    Author: Sal'nikov LV, Mezentsev AI, Bedrin LM, Chernova AS.
    Journal: Med Radiol (Mosk); 1986 Mar; 31(3):20-4. PubMed ID: 3959794.
    Abstract:
    The paper is concerned with the results of radiation and combined therapy of 122 patients with Stage III-IV laryngeal cancer, divided into 2 groups: 74 controls and 48 patients of the study group. The patients of the study group received radiotherapy in combination with local administration of 5% solution of metronidazole in dimethyl sulfoxide. According to biopsy findings, the average concentration of metronidazole in tumor was 569.5 +/- 196 micrograms/g. Therapeutic results were evaluated by the degree of expression of tumor radiation injury and by direct and short-term results. A statistically significant increase in the frequency of Stage IV tumor radiation injury from 31.1 +/- 5.4% in the control group to 58.3 +/- 7.2% in the study group (P less than 0.05) was revealed. The direct and short-term therapeutic results indicate an increase in tumor radiation injury in the patients of the study group.
