Abstract
INTRODUCTION To assess gender-specific differences in recurrence-free survival (RFS), progression-free survival (PFS), cancer-specific survival (CSS), and overall survival (OS) among patients with intermediate or high-risk non-muscle-invasive bladder cancer (NMIBC) receiving BCG was the primary aim of this systematic review and meta-analysis. METHODS In July 2023, we performed a literature search using MEDLINE, Embase, and the Cochrane Library. This study was prospectively registered at PROSPERO (CRD 2023443269). The detailed review protocol is accessible via CRD. RESULTS The systematic literature search identified 6,723 studies, of which 38 fulfilled the inclusion criteria. Random-effect meta-analysis for RFS, based on data from 24 studies, revealed no statistically significant gender-specific difference (HR comparing males to females = 0.9618, 95% CI: 0.8408-1.1003, p = 0.5707). Similarly, for PFS, incorporating data from 14 studies, no statistically significant difference (HR = 0.9540, 95% CI: 0.7709-1.1805, p = 0.6648), for CSS, analysis of data from three studies yielded no statistically significant difference (HR = 0.9228, 95% CI: 0.6196-1.3743, p = 0.6925), and for OS, based on data from two studies, no statistically significant difference was observed (HR = 1.1436, 95% CI: 0.5092-2.5684, p = 0.7452). The risk of bias assessment indicated an overall moderate to high risk of bias. CONCLUSION The findings indicate no association between gender and oncologic outcomes following BCG.

Abstract
PURPOSE To investigate the effectiveness and safety of device-assisted intravesical chemotherapy compared to Bacillus Calmette-Guerin (BCG) in the treatment of patients with intermediate- and high-risk non-muscle-invasive bladder cancer (NMIBC). METHODS In February 2023, a systematic search was conducted on the PubMed, Cochrane, and Embase databases. Following the PRISMA guidelines, a systematic review and meta-analysis of the primary outcomes of interest were performed. The review was prospectively registered on PROSPERO under the registration number CRD42023398559. RESULTS A total of 10 studies involving 1160 patients were included. The results of the meta-analysis showed that compared to BCG, device-assisted chemotherapy had a lower recurrence rate (OR: 0.63, 95% CI: 0.48-0.84, p = 0.001), longer recurrence-free survival (OR: 0.64, 95% CI: 0.47-0.88, p = 0.006), and lower incidence of fever (OR: 0.18, 95% CI: 0.08-0.44, p = 0.0002). However, no significant differences were observed between the two groups in terms of progression, overall survival, progression-free survival, disease-free survival, overall adverse events, serious adverse events, hematuria, allergy, and general discomfort. Subgroup analysis revealed that neither chemohyperthermia (CHT) nor electromotive drug administration (EMDA) showed statistically significant differences in oncological outcomes compared to BCG. Regarding adverse events, both CHT and EMDA groups showed lower rates of fever compared to the BCG group (OR: 0.26, 95% CI: 0.10-0.67, p = 0.005, and OR: 0.14, 95% CI: 0.05-0.37, p < 0.0001, respectively). No significant differences were observed in the remaining adverse events between either the CHT or EMDA group and the BCG group. CONCLUSION Device-assisted intravesical chemotherapy appears to be a safe and viable alternative to BCG for patients with intermediate and high-risk NMIBC, showing comparable oncological outcomes and adverse events.

Abstract
The COVID-19 disease, caused by SARS-CoV-2 virus, has been one of the worst pandemics ever to hit the human mankind. Undoubtedly the start of the second wave of COVID-19 has literally ripped apart the hearts of millions of people. Cancer patients have been left of the beaten track to their fate, with no access to treatments. Intravesical BCG instillation is the standard of care for patients with non-muscle invasive bladder cancer (NMIBC). Several patients were in the middle of their treatment regimen when this pandemic struck. As slowly the word is recuperating from concussion effect of this pandemic and routine health services are being restored, uro-oncologist will face a unique scenario with respect to intravesical BCG therapy i.e., whether to restart the course of BCG therapy or to continue course from where it was interrupted. There are no studies in literature to directly answer this peculiar question and to resolve this dilemma. So, we in this review article propose to explore the literature for the most appropriate therapeutic regimen for these patients with interruption of intravesical BCG therapy. We plan to divide the patients with interruption to BCG therapy into the following three groups:Group 1: Patients who had interruption during the induction period.Group 2: Patients who completed the induction course but maintenance course could not be started.Group 3: Patients who had interruption during maintenance phase of BCG therapy. We will compile the recent recommendations by NCCN, AUA, and EAU for the administration of intravesical BCG in non-muscle invasive bladder cancer. We herein want to review the literature to propose the most appropriate strategy, its safety profile for these subsets of patients.

