Abstract
Bladder cancer (BC) is one of the most prevalent malignancies in men. Understanding molecular characteristics via studying signaling pathways has made tremendous breakthroughs in BC therapies. Thus, targeted therapies including immune checkpoint inhibitors (ICIs), antibody-drug conjugates (ADCs), and tyrosine kinase inhibitor (TKI) have markedly improved advanced BC outcomes over the last few years. However, the considerable patients still progress after a period of treatment with current therapeutic regimens. Therefore, it is crucial to guide future drug development to improve BC survival, based on the molecular characteristics of BC and clinical outcomes of existing drugs. In this perspective, we summarize the applications and benefits of these targeted drugs and highlight our understanding of mechanisms of low response rates and immune escape of ICIs, ADCs toxicity, and TKI resistance. We also discuss potential solutions to these problems. In addition, we underscore the future drug development of targeting metabolic reprogramming and cancer stem cells (CSCs) with a deep understanding of their signaling pathways features. We expect that finding biomarkers, developing novo drugs and designing clinical trials with precisely selected patients and rationalized drugs will dramatically improve the quality of life and survival of patients with advanced BC.

Abstract
Introduction With the shortage of bacillus Calmette-Guérin (BCG) vaccine, it is important to find an alternative to BCG instillation, which is the most commonly used adjuvant treatment for non-muscle-invasive bladder cancer (NMIBC) patients after transurethral resection of bladder tumor treatment (TURBt) to delay tumor recurrence. Hyperthermia intravesical chemotherapy (HIVEC) with mitomycin C (MMC) is a potential treatment choice. We aim to compare HIVEC with BCG instillation for the preventive efficacy of bladder tumor recurrence and progression. Methods A network meta-analysis (NMA) was taken with MMC instillation and TURBt as the attached comparators. Randomized controlled trials (RCTs) with NIMBC patients after TURBt were included. Articles with pure BCG unresponsive patients and combined therapies were excluded. The study protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO, CRD42023390363). Results It was found that HIVEC had a non-significant 22% relative reduction in bladder tumor recurrence compared with BCG instillation [HIVEC vs. BCG: HR 0.78, 95% credible interval (CrI) 0.55-1.08] and a nonsignificant higher risk of bladder tumor progression (BCG vs. HIVEC: HR 0.77, 95% CrI 0.22-3.03). Discussion HIVEC is a potential alternative to BCG, and it is expected to be the standard therapy for NMIBC patients after TURBt during the global shortage of BCG. Systematic Review Registration PROSPERO identifier, CRD42023390363.

Abstract
BCG is a live attenuated strain of Mycobacterium bovis that is primarily used as a vaccine against tuberculosis. In the past four decades, BCG has also been used for the treatment of non-muscle invasive bladder cancer (NMIBC). In patients with NMIBC, BCG reduces the risk of tumor recurrence and decreases the likelihood of progression to more invasive disease. Despite the long-term clinical experience with BCG, its mechanism of action is still being elucidated. Data from animal models and from human studies suggests that BCG activates both the innate and adaptive arms of the immune system eventually leading to tumor destruction. Herein, we review the current data regarding the mechanism of BCG and summarize the evidence for its clinical efficacy and recommended indications and clinical practice.

A prospective comparative study to assess the efficacy and tolerability of 2 different doses of intravesical bacillus Calmette-Guerin (BCG) in patients with non-muscle-invasive bladder cancer. Urol Oncol 2020; 38:433-439. [PMID: 32037199 DOI: 10.1016/j.urolonc.2020.01.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2019] [Revised: 12/06/2019] [Accepted: 01/08/2020] [Indexed: 11/30/2022]
Abstract
BACKGROUND Bacillus Calmette-Guerin (BCG) is widely used as an immunotherapeutic agent and recommended in management of non-muscle-invasive bladder cancer (NMIBC). There is no consensus on the optimal dose of the BCG. However, dose reduction has been assessed to decrease the side effects following instillation of BCG. This study compared the efficacy and safety of 80 and 120 mg doses of Sii Onco BCG (Moscow I, Russian strain) in patients with NMIBC. METHODS Patients with histologically confirmed, completely resected solitary or multiple Ta or T1 (with or without carcinoma in situ), grade 1 to 3 urothelial carcinoma of the bladder were included. After transurethral resection of the tumor, repeated intravesical instillations with Sii Onco BCG (80 or 120 mg) were administered, following the induction and 3 weekly maintenance schedule (at 3, 6, 9, 15, 21, 27, and 33 months). Recurrence and progression of the tumor were monitored at scheduled time intervals using cystoscopy. RESULTS A total of 104 eligible patients were enrolled to receive 80 mg (n = 51) dose or 120 mg dose (n = 53) of Sii Onco BCG. On completion of 3 years follow-up, recurrence-free survival rate of 84.31% and 86.79% and progression-free survival rate of 84.31% and 94.34% were observed for 80 and 120 mg groups, respectively; difference being statistically nonsignificant. CONCLUSION Both, 80 and 120 mg doses of Sii Onco BCG are effective and safe for prophylaxis and management of NMIBC.

