Colorectal cancer (CRC), one of the most common malignancies of the digestive system, is characterized by complex pathogenic mechanisms and an overall poor prognosis. The gut microbiota and its metabolites play a dual role in CRC by modulating various forms of programmed cell death (PCD), either promoting or inhibiting tumorigenesis and influencing the tumor responses to chemotherapy and immunotherapy. This review systematically summarizes recent advances in understanding how the gut microbiota regulates CRC initiation, progression, and responses to therapies through the modulation of apoptosis, autophagy, ferroptosis, and pyroptosis. Furthermore, it discusses the potential clinical-translational implications of these findings, aiming to provide a theoretical foundation for elucidating CRC pathogenesis and developing novel therapeutic strategies targeting the gut microbiota.
