Abstract

Purpose: Fertility is a concern for young women with breast cancer. We explore patient preferences for chemotherapy and whether women will trade-off survival benefits to maintain fertility following standardized information delivery. Methods: During a standardized interview, outcomes associated with adjuvant chemotherapy and 5 years of tamoxifen (CT) or 5 years of tamoxifen alone (NoCT) were described to participants. A threshold task was performed, in which each participant participated in two scenarios: (1) 10% absolute survival benefit from treatment and (2) 25% absolute survival benefit from treatment. The threshold point represented the reduction in fertility post-treatment that a participant would accept before she would trade-off CT benefit. Descriptive statistics were used to characterize participants. Demographic factors (age, marital status, parity at diagnosis, and education) associated with willingness to trade-off survival benefits were evaluated with logistic regression. Results: Analysis comprised 50 women with a median age of 34.5 years (range 25-39 years). Thirty-nine women (78%) completed university education. Thirty-four (68%) and 45 (90%) women in scenarios 1 and 2, respectively, were willing to trade-off all fertility (i.e., reduce fertility to 0% chance of conceiving naturally) to undertake CT and maintain survival benefits. Eight (16%) and three (6%) women in scenarios 1 and 2, respectively, chose to not pursue CT at all to maintain natural fertility. Regression analysis did not identify any variables that were predictive of participants' preferences. Conclusion: Most women with breast cancer are not willing to trade-off survival benefits of adjuvant therapy to maintain fertility.
