The impact of mpMRI-targeted vs systematic biopsy on the risk of prostate cancer downgrading at final pathology.

PURPOSE: Although targeted biopsies (TBx) are associated with improved disease assessment, concerns have been raised regarding the risk of prostate cancer (PCa) overgrading due to more accurate biopsy core deployment in the index lesion. METHODS: We identified 1672 patients treated with radical prostatectomy (RP) with a positive mpMRI and ISUP ≥ 2 PCa detected via systematic biopsy (SBx) plus TBx. We compared downgrading rates at RP (ISUP 4-5, 3, and 2 at biopsy, to a lower ISUP) for PCa detected via SBx only (group 1), via TBx only (group 2), and eventually for PCa detected with the same ISUP 2-5 at both SBx and TBx (group 3), using multivariable logistic regression models (MVA). RESULTS: Overall, 12 vs 14 vs 6% (n = 176 vs 227 vs 96) downgrading rates were recorded in group 1 vs group 2 vs group 3, respectively (p < 0.001). At MVA, group 2 was more likely to be downgraded (OR 1.26, p = 0.04), as compared to group 1. Conversely, group 3 was less likely to be downgraded at RP (OR 0.42, p < 0.001). CONCLUSIONS: Downgrading rates are highest when PCa is present in TBx only and, especially when the highest grade PCa is diagnosed by TBx cores only. Conversely, downgrading rates are lowest when PCa is identified with the same ISUP through both SBx and TBx. The presence of clinically significant disease at SBx + TBx may indicate a more reliable assessment of the disease at the time of biopsy potentially reducing the risk of downgrading at final pathology.

Prognostic significance of PI-RADS 5 lesions in patients treated by radical prostatectomy.

PURPOSE: To analyse the pathological features and survival of patients with a PI-RADS 5 lesion on pre-biopsy MRI. METHODS: We extracted from a European multicentre prospectively gathered database the data of patients with a PI-RADS 5 lesion on pre-biopsy MRI, diagnosed using both systematic and targeted biopsies and subsequently treated by radical prostatectomy. The Kaplan-Meier model was used to assess the biochemical-free survival of the whole cohort and univariable and multivariable Cox models were set up to study factors associated with survival. RESULTS: Between 2013 and 2019, 539 consecutive patients with a PI-RADS 5 lesion on pre-biopsy MRI were treated by radical prostatectomy and included in the analysis. Follow-up data were available for 448 patients. Radical prostatectomy and lymph node dissection specimens showed non-organ confined disease in 297/539 (55%), (including 2 patients with a locally staged pT2 lesion and lymph node involvement (LNI)). With a median follow-up of 25 months (12-39), the median biochemical recurrence-free survival was 54% at 2 years (95% CI 45-61) and 28% at 5 years (95% CI 18-39). Among the factors studied, MRI T stage [T3a vs T2 HR 3.57 (95%CI 1.78-7.16); T3b vs T2 HR 6.17 (95% CI 2.99-12.72)] and PSA density (HR 4.47 95% CI 1.55-12.89) were significantly associated with a higher risk of biochemical recurrence in multivariable analysis. CONCLUSION: Patients with a PI-RADS 5 lesion on pre-biopsy MRI have a high risk of early biochemical recurrence after radical prostatectomy. MRI T stage and PSA density can be used to improve patient selection and counselling.

European Association for Endoscopic Surgery (EAES) consensus on Indocyanine Green (ICG) fluorescence-guided surgery.

