Predicting Therapeutic Response to Antibody-Drug Conjugates Using Targeted PET Imaging: A Systematic Review.
Review in Cancers, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAntibody-drug conjugates (ADCs) are gaining rapidly expanding clinical utility, with a growing number of approved indications across compounds that differ in target antigen, payload mechanism, and linker design. However, treatment response remains heterogeneous, and predictive biomarkers to identify patients most likely to benefit are limited. Given that ADC efficacy depends on sufficient target antigen expression and distribution across tumor lesions, positron emission tomography (PET) imaging offers a unique opportunity to non-invasively assess whole-body target availability. We therefore conducted a systematic literature review to evaluate the relationship between PET-measured tumor antigen expression and the therapeutic response to ADCs targeting the same antigen.
methodA systematic comprehensive search of PubMed, EMBASE and Web of Science databases was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, using terms related to targeted PET, ADC treatment and response assessment. Article screening, eligibility assessment, and data extraction were performed independently using predefined criteria by two reviewers. Disagreements were resolved by consensus.
resultsA total of 5628 records were identified. After removing duplicates, 4323 records were screened by title and abstract. Fifty-eight underwent full-text review and seven were included in the final review. Four trials investigated human epidermal growth factor receptor 2 (HER2)-targeted therapy, one Nectin-4, one mesothelin and one STEAP1. In all HER2- and Nectin-4-related trials, patients with a higher uptake on targeted PET had a higher probability of responding to targeted treatment. Included trials were generally small and had a moderate risk of bias.
conclusionTargeted PET imaging showed potential to predict treatment response in trials evaluating clinically active agents. Additional clinical trials across a broader range of targets, along with standardized acquisition protocols and harmonized study designs, are needed to enable the integration of this technique into clinical practice and ultimately translate its benefits to patients.
