Clinical Outcomes of Treatment With Immunomodulator Plus Standard Anti-cancer Therapies for Patients With Colorectal Cancer: A Retrospective Study

Colorectal cancer (CRC) is the third most common cancer worldwide. The clinical outcomes from CRC treatments are often unsatisfactory for the majority of patients. 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 could provide an efficient approach for cancer treatment.

Astragalus Polysaccharide Injection, an immunomodulator, which can stimulate medullary hematopoiesis and enhance immune function. It also can modulate TME. Astragalus Polysaccharide Injection has been approved as a prescription drug for alleviating cancer-related fatigue by the Taiwan Food and Drug Administration (TFDA).

In this retrospective study, we will collect clinical data and survival status of colorectal cancer patients undergoing anti-cancer treatment from their medical records with and without immunomodulator, Astragalus polysaccharide Injection. It can be used to understand the possible clinical benefit of immunomodulator plus anti-cancer therapies for patients with colorectal cancer, and physicians can refer to these results to give patients the suitable treatment recommendations.
