RESUMEN
AIMS: Treatment options for advanced urothelial carcinoma (aUC) rapidly evolved: besides immunomodulative therapeutic options and inhibitors targeting Fibroblast growth factor receptor (FGFR) alterations, two new antibody-drug conjugates (ADC), sacituzumab govitecan (SG) and enfortumab vedotin (EV), have been approved. However, little is known about the associations of specific aUC properties and the surface target expression of TROP2 and NECTIN-4. Our aim was to characterize associations of TACSTD2/TROP2 and NECTIN-4/NECTIN-4 protein and gene expression with morphomolecular and clinicopathological characteristics of aUC in two large independent cohorts. METHODS AND RESULTS: The TCGA BLCA (n = 405) and the CCC-EMN (n = 247) cohorts were retrospectively analysed. TROP2/TACSTD2 and NECTIN-4/NECTIN-4 are highly expressed at the protein and transcript level in aUC, and their expression status did not correlate with patient survival in both cohorts. NECTIN-4/NECTIN-4 expression was higher in luminal tumours and reduced in squamous aUCs. NECTIN-4 was negative in 10.6% of samples, and 18.4% of samples had low expression (H-score <15). The TROP2 negativity rate amounted to 6.5%. TACSTD2 and NECTIN-4 expression was reduced in neuroendocrine-like and/or protein-based double-negative tumours. TROP2- and NECTIN-4-negative tumours included one sarcomatoid and four neuroendocrine aUC. FGFR3 alterations and PD-L1 expression on tumour and immune cells did not associate with TROP2 or NECTIN-4 expression. CONCLUSIONS: TACSTD2/TROP2 and NECTIN-4/NECTIN-4 are widely expressed in aUC, independent of FGFR3 alterations or PD-L1 expression, thus representing a suitable target for ADC treatment in the majority of aUC. The expression loss was associated with aggressive morphomolecular aUC subtypes, i.e. neuroendocrine(-like) and sarcomatoid aUC.

Results from JAVELIN Bladder 100 established avelumab (anti-PD-L1) first-line maintenance as the standard-of-care treatment for patients with advanced urothelial carcinoma (UC) that has not progressed with first-line platinum-based chemotherapy. We describe the design of JAVELIN Bladder Medley (NCT05327530), an ongoing phase II, multicenter, randomized, open-label, parallel-arm, umbrella trial. Overall, 252 patients with advanced UC who are progression-free following first-line platinum-based chemotherapy will be randomized 1:2:2:2 to receive maintenance therapy with avelumab alone (control group) or combined with sacituzumab govitecan (anti-Trop-2/topoisomerase inhibitor conjugate), M6223 (anti-TIGIT) or NKTR-255 (recombinant human IL-15). Primary end points are progression-free survival per investigator and safety/tolerability of the combination regimens. Secondary end points include overall survival, objective response and duration of response per investigator, and pharmacokinetics.
Urothelial cancer develops in the urinary tract, which contains the parts of the body that move urine from the kidneys to outside of the body. Urothelial cancer is called advanced when it has spread outside of the urinary tract. Chemotherapy is often the first main treatment given to people with advanced urothelial cancer. Avelumab is an immunotherapy drug that can help the body's immune system find and destroy cancer cells. Results from a trial called JAVELIN Bladder 100 looked at avelumab maintenance treatment, which is given after chemotherapy. The trial showed that avelumab maintenance treatment helped people with advanced urothelial cancer live longer than people who were not treated with avelumab. Avelumab also helped people have a longer time without their cancer getting worse. Avelumab is the only approved maintenance treatment available for people with advanced urothelial cancer that has not worsened after chemotherapy. The JAVELIN Bladder Medley trial will assess whether avelumab maintenance treatment given in combination with other anticancer drugs can help people with advanced urothelial cancer live longer and have a longer time without their cancer getting worse compared with avelumab alone. Researchers will also look at the side effects people have when they receive avelumab alone or combined with the other anticancer drugs in this trial. Results will show whether the benefit of avelumab maintenance treatment can be improved by combining avelumab with other anticancer drugs. People started joining this trial in August 2022. Results will be reported in the future. Clinical Trial Registration: NCT05327530 (ClinicalTrials.gov).

