Consensus statements from the Hong Kong Urological Association and the Hong Kong Society of Uro-Oncology on the management of muscle-invasive and advanced urothelial carcinoma. Front Oncol 2025; 15:1564487. [PMID: 40406240 PMCID: PMC12095001 DOI: 10.3389/fonc.2025.1564487] [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: 01/21/2025] [Accepted: 04/10/2025] [Indexed: 05/26/2025] Open
Abstract
Background Muscle-invasive and advanced urothelial carcinoma (UC) are notorious for their high propensity for recurrence and metastasis. Recent advances in novel medications, surgical procedures, and radiotherapy techniques have substantially transformed the treatment landscape of muscle-invasive and advanced UC. It is crucial to navigate the optimal management approaches for muscle-invasive and advanced UC through the increasingly complex matrix of variables. Methods Two professional organisations convened a consensus panel of six urologists and six clinical oncologists with extensive experience in treating urological malignancies. They reviewed the literature on the management of i) non-metastatic, muscle-invasive, and locally advanced UC of the bladder; ii) locally advanced upper tract UC (UTUC); and iii) unresectable locally advanced or metastatic UC (mUC). The panel held multiple meetings to discuss and draft consensus statements using the modified Delphi method. Each drafted statement was anonymously voted on by every panellist. A consensus statement was accepted if ≥ 80% of the panellists chose 'accept completely' or 'accept with some reservation' from the five options, which also included 'accept with major reservation', 'reject with reservation', and 'reject completely'. Results The panel reached a consensus on 63 statements based on current evidence and expert insights. These statements addressed the considerations for different treatment modalities, including surgical approaches, radiotherapy, radiosensitisers, platinum-based chemotherapy, immune checkpoint inhibitors, and antibody-drug conjugates, in the management of different disease entities, including muscle-invasive UC of the bladder, cN1 disease, locally advanced UTUC, unresectable locally advanced/mUC, and oligometastatic bladder cancer. Conclusion These consensus statements are anticipated to serve as a practical recommendation for clinicians in Hong Kong, and possibly the Asia-Pacific region, regarding the management of muscle-invasive and advanced UC.

Abstract
BACKGROUND There is still controversy regarding the safety and efficacy of atezolizumab for the treatment of urothelial carcinoma (UC). This research aimed to extensively investigate the effectiveness and safety of atezolizumab as a therapy for UC. METHODS A thorough literature review was conducted using databases including PubMed, Embase, the Cochrane Library, and Web of Science. The search included studies published from the inception of each database until May 24, 2024. The primary outcomes, progression-free survival (PFS) and overall survival (OS), were calculated using hazard ratios (HRs) and their corresponding 95% confidence intervals (CIs). RESULTS Ten randomized controlled trials (RCTs) totaling 4,148 participants were included in our analysis. Compared to UC patients who received a placebo, either alone or in combination with chemotherapy medications, aggregated data showed that patients with UC who received atezolizumab had significantly longer OS(HR = 0.88, 95% CI [0.83, 0.94], p < 0.0001). Three RCTs also provided data on PFS, showing that patients who received atezolizumab, either in addition to or instead of chemotherapy, had significantly longer PFS than those who received placebo with or without chemotherapy (HR = 0.85, 95% CI [0.76, 0.95], p = 0.004). CONCLUSIONS Atezolizumab has demonstrated significant improvements in OS and PFS among patients with UC, offering crucial insights for decision-making in UC immunotherapy.