Should intravesical Bacillus Calmette-Guerin (BCG) treatment be administered to patients with T0 after repeat transurethral resection of bladder tumor in patients with high-risk non-muscle invasive bladder cancer? PLoS One 2018; 13:e0208267. [PMID: 30496283 PMCID: PMC6264801 DOI: 10.1371/journal.pone.0208267] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2018] [Accepted: 11/14/2018] [Indexed: 11/18/2022] Open
Abstract
We evaluated the effect of intravesical Bacillus Calmette-Guerin (BCG) and BCG maintenance therapy on the prognosis of patients with T0 after repeat transurethral resection of bladder mass (TURBT). This retrospective analysis involved 427 patients who underwent repeat TURBT within 6 weeks after initial TURBT from 2007 to 2016. Repeat TURBT was performed in patients with high-risk criteria. Patients who achieved T0 after repeat TURBT did or did not receive intravesical BCG therapy. Patients were divided into three groups: non-BCG, BCG induction, and BCG maintenance groups. The study included 106 patients who achieved T0 after repeat TURBT. The median follow-up was 63 months. There were no significant differences in T stage among the three groups. High grade ratio (p = 0.001) and concomitant CIS ratio (p = 0.037) were significantly higher in the BCG maintenance than in the other two groups. The recurrence rates in the non-BCG, BCG induction, and BCG maintenance groups were 46.2%, 28.3%, and 19.2%, respectively (p = 0.043). Recurrence-free survival was significantly higher in the BCG maintenance group than in the BCG induction group (p = 0.032). Progression-free survival was also higher in the BCG maintenance group than in the BCG induction group, but the difference was not significant (p = 0.056). Multivariate Cox regression analysis showed that only intravesical BCG maintenance therapy was significantly associated with recurrence (hazard ratio 0.016, p = 0.016). In high risk NMIBC patients, intravesical BCG maintenance treatment is required even at T0 after repeat TURBT. Intravesical BCG maintenance therapy of patients with T0 after TURBT reduces recurrence.

Abstract
The urologist must prevent, identify and properly treat the complications of intravesical chemotherapy and immunotherapy. Both local and systemic toxicity of adjuvant intravesical therapy is herein analyzed. Topical toxicity is mainly due to the inflammation induced by the contact between the instilled agent and the bladder mucosa. Material and Methods The factors predisposing to topical toxicity must be identified and removed before starting the treatment. The choice of the agent, its dose, concentration and dosage must be tailored, whenever possible, to the presence of the above mentioned factors. Mitomycin and BCG can rarely provoke chronic cystitis, severely compromising bladder function. Results The most dangerous complication of early intravesical chemotherapy is the instillation in presence of an unrecognized bladder perforation. Flu-like syndrome, fever, chills, arthralgia are reported in almost 20% of patients receiving BCG. If fever persists for more than 48 hours or exceeds 38.5 °C, isoniazid must be administered and BCG stopped until complete remission. BCG sepsis is a rare but severe complication that must be promptly recognized and treated. If not, a life-threatening multi-organ failure syndrome can arise. Isoniazid and rifampicin, adding ethambutol when required, must be administered for a prolonged period until complete remission. Conclusions Granulomatous lesions represent the main other rare systemic complications of BCG therapy. Systemic toxicity of intravesical chemotherapy is rare, due to the high molecular weight of the drugs, limiting systemic absorption.

Abstract
An unmet need exists for patients with high-risk non-muscle-invasive bladder cancer for whom bacille Calmette-Guérin (BCG) has failed and who seek further bladder-sparing approaches. This shortcoming poses difficult management dilemmas. This review explores previously investigated first-line intravesical therapies and discusses emerging second-line treatments for the heterogeneous group of patients for whom BCG has failed. The myriad of recently published and ongoing trials assessing novel salvage intravesical treatments offer promise to patients who both seek an effective cure and want to avoid radical surgery. However, these trials must carefully be contextualized by specific patient, tumor, and recurrence characteristics. As data continue to accumulate, there will potentially be a role for these agents as second-line or even first-line intravesical therapies. Cancer 2017;123:390-400. © 2016 American Cancer Society.

Abstract
Objective To evaluate the efficacy and safety of low-dose (45 mg) intravesical bacille Calmette–Guérin (BCG) therapy in the treatment of patients with non-muscle-invasive bladder cancer (NMIBC), as intravesical BCG is the most acceptable adjuvant therapy for NMI transitional cell carcinoma of the bladder. However, in the standard regimen, undesirable effects are the main cause of treatment discontinuation. Patients and methods The present study included 37 men with primary NIMBC. All patients underwent complete TURB and 2 weeks later, a 6-week course of 45 mg BCG diluted in 50 mL isotonic saline was instilled into the bladder and retained for 2 h. Patients were evaluated for BCG efficacy (recurrence with or without progression) and safety by documentation of minor and/or major side-effects. Results There were no major or severe side-effects and no treatment discontinuations. Local adverse effects occurred in 20 patients, while systemic effects, in the form of fever, occurred in six patients (16.2%). There was recurrence in 14 patients (37.8%) after 18–34 months, with disease progression (muscle invasion) in four (10.8%) after 6–18 months. The recurrence index was 0.39/100 patients/month and the mean (range) tumour-free period was 30.97 (7–36) months. Conclusion Low-dose BCG intravesical therapy is an effective adjuvant treatment in NMIBC. However, this needs to be validated in future studies and in comparison with other proposed doses and/or regimens.

