OBJECTIVES:  Inflammatory breast cancer (IBC) is a rare and aggressive form of cancer with poor outcomes. This study aims to assess age differences in IBC survival among all, white, black, estrogen receptor positive (ER+) and estrogen receptor negative (ER-) patients. METHODS:  Using the Surveillance, Epidemiology, and End Results (SEER) data, IBC female patients diagnosed between 1990 and 2013 were identified. Patients were divided into five groups according to their age at diagnosis: 18-34(younger patients), 35-49, 50-64, 65-74 and 75 and above (older patients). The 36-month inflammatory breast cancer-specific survival (IBCSS) was estimated using the Kaplan-Meier method and compared across groups using the log-rank test. Stratified multivariable Cox proportional hazard ratios (HRs) were used to assess the association between age and survival among all, white, black, ER+ and ER- patients after adjusting for patient and tumor characteristics. RESULTS:  A total of 13,748 IBC patients were identified; 3.8% were diagnosed between the ages of 18-34, 25.0% between 35-49, 38.8% between 50-64, 16.9% between 65-74, and 15.5% aged 75 and above. The 36-month IBCSS Kaplan-Meier curves showed younger patients had a better crude survival compared to older patients among all (58% vs 52%), white (60% vs 52%), ER+ (76% vs 64%) and ER- (48% vs 41%) subgroups, and the same survival among the black subgroup (48% vs 48%). The adjusted HRs were higher for older versus younger patients for all, white, ER+ and ER- patients, but not for black patients. Compared to younger patients, the adjusted HRs for older patients were 1.28(95%CI:1.11-1.47), 1.32(95%CI:1.12-1.56), 1.07(95%CI:0.79-1.45), 1.28(95%CI:1.01-1.63) and 1.31(95%CI:1.06-1.61) for all, white, black, ER+ and ER- patients respectively. CONCLUSIONS:  This study suggests increased age may be associated with poorer survival among all, white, ER+ or ER- patients, but not associated with poorer survival among black patients. Further research is needed to examine other variables that may affect these findings.
