Prospective cohort study of association of diet quality with survival of Black women with epithelial ovarian cancer

Ovarian cancer survival among Black women is the lowest across all racial and ethnic groups. Poor dietary quality als disproportionally affects Black populations. Analysis of patients in the cohort of the prospective African American Center Epidemiologic Study investigated the association of diet quality in the year before diagnosis with survival among Black women with epithelial ovarian cancer (EOC). In this cohort study of 483 patients, there was no signifcant difference in overall mortality according to diet quality. However, in the subgroup of patients with high-grade serous ovarian cancer (HGSOC; n=325), higher diet quality in the year before diagnosis was associated with higher survival rates. The authors conclude that for Black women with the lowest prediagnosis adherence to dietary guidelines, modest improvements in dietary quality may be associated with improved survival for the most lethal EOC histotype.
