[Radiation therapy of malignant neoplasms of the middle ear after nonradical surgical interventions].

The paper is concerned with the short- and long-term results of gamma-beam therapy and chemo- and radiotherapy in 109 patients with malignant middle ear tumors after nonradical surgical interventions. A single focal dose was 2-2.5 Gy, a summary dose varied within 60-80 Gy with relation to the degree of dissemination, growth type and tumor histological structure. A 3-year survival rate was 41.1%, a 5-year survival rate was 21%.
