Is CIS a Contraindication to Hyperthermic Intravesical Chemotherapy (HIVEC) after BCG-Failure? Cancers (Basel) 2023; 15:cancers15051455. [PMID: 36900247 PMCID: PMC10001134 DOI: 10.3390/cancers15051455] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2023] [Revised: 02/22/2023] [Accepted: 02/23/2023] [Indexed: 03/02/2023] Open
Abstract
CIS of the bladder is associated with a high risk of progression. In the case of BCG failure, radical cystectomy should be performed. For patients who refuse or are ineligible, bladder-sparing alternatives are evaluated. This study aims to investigate the efficacy of Hyperthermic IntraVesical Chemotherapy (HIVEC) depending on the presence or absence of CIS. This retrospective, multicenter study was conducted between 2016 and 2021. Patients with non-muscle-invasive bladder cancer (NMIBC) with BCG failure received 6-8 adjuvant instillations of HIVEC. The co-primary endpoints were recurrence-free survival (RFS) and progression-free survival (PFS). A total of 116 consecutive patients met our inclusion criteria of whom 36 had concomitant CIS. The 2-year RFS rate was 19.9% and 43.7% in patients with and without CIS, respectively (p = 0.52). Fifteen patients (12.9%) experienced progression to muscle-invasive bladder cancer with no significant difference between patients with and without CIS (2-year PFS rate = 71.8% vs. 88.8%, p = 0.32). In multivariate analysis, CIS was not a significant prognostic factor in terms of recurrence or progression. In conclusion, CIS may not be considered a contraindication to HIVEC, as there is no significant association between CIS and the risk of progression or recurrence after treatment.

A systematic review on the available treatment modalities for Bacillus Calmette-Guérin-unresponsive carcinoma in situ and tumors in patients who are ineligible for or decline radical cystectomy. SAGE Open Med 2023; 11:20503121231160408.

Abstract
Introduction Globally, urothelial bladder carcinoma is a disease which carries a poor prognosis. There are various treatment modalities for urothelial bladder carcinoma with intravesical Bacillus Calmette-Guérin immunotherapy being the most efficacious intravesical therapy and the treatment of choice for patients with carcinoma in situ. A number of chemotherapeutic drugs are also available for the management of Ta/T1 tumors such as mitomycin C and epirubicin. However, relapse and progression is quite common. The optimal management of patients with Bacillus Calmette-Guérin-unresponsive disease remains to be a challenge. The purpose of this study was to conduct a systematic review on the treatment modalities available for the management of Bacillus Calmette-Guérin-unresponsive carcinoma in situ and urothelial bladder carcinoma in patients who are ineligible or decline radical cystectomy. Methods Two authors independently searched three databases on the treatment modalities available for the management of Bacillus Calmette-Guérin-unresponsive carcinoma in situ and Bacillus Calmette-Guérin-unresponsive urothelial bladder carcinoma. Results The systematic search resulted in 15 studies. We recommend the use of intravesical CG0070 adenovirus or hyperthermic intravesical chemotherapy mitomycin C in patients with carcinoma in situ only disease. In patients with carcinoma in situ ± Ta/T1 disease, we recommend the use of intravesical radiofrequency-induced chemohyperthermia or electromotive drug administration of mitomycin C. In patients who have Ta/T1 disease, we recommend the use of either hyperthermic intravesical chemotherapy epirubicin or electromotive drug administration mitomycin C followed by chemohyperthermia mitomycin C. If any of these second line therapies fail, an alternative regimen would be a combination of gemcitabine, cabazitaxel, and cisplatin. Conclusion This recommendation is subject to the available resources and clinical expertise available in different hospitals. More studies using study designs such as randomized controlled trials comparing multiple drugs with larger sample sizes and regular follow-up intervals should be performed to accurately assess the different medications and aid in designing guidelines to guide the management of Bacillus Calmette-Guérin-unresponsive non-muscle invasive intravesical bladder cancer.

