We performed conformal radiotherapy on 130 cases of oral cancer in Iwate Medical University Hospital's Dental Medical Center from 2006 to 2012. We researched a number of cases in regards to gender, age distribution, primary site, histopathological diagnosis, TMN classification, course intent, combined chemotherapy, total irradiated dose, and various field of radation technique and area.
The following results were obtained:
1. The male-female ratio was 2.2:1. Peak age distribution was in the 60s for males and 70s for females.
2. The most common primary site was the tongue, and most patients were histopathologically diagnosed with squamous cell carcinoma.
3. According to TNM classification, T4 was 40.0%, T2 was 28.5% and T3 were 21.5% of all cases.
4. Intra-arterial infusion chemotherapy with concurrent radical radiotherapy was most performed.
5. As for the total irradiated dose, 40-49Gy was most prevalent and 60-69Gy followed.
6. The most performed radiation technique was two oblique fields, and 67.7% of radiation fields included primary and regional lymphnodes.
