Inflammatory bowel disease (IBD), comprising ulcerative colitis (UC) and Crohn's disease (CD), is a chronic inflammation of the gut characterized by an imbalance in the intestinal microbiome and ecology. IBD raises the risk of developing colorectal cancer (CRC). CRC is one of the most commonly diagnosed cancers in the world, with high incidence rates. Extracellular vesicles (EVs) play a crucial role in intercellular communication and are vital for maintaining intestinal homeostasis. Recent research highlights novel inflammatory mediators, such as specialized pro-resolving mediators (SPMs), damage-associated molecular patterns (DAMPs), alarmins, non-coding RNAs (ncRNAs), and metabolic intermediates, as crucial in the pathophysiology of IBD and CRC. These novel inflammatory mediators are transported by EVs, influencing the pathogenesis of IBD and associated CRC. Therefore, this article examines the role of novel inflammatory mediators transported by EVs in the pathogenesis of IBD and related CRC, as well as the interaction between EVs and the tumor microenvironment. We also review new research on EV use as a diagnostic indicator and on the potential of EVs, such as mesenchymal stem cell-derived EVs (MSC-EVs), as therapeutic delivery channels for cancer treatment targeting unique inflammatory mediators.
