Researchers have developed ASTRA, a new framework designed to unify fragmented representations from various pathology foundation models into a cohesive slide-level understanding. This system semantically grounds these representations using structured pathology annotations like cancer type and anatomic site. ASTRA utilizes a combination of sparse mixture-of-experts contextualization, masked multi-model reconstruction, and contrastive alignment to achieve high accuracy in pan-cancer classification and text-guided tumor localization.
