[Successful long-term treatment of multiple metastases from renal cell carcinoma: combination of stereotactically guided percutaneous single-dose convergent beam irradiation and surgery].
The case of a patient suffering from renal cell carcinoma and recurrent brain metastases shows how the survival period can be significantly prolonged by a combination of stereotactically guided percutaneous single-dose convergent beam irradiation and surgery. This 58-year-old man's left kidney was completely excised because of a renal cell carcinoma. After 18 months and 25 months, respectively, a right frontal brain metastasis was operated on. In the next 7 years, biannual MRI checks were carried out which successively showed five different brain metastases, each of which was immediately subjected to single-dose stereotactic irradiation (median dosage: 20 Gy prescribed to the 80% isodose). In the following 2 years, operations were carried out on two metastases which could not be treated by radiation because of their considerable size and partial compression of the ventricle. In the next 3 years, four more brain metastases were subjected to single-dose stereotactic irradiation. There were no metastases in the other organs. At present, the patient is in good clinical condition and mobile. A negative prognosis is usually delivered for patients suffering from renal cell carcinoma and brain metastasis. However, in individual cases, the survival period can be significantly prolonged by regular MRI examinations and a combination of neurosurgery and single-dose stereotactic irradiation.