Abstract
INTRODUCTION Urothelial bladder neoplasm (UBN) is an uncommon lesion in children and adolescents, without established follow-up protocol defined for this patient group. OBJECTIVES To report our experience and long-term follow-up data on pediatric patients with urothelial carcinoma of the urinary bladder. METHODS In this retrospective two center study, we analyzed the perioperative and long-term follow-up data of nine pediatric patients, who presented with neoplasms of urothelial origin within the urinary bladder between 2000 and 2021. RESULTS Nine patients were identified with a mean age of 11.9 years (range 4-19 years) and median follow up of 48 months (range 12-160 month). 7 were male. Gross hematuria was the most common presenting symptom, occurring in 6 patients, followed by accidental finding on US, performed for other reasons. Cystoscopy was performed under general anesthesia, and transurethral resection of the bladder tumors was carried out in the same session. All patients had a solitary tumor with a mean size of 11 mm (range 6-15 mm). Pathology revealed 3 cases of papillary urothelial neoplasm of low malignant potential (PUNLMP), 5 cases of low grade (LG) noninvasive urothelial carcinoma (UC) and one case of high-grade (HG) UC invading lamina propria (pT1). All 8 patients with low grade tumor underwent follow up according to adult follow-up protocols without tumor recurrences to date. The single patient with HG pT1 UC, a 14-year-old female after renal transplantation, who was not eligible for intravesical bacillus Calmette-Guerin (BCG) installations due to immunosuppression, underwent 6 sessions of Radiofrequency-induced Thermo-chemotherapy with mitomycin, without complications. She had no recurrence to date, during a 4-year post treatment follow up. CONCLUSION Pediatric non muscle invasive bladder cancer (NMIBC), seems to have a good prognosis with infrequent recurrences, which might be in favor of a more spacious follow up plan with less invasive diagnostic modalities as opposed to adult NMIBC population. To the best of our knowledge this is the single description of Heated Intravesical Chemotherapy efficacy for HG UC in the pediatric population.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:10825. [PMID: 36078542 PMCID: PMC9518426 DOI: 10.3390/ijerph191710825] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/17/2022] [Revised: 08/25/2022] [Accepted: 08/26/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Conventional and newly emerged intravesical modalities have demonstrated prophylactic effectiveness that may improve quality of life (QoL) in non-muscle invasive bladder cancer. The purpose of this study is to analyze existing QoL evidence in patients receiving any form of intravesical therapy. METHODS A PubMed search without time restriction was conducted to identify all relevant studies in accordance with the PICOT question. Additionally, a search was also performed in the Cochrane library database, Internet, and citation. The CONSORT 2010 checklist and STROBE statement checklist were used to evaluate the risk of bias of the included studies. RESULTS A total of 24 eligible articles were included, which consisted of 11 interventional and 13 observational studies. Intravesical therapy with Bacillus Calmette-Guérin (BCG) or certain chemotherapeutic agents worsens symptom burdens and functional performance during the initial induction phase while continuous improved is observed throughout the maintenance treatment and beyond. Hyperthermia has shown a positive trend in enhancing QoL of patients receiving intravesical chemotherapy, which requires more investigations. However, QoL data were unavailable for other forms of immunotherapy, immune checkpoint inhibitors, electromotive drug administration, and photodynamic therapy. CONCLUSIONS Limited studies suggested the long-term positive impact of intravesical BCG immunotherapy and chemotherapy. However, existing evidence was lacking to clarify the impact of many emerging intravesical therapies that have suggested to be effective and safe, which demands treatment-specific QoL studies.

Abstract
Docetaxel and gemcitabine have different mechanisms of action, are well tolerated as monotherapies, and are affordable. This combination represents a good option for the second-line, bladder-preserving standard of care for non-muscle-invasive bladder cancer unresponsive to bacillus Calmette-Guérin.

Abstract
BACKGROUND The recommended treatment for patients with Bacillus Calmette-Guérin (BCG) unresponsive non-muscle invasive bladder cancer (NMIBC) is radical cystectomy (RC). However, many patients refuse, or are unfit for RC. Therefore, alternative bladder-sparing treatment modalities are needed for BCG-unresponsive NMIBC. In this study we sought to assess the long-term efficacy of hyperthermic intravesical chemotherapy (HIVEC) as alternative to radical cystectomy in BCG-unresponsive non-muscle invasive bladder cancer patients. METHODS AND MATERIALS Retrospectively collected data from 56 patients with BCG-unresponsive NMIBC who received ≥5 HIVEC instillations between October 2014 and March 2020 was analyzed. All patients met the BCG-unresponsive criteria according to the current EAU guideline on NMIBC 2020. Patients were followed-up with cystoscopy and/or bladder biopsies, urine cytology and annually CT-urography. The Primary outcome was the high grade (HG) recurrence-free survival (RFS), defined as the time from the first HIVEC instillation until histologically confirmed intravesical recurrence or last follow-up. The Kaplan Meier method was used to estimate survival outcomes. Secondary outcomes were: complete response rate (CR), adverse events (AE), assessed by the Common Terminology Criteria for Adverse Events v5.0 (CTCAE) and tumor progression to muscle invasive disease or distant metastases. RESULTS The median follow-up was 32.2 months (IQR 13.7-44.8). The 1- and 2-year HG-RFS was 53% (SE:6.8) and 35% (SE:6.9), respectively. The CR for patients with CIS was 70% (21/30) at 6 months. Overall, 80% of the population developed an AE, only 1 was classified as CTCAE ≥3. Limitation of this study was the small sample size. CONCLUSION HIVEC resulted in a 2-year HG-RFS of 35% for BCG-unresponsive NMIBC patients without severe side-effects and therefore HIVEC seems to be an alternative treatment option for patients who refuse or are unfit for RC.

