Current Research

Dr. Lois Shepherd of the NCIC Clinical Trials Group in Ontario, Canada and Dr. Pamela Goodwin have teamed up to conduct a randomized phase III trial of the effect of the anti-diabetes drug, metformin, on recurrence and survival in early stage breast cancer. Metformin is a very old drug which is used in the treatment of adult-onset diabetes. Over the last decade there has been a growing body of evidence to suggest that high levels of insulin resulting from diabetes may play a role in the development and recurrence of many cancers including breast cancer. Metformin acts to inhibit the insulin pathway and its potential use in preventing the recurrence of early stage breast cancer is being explored in the MA.32 study. Early results from the study, which is being conducted across North America, the United Kingdom and Switzerland, showed that metformin had the expected effect on reducing body mass index, weight, glucose and insulin levels. Follow up studies are continuing to determine its effectiveness in preventing breast cancer recurrence.
