OBJECTIVE: To study the expression of SKP2 and MRP-1/CD9 protein in glottic cancer and adjacent tissues, and to analyze its significance for a safe surgical margin.
METHOD: Thirty-eight cases of glottic squamous cell carcinoma were studied for its cancer tissue, tissue 2 mm, 5 mm, and 10 mm away from cancer, and 10 cases of vocal cord polyp were served as control. SKP2 and MRP-1/CD9 protein were examined by immunohistochemical method.
RESULT: The positive expression of SKP2 proteins decreased in sequence of polyp mucosa, those adjacent to carcinoma (10 mm, 5 mm, 2 mm ) and cancer tissue, and there was significant difference between them (P < 0.05); On the contrary, the positive expression of the MRP-1/CD9 proteins increased in sequence of polypous mucosa, those adjacent to carcinoma (10 mm, 5 mm, 2 mm) and cancer tissue,and there was significant difference between them (P < 0.05).
CONCLUSION: SKP2 and MRP-1/CD may act as the reference index for judging the biological specialty of LSCC. It is appropriate to regard 5 mm or above 5 mm away from tumors as a safe margin for surgical treatment of glottic carcinoma.
