PURPOSE: African American men have a higher prostate cancer risk profile th
an that of other men in the United States. The purpose of this manuscript i
s to summarize the challenges associated with enrolling and randomizing Afr
ican American and other minority participants in the Prostate Cancer Preven
tion Trial (PCPT).
METHODS: The PCPT is a randomized trial of finasteride versus placebo for p
reventing prostate cancer in healthy men age 55 years and older; it is coor
dinated by the Southwest Oncology Group. The manuscript describes demograph
ic and lifestyle characteristics of the PCPT randomized sample (18,882 men)
by four racial and ethnic groups (Caucasian, African American, Hispanic, a
nd other). African American men comprised 4% of the total randomized sample
compared to our goal of 8%. Minority recruitment was emphasized through th
e Study Manual and training that occurred at trial activation. Supplemental
minority recruitment activities were initiated a year after study activati
on and continued through the end of the accrual period. Minority recruitmen
t was emphasized as follows: minority recruitment presentations at PCPT tra
ining seminars (held during twice yearly Southwest Oncology Group meetings)
; distribution of additional minority recruitment materials; engagement of
four consultants for minority recruitment; production of a Minority Recruit
ment Manual; and a small pilot study involving minority outreach recruiters
at five PCPT sites.
RESULTS: The consultants were helpful in implementing the pilot project and
in suggesting and reviewing materials for minority recruitment. The five-s
ite pilot project did not increase either enrollment or randomization of mi
norities (with a possible exception at one site).
CONCLUSIONS: We suggest that a long term perspective is required for succes
sful recruitment of minority participants in clinical trials. Likewise, ext
ensive minority recruitment efforts must be ready to implement at trial act
ivation. (C) 2000 Elsevier Science Inc. All rights reserved.
