## Summary

A team of researchers presented PathLUPI, a new framework that incorporates transcriptomic privileged information during training to create genome‑anchored embeddings for whole‑slide images (WSIs). At inference, the model relies only on routine pathology slides, yet it captures molecular context that improves prediction of complex biomarkers and patient outcomes.\n\nThe method was tested on 49 molecular oncology tasks covering 11,361 cases from 20 independent cohorts. PathLUPI achieved an area under the ROC curve of at least 0.80 on 18 biomarker and molecular subtyping tasks and a concordance index of at least 0.70 across survival cohorts spanning five major cancer types. Analysis of the embeddings revealed distinct cellular morphological signatures linked to specific genotypes, a finding that was corroborated using high‑resolution spatial transcriptomics samples. The work was funded by several Chinese national and regional research programs.\n\nThese results suggest that embedding molecular information into histology representations can bridge the gap between costly genomic testing and everyday pathology workflows, potentially expanding access to precision oncology.

## Key points

- PathLUPI trains genome‑anchored histology embeddings using transcriptomic privileged information, enabling WSI‑only inference.
- Evaluated on 49 tasks, 11,361 cases from 20 cohorts, achieving AUC ≥0.80 on 18 biomarkers and C‑index ≥0.70 on five cancer survival cohorts.
- Embeddings expose genotype‑linked morphological patterns confirmed by high‑resolution spatial transcriptomics.

## Why it matters

Linking molecular data to routine pathology images could cut sequencing costs, speed up precision oncology decisions, and broaden molecular diagnostic access.
