Key Points Question How are adjuvant endocrine therapy initiation timelines associated with adherence and continuation of treatment in low-income women with breast cancer? Findings In this cohort study of 1711 women with breast cancer enrolled in Medicaid, longer time to initiation of adjuvant endocrine therapy was associated with lower odds of short-term and long-term adherence as well as short-term continuation. Meaning These results suggest that interventions that focus on improving timeliness of treatment initiation may also improve adherence to treatment and therefore further improve outcomes, bringing benefits of advances to all women with breast cancer.
