Abstract:
Objective:To investigate the expression of collagen typeⅠ(ColⅠ),collagen typeⅣ(ColⅣ)and fibronectin(Fn)in laryngeal squamous cell carcinomas(LSCC)and their pathobiological relationship with invasion and metastasis of tumor.Method:The expression of ColⅠ,Col Ⅳ and Fn was detected by immunohistochemistry method in normal tissue of latero-carcinoma and tissue of carcinoma in 60 specimens of LSCC.Integral optical density(iOD)was detected by image analysis of computer and was analyzed by SPSS13.O.Result:The expression of ColⅠ was obvious and integrity.The expression of Col Ⅳ and Fn of basal membrane was like intact line-shape appearance and Fn of interstitial substance appeared like a complete network in the normal tissue f latero-carcinoma.Their expression decreased gradually and their integrity was broken and disappeared gradually from well to poorly differentiated LSCC.Their expressions also fell off with the tumor size,clinical stage and cervical lymphatic etastasis gradually and consistently in LSCC.Their variances were statistical significance separately(P＜0.05 or P＜0.01).Conclusion:The expression of ColⅠ,ColⅣand Fn was closely related to tumor invasion,the regional lymph node metastasis and other some pathobiological features in LSCC.A detection of ColⅠ,ColⅣ and Fn as of definite significance on a better comprehension of the possibility of metastasis,choice of surgery and prognosis.