Abstract
BCG vaccine is the one of the most widely used vaccines globally. Local complications are commonly seen but approach to management varies. Injection site reactions and non-suppurative lymphadenitis can be managed conservatively. Aspiration may be beneficial in suppurative lymphadenitis. Antimicrobials and surgery are rarely required except for non-resolving cases.
Background Bacille Calmette-Guérin (BCG) vaccine is one of the most widely used vaccines globally. Management of local BCG complications (injection site reactions and suppurative or non-suppurative lymphadenitis) varies between clinicians, and the optimal approach remains uncertain. Aim To determine the clinical features, management and outcome of BCG complications at two large acute hospitals in London, United Kingdom. Methods All children presenting with complications of BCG vaccination between January 2008 and December 2013 were included in this observational study. Medical and electronic laboratory records were reviewed to determine clinical features, treatment and outcome. Results Sixty children presented with adverse reactions. Two-thirds (65%) presented with BCG lymphadenitis, one-third (30%) presented with injection site complications and two children (3%) presented with both injection site reaction and lymphadenitis; only one child (2%) had disseminated BCG disease. The majority (88%) of children with injection site reactions were managed conservatively; overall, 95% showed complete resolution within 6 months. Among children with lymphadenitis, 46% were managed conservatively, whilst 54% had anti-tuberculous therapy and/or a procedure (aspiration mostly, or surgery); complete resolution was seen in 59% of cases. Conclusions Injection site reactions and non-suppurative lymphadenitis were generally managed conservatively, with good outcomes. There was more variation in management and outcome of suppurative lymphadenitis and the optimal approach remains uncertain.

Abstract
Since its introduction almost 40 years ago, intravesical BCG for non-muscle invasive bladder cancer remains one of the most successful cancer immunotherapies. However, up to 40% of patients will progress after BCG therapy and develop invasive bladder cancer. Despite its extensive clinical use, we are only beginning to understand how BCG works. Here we review preclinical and clinical data that implicate BCG-induced Th1 and cytotoxic cellular immune responses in cancer regression. We propose that future immunotherapies should aim to augment Th1 and/or cellular responses in those that fail BCG therapy. We review clinical trials of immunotherapy in bladder cancer with a focus on the promising role of checkpoint blockade inhibitors that target the programmed cell death 1/programmed death-ligand 1 (PD-L1) axis and/or cytotoxic T lymphocyte antigen 4.

Abstract
Immunotherapy with Bacillus Calmette-Guérin (BCG) is the most efficacious treatment for high-risk bladder cancer (BC) (Ta/T1 or carcinoma in situ) to reduce the risk of recurrence. Our aim was to evaluate whether hypertension and diabetes influence the outcome of patients with noninvasive BC treated with BCG instillations.In order to collect homogeneous data, we considered as "hypertensive" only those patients who had previous diagnosed hypertension and a history of taking medical therapy with antihypertensive drugs (AHT), and as "diabetic" only those prescribed oral antidiabetics or insulin (ADT).We analyzed 343 high-risk BC patients undergoing BCG (1995-2010) with a median follow-up of 116 months (range 48-238). The distribution of various kinds of AHT and antidiabetic drugs was homogeneous, with no significant differences (p > 0.05).In both univariate and multivariate analyses, the only statistically significant parameter prognostic for recurrence after BCG treatment was AHT. Recurrence-free survival curves showed a significant correlation with AHT (p = 0.0168, hazards ratio [HR] 1.45, 95% confidence interval [CI] 1.0692-1.9619); there was no correlation (p = 0.9040) with ADT (HR 0.9750, 95% CI 0.6457-1.4721). After stratification of AHT and ADT according to drug(s) prescribed, there were no significant differences in the BC recurrence rate (p > 0.05).In this study with a very long-term follow-up, hypertension alone (evaluated by AHT) revealed the increased risk of BC recurrence after BCG treatment.Several hypotheses have been formulated to support these findings, but further prospective studies are needed to both evaluate the real influence of hypertension and identify a possible prognostic factor to be used in selecting poor-prognosis BC patients as early candidates for surgical treatment.

Abstract
OBJECTIVES To assess bacillus Calmette-Guérin maintenance treatment schedule for non-muscle invasive bladder cancer at 2 years, using one-third of the full dose and fewer instillations every 3 months or 6 months. METHODS This was a prospective, randomized, multicenter study. All patients had an intermediate- or high-risk non-muscle invasive bladder cancer. They received three weekly instillations of one-third dose bacillus Calmette-Guérin every 6 months (group I) and two weekly instillations every 3 months (group II) during 3 years. In the two schedules we assessed efficacy, tolerance, leukocyturia and prostate-specific antigen. RESULTS No significant difference was observed between the two groups for recurrence at 6, 12 or 18 months. At 2 years, tumor recurrence was observed in 10.9% and muscle invasion in 2.9% of cases. Bacillus Calmette-Guérin tolerance was comparable - the adverse events score was 0.8 in group I and 1 in group II (P = 0.242). No statistical correlation was observed between the adverse events score over 2 years, either for leukocyturia (P = 0.8891) or prostate-specific antigen level (P = 0.7155). Leukocyturia level was not significantly associated with tumor recurrence or progression. CONCLUSION One-third dose maintenance bacillus Calmette-Guérin is effective with no impact on tumor recurrence or muscle invasion. Furthermore, there seems to be no difference in tumor response or side-effects between patients receiving two or three maintenance instillations every 3 months or 6 months. In clinical practice, the use of leukocyturia or total prostate-specific antigen levels do not appear to be useful in predicting bacillus Calmette-Guérin toxicity.

Abstract
In the second section of a two-part article, the recent literature is reviewed and the management of nonmuscle-invasive transitional cell carcinoma of the bladder is discussed. Particular attention is given to the indications and timing of intravesical chemotherapy and immunotherapy and the differences in efficacy and side-effect profiles of the available agents. The indications and role of second-look transurethral resection are reviewed. Additionally, the role of bacillus Calmette-Guerin in the management of this disease in terms of definitive treatment and maintenance therapy is discussed. We also offer a review of the literature regarding therapies for bacillus Calmette-Guerin-refractory nonmuscle-invasive transitional cell carcinoma of the bladder and their current place in practice.

