Abstract
INTRODUCTION The aim of this study was to analyze the reasons for intravesical BCG interruption in clinical practice. BCG for at least one year is advocated as the best regimen to treat high-risk non-muscle invasive bladder cancer (NMIBC). However, almost 50% of patients don't complete it. Toxicity accounts for 10% of dropouts in international trials. MATERIALS AND METHODS Patients with T1HG NMIBC undergoing 1-year BCG were enrolled in this study. BCG was administered for one year. Toxicity and causes of treatment interruption were recorded. RESULTS A total of 411 patients were enrolled in the study. Out of these total number of patients, 380 (92.5%) completed the induction cycle and 215 (52.3%) completed one year. Toxicity requiring interruption or postponement was recorded in 25 (6.1%) and 60 (14.6%) patients. Ninety-three patients (30.2%) stopped BCG, 9 (9.7%) for recurrence and 14 (15.1%) for grade-3 toxicity. Intriguingly, 55 (59.1%) patients refused BCG due to mild discomfort and deterioration in quality of social life. CONCLUSIONS Grades 2-3 toxicity causes BCG interruption in a few cases. Almost 60% of interruptions are attributable to persistent grade-1 toxicity, which is inadequately treated.

Abstract
BACKGROUND Intravesical bacillus Calmette-Guerin (BCG) therapy is an effective and widely used treatment for superficial bladder carcinoma. Local complications are frequent whereas systemic complications are rare but can be serious, and their management is not well known. METHODS We describe retrospectively the records of 22 patients treated in 3 infectious disease departments, for complications related to intravesical BCG therapy as treatment of bladder cancer. RESULTS All the patients were male, with a median age of 68 years (range 56-88). Complications occurred after a median of 5 instillations (range 1-11) and were observed within 24 h following BCG instillation for 14 patients. Common symptoms were fever (n = 20), impaired general condition (n = 14), and shortness of breath (n = 7). Six patients had a systemic septic reaction leading to transfer into the intensive care unit for five of them. Lung infiltration was the most frequent presentation (n = 11). Mycobacterium bovis was isolated from only two patients, but histology showed the presence of a granuloma in nine patients. Antimycobacterial treatment was initialized in 17 patients; the outcome was favorable in 16 patients, with a median length of symptoms resolution of 22.5 days (range 5-425 days). Eleven patients received corticosteroids in addition to specific treatment and had a more rapid improvement. One patient died with disseminated BCGitis proved by biopsy. CONCLUSIONS Complications following intravesical BCG therapy are rare but can be severe and fatal. Histology seems to be the method that contributes most in confirmation of the diagnosis. Antimycobacterial therapy is effective, and probably more efficient when combined with corticosteroids, but the regimen and duration of the treatment are not standardized.

Abstract
INTRODUCTION Patients with high-risk non-muscle invasive bladder cancer (NMIBC) need adjuvant intravesical treatment after surgery. Although bacillus Calmette-Guérin (BCG) is highly effective, new adjuvant treatments to decrease recurrences and toxicity have been studies. We performed a retrospective propensity score-matched study to compare the efficacy of BCG and chemohyperthermia (C-HT). METHODS We included 1937 patients diagnosed with bladder cancer between January 2004 and January 2014. The primary efficacy endpoint was recurrence-free interval. Patients treated with C-HT were matched with patients treated with BCG using propensity score-matched analysis. Cox-regression models were used to estimate the association between intravesical treatments and the presence of recurrence and progression. RESULTS Of the 710 patients treated with intravesical treatments, 40 and 142 were eligible for inclusion in C-HT and BCG groups, respectively. Following case matching, there were no differences in patient or tumour characteristics between treatment groups. The 2-year recurrence-free interval in C-HT and BCG groups were 76.2% and 93.9%, respectively (p = 0.020). C-HT treatment (hazard ratio [HR] 5.42; 95% confidence interval [CI] 1.11-26.43; p = 0.036) and high-grade tumour (HR 4.60; 95% CI 1.01-20.88; p = 0.048) are associated with an elevated odds of tumour recurrence. In multivariate Cox-regression analysis, there was no significant difference between C-HT and BCG in the odds of recurrence (p = 0.054). There were no differences in progression between C-HT and BCG. CONCLUSION C-HT is not as effective treatment as BCG in high-risk NMIBC patients who are BCG-naive. Although, there were no significant difference in the odds of recurrence, recurrence-free interval is significantly improved by the administration of BCG.

