Abstract:
OBJECTIVE:To investigate osteopontin (OPN) expression in plasma and tissue of patients with layngeal squamous cell carcinoma and analyze its role in invasion, metastasis, and clinical significance in laryngeal quamous cell carcinoma.
METHOD:Enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry were used to detect expression of OPN in plasma and tissue of 60 cases of laryngeal squamous cell carcinoma, 20 cases of adjacent normal laryngeal tissue and 20 cases of plasma from healthy subjects.
RESULT:The expression of plasma OPN was closely correlated with clinical stage and cervical lymphatic metastasis in laryngeal squamous cell carcinoma (P < 0.05), but no significant correlation with the tumor location, pathological grade, gender and age (P > 0.05). The expression of OPN increased in plasma during cancer development: laryngeal squamous cell carcinoma (38.089 ± 9.225) ng/ml, healthy subjects (18.563 ± 9.308) ng/ml. There was a significant difference between the groups (P < 0.05). The expression of OPN in tissue was closely correlated with clinical stage (P < 0.05), pathological grade (P < 0.05) and cervical lymphatic metastasis (P < 0.05) in laryngeal squamous cell carcinoma adjacent atypical hyperplastic epithelium and carcinoma. The expression of OPN increased in tissue during cancer development: laryngeal squamous cell carcinoma (56.67%), adjacent normal laryngeal tissue (15.00%). There was a significant difference between the groups (P < 0.05). Elevated expression of plasma OPN is positively correlated with the expression of OPN in tissue in laryngeal squamous cell carcinoma patients (r = 0. 871, P < 0.05).
CONCLUSION:OPN plays an important role in the infiltration, metastasis and carcinogenesis in laryngeal squamous cell carcinoma. Combination of serum OPN, tissue OPN detection can be used as diagnostic and surveillance indicators for laryngeal squamous cell carcinoma infiltration and metastasis.
