Abstract
Introduction Cisplatin-based neoadjuvant chemotherapy (NAC) followed by surgery is the standard treatment for patients with non-metastatic muscle invasive bladder cancer (MIBC). Unfortunately, many patients are not candidates to receive cisplatin due to renal impairment. Additionally, no predictive biomarkers for pathological complete response (pCR) are currently validated in clinical practice. Studies evaluating immune checkpoint inhibitors in the peri-operative setting are emerging with promising results. Clinical trials are clearly required in the neoadjuvant setting in order to improve therapeutic strategies. Methods and analysis Oncodistinct 004 – AURA is an ongoing multicenter phase II randomized trial assessing the efficacy and safety of avelumab single-agent or combined to different NAC regimens in patients with non-metastatic MIBC. Patients are enrolled in two distinct cohorts according to their eligibility to receive cisplatin-based NAC. In the cisplatin eligible cohort, patients are randomized in a 1:1 fashion to receive avelumab combined with cisplatin-gemcitabine or with dose-dense methotrexate-vinblastine-doxorubicin-cisplatin. In the cisplatin ineligible cohort, patients are randomized at a 1:1 ratio to paclitaxel-gemcitabine associated to avelumab or avelumab alone. Primary endpoint is pCR. Secondary endpoints are pathological response and safety. Ethics and dissemination The study is approved by ethics committee from all participating centers. All participants provide informed consent prior inclusion to the study. Once completed, results will be published in peer-reviewed journals. Trial registration number ClinicalTrials.gov (NCT03674424).

Abstract
BACKGROUND: Cisplatin-based neoadjuvant chemotherapy is the standard of care for muscle invasive bladder cancer (MIBC). OBJECTIVE: To compare the efficacy and safety of the two most commonly used cisplatin-based regimens; gemcitabine, and cisplatin (GC) vs. accelerated (dose-dense: dd) or conventional methotrexate, vinblastine, adriamycin, and cisplatin (MVAC). METHODS: We searched MEDLINE, Embase, Scopus and other sources. Outcomes of interest included overall survival, downstaging to pT≤1, pathologic complete response (pCR), recurrence, and toxicity. Meta-analysis was conducted using the random-effects model. RESULTS: We identified 24 studies. Efficacy outcomes were comparable between MVAC and GC for MIBC. dd-MVAC was associated with favorable efficacy compared to GC in terms of downstaging (OR 1.45; 95%CI 1.15–1.82) and all-cause mortality at longest follow-up (OR 0.63; 95%CI 0.44–0.81). However, GC was associated with a better safety profile in terms of febrile neutropenia (OR 0.32; 95%CI 0.13–0.80), anemia (OR 0.32; 95%CI 0.18–0.54), nausea and vomiting (OR 0.27; 95%CI 0.12–0.65) compared to dd-MVAC. Compared to MVAC, patients receiving GC had an increased risk of developing grade 3–4 thrombocytopenia (OR 4.70; 95%CI 1.59–13.89) and a lower risk of nausea and vomiting (OR 0.05; 95%CI 0.01–0.31). Certainty in the estimates was very low for most outcomes. CONCLUSIONS: Efficacy and safety outcomes were comparable between MVAC and GC for MIBC. Including non-peer-reviewed studies showed higher efficacy with dd-MVAC. A phase III randomized trial comparing the two regimens is needed to guide clinical practice.

Abstract
BACKGROUND Multiple single-arm clinical trials showed promising pathologic complete response rates with neoadjuvant immune checkpoint inhibitors (ICIs) in muscle-invasive bladder cancer. We conducted a cost-effectiveness analysis comparing neoadjuvant ICIs with cisplatin-based chemotherapy (CBC). METHODS We applied a decision analytic simulation model with a health care payer perspective to compare neoadjuvant ICIs vs. CBC. For the primary analysis we compared pembrolizumab with ddMVAC. We performed a secondary analysis with gemcitabine/cisplatin as CBC and exploratory analyses with atezolizumab or nivolumab/ipilimumab as ICI. We input pathologic complete response rates from trials or meta-analysis and costs from average sales price. Outcomes of interest included costs, 2-year recurrence-free survival (RFS), and incremental cost-effectiveness ratio (ICER) of cost per 2-year RFS. A threshold analysis estimated a price reduction for ICI to be cost-effective and one-way and probabilistic sensitivity analyses were performed. RESULTS The incremental cost of pembrolizumab compared with ddMVAC was $8,041 resulting in an incremental improvement of 1.5% in 2-year RFS for an ICER of $522,143 per 2-year RFS. A 21% reduction in cost of pembrolizumab would render it more cost-effective with an ICER of $100,000 per 2-year RFS. GC required an 89% pembrolizumab cost reduction to achieve an ICER of $100,000 per 2-year RFS. Atezolizumab appeared to be more cost-effective than ddMVAC. CONCLUSIONS ICIs were not cost-effective as neoadjuvant therapies, except when atezolizumab was compared with ddMVAC. Randomized clinical trials, larger sample sizes and longer follow-up are required to better understand the value of ICIs as neoadjuvant treatments.

