Colon cancer is a leading cause of cancer-related morbidity and mortality worldwide, necessitating advancements in therapeutic strategies to improve outcomes. Current treatment modalities, including surgery, chemotherapy, and radiation, are limited by systemic toxicity, low drug utilization rates, and off-target effects. Colon-targeted drug delivery systems (CDDS) offer a promising alternative by leveraging the colon's unique physiology, such as near-neutral pH and extended transit time, to achieve localized and controlled drug release. Polysaccharide-based CDDS, utilizing natural polymers like chitosan, cyclodextrin, pectin, guar gum, alginate, hyaluronic acid, dextran, chondroitin sulfate, and inulin, have emerged as innovative approaches for improving the specificity and efficacy of colon cancer treatments. These biocompatible and biodegradable polymers enable site-specific drug delivery, enhance tumor apoptosis, reduce systemic side effects, and improve patient compliance. This review evaluates recent advancements in polysaccharide-based CDDS, detailing their drug release mechanisms, therapeutic potential, and challenges in overcoming gastrointestinal transit and pH variability. Studies highlight the successful formulation of nanoparticles, microspheres, and other delivery systems, demonstrating targeted drug delivery, improved bioavailability, and enhanced cytotoxicity against colon cancer cells in-vitro and in-vivo. The review underscores the need for continued research on polysaccharide-based CDDS for colon cancer treatment, offering a path toward more effective, patient-centered oncological care.
