Oncological and safety profiles in patients undergoing simultaneous transurethral resection (TUR) of bladder tumour and TUR of the prostate.

OBJECTIVES: To determine the oncological impact and adverse events of performing simultaneous transurethral resection of bladder tumour (TURB) and transurethral resection of the prostate (TURP), as evidence on the outcomes of simultaneous TURB for bladder cancer and TURP for obstructive benign prostatic hyperplasia is limited and contradictory. PATIENTS AND METHODS: Patients from 12 European hospitals treated with either TURB alone or simultaneous TURB and TURP (TURB+TURP) were retrospectively analysed. A propensity score matching (PSM) 1:1 was performed with patients from the TURB+TURP group matched to TURB-alone patients. Associations between surgery approach with recurrence-free (RFS) and progression-free (PFS) survivals were assessed in Cox regression models before and after PSM. We performed a subgroup analysis in patients with risk factors for recurrence (multifocality and/or tumour size >3 cm). RESULTS: A total of 762 men were included, among whom, 76% (581) underwent a TURB alone and 24% (181) a TURB+TURP. There was no difference in terms of tumour characteristics between the groups. We observed comparable length of stay as well as complication rates including major complications (Clavien-Dindo Grade ≥III) for the TURB-alone vs TURB+TURP groups, while the latest led to longer operative time (P < 0.001). During a median follow-up of 44 months, there were more recurrences in the TURB-alone (47%) compared to the TURB+TURP group (28%; P < 0.001). Interestingly, there were more recurrences at the bladder neck/prostatic fossa in the TURB-alone group (55% vs 3%, P < 0.001). TURB+TURP procedures were associated with improved RFS (hazard ratio [HR] 0.39, 95% confidence interval [CI] 0.29-0.53; P < 0.001), but not PFS (HR 1.63, 95% CI 0.90-2.98; P = 0.11). Within the PSM cohort of 254 patients, the simultaneous TURB+TURP was still associated with improved RFS (HR 0.33, 95% CI 0.22-0.49; P < 0.001). This was also true in the subgroup of 380 patients with recurrence risk factors (HR 0.41, 95% CI 0.28-0.62; P < 0.001). CONCLUSION: In our contemporary cohort, simultaneous TURB and TURP seems to be an oncologically safe option that may, even, improve RFS by potentially preventing disease recurrence at the bladder neck and in the prostatic fossa.

Online Crowdfunding for Urologic Cancer Care.

Background: we aimed to characterize the financial needs expressed through online crowdfunding for urologic cancers. Methods: the data used in this study came from the online crowdfunding platform GoFundMe.com. Using an automated software method, we extracted data for campaigns related to urologic cancers. Subsequently, four independent investigators reviewed all extracted data on prostate, bladder, kidney and testicular cancer. We analyzed campaigns' basic characteristics, goals, fundraising, type of treatment and factors associated with successful campaigns. Results: in total, we identified 2126 individual campaigns, which were related to direct treatment costs (34%), living expenses (17%) or both (48%). Median fundraising amounts were greatest for testicular cancer. Campaigns for both complementary and alternative medicine (CAM) (median $11,000) or CAM alone (median $8527) achieved higher fundraising totals compared with those for conventional treatments alone (median $5362) (p < 0.01). The number of social media shares was independently associated with campaign success and highest quartile of fundraising. Conclusions: using an automated web-based approach, we identified and characterized online crowdfunding for urologic cancer care. These findings indicated a diverse range of patient needs related to urologic care and factors related to campaigns' success.

Carboplatin-based adjuvant chemotherapy versus observation after radical cystectomy in patients with pN1-3 urothelial bladder cancer.

PURPOSE: To test the impact of carboplatin-based ACT on overall survival (OS) in patients with pN1-3 cM0 BCa. METHODS: A retrospective analysis was conducted on 1057 patients with pTany pN1-3 cM0 urothelial BCa treated with or without carboplatin-based ACT after radical cystectomy and bilateral lymph-node dissection between 2002 and 2018 at 12 European and North-American hospitals. No patient received neoadjuvant chemotherapy or radiation therapy. Only patients with negative surgical margins at surgery were included. A 3:1 propensity score matching (PSM) was performed using logistic regression to adjust for baseline characteristics. Univariable and multivariable Cox regression analyses were used to predict the effect of carboplatin-based ACT on OS. The Kaplan-Meier method was used to display OS in the matched cohort. RESULTS: Of the 1057 patients included in the study, 69 (6.5%) received carboplatin-based ACT. After PSM, 244 total patients were identified in two cohorts that did not differ for baseline characteristics. Death was recorded in 114 (46.7%) patients over a median follow-up of 19 months. In the multivariable Cox regression analyses, increasing age at surgery (hazard ratio [HR] 1.02, 95% confidence interval [CI] 1.01-1.06, p < 0.001) and increasing number of positive lymph nodes (HR 1.06, 95% CI 1.01-1.07, p = 0.02) were independent predictors of worse OS. The delivery of carboplatin-based ACT was not predictive of improved OS (HR 0.67, 95% CI 0.43-1.04, p = 0.08). The main limitations of this study are its retrospective design and the relatively low number of patients involved. CONCLUSIONS: Carboplatin-based might not improve OS in patients with pN1-3 cM0 BCa. Our results underline the need for alternative therapies for cisplatin-ineligible patients.