Abstract
Testing for PD-L1 expression by IHC is used to predict immune checkpoint blockade (ICB) benefits but has performed inconsistently in urothelial cancer clinical trials. Different approaches are used for PD-L1 IHC. We analyzed paired PD-L1 IHC data on urothelial cancer samples using the SP142 and 22C3 assays from the phase III IMvigor130 trial and found discordant findings summarized by four phenotypes: PD-L1 positive by both assays, PD-L1 positive by the SP142 assay only, PD-L1 positive by the 22C3 assay only, and PD-L1 negative by both assays double negative. PD-L1 positive by both assays and PD-L1 positive by the SP142 assay only urothelial cancers were associated with more favorable ICB outcomes and increased dendritic cell (DC) infiltration. SP142 PD-L1 staining co-localized with DC-LAMP, a DC marker, whereas 22C3 staining was more diffuse. PD-L1 positive by the 22C3 assay only urothelial cancers, associated with worse outcomes, were enriched in tumor cell (TC)-dominant PD-L1 expression. Multiplex IHC in an independent ICB-treated cohort confirmed that TC-dominant PD-L1 expression was associated with shorter survival. Using different PD-L1 assays, we uncovered that SP142 may preferentially stain PD-L1-expressing DCs, key to orchestrating antitumor immunity, whereas TC-dominant PD-L1 expression, which underlies a subset of "PD-L1-positive" specimens, is associated with poor ICB outcomes.

Abstract
The treatment landscape for patients with advanced urothelial carcinoma (UC) has evolved rapidly in recent years. In current guidelines, combination treatment with enfortumab vedotin plus pembrolizumab is the first-line (1L) standard of care, and other recommended 1L treatment options are platinum-based chemotherapy followed by avelumab as switch-maintenance treatment in patients without progression, or combination treatment with nivolumab, cisplatin, and gemcitabine for cisplatin-eligible patients only. Individual patients differ in terms of their health status, disease characteristics, expected toxicities, and treatment preferences; thus, a "one-size-fits-all" approach to treatment is unlikely to be optimal. The availability of several treatment options creates the potential for individualized treatment. In this review, we discuss factors that may be considered when selecting 1L treatment for patients with advanced UC, including efficacy and safety data from phase 3 trials and real-world studies, quality of life, patient priorities for treatment, patient and disease characteristics, treatment sequencing, biomarkers, and treatment access and cost. Patients and physicians should discuss the benefit-risk balance of all available 1L options to enable shared decision-making. Longer follow-up from clinical trials and additional real-world studies are needed to further inform treatment selection.

Abstract
While immunotherapy with immune checkpoint inhibitors (ICIs) has revolutionized the clinical management of various malignancies, a large fraction of patients are refractory to ICIs employed as standalone therapeutics, necessitating the development of combinatorial treatment strategies. Immunogenic cell death (ICD) inducers have attracted considerable interest as combinatorial partners for ICIs, at least in part owing to their ability to initiate a tumor-targeting adaptive immune response. However, compared with either approach alone, combinatorial regimens involving ICD inducers and ICIs have not always shown superior clinical activity. Here, we discuss accumulating evidence on the therapeutic interactions between ICD inducers and immunotherapy with ICIs in oncological settings, identify key factors that may explain discrepancies between preclinical and clinical findings, and propose strategies that address existing challenges to increase the efficacy of these combinations in patients with cancer.

Abstract
Platinum-based chemotherapy has been the standard first-line (1L) treatment for advanced urothelial carcinoma (UC) for decades, based on the proven efficacy and established safety profiles of cisplatin- and carboplatin-based regimens. With the emergence of novel regimens, it is important to reevaluate and contextualize the role of 1L platinum-based chemotherapy. Platinum-based chemotherapy followed by avelumab 1L maintenance in patients without disease progression following platinum-based chemotherapy was established as a standard 1L regimen based on the JAVELIN Bladder 100 phase III trial. More recently, the EV-302 phase III trial showed the superiority of 1L enfortumab vedotin (EV) + pembrolizumab versus platinum-based chemotherapy, and the Checkmate 901 phase III trial showed the superiority of 1L nivolumab + cisplatin/gemcitabine versus cisplatin/gemcitabine alone. These 2 regimens have now been included as standard 1L options in treatment guidelines for advanced UC. EV + pembrolizumab is now the preferred 1L treatment, and in locations where EV + pembrolizumab is not available or individual patients are not considered suitable, recommended options are platinum-based chemotherapy followed by avelumab maintenance or nivolumab + cisplatin-based chemotherapy. In this review, we discuss current treatment options for advanced UC recommended in guidelines, practical considerations with platinum-based chemotherapy, the role of avelumab 1L maintenance, recent phase III trials of EV + pembrolizumab and nivolumab + cisplatin/gemcitabine, safety profiles of recommended 1L treatments, and second-line treatment options.

