Radiation therapy is given through the tandem and ovoid applicator by placing radioactive capsules inside the hollow portions of the applicator. Placement of the radioactive capsules does not cause discomfort. The length of time that a patient has to remain in the hospital with the tandem and ovoid applicator in place depends on the situation. In most cases the applicator stays in for 40 to 48 hours. Radiotherapy is usually given with both external beam irradiation and internal implantation.
Most patients receive three separate internal implantation treatments, separated by a week.
The goal of internal implantation in this setting is to deliver a boost dose of radiation to the tissues near the upper part of the vagina. This kind of internal implantation radiotherapy is done in a special room in the radiation oncology clinic. The procedure begins by positioning the patient on a her back on a comfortable bed. A plastic applicator is placed in the vagina. The applicator is fitted to the vagina so there is little discomfort.
