The Most recent updates on pectin in Cancer therapy: A review

Pectin is a structurally diverse, plant-derived polysaccharide primarily obtained from apple pomace and citrus fruits. Its biocompatibility, modifiability, and multiple bioactivities have attracted increasing interest for potential applications in cancer therapy. This review summarizes modification techniques that enhance pectin's physicochemical and biological properties, elucidates its main anticancer mechanisms, and highlights recent advances (2020-2025) in its therapeutic potential. Physical, chemical, enzymatic, and combined modification strategies are described, followed by an overview of pectin's anticancer actions, including immunomodulation, induction of apoptosis, inhibition of proliferation and metastasis, suppression of angiogenesis, and galectin-3 inhibition. Recent preclinical and early clinical findings are presented, with emphasis on modified citrus pectin (MCP). Modified pectins, particularly MCP, demonstrate enhanced bioavailability and potent anticancer activity. MCP exhibits synergistic effects with chemotherapeutic agents such as oxaliplatin, reducing tumor burden and alleviating chemotherapy-induced peripheral neuropathy. Evidence from in vitro, in vivo, and limited clinical studies supports its role as an effective adjunct in oncology. Pectin represents a promising, safe, and versatile natural compound for cancer therapy. The compiled recent data provide a foundation for further research aimed at clinical translation and optimized therapeutic applications.
