Abstract

The objective of this research is to find out the influencing factors to recur oral cancers. The outcomes of 85 patients(male:62 patients, female:23 patients)with oral cancer who were not treated any pre-operative radiotherapy, chemotherapy or previous oral surgery,other than routine dento-alveolar procedures and a recent diagnostic biopsy were analysed retrospectively. Actuarial (life tables)survival analysis showed the 5 year survival rate was 58%, 52% for male patients, 72%for female patients.The patients who were under 50 years old showed 71% of 5 year survival rate, 51% of 5 year survival rate were above 51 years old group.Patients who were treated with elective neck dissection showed better prognosis which were shown 73% of 5 year survival rate than not neck dissection which were reveal 45%of 5 year survival rate. In TNM stage of patients, advanced stage showed worse prognosis, but only N stage did not suggest to judge good prognosis. Most patients were treated under postoperative radiation therapy and showed better prognosis.
