ITGAL and thyroid cancer, nonmedullary, 2: ITGAL mRNA expression (n = 161 cases, of which 81 were benign and 80 were malignant) did not differ between malignant (1.04 ± 1.63 AU) and benign thyroid nodules (0.76 ± 1.21 AU, p = 0.2131) or among the histological types evaluated (PTC vs goiter, p = 0.1652; PTC vs FA, p = 0.7297; PTC vs FTC, p = 0.6662; FTC vs goiter, p = 0.2335; FTC vs FA, p = 0.4256 and FA vs goiter, p = 0.3029).
