PCa. Predictive factors for rebiopsy and for PCa detection were tested using univariate, multivariate and time-dependent models. RESULTS: A total of 617 men (31%) underwent at least one rebiopsy after a mean follow-up of 19 months. PCa detection rates during second, third, and fourth sets of biopsies were 16.7, 16.9 and 12.5%, respectively. The overall rate of detected PCa was 7.0%. The 5-year rebiopsy-free and PCa-free survival rates were 65.9 and 92.5%, respectively. Indications for rebiopsy were more frequently reported in patients having a high prostate-specific antigen (PSA) level (P = 0.006) or a high PSA density (PSAD; P < 0.001) and in younger patients (P = 0.008). The risk of PCa on rebiopsies was not correlated with age, but significantly increased more than twofold in cases of PSA >6 ng/mL, PSAD >0.15 ng/mL/g, free-to-total PSA ratio (%fPSA) <15, and/or prostate volume <50 mL. Time-dependent analyses were in line with these findings. The main study limitation was the lack of control of the absence of PCa and PSA kinetics in men not rebiopsied. CONCLUSIONS: The overall risk of detected PCa after an initial negative biopsy was low. In addition to PSA and PSAD, which are well-used in rebiopsy indications, low prostate volume and %fPSA are interesting time-varying risk factors for PCa on rebiopsy and could be relevant in biopsy decision-making.

RESUMEN

INTRODUCTION: The effects of intracavernous alprostadil injection (IAI), a primary treatment for post-radical prostatectomy (RP) erectile dysfunction (ED) (pRPED), on the sex life of women partnered with men who have undergone RP have received little attention. AIMS: The aim of this study is to investigate the sexual quality of life in female partners of men receiving IAIs for pRPED. METHODS: We retrospectively studied the sex lives of 152 women partnered with men who were being treated for pRPED with IAI and previously had normal erectile function. Women completed the Index of Sexual Life (ISL) questionnaire 1 year after their partner's RP. Male patients completed the International Index of Erectile Function (IIEF-15), the Erection Hardness Score (EHS) questionnaire, the International Consultation on Incontinence Questionnaire (ICIQ), and the UCLA Prostate Cancer Index (UCLA-PCI) urinary function questionnaire. Penile pain was assessed using the visual analog scale (VAS). Statistical analysis was performed using t-tests, Spearman correlation, and multiple linear regression. MAIN OUTCOME MEASURES: Female sexual life satisfaction (SLS), sexual drive (SD), and general life satisfaction (GLS) were assessed using the ISL questionnaire. RESULTS: Mean ages for the 104 couples included were 62.3 and 59.8 years for the men and women, respectively. Mean ISL, SD, SLS, and GLS scores at 12 months were 25.4, 3.8, 14.1, and 7.5, respectively. ISL scores were strongly correlated with IIEF-15 domains, mainly erectile function (r > 0.41, P < 0.00002) and intercourse satisfaction (r > 0.27, P < 0.005). Age and VAS, ICIQ, and UCLA-PCI scores were negatively correlated with some ISL domains. IIEF-15 erectile function and intercourse satisfaction were the most significant domains predicting female SLS. An IIEF-15 erectile function of 25 corresponded to a 75% chance of an SLS score ≥18. CONCLUSION: Indexes of female sexual quality of life were low overall but were highly correlated with the partner's response level to IAI treatment. IAI-related pain, increased age, and poor urinary function of the male partner appear to negatively impact female sex life.

RESUMEN

PURPOSE: At the time of castration resistance, it is recommended to realize hormonal manipulations before chemotherapy. We evaluated the impact of a switch from GnRH agonist to antagonist in patients with castration-resistant prostate cancer on PSA and testosterone levels at 3 months. METHODS: Retrospectively, 17 patients from 5 different centers undergoing androgen deprivation therapy and presenting rising PSA confirmed on 3 blood samples 2 weeks apart and despite a castrate testosterone level (<0.5 ng/ml) were reviewed. Antiandrogen withdrawal syndrome had been tested before the switch. Degarelix was administered as followed: 240 mg for the first injection and then 80 mg every month, subcutaneously. We evaluated the PSA and testosterone level variation 3 months after the switch. Patients who experienced a variation in PSA of less than 10% compared to the baseline or who had a more than 10% PSA decrease were defined as responders. RESULTS: Mean PSA level at the switch was 34.3 ± 50.3 ng/ml, with a mean testosterone level of 0.21 ± 0.13 ng/ml. Three months after the switch, mean PSA level was 59.9 ± 81.6 ng/ml (P = 0.061), with a mean testosterone level of 0.19 ± 0.08 ng/ml (P = 0.086). At 3 months, 4 patients (23%) responded to therapy. Thirteen patients (77%) experienced a rise in PSA of more than 10% compared to baseline; 41% of patients decreased their testosterone level. The limitations of this study are its retrospective nature and the limited number of patients. CONCLUSION: Switch from an agonist to an antagonist of GnRH has a limited impact on PSA at 3 months in castration-resistant prostate cancer patients.

