A total of 22 patients with leukemia (10 ALL [acute lymphocytic leukemia], 11 AML [acute myelogenic leukemia], 1 CML [chronic myelogenous leukemia]) have undergone allogeneic bone marrow transplantation (BMT). All patients received 900 cGy [grays] total body irradiation (TBI), in a single fraction, on the day preceding BMT. The first 11 patients were treated on a cobalt unit at a constant dose rate of 4.7 to 6.3 cGy/min. Six of these patients developed interstitial pneumonitis (IP). The clinical course of 3 patients, 2 with idiopathic and 1 with drug-induced pneumonitis, was mild and recovery was complete in all. The other 3 patients developed severe infectious IP and two died. The next 11 patients were treated with a sweeping beam technique on a 4 MV linear accelerator delivering a total tumor dose of 900 cGy at an average dose rate of 6.0-6.5 cGy/min but an instantaneous dose rate of 21.0-23.5 cGy/min. Eight patients developed severe IP. Five of these were idiopathic and 4 died. Three were infectious and all died. The fatality of interstitial pneumonitis appeared to be greater in the group treated with the sweeping beam technique.
