Impact of Including Peritumoral Edema in Radiotherapy Target Volume on Patterns of Failure in Glioblastoma following Temozolomide-based Chemoradiotherapy
We assessed the impact of including peritumoral edema in radiotherapy volumes on recurrence patterns among glioblastoma multiforme (GBM) patients treated with standard chemoradiotherapy (CRT). We analyzed 167 patients with histologically confirmed GBM who received temozolomide (TMZ)-based CRT between May 2006 and November 2012. The study cohort was divided into edema (+) (n = 130) and edema (-)...
متن کاملPostoperative chemoradiotherapy for gastric cancer.
BACKGROUND We report the results of postoperative chemoradiotherapy after curative resection in gastric cancer patients. PATIENTS AND METHODS Patients with gastric cancer staged IB to IV(M0) were treated with chemoradiotherapy after curative resection with extensive (D2) lymph node dissection. Nodal metastases were observed in 261 (90%) patients. The chemotherapy consisted of fluorouracil 400...
متن کاملPseudoprogression following chemoradiotherapy for glioblastoma multiforme.
PURPOSE Pseudoprogression (psPD) is now recognised following radiotherapy with concurrent temozolomide (RT/TMZ) for glioblastoma multiforme (GBM). The aim of this study was to determine the incidence of psPD following RT/TMZ and the effect of psPD on prognosis. MATERIALS/METHODS All patients receiving RT/TMZ for newly diagnosed GBM were identified from a prospective database. Clinical and rad...
متن کاملVolume Target Delineation for Brain Tumor in Mri Images Using Active Contour Segmentation Method
Radiotherapy is a tumor treatment process using high dose of radiation. Hence, it is essential that radiotherapy is carefully planned with a Treatment Planning System (TPS). The first step in TPS is delineation that aims to get a better picture of the tumor and the target volume value. This research investigated volume target delineation for brain tumor against the MRI image of the head in axia...
متن کاملAdvanced quantitative MRI radiomics features for recurrence prediction in glioblastoma multiform patients
Introduction: Advanced quantitative information such as radiomics features derived from magnetic resonance (MR) image may be useful for outcome prediction, prognostic models or response biomarkers in Glioblastoma (GBM). The main aim of this study was to evaluate MRI radiomics features for recurrence prediction in glioblastoma multiform. Materials and Methods:</str...
