Abstract | OBJECTIVE: METHOD: Streptavidinbiotin peroxidase complex (SABC) immunohistochemical method was used to study the expression of CD44V6 and PCNA in 35 cases with squamous cell carcinoma in eyes, 20 cases with papilloma, 11 cases with normal eyelid tissue. RESULTS: The CD44V6 positive rate was 62.9% (22/35) in squamous cell carcinomas in eyes, 15.0% (3/20) in papillomas, none in 11 cases with normal eyelid tissue. The positive expression rate of CD44V6 in the malignant group was significantly higher than that in the benign and control group, and the positive expression rate of CD44V6 in cases with metastasis was significantly higher than that without metastasis. PCNA labeling index (PI) in the CD44V6 positive expression of tumors was significantly higher than that in the CD44V6 negative expression of tumors (t = 20.21, P < 0.01). CONCLUSIONS: The over-expression of CD44V6 is correlated with the progress and metastasis of SCC. CD44V6 protein expression is correlated positively with PCNA expression, and the evaluation of both CD44V6 and PCNA is useful for predicting the prognosis.
