A significant correlation between SUVmaxT and grade (r = 0.356, p = 0.001), Ki-67 (r = 0.434, p < 0.001), lymph node status (r = 0.333, p = 0.015), tumor histology (r = − 0.279, p = 0.012), and tumor subtype (r = 0.237, p = 0.034) was noted (Fig. 4). The gene discussed is MKI67; the disease is neoplasm.
