No clear standard treatment guidelines exist for older women with breast cancer. In this study we aimed to examine the practice patterns and treatment outcomes of women ≥80 years old with invasive breast cancer. A retrospective chart review at a single academic institution was performed of 124 women diagnosed with stage I to III invasive breast cancer aged ≥80 years between 2005 and 2014. Median age of diagnosis was 84 years. Fifty-nine of the cancers (48%) were detected using mammography. One hundred twelve patients (90%) underwent surgery. There was no difference in comorbidities between the surgical and nonsurgical group (P =.800). In multivariate analysis, age was predictive of receiving surgery (P <.001). Overall survival probability was higher for those who received hormonal therapy (P =.002), radiation therapy (P =.041), and those with lower-stage tumors (P =.018). Surgery was not predictive of survival. It is important to consider comorbidities, complications and, longevity when determining whether elderly women diagnosed with breast cancer benefit from surgery.
