Correlates of Adjuvant Therapy Attitudes in African American Breast Cancer Patients.

Purpose: Black breast cancer patients delay and underutilize adjuvant breast cancer therapies; yet, very few studies have specifically examined Black women's attitudes toward breast cancer therapy. This study observed the influence of self-reported interpersonal processes of care (e.g. self-efficacy) clinical and sociodemographic factors and sociocultural (e.g. religiosity), related to Black breast cancer patients' attitudes toward radiation and systemic therapies (chemotherapy and adjuvant endocrine therapy - "AET").

Methods: This was a secondary analysis of data from the Narrowing Gaps in Adjuvant Therapy Study (2006-2011). The analysis included 210 Black women who were newly diagnosed with breast cancer. Bivariate and multiple regression analyses were performed between independent variables (e.g., demographics) and three outcome variables (chemotherapy, AET, and radiation therapy) to asses women's perceptions of therapy type. The lasso method was used to select variables correlated with therapy attitudes.

Results: Most women reported negative attitudes toward AET (56%) and radiation (54%); fewer negative attitudes were observed toward chemotherapy (47%). Higher education and greater perceived susceptibility of a recurrence were associated with more positive attitudes toward chemotherapy. Regarding radiation therapy, women with greater patient satisfaction were more likely to have more positive attitudes.

Conclusions: Our study findings may aid in the development of behavioral interventions targeted to mitigate Black women breast cancer treatment disparities. We found modifiable factors (e.g. communication, satisfaction ratings) that support opportunities for clinicians to better address Black women's needs regarding adjuvant treatment options. The development of tailored interventions for newly diagnosed Black breast cancer patients on patient related factors in health care are warranted for Black women with lower educational levels.
