Background: To investigate the impact of COVID-19 outbreak on the diagnosis and treatment of non-muscle invasive bladder cancer (NMIBC). Methods: A retrospective analysis was performed using an Italian multi-institutional database of TURBT patients with high-risk urothelial NMIBC between January 2019 and February 2021, followed by Re-TURBT and/or adjuvant intravesical BCG. Results: A total of 2591 patients from 27 institutions with primary TURBT were included. Of these, 1534 (59.2%) and 1056 (40.8%) underwent TURBT before and during the COVID-19 outbreak, respectively. Time between diagnosis and TURBT was significantly longer during the COVID-19 period (65 vs. 52 days, p = 0.002). One thousand and sixty-six patients (41.1%) received Re-TURBT, 604 (56.7%) during the pre-COVID-19. The median time to secondary resection was significantly longer during the COVID-19 period (55 vs. 48 days, p &lt, 0.0001). A total of 977 patients underwent adjuvant intravesical therapy after primary or secondary resection, with a similar distribution across the two groups (n = 453, 86% vs. n = 388, 86.2%). However, the proportion of the patients who underwent maintenance significantly differed (79.5% vs. 60.4%, p &lt, 0.0001). Conclusions: The COVID-19 pandemic represented an unprecedented challenge to our health system. Our study did not show significant differences in TURBT quality. However, a delay in treatment schedule and disease management was observed. Investigation of the oncological impacts of those differences should be advocated.

Introduction We aimed to test the hypothesis that the immune-modulatory effect of statins may improve survival outcomes in patients with non-muscle invasive bladder cancer (NMIBC). We focused on a cohort of patients diagnosed with high risk NMIBC, that were treated with intravesical BCG immunotherapy. Patients and methods We included patients at first diagnosis of T1 high grade NMIBC after transurethral resection of bladder (TURB). All procedures were performed at 18 different tertiary institutions between January 2002 and December 2012. Univariable and multivariable models were used to test differences in terms of residual tumour, disease recurrence, disease progression and overall mortality (OM) rates. Results Overall, 1510 patients with T1 high grade NMIBC at TURB were included in our analyses. Of these, 402 (26.6%) were statin users. At multivariable analysis, statin use was associated with a higher rates of high grade BC at re-TURB (OR: 1.37, 95%CI: 1.04-1.78; p=0.022), while at follow-up it was not independently associated with OM (HR: 0.71, 95%CI: 0.50-1.03; p=0.068) and disease progression rates (HR: 0.97, 95%CI: 0.79-1.19; p=0.753). Conversely, statin use has been shown to be independently associated with a lower risk of recurrence (HR:0.80, 95%CI: 0.67-0.95; p=0.009). The median recurrence-free survival was 47 (95%CI 40-49) months for those classified as non-statin users vs. 53 (95%CI 48-68) months in those classified as statin users. Conclusions Statin daily intake do not compromise oncological outcomes in high risk NMIBC patients treated with BCG. Moreover, statin may have a beneficial effect on recurrence rates in this cohort of patients.

BACKGROUND: There are sex differences in vulnerability to Coronavirus disease 2019 (COVID-19). The coronavirus S protein mediates viral entry into target cells employing the host cellular serine protease TMPRSS2 for S-protein priming. The TMPRSS2 gene expression is responsive to androgen stimulation and it could partially explain sex differences. We hypothesized that men chronically exposed to 5-alpha reductase inhibitors (5ARIs) for benign prostate hyperplasia (BPH) have a lower risk of hospitalization for COVID-19. METHODS: This is a population-based case-control study on consecutive patients positive for SARS-CoV-2 virus who required hospitalization for COVID-19 (cases), age-matched to beneficiaries of the Lombardy Regional Health Service (controls). Data were collected by two high-volume COVID-19 regional centers of Lombardy (Italy). The primary outcome was to compare the prevalence of patients chronically exposed to 5ARIs, who required hospitalization for COVID-19, with the one of controls. RESULTS: Overall, 943 males were enrolled; 45 (4.77%) were exposed to 5ARI. COVID-19 patients aged >55 years under 5ARI treatment were significantly less than expected on the basis of the prevalence of 5ARI treatment among age-matched controls (5.57 vs. 8.14%; p=0.0083, 95%CI=0.75-3.97%). This disproportion was higher for men aged >65 (7.14 vs. 12.31%; p=0.0001, 95%CI=2.83-6.97%). Eighteen 5ARIs-patients died; the mean age of men who died was higher than those who did not: 75.98±9.29 vs. 64.78±13.57 (p

