The goal of this review is to summarize the rationale for and feasibility of hippocampal sparing techniques during brain irradiation. Radiotherapy is the most effective non-surgical treatment of brain tumors and with the improvement in overall survival for these patients over the last few decades, there is an effort to minimize potential adverse effects(More)
BACKGROUND The hippocampus is considered as the main radiosensitive brain structure responsible for postradiotherapy cognitive decline. We prospectively assessed correlation of memory change to hippocampal N-acetylaspartate (h-tNAA) concentration, a neuronal density and viability marker, by (1)H-MR spectroscopy focused on the hippocampus. METHODS Patients(More)
BACKGROUND Stereotactic body radiation therapy (SBRT) is well feasible and effective method for treatment of colorectal cancer liver metastases. MATERIALS AND METHODS From September 2009 to December 2011, 11 patients with 15 inoperable liver metastases of colorectal cancer were treated by SBRT using Varian Clinac iX linear accelerator. We treated 6 men(More)
BACKGROUND AND PURPOSE The aim of this prospective study is to evaluate post-whole brain radiotherapy (WBRT) changes in hippocampal concentration of N-acetylaspartate (h-tNAA) as a marker of neuronal loss and to correlate those changes to neurocognitive function. MATERIAL AND METHODS Thirty-five patients with brain metastases underwent baseline single(More)
PURPOSE To present a new technique of craniospinal irradiation as a postoperative prophylactic treatment in patients with intracranial ependymomas being at risk for relapse. PATIENTS AND METHODS In the last 3 years, 9 pediatric patients under 15 years of age with grade 2-4 ependymomas located infratentorially received postoperative craniospinal axis(More)
Surgical resection is the mainstay of gastric or gastroesophageal junction cancer treatment and has curative potential for patients with early-stage disease. In order to improve the poor survival rates, there are two complementary treatment strategies used at most - perioperative chemotherapy based on UK Magic trial or adjuvant chemoradiation based on(More)
In many ongoing clinical trials, new strategies for radiotherapy of brain metastases are currently being investigated. A post surgical focal cavity stereotactic radiosurgery and the developing role of a hippocampal-sparing whole brain radiotherapy are of the highest importance. The evaluation of spatial patterns of metastases failure after radiotherapy is a(More)
BACKGROUND Many prognostic indexes are available for patients with brain metastases in order to estimate remaining lifetime before selection of appropriate treatment including palliative radiotherapy. Their routine utilization is often deprecated for their complexity. We developed a practical tool based on widely available spreadsheet editors for(More)