BACKGROUND: In recent years, the use of Indocyanine Green (ICG) fluorescence-guided surgery during open and laparoscopic procedures has exponentially expanded across various clinical settings. The European Association of Endoscopic Surgery (EAES) initiated a consensus development conference on this topic with the aim of creating evidence-based statements and recommendations for the surgical community. METHODS: An expert panel of surgeons has been selected and invited to participate to this project. Systematic reviews of the PubMed, Embase and Cochrane libraries were performed to identify evidence on potential benefits of ICG fluorescence-guided surgery on clinical practice and patient outcomes. Statements and recommendations were prepared and unanimously agreed by the panel; they were then submitted to all EAES members through a two-rounds online survey and results presented at the EAES annual congress, Barcelona, November 2021. RESULTS: A total of 18,273 abstracts were screened with 117 articles included. 22 statements and 16 recommendations were generated and approved. In some areas, such as the use of ICG fluorescence-guided surgery during laparoscopic cholecystectomy, the perfusion assessment in colorectal surgery and the search for the sentinel lymph nodes in gynaecological malignancies, the large number of evidences in literature has allowed us to strongly recommend the use of ICG for a better anatomical definition and a reduction in post-operative complications. CONCLUSIONS: Overall, from the systematic literature review performed by the experts panel and the survey extended to all EAES members, ICG fluorescence-guided surgery could be considered a safe and effective technology. Future robust clinical research is required to specifically validate multiple organ-specific applications and the potential benefits of this technique on clinical outcomes.

EAU-ESMO consensus statements on the management of advanced and variant bladder cancer-an international collaborative multi-stakeholder effort: under the auspices of the EAU and ESMO Guidelines Committees†.

BACKGROUND: Although guidelines exist for advanced and variant bladder cancer management, evidence is limited/conflicting in some areas and the optimal approach remains controversial. OBJECTIVE: To bring together a large multidisciplinary group of experts to develop consensus statements on controversial topics in bladder cancer management. DESIGN: A steering committee compiled proposed statements regarding advanced and variant bladder cancer management which were assessed by 113 experts in a Delphi survey. Statements not reaching consensus were reviewed; those prioritised were revised by a panel of 45 experts before voting during a consensus conference. SETTING: Online Delphi survey and consensus conference. PARTICIPANTS: The European Association of Urology (EAU), the European Society for Medical Oncology (ESMO), experts in bladder cancer management. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Statements were ranked by experts according to their level of agreement: 1-3 (disagree), 4-6 (equivocal), 7-9 (agree). A priori (level 1) consensus was defined as ≥70% agreement and ≤15% disagreement, or vice versa. In the Delphi survey, a second analysis was restricted to stakeholder group(s) considered to have adequate expertise relating to each statement (to achieve level 2 consensus). RESULTS AND LIMITATIONS: Overall, 116 statements were included in the Delphi survey. Of these, 33 (28%) statements achieved level 1 consensus and 49 (42%) statements achieved level 1 or 2 consensus. At the consensus conference, 22 of 27 (81%) statements achieved consensus. These consensus statements provide further guidance across a broad range of topics, including the management of variant histologies, the role/limitations of prognostic biomarkers in clinical decision making, bladder preservation strategies, modern radiotherapy techniques, the management of oligometastatic disease and the evolving role of checkpoint inhibitor therapy in metastatic disease. CONCLUSIONS: These consensus statements provide further guidance on controversial topics in advanced and variant bladder cancer management until a time where further evidence is available to guide our approach.

A multicentric study on accurate grading of prostate cancer with systematic and MRI/US fusion targeted biopsies: comparison with final histopathology after radical prostatectomy.

OBJECTIVE: To evaluate the accuracy in histologic grading of MRI/US image fusion biopsy by comparing histopathology between systematic biopsies (SB), targeted biopsies (TB) and the combination of both (SB + TB) with the final histopathologic outcomes of radical prostatectomy specimens. MATERIALS AND METHODS: Retrospective, multicentric study of 443 patients who underwent SB and TB using MRI/US fusion technique (Urostation® and Trinity®) prior to radical prostatectomy between 2010 and 2017. Cochran's Q test and McNemar test were conducted as a post hoc test. Uni-multivariable analyses were performed on several clinic-pathological variables to analyze factors predicting histopathological concordance for targeted biopsies. RESULTS: Concordance in ISUP (International Society of Urological Pathology) grade between SB, TB and SB + TB with final histopathology was 49.4%, 51.2%, and 63.2% for overall prostate cancer and 41.2%, 48.3%, and 56.7% for significant prostate cancer (ISUP grade ≥ 2), respectively. Significant difference in terms of concordance, downgrading and upgrading was found between SB and TB (ISUP grade ≥ 2 only), SB and SB + TB, TB and SB + TB (overall ISUP grade and ISUP grade ≥ 2) (p < 0.001). Total number of cores and previous biopsies were significant independent predictive factors for concordance with TB technique. CONCLUSION: In this retrospective study, combination of SB and TB significantly increased concordance with final histopathology despite a limited additional number of cores needed.

