RESUMO

OBJECTIVES: Knowing the treatment's time of a complex stone is important for operating programming. It depends on the installation time, renal access time and the rate of fragmentation. The main objective of the study is to calculate the processing speed of complex stones by the percutaneous mini-nephrolithotomy (mini-NLPC) technique. POPULATION AND METHODS: A prospective single-center study was carried out between November 2019 and October 2020. Patients treated with mini-NLPC and with a result without fragment were included. The stone volume was measured using 3D reconstruction software and the operating time was differentiated into installation time, renal access time and fragmentation time. RESULTS: Of the 36 patients treated by the percutaneous technique, 20 patients were included. The median 3D volume of the stones was 4145 mm3 (2211-6998). The median duration of the intervention time was 104.5min (80-125). The fragmentation speed was 48.2 mm3min-1 (30.2-62.5) taking into account the total duration of the intervention and 110.4 mm3min-1 (85.3-126.5) in taking into account only the duration of fragmentation. CONCLUSION: The fragmentation speed for complex stones was 48.2 mm3min-1 (30.2-62.5) taking into account all the different operating times. It would be interesting to compare these results with that of ureteroscopy with the same methodology. LEVEL OF PROOF: C.

RESUMO

PURPOSE: To compare different extractions routes for robot-assisted living donor nephrectomy in terms of post-operative pain and renal function recovery. METHODS: Live donor kidney transplantation data from our institution were reviewed from November 2011 to March 2017. Postoperative pain was estimated using cumulative painkillers consumption. Variables were compared between the 3 groups with ANOVA for continuous data, χ2 test for categorial data. A survival analysis with Kaplan-Meier curve assessing time to transplant recipient nadir was performed to compare the renal function recovery. RESULTS: Sixty-three RLDN were performed (23 iliac, 23 vaginal and 17 umbilical extractions). There was no significant difference between the three groups in terms of operative time, blood lost, warm ischemia time, cumulative painkiller consumption and renal function recovery time. Postoperative complications for Umbilical, Vaginal and Iliac were, respectively, of 0, 3 and 1. No major difference was found between the 3 groups beside a slightly longer hospital stay in the iliac group. CONCLUSION: Iliac incision might impact post-operative pain with a moderate but significant longer hospital stay. Vaginal extraction is an option when cosmetic outcomes present a real demand. The three options appeared to be safe and should be discussed with the patient in regard of the surgeon experience.

RESUMO

PURPOSE: Robotics in surgery is a recent innovation. This technology offers a number of attractive features in laparoscopy. It overcomes the difficulties with fixed port sites by restoring all 6 degrees of freedom at the instrument tips, provides new possibilities for miniaturization of surgical tasks and allows remote controlled surgery. We investigated the applicability of remote controlled robotic surgery to laparoscopic radical prostatectomy. MATERIALS AND METHODS: Our previous experience with laparoscopic prostatectomy served as a basis for adapting robotic surgery to this procedure. A surgeon at a different location who activated the tele-manipulators of the da Vinci∗ robotic system performed all steps of the intervention. A scrub nurse and second surgeon who stood at patient side had limited roles to port and instrument placement, exposure of the operative field, assistance in hemostasis and removal of the operative specimen. Our patient was a 63-year-old man presenting with a T1c tumor discovered on 1 positive sextant biopsy with a 3+3 Gleason score and 7 ng./ml. preoperative serum prostate specific antigen. RESULTS: The robot provided an ergonomic surgical environment and remarkable dexterity enhancement. Operating time was 420 minutes, and the hospital stay lasted 4 days. The bladder catheter was removed 3 days postoperatively, and 1 week later the patient was fully continent. Pathological examination showed a pT3a tumor with negative margins. CONCLUSIONS: Robotically assisted laparoscopic radical prostatectomy is feasible. This new technology enhances surgical dexterity. Further developments in this field may have new applications in laparoscopic tele-surgery.

