[Dose multifractionation in radiotherapy of lung cancer of different histological types]

A study was made of immediate and short-term results of multifractionated radiotherapy of 120 patients with inoperable lung cancer. On discontinuation of radiotherapy the frequency of complete and pronounced tumor regression was significantly higher in radiosensitive small-cell lung carcinoma whereas during radiation exposure the correlation between a degree of tumor regression and tumor histological structure was absent as a result of an increase in the number of primary local cure in patients with squamous-cell and glandular carcinoma. A study of short-term therapeutic results confirmed the efficacy of the use of multifractionated irradiation in all main histological types of lung cancer.
