title: [Possibilities of isodose distribution in afterloading contact therapy of non-operated uterine cancer using an applicator tube and a point-shaped radiation source].
abstract: For the contact radiotherapy according to the afterloading-procedure of patients with cervical and endometrial carcinomas isodose plans are represented, that are standardized to the lengths of uterus probes and adapted to tumor stages and are determined by an applicator tube lying centrally within the uterine cavity. By an additional lead screening of the vaginal applicator a dose reduction can be attained by the factor 1.6 or 1.4 in the critical organs bladder and rectum, which are relevant for this therapeutic form. An uncritical inclusion of the vagina into the target volume of contact therapy, that is not justified by tumor invasion, should not be carried out, knowing the higher complication rate at the critical organs.
