The potential biomarkers in predicting pathologic response of breast cancer to three different chemotherapy regimens: a case control study.

For example, only one of total twenty six ER-positive tumors achieved major pathologic response by treatment of EFC regimen (pRR = 3.7%), and in six of thirty ER-positive tumors in DEC group achieved pathologic response (pRR = 20%), although the difference did not reach statistical significance ( p = 0.105).
