title: [A retrospective study on the importance of preoperative control in the prognosis of spinocellular carcinoma of the oral cavity].
abstract: Surgical treatment of advanced forms of spinocellular carcinoma of the oral cavity (stages 3-4) has been integrated for a number of years with cycles of chemo- and/or radiotherapy both before and after surgery. This chemo-radio-surgical therapeutic protocol consists of four distinct stages, separated by precise treatment-free intervals, which enable the best efficacy to be achieved through synergy. A total of 60 patients were treated by our Ward using this protocol during the period March 1988-June 1992. At the time of surgery a complete negative outcome in the histological picture (pTO) was observed in 40% of cases; lesions had not regressed on only 16% of patients. A retrospective type study has been carried out using Kaplan-Meier's statistical analysis to evaluate the prognostic factors in this population: a significant correlation was found between disease-free time and survival, calculated at 40 months from the completion of the protocol, and histopathological TNM. Non correlation was found with clinical TNM: therefore, rather than the extent of the lesion at the time of diagnosis, its control during preoperative stages appears to be the major prognostic factor.