Background An accurate and early diagnosis of bladder cancer (BC) is essential to offer patients the most appropriate treatment and the highest cure rate. For this reason, patients need to be best stratified by class and risk factors. We aimed to develop a score able to better predict cancer outcomes, using serum variables of inflammation. Methods A total of 1,510 high-risk non-muscle invasive bladder cancer (NMIBC) patients were included in this retrospective observational study. Patients with pathologically proven T1 HG/G3 at first TURBT were included. Systemic combined inflammatory score (SCIS) was calculated according to systemic inflammatory markers (SIM), modified Glasgow prognostic score (mGPS), and prognostic nutritional index (PNI) dichotomized (final score from 0 to 3). Results After 48 months of follow-up (IQR 40.0-73.0), 727 patients recurred (48.1%), 485 progressed (32.1%), 81 died for cancer (7.0%), and 163 died for overall causes (10.8%). Overall, 231 (15.3%) patients had concomitant Cis, 669 (44.3%) patients had multifocal pathology, 967 (64.1%) patients had tumor size >3 cm. Overall, 357 (23.6%) patients received immediate-intravesical therapy, 1,356 (89.8%) received adjuvant intravesical therapy, of which 1,382 (91.5%) received BCG, 266 (17.6%) patients received mitomycin C, 4 (0.5%) patients received others intravesical therapy. Higher SCIS was independently predictive of recurrence (hazard ratio HR 1.5, 1.3 and 2.2) and cancer specific mortality for SCIS 0 and 3 (HR: 1.61 and 2.3), and overall mortality for SCIS 0 and 3 (HR: 2.4 and 3.2). Conversely, SCIS was not associated with a higher probability of progression. Conclusions The inclusion of the SCIS in clinical practice is simple to apply and can help improve the prediction of cancer outcomes. It can identify patients with high-grade BC who are more likely to experience disease mortality.

Objective: Overview of bladder cancer (BC) management in Italy during the first month of the COVID-19 pandemic (March 2020) with head to head comparison of the data from March 2019, considered “usual activity” period. The aim is to analyze performance of different Italian Centers in North, Center and South, with a special eye for Lombardy (the Italian epicenter). Patients and methods: During April 2020, a survey containing 14 multiple-choice questions focused on general staffing and surgical activity related to BC during the months of March 2019 and March 2020 was sent to 32 Italian Centers. Statistical analysis was performed using IBM SPSS Statistics (v26) software. A Medline search was performed, in order to attempt a comparative analysis with published papers. Results: 28 Centers answered, for a response rate of 87.5%. Most of the urology staff in the Lombardy region were employed in COVID wards (p = 0.003), with a statistically significant reduction in the number of radical cystectomies (RC) performed during that time (p = 0.036). The total amount of RC across Italy remained the same between 2019 and 2020, however there was an increase in the number of surgeries performed in the Southern region. This was most likely due to travel restrictions limiting travel the North. The number of Trans-Urethral Resection of Bladder Tumors (TURBT) (p = 0.046) was higher in Academic Centers (AC) in 2020 (p = 0.037).Conclusions: The data of our survey, although limited, represents a snap shot of the management of BC during the first month of the COVD-19 pandemic, which posed a major challenge for cancer centers seeking to provide care during an extremely dynamic clinical and political situation which requires maximum flexibility to be appropriately managed.

