Key clinical point: The risk factors for overall breast cancer (such as parity, menopausal hormone therapy use, and alcohol consumption) did not increase the risk for triple-negative breast cancer (TNBC), which had a distinct risk factor profile.
Major finding: Parity, menopausal hormone therapy use, alcohol consumption, smoking, and higher body mass index were not significantly associated with TNBC risk (all P > .05); instead, family history (odds ratio [OR] 1.55; P < .001), longer duration of oral contraceptive use (OR 1.29; P < .001), and higher breast density (OR 2.19; P < .001) were significantly associated with an increased risk for TNBC.
Study details: This meta-analysis evaluated the association between TNBC incidence and established BC risk factors using data from 33 studies.
Disclosures: This study was supported by grants from the American Cancer Society and Royal College of Surgeons in Ireland - Medical University of Bahrain (RCSI-MUB Bahrain). The authors declared no conflicts of interest.
