Elevated CCAT2 expression predicts poor prognosis of patients with pituitary adenomas. A. The CCAT2 expression levels in pituitary adenomas tissues and corresponding normal tissues from 74 patients were examined by RT-PCR. B. Kaplan-Meier survival curve and log-rank test were used to evaluate the association of CCAT2 expression with overall survival rate. Patients were segregated into CCAT2-high group and CCAT2-low according to the median of CCAT2 expression in pituitary adenomas tissues.
