摘要

•The proposed MSDA framework can promote LN metastasis prediction in multi-center learning.•A novel 3D IFPN can effectively extract the domain invariant features of small targets (i.e., LNs).•A novel UDS-GCN is designed to achieves the imbalanced knowledge transfer and class-aware feature alignment across domains.
