Assessment of Therapeutic Benefit and Option Strategy on Intravesical Instillation for Preventing Bladder Cancer Recurrence after Radical Nephroureterectomy in Patients with Upper Urinary Tract Urothelial Carcinoma. JOURNAL OF ONCOLOGY 2022; 2022:1755368. [PMID: 35677889 PMCID: PMC9170511 DOI: 10.1155/2022/1755368] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/08/2022] [Revised: 04/26/2022] [Accepted: 04/30/2022] [Indexed: 11/29/2022]
Abstract
Objective Upper urinary tract urothelial carcinoma (UUT-UC) is a very aggressive disease, characterized by 22%–50% of patients suffering from subsequent bladder recurrence after radical nephroureterectomy (RNU). Although the therapy of intravesical instillation is reported to be effective in preventing bladder recurrence, no study had been reported in Northeast China. The findings relating to the clinical effectiveness of intravesical instillation after RNU are somewhat controversial, and the best efficacy and least adverse effects of instillation drugs have not been widely accepted. Here, we aimed at evaluating the efficacy of intravesical instillation for the prevention intravesical recurrence systematically. Methods In this retrospective cohort study, from October 2006 to September 2017, 158 UUT-UC patients underwent RNU were divided into 4 groups: epirubicin (EPB) instillation group, hydroxycamptothecin (HCPT) instillation group, bacillus Calmette–Guerin (BCG) instillation group, and noninstillation group. Cox univariate and multivariate analyses were employed to identify the risk factors for intravesical recurrence-free survival (IVRFS). The nomogram model was also applied to predict patient outcomes. Subsequently, to evaluate the clinical significance of intravesical instillation comprehensively, several databases including PubMed, Ovid, and Embase were searched and data from published studies with our results were combined by direct meta-analysis. Moreover, a network meta-analysis comparing instillation therapies was conducted to evaluate the clinical efficacy of different instillation drugs. Results In our retrospective cohort study, the Kaplan–Meier survival curve demonstrated noninstillation groups were associated with worsened IVRFS. Meanwhile, multivariate analysis indicated that intravesical instillation was independent protective factors for IVRFS (hazard ratio [HR] = 0.731). Moreover, calibration plots, receiver operating characteristic (ROC) curves, area under the curve (AUC) values, and the C-index showed the priority of nomogram's predictive accuracy. Next, direct meta-analysis including 19 studies showed that intravesical instillation could prevent the recurrence of bladder cancer with a pooled risk ratio (RR) estimate of 0.53. Subgroup analysis by study type, year of intravesical recurrence, first instillation time, and instillation times also confirmed the robustness of the results. Moreover, intraoperative instillation was associated with a decrease in the risk of bladder recurrence compared with postoperative instillation. Then, a network meta-analysis including 7 studies indicated that pirarubicin (THP) (surface under the cumulative ranking curve [SUCRA] = 89.2%) is the most effective therapy to reduce the risk of bladder recurrence, followed by BCG (SUCRA = 83.5%), mitomycin C (MMC) (SUCRA = 53.6%), EPB (SUCRA = 52.6%), and HCPT (SUCRA = 5.1%) after the analysis of the value ranking. Conclusions A maintenance schedule of intravesical instillation prevents the recurrence of bladder cancer after RNU in UUT-UC patients effectively. Large, prospective trials are needed to further confirm its value. Compared with other chemotherapy regimens, THP may be a promising drug with favorable efficacy to prevent bladder recurrence. As included studies had moderate risk of bias, the results of network meta-analysis should be applied with caution.

Abstract
OBJECTIVE The aim of this study was to investigate cases with ocular complications associated with intravesical BCG therapy in terms of clinical features, demographic features and type of ocular involvement. METHODS PubMed database was scanned for relevant publications using the keywords. Thirty-seven publications and 147 reported cases were identified related to the development of ocular complications due to intravesical BCG treatment. RESULTS As a result of the analysis performed according to eye involvement, there were 17 cases of conjunctivitis, 7 uveitis, and 5 endophthalmitis. Only 27 (18.3%) cases were of primary ocular involvement and Reiter's syndrome was present in 120 (81.6%) of all cases. CONCLUSIONS Most of the side-effects of BCG therapy are minor and of short duration. Although rare, it has been reported that potentially serious ocular complications can develop after treatment. Physicians must keep these facts in mind and be alert to the development of ocular symptoms following BCG therapy.

