Keith Miskimins, PhD, Sanford/USD Medical Center/Sanford Research (Sioux Falls), is performing a study that uses metformin to reduce cardiac toxicity in breast cancer patients. The objective of the study is to determine if co-administration of the medications metformin and doxorubicin in breast cancer patients receiving adjuvant therapy will reduce the number of patients who develop a significant change in left ventricular ejection fraction (LVEF). He'll also discuss a new grant he's received to further his study.
