title: [Combined modality treatment of locally advanced oral and oropharyngeal cancer following primary radiotherapy with and without taxol radiosenzitization]
abstract: AIM: To determine the effect of radiosensitization with Taxol and multimodality treatments on the survival of advanced oral and oropharyngeal cancer. Patients, methods: 56 patients with St. III-IV oral or oropharyngeal cancer were treated with external beam radiotherapy; 26 of them were sensitized by low-dose paxlitaxel and 30 were irradiated traditionally. The median follow up was 23 months (17-36). Endpoints of the study were: response to radiotherapy, progression-free and overall survival and the results of surgery and chemotherapy following radiation. RESULTS: 73.3% (41/56) of treatments resulted in CR or PR with median 10 months (0-33) progression-free and 14 months (4-33) overall survival. There was no significant difference between the radiosensitized and traditional radiotherapy group (p=0.6). The survival was significantly influenced by the stage of tumor and the response to primary radiotherapy. Seven (38.9%) of 16 patients treated also by either surgery or chemotherapy for recurrent or residual disease are free of cancer, 6 (35%) alive with tumor and 5 (26.1%) died with median survivals of 21, 20.5 and 18 months, respectively. Those treated only with radiotherapy with or without sensitization are free of cancer in 31.6%, alive with cancer 5.3%, died 63.2%. CONCLUSION: There were significant correlation between tumor stage, response to radiotherapy and combined modality treatment, and surival. The radiosensitizing effect of Taxol was not obvious so far, it may be apparent in the future by analyzing the long term survival data.
