• W2891619627 abstract "e18267 Background: ASTRO ‘Choosing Wisely recommendations’ (CWr) note radiation therapy (RT) interventions lacking evidence of benefit in cancer care. This study evaluates adherence to the 2013 CWr to ‘not routinely use intensity modulated radiotherapy (IMRT) to deliver whole breast radiotherapy as part of breast conservation therapy’ using a novel linkage between the Western WA Cancer Surveillance System (CSS) and claims from two large commercial insurance plans. No studies have evaluated adherence to this CWr in a commercial insurance setting. Methods: CSS records for first primary Stage I/II breast cancer cases (2008-2015) were linked with Premera Blue Cross and Regence Blue Shield claims. Included cases had coverage for ≥12-months before/after diagnosis (or until death), lumpectomy within 6 months of diagnosis, and RT within 6 months of lumpectomy. We used generalized estimating equations (GEE) to evaluate associations between demographic (age, race) and tumor (grade, laterality, diagnosis year) variables and use of IMRT vs conventional conformal RT within 1 year of diagnosis. Results: We identified 1,048 first primary Stage I/II breast cancer cases that met inclusion criteria. Mean age was 61, 91% were white, 52% were left-side cases. The non-adherent proportions are in the table below. In GEE analysis, only left-side cases (OR=6.4, p<0.001) and years of age (OR=1.03, p<0.01) were independently associated with IMRT use. Conclusions: Patients with IMRT vs. conventional conformal RT after lumpectomy may incur additional cost without commensurate clinical benefit. In the first study of adherence to a CWr against IMRT in this setting, we found that left-side cases were 6-fold more likely to be non-adherent vs right-side cases. This association suggests that IMRT is being used to reduce radiation dose to the heart, though not supported by evidence. Overall, the small non-adherent proportion before/after the CWr suggests alignment between guidelines and use of IMRT in Western WA. Future studies should evaluate IMRT use in other regions and develop strategies to improve CWr adherence in left-side cases. [Table: see text]" @default.