RESUMO

Percutaneous nephrolithotomy (PCNL) is considered to be the first line of treatment for large renal stones. Though PCNL comes with higher morbidity, its efficacy is unbeaten by other minimally invasive modalities. However, potential complications, such as bleeding, occur. Improved skills and modifications of the procedure may reduce the probability of adverse outcomes. This article discusses the current trends and standards in PCNL technique with special focus on all important steps as positioning, access, instruments, dilation, disintegration, and exit, including outcomes, complication management, and training modalities.

RESUMO

OBJECTIVE: To evaluate the impact of radical prostatectomy on lower urinary tract symptoms by using the International Prostate Symptom Score and International Prostate Symptom Score quality of life. METHODS: The present prospective study comprised 804 patients having localized prostate cancer who underwent radical prostatectomy. International Prostate Symptom Score and International Prostate Symptom Score quality of life were recorded preoperatively, and at 1, 3, 6, 12 and 24 months. Two study groups were considered: group 1 included patients with International Prostate Symptom Score ≤7 (mild) and group 2 included patients with International Prostate Symptom Score ≥8 (moderate to severe). Student's t-test and logistic regression were carried out to detect a predictive factor of International Prostate Symptom Score ≤7 at 24 months. RESULTS: The mean International Prostate Symptom Score was 5.58 ± 6.6, 11.12 ± 7.1 and 7.62 ± 6 at baseline, 1 month and 3 months, respectively (P <0.0001). The mean quality of life score showed the same evolution with a significant difference at 1 and 3 months. The mean International Prostate Symptom Score was initially 1.57 ± 1.9 in group 1 and 13.51 ± 5.5 in group 2 (P <0.0001), evolving to 3.41 ± 3.1 and 7.69 ± 5.8 at 24 months (P <0.0001), respectively. The mean quality of life score was significantly different between the groups initially, and at 6 and 12 months with P <0.0001, P = 0.005 and P = 0.02, respectively. The multivariate logistic regression showed that age, prostate volume and preoperative International Prostate Symptom Score were independent predictive factors of International Prostate Symptom Score ≤7 at 24 months (P <0.0001). In group 2, 47 patients (17%) had an International Prostate Symptom Score ≥8 at 24 months, 15 of them (32%) having a QoL score ≥3. CONCLUSIONS: The present study shows the beneficial impact of radical prostatectomy on lower urinary tract symptoms. However, a proportion of patients with a baseline International Prostate Symptom Score ≥8 maintain the same score at 24 months, with worsening in quality of life score in one-third of them.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: Prognostic factors in pathologic node-positive patients after radical cystectomy are debated. Extranodal extension (ENE) and lymph node density (LND) are strong predictors of survival. The aim of this study was to assess factors predictive of survival and to evaluate the prognostic significance of the tumor, node, metastasis staging system (TNM) nodal classification in a retrospective cohort of node-positive bladder cancers after radical cystectomy. METHODS: We retrospectively reviewed the data of 75 patients with node-positive bladder cancer after radical cystectomy. Node pathological examination was performed by two experienced uropathologists. Cox regression analysis was performed to identify factors predictive of progression. RESULTS: The median number of removed lymph node was 18 (range 3-49). The median number of positive lymph nodes was 3 (range 1-35). Overall progression-free and cancer-specific survival were 5 and 12 %. In multivariate analysis, ENE, LND with a 20 % cutoff, and adjuvant chemotherapy were independent predictors of progression-free survival (p = 0.007, 0.006, <0.0001). Neither the 2002 nor the 2009 TNM nodal classification was associated with recurrence. CONCLUSIONS: ENE and LND are strong predictors of clinical outcome in patients with node-positive bladder cancer treated by cystectomy. The actual TNM classification could probably be improved using these criteria, allowing better prognostic classification of node-positive bladder cancer after radical cystectomy.

RESUMO

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.

RESUMO

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.