Abstract
Radical cystectomy with bilateral pelvic lymph node dissection is the standard of care for muscle invasive bladder cancer (MIBC). The role of neoadjuvant and adjuvant therapy has evolved over the last 3–4 decades, and neoadjuvant chemotherapy (NACT) has now become the standard recommended treatment. However, there are many nuances to this and the utilization of chemotherapy has not been universal. The optimum chemotherapy regimen is still debated. Adjuvant radiation has a role in high-risk patients although not established and immunotherapy has shown promising results. We reviewed the evidence on NACT and adjuvant chemotherapy (ACT) regimens, NACT versus ACT, and the role of adjuvant radiotherapy and immunotherapy in MIBC.

Abstract
INTRODUCTION A decrease in relative-dose intensity (RDI) of chemotherapy has been shown to be associated with poor patient outcomes in solid tumors and non-Hodgkin's lymphoma. The actual delivered chemotherapy dose received by patients can be influenced by dose reductions and treatment delays, often due to toxicities, most commonly chemotherapy-induced neutropenia (CIN). AREAS COVERED We review seminal evidence and more recent studies that have shown an association between higher RDI and improved patient survival. A smaller number of studies has shown no association between RDI and outcomes. These differences may be due to study limitations, including low power, differences in patient and disease characteristics, or the chemotherapeutic regimen. We describe guidelines recommendations to prevent and treat CIN with granulocyte-colony stimulating factor (G-CSF) and describe novel approaches to prevent neutropenia that are being developed that may provide greater value and be associated with fewer adverse events than standard G-CSF options. EXPERT OPINION Maintaining RDI is important to ensure optimal patient outcomes. This can be achieved through the proper administration of G-CSF prophylaxis and treatment. Newer agents in development to treat and/or prevent CIN are entering regulatory review and may potentially change the treatment landscape for CIN in the future.

Abstract
OBJECTIVES To evaluate outcomes of patients achieving a post-treatment pathological stage of <ypT2N0 at radical cystectomy (RC) following neoadjuvant chemotherapy (NAC) for muscle-invasive bladder cancer (MIBC) to identify an optimal definition of pathological response. PATIENTS AND METHODS Patients from 10 international centres who underwent NAC for cT2-4aN0-1 MIBC and achieved <ypT2N0 disease at RC were included. The primary outcome was time to recurrence, either local or distant. Kaplan-Meier and Cox proportional hazards regression were used to evaluate associations between clinicopathological variables and outcomes. RESULTS A total of 625 patients were included. The median age was 66 years and 80% were male. Gemcitabine and cisplatin (GC, 56%) and methotrexate, vinblastine, doxorubicin and cisplatin (MVAC)/dose-dense (dd)MVAC (32%) were the most common NAC regimens. ypT0, pure ypTis, ypTa ±ypTis and ypT1 ± ypTis were attained in 58.1%, 20.0%, 7.6% and 14.2% of patients, respectively. The cumulative incidence of recurrence at 5 years was 9%, 16%, 29% and 30%, respectively. Pathological stage was prognostic for recurrence, with ypTa ± Tis (hazard ratio [HR] 3.20, 95% confidence interval [CI] 1.40-7.30) and ypT1 ± Tis disease (HR 4.03, 95% CI 2.13-7.63) associated with a significantly higher recurrence risk. Pure ypTis (HR 1.66, 95% CI 0.82-3.38) and the type of NAC regimen (ddMVAC: HR 1.59, 95% CI 0.55-4.56; MVAC: HR 1.18, 9%% CI 0.25-5.54; reference: GC) were not associated with recurrence. CONCLUSION We propose that optimal pathological response after NAC be defined as attainment of ypT0N0/ypTisN0 at RC. Patients with ypTaN0 or ypT1N0 disease (with or without Tis) at RC displayed a significantly higher risk of recurrence and may be candidates for trials investigating adjuvant therapy.

Abstract
Radical cystectomy is curative in only approximately 50% of patients with muscle-invasive bladder cancer. Although perioperative radiotherapy has been tested with the intent of improving locoregional disease control, there currently is no role for this modality in routine care. Perioperative systemic therapy is used with the intent of reducing the risk of systemic recurrence. Robust trial evidence supports the use of neoadjuvant cisplatin-based chemotherapy, with adjuvant chemotherapy offered as an alternative if neoadjuvant therapy is not administered. Perioperative immunotherapy represents the next frontier in perioperative therapy. Further biomarker development is required to guide treatment in individual patients.

