Abstract
DNA hypomethylating agents (HMAs) such as decitabine and 5-azacytidine have established roles in the treatment paradigms for myelodysplastic syndrome and acute myelogenous leukemia, where they are considered to exert their anticancer effects by restoring the expression of tumor suppressor genes. Due to their relatively favorable adverse effect profile and known ability to pass through the blood-brain barrier, applications in the treatment of glioblastoma (GBM) and other central nervous system malignancies are under active investigation. The present review examines the types of HMAs currently available, their known and less-understood antineoplastic mechanisms, and the evidence to date of their preclinical and clinical efficacy in glioblastoma and other solid malignancies. The present review discusses the potential synergies HMAs may have with established and emerging GBM treatments, including temozolomide, immune checkpoint inhibitors and cancer vaccines. Recent successes and setbacks in clinical trials for newly diagnosed and recurrent GBM are summarized in order to highlight opportunities for HMAs to improve therapeutic responses. Challenges for future clinical trials are also assessed.

Abstract
A 67-year-old female patient with a muscle-invasive, non-metastatic urothelial bladder cancer (UC) (pT2 G3 cN0 cM0) developed metachronous metastases within 6 months after radical cystectomy with ileal conduit urinary diversion. After a good primary response to platinum-based chemotherapy, treatment was switched to the immune checkpoint inhibitor (ICI) pembrolizumab due to progressive disease. Subsequently the patient underwent selective internal radiotherapy (SIRT) of the liver and received vinflunine as well as a re-challenge with pembrolizumab. Two years after the initial diagnosis, rapid disease progression ultimately led to a switch to 5th line therapy with enfortumab vedotin (EV), which had only been approved in the United States at that time. The antibody-drug conjugate was well tolerated by the patient after dose reduction to 1.0 mg/ kg body weight. Simultaneous irradiation of newly occurring precardiac, hepatic and cerebral metastases were necessary. After 10 months of therapy with EV, tumour regression was observed accompanied with good symptom control. The presented case illustrates the efficacy and tolerability of EV in a heavily pre-treated patient with metastatic UC (mUC).

Abstract
This work provides a summary of guideline recommendations and an expert position on the use of maintenance avelumab therapy based on a review of current international clinical practice guidelines for locally advanced or metastatic urothelial carcinoma (UC). A PubMed literature search was conducted in March 2022 (updated in July 2023) to identify guidelines for locally advanced or metastatic UC. An expert panel (four oncologists and one urologist) reviewed the guidelines and clinical evidence, and discussed practical questions regarding the use of avelumab maintenance therapy in this clinical setting. The National Comprehensive Cancer Network, European Association of Urology and European Society for Medical Oncology guidelines recommend first-line cisplatin-containing chemotherapy for cisplatin-eligible patients, carboplatin-gemcitabine for cisplatin-ineligible patients who are fit for carboplatin, or immunotherapy with programmed death ligand-1 (PD-L1) inhibitors (e.g. atezolizumab) in platinum-ineligible patients. Maintenance avelumab is recommended in patients with response/stable disease following chemotherapy (regardless of PD-L1 status). In patients who relapse after/during chemotherapy, options include immunotherapy, erdafitinib [in those with fibroblast growth factor receptor (FGFR) mutations], enfortumab vedotin or further chemotherapy. The expert panel provided the following practical guidance: (1) consider maintenance avelumab in all eligible patients; (2) continue avelumab until disease progression/unacceptable toxicity; (3) ideally, administer six cycles of platinum-based chemotherapy prior to maintenance avelumab; (4) perform radiological evaluation after four chemotherapy cycles and prior to maintenance avelumab; (5) carboplatin-gemcitabine followed by maintenance avelumab is preferred in cisplatin-ineligible patients (regardless of PD-L1 expression), but consider first-line immunotherapy in PD-L1-positive patients and platinum-ineligible patients (regardless of PD-L1 status); and (6) for patients who relapse on avelumab, second-line options include enfortumab vedotin, FGFR inhibitors (in those with FGFR mutations) or clinical trial inclusion. In conclusion, avelumab maintenance therapy is recommended following platinum-based chemotherapy in all eligible patients with locally advanced or metastatic UC, continued until disease progression or unacceptable toxicity.

