ABSTRACT
OBJECTIVE@#To study whether programmed cell death 4 (PDCD4) is involved in the development and progression of laryngeal squamous cell carcinomas (LSCC).@*METHOD@#The expressions of PDCD4 protein were examined by immunohistochemical staining and Western blot in LSCC tissues and their surrounding laryngeal normal mucosa tissues.@*RESULT@#The positive rate of PDCD4 protein in LSCC was significantly lower than that in the laryngeal normal mucosa tissues by immunohistochemical staining (P<0.01). No correlation was found between positive expression of PDCD4 and gender, age, tumor site, TNM stage, but there was significant correlation between positive expression of PDCD4 from differentiation grading and lymphatic matastasis. Meanwhile,we got the similar results by Western blot (P<0.01).@*CONCLUSION@#The low expression of PDCD4 protein is closely related to the development and progression of LSCC. PDCD4 might be a novel molecular marker for prognosticating metastases and prognosis of LSCC.
