1) There were 67 primary mortalities out of 1,974 cases of the cervical carcinoma who were treated by radiation at the Dept. of Obstetrics and Gynecology, Okayama University, during the recent 21 years (average primary mortality: 3.4%) 2) The first cause of death is infection which has greater part of primary mortality, and peritonitis is dominant. The second cause of death is bleeding and the third is death from the advanced cachexia. 3) From 1934 to 1951, we generally gave them radiumtherapy after roentogentherapy and primary death occurred more frequently at the time of radiumtherapy than at roentogentherapy. From 1952, radiotherapy has been performed by Yagi-Takeda's method which had no influences on the primary mortality. 4) Primary mortality increases with the progress of the clinical stage of carcinoma and is 1.3% in the I & II stage, while 4.3% in the III & IV stage. The primary mortality has no relations to the site of the carcinoma, the ages and the frequency of parturition of the patients. Primary mortality was remarkably high during and within a few years after the World War II.