Abstract
The authors present the case of a female patient with a tumor of segment VII of the liver, which was postoperatively identified as a tuberculous granuloma. The patient was admitted for elective surgery for a liver tumor, which had been diagnosed a few months before. Computed tomography and nuclear magnetic resonance were performed, based on which focal nodular hyperplasia was suspected. Thirteen years prior to admission the patient had undergone a transurethral resection of superficial bladder carcinoma, followed by adjuvant intravesical Bacillus Calmette-Guérin (BCG-therapy). Upon surgery, segment VII of the liver was resected; postoperative course was uneventful. After the identification of granuloma, the patient was referred to a phthysiatric clinic for further diagnostics and treatment. The authors have deemed this case worthy of reporting primarily due to the exceptionally long period between the completion of BCG therapy and the onset of hepatic tumor.

Abstract
BACKGROUND Intravesical instillation of Bacillus Calmette-Guérin (BCG) is an efficient immunotherapy for superficial bladder cancer. BCG infection represents a major yet uncommon adverse event that occurs in 5-10% of the patients treated with BCG instillations, though the pathogenesis of this entity is not clear. METHODS We report two cases of patients presented at our institution with BCG infection after instillation: one with microbiological BCG isolate and another without, and review all the medical records of patients instilled with BCG in our institution from 1996 until 2012, comparing patients with probable and proven BCG infection. RESULTS During the study period, a total of 786 patients received BCG intravesical instillations. Of them, 31 (4%) patients had to suspend treatment because of adverse events and, specifically, 11 (1.3%) patients had to interrupt treatment because of suspected BCG infection. The incidence of BCG infection during our study period was 0.87 episodes per 1,000 instilled patients/year and 140 cases per 10,000 instilled patients. Of the 11 patients with suspected BCG infection, 7 (64%) had a probable BCG infection, while 4 (36%) patients had a proven BCG infection. All patients with a proven infection had a previous underlying condition, compared to a high proportion of patients with probable infection (57%) that did not present with underlying diseases. Common findings between both groups of patients were abnormal imaging studies and laboratory tests. Regarding treatment, 8 (73%) of the 11 patients with BCG infection received at least two first line drugs active against M. bovis (isoniazid, rifampicin or ethambutol), four patients (36%) received steroids as part of the treatment and curation was obtained in 10 (91%) patients, while 1 patient with a proven infection had a death related to BCG infection. CONCLUSIONS We can conclude that BCG infection after intravesical instillations has a low incidence in our institution. Patients with previous underlying conditions seem to have more proven infections. A high proportion of patients do not yield positive microbiological tests; in those cases the diagnosis relies in clinical, radiological and laboratory findings. Treatment for BCG infection should include at least two active drugs against M. bovis and coadjuvant steroid treatment for systemic BCG infections.

Abstract
Intravesical instillation of Bacillus Calmette-Guérin (BCG) is the treatment of choice for superficial bladder carcinoma. We report a case of disseminated BCG infection in an early stage bladder cancer patient that initially presented with hepatitis followed by pneumonitis and sepsis. A complete clinical response was achieved in 14 days with anti-mycobacterial therapy and prednisolone. Disseminated BCG is a rare treatment complication and is likely a combination of direct infection and hypersensitivity.

Abstract
The authors present an unusual case of a 51-year-old man who developed relatively mild non-specific symptoms following intravesical BCG instillation for superficial transitional cell carcinoma of the bladder, with radiological investigations demonstrating typical features of miliary tuberculosis (TB). Transbronchial biopsy showed small foci of poorly formed granuloma suggestive of Mycobacterium infection. The patient's respiratory symptoms only became apparent 7 days after discharge having had 4 weeks of unremarkable inpatient stay where he remained clinically well. Prompt anti-TB treatment resulted in a remarkable improvement in his symptoms and radiological appearance, supporting the diagnosis of disseminated Mycobacterium bovis infection. This case highlights the importance of recognising miliary M bovis as a potential complication in patients receiving BCG immunotherapy, and that the disease course can be subclinical with delayed onset of symptoms.

Abstract
Intravesical administration of BCG is a relatively simple procedure used successfully in the treatment of superficial transitional cell carcinoma of the urinary bladder. It is usually well tolerated with few major side effects. The authors report the case of an 80-year-old man who presented with sepsis, jaundice, hepatic and pulmonary failure 10 days after his last BCG instillation therapy, that was attributed to concurrent granulomatous hepatitis and pneumonitis due to Mycobacterium bovis dissemination. In rare instances severe life-threatening complications occur in relation with BCG instillation immunotherapy that may involve multiple organs and have different presentations and require a high index of suspicion and clinical awareness in a wide range of medical specialties.