Abstract
OBJECTIVE To investigate whether secretion of human β-defensin 2 (HBD-2) is induced by bacillus Calmette-Guérin (BCG) and to determine whether HBD-2 affects BCG internalisation in bladder cancer cells. MATERIALS AND METHODS Reverse transcription-polymerase chain reaction analysis was used to determine whether HBD-2 mRNA increases after incubation with BCG. HBD-2 proteins in 5637 and T24 human bladder cancer cell lines were assayed by enzyme-linked immunosorbent assay. The internalisation rate was evaluated by double immunofluorescence assay and confocal microscopy to test the optimal dose of HBD-2 for BCG internalisation. We also investigated the difference in internalisation rates and cell viability between recombinant HBD-2 protein, anti-HBD-2 antibody, and HBD-2 plus anti-HBD-2 antibody pretreatments. RESULTS BCG induced HBD-2 mRNA expression and HBD-2 production dose and time-dependently in bladder cancer cells and affected BCG internalisation. Pretreatment with recombinant HBD-2 protein lowered internalisation of BCG dose-dependently. Moreover, anti-HBD-2 antibody prevented the effect of HBD-2 on BCG internalisation in bladder cancer cells. The internalisation rate of BCG pretreated with anti-HBD-2 antibody was higher than that in the control in 5637 (P < 0.01) and T24 cells (P < 0.05). The BCG internalisation rate in cells pretreated with anti-HBD-2 antibody plus recombinant HBD-2 protein was higher than that in the control in 5637 (P < 0.01) and T24 cells (P < 0.05). Mycobacterium bovis BCG decreased bladder cancer cell viability, and anti-HBD-2 antibody prevented the inhibitory role of HBD-2 on the anti-proliferative effects of M. bovis BCG in bladder cancer cells CONCLUSION Bladder cancer cells produce HBD-2 when they are infected by BCG to defend themselves against BCG internalisation, which plays an important role during the initiation and propagation of the immunotherapeutic response in bladder cancer cells.

Abstract
Intravesical Bacillus Calmette Guérin (BCG) immunotherapy is considered the standard of care for treatment of non-muscle invasive bladder cancer; however the treatment parameters were established empirically. In order to evaluate potential optimization of clinical parameters of BCG induction therapy, we constructed and queried a new mathematical model. Specifically, we assessed the impact of (1) duration between resection and the first instillation; (2) BCG dose; (3) indwelling time; and (4) treatment interval of induction therapy – using cure rate as the primary endpoint. Based on available clinical and in vitro experimental data, we constructed and parameterized a stochastic mathematical model describing the interactions between BCG, the immune system, the bladder mucosa and tumor cells. The primary endpoint of the model was the probability of tumor extinction following BCG induction therapy in patients with high risk for tumor recurrence. We theoretically demonstrate that extending the duration between the resection and the first BCG instillation negatively influences treatment outcome. Simulations of higher BCG doses and longer indwelling times both improved the probability of tumor extinction. A remarkable finding was that an inter-instillation interval two times longer than the seven-day interval used in the current standard of care would substantially improve treatment outcome. We provide insight into relevant clinical questions using a novel mathematical model of BCG immunotherapy. Our model predicts an altered regimen that may decrease side effects of treatment while improving response to therapy.

Abstract
PURPOSE Docetaxel is a safe agent for intravesical therapy. Adding monthly maintenance treatments can extend response durability. We report our cumulative experience with intravesical docetaxel in a larger cohort with extended followup. MATERIALS AND METHODS A total of 54 patients received salvage intravesical docetaxel for bacillus Calmette-Guérin refractory nonmuscle invasive bladder cancer between 2003 and 2012, including 18 treated during the original phase I trial. All patients received 6 weekly instillations of intravesical docetaxel. After the phase I trial, those with a complete response to induction treatment were offered single dose monthly maintenance treatments for a total of up to 12 months of docetaxel therapy. Recurrence was defined as positive biopsy or urine cytology. Recurrence-free, disease specific and overall survival was determined by Kaplan-Meier analysis. RESULTS Median followup was 39.1 months. Of the 54 patients 32 (59%) had a complete initial response after induction therapy, including 18 who received additional monthly maintenance treatments. Median time to recurrence in initial responders treated with vs without docetaxel maintenance was 39.3 vs 19.0 months. One and 3-year recurrence-free survival rates for the entire cohort were 40% and 25%, respectively. Of the 54 patients 17 (24%) underwent radical cystectomy at a median of 24 months of followup. Five-year disease specific and overall survival rates were 85% and 71%, respectively. CONCLUSIONS Intravesical docetaxel appears to be a promising agent with significant efficacy and durability for bacillus Calmette-Guérin refractory nonmuscle invasive bladder cancer. Adding maintenance treatments may increase the duration of recurrence-free survival.

Abstract
Most cancer patients are treated with some combination of surgery, radiation, and chemotherapy. Despite recent advances in local therapy with curative intent, chemotherapeutic treatments for metastatic disease often remain unsatisfying due to severe side effects and incomplete long-term remission. Therefore, the evaluation of novel therapeutic options is of great interest. Conventional, along with newer treatment strategies target the immune system that suppresses genitourinary (GU) malignancies. Metastatic renal cell carcinoma and non-muscle-invasive bladder caner represent the most immune-responsive types of all human cancer. This review examines the rationale and emerging evidence supporting the anticancer activity of immunotherapy, against GU malignancies.

