[Experiences with cesium contact therapy in uterine cancer].

Till the end of 1969 contact therapy (CT) of the cervix and corpus carcinomas was performed with radium at the gynecological clinic of the Medical Academy Dresden. After taking out the radium of the gynecological CT we continued the therapy with cesium. Iitally, there were no experiences with respect to isodoses, periods of storage and efficiency on the tumor. On direct measurement of the provided cesium containers an essential higher dose rate than that of radium was found. This dose rate was twice the rate of radium at a distance of 3 cm. Thereupon the periods of storage were shortened half the time at constant carrier activities. A measurement of the radiation exposure of the bladder and the rectum was performed on priciple. In evaluating the patients radiated with cesium from 1970 to 1972 we discuss the results of the patients treated with radium from 1968 to 1970 by way of comparison. The 5-year healing quotients attained did not show any significant differences.
