Key clinical point: The risk for breast cancer (BC) was significantly elevated in female 5-year survivors of Hodgkin lymphoma (HL) who were treated with doxorubicin between the ages of 15 and 50 years .
Major finding: The risk for BC was 1.4 times higher (95% CI 1.04-1.9) in survivors of HL who did vs did not receive doxorubicin, with the risk increasing further in survivors who received a cumulative doxorubicin dose > 200 mg/m 2 (adjusted hazard ratio 1.5; 95% CI 1.08-2.1). In fact, every 100 mg/m 2 increase in doxorubicin dose increased the risk for BC by 1.18 times (95% CI 1.05-1.32).
Study details: Findings are from a cohort study including 5-year survivors of HL (n = 1964) who received treatment between the ages of 15 and 50 years, of whom 1113 patients received doxorubicin .
