Abstract:
Background: Lack of representation in genomic databases limits the generalizability of study findings, predictive models, and therapeutics. In cancer, the development of nearly 75% of cancer drugs have been informed by genomic data,1 yet there is persistent lack of diversity of genomic testing databases that inform clinical trials and lead to drug approval.2,3 The PROFILE project at Dana-Farber Cancer Institute (DFCI) is available to all adult cancer patients, offering free genomic testing for inclusion in their genomic database. Herein, we describe the enrollment ratios in PROFILE delineated by demographic group and cancer type. Methods: We conducted a cross-sectional analysis of the prevalence of PROFILE enrollment 7/8/2011 – 1/1/2022. Over this time period 177,788. Enrollment processes vary in each DFCI disease center, but all solid tumor patients are meant to be approached for enrollment around the time of their first visit. The electronic health record was queried to identify demographics, which are collected by registration staff at intake. Queried demographics included gender, age ( & lt;70/≥70 years old), race, ethnicity, marital status, English proficiency, and primary language; cancer type was also queried. Prevalence was calculated from the number of patients enrolled each year and the total patients for that year. The association between PROFILE enrollment and demographic groups were determined with χ2 tests. Results: Across DFCI, 41% of adult patients are enrolled in PROFILE (73,730 enrolled). Enrollment was most common in the following groups (% of DFCI population, % of enrolled): female (57, 54), younger (78, 79), white (90, 93), non-Hispanic (97, 98), married (68, 70), English proficient (96, 98), hematologic malignancy (20, 18). Differences were statisticially significant for each category (p-value & lt;0.0001). Conclusion: This data suggests that, despite the universal availability of genomic testing for DFCI patients, disparities still result in underenrollment of certain groups, particularly by race and English proficiency. Ongoing projects at DFCI aim to increase enrollment with decision-making support through a patient navigator and informational video among key patient groups, including older adults, racial minorities, Latinx, and limited English proficient. 1.
