No differences were observed between patients with and without events with respect to the endocrine phenotype (p = 0.170), laterality (p = 0.641), T stage (p = 0.571), tumor volume (p = 0.491), adrenal capsular invasion (p = 1.000), venous invasion (p = 1.000), Ki67 index > 15% (p = 0.479), 5-item score (p = 0.872), and pS-GRAS group (p = 0.218) as well as adjuvant chemotherapy (p = 1.000) and mitotane therapy (p = 1.000). Here, MKI67 is linked to neoplasm.
