Abstract
Urothelial carcinoma (UC) with deficient mismatch repair (dMMR) is a specific subtype of UC characterized by the loss of mismatch repair (MMR) proteins and its association with Lynch syndrome (LS). However, comprehensive real-world data on the incidence, clinicopathological characteristics, molecular landscape, and biomarker landscape for predicting the efficacy of PD-1/PD-L1 inhibitors in the Chinese patients with dMMR UC remains unknown. We analyzed 374 patients with bladder urothelial carcinoma (BUC) and 232 patients with upper tract urothelial carcinoma (UTUC) using tissue microarrays, immunohistochemistry, and targeted next-generation sequencing. Results showed the incidence of dMMR UC was higher in the upper urinary tract than in the bladder. Genomic analysis identified frequent mutations in KMT2D and KMT2C genes and LS was confirmed in 53.8% of dMMR UC cases. dMMR UC cases displayed microsatellite instability-high (MSI-H) (PCR method) in 91.7% and tumor mutational burden-high (TMB-H) in 40% of cases. The density of intratumoral CD8+ T cells correlated with better overall survival in dMMR UC patients. Positive PD-L1 expression was found in 20% cases, but some patients positively responded to immunotherapy despite negative PD-L1 expression. Our findings provide valuable insights into the characteristics of dMMR UC in the Chinese population and highlights the relevance of genetic testing and immunotherapy biomarkers for treatment decisions.

Abstract
PURPOSE OF REVIEW To discuss recent advances in the treatment of advanced urothelial carcinoma (UC) and how best to incorporate new therapies into clinical practice. RECENT FINDINGS There have been several recent practice-changing phase 2 and 3 trials of immune checkpoint inhibitors (ICIs), antibody-drug conjugates (ADCs), and targeted agents in advanced UC. Based on data from these trials, ICIs can be used as first-line maintenance therapy in patients who do not progress on platinum-based chemotherapy, second-line therapy for those with progression, and first-line therapy in cisplatin-ineligible patients with PD-L1 expression; ADCs and targeted agents provide later-line treatment options. Despite substantial progress in the treatment of advanced UC, there are still many uncertainties, including the optimal treatment sequence for novel agents, and reliable predictive biomarkers to aid in treatment selection. There is also an unmet need for effective treatment options in patients unfit for any platinum-based chemotherapy.

Management of Advanced Urothelial Carcinoma in Older and Frail Patients: Have Novel Treatment Approaches Improved Their Care? Drugs Aging 2022; 39:271-284. [PMID: 35344197 DOI: 10.1007/s40266-022-00933-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/11/2022] [Indexed: 11/03/2022]
Abstract
Patients with urothelial carcinoma tend to be older and frailer with a large number of chronic medical conditions. This is particularly pronounced in those with unresectable locally advanced and metastatic urothelial carcinoma. Prior to 2016, treatment options in advanced urothelial carcinoma were limited to chemotherapy, and as a result, a large number of patients were not receiving disease-directed management. Over the last 6 years, multiple alternative modalities including immune checkpoint inhibitors and targeted therapies have been introduced. They are being utilized clinically in older and frail patients, but there are limited studies investigating outcomes in these specific populations. Based upon current evidence, age does not impact the efficacy and tolerance of immune checkpoint inhibitors if patients are fit enough to receive therapy. In frailer patients, immune checkpoint inhibitors appear to be safe, but outcomes from largely retrospective studies demonstrate mixed data regarding their efficacy. Although there are indications from clinical trials that enfortumab vedotin, sacituzumab govitecan, and erdafitinib are also efficacious irrespective of age, there is still not enough evidence to draw definitive conclusions about their use in older and frail patients. Regardless, in all older patients with advanced urothelial carcinoma, it is critical to evaluate for frailty through geriatric screening tools and comprehensive assessments. Combining these evaluations with consideration of an individual patient's goals should be the foundation upon which therapeutic decisions are made in this population of patients.