Recurrence, progression and cancer-specific mortality according to stage at re-TUR in T1G3 bladder cancer patients treated with BCG: not as bad as previously thought.

PURPOSE: The goals of transurethral resection of a bladder tumor (TUR) are to completely resect the lesions and to make a correct diagnosis to adequately stage and treat the patient. Persistent disease after TUR is not uncommon and is why re-TUR is recommended in T1G3 patients. When there is T1 tumor in the re-TUR specimen, very high risks of progression (82%) have been reported. We analyze the risks of recurrence, progression to muscle-invasive disease and cancer-specific mortality (CSM) according to tumor stage at re-TUR in T1G3 patients treated with BCG. METHODS: In our retrospective cohort of 2451 T1G3 patients, 934 patients (38.1%) underwent re-TUR. 667 patients had residual disease (71.4%): Ta in 378 (40.5%), T1 in 289 (30.9%) patients. Times to recurrence, progression and CSM in the three groups were estimated using cumulative incidence functions and compared using the Cox regression model. RESULTS: During a median follow-up of 5.2 years, 512 patients recurred. The recurrence rate was significantly higher in patients with a T1 at re-TUR (P < 0.001). Progression rates differed according to the pathology at re-TUR, 25.3% in T1, 14.6% in Ta and 14.2% in case of no residual tumor (P < 0.001). Similar trends were seen in both patients with and without muscle in the original TUR specimen. CONCLUSIONS: Patients with T1G3 tumors and no residual disease or Ta at re-TUR have better recurrence, progression and CSM rates than previously reported, with a CSM rate of 13.1 and a 25.3% progression rate in re-TUR T1 disease.

Older patients with low Charlson score and high-risk prostate cancer benefit from radical prostatectomy.

INTRODUCTION: The aim of the study was to identify the appropriate level of Charlson comorbidity index (CCI) in older patients (>70 years) with high-risk prostate cancer (PCa) to achieve survival benefit following radical prostatectomy (RP). METHODS: We retrospectively analyzed 1008 older patients (>70 years) who underwent RP with pelvic lymph node dissection for high-risk prostate cancer (preoperative prostate-specific antigen >20 ng/mL or clinical stage ≥T2c or Gleason ≥8) from 14 tertiary institutions between 1988 and 2014. The study population was further grouped into CCI < 2 and ≥2 for analysis. Survival rate for each group was estimated with Kaplan-Meier method and competitive risk Fine-Gray regression to estimate the best explanatory multivariable model. Area under the curve (AUC) and Akaike information criterion were used to identify ideal 'Cut off' for CCI. RESULTS: The clinical and cancer characteristics were similar between the two groups. Comparison of the survival analysis using the Kaplan-Meier curve between two groups for non-cancer death and survival estimations for 5 and 10 years shows significant worst outcomes for patients with CCI ≥ 2. In multivariate model to decide the appropriate CCI cut-off point, we found CCI 2 has better AUC and p value in log rank test. CONCLUSION: Older patients with fewer comorbidities harboring high-risk PCa appears to benefit from RP. Sicker patients are more likely to die due to non-prostate cancer-related causes and are less likely to benefit from RP.

Early diagnosis of bladder cancer through the detection of urinary tyrosine-phosphorylated proteins.

