Retrospective Study On The Influencing Factors Of Survival Rate After Treatments Of Oral Cancer

ABSTRACT

research is to find out the influencing factors to recur oral cancers. The outcomes of 85 patients(male62 patients, female23 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.
