[Clinical study of renal cell carcinoma with brain metastasis].
Of 130 cases with renal cell carcinoma treated at Cancer Institute Hospital from January, 1981 to December, 1992, 14 (10.6%) developed brain metastasis, 12 of whom had had preceding pulmonary metastasis. Interval between the initial treatment of the primary lesion (nephrectomy in 13, embolization in 1) and the diagnosis of brain metastasis ranged 0 to 57 months with a median of 11 months. Twelve patients had clinical symptoms such as headache, vomiting, paralysis or disturbance of consciousness. Eleven patients were treated with external beam irradiation (30-60 Gy linear accelerator). Only 3 (30%) of 10 patients with measurable lesion on CT scan achieved PR but 6 (66.7%) of 9 had symptomatic improvement. Especially, chronic intracranial hypertension such as headache and vomiting disappeared in 5 (83.3%) of 6. Average survival period and one year survival after the diagnosis of brain metastasis were 5 months and 14.3%. Although most of the patients with brain metastasis died of the progression of other organ metastasis, radiation therapy for brain metastasis was useful to palliate the agonizing symptoms.
