This research presents a detailed spatial transcriptomic atlas of small cell lung cancer (SCLC) to identify how the tumor microenvironment evolves during lymph node metastasis. By examining over 600,000 individual cells from 75 patients, the study identifies three specific malignant subclusters that appear during metastasis and exhibit unique metabolic and immune-evading properties. The authors describe a dynamic vascular-immune crosstalk, noting that immune cells within the vascular niche are functionally reprogrammed to become more cytotoxic as the disease spreads. Through cellular…