For more than four decades, platinum-based chemotherapy regimens have served as the established standard-of-care for advanced urothelial carcinoma (aUC). However, advancements in our understanding of cancer biology and tumor microenvironment have reshaped the therapeutic landscape and prognosis of this incurable disease. Immune checkpoint inhibitors (ICIs) that target programmed cell death 1 (PD-1) and programmed cell death ligand 1 (PD-L1) are firmly established tools in aUC management, leading to enhanced life span and improved quality of life for patients. In patients who achieved stable disease or better following platinum-based chemotherapy, maintenance therapy with the PD-L1 antibody avelumab significantly enhanced overall survival (OS) by approximately 7 months compared to best supportive care in the phase 3 JAVELIN Bladder 100 trial. As a result, avelumab received FDA approval in June 2020 as a maintenance therapy for aUC patients treated with first-line platinum-based chemotherapy. Therefore, aUC care plans should incorporate maintenance avelumab into standard first-line treatment regimens for these patients. The objective of this brief article is to provide insight into the utilization of avelumab, identify patients who may benefit from this treatment, and review the methodology, advantages, potential side effects and their management.

OBJECTIVES: We investigated poor prognosticators in advanced or unresectable urothelial carcinoma, focusing on renal parenchymal invasion (RPI). METHODS: This study included 48 bladder cancer (BC) and 67 upper tract urothelial carcinoma (UTUC) patients treated with pembrolizumab from December 2017 to September 2022 at Kobe University Hospital. Medical records were retrospectively reviewed for clinical characteristics, objective response rate (ORR), progression-free survival (PFS), and overall survival (OS). Multivariate analyses were performed using the Cox proportional hazard regression model to identify parameters associated with either PFS or OS. RESULTS: Of 67 UTUC patients, 23 had RPI and 41 patients did not, while 3 cases could not be evaluated. Patients with RPI were predominantly elderly and had liver metastases. ORR for patients with RPI was 8.7%, while it was 19.5% for those without RPI. PFS was significantly shorter for patients with RPI compared with those without RPI. Patients with RPI had significantly shorter OS than those without RPI. On multivariate analysis, performance status (PS) ≥ 2, neutrophil-lymphocyte ratio (NLR) ≥ 3, C-reactive protein ≥0.3 mg/dL and RPI were independent prognostic factors for PFS. PS ≥ 2, NLR ≥ 3, visceral metastasis and RPI were independent prognostic factors for OS. UTUC patient OS was significantly shorter than BC patient OS, while no significant difference in PFS or OS was observed between BC patients and UTUC patients without RPI. CONCLUSIONS: RPI was a poor prognostic factor in advanced urothelial carcinoma treated with pembrolizumab, possibly resulting in a poorer prognosis for UTUC compared with BC.

Immunotherapy is gradually revolutionizing bladder cancer treatment. In this extensive review published by Hanna et al. in your journal, the authors presented recent studies that are trying to challenge the standard platinum-based chemotherapy as first-line treatment of metastatic bladder cancer by chemoimmunotherapy. However, upfront pembrolizumab, atezolizumab and durvalumab association with standard of care chemotherapy did not improve overall survival when compared to chemotherapy alone.We hereby highlight a study that was not included in this review, the INDUCOMAIN trial, by discussing its results and its future implications on immunotherapy for metastatic bladder cancer.

OBJECTIVES: To evaluate the efficacy and tolerability of paclitaxel and gemcitabine therapy after platinum-based chemotherapy for patients with advanced urothelial carcinoma. METHODS: Consecutive patients with advanced urothelial carcinoma who received paclitaxel and gemcitabine therapy from December 2003 to March 2018 were retrospectively reviewed. The objective response for paclitaxel and gemcitabine therapy, progression-free survival and overall survival, and adverse events were evaluated. The reduction rate among each metastatic site and the associations between the clinical parameters and overall survival or progression-free survival were also assessed. RESULTS: We enrolled 58 patients. Complete and partial responses were observed in two (3.4%) and 15 patients (26%), respectively. The median progression-free survival and overall survival were 4.3 months (95% confidence interval 2.9-5.2) and 11.5 months (95% confidence interval 7.7-14.8), respectively. The objective response rates of primary site and metastases in lymph nodes, lung, bone, and liver were 6.0%, 37%, 23%, 0%, and 22%, respectively. Poor performance status (≥1), prior use of gemcitabine and the number of metastatic sites (≥2) were significantly associated with poor overall survival. Although three patients discontinued the treatment because of adverse events, there was no therapy-related death. CONCLUSIONS: Paclitaxel and gemcitabine therapy seems to be a valid option as a subsequent treatment after platinum-based chemotherapy for urothelial carcinoma, especially in patients with favorable performance status and no prior use of gemcitabine.