Transl Androl Urol 2022; 11:1586-1597. [PMID: 36507483 PMCID: PMC9732693 DOI: 10.21037/tau-22-712] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Accepted: 11/17/2022] [Indexed: 11/25/2022] Open
Abstract
Background The Reporting Items for Practice Guidelines in Healthcare (RIGHT) checklist was developed to improve the reporting quality in clinical practice guidelines (CPGs). CPGs could provide the recommendations for key clinical issues with alternative care options and adherence to them could improve the outcomes. And, high reporting quality CPGs can assist health workers to incorporate the best evidence into the individual practice. There is no evaluation study on the reporting quality of CPGs in bladder cancer (BLCA). This study assessed the reporting quality of CPGs on BLCA and provided new insights for the development of CPGs in this disease. Methods We conducted a systematic search in multiple literature databases, including PubMed, Wanfang, China National Knowledge Infrastructure (CNKI) and China Biology Medicine (CBM) as well as the medical associations and websites of guideline development organizations. Relevant CPGs published between January 2017 and December 2021 were identified. Four trained investigators independently screened the extracted documents to include all eligible CPGs and evaluated whether the items in the RIGHT checklist were reported in each CPG. Subsequently, the reporting rate of each CPG and item, as well as the mean reporting rate of each domain in the RIGHT checklist was calculated. Results A total of 23 CPGs related to BLCA were finally included, of which, 22 guidelines were written in English and 1 was published in Chinese. The mean reporting rate of the included CPGs was approximately 65%. The reporting rates of the items in each RIGHT domain were 77% for basic information domain, 75% for recommendations domain, 72% for evidence domain, 69% for background domain, 43% for funding and declaration and management of interest domain, 35% for review and quality assurance domain, and 41% for other information domain. The reporting rate was determined as the mean value in Office Excel 2019. Conclusions The reporting quality of BLCA CPGs related to the domains of funding and declaration and management of interest domain, review and quality assurance domain, and other information domain is poor and warrants improvement in the future.

Abstract
AbstractEnhancer RNAs (eRNAs) can participate in enhancer regulation and target gene transcription, thus affecting the occurrence and development of tumors. In this study, we identified eRNAs closely related to bladder cancer (BLCA). Gene expression profiles and clinical information from The Cancer Genome Atlas (TCGA) database were used in this study. The Atlas of Noncoding RNAs in Cancer (TANRIC) co-expression data was also studied to evaluate correlations between the inferred levels of eRNA and its predicted target genes. Moreover, we evaluated differences in tumor microenvironment between high and low ID2-AS1 expression groups, and predicted the response of high- and low-expression groups to immune checkpoint inhibitor (ICI) treatment. Finally, we analyzed the prognostic value of ID2-AS1 in different tumors. ID2-AS1 and ID2 were identified as eRNAs and target genes related to the prognosis of BLCA. Low ID2-AS1 levels were associated with advanced age, low overall survival, high histological grade, and late BLCA staging. ID2-AS1 appeared to regulate epithelial mesenchymal transition, mitotic spindle assembly, and angiogenesis, thereby affecting BLCA progression. The ID2-AS1 high-expression group had better ICI treatment response. In addition, ID2-AS1 also had prognostic value in other cancers. ID2-AS1 helps predict prognostic and immunotherapeutic effects in BLCA.

Abstract
BACKGROUND Effective maintenance therapy for urothelial carcinoma (UC) is needed to delay progression after first-line chemotherapy. OBJECTIVE To evaluate S-588410, a cancer peptide vaccine containing five human leukocyte antigen (HLA)-A*24:02-restricted epitope peptides derived from five cancer-testis antigens (DEPDC1, MPHOSPH1, URLC10, CDCA1, and KOC1) in chemotherapy-treated, clinically stable patients with advanced or metastatic UC. MATERIALS AND METHODS This open-label, international, phase 2 trial enrolled patients with UC who had completed≥4 cycles of first-line platinum-containing chemotherapy without disease progression. Forty-five HLA-A*24:02-positive patients received subcutaneous injections of S-588410 (Montanide ISA 51 VG with 1 mg/mL of each peptide) weekly for 12 weeks then once every 2 weeks thereafter for up to 24 months. Thirty-six HLA-A*24:02-negative patients did not receive S-588410 (observation group). The primary endpoint was the rate of cytotoxic T-lymphocyte (CTL) induction against≥1 of the peptides at 12 weeks. RESULTS The CTL induction rate in the S-588410 group was 93.3% (p < 0.0001, one-sided binomial test with a rate of≤50% as the null hypothesis). The antitumor response rate was 8.9% in the S-588410 group and 0% in the observation group; median progression-free survival was 18.1 versus 12.5 weeks and median overall survival was 71.0 versus 99.0 weeks, respectively. The most frequent treatment-emergent adverse event was injection-site reactions (47 events, grades 1-3) reported in 93.3% (n = 42/45) of participants. CONCLUSIONS S-588410 demonstrated a high CTL induction rate, acceptable safety profile, and modest clinical response, as maintenance therapy in participants with advanced or metastatic UC who had received first-line platinum-based chemotherapy (EudraCT 2013-005274-22).

