Adenylyl Cyclase-Associated Protein 1 in the Development of Head and Neck Squamous Cell Carcinomas

Resumo

We compared the content of adenylyl cyclase-associated protein 1 (CAP1) in the blood and tissues of patients with head and neck squamous cell carcinomas (with and without regional metastases), patients with chronic inflammatory diseases aggravated by laryngeal and laryngopharyngeal dysplasia, and healthy individuals. The data suggest that serum CAP1 concentration correlated with the depth of primary tumor invasion and the presence of regional metastases. In cancer patients, the serum level of CAP1 was lower than in patients with laryngeal and laryngopharyngeal dysplasia, which can be of importance for differential and timely diagnostics of malignant tumors.
