Consistencies in Follow-up After Radical Cystectomy for Bladder Cancer: A Framework Based on Expert Practices Collaboratively Developed by the European Association of Urology Bladder Cancer Guideline Panels.

BACKGROUND AND OBJECTIVE: There is no standardized regimen for follow-up after radical cystectomy (RC) for bladder cancer (BC). To address this gap, we conducted a multicenter study involving urologist members from the European Association of Urology (EAU) bladder cancer guideline panels. Our objective was to identify consistent post-RC follow-up strategies and develop a practice-based framework based on expert opinion. METHODS: We surveyed 27 urologist members of the EAU guideline panels for non-muscle-invasive bladder cancer and muscle-invasive and metastatic bladder cancer using a pre-tested questionnaire with dichotomous responses. The survey inquired about follow-up strategies after RC and the use of risk-adapted strategies. Consistency was defined as >75% affirmative responses for follow-up practices commencing 3 mo after RC. Descriptive statistics were used for analysis. KEY FINDINGS AND LIMITATIONS: We received responses from 96% of the panel members, who provided data from 21 European hospitals. Risk-adapted follow-up is used in 53% of hospitals, with uniform criteria for high-risk (at least ≥pT3 or pN+) and low-risk ([y]pT0/a/1N0) cases. In the absence of agreement for risk-based follow up, a non-risk-adapted framework for follow-up was developed. Higher conformity was observed within the initial 3 yr, followed by a decline in subsequent follow-up. Follow-up was most frequent during the first year, including patient assessments, physical examinations, and laboratory tests. Computed tomography of the chest and abdomen/pelvis was the most common imaging modality, initially at least biannually, and then annually from years 2 to 5. There was a lack of consistency for continuing follow-up beyond 10 yr after RC. CONCLUSIONS AND CLINICAL IMPLICATIONS: This practice-based post-RC follow-up framework developed by EAU bladder cancer experts may serve as a valuable guide for urologists in the absence of prospective randomized studies. PATIENT SUMMARY: We asked urologists from the EAU bladder cancer guideline panels about their patient follow-up after surgical removal of the bladder for bladder cancer. We found that although urologists have varying approaches, there are also common follow-up practices across the panel. We created a practical follow-up framework that could be useful for urologists in their day-to-day practice.

The Safety, Tolerability, and Preliminary Efficacy of a Gemcitabine-releasing Intravesical System (TAR-200) in American Urological Association-defined Intermediate-risk Non-muscle-invasive Bladder Cancer Patients: A Phase 1b Study.

Background and objective: Patients with intermediate-risk non-muscle-invasive bladder cancer (IR NMIBC) have a high risk of recurrence and need effective therapies to reduce the risk of disease recurrence or progression. This phase 1b study (NCT02720367) assessed the safety and tolerability of TAR-200, an intravesical drug delivery system, in participants with IR NMIBC. Methods: Participants with recurrent IR NMIBC were eligible. Participants received either two 7-d or two 21-d TAR-200 dosing cycles over a 4-6-wk period in a marker lesion/ablation design. TAR-200 was placed in the window between the cystoscopy showing recurrent papillary disease and the subsequent complete transurethral resection of the bladder tumour. The primary endpoint was TAR-200 safety. The secondary endpoints included TAR-200 tolerability, pharmacokinetics, and preliminary efficacy. Key findings and limitations: Twelve participants received TAR-200 treatment. No TAR-200-related serious or grade ≥ 3 treatment-emergent adverse events (TEAEs) occurred. Nine participants had grade ≤ 2 TAR-200-related TEAEs, with urgency, dysuria, and haematuria being most common. Two participants refused a second dosing cycle due to urinary urgency and frequency. Insertion and removal of TAR-200 was successful in all cases. Plasma gemcitabine concentrations remained below the lower limit of detection. Five participants (42%) had complete response (CR): four had pathological CR and one had CR based on visual assessment. Conclusions and clinical implications: TAR-200 appears to be safe and well tolerated, with encouraging preliminary efficacy in participants with IR NMIBC. This study lays the groundwork for the multiple phase 2 and 3 global studies that are currently on-going for TAR-200. Patient summary: In this study, researchers evaluated the safety of the novel drug delivery system TAR-200 in participants with intermediate-risk non-muscle-invasive bladder cancer. They concluded that TAR-200 was safe and well tolerated with promising antitumour activity.