BACKGROUND: A noninvasive, highly sensitive and specific urine test is needed for bladder cancer (BC) diagnosis and surveillance in addition to the invasive cystoscopy. We previously described the diagnostic effectiveness of urinary tyrosine-phosphorylated proteins (UPY) and a new assay (UPY-A) for their measurement in a pilot study. The aim of this work was to evaluate the performances of the UPY-A using an independent cohort of 262 subjects. METHODS: Urinary tyrosine-phosphorylated proteins were measured by UPY-A test. The area under ROC curve, cutoff, sensitivity, specificity and predictive values of UPY-A were determined. The association of UPY levels with tumour staging, grading, recurrence and progression risk was analysed by Kruskal-Wallis and Wilcoxon's test. To test the probability to be a case if positive at the UPY-A, a logistic test adjusted for possible confounding factor was used. RESULTS: Results showed a significant difference of UPY levels between patients with BC vs healthy controls. For the best cutoff value, 261.26 Standard Units (SU), the sensitivity of the assay was 80.43% and the specificity was 78.82%. A statistically significant difference was found in the levels of UPY at different BC stages and grades between Ta and T1 and with different risk of recurrence and progression. A statistically significant increased risk for BC at UPY-A ⩾261.26 SU was observed. CONCLUSIONS: The present study supplies important information on the diagnostic characteristics of UPY-A revealing remarkable performances for early stages and allowing its potential use for different applications encompassing the screening of high-risk subjects, primary diagnosis and posttreatment surveillance.

The clinical use of statistical permutation test methodology: a tool for identifying predictive variables of outcome.

OBJECTIVES: To identify the predictive variables affecting the outcome after radical surgery for bladder cancer by a newer statistical methodology, i.e. nonparametric combination (NPC). METHODS: A multicenter study enrolled 1,312 patients who had undergone radical cystectomy for bladder cancer in 11 Italian oncological centers from January 1982 to December 2002. A statistical analysis of their medical history and diagnostic, pathological and postoperative variables was performed using a NPC test. The patients were included in a comprehensive database with medical history and clinical and pathological data. Five-year survival was used as the dependent variable, and p values were corrected for multiplicity using a closed testing procedure. The newer nonparametric approach was used to evaluate the prognostic importance of the variables. All of the analyses were performed using routines developed in MATLAB© and the significance level was set at α = 0.05. RESULTS: A significant prognostic predictive value (p < 0.01) for tumor clinical staging, hydronephrosis, tumor pathological staging, grading, presence of concomitant carcinoma in situ, regional lymph node involvement, corpora cavernosa invasion, microvascular invasion, lymphatic invasion and prostatic stroma involvement was found. CONCLUSIONS: The NPC test could handle any type of variable (categorical and quantitative) and take into account the multivariate relation among variables. This newer methodology offers a significant contribution in biomedical studies with several endpoints and is recommended in presence of non-normal data and missing values, as well as solving high-dimensional data and problems relating to small sample sizes.

Transperineal versus transrectal prostate biopsy for predicting the final laterality of prostate cancer: are they reliable enough to select patients for focal therapy? Results from a multicenter international study.

OBJECTIVES: To compare the concordance of prostate cancer (PCa) laterality between the extended transperineal (TP) or transrectal (TR) prostate biopsy (BP) and radical prostatectomy (RP) specimens. To identify predictors of laterality agreement between BP and RP. MATERIALS AND METHODS: Data from 533 consecutive patients with PCa (278 TP and 255 TR-diagnosed) treated with RP were analyzed. A 12-core technique was used for both TP and TR biopsies. Additional cores were obtained when necessary. RESULTS: Overall, the percentage of agreement of PCa laterality between BP and RP was 60% (K = 0.27, p < 0.001). However, the RP confirmation of unilaterality at BP was obtained in just 33% of the cases. Considering the concordance on bilaterality as the ″target″ of our analysis, the sensitivity and specificity were 54.3% and 98.2% , respectively, with TP and 47.5% and 92.5%, respectively with TR. Focusing on patients with unilaterality at biopsy, none of the evaluated preoperative variables (biopsy technique, age, total positive biopsy cores, PSA, prostate volume, Gleason score on biopsy) were able to predict RP bilaterality in the multivariate analyses. CONCLUSIONS: Most of the patients with unilateral involvement at BP harbored bilateral PCa after RP. TR and TP biopsy showed no difference in their capacity to predict the concordance of tumor laterality at RP. None of the preoperative evaluated variables can predict the tumor laterality at RP. Using BP unilaterality to include patients in focal therapy (FT) protocols may hinder the oncologic efficacy of FT.

