Secondary objectives were to describe factors such as site size associated with CPG-inconsistent care delivery and cryopreservation completion. Methods: This retrospective, multicenter study included patients 15 to 21 years old with a first cancer diagnosis from January 2014 through December 2015 who were previously enrolled to a Children's Oncology Group (COG) study and received care at a participating NCORP site. Patients were randomly selected from a list generated by the COG for chart review by participating sites. Primary outcome was care delivery that was inconsistent with a strong CPG recommendation on FP, namely discussion and offering of FP options before cancer treatment initiation, as adjudicated centrally by a panel. Results: A total of 129 patients from 25 sites were included. Among these, 48% (62/129) received CPG-inconsistent care. Most CPG-inconsistent care was due to lack of FP discussion documentation (93.5%, 58/62). Small site size, treatment at a pediatric (vs mixed adult/pediatric) site, and female sex were associated with higher odds of CPG-inconsistent care delivery. Conclusions: Newly diagnosed pediatric cancer patients often received CPG-inconsistent care for FP, with disproportionate gaps noted for females, and those treated at smaller or pediatric NCORP sites. The primary reason for CPG-inconsistent care is lack of FP discussion from clinicians. Opportunities to improve FP CPG implementation are highlighted.
