Minority Accrual On A Prospective Study Targeting A Diverse Us Breast Cancer Population: An Analysis Of Wake Forest Ccop Research Base Protocol 97609

6564 Background: Clinical trial accrual rates are lower among minority patients. Wake Forest CCOP RB protocol 97609 designed to accrue 400 non-Hispanic White (NHW) and 600 minority patients to a study evaluating potential genomic single nucleotide polymorphisms as markers for breast radiosensitivty. Methods: Accrual data evaluated from 24 participating CCOPs and numerous CTSU sites. Race / ethnicity self-reported by participants (NHW, non-Hispanic Black, Hispanic/Latino, Asian /Pacific Islander, or American Indian/Alaskan Native) based on ACS reporting criteria. Results: 752 participants accrued in 14.5 mths (11/11-1/13); 402 NHW and 350 minorities. NHW accrual goal reached, 5.9 months (period 1; avg 68.4 participants /month) compared with 54 minority participants (period 1; avg 9.2 participants / month). This 7.4 ratio NHW to minority accrual is higher than expected given incidence. During 8.6 months following closure NHW enrollment (period 2), 296 minority participants accrued (avg 34.3 participants/mon...
