Lubner, Sam J.

The traditional combined hematology and oncology fellowship model is increasingly strained by accelerating subspecialization and therapeutic complexity. This commentary focuses on structural reforms within fellowship training to better align education with contemporary clinical practice and evolving workforce demands. We propose standardized, career-aligned tracks, earlier subspecialty focus within fellowship, and redesigned continuity clinic models that preserve foundational breadth while enabling depth of expertise. We further highlight how emerging assessment reforms and educational tools can support these structural changes. By aligning fellowship training with both real-world clinical demands and established educational science, we can ensure a more sustainable and effective pathway for preparing future hematologists and oncologists.