Abstract
The Urologic Oncology Journal was founded 25 years ago and we reviewed the literature since that time in the area of urothelial cancer to see the progress and pitfalls we have made over this time period. A comprehensive literature search was conducted by the authors involved who are all actively involved in research, clinical trials, and treatment for urothelial cancer and the results were summarized over the past 25 years. The field of urothelial cancer has evolved tremendously in the last 25 years with the incorporation of molecular subtyping, novel imaging, immunotherapy, and robotic surgery. However, treatments such as BCG and radical cystectomy have remained steadfast over the last 25 years. Although we have a better understanding of the biology of bladder cancer, we still have a long way from being able to cure patients with bladder cancer and eliminate morbidity from treatments. Nevertheless, considerable progress has been made since the founding of the Urologic Oncology Journal 25 years ago.

Abstract
PURPOSE OF REVIEW Although radical cystectomy represents the gold standard treatment for patients with high-risk nonmuscle invasive bladder cancer (NMIBC) whose disease does not respond to bacillus Calmette-Guérin (BCG), many patients are unable or unwilling to undergo surgery. The need remains for effective bladder-preserving therapies. This review aims to describe existing treatments, contemporary research in this field and ongoing trials of salvage therapies for patients with BCG-unresponsive NMIBC. RECENT FINDINGS Intravesical chemotherapy has been utilized frequently in this setting. Emerging data on combination regimens such as intravesical gemcitabine and docetaxel and intravesical cabazitaxel, gemcitabine and cisplatin are promising; nevertheless, larger, prospective trials are needed. Meanwhile, the intravenous checkpoint inhibitor pembrolizumab was recently FDA-approved for patients BCG-unresponsive NMIBC. Encouraging clinical trial results for intravesical nadofaragene firadenovec, oportuzumab monatox and ALT-803 + BCG have been released, while data from trials of other treatment strategies, including novel chemotherapy and drug delivery, augmented BCG immunotherapy, adenoviral and gene therapy, targeted therapy, and combination systemic immunotherapy with intravesical agents, are eagerly awaited. SUMMARY Several novel salvage therapies offer promise for patients with BCG-unresponsive NMIBC. Patient selection, efficacy, safety, cost and ease of administration must be carefully considered to determine the optimal treatment approach.

Abstract
BACKGROUND The recurrence rate of non-muscle invasive bladder cancer (NMIBC) is high, despite intravesical treatments. Importantly, patients are frequently unfit or unwilling to undergo a recommended radical cystectomy when standard intravesical treatments fail, due to the substantial risk of morbidity and mortality. For these patients, radiofrequency-induced hyperthermia combined with intravesical chemotherapy (RF-CHT) has shown promising results. We aim to determine treatment outcomes and assess the effect of (ablative) dose. METHODS 299 intensively pretreated patients treated with RF-CHT were included in safety analysis. Of these, 274 patients who fulfilled induction treatments were included in efficacy analysis. Six-month complete response (CR) and durable response were reported for (concomitant) carcinoma in situ (CIS) patients and recurrence-free survival (RFS) for papillary patients. RESULTS For CIS, six-month CR-rate was 56.0%; and durable response rates were 79.7%, 66.5%, and 40.3% at one-, two- and five-year, respectively. RFS rates for papillary patients were 77.9%, 57.5%, and 37.2%, respectively. Patients treated with ablative dose are less likely to develop recurrence (adjusted Hazard Ratio 0.54, p = 0.01), compared to adjuvant dose. CONCLUSIONS RF-CHT is effective in NMIBC patients in whom standard intravesical treatments have failed and should be considered in patients who are unwilling or unfit to undergo radical cystectomy. Patients with CIS or residual papillary tumor at baseline benefit from ablative dose.

