The impact of facility volume/size on breast cancer treatment and outcome.
Recent studies have suggested that outcomes and survival from breast cancer are improved when definitive treatment is rendered at high-volume and/or teaching centers. Consolidation of such cases in tertiary centers, however, is often impractical and impossible. Patients often desire primary treatment of their breast cancer in their own communities. The current study was undertaken to examine the impact of treatment facility type on the treatment performed as well as on overall survival. Breast cancer treatment and survival data were available from the American College of Surgeons National Cancer Data Base. Only patients in whom no previous treatment had been rendered were included in the analysis. Data were stratified with regard to type and size of treatment facility/hospital; stage distribution; initial treatment performed; and 1-, 2-, and 5-year survival. A total of 665,409 patients were included in the current analysis. There were no significant differences in stage distribution between facility types nor was there a significant difference in the treatment performed (although there was a slight trend toward breast conservation at the larger centers). This was true overall and for each stage of cohort. There were also no significant differences in 1-, 2-, and 5-year survival rates overall and at any stage (although again, there was a slight trend toward a minimal survival advantage at the larger centers). There was no significant impact of facility size or type on either breast cancer treatment performed or overall survival. There was no evidence that more "advanced" treatments were offered at larger centers nor was there evidence of improved outcome/survival at larger centers. Care can be rendered safely, efficiently, and effectively in the community setting.