Background: The new severe acute respiratory syndrome virus (SARS-CoV-2) outbreak is a huge health, social and economic issue and has been declared a pandemic by the World Health Organization. Bladder cancer, on the contrary, is a well-known disease burdened by a high rate of affected patients and risk of recurrence, progression and death. Summary: The coronavirus disease (COVID-19 or 2019-nCoV) often involves mild clinical symptoms but in some cases, it can lead to pneumonia with acute respiratory distress syndrome and multiorgan dysfunction. Factors associated with developing a more severe disease are increased age, obesity, smoking and chronic underlying comorbidities (including diabetes mellitus). High-risk non-muscle-invasive bladder cancer (NMIBC) progression and worse prognosis are also characterized by a higher incidence in patients with risk factors similar to COVID-19. Immune system response and inflammation have been found as a common hallmark of both diseases. Most severe cases of COVID-19 and high-risk NMIBC patients at higher recurrence and progression risk are characterized by innate and adaptive immune activation followed by inflammation and cytokine/chemokine storm (interleukin [IL]-2, IL-6, IL-8). Alterations in neutrophils, lymphocytes and platelets accompany the systemic inflammatory response to cancer and infections. Neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio for example have been recognized as factors related to poor prognosis for many solid tumors, including bladder cancer, and their role has been found important even for the prognosis of SARS-CoV-2 infection. Key Messages: All these mechanisms should be further analyzed in order to find new therapeutic agents and new strategies to block infection and cancer progression. Further than commonly used therapies, controlling cytokine production and inflammatory response is a promising field.

ImportanceThere are gender differences in vulnerability to the Coronavirus disease 2019 (COVID-19), with men experiencing more severe disease at any age. The use of anti-androgen drugs, like 5-alpha reductase inhibitors (5ARIs), could protect from severe pulmonary disease.ObjectiveTo determine whether men who received 5ARIs for benign prostatic hyperplasia (BPH) have a lower risk of hospitalization for COVID-19.DesignThis is a case-control study on patients hospitalized for COVID-19 (cases), matched to beneficiaries of the Lombardy Regional Health Service (controls).SettingData were collected by two high-volume COVID-19 regional centres of Lombardy (Italy) from 1st March to 24th April 2020.ParticipantsConsecutive patients positive for SARS-CoV-2 virus according to the WHO guidance, who required hospitalization.ExposureBPH treatment with 5ARIs (finasteride/dutasteride) in the last six months.Main Outcome(s) and Measure(s)The primary outcome was to compare the prevalence of male patients chronically exposed to 5ARIs, who required hospitalization for COVID-19, with the one of age-matched males in Lombardy.ResultsOverall, 1,432 COVID-19 patients were included. Among the 943 males, 45 (4.77%) patients were exposed to chronic 5ARI therapy. COVID-19 patients aged >55 years under 5ARI treatment were significantly less than expected on the basis of the prevalence of 5ARI treatment among age-matched controls (5.57 vs. 8.14%; p=0.0083, 95%CI=0.75-3.97%). This disproportion was even higher for men aged >65 (7.14 vs. 12.31%; p=0.0001, 95%CI=2.83-6.97%).Eighteen 5ARIs-patients died; the mean age of men who died was higher than those who did not: 75.98±9.29 vs. 64.78±13.57 (pConclusions and RelevanceIn this case-control study the use of 5ARIs was less frequent among patients hospitalized for COVID-19 than among controls, suggesting that men exposed to 5ARIs might be less vulnerable to severe COVID-19. This observation further supports the idea to test in randomized clinical trials whether anti-androgen therapies can prevent the transition from paucisymptomatic SARS-CoV-2 infection to overt pulmonary disease.KEY POINTSQuestionMay treatment of benign prostatic hyperplasia with 5-alpha reductase inhibitors (5ARIs) impact on COVID-19-related hospitalization risk?FindingsIn this case-control study, which compared 943 adult males hospitalized for COVID-19 with age-matched men from Lombardy (all beneficiaries of the Regional Health Service), the proportion of patients aged >55 years, who were exposed to 5ARIs (dutasteride, finasteride), was significantly lower (5.57%) than that of the general male population (8.14%) (p=0.0083, 95%CI=0.75-3.97%).MeaningThe use of 5ARIs was associated with a potential reduced risk of hospitalization for COVID-19 in men older than >55 years. This suggests the opportunity to test whether anti-androgen therapies can prevent the transition from paucisymptomatic SARS-CoV-2 infection to overt pulmonary disease.

