抄録

We prefer to apply a single large dose irradiation method in radiotherapy because of its remarkable radiation effect and no significant alternation in the patient's immunologic capacity.<BR>In this report, we treated two cases with carcinoma of main bronchi preoperatively by this method and could obtain the favorable results.<BR>The former was irradiated once a week for 3 times (total 3000 rads) and no cancer cell was found in the speciment of the removed lung, though it was diagnosed as early carcinoma of the main bronchi prior to irradiation.<BR>After the single large dose irradiation, the numbers of lymphocytes and T cells in the peripheral blood did not decrease, and blastoid formation rate of lymphocyte as well as strengten of PPD skin test were enhanced.<BR>The latter was irradiated only once (1000 rads) and the specimen of the removed lung showed Grade II radio-change by criteria fo radiation effect (Oboshi, S., 1971).<BR>No radiation injury was noted during the irradiation in both cases.<BR>This radiation method has some advantages and is more effective than conventional one because of shortness of the over all time and no significant immunosuppressive effect in tumor-bearing host.