BACKGROUND: Pembrolizumab is a new standard of care for patients with platinum-treated, metastatic urothelial carcinoma (UC). Nab-paclitaxel is active in advanced UC. In the PEANUT study (NCT03464734) we investigated their combination in advanced UC. PATIENTS AND METHODS: PEANUT was an open-label, single-arm, phase II trial that included patients who had failed one or two chemotherapy regimens, including platinum chemotherapy. Biomarker analyses focused on programmed cell-death ligand-1 combined positive score (CPS) and comprehensive genomic profiling on tumor samples and circulating tumor DNA. Patients received 200 mg pembrolizumab on day 1 (D1), and 125 mg/m2 nab-paclitaxel on D1 and D8, every 3 weeks, until disease progression or unacceptable toxicity. The primary end point was progression-free survival (PFS) according to RECIST (v1.1). The assumption was to detect an improvement in the median PFS from ≤3.0 months (H0) to ≥5.0 months (H1). RESULTS: Between January 2019 and January 2020, the PEANUT study enrolled 70 patients: 24% had failed two prior systemic therapies; 31% had an Eastern Cooperative Oncology Group (ECOG) performance status of 1; and 28.6% had liver metastases. After a median follow-up of 9.8 months, 40 patients have relapsed (57.1%). The median PFS was 5.9 months [95% confidence interval (CI) 3.1-11.5]. The confirmed objective response rate (ORR) was 38.6% (95% CI 27-51) with 17 partial responses and 10 complete responses (14.3%). The median duration of response was not reached. Five patients (7.1%) had ongoing responses lasting >12 months. The most common any-grade treatment-related adverse events included alopecia (71.4%), neutropenia (32.9%), and peripheral neuropathy (34.3%). Neither tumor mutational burden nor CPS was significantly associated with PFS at univariable analyses. The single-arm design of the trial was the major limitation. CONCLUSIONS: Pembrolizumab combined with nab-paclitaxel, as second- and third-line chemoimmunotherapy for metastatic UC, showed a favorable safety profile, durable PFS, and a clinically meaningful ORR in these preliminary analyses. This combination warrants additional randomized studies in earlier disease stages. CLINICALTRIALS. GOV NUMBER: ClinicalTrials.govNCT03464734; https://clinicaltrials.gov/ct2/show/NCT03464734.

PURPOSE: Immune-related adverse events (irAEs) have been associated with the efficacy of programmed cell death protein 1 (PD-1) inhibitors in patients with urothelial cancer. We therefore evaluated the relationship between irAEs and pembrolizumab efficacy in urothelial cancer patients. METHODS: Patients with urothelial cancer who were treated with pembrolizumab in a second-line setting or later between January 2018 and December 2018 were identified by reviewing their medical records from the Cancer Institute Hospital, Japanese Foundation for Cancer Research. Data were updated as of December 31, 2018. Kaplan-Meier curves for overall survival (OS) and time to treatment failure (TTF) according to irAE grade were evaluated using the log-rank test. Risk factors for exacerbation of irAEs were also evaluated with multivariate analysis. RESULTS: In this retrospective study, 43 patients received pembrolizumab. We identified irAEs in 22 of the 43 patients (51.2%), including 11 patients (25.6%) with grade 2 or 3 events. In patients with irAE grade 0 or 1, median TTF was 127 days, and median OS was 160 days according to the Kaplan-Meier method. On the other hand, in patients with irAE grade ≥2, median TTF and OS were not reached. Multivariate analysis also revealed that risk factors for exacerbation of irAEs (to grade ≥2) were positively associated with lymphocyte count at baseline (>2,000/µL) before pembrolizumab treatment (p = 0.021). CONCLUSIONS: Development of irAEs was associated with survival outcome of pembrolizumab treatment in patients with advanced urothelial cancer.

