The present invention relates to a method for predicting the usefulness of chemotherapy for breast cancer patients, and more particularly, to measure the expression levels of a gene for predicting breast cancer prognosis and a standardized gene in a biological sample obtained from the breast cancer patient. In addition, the present invention relates to a method of predicting by standardizing, separately, a group of patients having a large usefulness of chemotherapy and a group of patients having a small usefulness. The method of the present invention has the effect of accurately predicting the usefulness of chemotherapy for breast cancer patients, and can be effectively used for the purpose of providing a clue as to the future direction of breast cancer treatment.