European Association of Urology Guidelines on Muscle-invasive and Metastatic Bladder Cancer: Summary of the 2023 Guidelines.

CONTEXT: We present an overview of the updated 2023 European Association of Urology (EAU) guidelines for muscle-invasive and metastatic bladder cancer (MMIBC). OBJECTIVE: To provide practical evidence-based recommendations and consensus statements on the clinical management of MMIBC with a focus on diagnosis and treatment. EVIDENCE ACQUISITION: A broad and comprehensive scoping exercise covering all areas of the MMIBC guidelines has been performed annually since 2017. Searches cover the Medline, EMBASE, and Cochrane Libraries databases for yearly guideline updates. A level of evidence and strength of recommendation are assigned. The evidence cutoff date for the 2023 MIBC guidelines was May 4, 2022. EVIDENCE SYNTHESIS: Patients should be counselled regarding risk factors for bladder cancer. Pathologists should describe tumour and lymph nodes in detail, including the presence of histological subtypes. The importance of the presence or absence of urothelial carcinoma (UC) in the prostatic urethra is emphasised. Magnetic resonance imaging (MRI) of the bladder is superior to computed tomography (CT) for disease staging, specifically in differentiating T1 from T2 disease, and may lead to a change in treatment approach in patients at high risk of an invasive tumour. Imaging of the upper urinary tract, lymph nodes, and distant metastasis is performed with CT or MRI; the additional value of flurodeoxyglucose positron emission tomography/CT still needs to be determined. Frail and comorbid patients should be evaluated by a multidisciplinary team. Postoperative histology remains the most important prognostic variable, while circulating tumour DNA appears to be an interesting predictive marker. Neoadjuvant systemic therapy remains cisplatin-based. In motivated and selected women and men, sexual organ-preserving cystectomy results in better functional outcomes without compromising oncological outcomes. Robotic and open cystectomy have comparable outcomes and should be combined with (extended) lymph node dissection. The diversion type is an individual choice after taking patient and tumour characteristics into account. Radical cystectomy remains a highly complex procedure with considerable morbidity and risk of mortality, although lower rates are observed for higher hospital volumes (>20 cases/yr). With proper patient selection, trimodal therapy (chemoradiation) has comparable outcomes to radical cystectomy. Adjuvant chemotherapy after surgery improves disease-specific survival and overall survival (OS) in patients with high-risk disease who did not receive neoadjuvant treatment, and is strongly recommended. There is a weak recommendation for adjuvant nivolumab, as OS data are not yet available. Health-related quality of life should be assessed using validated questionnaires at baseline and after treatment. Surveillance is needed to monitor for recurrent cancer and functional outcomes. Recurrences detected on follow-up seem to have better prognosis than symptomatic recurrences. CONCLUSIONS: This summary of the 2023 EAU guidelines provides updated information on the diagnosis and treatment of MMIBC for incorporation into clinical practice. PATIENT SUMMARY: The European Association of Urology guidelines panel on muscle-invasive and metastatic bladder cancer has released an updated version of the guideline containing information on diagnosis and treatment of this disease. Recommendations are based on studies published up to May 4, 2022. Surgical removal of the bladder and bladder preservation are discussed, as well as updates on the use of chemotherapy and immunotherapy in localised and metastatic disease.

Chemoradiation for muscle-invasive bladder cancer using 5-fluorouracil versus capecitabine: A nationwide cohort study.

BACKGROUND AND PURPOSE: Oral capecitabine and intravenous 5-fluorouracil (5-FU) are both used as a radiosensitizer in chemoradiotherapy (CRT). A capecitabine-based regimen is more convenient for both patients and healthcare professionals. Since large comparative studies are lacking, we compared toxicity, overall survival (OS) and disease-free survival (DFS) between both CRT-regimens in patients with muscle-invasive bladder cancer (MIBC). MATERIALS AND METHODS: All patients diagnosed with non-metastatic MIBC between November 2017-November 2019 were consecutively included in the BlaZIB study. Data on patient, tumor, treatment characteristics and toxicity were prospectively collected from the medical files. From this cohort, all patients with cT2-4aN0-2/xM0/x, treated with capecitabine or 5-FU-based CRT were included in the current study. Toxicity in both groups was compared using Fisher-exact tests. Propensity score-based inverse probability treatment weighting (IPTW) was applied to correct for baseline differences between groups. IPTW-adjusted Kaplan-Meier OS and DFS curves were compared using log-rank tests. RESULTS: Of the 222 included patients, 111 (50%) were treated with 5-FU and 111 (50%) with capecitabine. Curative CRT was completed according to treatment plan in 77% of patients in the capecitabine-based group and 62% of the 5-FU group (p = 0.06). Adverse events (14 vs 21%, p = 0.29), 2-year OS (73% vs 61%, p = 0.07) and 2-year DFS (56% vs 50%, p = 0.50) did not differ significantly between groups. CONCLUSIONS: Chemoradiotherapy with capecitabine and MMC is associated with a similar toxicity profile compared to 5-FU plus MMC and no difference in survival was found. Capecitabine-based CRT, as a more patient-friendly schedule, may be considered as an alternative to a 5-FU-based regimen.

