[The expression of BUB1 in laryngeal squamous cell carcinoma and its clinical significance]
Objective:
To investigate the expression and clinical significance of BUB1 protein in laryngeal squa mous cell carcinoma (LSCC) tissues.
Method:
The expression of BUB1 protein was measured by immunohistochemistry (EliVision two steps) in 55 cases of LSCC tissues,30 cases of adjacent normal laryngeal mucosa tissues, the relationship of BUB1 expression with clinical pathologic factors in LSCC was also analyzed.
Result:
The positive rate of BUB1 protein in LSCC tissues (50.9%, 28/55) was significantly lower than that in adjacent normal laryngeal mucosa tissues (83.3%, 25/30), P < 0.01. The positive rate of BUB1 protein was correlated with differentiation grading and lymph node metastasis of LSCC (P < 0.05, respectively), but not with patient's sex, age, smoking, tumor site, T-stage and clinical stage(P > 0.05, respectively).
Conclusion:
The low expresssion of BUB1 protein is closely related to the tumorigenesis and development of LSCC, and can be a molecular marker for prognosticating metastasis and prognosis of LSCC.
