PS2-12: Age, Comorbidity and Breast Cancer Severity - Their Impact on Receipt of Guideline Therapy and Rate of Recurrence Among Older Women with Early Stage Breast Cancer

Background/Aims Mastectomy and breast conserving surgery followed by radiotherapy are considered initial guideline therapies for early stage breast cancer with randomized trials demonstrating reduced risk of recurrence. However, older women and those with comorbidities frequently receive only breast conserving surgery. The interaction of age and comorbidity with breast cancer severity and their impact on receipt of guideline therapy have not been well studied.