Positron Emission Tomography/Computed Tomography for Staging of Bladder Cancer: A Continuing Clinical Controversy.

Fluorodeoxyglucose-based positron emission tomography/computed tomography is increasingly being used for staging of muscle-invasive bladder cancer before treatment. However, international clinical guidelines are hesitant to recommend this approach, as conclusive scientific evidence on its usefulness is lacking. The question is whether and how this evidence can be obtained.

Circulating tumour cells to drive the use of neoadjuvant chemotherapy in patients with muscle-invasive bladder cancer.

BACKGROUND: Guidelines recommend neoadjuvant chemotherapy (NAC) for the treatment of nonmetastatic muscle-invasive bladder cancer (MIBC). NAC is, however, underutilized in practice because of its associated limited overall survival (OS) benefit and significant treatment-related toxicity. We hypothesized that the absence of circulating tumour cells (CTCs) identifies MIBC patients with such a favourable prognosis that NAC may be withheld. PATIENTS AND METHODS: The CirGuidance study was an open-label, multicentre trial that included patients with clinical stage T2-T4aN0-N1M0 MIBC, scheduled for radical cystectomy. CTC-negative patients (no CTCs detectable using the CELLSEARCH system) underwent radical surgery without NAC; CTC-positive patients (≥1 detectable CTCs) were advised to receive NAC, followed by radical surgery. The primary endpoint was the 2-year OS in the CTC-negative group with a prespecified criterion for trial success of ≥75% (95% confidence interval (CI) ±5%). RESULTS: A total of 273 patients were enrolled. Median age was 69 years; median follow-up was 36 months. The primary endpoint of 2-year OS in the CTC-negative group was 69.5% (N = 203; 95% CI 62.6%-75.5%). Two-year OS was 58.2% in the CTC-positive group (N = 70; 95% CI 45.5%-68.9%). CTC-positive patients had a higher rate of cancer-related mortality [hazard ratio (HR) 1.61, 95% CI 1.05-2.45, P = 0.03] and disease relapse (HR 1.87, 95% CI 1.28-2.73, P = 0.001) than CTC-negative patients. Explorative analyses suggested that CTC-positive patients who had received NAC (n = 22) survived longer than CTC-positive patients who had not (n = 48). CONCLUSION: The absence of CTCs in MIBC patients was associated with improved cancer-related mortality and a lower risk of disease relapse after cystectomy; however, their absence alone does not justify to withhold NAC. Exploratory analyses suggested that CTC-positive MIBC patients might derive more benefit from NAC. TRIAL REGISTRATION: Netherlands Trial Register NL3954; https://www.trialregister.nl/trial/3954.

International Bladder Cancer Group Consensus Statement on Clinical Trial Design for Patients with Bacillus Calmette-Guérin-exposed High-risk Non-muscle-invasive Bladder Cancer.

