Abstract
Combined radiotherapy of patients with cervical carcinoma of stages II b and IIIb was conducted. Hypoxia (8.0-8.5 % of O2 in the respiratory mixture) was used in microfractionated (2 Gy) irradiation of metastati c spreading zones. When irradiating under conditions of hypoxia, the n umber of fracions was brought up to 28 as compared to 20 in control. D espite a 40 %-increase of the dose, seriousness of radiation reactions and remote injuries remained al the same level. It is found that pati ents endure well the respiratory mixture for 6 min. necessary for irra diation.