BACKGROUND: Basophils, eosinophils and monocytes may be involved in BCG-induced immune responses and be associated with outcomes of bladder cancer patients receiving intravesical BCG. Our objective was to explore the association of baseline counts of basophils, eosinophils and monocytes with outcomes of patients with high-grade T1 bladder cancer receiving a standard course of intravesical BCG. METHODS: We retrospectively reviewed medical records of patients with primary T1 HG/G3 bladder cancer. After re-TURBT, patients were treated with a 6-week course of intravesical BCG induction followed by intravesical BCG every week for 3 weeks given at 3, 6, 12, 18, 24, 30 and 36 months from initiation of therapy The analysis of potential risk factors for recurrence, muscle invasion and cancer-specific and overall survival was performed using univariable Cox regression models. Those factors that presented, at univariate analysis, an association with the event at a liberal p

Purpose To evaluate the predictive factors of pT0 at repeated transurethral resection of the bladder (re-TURB) in pT1 high-grade (HG) nonmuscle invasive bladder cancer in order to explore the possibility to avoid it in well-selected patients. Methods This multicenter retrospective study included patients with pT1HG nonmuscle invasive bladder cancer from 4 different centers who underwent a complete TURB. Re-TURB was defined as a second resection which involved the site of the first TURB performed within 2-6 weeks from the previous resection. A multivariable logistic-regression model was performed to evaluate the predictors of pT0 at re-TURB. A nomogram was built to calculate the probability of obtaining a negative histology at re-TURB. The performance of the nomogram and its net benefit were tested with the decision curve analysis. Results Overall, 321 patients were included in the study. On multivariable logistic regression, detrusor muscle in the specimen (HR 1.99, P = 0.02), concomitant carcinoma in situ (HR 0.29, P = 0.005) and resection performed with en-bloc technique (HR 7.71, P = 0.01) were independent predictors of pT0 at re-TURB. Decision curve analysis showed a net benefit for the nomogram for each probability over 0.35 compared to the strategy to perform a re-TURB in all pT1HG tumors. Conclusions The presence of detrusor muscle in TURB specimen, the absence of concomitant carcinoma in situ and the en-bloc resection were able to predict a negative histology at re-TURB, opening the door to the possibility to avoid it in an extremely well-selected cohort of patients. External validations and prospective studies are urgently needed.

The aim of this multicenter study was to investigate the prognostic role of neutrophil-to-lymphocyte ratio (NLR) and to validate the NLR cutoff of 3 in a large multi-institutional cohort of patients with primary T1 HG/G3 non-muscle-invasive bladder cancer (NMIBC)., M.D.V. is supported by the Scholarship Foundation of the Republic of Austria - OeAD and by the EUSP Scholarship - European Association of Urology.