Abstract
Immune checkpoint inhibitors (ICIs) have led to a significant change in the treatment of urological tumors where several agents are currently approved. Yet, most patients discontinue treatment due to disease progression or after the onset of severe immune-related adverse events (IRAEs). Following promising results in melanoma patients, retreatment with an ICI is receiving increasing attention as an attractive option for selected patients. We performed a literature review focusing on the feasibility, safety, timing and activity of ICI rechallenge in genitourinary cancers where very little information is available. We classified the different ICI retreatment strategies into three main clinical scenarios: retreatment after terminating a prior course of ICI while still on response; retreatment after interruption due to IRAEs; retreatment after progression while on ICI therapy. The pros and cons of these options in the field of urological tumors are then discussed, and critical suggestions proffered for the design of future clinical trials.

Abstract
Therapies based on the use of immune checkpoint inhibitors (ICIs), such as nivolumab, pembrolizumab, ipilimumab, atezolizumab, avelumab, and durvalumab, have proven effective in the treatment of metastatic urological neoplasms. Recently, it has been hypothesized that the use of this type of treatment prior to surgery could lead to an increased difficulty in renal and bladder surgeries. The literature concerning this topic, however, is still scarce and non-consensual. In our systematic review, we used the PRISMA guidelines methodology to search the pertinent literature available up to June 18, 2020 in PubMed. Additionally, we searched the related grey literature in the abstracts of the meetings of the American Society of Clinical Oncology (ASCO), American Society of Clinical Oncology Genitourinary (ASCO-GU), European Society of Medical Oncology (ESMO), and American Urological Association (AUA) from 2015 to 2020. We were able to find only 16 publications that addressed the use of ICIs prior to surgery in kidney and bladder neoplasms. The results were conflicting, and usually the issue of surgical difficulties after the use of ICIs was not directly approached. We hope that our publication may raise the awareness towards the need to further investigate the effects of neoadjuvant ICIs on surgical outcomes in urologic cancers.

The Role of Interleukin-1-Receptor-Antagonist in Bladder Cancer Cell Migration and Invasion. Int J Mol Sci 2021; 22:ijms22115875. [PMID: 34070905 PMCID: PMC8198563 DOI: 10.3390/ijms22115875] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Revised: 05/21/2021] [Accepted: 05/27/2021] [Indexed: 11/30/2022] Open
Abstract
Background: The interleukin-1-receptor antagonist IL1RA (encoded by the IL1RN gene) is a potent competitive antagonist to interleukin-1 (IL1) and thereby is mainly involved in the regulation of inflammation. Previous data indicated a role of IL1RA in muscle-invasive urothelial carcinoma of the bladder (UCB) as well as an IL1-dependent decrease in tissue barrier function, potentially contributing to cancer cell invasion. Objective: Based on these observations, here we investigated the potential roles of IL1RA, IL1A, and IL1B in bladder cancer cell invasion in vitro. Methods: Cell culture, real-time impedance sensing, invasion assays (Boyden chamber, pig bladder model), qPCR, Western blot, ELISA, gene overexpression. Results: We observed a loss of IL1RA expression in invasive, high-grade bladder cancer cell lines T24, UMUC-3, and HT1197 while IL1RA expression was readily detectable in the immortalized UROtsa cells, the non-invasive bladder cancer cell line RT4, and in benign patient urothelium. Thus, we modified the invasive human bladder cancer cell line T24 to ectopically express IL1RA, and measured changes in cell migration/invasion using the xCELLigence Real-Time-Cell-Analysis (RTCA) system and the Boyden chamber assay. The real-time observation data showed a significant decrease of cell migration and invasion in T24 cells overexpressing IL1RA (T24-IL1RA), compared to cells harboring an empty vector (T24-EV). Concurrently, tumor cytokines, e.g., IL1B, attenuated the vascular endothelial barrier, which resulted in a reduction of the Cell Index (CI), an impedance-based dimensionless unit. This reduction could be reverted by the simultaneous incubation with IL1RA. Moreover, we used an ex vivo porcine organ culture system to evaluate cell invasion capacity and showed that T24-IL1RA cells showed significantly less invasive capacity compared to parental T24 cells or T24-EV. Conclusions: Taken together, our results indicate an inverse correlation between IL1RA expression and tumor cell invasive capacity and migration, suggesting that IL1RA plays a role in bladder carcinogenesis, while the exact mechanisms by which IL1RA influences tumor cells migration/invasion remain to be clarified in future studies. Furthermore, we confirmed that real-time impedance sensing and the porcine ex vivo organ culture methods are powerful tools to discover differences in cancer cell migration and invasion.

