Abstract
Oral cavity cancer belongs to head-and-neck squamous cell carcinoma group. The purpose of the study was to assess the levels of certain proteins in a tumour and surgical margin in a group of patients with oral cavity cancer. The levels of DAPK1, MGMT, CDH1, SFRP1, SFRP2, RORA, TIMP3, p16, APC and RASSF1 proteins were measured by ELISA in tissue homogenates. The protein levels of DAPK1, MGMT, CDH1, SFRP2 and RASSF1 were significantly higher in tumour tissue than in the margin, contrary to TIMP3 which was lower in the tumour itself. DAPK1 level in the tumour was significantly higher in females than in males, the MGMT and p16 levels were lower in the tumours with lymph node metastasis (N1 + N2) than in N0 samples. The CDH1 expression was higher in a group with smoking habits, whereas TIMP3 was lower in this group. Changes in the levels of proteins in tumour and surgical margin may be either reflective of tumour occurrence and development, or they might be also responsible for the progress and reoccurrence of the disease. Levels of the studied proteins might be good prognostic factors; however, further studies are required.