CONTEXT: A large proportion of patients with non-muscle-invasive bladder cancer (NMIBC) fall in the gap between bacillus Calmette-Guérin (BCG)-naïve and BCG-unresponsive disease. As multiple therapeutic agents move into this gray area, there is a critical need to define the disease state and establish recommendations for optimal trial design. OBJECTIVE: To develop a consensus on optimal trial design for patients with BCG-exposed NMIBC, defined as high-grade recurrence after BCG treatment that does not meet the criteria for BCG-unresponsive disease. EVIDENCE ACQUISITION: We conducted a literature review using the Cochrane Library, Medline, and Embase and a review of clinical trials in ClinicalTrials.gov as a basis to generate consensus recommendations for clinical trial design in BCG-exposed NMIBC. EVIDENCE SYNTHESIS: BCG-exposed NMIBC encompasses BCG resistance (presence of high-grade Ta or carcinoma in situ [CIS] at 3-mo evaluation after induction BCG) and delayed relapse. Randomized controlled trials are required to compare experimental therapies to a control arm receiving additional BCG, although ongoing BCG shortages may impact our ability to follow an optimal trial design. A placebo should be used in combination with BCG if the treatment arm includes BCG plus a study drug. Trials will either need to separate patients with and without CIS into two cohorts, or stratify by the presence of CIS at the time of randomization. If two cohorts are used, the primary endpoint for CIS patients should be complete response within a predetermined time. The primary endpoint in a cohort with Ta/T1 only, or if a single combined cohort is used, should be the duration of event-free survival. Suggested efficacy thresholds and corresponding sample sizes are provided. CONCLUSIONS: The International Bladder Cancer Group has developed recommendations regarding definitions, endpoints, and clinical trial design for BCG-exposed NMIBC to encourage uniformity among studies in this disease state. PATIENT SUMMARY: Our consensus provides a precise definition of the disease state for bladder cancer not invading the bladder muscle and exposed to bacillus Calmette-Guérin (BCG) treatment. Clear guidance for conducting optimal clinical trials in this disease setting was established and we believe that this will promote further progress in this field.

The 2021 Updated European Association of Urology Guidelines on Metastatic Urothelial Carcinoma.

CONTEXT: Treatment of metastatic urothelial carcinoma is currently undergoing a rapid evolution. OBJECTIVE: This overview presents the updated European Association of Urology (EAU) guidelines for metastatic urothelial carcinoma. EVIDENCE ACQUISITION: A comprehensive scoping exercise covering the topic of metastatic urothelial carcinoma is performed annually by the Guidelines Panel. Databases covered by the search included Medline, EMBASE, and the Cochrane Libraries, resulting in yearly guideline updates. EVIDENCE SYNTHESIS: Platinum-based chemotherapy is the recommended first-line standard therapy for all patients fit to receive either cisplatin or carboplatin. Patients positive for programmed death ligand 1 (PD-L1) and ineligible for cisplatin may receive immunotherapy (atezolizumab or pembrolizumab). In case of nonprogressive disease on platinum-based chemotherapy, subsequent maintenance immunotherapy (avelumab) is recommended. For patients without maintenance therapy, the recommended second-line regimen is immunotherapy (pembrolizumab). Later-line treatment has undergone recent advances: the antibody-drug conjugate enfortumab vedotin demonstrated improved overall survival and the fibroblast growth factor receptor (FGFR) inhibitor erdafitinib appears active in case of FGFR3 alterations. CONCLUSIONS: This 2021 update of the EAU guideline provides detailed and contemporary information on the treatment of metastatic urothelial carcinoma for incorporation into clinical practice. PATIENT SUMMARY: In recent years, several new treatment options have been introduced for patients with metastatic urothelial cancer (including bladder cancer and cancer of the upper urinary tract and urethra). These include immunotherapy and targeted treatments. This updated guideline informs clinicians and patients about optimal tailoring of treatment of affected patients.

100 years of Bacillus Calmette-Guérin immunotherapy: from cattle to COVID-19.

Bacillus Calmette-Guérin (BCG) is the most widely used vaccine worldwide and has been used to prevent tuberculosis for a century. BCG also stimulates an anti-tumour immune response, which urologists have harnessed for the treatment of non-muscle-invasive bladder cancer. A growing body of evidence indicates that BCG offers protection against various non-mycobacterial and viral infections. The non-specific effects of BCG occur via the induction of trained immunity and form the basis for the hypothesis that BCG vaccination could be used to protect against the severity of coronavirus disease 2019 (COVID-19). This Perspective article highlights key milestones in the 100-year history of BCG and projects its potential role in the COVID-19 pandemic.

Robot-assisted Radical Cystectomy Versus Open Radical Cystectomy in Bladder Cancer Patients: A Multicentre Comparative Effectiveness Study.

