Organoids in lung cancer brain metastasis: Foundational research, clinical translation, and prospective outlooks

Abstract

Brain metastasis stands as a leading contributor to mortality in lung cancer patients, yet the intricate mechanism underlying this phenomenon remains elusive. This underscores the need for robust preclinical models and effective treatment strategies. Emerging as viable in vitro models that closely replicate actual tumors, three-dimensional culture systems, particularly organoids derived from non-malignant cells or cancer organoids, have emerged as promising avenues. This review delves into the forefronts of fundamental research and clinical applications focused on lung cancer brain metastasis-derived organoids, highlighting current challenges and delineating prospects. These studies offer tremendous potential for clinical application despite being in nascent status.