Abstract
BACKGROUND The IMvigor210 trial demonstrated clinical benefit and manageable toxicity with atezolizumab monotherapy [anti-programmed death-ligand 1 (PD-L1)] in patients with metastatic urothelial carcinoma (UC) in primary analyses. Final efficacy and safety results after long-term follow-up are reported. PATIENTS AND METHODS This phase II single-arm trial of atezolizumab monotherapy in patients with advanced UC included two cohorts: untreated patients ineligible for cisplatin-based chemotherapy (cohort 1; n = 119) and those previously treated with platinum-based chemotherapy (cohort 2; n = 310). Atezolizumab was administered i.v. (1200 mg every 21 days) until progression or unacceptable toxicity. Primary endpoints were independent review facility-assessed confirmed objective response rate (ORR) per RECIST 1.1 in cohort 1 and independent review facility-assessed ORR per RECIST 1.1 and investigator-assessed modified (m)RECIST in cohort 2. Overall survival (OS), efficacy by PD-L1 status, and safety were also assessed. RESULTS At data cut-off (1 June 2023), the median survival follow-up was 96.4 months (range, 0.2-103.4 months) in cohort 1 and 46.2 months [0.2 (censored)-54.9 months] in cohort 2. In cohort 1, the ORR [95% confidence interval (CI)] was 23.5% (16.2% to 32.2%) in all patients and 28.1% (13.8% to 46.8%) in the PD-L1 tumor-infiltrating immune cell (IC)2/3 subgroup. Median OS (95% CI) was 16.3 months (10.4-24.5 months) overall and 12.3 months (6.0-49.8 months) in the PD-L1 IC2/3 subgroup. In cohort 2, the ORR (95% CI) was 16.5% (12.5% to 21.1%) per RECIST 1.1 and 19.7% (95% CI 15.4% to 24.6%) per mRECIST in all patients and 27.0% (18.6% to 36.8%) and 28.0% (19.5% to 37.9%), respectively, in the PD-L1 IC2/3 subgroup. Median OS (95% CI) was 7.9 months (6.7-9.3 months) in all patients and 11.9 months (9.0-22.8 months) in the IC2/3 subgroup. Treatment-related grade 3/4 adverse events occurred in 21.8% (cohort 1) and 18.7% (cohort 2); one treatment-related death occurred in cohort 1. CONCLUSIONS With long-term follow-up, atezolizumab monotherapy demonstrated clinically meaningful efficacy with durable responses in a subset of patients with metastatic UC; there were no new safety signals.

Abstract
Cisplatin-based chemotherapy is currently the first-line standard of care for patients with metastatic urothelial cancer (mUC); however, up to 50% of patients are ineligible for cisplatin, necessitating alternative treatment options. Immune checkpoint inhibitors have been shown to be effective in cisplatin-ineligible patients. However, despite advances in the first-line setting, the prognosis remains poor, and challenges persist in selecting optimal therapies, treatment sequences and combination regimens. Maintenance therapy with avelumab revealed improved overall (OS) and progression-free survival (PFS) compared with best supportive care alone in patients with platinum-responsive mUC. Antibody-drug conjugates and targeted therapy with fibroblast growth factor receptor (FGFR) inhibitors have shown promise in selected patients, particularly in patients with metastatic disease that has progressed despite platinum-based chemotherapy. At the European Society of Medical Oncology Congress in 2023, groundbreaking results were presented from two phase III trials, EV-302/KEYNOTE-A39 and CheckMate 901, focusing on previously untreated mUC. In the former, the combination of enfortumab vedotin and pembrolizumab showed significant improvements in OS, PFS and overall response rate compared with chemotherapy alone; the combination of nivolumab with gemcitabine-cisplatin chemotherapy demonstrated a significant extension in median OS, PFS and overall response rate compared with chemotherapy alone. In addition, erdafitinib therapy resulted in significantly longer OS than chemotherapy among patients with mUC and FGFR alterations after previous treatment with immune checkpoint inhibitors. This comprehensive summary of the current treatment landscape for mUC incorporates clinical trial evidence and discussion of agents that are currently under investigation to provide support for clinical decision making and understanding of future therapeutic approaches.

