Abstract
During the 10-year period from 2004 to 2013, 150 cases of oral region squamous cell carcinoma were treated radically at our department; these cases were reviewed and clinically analyzed. The male-to-female ratio was 1.7：1 and the mean age was 65.3 years. Many cases were referrals from dental clinics (46.0％), whereas only 8.7％ of cases were direct presentations. The majority of patients (51.3％) were admitted within 3 months from the onset of symptoms. Pain was the most common symptom (39.3％), with the tongue being the most common site (54.7％). According to the TNM classification of UICC (2009), the patients were classified as follows: Tis, 3.3％; T1, 30.0％; T2, 37.3％; T3, 5.3％; T4, 24.0％; N0, 66.0％; N1, 15.3％; N2, 18.7％; N3, 0％; and M1, 0％. The patients were clinically staged as follows: Stage 0, 3.3％; Stage I, 28.0％; Stage II, 24.7％; Stage III, 12.7％; and Stage IV, 31.3％. The treatment methods were as follows: surgery, 60.0％; radiotherapy, 1.3％; surgery with chemotherapy, 4.0％; surgery with radiotherapy, 2.0％; chemotherapy with radiotherapy, 30.0％; and surgery with chemotherapy and radiotherapy, 2.7％. Kaplan-Meier survival curves indicated a 5-year survival rate of 84.1％.
