Role of Probiotics in Enhancing Immune Function and Improving the Effectiveness of Treatments for Pancreatic Cancer

Pancreatic cancer often goes undetected in its early stages due to minimal or no symptoms, leading to late diagnosis with limited treatment options. Challenges include late detection, drug resistance, and the tumor's complexity, but advances are being made in targeted therapies, immunotherapy, metabolism-based strategies, and early detection techniques. Current treatments focus on boosting immune responses, improving survival rates, and enhancing patients' quality of life. Immunotherapy has sparked interest in cell-based approaches, with studies showing that natural killer (NK) cells can eliminate pancreatic tumor stem-like cells and promote tumor differentiation through cytokines. NK cells play a key role in tumor destruction, though reduced cytotoxic activity has been observed in NK cells from pancreatic cancer patients’ blood. Probiotics are being investigated as potential aids in pancreatic cancer therapy to restore immune function, inhibit tumor growth, and improve treatment outcomes. By activating immune cells like PBMCs, NK cells, T cells, and antigen-presenting cells, probiotics can help combat pancreatic tumors. They also enhance NK cell-based immunotherapies and improve the effectiveness of immunotherapy, radiation, and chemotherapy. Combining probiotics with NK cell therapy has shown promise in reducing tumor burden, restoring immune function, and reversing tumor-induced bone damage in pancreatic cancer models, offering hope for future treatments.