Abstract
The treatment of nonmuscle-invasive urothelial carcinoma with bacillus Calmette-Guérin (BCG) represents the importance of immunotherapy in the treatment of cancer. Despite its clinical efficacy, up to 30% of patients will ultimately experience progression to muscle-invasive disease. This, along with an improved understanding of the biologic pathways involved, has led to efforts to improve, enhance, or alter the immune response in the treatment of urothelial carcinoma. A number of novel therapeutic approaches currently are being pursued, including recombinant BCG to induce T helper type 1 (Th1) immune responses, nonlive Mycobacterium agents, targeted agents toward cancer-associated antigens, immune-modulating vaccines, and adoptive T-cell therapies. Here, we review the current and future immunotherapy treatment options for patients with urothelial cancer.

Abstract
It is nearly 40 years since Bacillus Calmette-Guérin (BCG) was first used as an immunotherapy to treat superficial bladder cancer. Despite its limitations, to date it has not been surpassed by any other treatment. As a better understanding of its mechanism of action and the clinical response to it have evolved, some of the questions around optimal dosing and treatment protocols have been answered. However, its potential for toxicity and failure to produce the desired clinical effect in a significant cohort of patients presents an ongoing challenge to clinicians and researchers alike. This review summarizes the evidence behind the established mechanism of action of BCG in bladder cancer, highlighting the extensive array of immune molecules that have been implicated in its action. The clinical aspects of BCG are discussed, including its role in reducing recurrence and progression, the optimal treatment regime, toxicity and, in light of new evidence, whether or not there is a superior BCG strain. The problems of toxicity and non-responders to BCG have led to development of new techniques aimed at addressing these pitfalls. The progress made in the laboratory has led to the identification of novel targets for the development of new immunotherapies. This includes the potential augmentation of BCG with various immune factors through to techniques avoiding the use of BCG altogether; for example, using interferon-activated mononuclear cells, BCG cell wall, or BCG cell wall skeleton. The potential role of gene, virus, or photodynamic therapy as an alternative to BCG is also reviewed. Recent interest in the immune check point system has led to the development of monoclonal antibodies against proteins involved in this pathway. Early findings suggest benefit in metastatic disease, although the role in superficial bladder cancer remains unclear.

Abstract
BACKGROUND Non-muscle-invasive bladder cancer with a low-grade differentiation represents a special challenge. METHOD Although urine cytology is still the most reliable and effective urine-based marker and there are no substantial novel aspects in this field, photodynamic diagnostics have the most important value in transurethral resection of the bladder (TURB) of high-grade T1 tumors and new techniques, such as hybrid knife TURB are coming up. The histopathological assessment of T1 tumors can be supplemented by a description of the exact penetration depth, so-called substaging and the invasion pattern. RESULTS Intravesicle therapy with Bacillus Calmette-Guèrin (BCG) represents the gold standard and a pillar of bladder-preserving therapy and should be planned as maintenance therapy for at least 1 year. With the right risk constellation cystectomy is a safe and proven concept for high-grade bladder cancer, even without proof of muscle invasion.

Abstract
The use of antibiotics has become increasingly disfavored as more multidrug resistant pathogens are on the rise. A promising alternative to the use of these conventional drugs includes antimicrobial peptides or host-defense peptides. These peptides typically consist of short amino acid chains with a net cationic charge and a substantial portion of hydrophobic residues. They mainly target the bacterial cell membrane but are also capable of translocating through the membrane and target intracellular components, making it difficult for bacteria to gain resistance as multiple essential cellular processes are being targeted. The use of these peptides in the field of biomedical therapies has been examined, and the different approaches to using them under various settings are constantly being discovered. In this review, we discuss the current and potential applications of these host-defense peptides in the field of urology. Besides the use of these peptides as antimicrobial agents, the value of these biological molecules has recently been expanded to their use as antitumor and anti-kidney-stone agents.