Abstract
Programmed death 1 blockade (tislelizumab) has been approved for metastatic urothelial carcinoma but not as part of neoadjuvant therapy for muscle-invasive bladder cancer (MIBC). In this multicenter single-arm trial (ChiCTR2000037670), 65 participants with cT2-4aN0M0 MIBC received neoadjuvant gemcitabine-cisplatin plus tislelizumab; 57 of them underwent radical cystectomy (RC). The primary endpoint of pathologic complete response (pCR) rate was 50.9% (29/57, 95% confidence interval (CI) 37.3-64.4%) and the pathologic downstaging (secondary endpoint) rate was 75.4% (43/57, 95% CI 62.2-85.9%) in participants undergoing RC. Genomic and transcriptomic analyses revealed three MIBC molecular subtypes (S): S1 (immune-desert) with activated cell-cycle pathway, S2 (immune-excluded) with activated transforming growth factor-β pathway and S3 (immune-inflamed) with upregulated interferon-α and interferon-γ response. Post hoc analysis showed pCR rates of 16% (3/19, S1), 77% (10/13, S2) and 80% (12/15, S3) (P = 0.006). In conclusion, neoadjuvant gemcitabine-cisplatin plus tislelizumab for MIBC was compatible with an enhanced pCR rate.

[PMID: 39351347 PMCID: PMC11439625 DOI: 10.3389/fonc.2024.1468784] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2024] [Accepted: 08/29/2024] [Indexed: 10/04/2024] Open
Abstract
Introduction In recent years, some clinical studies of first-line treatment for advanced-stage urothelial carcinoma (aUC) have reached the main endpoint, showing inconsistent clinical efficacy. We hope to explore the efficacy and safety of first-line treatment for aUC. Methods The relevant literature from January 2000 to February 2024 was searched, and the R language (version 4.3.1) was used to perform a network meta-analysis based on the JAGS package and GEMTC package under the Bayesian framework. The main indicators included OS, PFS, ORR and adverse events of grade 3 or higher. This study has been registered in PROSPERO (CRD42024525372). Results A total of 8 RCTs involving 5539 patients and 12 treatments were included. Pembrolizumab plus Enfortumab Vedotin (PEM+EV) was significantly better than other groups in OS, PFS and ORR. In terms of OS, PEM+EV was significantly better than nivolumab plus platinum-based chemotherapy (NIVO+platinumCT) (HR=0.60; 95% CI: 0.45-0.81), PEM+platinumCT (HR=0.55; 95%CI: 0.42-0.72), atezolizumab (ATE) + platinumCT (HR=0.57; 95%CI: 0.43-0.75) and platinumCT (HR=0.47; 95%CI: 0.38-0.58). In terms of PFS, PEM+EV was also significantly better than NIVO+platinumCT (HR=0.62; 95%CI: 0.48-0.82), PEM+platinumCT (HR=0.58; 95%CI: 0.45-0.74), ATE+platinumCT (HR=0.55; 95%CI: 0.43-0.69) and platinumCT (HR=0.45; 95%CI: 0.38-0.54). In terms of ORR, PEM+EV had a significant be nefit compared with other treatment measures, which was 2.63 times that of platinumCT (OR=2.63; 95%CI: 2.00-3.45). The adverse events of grade 3 or higher in immunotherapy (ATE, PEM, durvalumab) was significantly lower than other treatment measures. Conclusions PEM+EV can significantly prolong OS and PFS compared with other treatments, and has a higher ORR. The adverse events of grade 3 or higher of ATE was the lowest.

