Purpose: We sought to enumerate secondary medical conditions from hospitalization records in adolescent and young adult (AYA) differentiated thyroid cancer (DTC) survivors and identify characteristics of patients with increased likelihood of subsequent medical diagnoses. Methods: Using data from the California Cancer Registry and statewide hospitalization data, we examined incident oncologic, endocrine, pulmonary, hematologic, and cardiovascular diagnoses in 12,312 AYA (aged 15-39) patients diagnosed with DTC in 1996-2012 and surviving >2 years after diagnosis with follow-up through 2014. We calculated the cumulative incidence of each condition accounting for the competing risk of death and used multivariable Cox proportional hazards regression to evaluate sociodemographic and clinical characteristics associated with each incident condition. Results: The 10-year cumulative incidences of multiple medical conditions were particularly high in blacks and Hispanics. Asian/Pacific Islander survivors were most likely to develop subsequent cancers. Men had higher rates of cardiovascular and diabetes diagnoses than women, but lower rates of asthma and cytopenias. Low socioeconomic status and/or public or no insurance were associated with a higher risk of several diagnoses. More extensive disease stage and thyroid surgery increased the risk of calcium and phosphorus metabolism disorders. Neck reoperation associated with the risk of cytopenias, as well as subsequent endocrine, cardiovascular, and respiratory diagnoses. Conclusion: The incidence of medical conditions after thyroid cancer diagnosis and treatment differ among racial/ethnic groups and sexes. Those residing in lower socioeconomic neighborhoods, those with public or no insurance, and those who require further neck surgery have substantially higher burdens of subsequent medical diagnoses.
