Efavirenz-estrogen interactions are documented; however, the survival impact is unknown. Survival between women with estrogen-receptor positive breast cancer taking efavirenz (nā€Š=ā€Š38) and nonefavirenz regimens (nā€Š=ā€Š51) were compared. The 5-year overall-survival was 48.9% [95% confidence interval (CI) 33.0-72.2 and 51.1% (95% CI 34.0-76.8)] in the efavirenz and nonefavirenz groups, respectively suggesting efavirenz is unlikely driving poorer survival in women living with HIV and estrogen-receptor positive breast cancer.