Abstract
Mycobacterium bovis bacille Calmette-Guerin (BCG) is one of the great success stories of immunotherapy as a treatment for superficial urothelial carcinoma of the bladder. Despite clinical effectiveness in over 50% of patients, the high incidence of local side effects and presence of nonresponders has led to efforts to improve the therapy. Recent advances have suggested a role for neutrophils and TNF-related apoptosis-inducing ligand (TRAIL) in the antitumor inflammatory response. Cell wall components of mycobacteria alone, lowered doses of BCG, and combination with cytokines have been studied as ways to improve the immune response associated with BCG and/or reduce toxicity. This review will discuss the clinical use of BCG, its proposed mechanism of action, and directions of future research to improve efficacy and decrease side effects.

Abstract
OBJECTIVE To examine the incidence of recurrence and progression in patients with stage T1, grade-3 carcinoma of the bladder treated with endovesical bacillus Calmette-Guérin (BCG) after complete transurethral resection. MATERIAL AND METHODS From May 1995 to June 2002, 937 patients with superficial bladder cancer underwent transurethral resection. 46 patients (4.9%) had T1G3 tumors. All patients received endovesical BCG therapy 2-3 weeks after transurethral resection, given in 6 sessions as weekly instillations of 120 ml Pasteur strain BCG in 50 ml saline. Success was defined by normal cytology and cystoscopy, and normal bladder biopsies. Recurrent tumors were resected and a second or third cycle of therapy was given according to pathological status. Progressive tumors were managed by radical cystectomy, radiotherapy and/or chemotherapy depending on the nature of the tumor or clinical status of the patient. RESULTS During follow-up 60.7% of the patients (28 of 46) remained tumor free after only 1 BCG cycle and 73.9% (34 of 46) after the third BCG cycle, and the bladder was preserved in all. Muscle-invasive progression was noted in 10 (21.7%) patients at the end of the BCG cycles. Radical cystectomy was done in 10 patients. The tumor-free survival rate of all patients including those who underwent cystectomy is 84.8% (39 of 46) with a median follow-up of 61 (range 39-118) months. CONCLUSION Adjuvant immunotherapy with BCG after complete transurethral resection of the bladder tumor represents a highly effective treatment for bladder preservation in stage pT1, grade-3 carcinoma of the bladder. pT1G3 tumors with early high-grade recurrence after failed immunotherapy should be regarded as candidates for early radical cystectomy.

Abstract
OBJECTIVES To conduct a trial using three different doses of bacillus Calmette-Guérin (BCG) to determine whether lowering the dose of BCG could reduce toxicity without compromising its efficacy in the treatment of superficial bladder cancer. METHODS From July 2002 to June 2005, 152 patients with superficial bladder cancer entered the trial. The patients were randomized to receive three different doses of BCG: 40, 80, and 120 mg. There were no significant differences in clinical and pathologic characteristics among the three groups. Twenty-four patients could not be followed to the end of the study because of poor compliance. At completion of the study, 40 patients could be evaluated in group A (40 mg), 48 in group B (80 mg), and 40 in group C (120 mg). RESULTS After treatment patients were evaluated for a mean follow-up period of 36 months (range 18 to 52 months). No significant difference in recurrence rate (20% versus 25% versus 20% respectively; P >0.05) was observed among the groups, and no progression of the disease was seen. Significant differences were observed among groups A, B, and C in local toxicity (30% versus 41.7% versus 70%, respectively; P <0.01). Systemic toxicity was more common in group C compared with groups B and A (P <0.01). CONCLUSIONS Reduction in the dose of intravesical BCG can reduce the toxicity associated with the treatment of superficial bladder cancer without affecting the efficacy of therapy.

Abstract
From review of the currently available trial evidence, several clinical recommendations for bladder tumor management become apparent. Transurethral resection should be done, but this procedure is prone to both overestimating and underestimating staging. Restaging transurethral resection for patients with T1 tumors should, therefore, be performed. Data support the immediate postoperative instillation of a chemotherapeutic agent for patients with solitary, low-grade papillary tumors, whereas patients with multiple lesions might benefit from a more intensive adjuvant regimen. Although the use of intravesical immunotherapy for reducing tumor progression or as maintenance therapy is controversial, bacillus Calmette-Guérin has demonstrated significant benefit for tumor prophylaxis when no obvious residual disease is present. Early radical cystectomy can be beneficial and should be performed in patients with refractory T1 tumors or carcinoma in situ before progression to muscle invasion. In this Review I present an overview of the management of nonmuscle invasive bladder cancer. The most common intravesical chemotherapeutic agents are described as well as the impact of chemotherapy on the recurrence and progression of tumors. The effect of intravesical immunotherapy in bladder cancer is explored as well as the role of early cystectomy.

Abstract
OBJECTIVE The primary aim was to search for lower doses of Bacillus Calmette-Guerin (BCG) that are effective and have lower toxicity. METHODS A low dose of BCG 27 mg was compared with BCG 13.5mg, using mitomycin C (MMC) 30 mg as the third arm of comparison. A total of 430 patients with intermediate-risk superficial bladder cancer were randomised into three groups. Instillations were repeated once a week for 6 wk followed by another six instillations given once every 2 wk during 12 wk. RESULTS There was a significantly longer disease-free interval for BCG 27 mg versus MMC 30 mg (p=0.006). There were no statistically significant differences between BCG 27 mg and BCG 13.5mg (p=0.165) or between BCG 13.5mg and MMC 30 mg (p=0.183). Cox proportional hazards regression showed that disease-free interval in the multivariate analysis was significantly better for primary disease and treatment with BCG 27 mg. There were no significant differences among the three groups with regards to time to progression and cancer-specific survival time. Local and systemic toxicity were higher in both BCG treatment groups. CONCLUSIONS One third of the standard dose, BCG 27 mg, seems to be the minimum effective dose as adjuvant treatment for intermediate-risk superficial bladder cancer, being more effective than MMC 30 mg. One sixth of the standard dose, BCG 13.5mg, has the same efficacy as MMC 30 mg but it is more toxic.