The current role of precision surgery in oligometastatic prostate cancer.

Oligometastatic prostate cancer (omPCa) is a novel intermediate disease state characterized by a limited volume of metastatic cells and specific locations. Accurate staging is paramount to unmask oligometastatic disease, as provided by prostate-specific membrane antigen-positron emission tomography. Driven by the results of prospective trials employing conventional and/or modern staging modalities, the treatment landscape of omPCa has rapidly evolved over the last years. Several treatment-related questions comprising the concept of precision strikes are under development. For example, beyond systemic therapy, cohort studies have found that cytoreductive radical prostatectomy (CRP) can confer a survival benefit in select patients with omPCa. More importantly, CRP has been consistently shown to improve long-term local symptoms when the tumor progresses across disease states due to resistance to systemic therapies. Metastasis-directed treatments have also emerged as a promising treatment option due to the visibility of oligometastatic disease and new technologies as well as treatment strategies to target the novel PCa colonies. Whether metastases are present at primary cancer diagnosis or detected upon biochemical recurrence after treatment with curative intent, targeted yet decisive elimination of disseminated tumor cell hotspots is thought to improve survival outcomes. One such strategy is salvage lymph node dissection in oligorecurrent PCa which can alter the natural history of progressive PCa. In this review, we will highlight how refinements in modern staging modalities change the classification and treatment of (oligo-)metastatic PCa. Further, we will also discuss the current role and future directions of precision surgery in omPCa.

Radical Nephroureterectomy Tetrafecta: A Proposal Reporting Surgical Strategy Quality at Surgery.

Background: Standardized methods for reporting surgical quality have been described for all the major urological procedures apart from radical nephroureterectomy (RNU). Objective: To propose a tetrafecta criterion for assessing the quality of RNU based on a consensus panel within the Young Association of Urology (YAU) Urothelial Group, and to test the impact of this tetrafecta in a multicenter, large contemporary cohort of patients treated with RNU for upper tract urothelial carcinoma (UTUC). Design setting and participants: This was a retrospective analysis of 1765 patients with UTUC treated between 2000 and 2021. Outcome measurements and statistical analysis: We interviewed the YAU Urothelial Group to propose and score a list of items to be included in the "RNU-fecta." A ranking was generated for the criteria with the highest sum score. These criteria were applied to a large multicenter cohort of patients. Kaplan-Meier curves were built to evaluate differences in overall survival (OS) rates between groups, and a multivariable logistic regression model was used to find the predictors of achieving the RNU tetrafecta. Results and limitations: The criteria with the highest score included three surgical items such as negative soft tissue surgical margins, bladder cuff excision, lymph node dissection according to guideline recommendations, and one oncological item defined by the absence of any recurrence in ≤12 mo. These items formed the RNU tetrafecta. Within a median follow-up of 30 mo, 52.6% of patients achieved the RNU tetrafecta. The 5-yr OS rates were significantly higher for patients achieving tetrafecta than for their counterparts (76% vs 51%). Younger age, lower body mass index, and robotic approach were found to be independent predictors of tetrafecta achievement. Conversely, a higher Eastern Cooperative Oncology Group score, higher clinical stage, and bladder cancer history were inversely associated with tetrafecta. Conclusions: Herein, we present a "tetrafecta" composite endpoint that may serve as a potential tool to assess the overall quality of the RNU procedure. Pending external validation, this tool could allow a comparison between surgical series and may be useful for assessing the learning curve of the procedure as well as for evaluating the impact of new technologies in the field. Patient summary: In this study, a tetrafecta criterion was developed for assessing the surgical quality of radical nephroureterectomy in patients with upper tract urothelial carcinoma. Patients who achieved tetrafecta had higher 5-yr overall survival rates than those who did not.

Radiofrequency ablation for the treatment of small renal masses: safety and oncologic efficacy.