Abstract
Simple Summary Bladder cancer is a complex disease, the sixth most common cancer, and one of the most expensive cancers to treat. In the last few decades, there has been a significant decrease in the bladder cancer-related mortality rate, potentially related to decreased smoking prevalence, improvements in diagnosing bladder cancer, and advances in treatment. Those advances in diagnostic tools and therapies and greater understanding of the disease are helping to evolve how bladder cancer is managed. The purpose of this article is to provide a review of bladder cancer pathology, diagnosis, staging, radiologic imaging, and management, and highlight recent developments and research. Abstract Methods: Keyword searches of Medline, PubMed, and the Cochrane Library for manuscripts published in English, and searches of references cited in selected articles to identify additional relevant papers. Abstracts sponsored by various societies including the American Urological Association (AUA), European Association of Urology (EAU), and European Society for Medical Oncology (ESMO) were also searched. Background: Bladder cancer is the sixth most common cancer in the United States, and one of the most expensive in terms of cancer care. The overwhelming majority are urothelial carcinomas, more often non-muscle invasive rather than muscle-invasive. Bladder cancer is usually diagnosed after work up for hematuria. While the workup for gross hematuria remains CT urography and cystoscopy, the workup for microscopic hematuria was recently updated in 2020 by the American Urologic Association with a more risk-based approach. Bladder cancer is confirmed and staged by transurethral resection of bladder tumor. One of the main goals in staging is determining the presence or absence of muscle invasion by tumor which has wide implications in regards to management and prognosis. CT urography is the main imaging technique in the workup of bladder cancer. There is growing interest in advanced imaging techniques such as multiparametric MRI for local staging, as well as standardized imaging and reporting system with the recently created Vesicle Imaging Reporting and Data System (VI-RADS). Therapies for bladder cancer are rapidly evolving with immune checkpoint inhibitors, particularly programmed death ligand 1 (PD-L1) and programmed cell death protein 1 (PD-1) inhibitors, as well as another class of immunotherapy called an antibody-drug conjugate which consists of a cytotoxic drug conjugated to monoclonal antibodies against a specific target. Conclusion: Bladder cancer is a complex disease, and its management is evolving. Advances in therapy, understanding of the disease, and advanced imaging have ushered in a period of rapid change in the care of bladder cancer patients.

Abstract
INTRODUCTION Neoadjuvant cisplatin-based combination chemotherapy improves survival in muscle-invasive bladder cancer. However, response rates and survival remain suboptimal. We evaluated the efficacy, safety, and tolerability of cisplatin plus cabazitaxel. METHODS A phase II single-arm trial was designed to recruit at least 26 evaluable patients. This would give 80% power to detect the primary endpoint, an objective response rate defined as a pathologic complete response plus partial response (pathologic downstaging), measured by pathologic staging at cystectomy (p0 = 0.35 and p1 = 0.60, α = 0.05). RESULTS Objective response was seen in 15 of 26 evaluable patients (57.7%) and more than one- third of patients achieved a pathologic complete response (9/26; 34.6%). Seventy-eight percent of the patients (21/27) completed all cycles of treatment, with only 6.7% of the reported adverse events being graded 3 or 4. There were 6 treatment-related serious adverse event reported, but no suspected unexpected serious adverse reactions. In the patients who achieved an objective response, the median progression-free survival and overall survival were not reached (median follow-up of 41.5 months). In contrast, the median progression-free survival (7.2 months) and overall survival (16.9 months) were significantly worse (P = .001, log-rank) in patients who did not achieve an objective response. CONCLUSION Cabazitaxel plus cisplatin for neoadjuvant treatment of muscle-invasive bladder cancer can be considered a well-tolerated and effective regimen before definitive therapy with higher rates (57.7%) of objective response, comparing favorably to that with of cisplatin/gemcitabine (23%-26%). These results warrant further evaluation in a phase III study.

Abstract
The role of immunotherapy in bladder urothelial cancers is rapidly expanding. Since the initial second-line therapy approval for patients who fail prior platinum-based chemotherapy, the use of immunotherapy with checkpoint inhibitors has been rapidly evolving. There are approved indications for first-line metastatic disease in the platinum-ineligible patients or the cisplatin-ineligible PD-L1 positive patients, and there is a label for high-risk non-muscle-invasive bladder cancer who are BCG-refractory. In addition, a trial on maintenance immunotherapy with avelumab showed positive findings with improvement in overall survival that has also changed standard of care for these patients. There are ongoing clinical trials evaluating its use in the neoadjuvant and adjuvant perioperative muscle-invasive bladder cancer setting. The pivotal trials that led to these FDA approvals and promising and ongoing trials are discussed herein.

