Unlabelled INTRODUCTION: Cancer causes significant morbidity and mortality in the United States. It is the second most common cause of death in the United States, after heart disease. African Americans are disproportionately affected by malignancy, with overall higher death rates compared to other racial and ethnic groups. Screening tests can identify early stage malignancy allowing for timely intervention. However, African Americans less frequently undergo cancer screening. Advancement in genomic technology has led to the identification of signals for cancer in the blood. This has resulted in the development of multi-cancer early detection (MCED) tests which evaluate for circulating cell-free DNA (cfDNA). This study evaluated physicians' perception of the use of a multi-cancer early detection test (MCED).MethodsAn anonymous, 29 question survey was administered to African American / Black physicians and medical students. Survey participants were identified through the National Medical Association and other professional organizations that included primarily African American physicians. Surveys were excluded from analysis if respondent was non-African American / Black or was not a physician or medical student. The survey collected physician demographics, percentage of African American / Black patients in their practice, patient barriers to screening, potential use of MCED tests and factors influencing decision to recommend testing. Descriptive statistics were generated. Additional analysis was performed using Chi-Square with statistical significance set at p-value <0.05. The survey was pilot tested for reliability and validity.Results1196 (681 female, 515 male) physicians and medical students completed the survey. 95.8 % were physicians who were or had been in clinical practice. Fifty-three percent of physicians reported that >40 % of their patients were African American / Black. Barriers to cancer screening included lack of understanding of the importance (33.8 %), lack of or limited insurance coverage (23.5 %), socioeconomic factors unrelated to insurance coverage (16.2 %), fear of cancer (8.8 %), history of racism and bias in the health care system (7.4 %) with 8.8 % reporting 'other' and 1.5 % reporting no perceived barriers. There was a significant difference (p<0.03) in the rate that physicians' perceived racism and bias in the health care system as barrier for cancer screening in African American / Black patients when compared to other patients. Most physicians and medical students indicated that a MCED test would benefit all patients (86.8 %), would encourage further cancer screening tests (83.8 %), and would be beneficial for minority and under-represented patients regardless of socioeconomics or health care access (83.8 %). Seventy-five percent of survey respondents indicated that a MCED test would be beneficial in promoting further cancer screening and early detection in African American / Black patients. Factors that would impact the ordering of an MCED test included scientific evidence and test validity (63.2 %), efficiency, accessibility, ease of ordering and ease of receiving results (11.8 %), insurance coverage (13.2 %) and 'other factors' (11.8 %).DiscussionThis is one of the largest surveys to assess physicians' perceptions about MCED testing and is the first study to evaluate the perspectives of African American physicians. It offers insight about physician acceptance and potential incorporation of MCED into clinical practice. It is important that a multifaceted approach is employed to improve cancer outcomes and reduce disparities in survival. MCED tests, a relatively new advancement in genomic technology, have the potential to be an important component in cancer screening strategies.Copyright © 2024 National Medical Association.