Abstract
For non-muscle invasive bladder cancer, a disease with a considerable epidemiological and socio-economic impact, the introduction of the Guidelines has always evoked as a tool for the resolution of long-standing disputes in terms of diagnosis and therapy. Check the degree of routine clinical practice adherence to the Recommendations is for this disease, more than for other uro-oncology pathology, an urgent need felt by the urological community. To assess the level of Guidelines adherence's, and study issues related to the paths of diagnosis and treatment of non-muscle invasive bladder cancer, and identifying the processes actually implemented in daily clinical practice, a series of case studies has submitted to a group of experts. The acknowledgement study allowed testing the impact of the current Evidence Based Medicine Recommendations in the everyday clinical practice identifying strengths and weaknesses. Questions Responses Analysis' of 5 clinical cases (Ta low grade, T1 low grade, T1 high grade, T1 high grade + CIS, Ta low-grade multiple recurrence) showed a moderate amendment to the European Association of Urology (EAU)-Guidelines. On the other hand, it was emphasized that there are clear discrepancies between what should be done, in accordance with the Evidence Based Medicine Recommendations, and what is actually do in everyday clinical practice. The most common reason for the low Recommendations adherences are structural and organizational practical limitations.

Abstract
PURPOSE To determine the safety and toxicities of sequential MMC (mitomycin C) + BCG (bacillus Calmette-Guérin) in patients with non-muscle-invasive bladder cancer (NMIBC) and explore evidence for potentiation of BCG activity by MMC. EXPERIMENTAL DESIGN A 3 + 3 phase I dose-escalation trial of six weekly treatments was conducted in patients with NMIBC. MMC (10, 20, or 40 mg) was instilled intravesically for 30 minutes, followed by a 10-minute washout with gentle saline irrigation and then instillation of BCG (half or full strength) for 2 hours. Urine cytokines were monitored and compared with levels in a control cohort receiving BCG only. Murine experiments were carried out as described previously. RESULTS Twelve patients completed therapy, including 3 patients receiving full doses. The regimen was well tolerated with no treatment-related dose-limiting toxicities. Urinary frequency and urgency, and fatigue were common. Eleven (91.7%) patients were free of disease at a mean (range) follow-up of 21.4 (8.4-27.0) months. Median posttreatment urine concentrations of IL2, IL8, IL10, and TNFα increased over the 6-week treatment period. A greater increase in posttreatment urinary IL8 during the 6-week period was observed in patients receiving MMC + BCG compared with patients receiving BCG monotherapy. In mice, intravesical MMC + BCG skewed tumor-associated macrophages (TAM) toward a beneficial M1 phenotype. CONCLUSIONS Instillation of sequential MMC + BCG is safe tolerable up to 40-mg MMC plus full-strength BCG. This approach could provide improved antitumor activity over BCG monotherapy by augmenting beneficial M1 TAMs.

Abstract
Bacillus Calmette-Guérin (BCG) is the most effective intravesical immunotherapy for superficial bladder cancer. Although generally well tolerated, BCG-related infectious complications may occur following instillation. Much of the current knowledge about this complication comes from single case reports, with heterogeneous diagnostic and therapeutic approaches and no investigation on risk factors for its occurrence. We retrospectively analyzed 256 patients treated with intravesical BCG in our institution during a 6-year period, with a minimum follow-up of 6 months after the last instillation. We also conducted a comprehensive review and pooled analysis of additional cases reported in the literature since 1975. Eleven patients (4.3%) developed systemic BCG infection in our institution, with miliary tuberculosis as the most common form (6 cases). A 3-drug antituberculosis regimen was initiated in all but 1 patient, with a favorable outcome in 9/10 cases. There were no significant differences in the mean number of transurethral resections prior to the first instillation, the time interval between both procedures, the overall mean number of instillations, or the presence of underlying immunosuppression between patients with or without BCG infection. We included 282 patients in the pooled analysis (271 from the literature and 11 from our institution). Disseminated (34.4%), genitourinary (23.4%), and osteomuscular (19.9%) infections were the most common presentations of disease. Specimens for microbiologic diagnosis were obtained in 87.2% of cases, and the diagnostic performances for acid-fast staining, conventional culture, and polymerase chain reaction (PCR)-based assays were 25.3%, 40.9%, and 41.8%, respectively. Most patients (82.5%) received antituberculosis therapy for a median of 6.0 (interquartile range: 4.0-9.0) months. Patients with disseminated infection more commonly received antituberculosis therapy and adjuvant corticosteroids, whereas those with reactive arthritis were frequently treated only with nonsteroidal antiinflammatory drugs (p < 0.001 for all comparisons). Attributable mortality was higher for patients aged ≥65 years (7.4% vs 2.1%; p = 0.091) and those with disseminated infection (9.9% vs 3.0%; p = 0.040) and vascular involvement (16.7% vs 4.6%; p = 0.064). The scheduled BCG regimen was resumed in only 2 of 36 patients with available data (5.6%), with an uneventful outcome. In the absence of an apparent predictor of the development of disseminated BCG infection after intravesical therapy, and considering the protean variety of clinical manifestations, it is essential to keep a high index of suspicion to initiate adequate therapy promptly and to evaluate carefully the risk-benefit balance of resuming intravesical BCG immunotherapy.

