To investigate the expression of rapamycin target protein (mTOR) mRNA and transferrin receptor 1(Tfr1) mRNA in mucoepidermoid carcinoma of parotid gland and its relationship with prognosis.
From June 2013 to July 2015 in Tangshan Workers’ Hospital, 35 patients with mucoepidermoid carcinoma of parotid gland were selected. The relative expression of mTOR and Tfr1 mRNA in mucoepidermoid carcinoma of parotid gland was detected. The relationship between mTOR mRNA, Tfr1 mRNA and the clinicopathology and prognosis of mucoepidermoid carcinoma of parotid gland was analyzed using SPSS19.0 software package.
The relative expression levels of mTOR mRNA and Tfr1 mRNA in mucoepidermoid carcinoma of parotid gland were significantly higher than those in adjacent tissues(P<0.05). The relative expression of mTOR mRNA and Tfr1 mRNA was correlated with invasion depth, tumor grade, TNM stage and cervical lymphatic metastasis(P<0.05). The relative expressions of mTOR and Tfr1 in patients with good prognosis were significantly lower than those in patients with poor prognosis (P<0.05). The AUC of mTOR mRNA was 0.815, higher than that of Tfr1 mRNA(0.813). The AUC of mTOR mRNA combined with Tfr1 mRNA was 0.922, higher than that of mTOR mRNA and Tfr1 mRNA alone. Cox univariate and multivariate analysis showed that differentiation, TNM stage, mTOR mRNA and Tfr1 mRNA were closely related to poor prognosis of mucoepidermoid carcinoma of parotid gland.
The relative expression of mTOR mRNA and Tfr1 mRNA in patients with mucoepidermoid carcinoma of parotid gland was significantly increased, which can be used to evaluate the prognosis of patients.
