1 · What the graph read from it

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.

2 · The registry

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

Human epidermal growth factor receptor 2 (HER2) has emerged as a crucial biomarker across various cancers, shaping therapeutic strategies and prognostic evaluations. In urothelial carcinoma, HER2 positivity rates can reach up to 68% when HER2-low tumours (immunohistochemistry 1+) are included in the analysis. HER2 overexpression and ERBB2 genomic alterations have been linked to advanced disease stages and poor outcomes in urothelial carcinoma. Emerging evidence suggests that HER2-low tumours might be a distinct and actionable subgroup. Accurate and consistent assessment of HER2 status is increasingly vital to identify patients likely to benefit from HER2-targeted therapies, raising interest in refining thresholds for HER2 expression, aiming to predict treatment response. HER2 heterogeneity across stages and histological subtypes complicates its evaluation, with definitions of HER2 positivity differing between clinical trials and treatments. In urothelial carcinoma, HER2-targeted therapies, such as tyrosine kinase inhibitors, monoclonal antibodies and antibody-drug conjugate (ADCs) have been explored. Unlike tyrosine kinase inhibitors and monoclonal antibodies, which act through HER2-related pathways, ADCs use HER2 as a target but achieve efficacy through additional mechanisms, enabling their activity even at low HER2 expression levels. Trastuzumab deruxtecan, a novel anti-HER2 ADC, has received FDA tumour-agnostic approval for unresectable or metastatic HER2+ solid tumours, including urothelial carcinoma, after prior therapies. Interactions between HER2 protein and putative biomarkers such as EGFR, NECTIN4, PDL1 and FGFR3 genomic alterations might influence therapeutic outcomes, offering opportunities for improved patient selection and innovative combination strategies.