BACKGROUND: Radical cystectomy with pelvic lymph node dissection (PLND) and urinary diversion in patients with bladder cancer is known for its high risk of complications. Although open radical cystectomy (ORC) is regarded as the standard treatment, robot-assisted radical cystectomy (RARC) is increasingly used in practice, despite the fact that high-quality evidence comparing the effectiveness of both techniques is lacking. OBJECTIVE: To study the effectiveness of RARC compared with that of ORC, in terms of 90 d complications (Clavien-Dindo), health-related quality of life (HRQOL), and clinical outcomes. DESIGN, SETTING, AND PARTICIPANTS: A prospective comparative effectiveness study was conducted in 19 Dutch centres, expert in either ORC or RARC. Follow-up visits were scheduled at 30, 90, and 365 d. INTERVENTION: Standard ORC or RARC with PLND, using a standardised perioperative protocol. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was any-grade complications after 90 d. Secondary outcomes included HRQOL, complications (minor, major, 30 d, and 365 d), and clinical outcomes. Differences were calculated as risk differences (RDs) between the groups with 95% confidence intervals (CIs), adjusted for potential baseline differences by means of propensity score-based inverse probability of treatment weighting. RESULTS AND LIMITATIONS: Between March 2016 and November 2018, 348 patients were included (n = 168 for ORC, n = 180 for RARC). At 90 d, any-grade complication rates were 63% for ORC and 56% for RARC (RD -6.4%, 95% CI -17 to 4.5). Major complication rates were 15% for ORC and 16% for RARC (RD 0.9%, 95% CI -7.0 to 8.8). Total minor complication rates were 57% for ORC and 49% for RARC (RD -7.6%, 95% CI -19 to 3.6). Analyses showed no statistically significant differences in HRQOL between ORC and RARC. Some differences were found in the secondary outcomes in favour of either RARC or ORC. The major drawback inherent to the design comprises residual confounding. CONCLUSIONS: This multicentre comparative effectiveness study showed no statistically significant differences between ORC and RARC in terms of complications and HRQOL. PATIENT SUMMARY: This multicentre study did not show differences in overall complication rates, health-related quality of life, mortality, and clinical and oncological outcomes between open and robot-assisted radical cystectomy in bladder cancer patients.

Updated 2016 EAU Guidelines on Muscle-invasive and Metastatic Bladder Cancer.

CONTEXT: Invasive bladder cancer is a frequently occurring disease with a high mortality rate despite optimal treatment. The European Association of Urology (EAU) Muscle-invasive and Metastatic Bladder Cancer (MIBC) Guidelines are updated yearly and provides information to optimise diagnosis, treatment, and follow-up of this patient population. OBJECTIVE: To provide a summary of the EAU guidelines for physicians and patients confronted with muscle-invasive and metastatic bladder cancer. EVIDENCE ACQUISITION: An international multidisciplinary panel of bladder cancer experts reviewed and discussed the results of a comprehensive literature search of several databases covering all sections of the guidelines. The panel defined levels of evidence and grades of recommendation according to an established classification system. EVIDENCE SYNTHESIS: Epidemiology and aetiology of bladder cancer are discussed. The proper diagnostic pathway, including demands for pathology and imaging, is outlined. Several treatment options, including bladder-sparing treatments and combinations of treatment modalities (different forms of surgery, radiation therapy, and chemotherapy) are described. Sequencing of these modalities is discussed. Potential indications and contraindications, such as comorbidity, are related to treatment choice. There is a new paragraph on organ-sparing approaches, both in men and in women, and on minimal invasive surgery. Recommendations for chemotherapy in fit and unfit patients are provided including second-line options. Finally, a follow-up schedule is provided. CONCLUSIONS: The current summary of the EAU Muscle-invasive and Metastatic Bladder Cancer Guidelines provides an up-to-date overview of the available literature and evidence dealing with diagnosis, treatment, and follow-up of patients with metastatic and muscle-invasive bladder cancer. PATIENT SUMMARY: Bladder cancer is an important disease with a high mortality rate. These updated guidelines help clinicians refine the diagnosis and select the appropriate therapy and follow-up for patients with metastatic and muscle-invasive bladder cancer.

Increasing age is not associated with toxicity leading to discontinuation of treatment in patients with urothelial non-muscle-invasive bladder cancer randomised to receive 3 years of maintenance bacille Calmette-Guérin: results from European Organisation for Research and Treatment of Cancer Genito-Urinary Group study 30911.

