Primary oral squamous cell carcinoma: a review of 92 cases

PURPOSE: This is a retrospective review of 92 cases of oral squamous cell carcinoma treated by one department of oral and maxillofacial surgery. PATIENTS AND METHODS: The medical records of 92 patients with oral squamous cell carcinoma were reviewed, and standard epidemiologic data were obtained. In addition, cases were identified as to site, stage, risk behavior, histologic classification, primary and secondary surgical treatment, adjunctive therapy, and survival rates. RESULTS: The results indicate a higher-than-predicted 2-year survival rate. The association between alcohol and tobacco consumption and incidence of disease is supported. There was a correlation between tumor size and survival rate, but no correlation between histologic classification and prognosis. CONCLUSION: Mortality increases in relation to the stage at which the diagnosis of oral squamous cell carcinoma is made. Patients with stage III or IV lesions have a much poorer prognosis than those with stage I or II lesions. However, histologic classification and prognosis were not correlated.
