BackgroundAfrican-American women have a lower survival rate than white women following a diagnosis of invasive breast cancer. Limited information is available regarding the impact of race on results of breast conservation therapy (BCT).MethodsLocal recurrence rates were compared in 71 African-American patients (73 breasts) and 204 white patients (208 breasts) with stage I and II breast cancer treated with BCT.ResultsOverall 5-year actuarial recurrence rates were 13% in African-Americans and 4% in whites (P = 0.075). These rates were 9% and 4%, respectively, if patients with local skin/soft tissue recurrences were excluded (P = 0.587). Exclusion of these skin/soft tissue failures eliminated any significant difference seen in recurrence between stage II African-American and white patients (P = 0.163). African-American women had less favorable recurrences, including tumor in more than one quadrant or local skin/ soft tissue involvement (P = 0.001).ConclusionsOverall actuarial recurrence rates were slightly higher, but not significantly different, in African-American and white women following BCT. A much less favorable pattern of local recurrence was seen in the African-American patients (P = 0.001), which may represent the presence of more biologically aggressive tumors in these women.
