Breast cancer patients who are overweight or obese might benefit less from treatment with docetaxel, a common chemotherapy drug, than lean patients. An international team of researchers based this conclusion on a retrospective analysis of data from a large clinical trial. In most European countries, more than 50% of women are overweight or obese. In the United States this is the case for over 63% of women and this proportion is expected to further increase in the coming years. It is not widely known, but obese women have a higher risk of getting breast cancer and obese breast cancer patients have a higher risk of relapsing. Moreover, while many cancer patients are overweight or obese, the efficacy of anticancer drugs according to their BMI is generally not known.
