Latina breast cancer patients given information about clinical trials in multiple ways, including a culturally sensitive video on breast cancer clinical trials, had much greater awareness of trials than patients who got usual-care information, according to new data.
After receiving the extra information—an interactive video about clinical trials, a bilingual booklet, and access to a patient navigator who can help answer their questions—the proportion of Latina breast cancer patients taking steps toward participating in a clinical trial increased from 38% to 75%, according to the study. The study was led by researchers from the Institute for Health Promotion Research (IHPR) at The University of Texas Health Science Center at San Antonio (the team behind SaludToday) and presented at an American Association for Cancer Research (AACR) conference Nov. 9-12, 2014 in San Antonio.
Researchers says this is a potential way to increase Latino representation in clinical trials.
“Latinos represent 17% of the U.S. population but only 5.6% of participants in National Cancer Institute treatment clinical trials,” said Dr. Patricia Chalela, an IHPR researcher who is part of the study team led by IHPR Director Dr. Amelie G. Ramirez. “Underrepresentation of minorities in clinical trials results in disparities of cancer outcomes and limits generalizability of the findings because researchers cannot study how minority patients respond to new treatments.”
The study is in its last year of recruitment, with 71 of 112 enrolled so far.
Participants are randomly assigned to usual-care clinical trial information or the additional information.
Compared with patients assigned to usual-care information, patients assigned to additional information had significantly higher awareness of clinical trials, in particular, the purpose of clinical trials, the requirements for enrollment, the benefits and risks of clinical trials, and the potential of clinical trials as an appropriate treatment for a serious disease.
“We hope that computer-based videos specifically tailored for Latinos will provide an effective strategy to increase Latina breast cancer patients’ knowledge, understanding, and participation in clinical trials, although this needs confirming in larger studies,” Chalela said.
This study was supported by funds from Susan G. Komen for the Cure, the the Cancer Therapy and Research Center (CTRC), and Redes En Acción, a National Cancer Institute–funded Latino cancer research network based at the Institute for Health Promotion Research at the UT Health Science Center San Antonio.
