• W2890156879 abstract "52 Background: Breast cancer (BC) is the most common malignancy in women with estimated care costs of $20.50 billion/year by 2020. In 2012, ASCO released the Choosing Wisely Initiative which recommended against the use of routine imaging in patients with newly diagnosed early stage BC. We examined the adherence rate and factors associated with non-adherence in patients with early stage BC treated within a large health care system. Methods: We identified all women with stage I-II BC diagnosed between January 1, 2014 and December 31, 2015 from the Cancer Registry of Mount Sinai Health System. Demographic, clinical and treatment related factors were collected. Medical records were reviewed to identify patients who had routine staging scan. Data of initial and follow-up imaging over 1-year period were collected. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated from logistic regression models. Results: Among 733 BC patients, the median age at diagnosis was 58 (range 26-98). One hundred thirty nine patients (19%) had routine imaging with a mean number of initial scans of 1.53 and 59 (42%) patients had at least 1 subsequent scan in the 1-year follow up (range 1-4 scans/year). PET/CT was the most frequent modality, followed by CT. Medical oncologist was the ordering provider in 52% of the cases and surgical oncologist in 44.6%. Routine scan identified no cases of metastatic disease. False-positive findings were identified in 43% and incidental findings in 8% of cases. Total cost of imaging in this group was $4480/patient. Young age ( < 50), TN disease, tumor size > 2cm and positive lymph node were associated with increased staging scan on univariate and multivariate analysis. Conclusions: Our study highlights the prevalence of unnecessary scan in up to 19% of patients with stage I-II BC. Routine imaging resulted in increased radiation exposure and additional cost of $4480/patient. The presence of T2 tumor, positive lymph node, TN disease and young age were associated with increased staging scan. Further educational efforts are needed to avoid unnecessary scans in patients with early stage BC. [Table: see text]" @default.
