[Radiotherapy and chemoradiotherapy of neglected forms of malignant oropharyngeal tumors].

Open-field gamma-beam therapy using grid filters was used for 53 patients with Stage III-III stomatopharyngeal tumors. Besides, to compare therapeutic efficacy the 2nd group was taken (52 persons with Stage III-IV) where chemotherapy was used simultaneously. Single and summary radiation doses did not lower. A chemotherapeutic agent dose was equal to 1/2 up to 2/3 of the standard one. Powerful substitution and hemostimulation therapy and a great variety of drugs were employed not to induce deep changes of hemopoiesis and immunosuppression. A single focal dose in gamma-beam therapy varied from 1.6 to 2.5 Gy, the summary dose from 55 to 70 Gy depending on the stage of disease and the histological structure of a tumor. The prescription of one or another chemotherapeutic agent was mainly determined by the morphological structure of a tumor.
