Significance Of CEA And SA In Saliva Of Patients With Malignant Tumors Of Oral And Maxillofacial Region

Objection: To study the diagnostic value of carcinoembryonic antigen(CEA)and salic aside (SA) level in saliva of patients with malignant tumor. Method: ELLIS A method was adopted to determine the SA level and ENZYMIC method was used to determine the CEA level in saliva of 40 patients with malignant tumor,22 patients with benign tumor and 40 normal adults. Result: The results showed that SA and CEA in saliva of patients with oral and maxillofacial cancer were significantly higher than those in the saliva of patients with benign and normal adults(p<0.01);also there were no diference in CEA and SA between the patients with benign tumor and normal adults (p>0.05).Conclusion: CEA and SA level in sialiva of patients with maliganat tumor group is much higher than benign tumor and normal group. Sialiva CEA and SA being used as tumor marker for an early diagnosis of malignant tumors in oral and maxillofacial region may play an assistant role.