Abstract
Bacillus Calmette-Guérin (BCG) has been used in the intravesical treatment of urothelial bladder cancer (UBC) for three decades. Despite its efficacy, intravesical BCG therapy is associated with some limitations such as side effects and BCG failure, which have inspired multiple ways to improve it. Recent advances have focused on recombinant BCG (rBCG) which provides a novel tactic for modification of BCG. To date, a number of rBCG strains have been developed and demonstrated to encourage efficacy and safety in preclinical and clinical studies. This review summarizes current rBCG strategies, concerns and future directions in UBC immunotherapy with an intention to encourage further research and eventually to inform clinical decisions.

Abstract
PURPOSE Low, intermediate and high risk categories have been defined to help guide the treatment of patients with nonmuscle invasive bladder cancer (Ta, T1, CIS). However, while low and high risk disease has been well classified, the intermediate risk category has traditionally comprised a heterogeneous group that does not fit into either of these categories. As a result, many urologists remain uncertain about the categorization of patients as intermediate risk as well as the selection of the most appropriate therapeutic option for this patient population. We review the current literature and clinical practice guidelines on intermediate risk nonmuscle invasive bladder cancer and, based on our findings, provide urologists with a better understanding of this heterogeneous risk group as well as practical recommendations for the treatment of intermediate risk patients. MATERIALS AND METHODS The IBCG analyzed published clinical trials, meta-analyses and current clinical practice guidelines on intermediate risk nonmuscle invasive bladder cancer available as of September 2013. The definitions of intermediate risk, patient outcomes and guideline recommendations were considered, as were the limitations of the available literature and additional parameters that may be useful in guiding treatment decisions in intermediate risk patients. RESULTS Current definitions and management recommendations for intermediate risk nonmuscle invasive bladder cancer vary. The most simple and practical definition is that proposed by the IBCG and the AUA of multiple and/or recurrent low grade Ta tumors. The IBCG suggests that several factors should be considered in clinical decisions in intermediate risk disease, including number (greater than 1) and size (greater than 3 cm) of tumors, timing (recurrence within 1 year) and frequency (more than 1 per year) of recurrence, and previous treatment. In patients without these risk factors a single, immediate instillation of chemotherapy is advised. In those with 1 to 2 risk factors adjuvant intravesical therapy (intravesical chemotherapy or maintenance bacillus Calmette-Guérin) is recommended, and previous intravesical therapy should be considered when choosing between these adjuvant therapies. For those patients with 3 to 4 risk factors, maintenance bacillus Calmette-Guérin is recommended. It is also important that all intermediate risk patients are accurately risk stratified at initial diagnosis and during subsequent followup. This requires appropriate transurethral resection of the bladder tumor, vigilance to rule out carcinoma in situ or other potential high risk tumors, and review of histological material directly with the pathologist. CONCLUSIONS Intermediate risk disease is a heterogeneous category, and there is a paucity of independent studies comparing therapies and outcomes in subgroups of intermediate risk patients. The IBCG has proposed a management algorithm that considers tumor characteristics, timing and frequency of recurrence, and previous treatment. Subgroup analyses of intermediate risk subjects in pivotal EORTC trials and meta-analyses will be important to validate the proposed algorithm and support clear evidence-based recommendations for subgroups of intermediate risk patients.
