background : the brain is a rare site of metastases from ovarian cancer. limited data are available on prognostic factors, standard treatment, and survival. knowledge of clinical prognostic factors would help the management of patients with brain metastases. the aim of this study is to evaluate the impact of clinical factors and treatment modalities on survival in patients with brain metastases...
we present a rare case with history of neurological symptoms due to multiple brain metastases and no urological symptoms. during patient evaluation for primary tumor, transitional cell carcinoma (tcc) of left renal pelvis was found. the patient underwent gamma knife stereotactic radio-surgery for the metastatic brain lesions. radical nephroureterectomy was performed, and a 4-cycle course of pac...
Abstract Background: This study was done to define the role of Graded Prognostic Assessment (GPA) score for predicting overall survival in patients diagnosed with brain metastases undergoing Gamma-knife radiosurgery. Materials and methods: Patients diagnosed with brain metastases who were candidates for Gamma-knife radiosurgery entered this cross sectional study between 2003 and 2011. Clin...
60-year-old woman was treated for a brain metastasis. The patient received intensity-modulated radiation therapy (SIB-IMRT) dose of 30 Gy for the whole brain and 40 Gy delivered simultaneously to individual brain metastases in 10 fractions. The present report investigated the influence of applied novel prepared treatment plan, among others the fractionation protocol on the electroencephalogram ...