RESUMO

PURPOSE: To review the incidence of UTIs, post-operative fever, and risk factors for post-operative fever in PCNL patients. MATERIALS AND METHODS: Between 2007 and 2009, consecutive PCNL patients were enrolled from 96 centers participating in the PCNL Global Study. Only data from patients with pre-operative urine samples and who received antibiotic prophylaxis were included. Pre-operative bladder urine culture and post-operative fever (>38.5°C) were assessed. Relationship between various patient and operative factors and occurrence of post-operative fever was assessed using logistic regression analyses. RESULTS: Eight hundred and sixty-five (16.2%) patients had a positive urine culture; Escherichia coli was the most common micro-organism found in urine of the 350 patients (6.5%). Of the patients with negative pre-operative urine cultures, 8.8% developed a fever post-PCNL, in contrast to 18.2% of patients with positive urine cultures. Fever developed more often among the patients whose urine cultures consisted of Gram-negative micro-organisms (19.4-23.8%) versus those with Gram-positive micro-organisms (9.7-14.5%). Multivariate analysis indicated that a positive urine culture (odds ratio [OR] = 2.12, CI [1.69-2.65]), staghorn calculus (OR = 1.59, CI [1.28-1.96]), pre-operative nephrostomy (OR = 1.61, CI [1.19-2.17]), lower patient age (OR for each year of 0.99, CI [0.99-1.00]), and diabetes (OR = 1.38, CI [1.05-1.81]) all increased the risk of post-operative fever. Limitations include the use of fever as a predictor of systemic infection. CONCLUSIONS: Approximately 10% of PCNL-treated patients developed fever in the post-operative period despite receiving antibiotic prophylaxis. Risk of post-operative fever increased in the presence of a positive urine bacterial culture, diabetes, staghorn calculi, and a pre-operative nephrostomy.

RESUMO

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.

RESUMO

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.

RESUMO

CONTEXT: Although percutaneous nephrolithotomy (PCNL) has been performed for decades and has gone through many refinements, there are still concerns regarding its more widespread utilization because of the long learning curve and the potential risk of severe complications. Many technical details are not included in the guidelines because of their nature and research protocol. OBJECTIVE: To achieve an expert consensus viewpoint on PCNL indications, preoperative patient preparation, surgical strategy, management and prevention of severe complications, postoperative management, and follow-up. EVIDENCE ACQUISITION: An international panel of experts from the Urolithiasis Section of the European Association of Urology, International Alliance of Urolithiasis, and other urology associations was enrolled, and a prospectively conducted study, incorporating literature review, discussion on research gaps (RGs), and questionnaires and following data analysis, was performed to reach a consensus on PCNL. EVIDENCE SYNTHESIS: The expert panel consisted of 36 specialists in PCNL from 20 countries all around the world. A consensus on PCNL was developed. The expert panel was not as large as expected, and the discussion on RGs did not bring in more supportive evidence in the present consensus. CONCLUSIONS: Adequate preoperative preparation, especially elimination of urinary tract infection prior to PCNL, accurate puncture with guidance of fluoroscopy and/or ultrasonography or a combination, keeping a low intrarenal pressure, and shortening of operation time during PCNL are important technical requirements to ensure safety and efficiency in PCNL. PATIENT SUMMARY: Percutaneous nephrolithotomy (PCNL) has been a well-established procedure for the management of upper urinary tract stones. However, according to an expert panel consensus, core technical aspects, as well as the urologist's experience, are critical to the safety and effectiveness of PCNL.

RESUMO

OBJECTIVE: To determine the proportion of patients who are continent, potent and cancer-free (trifecta rate) 2 years after extraperitoneal laparoscopic radical prostatectomy (ELRP). PATIENTS AND METHODS: We included patients who underwent an ELRP at our department and who were followed for at least 2 years. Those who were impotent or incontinent before the surgery were excluded from the analysis. Overall, 911 men were included. All patients prospectively completed objective, self-administered questionnaires before the medical visit, concerning their voiding and sexual disorders, before surgery and 12 and 24 months after ELRP. Biochemical recurrence was defined as any detectable serum PSA (≥ 0.2 ng/mL). Potency was defined as the ability to achieve an erection sufficient for penetration with or without the use of phosphodiesterase-5 enzyme inhibitor. Urinary continence was defined as absence, or occasional use, of a pad for anticipated vigorous activity. The primary study endpoint was the trifecta rate (cancer control, continence and potency) at 2 years after the surgery. Factors associated with the trifecta outcome were assessed in univariate analysis. RESULTS: Median age and PSA level were 62.2 years and 9.9 ng/mL, respectively. A trifecta outcome was achieved in 29.7 and 54.4% of patients at 12 and 24 months, respectively. The 2-year trifecta rate reached 63.5% in patients undergoing bilateral nerve-sparing surgery and 73.5% in men aged < 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. A total of 84.8% of patients were both cancer-free and continent at 24 months, regardless of erectile function. CONCLUSIONS: Two years after ELRP, the trifecta outcome is achieved in 54.4% of patients who remained potent and continent. This rate reaches 63.5% in patients undergoing a bilateral nerve-sparing procedure. Combined results of good cancer control and continence recovery are reported in 84.8% of patients, regardless of erectile function.