PURPOSE OF REVIEW: Advanced urothelial carcinoma (aUC) has long been treated preferably with cisplatin-based chemotherapy, but many patients are cisplatin-ineligible whereas for those who progress on a platinum-based regimen treatment options are limited. We review key recent data regarding immune checkpoint inhibitors that are changing this treatment landscape. RECENT FINDINGS: Since May 2016, five different agents targeting the PD-1/PD-L1 pathway (atezolizumab, pembrolizumab, nivolumab, avelumab, durvalumab) have received FDA approval for the treatment of aUC in the platinum-refractory setting, while pembrolizumab and atezolizumab are FDA-approved for cisplatin-ineligible patients in the first-line setting. Clinical outcomes and safety profiles of these agents appear relatively comparable across separate trials; however, only pembrolizumab is supported by level I evidence from a large randomized phase III trial showing overall survival benefit over conventional cytotoxic salvage chemotherapy in the platinum-refractory setting. Pembrolizumab has the highest level of evidence in platinum-refractory aUC, whereas pembrolizumab and atezolizumab have comparable level of evidence in the frontline setting in cisplatin-ineligible patients. Ongoing research is evaluating novel agents, various rational combinations, and sequences, as well as predictive and prognostic biomarkers.

BACKGROUND/AIM: Sequential therapy using chemotherapy and subsequent immune checkpoint inhibitor (ICI) treatment prolongs the survival of patients with advanced urothelial carcinoma (UC). However, no comparison data for oncological outcome between pembrolizumab and avelumab has been reported. Thus, we compared oncological outcomes between pembrolizumab as second-line therapy and maintenance avelumab therapy in patients with advanced UC. PATIENTS AND METHODS: We retrospectively evaluated patients with advanced UC treated with pembrolizumab or avelumab between January 2018 and February 2023. We compared oncological outcomes after adjusting for patient characteristics. Immune-related adverse events (AEs) in each group were evaluated using the Common Terminology Criteria for Adverse Events. RESULTS: There were 186 and 44 patients in the pembrolizumab- and avelumab-treated cohorts, respectively. After propensity score matching, 43 patients from each group were selected and analyzed. Median progression-free survival from the initiation of pembrolizumab and avelumab treatments was 126 and 139 days, respectively (log-rank test, p=0.625). Median overall survival in the pembrolizumab and avelumab cohorts were 658 days and not reached, respectively (log-rank test, p=0.249). Thirty-eight (20.4%) and 14 (31.8%) all-grade immune-related AEs were observed in 186 pembrolizumab- and 44 avelumab-treated patients, respectively (chi-squared test, p=0.112). Regarding endocrine-related AEs, 12 (6.5%) and none (0%) were observed in pembrolizumab- and avelumab-treated patients, respectively (Fisher's exact probability test, p=0.129). CONCLUSION: Pembrolizumab and maintenance avelumab therapy provide equivalent oncological outcomes in patients with advanced UC. Although no significant difference was observed, there might be a potential risk of higher endocrine-related AEs due to pembrolizumab compared to avelumab maintenance therapy.