Abstract
CONTEXT Numerous health care organizations have established guidelines on diagnosis and treatment of bladder cancer. However, the lack of a standardized guideline development approach results in considerable differences of the guidelines' methodological quality. OBJECTIVE To assess the methodological quality of all relevant clinical practice guidelines (CPGs) for urinary bladder cancer and provide a reference for clinicians in choosing guidelines of high methodological quality. EVIDENCE ACQUISITION A systematic literature search was conducted in Medline via PubMed, 4 CPG databases, and 7 databases of interdisciplinary organizations. CPGs for non-muscle-invasive bladder cancer (NMIBC) and muscle-invasive bladder cancer (MIBC) with the topics screening, pathology, diagnosis, treatment, and aftercare published in English language between 2012 and 2018 were included. The CPG quality was analyzed using the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument. EVIDENCE SYNTHESIS A total of 16 CPGs were included for the quality appraisal. Because of predefined criteria, 5 CPGs were "strongly recommended" (American Urological Association NMIBC, European Association of Urology [EAU] NMIBC, EAU MIBC, National Institute for Health and Care Excellence, and National Comprehensive Cancer Network), 4 CPGs were "weakly recommended" and 7 CPGs were "not recommended." CONCLUSIONS The methodological quality of bladder cancer guidelines is diverse. Considering the rapid development of new therapies (e.g., immune checkpoint inhibitors), "living guidelines" of high methodological quality, such as the EAU NMIBC or MIBC guideline, will become more relevant in the future guideline's landscape.

Abstract
PURPOSE Poor prognosis of patients with muscle-invasive bladder cancer that often metastasizes drives the need for discovery of molecular determinants of bladder cancer progression. Chondroitin sulfate proteoglycans, including CD44, regulate cancer progression; however, the identity of a chondroitinase (Chase) that cleaves chondroitin sulfate from proteoglycans is unknown. HYAL-4 is an understudied gene suspected to encode a Chase, with no known biological function. We evaluated HYAL-4 expression and its role in bladder cancer. EXPERIMENTAL DESIGN In clinical specimens, HYAL-4 wild-type (Wt) and V1 expression was evaluated by RT-qPCR, IHC, and/or immunoblotting; a novel assay measured Chase activity. Wt and V1 were stably expressed or silenced in normal urothelial and three bladder cancer cell lines. Transfectants were analyzed for stem cell phenotype, invasive signature and tumorigenesis, and metastasis in four xenograft models, including orthotopic bladder. RESULTS HYAL-4 expression, specifically a novel splice variant (V1), was elevated in bladder tumors; Wt expression was barely detectable. V1 encoded a truncated 349 amino acid protein that was secreted. In bladder cancer tissues, V1 levels associated with metastasis and cancer-specific survival with high efficacy and encoded Chase activity. V1 cleaved chondroitin-6-sulfate from CD44, increasing CD44 secretion. V1 induced stem cell phenotype, motility/invasion, and an invasive signature. CD44 knockdown abrogated these phenotypes. V1-expressing urothelial cells developed angiogenic, muscle-invasive tumors. V1-expressing bladder cancer cells formed tumors at low density and formed metastatic bladder tumors when implanted orthotopically. CONCLUSIONS Our study discovered the first naturally-occurring eukaryotic/human Chase and connected it to disease pathology, specifically cancer. V1-Chase is a driver of malignant bladder cancer and potential predictor of outcome in patients with bladder cancer.