Abstract
Bladder cancer is a heterogeneous disease. Non–muscle-invasive bladder cancer embraces a spectrum of tumors with varying degrees of clinical behavior. Transurethral resection remains the surgical mainstay for the treatment of non–muscle-invasive bladder cancer. In an attempt to decrease the recurrence or progression rate, intravesical chemotherapy or immunotherapy is also used. Radical cystectomy with bilateral pelvic lymph node dissection remains the gold standard for treating muscle-invasive bladder cancer. Over the last decade, the orthotopic neobladder has gained widespread popularity as the preferred mode of urinary diversion in both males and females with similar oncologic and functional outcomes. Well-designed trials with effective chemotherapy have shown a beneficial role for neoadjuvant chemotherapy.

Abstract
OBJECTIVE To report the side-effects after a reduction in the dwell-time in patients who had pronounced symptoms after intravesical bacillus Calmette-Guèrin (BCG) treatment, as side-effects such as fever, haematuria, and frequency are common and sometimes severe after BCG treatment in patients with bladder cancer. PATIENTS AND METHODS The dwell-time was reduced to < or = 30 min in 51 patients who had pronounced side-effects after the preceding BCG instillation. All patients self-reported side-effects after each instillation in a questionnaire. RESULTS After reducing the BCG dwell-time, fever, chills, dysuria and the overall time-to-recovery were significantly reduced but frequency and haematuria were not influenced. Patients with carcinoma in situ had significantly less dysuria than patients with papillary tumours. There was no difference in the treatment results between patients who had a normal dwell-time and a reduced dwell-time, determined at the first and second follow-up cystoscopy. CONCLUSION Reducing the BCG dwell-time to < or = 30 min could be an alternative to a dose reduction in patients who experience pronounced side-effects after BCG instillations. The long-term outcome after reducing dwell-time and after dose reduction has not been studied and warrants further investigation.

Abstract
Most bladder cancers present as a superficial disease, confined to the bladder mucosa or submucosal layer, without muscle invasion. Most superficial tumors have a propensity for recurrence after transurethral resection; some have a high risk for progression to muscle invasion. The treatment aim in superficial bladder cancer with intravesical therapy is three-fold: (1) eradicate existing disease, (2) prevention of recurrence, (3) prevention of tumor progression. The prognostic factors (tumor stage, grade, size, number and recurrence pattern) allow the stratification of tumors in different risk groups to plan treatment. Studies on pharmacokinetics have proved the efficacy of optimized drug delivery. Comparing resection with and without intravesical chemotherapy, a short-term reduction, approximately 15%, in tumor recurrence with chemotherapy can be obtained, but no effect on progression was proven. No agent has proved to be more effective than the others. A single instillation of chemotherapy immediately after transurethral resection has proven to be effective, but the role of maintenance therapy is controversial. Immunotherapy, in the form of Bacillus Calmette-Guerin, is generally shown to be more effective than chemotherapy, even if the results in comparison to mitomycin C do not result conclusive. Several new approaches are being explored to improve the efficacy of this therapy.

Abstract
The following steps are practical in the treatment of intermediate-to-high risk patients with superficial bladder cancer: Resect all visible tumor at the time of first TUR of bladder tumor. Strongly consider re-resection, especially for high-risk, large, multifocal, stage T1 tumors. Apply one dose of cytotoxic chemotherapy perioperatively within 6 hours of TUR (ideally immediately). Once histopathology is available, consider intravesical induction chemotherapy for intermediate-risk patients and BCG for intermediate- or high-risk patients and those having failed prior chemotherapy. At least 1 year of maintenance therapy should be planned for all intermediate-to-high risk BCG-treated patients. Chemotherapy maintenance may be useful if perioperative chemotherapy was omitted. For patients failing standard therapy, a thorough discussion of the risks (including progression and metastasis) and expected benefits should take place before the initiation of salvage therapy. The radical cystectomy option should be openly entertained. Consider BCG plus interferon or gemcitabine-based salvage programs if appropriate. Explore clinical trial options. Contact urologic cancer experts for guidance and advice.

Abstract
AIM To compare bacillus Calmette-Guerin (BCG) with epirubicin in adjuvant therapy of superficial bladder transitional cell carcinoma, with respect to recurrence, progression and survival. Prognostic factors are also evaluated. METHODS Between October 1991 and September 1999, all patients harboring superficial bladder cancers (Ta or T1) with any of the relevant criteria (stage>a, grade>1, size>1 cm, multiple or recurrent tumors), after complete transurethral resection were randomized to receive either 81 mg Connaught strain BCG or 50 mg epirubicin. Patients with recurrences were eligible to crossover, even repeatedly, until progression. Recurrence, progression and survival were analyzed in relation to initial treatment, patient characteristics and tumor characteristics. RESULTS There were 209 patients included in the study, 149 men and 60 women. The mean age was 69.9 years (range, 24-92). The BCG group consisted of 102 patients and the epirubicin group contained 107 patients. Final analysis was made at a median follow up of 23, 47 and 61 months for recurrence, progression and survival, respectively. The 10-year Kaplan-Meier estimates for recurrence-free, progression-free and disease-specific survival were 61%, 78% and 80%, respectively, for the BCG group. The corresponding figures were 32%, 74% and 92%, respectively, for the epirubicin group. Time to recurrence differed significantly between two treatment groups (P=0.0004). Multiplicity increased the risk of recurrence, while grading influenced recurrence, progression and disease specific survival. CONCLUSIONS Bacillus Calmette-Guerin prolonged time to recurrence when compared with epirubicin. Grading was shown to be a universal prognostic factor for recurrence, progression and disease specific survival.