Bladder cancer (BC) is the tenth most common malignancy globally. Urothelial carcinoma (UC) is a major type of BC, and advanced UC (aUC) is associated with poor clinical outcomes and limited survival rates. Current options for aUC treatment mainly include chemotherapy and immunotherapy. These options have moderate efficacy and modest impact on overall survival and thus highlight the need for novel therapeutic approaches. aUC patients harbor a high tumor mutation burden and abundant molecular alterations, which are the basis for targeted therapies. Erdafitinib is currently the only Food and Drug Administration (FDA)-approved targeted therapy for aUC. Many potential targeted therapeutics aiming at other molecular alterations are under investigation. This review summarizes the current understanding of molecular alterations associated with aUC targeted therapy. It also comprehensively discusses the related interventions for treatment in clinical research and the potential of using novel targeted drugs in combination therapy.
RESUMEN
PURPOSE: Post hoc analysis of the JAVELIN Bladder 100 trial of avelumab maintenance in locally advanced/metastatic urothelial carcinoma (la/mUC) to determine the interaction by programmed death ligand 1 (PD-L1) status for overall survival (OS), and additional analyses of survival per a different PD-L1 expression cutoff of ≥ 1% in tumor cells or immune cells (TC/IC). METHODS: JAVELIN Bladder 100 data were used for the analysis of the interaction by PD-L1 status (per cutoff used in the trial) for OS and, additionally, OS and progression-free survival (PFS) analyses per a different ≥ 1% TC/IC PD-L1 expression cutoff (Ventana SP263 assay). RESULTS: No significant interaction between treatment and PD-L1 status was observed for OS. Clinically meaningful and robust survival data were observed in favor of avelumab using the different ≥ 1% TC/IC PD-L1 expression cutoff. CONCLUSIONS: These results demonstrate the benefit of avelumab maintenance in la/mUC regardless of PD-L1 expression, consistent with approved labels.

Randomized phase III trial results have demonstrated enfortumab vedotin (EV), an antibody-drug conjugate (ADC) consisting of an anti-Nectin-4 human IgG1 monoclonal antibody and monomethyl auristatin E, is a useful treatment for patients with locally advanced or metastatic urothelial carcinoma (la/mUC) that progressed after immune checkpoint inhibitor (ICI) therapies. This multicenter retrospective cohort study aimed to identify predictive factors for the efficacy of EV therapy and prolonged overall survival (OS) of patients in clinical practice. This study included patients with la/mUC who received ICI treatment. Patients who subsequently received EV treatment, those who received non-EV chemotherapy, and those who received no treatment were defined as EV, non-EV, and best supportive care (BSC) groups, respectively. The median OS was 20, 15, and 7 months in the EV, non-EV, and BSC groups, respectively (p < 0.001). Patients with la/mUC who had a complete or partial response after EV treatment had a significantly prolonged OS compared with those with stable or progressive disease. Univariate analysis showed age, neutrophil-to-lymphocyte ratio (NLR), dysgeusia, and rash as independent predictors of OS improvement. NLR and dysgeusia were independent predictors of OS after EV in multivariate analysis. Patients without these factors had a significantly prolonged OS compared to those with both factors. In real-world practice, EV therapy is an effective treatment for patients with la/mUC after ICI treatment.
RESUMEN
