Predictors of Response and Mechanisms of Resistance to Antibody Drug Conjugates in Urothelial Carcinoma.
Review in Current oncology (Toronto, Ont.), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Antibody-drug conjugates (ADCs) have reshaped the treatment landscape of urothelial carcinoma (UC) by enabling selective delivery of highly potent cytotoxic agents to tumor cells. Enfortumab vedotin, sacituzumab govitecan, and HER2-directed ADCs have demonstrated meaningful clinical activity across metastatic and earlier disease settings, with enfortumab vedotin plus pembrolizumab now established as a first-line standard of care. Despite these advances, therapeutic responses remain heterogeneous, and resistance frequently limits durability. This review summarizes current knowledge on predictors of response and mechanisms of resistance to ADCs in UC, highlighting the roles of target antigen expression and heterogeneity, genomic alterations, payload sensitivity, drug efflux transporters, and tumor microenvironmental factors. We discuss emerging biomarkers beyond antigen abundance, patterns of cross-resistance and treatment sequencing, and evolving strategies to overcome resistance, including next-generation ADC design and rational combination therapies. Advancing biomarker-driven patient selection and addressing mechanisms of resistance will be critical to maximizing the durability and clinical impact of ADCs in urothelial carcinoma.
