The objective of the study was to determine the rates and predictors of fertility preservation services among reproductive-aged women with common cancers in the United States. We used the MarketScan database to identify women 18-45 years of age with lung, breast, colorectal, or cervical cancer who underwent surgery and chemotherapy from 2009 through 2016. Services from 3 months before to 3 months after chemotherapy for evaluation for fertility preservation, laboratory testing for fertility evaluation, and fertility-preserving procedures were captured. Multivariable models were used to assess the factors associated with the use of fertility-preservation services. A total of 18,781 women, including 386 cervical, 1372 colorectal, 246 lung, and 16,777 with breast cancer, were identified. In women 18-35 years old, 11.7% underwent evaluation for fertility preservation, 13.7% underwent laboratory testing, and 6.3% pursued fertility-preserving procedures. The rates of office evaluation, laboratory testing, and performance of procedure were 3.3%, 7.5%, and 1.9 % in women aged 36-40 years and 0.5%, 7.2%, and 0.3% in those aged 41-45 years, respectively. The rate of fertility preservation evaluation rose from 1.0% in 2009 to 5.5% in 2016 (risk ratio, 4.66, 95% confidence interval, 2.38-9.11) while use of fertility-preserving procedures increased from 1.0% to 4.6% (risk ratio, 3.84, 95% confidence interval, 1.94-7.59) during the same time period. In a multivariable model, use of any fertility-preserving interventions were more common in patients with breast cancer (adjusted risk ratio, 2.30, 95% confidence interval, 1.30-4.06), those in the Northeast (adjusted risk ratio, 1.24, 95% confidence interval, 1.10-1.40), and in younger women (18-35 years) (adjusted risk ratio, 2.59, 95% confidence interval, 2.32-2.89). Although limited by lack of information regarding cancer stage and desire for future fertility, only a small fraction of reproductive-aged female cancer patients receiving chemotherapy are evaluated in a nationwide sample for fertility preservation or undergo fertility-preserving procedures.