Cost-effectiveness of nivolumab plus gemcitabine-cisplatin as first-line treatment for advanced urothelial carcinoma in China and the United States. Front Immunol 2024; 15:1426024. [PMID: 39346914 PMCID: PMC11427378 DOI: 10.3389/fimmu.2024.1426024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2024] [Accepted: 08/27/2024] [Indexed: 10/01/2024] Open
Abstract
Objective Nivolumab, recently proven in a phase 3 clinical trial (CheckMate 901) to enhance survival when combined with gemcitabine-cisplatin for advanced urothelial carcinoma. This study aimed to assess its cost-effectiveness against gemcitabine-cisplatin alone, from US and Chinese payers' perspectives. Methods A partitioned survival model was established to assess the life-years, quality-adjusted life-years (QALYs), lifetime costs, and incremental cost-effectiveness ratios (ICERs) of nivolumab plus gemcitabine-cisplatin versus gemcitabine-cisplatin alone as first-line treatment for advanced urothelial carcinoma. Univariate, two-way, and probabilistic sensitivity analyses were conducted to assess the model's robustness. Additionally, subgroup analyses were performed. Results Nivolumab plus gemcitabine-cisplatin and gemcitabine-cisplatin achieved survival benefits of 4.238 life-years and 2.979 life-years for patients with advanced urothelial carcinoma, respectively. Compared with gemcitabine-cisplatin, nivolumab plus gemcitabine-cisplatin resulted in ICERs of $116,856/QALY in the US and $51,997/QALY in China. The probabilities of achieving cost-effectiveness at the current willingness-to-pay thresholds were 77.5% in the US and 16.5% in China. Cost-effectiveness could be reached if the price of nivolumab were reduced to $920.87/100mg in China. Subgroup analyses indicated that the combination had the highest probability of cost-effectiveness in patients under 65 or with an Eastern Cooperative Oncology Group (ECOG) performance-status score of 0 in the US and China. Conclusion Nivolumab plus gemcitabine-cisplatin first-line treatment for advanced urothelial carcinoma results in longer life expectancy than gemcitabine-cisplatin, but is not cost-effective in China at current price. However, cost-effectiveness is likely to be achieved in most patient subgroups in the US.

Abstract
Programmed death receptor-1 (PD-1) and its ligand, programmed death ligand-1 (PD-L1) are essential molecules that are key in modulating immune responses. PD-L1 is constitutively expressed on various immune cells, epithelial cells, and cancer cells, where it functions as a co-stimulatory molecule capable of impairing T-cell mediated immune responses. Upon binding to PD-1 on activated T-cells, the PD-1/PD-L1 interaction triggers signaling pathways that can induce T-cell apoptosis or anergy, thereby facilitating the immune escape of tumors. In urological cancers, including bladder cancer (BCa), renal cell carcinoma (RCC), and prostate cancer (PCa), the upregulation of PD-L1 has been demonstrated. It is linked to poor prognosis and enhanced tumor immune evasion. Recent studies have highlighted the significant role of the PD-1/PD-L1 axis in the immune escape mechanisms of urological cancers. The interaction between PD-L1 and PD-1 on T-cells further contributes to immunosuppression by inhibiting T-cell activation and proliferation. Clinical applications of PD-1/PD-L1 checkpoint inhibitors have shown promising efficacy in treating advanced urological cancers, significantly improving patient outcomes. However, resistance to these therapies, either intrinsic or acquired, remains a significant challenge. This review aims to provide a comprehensive overview of the role of the PD-1/PD-L1 signaling pathway in urological cancers. We summarize the regulatory mechanism underlying PD-1 and PD-L1 expression and activity, including genetic, epigenetic, post-transcriptional, and post-translational modifications. Additionally, we discuss current clinical research on PD-1/PD-L1 inhibitors, their therapeutic potential, and the challenges associated with resistance. Understanding these mechanisms is crucial for developing new strategies to overcome therapeutic limitations and enhance the efficacy of cancer immunotherapy.