Abstract
BACKGROUND We examined the incidence and severity of adverse drug reactions following intravesical bacillus Calmette-Guerin (BCG) instillation for superficial bladder cancer including carcinoma in situ. We investigated the relationship between adverse drug reactions and patient background to clarify risk factors for the development of adverse drug reactions. METHODS A total of 123 patients who underwent intravesical BCG instillation for treatment and prophylaxis between April 1997 and June 2000 were included in this study. Adverse drug reactions were divided into local and systemic categories and the severity of reactions was classified according to the presence or absence of postponement or discontinuation of instillation, with or without treatment for the reaction itself. RESULTS Of 123 patients, 95.9% showed adverse drug effects and 50.4% needed some sort of treatment. Discontinuation of instillation due to adverse drug reactions was observed in nine patients. Regarding the necessity of treatment for adverse drug effects, the purpose of instillation and BCG dose were independent significant factors on multivariate analysis. CONCLUSION Although there was a high rate of adverse drug reactions after intravesical BCG instillation, the rate of discontinuation of instillation was not high and serious adverse reactions were rare. The scale of the present study was small, but these results suggest that BCG instillation was well tolerated. When instillation is being performed for the purpose of treatment, and the BCG dose is 80 mg, greater attention might be needed to monitor for the development of adverse drug effects.

Abstract
AIM We studied the clinical characteristics of bladder cancer, with special attention to the clinical and pathological variables that affect tumor stage, relapse and efficacy of intravesical therapy. METHODS We reviewed the medical records of 152 patients of the Saiseikai Central Hospital who had been diagnosed as having bladder cancer between 1981 and 2001. RESULTS The age of the patients ranged from 24 to 88 years, with a median of 63.5 years. The median follow up was 52.4 months (range, 0.5-259.5 months). There was no difference in the incidence of gross hematuria as a presenting symptom among the patients with invasive cancer, superficial cancer and carcinoma in situ (CIS). However, the incidence of urinary frequency and painful urination did differ significantly between patients. Although patients with invasive cancer had a longer time to hospital visit than those with superficial cancer, this time difference was not statistically significant. Presence of proteinuria, multifocality and intravesical bacille Calmette-Guerin (BCG) therapy were the significant predictors of relapse after transurethral resection (TUR). Presence of proteinuria was shown to adversely affect the efficacy of intravesical BCG therapy. In the BCG-treated group, 3-year relapse-free survival was 78.4% for patients without proteinuria and 40.0% for those with proteinuria; this difference was statistically significant (P = 0.0277). CONCLUSIONS Time to hospital visit did not influence the pathological stage of cancer in patients included in the present study. Presence of proteinuria, multifocality and BCG therapy were the significant predictors of relapse after TUR. Presence of proteinuria was shown to adversely affect the efficacy of intravesical BCG therapy. Proteinuria might be helpful in predicting tumor relapse and efficacy of intravesical BCG therapy in clinical settings, along with other markers.

Abstract
BACKGROUND Bacillus Calmette-Guerin (BCG) at low doses has long been employed as prophylactic and therapeutic treatment for superficial cancer of the urinary bladder, aiming at reducing toxicity while maintaining efficacy. A retrospective review was reported, together with a review of the literature with respect to a low dose BCG regimen. METHODS Forty-five consecutive patients with superficial bladder cancer (Ta or T1) with one or more of the appropriate criteria (grade above 1, stage above a, size >1 cm, multiple or recurrent), after complete transurethral resection, received 27 mg Connaught strain BCG weekly for 6 weeks. There was no maintenance therapy. Patients were evaluated with urine cytology and cystoscopy. Recurrence, progression and death were analysed. RESULTS With a median follow up of 14 (range 3-61) months, 24 (53%) of the 45 patients responded to one course of 6 weekly BCG without recurrence. A further group of 13 (29%) patients responded to a second course of BCG on recurrence. Disease progressed in one (2.2%) patient. Two (4.4%) patients died of an unrelated condition. There was no disease specific mortality. Side-effects were common but well tolerated, with only two (4.4%) cases of treatment interruption. CONCLUSIONS Low dose BCG could be an alternative option of adjuvant therapy for superficial bladder cancer with acceptable toxicity and good compliance.

Abstract
Superficial transitional cell carcinoma (STCC) of the bladder is usually managed with intravesical bacille Calmette-Guerin. Recombinant human interleukin-12 (rhIL-12) is a heterodimeric cytokine that induces T-cell and natural killer cell proliferation/activation and production of IFNgamma. It has demonstrated preclinical in vivo bladder antitumor activity and no systemic toxicity. This phase 1 study evaluated intravesical rhIL-12 administration in patients with STCC (Tis, Ta, or T1) who had failed at least one prior intravesical therapy or had at least two recurrences of low-grade tumors. Eligible patients had adequate hematologic, renal, and hepatic function and Karnofsky performance status at least 70%. Cohorts of three patients received 5, 20, 50, 100, and 200 microg rhIL-12 (treated n = 15). Each patient received intravesical rhIL-12 weekly for 6 weeks, with a 2-hour bladder dwell. No patient experienced moderate, severe, or life-threatening systemic toxicity. Treatment-related adverse events included dysuria, urinary frequency, urinary urgency, asthenia, pain, hematuria, bladder spasms, and chills. Specific AE incidences were not dose-related. Among 12 patients without visible pretreatment lesions, 7 remained disease-free and 5 experienced recurrence of STCC within the 4-week follow-up period. Three patients with pretreatment Tis or Ta/T1 lesions had persistent disease at posttreatment follow-up. No patients with persistent tumor manifested antitumor response to rhIL-12. Two-hour dwell urine samples and 24- to 30-hour postdose serum samples showed negligible induction of IFNgamma. In summary, intravesical rhIL-12 was well tolerated by patients with recurrent STCC but showed no clinically relevant evidence of antitumor or immunologic effects.

