Challenges in recruiting Mexican women for cancer genetics research

Abstract

Hispanic women often have low participation rates in cancer genetics research. Additionally, Hispanic sub-ethnicities may have varying accrual rates based on unique cultural factors. Hispanic women were recruited through flyers placed in the Tampa Bay Community to participate in an interview about knowledge of hereditary breast and ovarian cancer. The study goal was to recruit 20 women from each Hispanic sub-ethnicity: Puerto Rican, Mexican, and Cuban. This article reports on the difficulty in recruiting Mexican women. One hundred forty-three women called the study hotline to inquire about participation. Seventy-six callers were ineligible for the study. Thirty-four percent (n = 26) of ineligibles were Mexican women; within this group, 62% (n = 16) were unable to participate because they did not know the cancer site of their first degree relative. Inclusion criteria requiring knowledge of family history of cancer for behavioral research may be too stringent. The socio-cultural norms of Mexican families may not include discussions of cancer specifics. This study demonstrates Mexican women may have limited knowledge about their family history of cancer. Considerations of these knowledge limitations should be built into cancer genetics-related research. Referral criteria to assess the risk of hereditary breast and ovarian cancer by cancer genetics professionals are predicated on the patient providing details about cancer within multiple generations of family members, thus, posing a barrier for Mexican women who may have limited knowledge of their family history of cancer.

Genomic Disparities in Breast Cancer among Latinas

“…10 Although the overall prevalence of breast cancer in Latinas is lower than in non-Hispanic whites, Latinas tend to be diagnosed at a later stage and have worse prognostic features (eg, triple negative disease and HER2–positive disease). 3 A myriad of socioeconomic and cultural factors contribute to health disparities in breast cancer among Latinas, 4–6 but biological factors — particularly genomics — remain an important but understudied consideration.…”

A Report of the Women's Health Congress Workshop on The Health of Women of Color: A Critical Intersection at the Corner of Sex/Gender and Race/Ethnicity

“…For example, genetic testing among racial/ethnic minorities is underutilized. 15 , 16 Patients are often confused about the difference between germ line and somatic testing, and some individuals are concerned about the harms of germ line screening. African Americans are more concerned about the harms of genetic testing than white Americans, but are just as likely to participate in predictive, prognostic, and pharmacogenomic testing.…”

Risk terminology in biobanking and genetic research: What's in a name?

“…[Quinn et al, 2011]) reported on an experience in recruiting a diverse group of Hispanic women for a behavioral study on knowledge of hereditary breast and ovarian cancer syndrome. The goal of the research was to identify women of Cuban, Puerto Rican, and Mexican origin with a first degree relative who had had breast cancer before age 50 or ovarian cancer at any age.…”