Abstract
Urothelial bladder cancer is one of the most common malignant tumors of the urinary system, which accounts for 90~95% of urothelial carcinoma. Despite the current standard neoadjuvant management for localized urothelial MIBC (T2-4cN0M0) is cisplatin-based chemotherapy before radical cystectomy, there still had poor performances and less overall survival benefits in patients with localized urothelial MIBC. Moreover, nearly half of MIBC patients were ineligible for receiving cisplatin because of chronic kidney disease and performance status. Although immunotherapy, immune checkpoint inhibitors (ICIs) has been identified as first or second-line treatments for localized and metastasis bladder cancer based on less adverse reactions and favorable outcomes, neoadjuvant immunotherapy had rarely used for the treatment of these patients because of less large-scale clinical randomized studies and limited outcomes. Therefore, we reviewed the advances of efficacy and safety with neoadjuvant immunotherapy for urothelial bladder cancer depended on published articles and clinical studies, which could provide more theoretical evidences and promising strategy for clinical therapeutic development.

A Head-to-Head Comparison of the First-Line Treatments for Locally Advanced or Metastatic Urothelial Cancer: Is There Still a Role for Chemotherapy? Cancers (Basel) 2024; 16:2400. [PMID: 39001462 PMCID: PMC11240305 DOI: 10.3390/cancers16132400] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2024] [Revised: 06/24/2024] [Accepted: 06/27/2024] [Indexed: 07/16/2024] Open
Abstract
BACKGROUND Patients with locally advanced/metastatic urothelial cancer have been conventionally treated with platinum-based chemotherapy. Recently, numerous new treatments have been proposed to improve overall survival (OS) and reduce adverse effects, but no direct head-to-head comparisons among these agents are available. METHODS The treatments evaluated in our analyses included (a) monotherapy with immune checkpoint inhibitors (ICI); (b) combinations of an ICI with chemotherapy; and (c) combinations of an ICI with other drugs. Using OS as the endpoint, a series of indirect comparisons were performed to rank the most effective regimens against both chemotherapy and each other. Our analysis was based on the application of an artificial intelligence software program (IPDfromKM method) that reconstructs individual patient data from the information reported in the graphs of Kaplan-Meier curves. RESULTS A total of five studies published in six articles were included. In our main analysis, nivolumab plus chemotherapy showed better OS compared to chemotherapy (HR = 0.70, 95% CI: 0.59-0.82), while durvalumab plus tremelimumab showed no OS benefit (HR = 0.95, 95% CI 0.82-1.11). More interestingly, enfortumab vedotin plus pembrolizumab significantly prolonged OS compared to both chemotherapy alone (HR = 0.53, 95% CI 0.45-0.63) and nivolumab plus chemotherapy (HR = 0.76, 95% CI 0.60-0.97). DISCUSSION AND CONCLUSION Among new treatments for locally advanced and metastatic urothelial cancer, enfortumab vedotin plus pembrolizumab showed the best efficacy in terms of OS. Our results support the use of this combination as a first-line treatment in this setting.

Abstract
The management of advanced bladder carcinoma involves a multidisciplinary approach, but the prognosis remains poor for many patients. The immune system plays a crucial role in this disease, influencing both tumor development and response to treatment, and exploiting the immune system against the tumor can be a valuable strategy to destroy neoplastic cells. This is the biological principle underlying Bacillus Calmette-Guérin (BCG) use and, more recently, immune checkpoint inhibitors (ICIs), like PD-1 (programmed death-1)/PD-L1 (programmed death-ligand 1) inhibitors. In fact, one of the best studied immune checkpoints is represented by the PD-1/PD-L1 axis, which is a well-known immune escape system adopted by neoplastic bladder cells. PD-L1 expression has been associated with a higher pathologic stage and has shown prognostic value in bladder carcinoma. Interestingly, high-grade bladder cancers tend to express higher levels of PD-1 and PD-L1, suggesting a potential role of such an axis in mediating disease progression. Immunotherapy with PD-1 and PD-L1 inhibitors has therefore emerged as a valuable treatment option and has shown efficacy in advanced bladder cancer patients, with high PD-L1 expression levels associated with better treatment responses. Our review aims to provide a comprehensive overview of the role of PD-L1 in advanced bladder cancer, focusing on its implications for treatment decisions and the prediction of treatment response. Overall, our work aims to contribute to the understanding of PD-L1 as a predictive biomarker and highlight its role in shaping therapeutic approaches for advanced bladder cancer.

