title: Expectation of aplastic anemia following radiotherapy for malignancy.
abstract: In Japan after 1969, 11 cases of aplastic anemia following radiotherapy for malignant disease were detected. The population at risk in irradiated patients was estimated at 674, 664 man-years. The expected cases of aplastic anemia in this population were calculated as 10.1. There is no statistically significant difference between the expected and the observed values.