RESUMEN

OBJECTIVES: Outcomes of continence, erectile function, and oncologic control are well-described in isolation especially for the retropubic open approach. However, only few series have yet reported combined results after radical prostatectomy. To determine the proportion of men who are continent, potent, and cancer-free (trifecta rate) 2 years after robot-assisted laparoscopic radical prostatectomy (RALRP). MATERIALS AND METHODS: We included patients who underwent a RALRP at our department and who were followed during at least 2 years. Men who were impotent or incontinent before the surgery were excluded from the analysis. Overall, 500 men were included. All patients prospectively completed validated questionnaires (IIEF-5, ICS) before the medical visit and concerning their voiding and sexual disorders, preoperatively, 3, 6, 12, 18, and 24 months after RALRP. Biochemical recurrence was defined as any detectable serum PSA (≥ 0.2 ng/ml). The study end point was the trifecta rate (cancer control, continence, and potency) at 2 years of the surgery. Predictive factors of the trifecta outcome were assessed in univariate and multivariate analyses. RESULTS: Median age and PSA level were 62.2 years and 9.7 ng/mL. A trifecta outcome was achieved in 44% and 53% of men at 12 and 24 months, respectively. The 2-year trifecta rate reached 62% in men undergoing bilateral nerve-sparing surgery and 71% in men < 60 years. Age < 60 years, PSA level < 10 ng/ml, organ-confined disease, and bilateral nerve-sparing procedure were significantly associated with the 2-year trifecta outcome. CONCLUSION: Two years after RALRP, the trifecta outcome is achieved in 53% of preoperatively potent and continent men.

RESUMEN

PURPOSE: To assess the pathological and the oncologic outcomes of the prostate cancer (PCa) missed by 6- and 12-core biopsy protocols by using a reference 21-core scheme. MATERIALS AND METHODS: Between 2001 and 2009, all patients who had PCa detected in an initial 21-core TRUS biopsy scheme and were treated by a radical prostatectomy (RP) were included. Patients were sorted in 3 groups according to the diagnosis site: sextant (6 first cores; group 1), peripheral zone (12 first cores; group 2) or midline/transitional zone (after 21 cores; group 3). Demographics, pathological features in biopsy and RP specimens and follow-up after RP were analyzed. The 5-year progression-free survival (PFS) was studied in the 3 groups. RESULTS: During the study period, 443 patients were included. Among them, 67, 23.7 and 9.2% were, respectively, diagnosed in groups 1, 2 and 3. Among PCa diagnosed in midline/transition zone cores, 42% were intermediate or high risk. Unfavorable disease was more frequently reported in group 1 in terms of extraprostatic extension (P = 0.001), high Gleason score (P = 0.001) and progression (P = 0.001). No significant difference was observed between groups 2 and 3 in terms of pathological features in RP specimens and oncologic outcome. The 5-year PFS was 89.7% and not significantly different in patients diagnosed with a 12-core scheme compared to those diagnosed only with 21-core scheme (P = 0.332). CONCLUSIONS: Our findings emphasize that PCa diagnosed only in a 21-core protocol is at least as aggressive as PCa detected in a 12-core scheme. This study invalidates the widespread idea sustaining that cancers diagnosed by more than 12 biopsies are less aggressive.

RESUMEN

OBJECTIVE: To identify the risk of failure of active surveillance (AS) in men who had the Prostate Cancer Research International: Active Surveillance (PRIAS) criteria and had undergone radical prostatectomy (RP), by studying as primary endpoints the risk of unfavourable disease in RP specimens (stage >T2 and/or Gleason score >6) and of biochemical progression after RP. PATIENTS AND METHODS: We assessed 626 patients who had the PRIAS criteria for AS defined as T1c/T2, PSA level of ≤10 ng/mL, PSA density (PSAD) of <0.2 ng/mL per mL, Gleason score of <7, and one or two positive biopsies. All patients underwent immediate RP at our department between January 1991 and December 2010. Multivariate logistic regression was used to test factors correlated with the risk of unfavourable prostate cancer. The risk of progression was tested using multivariate Cox regression models. Biochemical recurrence-free survival (BFS) was established using the Kaplan-Meier method. RESULTS: Pathological study of RP specimens showed upstaging (>T2) in 129 patients (20.6%), upgrading (Gleason score >6) in 281 (44.9%) and unfavourable disease in 312 patients (50%). There was a statistically non-significant trend for BFS at P = 0.06. Predictors of favourable tumours were age <65 years (P = 0.005), one vs two positive biopsies (P = 0.01) and a biopsy core number >12 (P = 0.005). Preoperative factors predicting disease progression were a PSAD of >0.15 ng/mL(2) (P = 0.008) and biopsy core number of ≤12 (P = 0.017). CONCLUSIONS: Even with stringent AS criteria, the rate of unfavourable disease remains high. Predictive factors of unfavourable disease and biochemical progression should be considered when including patients in AS protocols.

RESUMEN

OBJECTIVES: To report our surgical technique and outcomes after extraperitoneal robot-assisted laparoscopic radical prostatectomy (RALRP). MATERIALS AND METHODS: At Henri Mondor's Hospital, we performed the first RALRP in 2001 and started to perform routinely RALRP since 2006. Preoperative characteristics, perioperative parameters, functional and oncological outcomes were collected in a prospective database and studied. All parameters were tested in patients undergoing RALRP beyond the learning curve of each surgeon. The overall cohort included 792 patients. RESULTS: RALRP offers interesting results in terms of hospital stay, operative time, and blood loss. The overall rate of complications was low, especially concerning the rates of anastomosis' complications. An extraprostatic extension was seen in 42.8 % of specimens. The overall rate of positive margins was 30.7 % of specimens. In our cohort, after a mean follow-up of 19 months, 8.7 % of PSA failure has been reported. The rate of continence was 77.4 % at 6 months and 96.8 % at 2 years. The rate of potency was 17 % at 3 months and 60.9 % at 2 years. The 2-year rate was 86.7 % in case of intrafascial dissection. A trifecta outcome was achieved in 44 and 53 % of men at 12 and 24 months, respectively. CONCLUSIONS: The extraperitoneal approach confers interesting results in terms of perioperative parameters as previously described in series using a transperitoneal approach. Functional outcomes in terms of continence and potency recovery after extraperitoneal seem equivalent to those reported after transperitoneal RALRP. Longer follow-up is warranted to confirm our favorable mid-term oncologic outcomes.
