Expression of Lymphoma-2 Gene and NF-κB in Human Adenoid Cystic Carcinoma Tissue and Its Relation with Disease Prognosis

Abstract

Background: Adenoid cystic carcinoma (ACC) is a common tumor of the head and neck. It is characterized by slow growth, strong invasiveness, easy recurrence and distant organ metastasis. Bcl-2 and NF-κB are indicated to relate to tumor growth, proliferation and apoptosis. This study aims to analyze the relationship between Bcl-2, NF-κB and ACC. Methods: With ELISA method to detect Bcl-2 and NF-κB expression in the blood of patients with ACC, patients with benign adenoma and healthy controls, and the expression of Bcl-2 and NF-κB in tissues was detected by immunohistochemistry, and their relationship with ACC was analyzed. relevance. Relationships between clinicopathological features. Results: The levels of Bcl-2 (4.16±1.34 ng/ml) and NF-κB (4.47 ± 1.37 ng/ml) as well as positive rates of Bcl-2 and NF-κB (87.5% and 85%) were significantly elevated in the ACC group (P <0.05). Bcl-2 was positively correlated with NF-κB (P <0.05). Of note, Bcl-2 and NF-κB expressions were correlated with the incidence frequency, histological type, clinical stage, lymph node metastasis and distant metastasis of ACC patients (P < 0.05) as the distant metastasis is an independent risk factor. Conclusion: In summary, Bcl-2 and NF-κB expression in ACC patients is associated with the clinicopathological features of ACC.