Abstract
PURPOSE OF REVIEW The standard diagnosis of carcinoma in situ (CIS) of the bladder, based on white light cystoscopy and urine cytology, is limited because CIS can vary from normal-appearing mucosa to a lesion indistinguishable from an inflammatory process. Intravesical instillation of Bacillus Calmette-Guerin (BCG) remains first-line therapy; however, a significant proportion of cases persist or recur after BCG treatment. This review summarizes recent improvements in the detection and treatment of CIS. RECENT FINDINGS The new optical technologies improve CIS detection, with a potential positive impact on oncological outcomes. The usefulness of MRI-photodynamic diagnosis fusion transurethral resection in CIS detection is unclear and further studies are needed. BCG instillation remains the first-line therapy in CIS patients and seems to improve recurrence and progression rates, especially with the use of maintenance. Intravesical device-assisted therapies could be effective in both BCG-naïve and BCG-unresponsive CIS patients, but further studies are ongoing to clarify their clinical benefit. A phase II clinical trial with pembrolizumab has shown the potential effectiveness of immune checkpoint inhibitors in BCG-unresponsive CIS patients and further trials are ongoing. SUMMARY New optical techniques increase the CIS detection rate. BCG instillation remains the first-line treatment. Immune checkpoint inhibitors could be a future alternative in BCG-naïve and BCG-unresponsive CIS patients.

Abstract
INTRODUCTION The standard intravesical treatment for high risk non muscle invasive bladder cancer (HRNMIBC) is Bacillus Calmette-Guérin (BCG), with failure often resulting in cystectomy. Radiofrequency-Induced Thermo-chemotherapeutic Effect Mitomycin (RITE-MMC) can be an alternative in BCG failure. There has been concern that RITE-MMC may delay an inevitable cystectomy, make it more technically challenging and worsen prognosis. The aim of this study was to assess operative challenges and oncological outcome in patients undergoing cystectomy for HRNMIBC who received RITE-MMC, and contrast them with those that did not. PATIENTS AND METHODS A retrospective study of a prospective cystectomy database was conducted. Patients treated from April 2011 to June 2017 were looked at. Inclusion criteria were HRNMIBC with BCG failure undergoing cystectomy. Patient demographics and tumour characteristics were analysed. Intraoperative blood loss and length of stay were used as surrogate markers for intra-operative difficulty. Kaplan-Meier curves were constructed to analyse all-cause mortality, cancer specific mortality and time to recurrence between the RITE-MMC treatment group and those that did not receive RITE-MMC. A multivariate analysis was conducted to assess factors that may influence readmission. RESULTS Thirty-six patients who received RITE-MMC underwent cystectomy, compared to 102 that did not. Median ages were comparable at 72 and 69 years, respectively. Patients were followed up for a median of 24 months across the 2 groups. The commonest histological stage in both groups was CIS. There were no significant differences in intraoperative blood loss, length of stay and 90-day readmission between the 2 groups. There were proportionally fewer recurrences in the RITE-MMC group (16% vs. 19%) and median time to recurrence was longer in the RITE-MMC group (37 months vs. 24 months). Multivariate analysis did not reveal a significant correlation between pre-op RITE-MMC and post-operative readmission (P = 0.606). Survival curves show no significant difference in time to recurrence across both groups (P = 0.513), and no overall (P = 0.069) or cancer specific mortality (P = 0.129) dis-advantage was noted in the RITE-MMC group. CONCLUSION We have found that RITE-MMC treatment does not result in a technically more challenging cystectomy and does not compromise oncological outcome compared to those patients undergoing cystectomy immediately post-BCG failure. We feel RITE-MMC remains a useful tool in a carefully selected group of patients who may not be willing to accept the morbidity of a cystectomy at the time, without significantly compromising their long-term outcome.

