RADIOSURGICAL TREATMENT FOR BRAIN METASTASES OF OVARIAN CANCER
Introduction. Radiosurgical treatment is the method of choice for brain metastases. In clinical practice, there are tumors with a relatively small frequency of secondary brain damage, for which the use of stereotactic radiosurgery has not been studied enough. One example of such diseases is malignant tumors of the female reproductive system.Materials and methods. We described the application of stereotactic radiosurgery of ovarian cancer metastases to the brain using a three-fold hypofractionated stereotactic radiosurgery. We resorted to this method in order to reduce the negative effect on the functional area of the brain and preserve the performance of radiation in the treatment of metastasis located in the subcortical nuclei. To evaluate the results, were performed magnetic resonance imaging and volumetry of pathological volume in the program for planning stereotactic radiosurgery Leksell Gamma plan® 10.1.Results. Long term local control was observed on the part of all irradiated tumors with the same results of single irradiation and hypofractionated radiosurgery. Discussion. If there is a restriction to conduct a stereotactic radiosurgery associated with the localization of a pathological focus in the eloquent zone of the brain, it is possible to irradiate it in the hypofractionation mode. The method provides local control of tumor growth without a high risk of radiation toxicity.