Abstract
OBJECTIVE The aim of the study was to investigate the factor of adverse reactions related to compliance with Mycobacterium bovis bacillus Calmette-Guérin maintenance therapy in patients with high-risk non-muscle-invasive bladder cancer. METHODS This study was a post hoc analysis using the database of a randomized controlled trial that examined the efficacy of bacillus Calmette-Guérin (Connaught strain) maintenance therapy. Among the 42 patients assigned to the bacillus Calmette-Guérin maintenance therapy group, six patients dropped out or withdrew consent before the bacillus Calmette-Guérin maintenance therapy. The adverse reactions and clinical backgrounds of the remaining 36 patients who underwent bacillus Calmette-Guérin maintenance therapy were compared between the two groups: the patients who completed the bacillus Calmette-Guérin maintenance therapy (the Completed group), and those who discontinued the bacillus Calmette-Guérin maintenance therapy (the Discontinued group). RESULTS Of the 36 patients who underwent bacillus Calmette-Guérin maintenance therapy, 15 (41.7%) were in the Completed group and 21 (58.3%) were in the Discontinued group. Local adverse reactions (≥G2) were observed during maintenance therapy in 86.7% of the Completed group and 95.2% of the Discontinued group. As for adverse reactions during the induction therapy (bacillus Calmette-Guérin induction therapy), the frequencies of gross hematuria and systemic adverse reactions (any grade) tended to be higher in the Discontinued group than in the Completed group, although not significantly so. In the Cochran-Armitage trend test, the linear T trend (i.e. the trend in the risk of an increased rate of discontinuation according to gross hematuria and systemic adverse reactions with bacillus Calmette-Guérin induction therapy) was statistically significant (P = 0.0179). CONCLUSIONS Most patients who completed bacillus Calmette-Guérin maintenance therapy experienced local adverse reactions (≥G2) during the maintenance therapy. Gross hematuria and systemic adverse reactions during bacillus Calmette-Guérin induction therapy might be related to the discontinuation of bacillus Calmette-Guérin maintenance therapy because of severe adverse reactions.

Abstract
Context: Bacillus Calmette-Guerin (BCG) therapy is the standard treatment for nonmuscle-invasive bladder cancer (NMIBC). However, its toxicity is a major concern. Aim: If we reduce the number of BCG doses by half and replace the second half with epirubicin, we may have a lower toxicity while maintaining the same efficacy of BCG. To test this hypothesis, we conducted this study as an update of our previous report. Setting and Design: The study included 607 patients with Ta and T1 NMIBC between January 1994 and December 2008. Materials and Methods: After transurethral resection of bladder tumor (TURBT), the patients received weekly doses of 120 mg BCG alternating with 50 mg epirubicin for six weeks (three weekly doses of each). Maintenance was given. Recurrence, progression rates, and toxicity were assessed. End points were progression, recurrence, and cancer-specific survival. Results: A total of 532 patients were eligible for evaluation (mean age: 58 years; median follow-up: 45 months). Of these, 291 (55%) were free, 157 (29.5%) showed recurrence, and 84 (15.8%) showed muscle-invasive progression. Toxicity developed in 221 patients. These were mild in the majority (167), whereas 10 developed hematuria, 30 severe cystitis, and five systemic complications. The rate of permanent therapy discontinuation was 3.8%. Statistical Analysis Used: SPSS package version 16 and Kaplan-Meier curves were used to evaluate survival. Conclusions: Reducing the frequency of BCG instillations by half and replacing the second half with epirubicin results in a similar efficacy and a lower toxicity compared with historical cases receiving BCG alone. However, further trials are required to support these results.

Abstract
Background Intravesical instillation of Bacillus Calmette-Guérin (BCG) is the treatment of choice for superficial bladder carcinoma. Complications of BCG therapy include local infections and disseminated BCG infection with multiple endorgan complications. Case Presentation We report a case of disseminated, post-treatment BCG infection that initially presented with granulomatous hepatitis and choroiditis. After successful anti-mycobacterial therapy and resolution of the hepatic and ocular abnormalities, the patient developed an acute upper gastrointestinal hemorrhage from an aortoduodenal fistula that required emergency surgery. The resection specimen revealed multifocal, non-caseating granulomas, indicating mycobacterial involvement. Conclusions This case highlights the varied end organ complications of disseminated BCG infection, and the need for vigilance even in immuno-competent patients with a history of intravesical BCG treatment.