Abstract
The second part of this review examines the use of recombinant interferon-alpha (rIFNalpha) in the following solid tumours: superficial bladder cancer, Kaposi's sarcoma, head and neck cancer, gastrointestinal cancers, lung cancer, mesothelioma and ovarian, breast and cervical malignancies. In superficial bladder cancer, intravesical rIFNalpha has a promising role as second-line therapy in patients resistant or intolerant to intravesical bacille Calmette-Guérin (BCG). In HIV-associated Kaposi's sarcoma, rIFNalpha is active as monotherapy and in combination with antiretroviral agents, especially in patients with CD4 counts >200/mm(3), no prior opportunistic infections and nonvisceral disease. rIFNalpha has shown encouraging results when used in combination with retinoids in the chemoprevention of head and neck squamous cell cancers. It is effective in the chemoprevention of hepatocellular cancer in hepatitis C-seropositive patients. In neuroendocrine tumours, including carcinoid tumour, low-dosage (</=3 MU) or intermediate-dosage (5 to 10 MU) rIFNalpha is indicated as second-line treatment, either with octreotide or alone in patients resistant to somatostatin analogues. Intracavitary IFNalpha may be useful in malignant pleural effusions from mesothelioma. Similarly, intraperitoneal IFNalpha may have a role in the treatment of minimal residual disease in ovarian cancer. In breast cancer, the only possible role for IFNalpha appears to be intralesional administration for resistant disease. IFNalpha may have a role as a radiosensitising agent for the treatment of cervical cancer; however, this requires confirmation in randomised trials. On the basis of current evidence, the routine use of rIFNalpha is not recommended in the therapy of head and neck squamous cell cancers, upper gastrointestinal tract, colorectal and lung cancers, or mesothelioma. Pegylated IFNalpha (peginterferon-alpha) is an exciting development that offers theoretical advantages of increased efficacy, reduced toxicity and improved compliance. Further data from randomised studies in solid tumours are needed where rIFNalpha has activity, such as neuroendocrine tumours, minimal residual disease in ovarian cancer, and cervical cancer. A better understanding of the biological mechanisms that determine response to rIFNalpha is needed. Studies of IFNalpha-stimulated gene expression, which are now feasible, should help to identify molecular predictors of response and allow us to target therapy more selectively to patients with solid tumours responsive to IFNalpha.

Abstract
BACKGROUND Intravesical instillation of bacillus Calmette-Guérin (BCG) is the most efficient strategy for prophylaxis of superficial bladder cancer recurrence. Adverse effects of BCG are major obstacles, but the reduction of BCG dose could minimize these effects. The efficacy and adverse effects of half-dose (40 mg) BCG, Tokyo 172 strain, were prospectively evaluated. METHODS A total of 93 patients with superficial bladder cancer (pTa or pT1) were sequentially assigned to receive either 40 or 80 mg of BCG after transurethral resection. BCG was administered weekly for 6 weeks postoperatively. Eighty patients observed longer than 12 months after BCG therapy (41, 40 mg group; 39, 80 mg group) were analyzed. RESULTS BCG therapy course was completed in 71 patients. Tumor recurrence was recognized in 11 of 40 patients in the 40 mg group and in 5 of 31 patients in the 80 mg group. There was no significant difference in tumor recurrence rate between the two groups (P = 0.547). BCG therapy was withdrawn in 1 patient in the 40 mg group and in 8 patients in the 80 mg-group because of BCG-related adverse effects. The morbidity of BCG-related toxicity was significantly higher in the 80 mg group. CONCLUSION Half-dose of BCG Tokyo 172 strain had a similar efficacy and its toxicity was significantly lower compared to the standard dose. Thus, half-dose of this strain might be suitable, at least for initial BCG therapy, for the prophylaxis of bladder cancer recurrence. Further study would be necessary to clarify the efficacy of low-dose instillation in high-risk patients.

Abstract
BACKGROUND The objective of this study was to retrospectively investigate the effectiveness of transurethral resection of bladder tumor (TURBT) and intravesical instillation therapy for stage T1, grade 3 (T1G3) transitional cell carcinoma (TCC) of the urinary bladder. METHODS Between January 1995 and December 1997, 97 patients with T1G3 TCC of the urinary bladder were treated by TURBT and adjuvant intravesical instillation with bacillus Calmette-Guérin (BCG) or other anticancer agents. The recurrence-free survival rates were evaluated according to several clinicopathological factors. The cases that progressed to muscle invasive disease were also analysed. RESULTS In this series, the median follow-up period was 25 months (range, 5- 41) after the initial TURBT. Intravesical recurrence was noted in 44 patients (45%), and the 1, 2, and 3 year recurrence-free survival rates were 72%, 58%, and 42%, respectively. Multivariate analyses revealed that the risk of intravesical recurrence was significantly higher for patients who did not receive BCG therapy, irrespective of age, gender, tumor size, multiplicity, pathological stage, concomitant carcinoma in situ, and lymphovascular involvement. Moreover, after a median of 10 months, disease progression occurred in seven patients (7%), of which only one patient was treated by BCG therapy after initial TURBT. CONCLUSION These findings suggest that intravesical instillation with BCG combined with TURBT is an effective conservative treatment for T1G3 TCC of the bladder. Patients with negative prognostic factors should be treated by BCG rather than other anticancer agents after TURBT.