The successful introduction of radio frequency ablation (RFA) into various surgical fields has fueled the interest of the urological community to study its application in small renal masses (SRM). However, some controversies remain regarding its oncologic efficacy. In this paper, we review the complication rates and highlight local ablative success and long-term oncologic outcomes of recent, larger RFA series. Review of the recent literature (Medline from January 2003 through May 2011 with the terms ("radiofrequency ablation" OR "catheter ablation") AND ("renal cell carcinoma" OR "renal tumor" OR "renal mass" OR "renal cancer" OR "kidney cancer"). Twelve RFA studies including a minimum of 35 treated tumors, and representing 717 patients were identified and analyzed for local ablative success rates and complications. Reported complications were classified according to Dindo-Clavien. Another five studies representing 172 patients were identified to assess long-term oncologic outcomes. Final pathology revealed 82.3% biopsy-proven renal cell carcinomas (RCCs) in 8 of the 12 evaluable RFA studies. Local ablative success rates after a first RFA session ranged from 67% to 100%. However, accepting a 8.8% repeat ablation rate, final success rates were 89.7-100%, with 7 of 12 studies showing final ablative success in >95%. These results demonstrate RFA to achieve adequate local tumor control regardless of histology. Risk of complications was 13.2%. Of complications, 10% were minor (grade I or II), while only 3.2% were major complications (grade ≥III). Five papers were identified describing oncological outcome at a minimum follow-up of 53 months (range 53-61.2). Progression-free survival, cancer-specific survival and overall survival ranged from 79.9 to 93.8%, 98 to 100% and 58.3 to 85%, respectively. This literature review confirms that RFA can deliver durable local tumor control and excellent long-term oncological outcomes. However, in order to achieve this, a repeat ablation rate of 8.8% has to be accepted. Complication rates are low, with 10% grade I-II and only 3.2% grade >III. These observations render RFA an attractive alternative to surgery in an elderly or comorbid population.

Risk factors for residual disease at re-TUR in a large cohort of T1G3 patients.

INTRODUCTION AND OBJECTIVES: The goals of transurethral resection of a bladder tumor (TUR) are to completely resect the lesions and to make a correct diagnosis in order to adequately stage the patient. It is well known that the presence of detrusor muscle in the specimen is a prerequisite to minimize the risk of under staging. Persistent disease after resection of bladder tumors is not uncommon and is the reason why the European Guidelines recommended a re-TUR for all T1 tumors. It was recently published that when there is muscle in the specimen, re-TUR does not influence progression or cancer specific survival. We present here the patient and tumor factors that may influence the presence of residual disease at re-TUR. MATERIAL AND METHODS: In our retrospective cohort of 2451 primary T1G3 patients initially treated with BCG, pathology results for 934 patients (38.1%) who underwent re-TUR are available. 74% had multifocal tumors, 20% of tumors were more than 3 cm in diameter and 26% had concomitant CIS. In this subgroup of patients who underwent re-TUR, there was no residual disease in 267 patients (29%) and residual disease in 667 patients (71%): Ta in 378 (40%) and T1 in 289 (31%) patients. Age, gender, tumor status (primary/recurrent), previous intravesical therapy, tumor size, tumor multi-focality, presence of concomitant CIS, and muscle in the specimen were analyzed in order to evaluate risk factors of residual disease at re-TUR, both in univariate analyses and multivariate logistic regressions. RESULTS: The following were not risk factors for residual disease: age, gender, tumor status and previous intravesical chemotherapy. The following were univariate risk factors for presence of residual disease: no muscle in TUR, multiple tumors, tumors > 3 cm, and presence of concomitant CIS. Due to the correlation between tumor multi-focality and tumor size, the multivariate model retained either the number of tumors or the tumor diameter (but not both), p < 0.001. The presence of muscle in the specimen was no longer significant, while the presence of CIS only remained significant in the model with tumor size, p < 0.001. CONCLUSIONS: The most significant factors for a higher risk of residual disease at re-TUR in T1G3 patients are multifocal tumors and tumors more than 3 cm. Patients with concomitant CIS and those without muscle in the specimen also have a higher risk of residual disease.

