ASSESSMENT OF THE INFLUENCE OF THE METHOD OF ELIMINATING THE DEFECT IN THE TREATMENT OF SQUAMOUS CELL CARCINOMA OF THE ORAL CAVITY ON THE COMPLETENESS OF THE COMBINED / COMPLEX TREATMENT
The aim of this work is to assess the influence of the method for eliminating the defect in the surgical treatment of squamous cell carcinoma of the oral cavity on the completeness of the combined / complex treatment. A retrospective analysis of the medical records of 114 patients with III and IV stages of the disease who underwent surgical treatment on the basis of the Leningrad Regional Clinical Oncological Dispensary was carried out. To remove tumors, a transoral, combined approach through the neck and mouth and an approach with mandibulectomy were used; all patients underwent a cervical dissection. Depending on the methods of elimination of defects formed after removal of tumors of the oral cavity, the patients were divided into 3 groups: local tissues (MT) were used to eliminate the defect in the oral cavity; regional flaps (RL); free revascularized autografts (CPA). 72.7% of patients in the MT group received adjuvant treatment. When using regional flaps, 56.2% completed the combined / complex treatment. In the group using revascularized flaps, 46 patients (64.7%) received adjuvant treatment. The result of this study was the absence of statistically significant differences in the frequency of receiving adjuvant treatment depending on the method of plastic surgery. Thus, the plastic technique does not affect the completeness of the combined / complex treatment and does not reduce oncological results, and the use of complex reconstructive techniques with relatively high rates of complications does not worsen the oncological prognosis.
