title: [Radiotherapy, using metronidazole, of regional lymph node metastases of cancer of the oral mucosa].
abstract: Altogether 67 patients with oral mucosa cancer metastases to the regional lymph nodes were given a split course of gamma-beam therapy with traditional dose fractionation and dynamic fractionation. Radiotherapy in the presence of metronidazole radiosensitization was given to 40 patients. Metronidazole was administered per os 3 = 4 h before irradiation with fractions I, III and V of each phase of a split course. A single dose of metronidazole was 5 g/m2, a summary dose 30 g/m2. Radiotherapy with metronidazole resulted in a 2-year cure of 17.5 +/- 6% of the patients. The therapy was the most effective in patients with metastases of diameter up to 2 cm. The results of therapy of oral mucosa cancer metastases to the regional lymph nodes were better in the use of the dynamic fractionation regimen.