[PMID: 37046598 PMCID: PMC10093360 DOI: 10.3390/cancers15071937] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2023] [Revised: 03/19/2023] [Accepted: 03/20/2023] [Indexed: 04/14/2023] Open
Abstract
BACKGROUND In an era of Bacillus of Calmette-Guérin (BCG) shortages, the comparative efficacy from different adjuvant intravesical BCG strains in non-muscle invasive bladder cancer (NMIBC) has not been clearly elucidated. We aim to compare, through a systematic review and meta-analysis, the cumulative BC recurrence rates and the best efficacy profile of worldwide available BCG strains over the last forty years. METHODS PubMed, Scopus, Web of Science, Embase, and Cochrane databases were searched from 1982 up to 2022. A meta-analysis of pooled BC recurrence rates was stratified for studies with ≤3-y vs. >3-y recurrence-free survival (RFS) endpoints and the strain of BCG. Sensitivity analysis, sub-group analysis, and meta-regression were implemented to investigate the contribution of moderators to heterogeneity. A random-effect network meta-analysis was performed to compare BCG strains on a multi-treatment level. RESULTS In total, n = 62 series with n = 15,412 patients in n = 100 study arms and n = 10 different BCG strains were reviewed. BCG Tokyo 172 exhibited the lowest pooled BC recurrence rate among studies with ≤3-y RFS (0.22 (95%CI 0.16-0.28). No clinically relevant difference was noted among strains at >3-y RFS outcomes. Sub-group and meta-regression analyses highlighted the influence of NMIBC risk-group classification and previous intravesical treated categories. Out of the n = 11 studies with n = 7 BCG strains included in the network, BCG RIVM, Tice, and Tokyo 172 presented with the best-predicted probability for efficacy, yet no single strain was significantly superior to another in preventing BC recurrence risk. CONCLUSION We did not identify a BCG stain providing a clinically significant lower BC recurrence rate. While these findings might discourage investment in future head-to-head randomized comparison, we were, however, able to highlight some potential enhanced benefits from the genetically different BCG RIVM, Tice, and Tokyo 172. This evidence would support the use of such strains for future BCG trials in NMIBCs.

Effects of intravesical BCG maintenance therapy duration on recurrence rate in high-risk non-muscle invasive bladder cancer (NMIBC): Systematic review and network meta-analysis according to EAU COVID-19 recommendations. PLoS One 2022; 17:e0273733. [PMID: 36074771 PMCID: PMC9455878 DOI: 10.1371/journal.pone.0273733] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2022] [Accepted: 08/12/2022] [Indexed: 12/01/2022] Open
Abstract
Purpose During the coronavirus disease 2019 (COVID-19) pandemic, the European Association of Urology (EAU) recommended that courses of intravesical bacillus Calmette-Guérin (BCG) therapy lasting more than 1 year could be safely terminated for patients with high-risk non-muscle-invasive bladder cancer (NMIBC). Thus, we conducted a systematic review and network meta-analysis according to EAU’s COVID-19 recommendations. Materials and methods A systematic review was performed following the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. We conducted a network meta-analysis of recurrence rate in patients with NMIBC receiving induction therapy (M0) and those receiving maintenance therapy lasting 1 year (M1) and more than 1 year (M2). Results Nineteen studies of 3,957 patients were included for the network meta-analysis. In a node-split forest plot using Bayesian Markov Chain Monte Carlo (MCMC) modeling, there were no differences between the M1 and M2 groups in recurrence rate [odds ratio (OR) 0.95 (0.73–1.2)]. However, recurrence rate in the M0 group was higher than that in the M1 [OR 1.9 (1.5–2.5)] and M2 [OR 2.0 (1.7–2.4)] groups. P-score tests using frequentist inference to rank the treatments in the network demonstrated that the therapy used in the M2 group (P-score 0.8701) was superior to that used in the M1 (P-score 0.6299) and M0 groups (P-score 0). In rank-probability tests using MCMC modeling, the M2 group showed the highest rank, followed by the M1 and M0 groups. Conclusion In the network meta-analysis, there were no differences between those receiving BCG maintenance therapies in terms of recurrence rate. In the rank tests, therapy lasting more than 1-year appears to be most effective. During the COVID-19 pandemic, 1-year maintenance therapy can be used, but after the COVID-19 pandemic, therapy lasting more than 1-year could be beneficial.