Background and Objective: The prognosis of advanced urothelial carcinoma (aUC) is poor. To date, the gold standard of treatment for patients with aUC has been cisplatin-based chemotherapy. More recently, immune checkpoint inhibitors (ICIs) have been widely used for such patients, which has led to an improvement in their prognosis. In clinical practice, predicting the effectiveness of antitumor drugs or the prognosis of patients is important for making decisions on treatment strategies. Various parameters obtained from blood tests in the pre-ICI era have been adopted for patients in the ICI era. In this review, we summarize the parameters reflecting the status of aUC patients treated with ICIs based on current evidence. Methods: We conducted a literature search using PubMed and Google Scholar. The publications chosen were all peer-reviewed journals published over an unlimited time period. Key Content and Findings: Numerous inflammatory or nutritional parameters can be obtained from routine blood tests. These reflect malnutrition or systemic inflammation in patients with cancer. As in the pre-ICI era, these parameters are useful for predicting the effectiveness of ICIs and the prognosis of patients treated with ICIs. Conclusions: Various parameters are related to systemic inflammation and malnutrition, and are easily obtained from a routine blood test. Using these parameters from various studies as reference points is useful in making decisions on treatment for aUC.
RESUMEN
BACKGROUND: The phase 3 JAVELIN Bladder 100 trial showed significantly prolonged overall survival (OS) with avelumab first-line maintenanceâ¯+â¯best supportive care (BSC) vs. BSC alone in patients with advanced urothelial carcinoma (UC) that had not progressed with first-line platinum-containing chemotherapy. Here, efficacy and safety were assessed from the initial analysis of the JAVELIN Bladder 100 trial (data cutoff October 21, 2019) in patients enrolled in Asian countries. METHODS: Patients with locally advanced or metastatic UC that had not progressed with 4 to 6 cycles of first-line platinum-containing chemotherapy (gemcitabineâ¯+â¯cisplatin or carboplatin) were randomized 1:1 to receive avelumab first-line maintenanceâ¯+â¯BSC or BSC alone, stratified by best response to first-line chemotherapy and visceral vs. nonvisceral disease when initiating first-line chemotherapy. The primary endpoint was OS assessed from randomization in all patients and patients with PD-L1+ tumors (Ventana SP263 assay). Secondary endpoints included progression-free survival (PFS) and safety. RESULTS: A total of 147 patients in JAVELIN Bladder 100 were enrolled in Asian countries (Hong Kong, India, Japan, South Korea, and Taiwan). In this Asian subgroup, 73 and 74 patients received avelumabâ¯+â¯BSC or BSC alone, respectively. Median OS was 25.3 months (95% CI, 18.6 to not estimable [NE]) in the avelumabâ¯+â¯BSC arm vs. 18.7 months (95% CI, 12.8-NE) in the BSC alone arm (hazard ratio [HR], 0.74 [95% CI, 0.43-1.26]); median PFS was 5.6 months (95% CI, 2.0-7.5) vs. 1.9 months (95% CI, 1.9-1.9), respectively (HR, 0.58 [95% CI, 0.38-0.86]). In the avelumabâ¯+â¯BSC vs. BSC alone arms, grade ≥3 treatment-emergent adverse events (any causality) occurred in 44.4% vs. 16.2%, respectively. The most common grade ≥3 treatment-emergent adverse events in the avelumabâ¯+â¯BSC arm were anemia (9.7%), amylase increased (5.6%), and urinary tract infection (4.2%). CONCLUSIONS: Efficacy and safety results for avelumab first-line maintenance in the Asian subgroup of JAVELIN Bladder 100 were generally consistent with those in the overall trial population. These data support the use of avelumab first-line maintenance as standard of care for Asian patients with advanced UC that has not progressed with first-line platinum-containing chemotherapy.

