Objective: To examine whether female cancer survivors are more likely to pursue care for infertility after cancer than women without cancer., Design: Population-based cohort study involving detailed interviews regarding reproductive history., Setting: Not applicable., Patients: Female cancer survivors aged 22-45 years, who were at least 2 years after a cancer diagnosis between the ages of 20 and 35 years (n = 1,036), and age-matched comparison women with no cancer history (n = 1,026)., Exposure: History of cancer vs. no history of cancer., Main Outcome Measure(s): Each cancer survivor was randomly matched to a comparison woman, who was assigned an artificial age at cancer diagnosis equal to that of her match. Matching was repeated 1,000 times. Outcomes of visiting a doctor for help becoming pregnant or undergoing fertility treatment were modeled using Cox proportional hazards regression, comparing survivors after a cancer diagnosis to age-matched comparison women, adjusted for race, income, residence, education, and parity., Results: Only 25.5% of cancer survivors reported meeting their desired family size before a cancer diagnosis. The median time from diagnosis to interview among survivors was 7 (interquartile range 5-11) years. Cancer survivors were more likely to report having no children (32.6%) at the interview compared with women with no cancer history (19.5%). Survivors were not more likely to visit a doctor for help becoming pregnant compared with women without a cancer history, matched on birth year and followed by the age at which cancer survivors received their diagnosis (hazard ratio [HR] 1.16, 95% simulation interval [SI] 0.78-1.74). Compared with cancer-free women, cancer survivors had similar probabilities of pursuing any treatment (adjusted HR [aHR] 0.88, 95% SI 0.46-1.56), using hormones or medications (aHR 0.86, 95% SI 0.46-1.63), or undergoing intrauterine insemination (aHR 1.26, 95% SI 0.40-5.88) to conceive. Cancer survivors were slightly more likely to pursue surgical interventions to become pregnant (HR 1.55, 95% SI 0.67-3.71). Of those who visited a doctor but declined to pursue fertility treatment, one-quarter of women reported declining treatment due to cost., Conclusion: Cancer survivors did not use fertility treatments at higher rates than the general population. Further counseling and education surrounding fertility options are recommended for young adult female cancer patients after treatment is completed., Competing Interests: Declaration of Interests L.M.K. has nothing to disclose.
