BACKGROUND: The purpose of this study was to examine local definitive therapy for nonmetastatic @entity0 with the Patterns of Care Breast and @entity263 (POCBP) study of the National Program of @entity5 Registries (Centers for Disease Control and Prevention). METHODS: POCBP medical record data were re-abstracted in 7 state/regional registry systems (Georgia, North Carolina, Kentucky, Louisiana, Wisconsin, Minnesota, and California) to verify data quality and assess treatment patterns in the population. National @entity5 Network clinical practice treatment guidelines were aligned with American Joint Committee on @entity5 staging at diagnosis to appraise care. RESULTS: Six thousand five hundred five of 9142 @entity1 with registry-confirmed @entity0 were coded as having @entity5 and were included in the study. Approximately 88% received guideline-concordant locoregional treatment. However, this outcome varied by age group: 92% of @entity1 < age 50 versus 80% of @entity1 >=  age 70 years old received guideline care (P   <   0.01). Characteristics that best discriminated receipt (no/yes) of guideline-concordant care in receiver operating curve analyses were the receipt of breast-conserving surgery (BCS) versus mastectomy (C   =   0.70), @entity1 age (C   =   0.62), a greater @entity5 stage (C   =   0.60), public insurance (C   =   0.58), and the presence of at least mild comorbidity (C   =   0.55). @entity1161 ( @entity1161 ) after BCS was the most omitted treatment component causing nonconcordance in the study population. In multivariate regression, the effects of the treatment facility, @entity513 in situ, race, and comorbidity on nonconcordant care differed by age group. CONCLUSIONS: Patterns of underuse of standard therapies for @entity0 vary by age group and BCS use, with which there is a risk of omission of @entity1161 . @entity5 2015;121:790-799.    2014 American @entity5 Society.