Impact of tumor size on the oncological outcome of high-grade nonmuscle invasive bladder cancer - examining the utility of classifying Ta bladder cancer based on size.

PURPOSE: To examine survival rates and to calculate the risk of disease recurrence, progression, overall, and cancer-specific mortality in patients diagnosed with high-risk NMIBC using a multi-institutional dataset to evaluate differences between the guidelines of the European Association of Urology and the guidelines of the National Comprehensive Cancer Network (NCCN) with regard to tumor size in risk stratification. METHODS AND MATERIAL: In total 1,116 individuals diagnosed with high-risk NMIBC between 2001 and 2013 were included in the analysis. Patients were stratified to NCCN guideline recommendations (high-grade T1, high-grade Ta ≤ 3 cm, and high-grade Ta > 3 cm). Recurrence and progression rates were calculated. Kaplan-Meier curves were fitted to examine differences in recurrence-free (RFS) and progression-free survival (PFS). Multivariable Cox proportional hazards regression models were employed to calculate differences in the RFS, PFS, overall, and cancer-specific survival (CSS). RESULTS: The majority of patients were diagnosed with high-grade T1 disease (N = 576, 51.6%), while 34.2% and 14.2% of patients were diagnosed with high-grade Ta ≤ 3 cm and Ta > 3 cm NMIBC, respectively. The 1- and 5-year RFS (1-year: 80.5% vs. 64.9%; 5-year: 58.6% vs. 48.3%, P = 0.048) and PFS (1-year: 99.1% vs. 98.6%; 5-year: 97.7% vs. 92.4%, P = 0.054) rates were higher in patients with Ta ≤ 3 cm. Patients diagnosed with high-grade Ta > 3 cm experienced unfavorable progression-free, and cancer-specific survival compared to high-grade Ta ≤ 3 cm, respectively (PFS: 2.41, 95% confidence interval [CI] 1.05-5.56, P = 0.038; CSS: hazard ratios [HR] 2.22, 95% CI 1.02-4.89, P = 0.048). CONCLUSION: Patients diagnosed with high-grade Ta NMIBC ≤3 cm demonstrated a favorable progression-free, and cancer-specific survival compared to patients diagnosed with high-grade Ta > 3 cm and high-grade T1 NMIBC.

A systematic review of preventive and therapeutic options for symptoms of cystitis in patients with bladder cancer receiving intravesical bacillus Calmette-Guérin immunotherapy.

Local adverse effects are the most common clinical issues in patients with bladder cancer receiving intravesical BCG immunotherapy. The aim of this systematic review was to present available options for prevention and treatment of cystitis symptoms related to bacillus Calmette-Guérin (BCG) intravesical instillations. A literature search within the Medline database was conducted in June 2018 with the following search terms: adverse events, Bacillus Calmette-Guerin, BCG, bladder cancer, cystitis, dose, dwell time, dysuria, frequency, intravesical instillations, haematuria, pain, side effects, toxicity and urgency. Eighteen relevant original articles were identified, including 15 randomized controlled trials. Potentially effective options to prevent symptoms of cystitis are BCG dose reduction, intravesical hyaluronic acid instillations and oral prulifloxacin or ofloxacin administration. For the treatment of BCG-related cystitis, available options include oral pentosan polysulphate or a combination of intravesical hyaluronic acid and chondroitin sulphate. The included studies were characterized by high heterogeneity in terms of BCG strains, schedules and endpoints. Studies on treatment of BCG-related cystitis included only small number of patients. Studies on directed medical interventions did not consider the influence on the BCG efficacy. Among few proposed preventive or therapeutic options for symptoms of cystitis related to BCG, none was proven to be both definitively effective and oncologically safe.

Assessment of Pain Management, Acceptance of Illness, and Adjustment to Life with Cancer in Patients with Nonmuscle Invasive Bladder Cancer.

