Description
BACKGROUND: Significant improvements in the survival of women with breast cancer have been observed and are attributed to a multidisciplinary approach and the introduction of polychemotherapy and endocrine regimens. The objective of this population-based study was to determine whether women with inflammatory breast cancer (IBC) who received treatment in a modern era had a poorer survival compared those with non-IBC locally advanced breast cancer (LABC). METHODS: The Surveillance, Epidemiology, and End Results program registry was searched to identify women with stage IIIB/C breast cancer diagnosed between 2004 and 2007 who had undergone surgery and radiotherapy. Patients were categorized as either having IBC or non-IBC LABC according the sixth edition of the American Joint Committee on Cancer (AJCC) criteria. Breast cancer-specific survival (BCS) was estimated using the Kaplan-Meier product limit method and compared across groups using the log-rank statistic. Cox models were then fitted to compare the association between breast cancer type and BCS after adjusting for patient and tumor characteristics. RESULTS: A total of 828 (19.2%) women and 3476 (80.8%) women had stage IIIB/C IBC and non-IBC LABC, respectively. The median follow-up was 19 months. The 2-year BCS rate was 90% (95% confidence interval [95% CI], 88%-91%) for the entire cohort and 84% (95%CI, 80%-87%) and 91% (95%CI, 90%-91%) among women with IBC and non-IBC LABC, respectively. In the multivariable model, patients with IBC were found to have a 43% increased risk of death from breast cancer compared with patients with non-IBC LABC (hazard ratio, 1.43; 95%CI, 1.10-1.86 [P =.008]). CONCLUSIONS: In the era of multidisciplinary management and anthracycline-based and taxane-based polychemotherapy regimens, women with IBC continue to have worse survival outcomes compared with those with non-IBC LABC.
