The results of the study MAP.3, which have been presented recently at the Annual Meeting on Breast Cancer in San Antonio (United States), show that administering exemestano as a preventive treatment to healthy women who have risk factors to develop breast cancer significantly reduces the chances of suffering this condition.
The study, which was conducted with the participation of 4,560 women from the United States, Europe and Canada (of which 432 were Spanish), began in 2004 and had the purpose of verifying to what extent the incidence of this type of cancer decreased with the administration, to women considered high risk, of an aromatase inhibitor drug.
This therapy could prevent the appearance of around 7,000 cases of breast cancer each year in Spain
The exemestano was able to reduce by 65% the possibilities of suffering the disease. The main coordinator of the MAP.3 in Spain, Dr. José Enrique Alés, estimates that, in our country alone, the appearance of around 7,000 cases of breast cancer each year could be prevented and affirms that, in addition, the study has shown that the treatment is safe and that it can therefore be applied to many women who need it.
The researchers took into account various parameters to evaluate the impact that exemestane had on the quality of life of the participants in the study, such as their sexual activity, their menopausal symptoms, their pain, their mental health ... and they found no appreciable differences between the who took exemestane and those who were part of the placebo group.
The study lasted three years and, in the case of Spanish women (with a mean of 60 years of age), 32 women in the placebo group developed the disease, compared to 11 of those who were receiving exemestane. Experts believe that the results achieved allow us to trust that this therapy can serve to better control the disease in women with a high risk of recurrence, and prevent its occurrence in those with a genetic predisposition towards this type of tumors.
