Expressions of cyclin D1 and p16 in hypopharyngeal squamous cell carcinoma and their clinical significance / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To study the expressions of Cyclin D1 and p16 proteins in hypopharyngeal squamous cell carcinoma and their clinical significance.@*METHOD@#Immunohistochemical technology (P-V) was applied to detect the expression of Cyclin D1 and p16 in 36 cases of hypopharyngeal squamous cell carcinoma and 10 cases of normal epithelium.@*RESULT@#(1) The expression of cyclin D1 in the tumorous cell was significantly higher than that in normal epithelium (P 0.05); (3) There was correlation between the expression of Cyclin D1 and the expression of p16 (r(s) = -0.420, P < 0.05).@*CONCLUSION@#The over-expression of Cyclin D1 and the under-expression of p16 may play a significant role in the occurrence incidence and development of hypopharyngeal squamous cell carcinoma, and may be important indicators for cervical lymph node metastases.
