[Relation of the effectiveness of radiotherapy of cervix cancer to the magnitude of the absorbed dose].
The results of therapy of 949 patients with cervical cancer are analysed. Therapy was provided in the form of a concomitant method, 60Co agents with low activity were used in intracavitary irradiation. It has been established that doses of 50-70 Gy ensure high 5-year survival rates of patients with Stage I cervical cancer. In patients with Stage II and Stage III cervical cancer survival rates were the highest within the range of 50-70 Gy. A further increase in the absorbed dose level deteriorated the survival rates of the patients, the frequency of local tumor control was not elevated. It is recommended that optimum dose levels be adhered to even during treatment of patients with disseminated cervical cancer.