Abstract
PURPOSE OF REVIEW Immune-checkpoint inhibitors (CPIs) have been implemented in the treatment algorithm of metastatic urothelial cancer as they have shown higher and more sustained responses compared with conventional second-line chemotherapy. Recently, several clinical trials have reported on CPIs in earlier disease stages such as muscle-invasive bladder cancer (MIBC). This review summarizes ongoing clinical trials and results from early phase clinical trials in muscle invasive and locally advanced bladder cancer. RECENT FINDINGS In phase II clinical trials, neoadjuvant use of CPIs as mono and combination therapy, in patients with MIBC planned for radical cystectomy, has shown promising pathological complete response rates. Whether this will translate in survival benefit remains to be assessed. Combination of CPIs and conventional chemotherapy or other targeted agents promises to increase the efficacy of perioperative systemic therapy with potentially additive toxicities. Recently, preclinical models of combined trimodal therapy with CPIs delivered the proof of principle leading to several ongoing trials in this setting. SUMMARY First results of clinical trials evaluating CPIs in MIBC demonstrate very promising results that warrant further investigation as they could revolutionize management of MIBC in the near future. The trend and hope are toward higher rates of safe and sustained bladder preservation.

Abstract
Bladder cancer accounts for nearly 170,000 deaths worldwide annually. For over 4 decades, the systemic management of muscle-invasive and advanced bladder cancer has primarily consisted of platinum-based chemotherapy. Over the past 10 years, innovations in sequencing technologies have led to rapid genomic characterization of bladder cancer, deepening our understanding of bladder cancer pathogenesis and exposing potential therapeutic vulnerabilities. On the basis of its high mutational burden, immune checkpoint inhibitors were investigated in advanced bladder cancer, revealing durable responses in a subset of patients. These agents are now approved for several indications and highlight the changing treatment landscape of advanced bladder cancer. In addition, commonly expressed molecular targets were leveraged to develop targeted therapies, such as fibroblast growth factor receptor inhibitors and antibody-drug conjugates. The molecular characterization of bladder cancer and the development of novel therapies also have stimulated investigations into optimizing treatment approaches for muscle-invasive bladder cancer. Herein, the authors review the history of muscle-invasive and advanced bladder cancer management, highlight the important molecular characteristics of bladder cancer, describe the major advances in treatment, and offer future directions for therapeutic development.

Does grossly complete transurethral resection improve response to neoadjuvant chemotherapy? Urol Oncol 2020; 38:736.e11-736.e18. [PMID: 32684514 DOI: 10.1016/j.urolonc.2020.05.032] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2019] [Revised: 05/28/2020] [Accepted: 05/31/2020] [Indexed: 12/20/2022]
Abstract
INTRODUCTION There is controversy regarding the benefit of a grossly complete transurethral resection of bladder tumor (TURBT) for muscle-invasive bladder cancer (MIBC) in patients prior to neoadjuvant chemotherapy (NAC). Advocates for this approach suggest a higher response rate to NAC, while others suggest this can increase the surgical risk for no clear benefit. METHODS We retrospectively reviewed our institutional radical cystectomy (RC) database from 2011 to 2018 for patients who received an adequate course of cisplatin-based NAC for nonmetastatic MIBC. Univariable and multivariable logistic regression analyses were performed to identify factors associated with complete response [ypT0] or no residual muscle invasive bladder cancer [ypT < 2] following NAC based on clinicopathologic characteristics and grossly complete or incomplete TURBT. RESULTS A total of 167 patients received NAC followed by RC for MIBC during the study period and 100 patients were included in the analysis due to known status of the completeness of TURBT-of these 49 patients underwent complete resection while 51 patients underwent incomplete resection prior to NAC. There were no significant differences in baseline clinicopathologic characteristics between patients who had complete vs. incomplete TURBT. At the time of RC, the overall ypT0 rate was 24% (n = 24), while the overall rate of ypT < 2 was 45%. On logistic regression, there was no association between completeness of TURBT and ypT0 or ypT < 2. Age, histology, and organ-confined disease were not significantly associated with response to NAC. Only smoking status (current or prior history) was negatively associated with ypT0 on univariable and multivariable analysis (odds ratio = 0.36, 95% confidence interval: [0.14-0.91], P = 0.031). CONCLUSION We found no association between response to cisplatin-based NAC and completeness of TURBT in a cohort of MIBC patients. The study is limited by its retrospective nature and lack of ability to predict response to NAC based on TURBT tissue evaluation.
