Abstract:
Objective To detect the expressions of Six1 ,TGF‐βand their common induced VEGF‐C in human laryngeal squa‐mous cell carcinoma ,and to explore their significance in the occurrence ,development ,metastasis and prognosis of laryngeal squa‐mous cell carcinoma .Methods The clinical data and preserved paraffin samples of 96 patients with laryngeal squamous cell carci‐noma confirmed by postoperative pathology were collected .The protein expression of Six1 ,TGF‐βand VEGF‐C was determined by adopting immunohistochemistry and Western blotting .Results The positive expression rates of Six1 ,TGF‐β and VEGF‐C in the laryngel squamous cell carcinoma tissue samples were 84 .4% (81/96) ,89 .6% (86/96)and 91 .7% (88/96)respectively .The positive expression rate of Six1 was significantly higher in the patients with poor differentiation and lymph node metastasis ;the positive ex‐pression rate of TGF‐βwas significantly higher in the patients with lymph node metastasis and had no relationship with the degree of differentiation ;the positive expression rate of VEGF‐C was significantly higher in the patients with poor differentiation and lymph node metastasis ;there was a positive correlation between expression of Six 1 and VEGF‐C in the laryngel squamous cell canc‐er tissue .Conclusion The high expression of Six1 ,TGF‐βand VEGF‐C may promote lymphatic metastasis of laryngeal squamous cell carcinoma .Six1 expression may be one of the important influencing factors of the expression change of VEGF‐C .The combined detection of Six1 ,TGF‐βand VEGF‐C has an important clinical significance for judging the metastasis and prognosis of LSCC .
