Tumor–Immune Dynamics in Peripheral Blood: Sustained Presence of Stemness-Associated Circulating Tumor Cells During Chemotherapy in Gastric Cancer
Background: Circulatin Tumor Cells (CTCs) are promising indicators for gastric cancer tumour dynamics and therapy response. Epithelial and stemness-related gene expression can be detected with great sensitivity using RT-qPCR. This study measured EpCAM (CD326), CD44, CD133, and CK19 in gastric cancer patients' periphera...
