CHICAGO — At the ASCO Annual Meeting, Lindsay Peterson, MD, breast medical oncologist at the Washington University School of Medicine, spoke with HemOnc Today about the “important” findings of the Women’s Health Initiative Dietary Modification trial.
The study found that over nearly 20 years of follow-up, postmenopausal women who decreased their fat intake and increased their fruit and vegetable intake had a 15% lower risk for all-cause mortality after a diagnosis of breast cancer and a 21% reduced risk for dying from breast cancer compared with the control arm, according to Peterson. She noted that while weight loss was not an intended outcome, a 3% reduction in weight was observed.
“These findings do need to be taken in context,” Peterson said, noting that it is not known which change in diet was responsible for the outcomes.
“The important thing is that we are seeing more and more that diet and lifestyle matter,” she said. “It is yet to be seen whether healthy diet quality alone in the absence of weight loss can impact these risk factors, but it is certainly something we will be looking at in the future.” – by Alaina Tedesco
