[Results of radio- and chemoradiotherapy of malignant nasopharyngeal neoplasms].

: Moving sectoral irradiation was given to 40 patients with primary (23) and recurring (17) rectal tumors. The patients received treatment 3 times a week by 2 daily fractions of 2.5 Gy with 4 h intervals. Better short-term results in primary and recurring tumors and the reduction of therapy duration were shown in comparing these patients with the control group of patients who were irradiated for 5 days a week by a single dose of 2 Gy.
