Evaluation of plasma insulin-like growth factor binding protein-2 as a marker for adrenocortical tumors

Abstract

These results indicate that plasma IGFBP-2 is elevated in patients with malignant adrenocortical tumors and that the major factor affecting IGFBP-2 levels in these patients is tumor stage. However, plasma IGFBP-2 was less sensitive than expected for a tumor marker, which may limit its value in the diagnosis and follow-up of adrenocortical carcinoma.
