Objective:
The aim of this study was to explore the expression of Livin in benign and malignant parotid gland tumors. We also investigate the role of Livin in the occurrence and progression of parotid gland tumors.
Patients And Methods:
Livin expression in 30 cases of normal parotid gland tissues, 40 cases of benign parotid gland tumors and 60 cases of malignant parotid gland tumors was detected by immunohistochemistry. The correlation between Livin expression and pathological characteristics of patients with parotid gland tumors was analyzed. The differentially expressed Livin in normal parotid gland tissues and malignant parotid gland tumors was determined by Western blot and quantitative Real Time-Polymerase Chain Reaction (qRT-PCR), respectively.
Results:
Livin expression was unable to be detected in normal parotid gland tissues. The positive rate of Livin expression in benign and malignant parotid gland tumors was 17.50% and 71.67%, respectively (p<0.05). Livin expression was correlated to malignant level, clinical stage and tumor diameter in 60 cases of malignant parotid gland tumors (p<0.05). However, the positive rate of Livin expression was not correlated to lymph node metastasis, age and sex of patients with parotid gland tumors (p>0.05).
Conclusions:
Livin expression is closely related to the pathological progression of parotid gland tumors, which may serve as a hallmark in diagnosis, treatment and prognosis of patients with parotid gland tumors.

Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
