Key clinical point: Chemotherapy-related amenorrhea (CRA) was common in premenopausal women with stages I-III breast cancer (BC), particularly in those who were older, experienced hot flashes, or received adjuvant tamoxifen.
Major finding: The majority (57.1%) of premenopausal patients with BC reported having persistent CRA, with the likelihood increasing in those who were age ≥ 35 years (adjusted odds ratio [aOR] 35-39 years: 1.84, 40-44 years: 5.90, ≥45 years: 21.29; all P < .001), experienced hot flashes at diagnosis (aOR 1.83; P = .01), or received adjuvant tamoxifen (aOR 1.97; P < .001) .
Study details: This study analyzed the data from the Cancer Toxicities Study and included 1636 premenopausal women with stages I-III BC who were age < 50 years and received chemotherapy but not ovarian function suppressants.