RESUMO

STUDY TYPE: Therapy (case series). LEVEL OF EVIDENCE: 4. What's known on the subject? and What does the study add? Despite excellent surgical cancer control, up to 40% of patients will have biochemical recurrence following radical prostatectomy (RP) for localized prostate cancer. Positive surgical margins (PSM) have been clearly demonstrated to be one of the main predictive factors for biochemical failure, disease progression and cancer mortality. However, decision of further management (adjuvant or salvage therapy) in patients with PSM remains controversial, and many debatable questions arise concerning the incidence of clinical progression and the impact of systematic adjuvant treatment on the cancer specific and overall survival. Analysis of the pathological and disease recurrence outcomes of our large cohort of patients treated by RP provides evidence that PSMs are associated with a poor prognosis in terms of PSA failure and need for salvage therapy. However, such a distinction between negative or positive margin cancers seems to appear clinically less relevant in locally advanced disease with seminal vesicle or high Gleason score≥8 due to the predominant significance of these two poor prognosis factors for prediction of PSA failure. OBJECTIVE: To study the impact of positive surgical margins (PSMs) as an independent predictor of prostate-specific antigen (PSA) failure after radical prostatectomy in adjuvant treatment-naïve patients. PATIENTS AND METHODS: From 2000 to 2008, 1943 men who underwent a radical prostatectomy at Henri Mondor Hospital and who did not receive neoadjuvant or adjuvant therapy were included. Follow-up was recorded into a prospective database. Mean follow-up was 68.8 months. The biochemical recurrence-free survival (RFS), defined by a PSA>0.2 ng/mL, and the need for salvage therapy in univariate and multivariate models, were evaluated. RESULTS: PSA failure was reported in 14.7% and PSMs were noted in 25.6%. In the overall cohort, PSM was significantly predictive for PSA failure (P<0.001; hazard ratio, HR, 2.6), need for salvage therapy (P<0.001; HR, 2.9) and specific deaths (P=0.006; HR, 3.7). The 5-year RFS was 84.4% in men with negative margins compared to 57.5% in the case of PSM. After stratification by pathological stage and Gleason score, margin status was significantly predictive for PSA failure in pT2 (P<0.001), pT3a (P=0.001) and/or Gleason score≤7 cancers (P<0.001), whereas the impact of PSM did not reach significance in pT3b (P=0.196), pT4 (P=0.061) and/or Gleason score≥8 cancers (P=0.115). CONCLUSIONS: PSMs are associated with a poor prognosis in terms of RFS and the need for salvage therapy. Such a distinction between negative or positive margin cancers appears to be clinically less relevant in locally advanced disease with seminal vesicle or high Gleason score (≥8).