Abstract
Bladder cancer accounts for high morbidity and mortality around the world and its incidence rate is suggested to be higher in following years. A number of factors involve in bladder cancer development such as lifestyle and drugs. However, it appears that genetic factors play a significant role in bladder cancer development and progression. Phosphatase and tensin homolog (PTEN) is a cancer-related transcription factor that is corelated with reduced proliferation and invasion of cancer cells by negatively targeting PI3K/Akt/mTOR signaling pathway. In the present review, we aimed to explore the role of PTEN in bladder cancer cells and how upstream modulators affect PTEN in this life-threatening disorder. Down-regulation of PTEN is associated with poor prognosis, chemoresistance and progression of cancer cells. Besides, microRNAs, long non-coding RNAs, circular RNAs and other molecular pathways such as NF-kB are able to target PTEN in bladder cancer cells. Notably, anti-tumor drugs such as kaempferol, β-elemene and sorafenib upregulate the expression of PTEN to exert their inhibitory effects on bladder cancer cells.

Naturally-Occurring Invasive Urothelial Carcinoma in Dogs, a Unique Model to Drive Advances in Managing Muscle Invasive Bladder Cancer in Humans. Front Oncol 2020; 9:1493.

Abstract
There is a great need to improve the outlook for people facing urinary bladder cancer, especially for patients with invasive urothelial carcinoma (InvUC) which is lethal in 50% of cases. Improved outcomes for patients with InvUC could come from advances on several fronts including emerging immunotherapies, targeted therapies, and new drug combinations; selection of patients most likely to respond to a given treatment based on molecular subtypes, immune signatures, and other characteristics; and prevention, early detection, and early intervention. Progress on all of these fronts will require clinically relevant animal models for translational research. The animal model(s) should possess key features that drive success or failure of cancer drugs in humans including tumor heterogeneity, genetic-epigenetic crosstalk, immune cell responsiveness, invasive and metastatic behavior, and molecular subtypes (e.g., luminal, basal). Experimental animal models, while essential in bladder cancer research, do not possess these collective features to accurately predict outcomes in humans. These key features, however, are present in naturally-occurring InvUC in pet dogs. Canine InvUC closely mimics muscle-invasive bladder cancer in humans in cellular and molecular features, molecular subtypes, immune response patterns, biological behavior (sites and frequency of metastasis), and response to therapy. Thus, dogs can offer a highly relevant animal model to complement other models in research for new therapies for bladder cancer. Clinical treatment trials in pet dogs with InvUC are considered a win-win-win scenario; the individual dog benefits from effective treatment, the results are expected to help other dogs, and the findings are expected to translate to better treatment outcomes in humans. In addition, the high breed-associated risk for InvUC in dogs (e.g., 20-fold increased risk in Scottish Terriers) offers an unparalleled opportunity to test new strategies in primary prevention, early detection, and early intervention. This review will provide an overview of canine InvUC, summarize the similarities (and differences) between canine and human InvUC, and provide evidence for the expanding value of this canine model in bladder cancer research.

Abstract
BACKGROUND The present study (VINGEM) is the first randomised trial comparing vinflunine/gemcitabine (VG) to standard carboplatin/gemcitabine (CG) in patients with advanced urothelial carcinoma (aUC) ineligible for treatment with cisplatin. PATIENTS AND METHODS Patients with aUC, creatinine clearance 30-60 ml/min, performance status ≤1 and no prior chemotherapy for metastatic disease were randomised to the experimental arm (vinflunine 280 or 250 mg/m2 day 1, gemcitabine 1000 mg/m2 days 1 and 8, q21 days) or the control arm (carboplatin AUC 4.5 day 1, gemcitabine 1000 mg/m2 days 1 and 8, q21 days). Primary end-point was progression-free survival (PFS). RESULTS Sixty-two patients were randomised; a total of 59 patients were treated (29 VG, 30 CG). There was no significant difference in PFS between the treatment arms: median 6.2 months for VG versus 6.3 months for CG (hazard ratio [HR]: 0.75, 95% confidence interval [CI]: 0.44-1.28; P = 0.293). Median overall survival was 12.5 months for VG versus 10.6 months for CG. The overall response rate (ORR) was higher in the VG arm than in the CG arm (63% versus 40%) but was not statistically significant in the intention-to-treat analysis. Furthermore, VG showed a high complete response (CR) rate, 22% versus 3% in CG. In the per-protocol group, both ORR and CR were significantly higher for VG than for CG. The most common adverse events (AEs) were fatigue, haematological toxicities, gastrointestinal disorders and nausea/vomiting. Common grade III/IV AEs were neutropenia (VG 62%, CG 43%), thrombocytopenia (VG 7%, CG 37%) and febrile neutropenia (VG 31%, CG 7%). CONCLUSIONS The combination of VG did not improve PFS compared with standard treatment with CG in patients unfit for cisplatin due to renal impairment. The response rate of VG indicates, however, an active regimen and warrants further studies. CLINICALTRIALS. GOV NUMBER NCT02665039.