OBJECTIVE: To determine the relationship of age to side-effects leading to discontinuation of treatment in patients with stage Ta-T1 non-muscle-invasive bladder cancer (NMIBC) treated with maintenance bacille Calmette-Guérin (BCG). PATIENTS AND METHODS: We evaluated toxicity for 487 eligible patients with intermediate- or high-risk Ta-T1 (without carcinoma in situ) NMIBC randomised to receive 3 years of maintenance BCG therapy (247 BCG alone and 240 BCG + isoniazid) in European Organisation for Research and Treatment of Cancer Genito-Urinary Group trial 30911. The percentage of patients who stopped for toxicity and the number of treatment cycles that they received were compared in four age groups, ≤60, 61-70, 71-75 and >75 years, using the Mantel-Haenszel chi-square test for trend. RESULTS: The percentage of patients stopping BCG for toxicity was 17.9% in patients aged ≤60 years, 21.9% in patients aged 61-70 years, 22.9% in patients aged 71-75 years, and 16.4% in patients aged >75 years (P = 0.90). For both systemic and local side-effects, there was likewise no significant difference. CONCLUSION: In patients with intermediate- and high-risk Ta-T1 NMIBC treated with BCG, no differences in toxicity as a reason for stopping treatment were detected based on patient age.

Urinary cytokines in patients treated with intravesical mitomycin-C with and without hyperthermia.

OBJECTIVES: To explore whether urinary cytokine and chemokine (CK) levels differed between cold mitomycin-C (cold-MMC)-treated patients and chemohyperthermia (C-HT)-treated patients, to shed light on the possible molecular mechanisms that might explain the superior outcome of C-HT. Furthermore, CK-differences were explored between C-HT responders and C-HT non-responders. METHODS: Twelve NMIBC patients were included. Nine received six-weekly C-HT, and three received four-weekly cold-MMC instillations. Urine was collected on 8-12 time points before and after every treatment. MDC, IL-2, IL-6, IL-8, IP-10, MCP-1 and RANTES were determined by Luminex(®)-analysis. RESULTS: Elevated urinary CK levels were observed in both groups after treatment. In general, CK-peaks were lower in the cold-MMC group in comparison with levels in the C-HT group. Significant higher MCP-1 and IL-6 levels were observed in C-HT-treated patients. Additionally, significant cumulative effects were observed for IP-10 and IL-2. However, IP-10 and IL-2 levels did not significantly differ between treatments. MDC levels after the first week of treatment were significantly higher in the C-HT responders compared with the non-responders. CONCLUSION: MMC treatment leads to elevated urinary CK levels with significantly higher MCP-1 and IL-6 levels in C-HT-treated patients. Increased MDC levels after the first C-HT instillation appear to be related to good clinical outcome and might be of additional value to personalize treatment. Studies involving more patients and longer follow-up are needed to substantiate this observation.

The prognostic value of family history among patients with urinary bladder cancer.

A history of urinary bladder cancer (UBC) in first-degree relatives increases UBC risk by twofold. The influence of positive family history on UBC prognosis is unknown. Here, we investigated association of first-degree UBC family history with clinicopathological characteristics and prognosis of UBC patients. Detailed clinical data of 1,465 non-muscle-invasive bladder cancer (NMIBC) and 250 muscle-invasive or metastatic bladder cancer (MIBC) patients, diagnosed from 1995 to 2010, were collected through medical file review. Competing risk analyses were used to compare recurrence-free survival (RFS) and progression-free survival (PFS) of NMIBC patients according to self-reported UBC family history. Overall survival in MIBC patients was estimated using Kaplan-Meier analysis. The added value of family history in prediction of NMIBC prognosis was quantified with Harrell's concordance-index. Hundred (6.8%) NMIBC and 14 (5.6%) MIBC patients reported UBC in first-degree relatives. Positive family history was statistically significantly associated with smaller tumor size and non-significantly with more favorable distribution of other tumor characteristics. In univariable analyses, positive family history correlated with longer RFS (p = 0.11) and PFS (p = 0.04). Hazard ratios for positive vs. negative family history after adjustment for clinicopathological characteristics were 0.75 (95% CI = 0.53-1.07) and 0.45 (95% CI = 0.18-1.12) for RFS and PFS, respectively. Five familial and 48 sporadic MIBC patients (Kaplan-Meier 10-year risk: 41% and 25%) died within 10 years. Family history did not improve the c-index of prediction models. This study shows that a first-degree family history of UBC is not clearly associated with NMIBC prognosis. Family history does not aid in prediction of NMIBC recurrence or progression.

