Abstract
Purpose: To examine cancer-related follow-up (CRFU) health care utilization associated with fertility experiences among diverse adolescent and young adult (AYA) cancer survivors.
Methods: Project Milestones is an ongoing survey study evaluating life outcomes among AYAs diagnosed with cancer at age 21-39 in Los Angeles (LA) County. AYAs had an initial 5-year survival probability of ≥50% and are currently 3-10 years post-diagnosis. A registry-based recruitment strategy through the SEER-affiliated LA Cancer Surveillance Program was used.
Results: Overall, 1442 AYAs responded (Table 1). Compared to AYAs who did not, AYAs who saw: (1) their treating provider for CRFU were more likely to report a fertility discussion (56.0% vs. 41.2%, p&lt;.01); (2) another provider for CRFU were less likely to report a fertility discussion (38.1% vs. 52.0%, p&lt;.01); (3) their treating provider for CRFU were more likely to report preserving fertility (14.7% vs. 8.4%, p&lt;.01); (4) a primary care provider for CRFU were less likely to report preserving fertility (10.1% vs. 13.6% p&lt;.05). Compared with AYAs who reported a CRFU visit 1+ years ago or never, AYAs with a visit &lt;1 year ago: (1) had on average greater reproductive concerns (range 5-25, higher scores reflect greater concern, 13.8 vs. 13.4, p&lt;.05); and were more likely to report (2) worry passing on a genetic risk for cancer to their child (55.6% vs. 47.8%, p&lt;.01); and (3) caution about having children because they may not be around to raise them (23.6% vs. 16.6%, p&lt;.01).
Discussion: Iatrogenic infertility concerns persistent into survivorship, yielding a need to optimize oncofertility care throughout the reproductive lifespan. Receiving CRFU care from the treating provider is related to better outcomes, and higher reproductive concerns among AYAs with a recent visit may reflect greater awareness of risk due to more points of contact with a provider.
