Core Tip: In recent years, cancer stem cells (CSCs) have become an extremely important subject in cancer biology. CSCs are considered to be a very small component of tumor tissues, which nevertheless have the capacity for self-renewal, differentiation, and epithelial–mesenchymal transition. CSCs can also explain the clinical phenomenon of resistance to chemotherapy or radiotherapy. Many studies have also found that CSCs are important for cancer initiation and metastasis and play a key role in cancer recurrence. Here, we review GCSC (gastric cancer stem cell)-targeting therapies in GC, including information on GCSC-surface/intracellular markers and GCSC-mediated pathways. This review also provides a brief description of the GCSC niche. Understanding the molecular mechanism of GCSC-targeting agents can help optimize the accuracy of diagnosis and prognosis and the selection of the most appropriate therapy for GC patients.