PURPOSE: According to the European Association of Urology bladder cancer is the seventh most commonly diagnosed malignancy in the world's male population. Despite its high incidence, papers evaluating psychological state in those patients' group are lacking. The purpose of the study was to evaluate pain management, disease acceptance, and adjustment to cancer in homogenous group of patients diagnosed with nonmuscle-invasive bladder cancer (NMIBC). METHODS: Group of 252 male patients who were scheduled for NMIBC treatment were prospectively evaluated. Patients fulfilled Acceptance of Illness Scale (AIS), Mini-Mental Adjustment to Cancer (Mini-MAC) and Coping Strategies (CSQ) questionnaires before treatment introduction. RESULTS: Highest CSQ score was achieved by the coping self-statements subscale (mean=18,37). The catastrophizing subscale score was the lowest (mean=11,24). Place of residence affected results of CSQ statement about pain control. Catastrophizing and coping self-statements strategies were associated with matrimonial status. In the Mini-MAC questionnaire the fighting spirit way of coping had the highest (21,73) and the helplessness-hopelessness subscale had the lowest mean value (13,3). Matrimonial status was strongly associated with anxious preoccupation, fighting spirit, and helplessness - hopelessness way of coping. The mean AIS test score was 28.8. AIS result was influenced by patient's marital status, yet not by education, place of residence, nor any clinical factor. CONCLUSIONS: In the examined group, the level of acceptance of the disease reached values that were slightly higher than the average. It indicated a fairly good adaptation to cancer. Among the methods of coping with cancer, the constructive style is definitely dominant with a high intensity of the fighting spirit strategy. The destructive style of cancer coping reached low values with a low intensity of helplessness/hopelessness strategy. From pain coping strategies, self-statements and praying/hoping were the most commonly chosen ways, whereas catastrophizing was the rarest. Many associations between various questioners' results were also observed.

Urinary diversion metabolic complications - underestimated problem.

Bladder cancer is one of the most frequent human cancers. In 2011 more than six thousand people in Poland developed BC and more than three thousand died because of it. Treatment of bladder cancer depends on its stage. In less advanced tumours (Ta, Tcis, T1) transurethral resection of bladder tumor with adjuvant immunotherapy is often therapeutic. In more advanced cases (≥ T2) radical cystectomy is needed. There are several surgical types of post-cystectomy urinary diversion divided into two fundamental types - enabling and not enabling urine continence. The most common procedures include ureterocutaneostomy, ileal or colon conduit, orthopic ileal bladder, heterotopic continent bladder replacement (pouch) and urinary diversion via the rectum. Depending on type of cystectomy, various metabolic complications occur, because the absorptive-secretory function of used bowel segment is intact. Complications include bowel dysfunction, malabsorption of various vitamins, acid-base imbalance, electrolyte imbalance, abnormalities in bone metabolism, formation of renal calculi, secondary malignancies and disturbances in function of kidneys or liver. Early diagnosed complications can be treated easier, recognised in advanced stages are often irreversible. In our paper we present review of different approaches to bladder cancer treatment and metabolic complications occurring after these procedures.

Simple method for determining human serum 2,2-diphenyl-1-picryl-hydrazyl (DPPH) radical scavenging activity - possible application in clinical studies on dietary antioxidants.

BACKGROUND: 2,2-Diphenyl-1-picryl-hydrazyl (DPPH) radical decomposition in alcohol solution is widely used, characterizing plant antioxidants that can rise in serum after fruit and vegetable intake. However, this test failed reproducible results with serum due to protein precipitation. We describe the application of serum deproteinization with acetonitrile relating to the DPPH test. METHODS: Assay sensitivity, linearity, repeatability and storage effect were determined in serum samples deproteinized with an equal volume of acetonitrile. Associations between the DPPH test and the ferric reducing ability of serum (FRAP) method, measuring total antioxidant potential, were evaluated in sera from 78 healthy non-smoking men. The effect of a single ingestion of 1 L of cloudy apple juice on the serum DPPH radical scavenging activity in healthy volunteers was also investigated. RESULTS: Assay linearity was within 5-25 microL (r=0.99, p<0.01). With 25 microL-deproteinized serum, coefficient of variation was 4.2% and detection limit was 0.5% of the initial amount of decomposed DPPH radical over 30 min incubation. There was no sera activity decrease over 14 days storage at -20 degrees C. Mean values of DPPH radical scavenging activity and FRAP obtained in human serum were 11.2+/-3.3% and 382.0+/-88.1 micromol/L, respectively. A positive significant linear correlation was observed between these two methods (r=0.42, p<0.01). Serum supplementation with 50 micromol/L of catechin, gallic acid, ascorbic acid or uric acid enhanced DPPH test results. One brisk serving of 1 L of apple juice caused a significant increment of serum DPPH radical scavenging activity (1.9+/-1.9%, p<0.01) in 12 healthy subjects 1 h after juice ingestion. CONCLUSIONS: Applicability of the DPPH test to deproteinized serum with acetonitrile revealed numerous advantages, validating its practicability, simplicity and cost effectiveness as a tool in the estimation of antioxidant status in humans.
