BACKGROUND: Immune checkpoint inhibitors are an important therapeutic option for urothelial carcinoma, but durable responses are achieved in a minority of patients. Identifying pre-treatment biomarkers that may predict response to these therapies or who exhibit intrinsic resistance, is of paramount importance. OBJECTIVE: To explore the prevalence of PD-L1 copy number alteration in urothelial carcinoma and correlate with response to immune checkpoint inhibitors. METHODS: We analyzed a cohort of 1050 carcinomas of the bladder and upper urinary tract that underwent targeted next generation sequencing, prospectively. We assessed PD-L1 protein expression, copy number status (next generation sequencing/FISH), and detailed treatment response. RESULTS: We identified 9 tumors with PD-L1 amplification and 9 tumors with PD-L1 deletion. PD-L1 protein expression was the highest in PD-L1 amplified tumors. Of the 9 patients whose tumors harbored PD-L1 amplification, 6 received immunotherapy with 4 deriving clinical benefit, and two achieving durable response. Of the 9 patients whose tumors had PD-L1 copy number losses, 4 received immunotherapy with 3 experiencing disease progression. CONCLUSIONS: PD-L1 copy number alterations may serve as potential biomarkers of response to immunotherapy in urothelial carcinoma patients, if validated in larger cohorts.

Immune checkpoint inhibitors have revolutionised cancer therapy in the past decade. Although they have been indicated to treat a diverse range of malignant neoplasms, they are also associated with various immune-related adverse effects. We report the case of a 74-year-old man with a history of urothelial carcinoma who had atezolizumab-induced myocarditis and myositis resulting in acute hypercapnic respiratory failure, despite the discontinuation of atezolizumab and aggressive treatment with corticosteroids. This case highlights the importance of a multidisciplinary approach for early diagnosis and treatment of immune-related adverse events. Physicians must be aware of the risks associated with immune checkpoint inhibitors and have a basic knowledge regarding their management.

476 Background: Reliable predictive markers are lacking in patients (pts) with locally advanced or metastatic urothelial carcinoma (aUC) treated with immune checkpoint inhibitors (ICI). We sought to determine whether specific genomic alterations could be used to predict overall survival (OS) in this patient population. Methods: We undertook a retrospective cohort study of pts with aUC who received ICI and underwent genomic profiling by next-generation sequencing (NGS). All patients underwent NGS using commercially available platforms (e.g. Foundation Medicine, Strata, Invitae), or testing on the CLIA-certified institutional panel UCSF500. Associations between the 20 most frequently altered genes and OS were first examined by Cox regression. Genes with a p <0.1 on univariate analysis and relevant clinical variables were then included in a multivariable analysis. Results: We identified 78 pts treated with ICI for aUC with available genomic profiling results. Median age at ICI initiation was 71; the majority of patients had visceral metastases (70.5%), ECOG performance status ≤1 (62.8%) and received ICI in the post-platinum setting (52.6%). Objective response rate in this cohort was 35.9%, median progression free survival was 4.0 months (95% CI 2.6-10.5) and median OS was 17.5 months (95% CI 14.1-NR) from ICI start. The most commonly altered genes were the TERT promoter (TERTp) (61%), TP53 (52%), RB1 (31%), CDKN2A(29%) and CDKN2B (27%). On univariable analysis there was a trend towards longer OS in pts with TERTp mutations (HR 0.53, 95% CI 0.27-1.06, p = 0.07), and shorter OS in pts with CDKN2B mutations (HR 1.91, 95% CI 0.98-3.73, p = 0.06). Both mutations were included in a multivariable analysis. After adjusting for known prognostic variables (ECOG PS, visceral metastases, albumin, hemoglobin, body mass index [BMI], neutrophil to lymphocyte ratio [NLR], and histology), the presence of a TERTp mutation was significantly associated with improved OS (HR 0.30, 95% CI 0.10-0.93, p = 0.04; Table). Conclusions: The presence of a TERTp mutation was an independent predictor of improved OS in a cohort of aUC pts treated with ICI. Other common mutations and clinical variables were not associated with OS on a multivariable analysis. These findings are hypothesis-generating and prospective validation is needed.

Bladder cancer is the seventh most frequent cancer worldwide. The majority of patients present with nonmuscle invasive disease, while 20% of the patients are diagnosed with muscle-invasive bladder cancer. The treatment of nonmuscle invasive disease is endoscopic resection followed by intravesical adjuvant treatment for high risk patients. The standard treatment of localized muscle-invasive disease is neoadjuvant chemotherapy followed by radical cystectomy. Platinum-based chemotherapy is the first-line treatment in locally advanced or metastatic urothelial carcinoma. Immune checkpoint inhibitors have been approved for the treatment of metastatic urothelial carcinoma as second-line treatment or first-line in platinum-ineligible patients. Recently, pembrolizumab have been approved in BCG-refractory nonmuscle invasive bladder cancer. This review summarizes the current evidence concerning immunotherapy in the treatment of urothelial carcinoma.

Abstract Background: Immune checkpoint inhibitors (ICIs) have become important tools for the treatment of advanced urothelial carcinoma (aUC). However, the clinical strategy using ICIs and chemotherapy is still controversy. The aim of this study was to evaluate the association of clinical parameters in aUC patients with ICIs treatment.Methods: We retrospectively analyzed aUC patients who received atezolizumab and pembrolizumab between January 2015 and October 2020. The associations between baseline demographics and clinical outcomes were evaluated.Results: Of the 74 included patients, the median age was 67 years. Among them, 53 patients received atezolizumab and the other 21 received pembrolizumab. There were 50 patients receiving first line ICIs therapy and the other 24 received second line monotherapy. Fifty-two (83.87%, 52/62) received cisplatin among all chemotherapy patients. The median progression free survival was 10.94 months and the overall survival was 28.44 months. Poor chemotherapy response or no chemotherapy, liver metastases, Eastern Cooperative Oncology Group (ECOG) status and higher neutrophil/lymphocyte ratio (NLR) were associated with higher risk of diseases progression (HR=5.70, 95% CI 2.04-15.90, p=0.001, HR=6.08, 95% CI 1.79-20.57, p=0.004; HR=5.40, 95% CI 1.76-16.57, p=0.003; HR=6.08, 95% CI 2.56-14.44, p<0.001 and HR= 1.02, 95% CI 1.01-1.03, P=0.002 respectively). Liver metastases and WBC before ICI were associated with increased death risk (HR=11.95, 95%CI 3.22-44.34, p<0.001; HR=1.0001, 95% CI 1.00001-1.00002, p=0.036 respectively) while ICI response was associated with decreased death (HR=0.22, 95%CI 0.08-0.62, p=0.004). Chemotherapy responders were associated with better ICI treatment response (OR=6.52, 95%CI 1.45-29.24, p=0.014) while lymph node metastases and poor ECOG was associated with poor ICI response (OR=0.31, 95%CI 0.10-0.94, p=0.038; OR=0.32, 95%CI 0.11-0.95, p=0.040).Conclusions: Our data showed predictive role of first-line chemotherapy response to ICIs treatment efficacy in aUC patients as well as other prognostic factors, such as ECOG status, serum white blood cell count or NLR and liver metastases.
