Key clinical point: Women who were diagnosed with breast cancer (BC) at a young age and underwent fertility preservation (FP) did not experience any increased risk for disease-specific mortality or relapse.
Major finding: Compared with women who did not undergo FP, disease-specific mortality was similar in women who underwent hormonal FP (adjusted hazard ratio [aHR] 0.59; 95% CI 0.32-1.09) and nonhormonal FP (aHR 0.51; 95% CI 0.20-1.29). Hormonal (aHR 0.81; 95% CI 0.49-1.37) and nonhormonal (aHR 0.75; 95% CI 0.35-1.62) FP were associated with similar relapse or death rates in a subcohort of 723 women with complete relapse information.
Study details: Findings are from an analysis of a population-based nationwide cohort study including 1275 women of reproductive age (18-44 years old) who were diagnosed with BC, of which 425 women received hormonal (n = 367) or nonhormonal (n = 58) FP treatment.
