Abstract
Collaboration between medical science liaisons (MSLs) and advanced practice providers (APPs) is essential for advancing oncology care in an increasingly complex treatment landscape. Medical science liaisons serve as scientific resources, engaging in non-promotional exchange, delivering tailored education, supporting clinical research, and gathering real-world insights. These interactions help APPs stay current with evolving standards of care, interpret clinical trial data, and address knowledge gaps, while APPs provide perspectives that inform medical strategy and research priorities. This article outlines the origins and responsibilities of the MSL role, clarifies distinctions from commercial functions, and explores key pillars of collaboration: clinical research, medical education, and insight gathering. Through practical examples, it demonstrates how effective partnerships between MSLs and APPs bridge the gap between scientific innovation and clinical application, ultimately improving patient outcomes.