Background It has been shown that active surveillance (AS) is feasible and effective in a subset of patients with recurrent low-grade (LG) non–muscle-invasive bladder cancer (NMIBC). Objective To update a previous preliminary series and investigate pathological outcomes for patients who failed to remain on AS. Design, setting, and participants Prospective observational cohort study started in February 2008, and currently still active, at a tertiary university hospital, including patients with pathologically confirmed NMIBC who experienced recurrence during follow-up. Intervention AS monitoring consisted of cytology and in-office flexible cystoscopy every 3 mo for the first year, and every 6 mo thereafter. Outcome measurements and statistical analysis The primary endpoint was pathological results for patients who failed to remain on AS. The secondary outcome was an update of clinical results from our previous series. Data were complemented by descriptive statistical analysis and univariable and multivariable proportional hazards Cox regression. Results and limitations Overall, 167 patients were included. Of 181 AS events, 61 (33.7%) were deemed to require treatment because of positive cytology (n = 10), gross haematuria (n = 11), and increases in the tumour number (n = 15), or size (n = 17), or both (n = 8). The median time on AS was 12 mo (interquartile range 4–26). Pathological specimens from AS failures did not show any malignancy in 20 cases. Histopathology identified urothelial hyperplasia and oedema, submucosal vascular ectasia, mucosal erosion, polypoid cystitis, von Brunn nest hyperplasia, and squamous metaplasia. The time from first transurethral resection to AS start was inversely associated with recurrence-free survival (hazard ratio 0.97, 95% confidence interval 0.96–1.00; p = 0.024). The study lacks statistical subanalyses focusing on patients with failure and negative neoplastic pathological outcomes. Conclusions AS might be a reasonable strategy in patients presenting with small LG pTa/pT1a recurrent bladder tumours. Approximately 30% of patients deemed to have AS failure did not harbour any neoplastic lesion, strengthening the role of AS. Patient summary Patients with small low-grade pTa/pT1a recurrent papillary bladder tumours could benefit from an active surveillance protocol with no significant risk of pathological progression to muscle-invasive cancer.

Context Repeat transurethral resection (reTUR) is advocated as a fundamental step towards complete clearance and appropriate staging of T1 bladder cancer tumors. Objective To assess the impact of reTUR in T1 bladder cancer via a systematic review of the literature and meta-analysis of available data sets. Evidence acquisition After definition of the population and of the outcome, a systematic search of English language articles in the literature from 1980 to 2016 was performed. The pooled prevalence of residual tumor and of upstaging at reTUR were assessed and computed using a random effects model to take into account heterogeneity showed by I 2 and Cochran's Q values. A sensitivity analysis was conducted to exclude excessive influence by a single study. Evidence synthesis Among the papers identified, 29 were selected. A total of 3566 and 2556 cases formed the study population for assessment of the prevalence of residual tumor and upstaging, respectively. The corresponding numbers for the subgroup with detrusor muscle involvement at the initial TUR were 1565 and 1187. The pooled prevalence was 0.56 (95% confidence interval [CI] 0.48–0.63) for residual tumor and 0.1 (95% CI 0.06–0.14) for upstaging to T2 at reTUR. The corresponding rates for the detrusor muscle subgroup were 0.47 (95% CI 0.33–0.62) and 0.1 (95% CI 0.06–0.14). The sensitivity analysis excluded an excessive influence of each of the studies examined. Conclusions Pooled prevalence rates for residual tumor (∼50%) and upstaging to invasive disease (10%) at reTUR in T1 cases were high, and were stable among studies in different decades and for cases with detrusor muscle involvement at the initial TUR. Therefore, reTUR remains a fundamental procedure. Patient summary Repeat transurethral resection after a diagnosis of stage T1 bladder cancer is recommended given the high risk of misallocation to the proper treatment.

Purpose: 68Ga labeled prostate specific membrane antigen positron emission tomography/computerized tomography may represent the most promising imaging modality to identify and risk stratify prostate cancer in patients with contraindications to or negative multiparametric magnetic resonance imaging.Materials and Methods: In this prospective observational study we analyzed 68Ga labeled prostate specific membrane antigen positron emission tomography/computerized tomography in a select group of patients with persistently elevated prostate specific antigen and/or Prostate Health Index suspicious for prostate cancer, negative digital rectal examination and at least 1 negative biopsy. The cohort comprised men with equivocal multiparametric magnetic resonance imaging (Prostate Imaging-Reporting and Data System, version 2 score of 2 or less), or an absolute or relative contraindication to multiparametric magnetic resonance imaging. Sensitivity, specificity and CIs were calculated compared to histopathology finding...

