General problems of the carcinoma of the cervix and presentation of a new circular applicator for the afterloading technique with the selectron

During our radiooncologic experience, we have learned the problems caused by insufficient information on the patient and his tumor. Histologic data, stage and a drawing of the extension of the tumor are generally submitted to the radiotherapeutist. This study is intended to remind that some other factors are important for the radiooncologic decision about local and temporal dose distribution, such as tumor size, endometrial extension to the fundus, frequency of metastases and recurrences, different histology/grading, and performed surgical technique/radicality. The vital importance of these factors is explained. A new circular applicator is presented for routine afterloading irradiation with the selectron. The applicator has proved to be useful in practice. The problems of the afterloading technique as against the radium technique are indicated, especially with regard to the dose rate in point A. (orig.)
