Abstract
OBJECTIVE
To analyze the expression of leucine-rich and immunoglobulin-like domain gene1 (LRIG1) in pituitary tumor and its clinical significance.
PATIENTS AND METHODS
Patients were divided into two groups: hypophysoma group (n = 80) and normal group (normal brain tissue, n = 30). The immune tissue chemical streptavidin avidin-peroxidase was applied to detect the expression of LRIG1 of both groups and to analyze its relationship with the patients' prognosis.
RESULTS
The positive expression rate of LRIG1 in normal brain tissues was significantly higher than that in pituitary adenomas (100% vs. 53.8%) (p < 0.05). The positive expression rate of LRIG1 in pituitary tumors was not significantly related to age and gender, the difference was not statistically significant (p > 0.05). The positive expression rate of LRIGl in non-invasive pituitary adenomas was higher than that in invasive pituitary tumors (68.4% vs. 21.7%), the difference was statistically significant (p < 0.05). Cox multivariate survival analysis showed that LRIG1 can be used as an independent factor for prognosis evaluation. Meier survival analysis showed that the LRIG1 and pituitary tumor types were significantly associated with the prognosis of patients (p < 0.05).
CONCLUSIONS
LRIG1 was involved in the occurrence and development of pituitary tumor, the expression of LRIG1 can be used as an indicator for prognosis evaluation, and low expression indicated a poor prognosis.