Abstract
In the past decade, immune checkpoint inhibitors (ICI) have been approved for treatment of genitourinary malignancies and have revolutionized the treatment landscape of these tumors. However, despite the remarkable success of these therapies in some GU malignancies, many patients' tumors do not respond to these therapies, and others may experience significant side effects, such as immune-related adverse events (iRAEs). Accordingly, biomarkers and improved prognostic tools are critically needed to help predict which patients will respond to ICI, predict and mitigate risk of developing immune-related adverse events, and inform personalized choice of therapy for each patient. Ongoing clinical and preclinical studies continue to provide an increasingly robust understanding of the mechanisms of the response to immunotherapy, which continue to inform biomarker development and validation. Herein, we provide a comprehensive review of biomarkers of the response to immunotherapy in GU tumors and their role in selection of therapy and disease monitoring.

Abstract
Across the wide range of clinical conditions, there exists a sex imbalance where biological females are more prone to autoimmune diseases and males to some cancers. These discrepancies are the combinatory consequence of lifestyle and environmental factors such as smoking, alcohol consumption, obesity, and oncogenic viruses, as well as other intrinsic biological traits including sex chromosomes and sex hormones. While the emergence of immuno-oncology (I/O) has revolutionised cancer care, the efficacy across multiple cancers may be limited because of a complex, dynamic interplay between the tumour and its microenvironment (TME). Indeed, sex and gender can also influence the varying effectiveness of I/O. Androgen receptor (AR) plays an important role in tumorigenesis and in shaping the TME. Here, we lay out the epidemiological context of sex disparity in cancer and then review the current literature on how AR signalling contributes to such observation via altered tumour development and immunology. We offer insights into AR-mediated immunosuppressive mechanisms, with the hope of translating preclinical and clinical evidence in gender oncology into improved outcomes in personalised, I/O-based cancer care.

In the past decade, the therapeutic arsenal for metastatic bladder cancer has expanded considerably, with the development of immune checkpoint inhibitors (ICIs), antibody-drug conjugates such as enfortumab vedotin, and anti-fibroblast growth factor receptor agents. Clinical trials evaluating ICIs as neoadjuvants, adjuvants, or first- or second-line treatments have produced conflicting results. However, first-line therapeutic strategies have been redefined by the recent publication of results from two clinical trials: CheckMate-901, which demonstrated the superiority of combined treatment with nivolumab and chemotherapy in extending overall survival, and EV-302, which demonstrated that combined treatment with pembrolizumab and enfortumab vedotin reduced the risk of death by 53%. In this review, we discuss the role of ICIs, alone or in combination, in bladder cancer management in the metastatic and adjuvant settings in 2024, considering the latest published trials. The potential role of ICIs as neoadjuvants is also discussed.

Abstract
Management of metastatic bladder cancer has historically been challenging. However, enfortumab vedotin plus pembrolizumab (EV/P) has recently been accepted as a new standard of care, replacing platinum-based chemotherapy, because of improvements in survival and response rates. The benefits of the EV/P combination and some of the questions that arise in this new treatment landscape are discussed.

