Abstract :

The study was conducted on 35 patients who were diagnosed with squamous cell carcinoma of the gingiva/alveolar ridge mucosa in the National Hospital of Odonto-Stomatology in Hanoi and Hanoi Medical University Hospital. This study described the clinical and para-clinical manifestations of squamous cell carcinoma of the gingiva/alveolar ridge mucosa in these 35 patients. It was a retrospective study to review patients record and direct interview. The results show that males is more than a half of pateints (18/35; 51.4%). The age ranged from 26 to 79 years with the mean age of 49.1 years. The proportion of smoker was 37.1%. The betel chewers accounted for 14.3%. The tumor was more common in the lower jaw (57.1%) than the upper jaw (42.9%). The posterior dental sites (74.3%) were more likely to have tumor than the anterior sites (25.7%). Almost of the tumor size was T4 (80.0%), follow with T2 (17.1%) and T1 (2.9%). Nodal metastasis was assessed as the highest stage with 74%, while N1 and N2 was lower 14.3% and 11.4%. The most commonly used surgical method is tumor resection with neck dissection and reconstruction (74.2%), followed by with neck dissection (22.9%) and sole tumor resection (2.9%). After surgery, recurrence rate was 25.7%, in which the local tumor recurrence was higher than the recurrence nodal level (77.8% vs 22.2%, p <0.05). Average survival time after surgery was 57.8 months. Five-year survival was high with 66.4% of patients. The 3-year survival rate of patients without node was higher than that of nodal metastasis group (80.6% vs. 20.8%, p <0.05). Patients should be screened before the age of 50. When detecting surgical intervention in time to limit lymph node metastasis to improve the survival of the patient.
