Expression of ezrin and moesin related to invasion, metastasis and prognosis of laryngeal squamous cell carcinoma

We examined the expression of ezrin and moesin in laryngeal squamous cell carcinoma (LSCC) and their correlation with patient clinicopathological characteristics and overall survival. Immunohistochemical staining and reverse transcription-polymerase chain reaction (RT-PCR) for ezrin and moesin were applied to 60 carcinoma tissues, adjacent normal tissues, and 33 metastatic lymph nodes. Survival functions were estimated using the Kaplan-Meier method and compared by the log-rank test. RT-PCR demonstrated that the intensity ratios of ezrin and moesin to β-actin were higher in LSCC than in adjacent normal mucous membrane (P 0.05). Patients with negative ezrin and moesin expression had a significantly longer overall survival time compared to patients with moderate and intense ezrin and moesin expression (P We examined the expression of ezrin and moesin in laryngeal squamous cell carcinoma (LSCC) and their correlation with patient clinicopathological characteristics and overall survival.

Patients with negative ezrin and moesin expression had a significantly longer overall survival time compared to patients with moderate and intense ezrin and moesin expression (P< 0.001, P < 0.05). Ezrin and moesin expression is related to LSCC invasion and metastasis, and may be important molecular markers for predicting prognosis and therapeutic targets in LSCC patients.
