Navigator utilization rates in breast cancer patients by race in a comprehensive cancer center.

Abstract

e18501 Background: African-Americans have the highest overall cancer death rate and shortest survival time of any racial or ethnic group in the United States. Elucidation of disparities in cancer care access is important since previous work has indicated that when equal access to Radiation Therapy (RT) in prospective randomized trials is granted, race does not independently affect outcomes. The most common cancer studied in African-American radiation therapy (RT) access disparities research is breast cancer. Furthermore, prospective analyses have demonstrated that African-Americans receive hypofractionation following breast-conserving surgery less frequently than Caucasians. As such, the goal of this study is to eventually evaluate the impact of patient navigation on short-course RT access for African-American breast cancer patients. Methods: Our study is a prospective survey-based evaluation of the impact of patient navigation on access to hypo-fractionated RT and financial toxicity in African-American breast cancer patients. As the first step to investigating the impact of patient navigation on RT access in this population, medical records of women with breast cancer in our center (University Hospitals Cleveland Medical Center, Seidman Cancer Center) were identified from support groups. The baseline navigation rate for this population was determined from the initial data collected during tumor board sessions from June 2022 through October 2022. Results: We identified female patients who were diagnosed with breast cancer and thus were eligible for navigation. From June 1st through October 31st, 30 female patients were identified. Nine (30%) were Caucasian and 21 (70%) were African-American. Of the 21 African-American female patients, only four (19%) were connected with patient navigation services. Of the 9 Caucasian female patients, only four (44.4%) were connected with patient navigation services; this difference between African-American and Caucasian patients did not reach statistical significance. The total baseline navigation rate at our center during this period was 26.67% (8 out of 30 patients). Conclusions: Over a recent five-month period, it was determined that the baseline navigation rate for Caucasian female breast cancer patients is numerically more than 2x that of African-American female patients at our comprehensive cancer center. This information is an important precursor to the first investigation of the impact of patient navigation on reducing RT access disparities facing African-American breast cancer patients. We anticipate that after collating and analyzing survey results for patients pre-RT versus post-RT as well as for those with versus without patient navigation, navigation will serve to overcome barriers in compliance to therapy and increase adherence to optimal care.