Abstract
Besides evidence- and guideline-based tumor therapy, personalized targeted therapies within study settings or individual experimental settings in advanced cancers without further therapeutic options are emerging. A comprehensive molecular analysis of the tumor in a molecular pathology laboratory is important for all targeted therapy approaches. However, the interpretation of the molecular results is crucial and potential therapeutic conclusions can only be drawn by considering the clinical situation and within a setting of oncological experience. Therefore, the molecular results and their potential impact have to be discussed at a molecular tumor board, an interdisciplinary expert team consisting of clinicians, oncologists, (molecular) pathologists, systems physicians, study teams and where required geneticists. If the molecular tumor board decides a targeted therapeutic approach is appropriate, patients should be enrolled in studies or registries with controlled settings and documentation in order to evaluate the therapeutic concepts. Furthermore, molecular-based individual experimental therapies are possible within extreme clinical situations.

Abstract
BACKGROUND Atezolizumab, a humanised monoclonal antibody targeting PD-L1, is approved for locally advanced/metastatic urothelial carcinoma. SAUL evaluated atezolizumab in a broader, pretreated population, including patients ineligible for the pivotal IMvigor211 phase 3 trial of atezolizumab. OBJECTIVE To determine the safety and efficacy of atezolizumab in an international real-world setting. DESIGN, SETTING, AND PARTICIPANTS Between November 2016 and March 2018 (median follow-up 12.7mo), 1004 patients with locally advanced or metastatic urothelial or nonurothelial urinary tract carcinoma who experienced progression during or after one to three prior therapies for inoperable, locally advanced, or metastatic disease were enrolled. Patients with renal impairment, treated central nervous system metastases, or stable controlled autoimmune disease were eligible; 10% had Eastern Cooperative Oncology Group performance status (ECOG PS) 2 and 98% were platinum pretreated (Clinicaltrials.gov: NCT02928406). INTERVENTION Atezolizumab 1200mg every 3wk until progression or unacceptable toxicity. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The primary endpoint was safety. Secondary efficacy endpoints included overall survival (OS), progression-free survival (PFS), and overall response rate (ORR). RESULTS AND LIMITATIONS The median treatment duration was 2.8mo (range 0-19); 22% remained on treatment and 8% discontinued because of toxicity. Grade ≥3 adverse events occurred in 45% of patients. The most common grade ≥3 treatment-related adverse events were fatigue, asthenia, colitis, and hypertension (each in 1%). Median OS was 8.7mo (95% confidence interval [CI] 7.8-9.9). The 6-mo OS rate was 60% (95% CI 57-63%), median PFS was 2.2mo (95% CI 2.1-2.4), and the ORR was 13% (95% CI 11-16%; 3% complete responses). Among IMvigor211-like patients (excluding ECOG PS 2 and other IMvigor211 exclusion criteria), median OS was 10.0mo (95% CI 8.8-11.9) and 6-mo OS was 65% (95% CI 61-69%). CONCLUSIONS SAUL confirms the tolerability of atezolizumab in a real-world pretreated population with urinary tract carcinoma. Efficacy overall and in the IMvigor211-like subgroup is consistent with previous pivotal anti-PD-L1/PD-1 urothelial carcinoma trials. These results support the use of atezolizumab in urinary tract carcinoma, including patients with limited treatment options. PATIENT SUMMARY In this international study we investigated the efficacy and safety of atezolizumab treatment for advanced urinary tract cancer in a large population of pretreated patients, including those who would not normally be candidates for clinical trials. Patients tolerated the treatment well, even if they had autoimmune disease, were being treated with corticosteroids, or had disease that had spread to their brain. Life expectancy in this study for patients typical of everyday clinical practice was similar to that seen in trials that enrolled only selected fitter patients.
