Colorectal Cancer Real-world Outcomes Study of Survival With Immunomodulator Plus Standard Anti-cancer Therapies

Colorectal cancer (CRC) is the third most common cancer worldwide. Despite the availability of numerous standard therapies for CRC, clinical outcomes from these treatments remain unsatisfactory. The tumor microenvironment (TME) plays an important role to regulate tumor growth, progression, and metastasis and can limit the efficacy of cancer therapies. Therefore, targeting TME would be an efficient approach for cancer treatment. Astragalus polysaccharide (APS) Injection is an immunomodulator, which can enhance anti-tumor efficacy through regulation of TME. This drug has been approved as a prescription drug for alleviating cancer-related fatigue by the Taiwan Food and Drug Administration (TFDA). In this real-world study, clinical data will be collected both retrospectively and prospectively from the medical records of CRC patients undergoing anti-cancer treatment who did or did not receive immunomodulators. It can be used to understand the possible clinical benefit of immunomodulator plus anti-cancer therapies for patients with CRC, and physicians can refer to these results to give patients the suitable treatment recommendations.