Introduction Magnetic Resonance Imaging (MRI) has emerged as the most accurate diagnostic tool, showing a high sensitivity in the diagnosis of clinically significant prostate cancer (csCaP). However only a minority of patients with a PI-RADS 3 lesion at multiparametric magnetic resonance imaging (MRI) are diagnosed with csCaP. The aim of the current study was to assess whether high resolution micro-ultrasound (microUS) could help in sub-stratifying the risk of csCaP in this specific population. Material and methods We retrospectively analyzed the records of 111 consecutive patients scheduled for a prostate biopsy with at least 1 PI-RADS 3 lesions at MRI. We excluded patients with a PIRADS >3 lesion, even if they had a coexisting PIRADS 3 lesions. MicroUS was performed in all patients before prostate biopsy by an operator blind to MRI results. The Prostate Risk Identification using MicroUS (PRI-MUS) protocol was used to assess the risk of CaP and csCaP. All patients received both targeted and systematic biopsies. The primary endpoint was to determine the diagnostic accuracy of microUS in detection of csCaP in patients with a PI-RADS 3 lesion at MRI. Specifically, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of microUS were determined. Multivariable logistic regression models (MLRMs) were fitted to identify predictors of CaP. The diagnostic accuracy was reported as area under the receiver operator characteristic (ROC) curve. Results Overall, 43 patients (38.7%) harboured CaP and 22 (20%) csCaP. MicroUS showed a high sensitivity and negative predictive value (100%), while its specificity and positive predictive value were 33.7% and 27.2%, respectively. Among patients without lesions at microUS, 25 (83.3%) did not harbour CaP, while 5 (16.7%) patients were diagnosed with a Gleason score 6 CaP, with no patients harbouring csCaP. Using microUS, the csCaP detection would have remained 100%, while reducing the detection of insignificant CaP of a 23.8% extent (n = 5). In MLRMs, lesion identified at microUS and continuously-coded PSAd were independent predictors of CaP. The accuracy of a model including PRI-MUS score, digital rectal examination (DRE), PSA density, age and family history was 0.744 (95% CI: 0.645 – 0.843). Conclusion In our single-institutional retrospective study, microUS was potentially capable to stratify the presence of CaP in patients with an equivocal MRI. Further prospective studies on larger populations are needed to validate our results.

Context En-bloc resection of bladder tumors (ERBT) is a promising alternative to conventional transurethral resection of bladder tumor. Objective To review the current results of ERBT. Evidence acquisition A literature search of articles that included the keywords bladder and en bloc was performed on July 15, 2016 using PubMed/Medline. Relevant English-written original articles were considered. Data from the manuscripts were categorized focusing on recent trends on resection techniques, specimens' quality, morbidity, and recurrence. Evidence synthesis ERBT provides high rates of detrusor muscle (> 95%) and specimens of high quality for pathological evaluation. It has not been analyzed whether second resections can therefore be avoided. All energy devices (lasers, electric cautery) have been used to perform ERBT with similar perioperative and oncological results. Data show that there is not much difference in respect of perioperative morbidity compared with conventional transurethral resection of bladder tumor; however, only a few publications used a systematic classification system. No conclusions can be drawn regarding the impact of ERBT on recurrence. Conclusions The major advantage of ERBT is the high rate of detrusor muscle. Based on limited data, no significant differences are observed regarding perioperative morbidity and recurrence rates. Patient summary En-bloc resection of bladder tumor is an emerging technique aimed at improving quality of surgical specimens. Available evidences suggest safety and oncologic equivalence compared with the standard transurethral resection of bladder tumor.