Atezolizumab plus chemotherapy versus placebo plus chemotherapy in untreated locally advanced or metastatic urothelial carcinoma (IMvigor130): final overall survival analysis results from a randomised, controlled, phase 3 study. Lancet Oncol 2024; 25:29-45. [PMID: 38101433 DOI: 10.1016/s1470-2045(23)00540-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Revised: 10/12/2023] [Accepted: 10/16/2023] [Indexed: 12/17/2023]
Abstract
BACKGROUND IMvigor130 demonstrated statistically significant investigator-assessed progression-free survival benefit with first-line atezolizumab plus platinum-based chemotherapy (group A) versus placebo plus platinum-based chemotherapy (group C) in patients with locally advanced or metastatic urothelial carcinoma. Overall survival was not improved in interim analyses. Here we report the final overall analysis for group A versus group C. METHODS In this global, partially blinded, randomised, controlled, phase 3 study, patients (aged ≥18 years) with previously untreated locally advanced or metastatic urothelial cancer and who had an Eastern Cooperative Oncology Group performance status of 0-2 were enrolled at 221 hospitals and oncology centres in 35 countries. Patients were randomly assigned (1:1:1), with a permuted block method (block size of six) and an interactive voice and web response system, stratified by PD-L1 status, Bajorin risk factor score, and investigator's choice of platinum-based chemotherapy, to receive atezolizumab plus platinum-based chemotherapy (group A), atezolizumab monotherapy (group B), or placebo plus platinum-based chemotherapy (group C). Sponsors, investigators, and patients were masked to assignment to atezolizumab or placebo (ie, group A and group C) and atezolizumab monotherapy (group B) was open label. For groups A and C, all patients received gemcitabine (1000 mg/m2 intravenously; day 1 and day 8 of each 21-day cycle), plus investigator's choice of carboplatin (area under curve 4·5 mg/mL per min or 5 mg/mL per min; intravenously) or cisplatin (70 mg/m2 intravenously), plus either atezolizumab (1200 mg intravenously) or placebo on day 1 of each cycle. Co-primary endpoints of the study were investigator-assessed progression-free survival and overall survival for group A versus group C in the intention-to-treat (ITT) population (ie, all randomised patients), and overall survival for group B versus group C, tested hierarchically. Final overall survival and updated safety outcomes (safety population; all patients who received any amount of any study treatment component) for group A versus group C are reported here. The final prespecified boundary for significance of the overall survival analysis was one-sided p=0·021. The trial is registered with ClinicalTrials.gov, NCT02807636, and is active but no longer recruiting. FINDINGS Between July 15, 2016, and July 20, 2018, 1213 patients were enrolled and randomly assigned to treatment, of whom 851 were assigned to group A (n=451) and group C (n=400). 338 (75%) patients in group A and 298 (75%) in group C were male, 113 (25%) in group A and 102 (25%) in group C were female, and 346 (77%) in group A and 304 (76%) in group C were White. At data cutoff (Aug 31, 2022), after a median follow up of 13·4 months (IQR 6·2-30·8), median overall survival was 16·1 months (95% CI 14·2-18·8; 336 deaths) in group A versus 13·4 months (12·0-15·3; 310 deaths) in group C (stratified hazard ratio 0·85 [95% CI 0·73-1·00]; one-sided p=0·023). The most common grade 3-4 treatment-related adverse events were anaemia (168 [37%] of 454 patients who received atezolizumab plus chemotherapy vs 133 [34%] of 389 who received placebo plus chemotherapy), neutropenia (167 [37%] vs 115 [30%]), decreased neutrophil count (98 [22%] vs 95 [24%]), thrombocytopenia (95 [21%] vs 70 [18%]), and decreased platelet count (92 [20%] vs 92 [24%]). Serious adverse events occurred in 243 (54%) patients who received atezolizumab plus chemotherapy and 196 (50%) patients who received placebo plus chemotherapy. Treatment-related deaths occurred in nine (2%; acute kidney injury, dyspnoea, hepatic failure, hepatitis, neutropenia, pneumonitis, respiratory failure, sepsis, and thrombocytopenia [n=1 each]) patients who received atezolizumab plus chemotherapy and four (1%; unexplained death, diarrhoea, febrile neutropenia, and toxic hepatitis [n=1 each]) who received placebo plus chemotherapy. INTERPRETATION Progression-free survival benefit with first-line combination of atezolizumab plus platinum-based chemotherapy did not translate into a significant improvement in overall survival in the ITT population of IMvigor130. Further research is needed to understand which patients might benefit from first-line combination treatment. No new safety signals were observed. FUNDING F Hoffmann-La Roche.
