Smokers and Breast Radiotherapy
Radiotherapy may not help breast cancer patients that smoke.
A landmark study reveals the impact of smoking on survival of breast cancer patients. A recently published Oxford University study has analyzed the data from numerous other peer-reviewed publications that smokers have a disproportionate risk of developing and dying from lung cancer following breast radiation therapy. This meta-analysis reveals that smokers constitute a different “class” and as such, are at a much higher risk of developing lung cancer. In the study, the data from 40,781 patients reported in those publications between 2010 and 2015 (the so-called modern era for breast radiotherapy) were randomly analyzed based on surgery and radiation versus surgery alone.
Andrea McKee, MD, Radiation Oncologist at the Lahey Clinic notes, “For early-stage breast cancer patients who meet the requirement for partial breast irradiation, I more heavily weight the PBI option to avoid exposure to the lungs, considering the odds of secondary malignancies.”