Although chemotherapeutic agents have been used for decades, the mechanisms of action, mechanisms of resistance, and the best treatment schedule remain elusive. Mitomycin C (MMC) is the gold standard treatment for non-muscle-invasive bladder cancer (NMIBC). However, it is effective only in a subset of patients, suggesting that, aside from cytotoxicity, other mechanisms could be involved in mediating the success of the treatment. Here, we showed that MMC promotes immunogenic cell death (ICD) and in vivo tumor protection. MMC-induced ICD relied on metabolic reprogramming of tumor cells toward increased oxidative phosphorylation. This favored increased mitochondrial permeability leading to the cytoplasmic release of mitochondrial DNA, which activated the inflammasome for efficient IL-1β (interleukin-1β) secretion that promoted dendritic cell maturation. Resistance to ICD was associated with mitochondrial dysfunction related to low abundance of complex I of the respiratory chain. Analysis of complex I in patient tumors indicated that low abundance of this mitochondrial complex was associated with recurrence incidence after chemotherapy in patients with NMIBC. The identification of mitochondria-mediated ICD as a mechanism of action of MMC offers opportunities to optimize bladder cancer management and provides potential markers of treatment efficacy that could be used for patient stratification.

Positron emission tomography (PET)/computed tomography (CT) withTo test the diagnostic performance ofFrom January 2017 to December 2018 we prospectively enrolled 97 patients with persistently elevated prostate-specific antigen and/or Prostate Health Index score, negative digital rectal examination, and previous negative biopsy. We also included patients with either negative mpMRI or contraindications to or positive mpMRI but previous negative biopsy.Patients underwent 68Ga-PSMA PET/CT with additional pelvic reconstruction.The primary endpoint of the study was the diagnostic performance ofIn our cohort of patients with high suspicion of cancer,Positron emission tomography/computed tomography with a

Objectives: The aim of this multicenter study was to investigate the prognostic role of type 2 diabetes mellitus (T2DM) comorbidity in a large multi-institutional cohort of patients with primary T1HG/G3 non–muscle-invasive bladder cancer (NMIBC) treated with transurethral resection of the bladder (TURB). Materials and methods: A total of 1,172 patients with primary T1 HG/G3 who had NMIBC on re-TURB and who received adjuvant intravesical bacillus Calmette-Guérin therapy with maintenance were included. Endpoints were recurrence-free survival and progression-free survival. Results: A total of 231 (19.7%) of patients had T2DM prior to TURB. Five-year recurrence-free survival estimates were 12.5% in patients with T2DM compared to 36% in patients without T2DM, P < 0.0001. Five-year PFS estimates were 60.5% in patients with T2DM compared to 70.2% in patients without T2DM, P = 0.003. T2DM was independently associated with disease recurrence (hazard ratio = 1.41; 95% confidence interval = 1.20–1.66, P < 0.001) and progression (hazard ratio = 1.27; 95% confidence interval = 0.99–1.63, P < 0.001), after adjusting for other known predictive factors such as tumor size, multifocality, T1G3 on re-TURB, body mass index, lymphovascular invasion, and neutrophil-to-lymphocytes ratio. Conclusions: Given the potential implications for management, prospective validation of this finding along with translational studies designed to investigate the underlying biology of such an association are warranted.

Background The aim of this study was to identify the predictive factors for progression defined as any event that shifted the management of the disease from a bladder sparing approach, by comparing patients with pure versus non-pure carcinoma in situ (CIS) of the bladder. Methods A retrospective analysis was carried out in consecutive patients affected by newly-diagnosed pure CIS and non-pure CIS (excluding cases with concomitant muscle invasive cancer). All patients were enrolled a in our institution from 1998 to 2010. Data was prospectively collected. Main end point was progression-free survival. Results Overall, 149 patients with CIS were identified for the analysis. A total of 98 patients had pure CIS (66%). Median follow-up was 103 months (range: 40-206 months). Progression occurred in 29 patients (19%). A total of 30 patients died during the follow-up (20%). In 13 cases (9%), the death was cancer specific. Progression-free survival estimate was 181 months (95% CI: 169-193 months) and 154 months (95% CI: 133-176 months) respectively for pure and non-pure CIS population (P=0.03). Among examined variables (age, gender, symptoms, smoking habit, ASA score, number of bacillus Calmette-Guerin [BCG] instillations), multivariate analysis disclosed that only CIS type was an independent predictor of progression (P=0.03) with a relative risk of 0.37 in favor of pure CIS. Conclusions Pure and non-pure CIS are efficiently treated by BCG therapy combined with trans-urethral resection and/or radical cystectomy, with relatively low rate of progression. CIS type was the only significant predictor of progression.