Single course of intravesical Bacillus Calmette-Guerin versus single course with maintenance therapy in the management of nonmuscle invasive bladder cancer: A prospective randomized study. Urol Ann 2020; 12:360-365. [PMID: 33776333 PMCID: PMC7992517 DOI: 10.4103/ua.ua_137_19] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2019] [Accepted: 12/26/2019] [Indexed: 12/03/2022] Open
Abstract
Objective: The objective of the study was to compare maintenance versus single course of intravesical Bacillus Calmette–Guerin (BCG) in the management of high-risk nonmuscle invasive bladder cancer (NMIBC) regarding recurrence, progression, survival, and complications. Patients and Methods: After transurethral resection of bladder tumor (TURBT), Group I patients (33) received weekly doses of 90 mg of live attenuated Pasteur strain of BCG. The course was started 14 days after the second TURBT for 6 consecutive weeks. In Group II: 35 patients, the induction schedule was followed by 3 weekly instillations at months 3, 6, and 12 as a maintenance course. Recurrence, progression rates, survival, and toxicity were assessed in both the groups. Results: Patients with induction therapy alone had significantly higher recurrence rate than those received maintenance therapy (55.6% vs. 19.2%, P = 0.01). The 5-year recurrence-free survival rate was 41% and 78% in both the groups, respectively. There was no significant difference regarding the progression rate for both the groups. The mean 5-year progression-free time was comparable between the two groups. The 5-year progression-free survival was 69.8% for patients who underwent induction therapy alone compared to 70.7% for maintenance therapy. Overall local adverse events were significantly higher in patients who underwent maintenance treatment protocol. Statistical Analysis Used: SPSS package version 20 and Kaplan–Meier curves were used to evaluate the survival rate. Conclusions: Maintenance doses of BCG significantly decrease and delay the recurrence of high-risk NMIBC. However, there is no significant favor as regards tumor progression. Maintenance doses of BCG are significantly associated with a higher incidence of local adverse effects than induction doses alone.

Abstract
INTRODUCTION Bladder cancer is the most common malignancy of the urinary tract, and recurrence following transurethral resection poses the biggest challenge. Intravesical Bacillus Calmette-Guerin (BCG) maintenance with the Southwest Oncology Group (SWOG) protocol remains the gold standard but with poor patient compliance. MATERIALS AND METHODS The present study aims to compare the SWOG maintenance protocol with a monthly maintenance protocol comprising 12 monthly doses of intravesical BCG. Patients are included in the study only if induction BCG is completed and cystoscopy at 3 months is negative. All patients receive 80 mg BCG in each dose with strict cystoscopic surveillance every 3 months. RESULTS Patient demographics and tumor characteristics were similar in the two groups. There were no statistically significant differences in outcome in terms of recurrence, progression, and adverse reactions in both the groups. Although a larger number of patients in the SWOG maintenance group were lost to follow-up, the difference was not statistically significant proportions. CONCLUSION From this study, we can conclude that monthly maintenance BCG for 1 year is comparable in terms of outcome with SWOG protocol maintenance BCG. A greater percentage of patients in the monthly maintenance protocol completed the treatment as planned.

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
Approximately 70% of newly diagnosed bladder tumors are non-muscle invasive bladder cancer (NMIBC). NMIBC accounts for approximately 80% of total bladder cancer cases. Bacillus Calmette-Guérin (BCG) instillation and maintenance is considered as the standard adjuvant treatment for superficial bladder cancer. A number of randomized studies have focused on the benefit of maintenance therapy following initial BCG induction. To provide further insights into the effect of intravesical instillation on recurrence in patients with NMIBC, we analyzed this relationship by conducting an updated detailed meta-analysis. Evidence suggested that adjuvant intravesical BCG with maintenance treatment is significantly effective for the prophylaxis of tumor recurrence in patients with NMIBC.

Abstract
Background To explore the necessity of maintenance, efficacy of low-dose and superiority of various combination therapies of Bacillus Calmette-Guérin (BCG) in treatment of superficial bladder cancer (BCa). Methods Comprehensive searches of electronic databases (PubMed, Embase, and the Cochrane Library) were performed, then a systematic review and cumulative meta-analysis of 21 randomized controlled trials (RCTs) and 9 retrospective comparative studies were carried out according to predefined inclusion criteria. Results Significantly better recurrence-free survivals (RFS) were observed respectively in patients who received BCG maintenance, standard-dose and BCG plus epirubicin therapy comparing to those received induction, low-dose and BCG alone. BCG maintenance therapy was also associated with significantly better progression-free survival (PFS), but there were more incidences of adverse events. Pooled results showed no remarkable advantage of BCG combined with Mitomycin C or with interferon α-2b in improving oncologic outcomes. Sensitivity-analyses stratified by study-design and tumor stage led to very similar overall results and often to a decrease of the between-study heterogeneity. Our data confirmed that non-RCT only affected strength rather than direction of the overall results. Conclusions All patients with superficial BCa should be encouraged to accept BCG maintenance therapy with standard-dose if well tolerated. Patients can benefit from BCG combined with epirubicin but not from BCG combined with Mitomycin C or interferon α-2b.
