Abstract
Objective:This study aims to determine the role of beetroot extract in overcoming the chemoresistance of Neoadjuvant Adriamycin Cyclophosphamide (NAC) regimens with a target immune response in the tumour microenvironment at the pre-clinical stage. Methods:This study was conducted on rats with 7,12-Dimethyl Benz (α) Anthracene (DMBA) induced mammary adenocarcinoma. Adriamycin Cyclophosphamide was given in 4 cycles, whereas beetroot extract was administered three times each cycle. Observations of CD8 T cells and Myeloid Derivative Suppressive Cells (MDSC) expression levels and pathological responses were carried out on tumour tissue taken at the end of the observation. Results:Supplementation of beetroot extract to NAC could significantly increase CD8 T cells and decrease MDSC in the tumour microenvironment. The addition of beetroot extract gave a better pathological response. Conclusion:Beetroot extract enhances the immune response in the tumor microenvironment so that it has the potential to overcome chemoresistance in NAC.