Introduction: Metastatic urothelial carcinoma (mUC) has poor prognosis. A high unmet need exists for novel treatment for those who are unfit for platinum-based chemotherapy. Methods: We aimed to describe real-world temporal changes in patient characteristics and 1L treatment selection for mUC patients in the United States following the approval of anti-PD-1/L1 treatments. This study was a retrospective, observational study using anonymized and structured oncology electronic medical record (EMR) data from IQVIA and the US Oncology Network iKnowMed (USON). Results: After approval of 1L anti-PD-1/L1 treatment for mUC, there is a marked increase in the use of 1L anti-PD-1/L1 monotherapies, accompanied by a proportional decrease in 1L platinum-based treatments and non-guideline-based therapy; particularly among the elderly (> 75 years) and those with poor ECOG performance status (ECOG PS 2+). Discussion: Anti-PD-1/L1 monotherapies fulfill the prior unmet need of frail mUC patients who are ineligible for platinum-based therapies.
RESUMEN
Introduction: Advanced urothelial carcinoma remains aggressive and very hard to cure, while new treatments will pose a challenge for clinicians and healthcare funding policymakers alike. The U-CHANGE Project aimed to redesign the current model of care for advanced urothelial carcinoma patients to identify limitations ("as is" scenario) and recommend future actions ("to be" scenario). Methods: Twenty-three subject-matter experts, divided into three groups, analyzed the two scenarios as part of a multidimensional consensus process, developing statements for specific domains of the disease, and a simplified Delphi methodology was used to establish consensus among the experts. Results: Recommended actions included increasing awareness of the disease, increased training of healthcare professionals, improvement of screening strategies and care pathways, increased support for patients and caregivers and relevant recommendations from molecular tumor boards when comprehensive genomic profiling has to be provided for appropriate patient selection to ad hoc targeted therapies. Discussion: While the innovative new targeted agents have the potential to significantly alter the clinical approach to this highly aggressive disease, the U-CHANGE Project experience shows that the use of these new agents will require a radical shift in the entire model of care, implementing sustainable changes which anticipate the benefits of future treatments, capable of targeting the right patient with the right agent at different stages of the disease.
RESUMEN
BACKGROUND: In the treatment of advanced urothelial (aUC) and renal cell carcinoma (aRCC), biomarkers such as PD-1 and PD-L1 are not robust prognostic markers for immunotherapy (IO) response. Previously, a significant association between IO and a change in splenic volume (SV) was described for several tumour entities. To the best of our knowledge, this study presents the first correlation of SV to IO in aUC and aRCC. METHODS: All patients with aUC (05/2017-10/2021) and aRCC (01/2012-05/2022) treated with IO at our academic centre were included. SV was measured at baseline, 3 and 9 months after initiation of IO using an in-house developed convolutional neural network-based spleen segmentation method. Uni- and multivariate Cox regression models for overall survival (OS) and progression-free survival (PFS) were used. RESULTS: In total, 35 patients with aUC and 30 patients with aRCC were included in the analysis. Lower SV at the three-month follow-up was significantly associated with improved OS in the aRCC group. CONCLUSIONS: We describe a new, innovative artificial intelligence-based approach of a radiological surrogate marker for IO response in aUC and aRCC which presents a promising new predictive imaging marker. The data presented implicate improved OS with lower follow-up SV in patients with aRCC.
RESUMEN
INTRODUCTION: This large-scale, US-based study characterized real-world treatment patterns and clinical outcomes in patients with advanced or metastatic urothelial carcinoma (aUC). METHODS: This retrospective cohort analysis included patients with stage IV or node-positive aUC between January 1, 2011, and August 31, 2020, from an electronic health record-derived, de-identified database (Flatiron Health). Baseline characteristics and treatment patterns were assessed by first-line (1L) systemic treatment received and cisplatin eligibility status. Overall survival (OS) and progression-free survival (PFS) were evaluated. RESULTS: Of 8,183 patients included, 5,855 (71.6%) received systemic 1L therapy and 2,328 (28.4%) did not. Median (range) follow-up from aUC diagnosis was 9.7 (0.2-116.6) months. Of patients who received 1L systemic therapy, 30.1% were cisplatin-eligible, 39.2% were cisplatin-ineligible, 10.5% did not receive cisplatin despite qualifying ECOG PS and renal function, and cisplatin eligibility was unknown in 20.2%. Of those treated, 74.8% received 1L chemotherapy and 23.0% received 1L immuno-oncology-based monotherapy. Median OS (95% CI) was 14.5 (14.0-15.2) months in patients who received 1L systemic therapy and 6.8 (6.2-7.3) months in those who did not. Of those treated, cisplatin-ineligible patients had worse OS and PFS outcomes vs. other subgroups. Among cisplatin-ineligible patients, 1L immuno-oncology monotherapy (nâ¯=â¯865) was associated with worse OS and PFS outcomes than 1L chemotherapy (nâ¯=â¯1,369). CONCLUSIONS: More than 25% of aUC patients did not receive 1L systemic therapy; of patients who were treated, most received chemotherapy, with less than 25% receiving immuno-oncology-based monotherapy. Overall, these results highlight the substantial unmet need in this population, specifically among cisplatin-ineligible patients.

BACKGROUND/AIM: The optimal timing of switching from platinum-based chemotherapy to pembrolizumab in patients with advanced urothelial carcinoma (UC) remains unclear. PATIENTS AND METHODS: Thirty-four patients who received pembrolizumab as second-line treatment after first-line platinum-based chemotherapy were retrospectively evaluated. RESULTS: According to overall survival (OS) from pembrolizumab, there was a significant difference between ≤4 and >4 prior chemotherapy cycles (7.0 and 25.5 months, p=0.034), but not between ≤6 and >6 cycles (11.3 and 6.6 months, p=0.658). According to the Cox proportional hazards regression model, the number of chemotherapy cycles was not correlated with better OS in pembrolizumab-treated patients. According to the OS from the first-line treatment, there was a significant difference between ≤4 and >4 prior chemotherapy cycles (17.3 and 37.1 months, p<0.001), but not between ≤6 and >6 cycles (18.6 and 27.3 months, p=0.276). CONCLUSION: The optimal timing of switching from platinum-base chemotherapy to pembrolizumab in advanced UC is around six cycles.
