[Concurrent radiochemotherapy in the treatment of squamous cell oral and oropharyngeal cancer]

Abstract

The aim of this study was to evaluate the end results of the radiochemotherapy of 237 patients with squamous cell carcinoma of oral mucosa (locally advanced, stage III-IV, - 134; 56.4%, and metastases to regional lymph nodes of the neck - 91; 38.4%) carried out at the Center's Clinic. Interstitial neutron (252 californium) plus polychemotherapy was given to 26 (11%) (group 1); neutron + distant radio + polychemotherapy - 34 (14 %) (group 2); distant fractionated radiotherapy + polychemotherapy - 177 (75%) (group 3). Complete response was reported in 190 (80.2%); partial - 44 (18.6%) and stabilization - 3 (1.3%). Overall response was 98.8%; 5-year survival - 64.5 +/- 3.3%, irrespective of tumor site, grade and method of treatment. Concomitant modality proved highly effective, free from toxic and functional or cosmetic harm.