Abstract
BACKGROUND & AIMS : Bacillus Calmette-Guérin (BCG) infection causes hepatic injury following granuloma formation and secretion of cytokines which renders mice highly sensitive to endotoxin-mediated hepatotoxicity. Tumor necrosis factor (TNF) is required for granuloma formation and is one of the most important cytokines in liver injury. TNF inhibitors are effective therapies for inflammatory diseases. However, clinical use of non-selective TNF inhibitors is associated with an increased risk of infections. This work investigates the differential roles of soluble TNF (solTNF) and membrane TNF (memTNF) in BCG infection, BCG/LPS- and D-GALN/LPS-induced liver injury. METHODS We have used both genetic and pharmacologic approaches and analyzed liver injury, TLR4, cytokine and iNOS activation induced by BCG, BCG/LPS and D-GALN/LPS. RESULTS BCG infection-induced liver injury is seen in wild-type mice but not in TNF(-/-), memTNF knock-in (KI), and sTNFR1-Fc transgenic mice. Severity of BCG-induced liver injury is correlated with BCG-granuloma number and hepatic expression of TLR4 and iNOS. In addition, protection from liver damage caused by BCG/LPS or D-GALN/LPS administration was observed in TNF(-/-), memTNF KI and sTNFR1-Fc transgenic mice. To extend the genetic findings, we then evaluated whether selective pharmacological inhibition of solTNF by dominant-negative (DN)-TNF neutralization and non-selective inhibition of solTNF and memTNF by anti-TNF antibodies and etanercept (TNFR2-IgG1) can protect the mice from liver injury. Both selective and non-selective inhibition of solTNF protected mice from BCG/LPS and D-GALN/LPS-induced liver damage. CONCLUSIONS These data suggest that memTNF is not mediating liver injury and that selective inhibition of solTNF sparing memTNF may represent a new therapeutic strategy to treat immune-mediated inflammatory liver diseases.

Abstract
OBJECTIVES We carried out a prospective, randomized, controlled trial to investigate the efficacy and safety of both induction and maintenance therapy with intravesical instillation of bacillus Calmette-Guérin (BCG) for high-risk non-muscle invasive bladder cancer (NMIBC). METHODS Intravesical instillation of 80 mg Tokyo strain was given to patients with high-risk NMIBC, including carcinoma in situ (CIS), once weekly for eight consecutive weeks as induction therapy. Patients who achieved complete response (CR) were randomly assigned to either the maintenance group or the observation group. RESULTS A total of 90 patients were enrolled. After induction therapy, 75% of the patients achieved CR and 53 of them were enrolled in the randomized comparative phase. A total of four maintenance instillations were given. Median follow-up was 26.5 and 28.7 months after randomization in the maintenance and the observation group, respectively. Although it was not statistically significant, the 2-year recurrence-free survival rate in the maintenance group (95.8%) was higher than that in the observation group (74.1%, P = 0.078). Univariate analysis identified maintenance therapy as a significant factor influencing recurrence. During induction therapy, 82.2% of patients experienced urination-related adverse drug reactions, but most events were not serious. There were fewer adverse drug reactions with maintenance therapy than with induction therapy. Neither induction therapy nor maintenance therapy reduced patients' quality of life (QOL). CONCLUSIONS These findings show high levels of efficacy and safety of BCG induction treatment for high-risk NMIBC, and suggest that the number of maintenance instillations could probably be reduced without reducing treatment efficacy or influencing QOL.

Abstract
Intravesical instillation of bacillus Calmette-Guérin is the elective treatment for transitional cell and in situ bladder carcinoma. Severe complications occur very seldom but must be known and promptly recognized. We present a case of miliary tuberculosis reactivation secondary to the mentioned treatment.

Abstract
BACKGROUND In Japan, bacillus Calmette-Guerin (BCG: Tokyo 172 strain) instillation is generally performed at a dose of 80 mg once weekly for eight consecutive weeks; however, many adverse effects including severe ones have been reported. We employed a dose of 40 mg once a week for six consecutive weeks in principle for carcinoma in situ (CIS) of the bladder, and retrospectively evaluated its effectiveness and safety. METHODS A total of 43 patients with CIS of the bladder were treated by this method and followed-up for a subsequent 12-79 months (median, 54 months). The patients consisted of 35 males and eight females aged 45-87 years (mean, 67.5 years). Intravesical BCG instillation at a dose of 40 mg was conducted once a week for six consecutive weeks. RESULTS A complete response (CR) was achieved in 84% of the patients, in whom the recurrence-free rate was 72.4% after 3 years and 61.9% after 5 years. The median CR duration was 37.5 months. Two patients underwent total cystectomy, but none died of bladder cancer. As adverse effects, bladder irritation symptoms were observed in 48.8%, pyuria in 46.5%, macroscopic hematuria in 18.6% and fever (>37.5 degrees C) in 9.3%. There were no severe adverse effects requiring discontinuation of drug administration. CONCLUSION Our present study corroborated both the effectiveness and safety of low-dose BCG therapy for CIS of the bladder. This therapy warrants further study by prospective randomized trials in the future.
