Breast cancer treatment in the elderly: Do treatment plans that do not conform to NCCN recommendations lead to worse outcomes?

Background: Aging remains one of the greatest risk factors for development of new breast cancer with more than 30% of breast cancers occurring after the age of 75. Elderly women have been found to not conform with all aspects of treatment recommendations. Our study compared outcomes of elderly breast cancer patients whose treatment did or did not conform to NCCN guidelines.
