CHICAGO -- Vitamin D appeared to play little or no role in breast cancer outcomes, researchers said here. In a substudy of a large randomized trial, levels of 25-hydroxyvitamin D (25(OH)D) were not associated with overall survival (OS), relapse-free survival, or breast cancer-specific mortality, according to Ana Elisa Lohmann, MD, of Mount Sinai Hospital in Toronto, and colleagues.
The findings don't support the notion of vitamin D supplements as a way to improve outcomes, Lohmann said at the American Society of Clinical Oncology annual meeting.