RESUMO

OBJECTIVE: • To assess the mid-term (3 years of follow-up) oncological control of laparoscopic radical cystectomy (LRC) for high-grade muscle-invasive bladder cancer in a well studied male population. PATIENTS AND METHODS: • We assessed 40 men with bladder cancer (mean [range] age 66.5 [50-75] years) who underwent LRC and extended pelvic lymphadenectomy at our institution between April 2004 and September 2008. • Of the 40 patients, 13 (32.5%) had a complete laparoscopic procedure (ileal conduit: seven patients; neobladder: five patients; bilateral ureterostomy: one patient) and 27 (67.5%) had an LRC procedure only (ileal conduit: 15 patients; neobladder: 12 patients). RESULTS: • No major complications were observed intraoperatively. • The mean operating time was 407 min and the mean blood loss was 720 mL. Four patients (10%) required conversion to open surgery. The mean (range) hospital stay was 10.2 (7-25) days. One patient died of myocardial infarction in the postoperative period. • Pathological analysis showed organ-confined tumours (stage pT0/pT1/pT2/pT3a) in 22 patients (55%) and extravesical disease (pT3/pT4) in 18 (45%). Of the 40 patients, six (15%) had lymph node involvement. The mean (range) number of nodes removed was 19.9 (5-40). • At a mean (range) follow-up period of 36 (0-72) months, 26 patients were alive with no evidence of disease (disease-free survival rate 67%). CONCLUSION: • Laparoscopic radical cystectomy is a safe, feasible, and effective alternative to open radical cystectomy (ORC). The 3-year oncological efficacy was comparable with that of ORC.

RESUMO

OBJECTIVE: • To investigate the relationship between pretreatment testosterone levels and pathological specimen characteristics, by prospectively examining serum androgen concentrations in a well-studied cohort of patients who underwent radical prostatectomy (RP) for localized prostate cancer. PATIENTS AND METHODS: • A total of 107 patients with clinically localized prostate cancer had an assay of total testosterone before laparoscopic RP at our institution. • The results were classified into two groups based on the total serum testosterone: group1, < 3 ng/mL; group 2, ≥ 3 ng/mL. • Student's t-test was used to compare continuous variables, and Fisher's exact test or the chi-squared test was used to compare categorical variables. • Survival curves were established using the Kaplan-Meier method and compared using the log-rank test. In all tests, P < 0.05 was considered to indicate statistical significance. RESULTS: • All patients had localized prostate cancer based on digital rectal examination (DRE) and preoperative magnetic resonance imaging (MRI). Groups 1 and 2 were similar in terms of age, body mass index, preoperative co-morbidities (cardiovascular and diabetes mellitus), clinical stage of prostate cancer and preoperative PSA levels. • In pathological specimens, low total testosterone (< 3 ng/mL) was an independent risk factor for high Gleason score (> 7) and for locally advanced pathological stage (pT3 and pT4). • Higher preoperative testosterone correlated with disease confined to the gland. • There was no association between serum testosterone levels and surgical margin status, on the one hand, and biochemical recurrence on the other. CONCLUSION: • Low serum testosterone appears to be predictive of aggressive disease (Gleason score >7 and extraprostatic disease, pathological stage > pT2) in patients who underwent RP for localized prostate cancer.

RESUMO

PURPOSE: We aimed to evaluate the impact of the primary Gleason pattern on biochemical recurrence-free survival (RFS) after radical prostatectomy (RP) in a single-center cohort of patients with Gleason 7 tumors. MATERIALS AND METHODS: From 1998 to 2008, 2,239 consecutive patients underwent RP for a localized prostate cancer. A total of 1,248 patients with Gleason score (GS) 7 cancers were included. Follow-up was standardized for all patients and recorded into a prospective database. Median postoperative follow-up was 23.4 months. Biochemical recurrence was defined by prostate-specific antigen level > 0.2 ng/ml. RESULTS: In all, 721 patients (57.8%) had a final GS of 3 + 4 and 527 (42.2%) of 4 + 3. Patients with GS 4 + 3 had a significantly higher risk of biochemical progression than those with GS 3 + 4 (P < 0.001). The 3- and 5-year biochemical RFS for Gleason score 3 + 4 cancers was 84.6 and 76.4%, respectively, versus 69.9 and 61.1% in Gleason score 4 + 3 cancers. Multivariate analysis showed that the primary Gleason remained statistically predictive for PSA failure (P = 0.018). When analysis was stratified by both pathologic stage and margin status, predictive value of primary Gleason was significant in pT2R0, pT3-4R0, and pT3-4R1 cancers, whereas survival curves were not statistically different in pT2R1 cancers (P = 0.672). CONCLUSION: Primary Gleason 4 pattern is an independent predictor for PSA failure. Analysis of Gleason patterns provides clinically relevant prognostic information, which may assist in the management of patients with Gleason score 7 cancers.