The effect of photochemical internalization of bleomycin in the treatment of urothelial carcinoma of the bladder: an in vitro study.

OBJECTIVES: In this in vitro study, we determined whether meso-tetraphenyl chlorin disulphonate (TPCS2a)-based photochemical delivery of bleomycin was able to potentiate the cytotoxicity of bleomycin on bladder cancer cells. MATERIALS AND METHODS: The human RT4, RT112, 253J, T24, and rat AY-27 urothelial carcinoma cell lines were used. Cells were seeded in 96-well plates. TPCS2a was added to the growth medium and the plates were incubated overnight. Cells were then resuspended in TPCS2a-free culture medium and incubated for 3 hours. Subsequently, cells were treated for 60 minutes with increasing doses of epirubicin, gemcitabine, mitomycin C, or bleomycin followed by illumination for different periods. Cell viability was measured with a colorimetric assay after 72 hours. RESULTS: For the single treatments, in all 5 cell lines a dose-dependent inhibition of cell proliferation was observed. This was seen both after treatment with TPCS2a-based photodynamic therapy (PDT), as well as after treatment with either bleomycin or one of the control chemotherapeutic agents. After treatment with PDT (240-s illumination), bleomycin 9.0 µM, and the combination of these treatments, relative survival percentages were 89.2 ± 13.0, 70.2 ± 8.9, and 30.5 ± 6.1, respectively, in the T24 cell line. After treatment with PDT (120-s illumination), bleomycin 27 µM and the combination of these treatments, relative survival percentages were 93.6 ± 15.7, 74.7 ± 9.6, and 30.0 ± 11.1, respectively, in the AY-27 cell line. In both cell lines, PDT combined with bleomycin showed significantly (P<0.001) higher cell kill than the sum of the single treatments, suggesting a photochemical internalization effect. CONCLUSIONS: TPCS2a-based photochemical internalization of bleomycin showed a significant, at least, additive antiproliferative activity against human and rat urothelial carcinoma cells in vitro. Thus, photochemical internalization may have therapeutic potential as an intravesical strategy against bladder cancer. As the effect is heterogeneous, biomarker studies are warranted to be able to predict the effects of a photochemical internalization-based treatment.

Choice between prostatectomy and radiotherapy when men are eligible for both: a randomized controlled trial of usual care vs decision aid.

UNLABELLED: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Many patients are eligible for more than one treatment option for prostate cancer. In usual care, urologists have a large influence on the treatment choice. Decision aids, providing balanced information on the pros and cons of different treatment options, improve the match between patient preferences and treatment received. In men eligible for both surgery and external beam radiotherapy, treatment choice differed by hospital. Across the participating hospitals, the decision aid consistently led to fewer patients remaining undecided on their treatment preference and more patients choosing brachytherapy. OBJECTIVES: To examine the treatment choice for localized prostate cancer in selected men who were eligible for both prostatectomy and radiotherapy. To examine whether increased patient participation, using a decision aid, affected the treatment choice. PATIENTS AND METHODS: From 2008 to 2011, 240 patients with localized prostate cancer were enrolled from three separate hospitals. They were selected to be eligible for both prostatectomy and external beam radiotherapy. Brachytherapy was a third option for about half of the patients. In this randomized controlled trial, patients were randomized to a group which only discussed their treatment with their specialist (usual care group) and a group which received additional information from a decision aid presented by a researcher (decision aid group). The decision aid was based on a literature review. Predictors of treatment choice were examined. RESULTS: Treatment choice was affected by the decision aid (P = 0.03) and by the hospital of intake (P < 0.001). The decision aid led to more patients choosing brachytherapy (P = 0.02) and fewer patients remaining undecided (P < 0.05). Prostatectomy remained the most frequently preferred treatment. Age, tumour characteristics or pretreatment urinary, bowel or erectile functioning did not affect the choice in this selected group. Patients choosing brachytherapy assigned more weight to convenience of the procedure and to maintaining erectile function. CONCLUSIONS: Traditionally, patient characteristics differ between surgery and radiotherapy groups, but not in this selected group of patients. Men eligible for both prostatectomy and radiotherapy mostly preferred prostatectomy, and the treatment choice was influenced by the hospital they visited. Giving patients evidence-based information, by means of a decision aid, led to an increase in brachytherapy.
