A recent research paper published on arXiv has uncovered significant data leakage issues within multimodal benchmarks used for whole-slide image (WSI) analysis in computational pathology. The study found that patient-level and institutional-level data contamination is prevalent, with overlaps ranging from 92.3% to 100% in TCGA-derived benchmarks. This leakage compromises the evaluation of vision-language models (VLMs), making it difficult to distinguish genuine multimodal reasoning from memorization of artifacts. The researchers propose concrete recommendations for creating contamination-free evaluations to ensure verifiable progress in the field. AI