Elastic fusion biopsy versus systematic biopsy for prostate cancer detection: Results of a multicentric study on 1,119 patients. / Evaluación de la biopsia de fusión elástica vs. biopsia sistemática para la detección del cáncer de próstata: resultados de un estudio multicéntrico en 1.119 pacientes.

OBJECTIVES: To assess the accuracy of targeted and systematic biopsies for the detection of prostate cancer (PCa) and clinically significant PCa (csPCa) in the everyday practice, evaluating the need for additional systematic biopsies at the time of targeted biopsy. PATIENTS AND METHODS: From our multicentric database gathering data on 2,115 patients who underwent fusion biopsy with Koelis™ system between 2010 and 2017, we selected 1,119 patients who received targeted biopsies (a median of 3 for each target), followed by systematic sampling of the prostate (12 to 14 cores). Overall and clinically significant cancer detection rate (CDR) of Koelis™ fusion biopsies were assessed, comparing target and systematic biopsies. Secondary endpoint was the identification of predictors of PCa detection. RESULTS: The CDR of targeted biopsies only was 48% for all cancers and 33% for csPCa. The performance of additional, systematic prostate sampling improved the CDR of 15% for all cancers and of 12% for csPCa. PCa was detected in 35%, 69%, and 92% of patients with lesions scored as PI-RADS 3, 4 and 5, respectively. Elevated PI-RADS score and positive digital rectal examination were predictors of PCa, whereas biopsy-naïve status was associated with csPCa. CONCLUSION: In the everyday practice target biopsy with Koelis™ achieves a good CDR for all PCa and csPCa, which is significantly improved by subsequent systematic sampling of the prostate. The outstanding outcomes of fusion biopsy are confirmed also in biopsy-naïve patients. Elevated PI-RADS score and positive digital rectal examination are strongly associated with presence of PCa.

Proposal of an improved prognostic classification for pT3 renal cell carcinoma.

PURPOSE: The prognostic accuracy of the current TNM 2002 staging system for locally advanced renal cell carcinoma has been questioned. To contribute to the development of a more accurate classification for this stage of disease we assessed the correlation between patterns of invasion in the pT3 category and outcomes in a large multi-institutional series. MATERIALS AND METHODS: Pathological data and clinical followup on 513 pT3 renal cell carcinoma cases treated with radical nephrectomy between 1983 and 2005 at 3 Italian academic centers were retrospectively reviewed. Cause specific survival rates were calculated with the Kaplan-Meier method and multivariate analysis was performed using the Cox proportional hazards regression model. RESULTS: Estimated overall 5-year cause specific survival was 50.1% at a median followup of 61.5 months in survivors. The current TNM classification was not a significant outcome prognosticator. Patients with a tumor invading only the perirenal or sinus fat were at lowest risk for death from the disease. Patients at intermediate risk had tumors with invasion of the venous system alone. Simultaneous perirenal fat and sinus fat invasion or perirenal fat and vascular invasion as well as adrenal gland involvement characterized high risk tumors. Low risk tumors could be further divided into 2 groups with different outcomes based on a size cutoff of 7 cm. Our classification was a significant predictor of survival on multivariate analysis as well as M stage, N stage, Fuhrman grade and tumor size. CONCLUSIONS: We confirm that the prognostic usefulness of the current 2002 TNM system for pT3 renal cell carcinoma is limited. We have identified 4 groups of tumors with distinct patterns of invasion and significantly different survival probabilities in this category. Large prospective series are needed to validate these findings.

Sexual function in women undergoing hemodialytic treatment assessed using the female sexual function index (FSFI) and the somatic inkblot series (SIS) test.