To investigate the clinical performance of a new mRNA-based urine test, aiming to avoid unnecessary follow-up cystoscopy in patients under active surveillance (AS) for recurrent NMIBC. This is a prospective cohort study enrolling patients with history of low-grade (LG) NMIBC, who developed a recurrence during the follow-up and underwent AS. Their urinary samples were analyzed by Xpert BC Monitor (Cepheid, Sunnyvale, CA, USA). The primary endpoint was to investigate if Xpert BC Monitor could avoid unnecessary cystoscopy during the follow-up period. Its sensitivity, specificity, PPVs and NPVs were calculated. A cutoff of 0.4 “linear discriminant analysis” (LDA) was optimized for the AS setting. The cohort consisted of 106 patients with a mean age of 72 ± 9.52 and a median follow-up from AS start of 8.8 (range 0–56.5) months. No statistically significant difference was found for the mean age, smoker status, lesion size, and number of lesions with a cutoff of 0.4. Of 106 patients, 22 (20.8%) were deemed to require treatment because of cystoscopic changes in size and/or number of lesions during the follow-up period. Using a cutoff value of

BACKGROUND There is an unmet clinical need for more biochemical specific tests that may detect clinically significant recurrent PCa at an early stage after radical prostatectomy (RP). Our purpose is to test the hypothesis that p2PSA (Index test) detects prostate cancer relapse (BCR) earlier than the current Reference Standard Test (total prostate-specific antigen [tPSA]) in patients who underwent RP for localized PCa. METHODS This is an observational, prospective, cohort, follow-up study in patients subjected to RALP (robotic assisted laparoscopic radical prostatectomy) for clinically localized PCa from January 2013 to July 2013 at a high-volume Institution (450 average RP/year). A blood sample, for tPSA and p2PSA, was prospectively drawn after 3, 6, and 12 months and then every 6 months during the following two years. The primary outcome is to determine whether or not kinetics in rising of p2PSA significantly anticipates the tPSA kinetics. Exploratory data analysis was used to identify relationship between different variables. RESULTS Over 134 patients 20 BCRs were detected according to tPSA cut-off. Five patients showed a contemporary increase of tPSA and p2PSA, 11 presented a p2PSA increase earlier than tPSA increase (13.9 months ±9.7). In four patients, the increase of PSA was not associated with a p2PSA>0.8 pg/mL. The correlation between tPSA and p2PSA according to Sperman's rho coefficient was statistically significant at 3, 6, 18 and 30 months: 0.416 (P

INTRODUCTION AND OBJECTIVES:Oncofid-P-B (Fidia Farmaceutici) is a novel water-soluble muco-adhesive conjugate of paclitaxel-hyaluronic acid (P-HA. Very favorable safety and efficacy after 6 weeks in BCG unresponsive CIS patients and after 6 weeks followed by 6+6 months in Ta G1-G2 patients was previously reported. The excellent safety profile prompted the design of this trial to assess safety, tolerability and efficacy of P-HA administered for 12 consecutive weeks, followed by 12 monthly instillations, in BCG unresponsive/intolerant CIS patients.METHODS:This is an open-label, single arm, multicenter study to assess safety, tolerability and efficacy of P-HA administered in 20 patients with CIS, who are unresponsive or intolerant to BCG and unwilling or unfit for cystectomy. P-HA was administered weekly by intravesical instillation for 12 consecutive weeks (intensive phase), followed, in responsive patients, by 12 monthly instillations (maintenance). The primary end-point is the overall safety profile. Seco...