Abstract
PURPOSE OF REVIEW To give an overview of current options for conservative treatment of patients failing intravesical bacillus Calmette-Guerin (BCG) and to discuss emerging approaches with potential future clinical applications. RECENT FINDINGS Radical cystectomy is the standard-of-care for patients failing BCG therapy. In patients unfit or unwilling to undergo surgery, salvage therapy options could be proposed with the aim to offer local cancer control and prevent progression to muscle-invasive disease. Salvage treatments have been conducted using intravesical chemotherapy regimens, chemoradiation or chemohyperthermia. Intravesical agents such as valrubicin, gemcitabine or docetaxel showed response rates varying between 16 and 40%, whereas combination treatments of gemcitabine with docetaxel or mitomycin reported response rates in up to 50% of all patients with durable responses in about one out of three patients. For chemohyperthermia, 2-year recurrence rates between 41 and 56% have been reported. Ongoing clinical trials are evaluating chemoradiation as well as novel approaches such as systemic immunotherapy, viral gene therapy, targeted therapy or vaccination strategies with promising preliminary outcomes. SUMMARY Salvage therapeutic bladder-sparing strategies for BCG failure such as intravesical chemotherapy or chemoradiation should currently only be considered in patients unfit for or refusing surgery. Innovative concepts such as chemohyperthermia, checkpoint inhibitors, targeted therapy or viral gene therapy could lead to major changes in clinical management of BCG failures in the future.

Abstract
Management of patients with bacillus Calmette-Guérin (BCG)-unresponsive, high-risk, non-muscle-invasive bladder cancer (NMIBC) presents a formidable clinical challenge that requires urologists to weigh the competing risks of progression during further intravesical therapy vs. the morbidity of radical cystectomy. The prognosis of high-risk NMIBC recurring after BCG depends on the adequacy of prior BCG, timing of recurrence, and tumor histology. The standard of care is currently radical cystectomy, as effective salvage intravesical therapy has not been established. The development of bladder-sparing treatments has been hampered to date by inconsistent definitions of BCG failure and difficulties in identifying appropriate control treatments in clinical trials. Despite these limitations, the spectrum of salvage therapy is expanding to include enhanced intravesical chemo-, gene, and immuno-therapies. In this review, we provide an overview of these emerging agents in the context of our current understanding of BCG failure and the unique considerations for clinical trial design in this disease state.

Eur Urol Focus 2019; 7:111-116. [PMID: 31005491 DOI: 10.1016/j.euf.2019.04.002] [Citation(s) in RCA: 31] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2019] [Revised: 03/10/2019] [Accepted: 04/04/2019] [Indexed: 11/28/2022]
Abstract
BACKGROUND Between 2013 and 2016, global production of bacillus Calmette-Guérin (BCG) was dramatically reduced due to the collapse of the factory producing BCG Connaught. OBJECTIVE To evaluate the clinical and economic impact of BCG shortage on a cohort of non-muscle-invasive bladder cancer (NMIBC) patients treated during the period of restricted supply. DESIGN, SETTING AND PARTICIPANTS This retrospective, before and after, cost-consequence study included patients with intermediate- and high-risk NMIBC. Those resected between November 2011 and September 2013 (control group) were compared with those resected between October 2013 and December 2016 (study group). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The primary endpoint was the rate of tumor recurrence from 30 d after transurethral resection to the end of follow-up at 24 mo; the secondary endpoints included the average cost of primary treatment, average cost of treatment of recurrence, and excess cost due to BCG shortage per patient. RESULTS AND LIMITATIONS A total of 402 patients were included: 191 in the control group and 211 in the study group. The rate of recurrence at 24 mo was significantly higher in the study group than in the control group (46.9% vs 16.2%; relative risk: 0.7, 95% confidence interval [0.60; 0.82]; p < 0.001). The increased cost due to the decrease in BCG production was estimated to be €783 per patient with a new diagnosis of NMIBC during the period of restricted supply. This is a retrospective analysis at the level of our unit. A more precise evaluation would require a study of a larger cohort of patients. CONCLUSIONS The shortage of BCG between October 2013 and December 2016 had a significant medical and economic impact; there was an increased rate of bladder cancer recurrence, and the total cost of care for intermediate- and high-risk NMIBC was higher. PATIENT SUMMARY In this report, we analyzed the medical and economic impact of bacillus Calmette-Guérin (BCG) shortage that occurred between 2013 and 2016. We found a significant increase of bladder cancer recurrence and progression, and an increase in the number of patients who had to be treated by cystectomy. BCG shortage also had a significant impact on the total cost. Since there are no alternatives to BCG for high-risk non-muscle-invasive bladder cancer patients, BCG production has to be maintained by any means.