AIMS: Female sexuality in end-stage renal disease has so far only been explored using non-validated tools. The aim of this study was to compare sexual function among hemodialyzed (HD) patients and healthy controls using validated questionnaires. MATERIAL: Two internationally validated tests have been administrated: the female sexual function index (FSFI) questionnaire and a set of tables from the somatic inkblot series (SIS) test which focus specifically on the area of sexuality. METHODS: 25 consecutive HD patients were assessed for sexual function using the FSFI. Nine SIS inkblots concerning sexuality were also administered to obtain more detailed information about the psychological component of sexuality. An equal number of control healthy volunteers perfectly matched for age, marital status and educational level underwent the same evaluations, and the results of the two groups were compared. RESULTS: HD patients had significantly lower scores than the controls for all FSFI domains except sexual desire even when stratified by age and marital status. All sexually related thematic areas of the SIS except body perception were significantly affected in the HD group compared to the control group. CONCLUSIONS: Chronic renal failure requiring HD treatment adversely affects female sexual function. The psychological impact on patients is significant when compared to an age-matched control group. Both the FSFI questionnaire and the SIS test may be considered useful tools for an integrated medical and psychological screening of FSD.

Transobturator tape in the management of female stress incontinence: clinical outcomes at medium term follow-up.

OBJECTIVE: To assess the efficacy of transobturator tape (TOT) in the management of stress urinary incontinence at a medium term follow-up. METHODS: TOT is a polypropylene tape positioned through the obturator foramen. 70 patients with type II urinary stress incontinence were treated with TOT between June 2003 and May 2006. Patients were prospectively studied by physical examination, quality of life questionnaire (I-QOL), visual analog scale, global impression (dry, improved, same, worse), preoperative urodynamic study, and pre- and postoperative flowmetry. Statistical analysis (t test) of the difference in I-QOL scores and flowmetry was made by StatSoft V. 5.1. RESULTS: The average follow-up was 32 (range 12-48) months. The I-QOL score increased statistically significantly by 40 points. The average percent improvement was 80%. 90% (63/70) of the patients were dry and 5% (4/70) were improved. The pre- and postoperative uroflowmetry studies were not statistically different. Vaginal erosion occurred in 4 patients. CONCLUSION: TOT is a safe procedure with a good efficacy at 32-month follow-up.

Treatment options and predictive factors for recurrence and cancer-specific mortality in bladder cancer after renal transplantation: A multi-institutional analysis. / Opciones terapéuticas y factores predictivos de recurrencia y mortalidad cáncer-específica en pacientes con tumor vesical después de trasplante renal: análisis multiinstitucional.

OBJECTIVES: Bladder cancer (BC) in the transplanted population can represent a challenge owing to the immunosuppressed state of patients and the higher rate of comorbidities. The objective was to analyze the treatment of BC after renal transplant (RT), focusing on the mode of presentation, diagnosis, treatment options and predictive factors for recurrence. MATERIAL AND METHODS: We conducted an observational prospective study with a retrospective analysis of 88 patients with BC after RT at 10 European centers. Clinical and oncologic data were collected, and indications and results of adjuvant treatment reviewed. The Kaplan-Meier method and uni- and multivariate Cox regression analyses were performed. RESULTS: A total of 10,000 RTs were performed. Diagnosis of BC occurred at a median of 73 months after RT. Median follow-up was 126 months. Seventy-one patients (81.6%) had non-muscle invasive bladder cancer, of whom 29 (40.8%) received adjuvant treatment; of these, six (20.6%) received bacillus Calmette-Guérin and 20 (68.9%) mitomycin C. At univariate analysis, patients who received bacillus Calmette-Guérin had a significantly lower recurrence rate (P=.043). At multivariate analysis, a switch from immunosuppression to mTOR inhibitors significantly reduced the risk of recurrence (HR 0.24, 95% CI: 0.053-0.997, P=.049) while presence of multiple tumors increased it (HR 6.31, 95% CI: 1.78-22.3, P=.004). Globally, 26 patients (29.88%) underwent cystectomy. No major complications were recorded. Overall mortality (OM) was 32.2% (28 patients); the cancer-specific mortality was 13.8%. CONCLUSIONS: Adjuvant bacillus Calmette-Guérin significantly reduces the risk of recurrence, as does switch to mTOR inhibitors. Multiple tumors increase the risk.
