Impact of age on genomic alterations and the tumor immune microenvironment in papillary thyroid cancer.

ABSTRACT: Differentiated thyroid cancer in older adults has been linked to alterations in the mutational landscape and tumor immune cell infiltration that create a tumor-permissive microenvironment. We sought to determine the impact of age on genomic alterations and immune cell composition in papillary thyroid cancer (PTC). Genomic alterations, immune cell composition, and clinical data were obtained using The Cancer Genome Atlas and computational immunogenomic analyses. Disease severity was recoded into three groups: Group A (T1-2N0M0), Group B (T1-3N1a-1bM0), and Group C (T4NxMx or TxNxM1). Histopathologic subtypes included conventional, follicular-variant, and tall cell variant PTC. Spearman's rank correlation, ANOVA, t-test, and multivariable linear regression were performed. A total of 470 PTC
