OBJECTIVES To investigate the relevance of bevacizumab (BEV)-induced diffusion-restricted lesions and T1-hyperintense lesions in patients with recurrent glioblastoma. METHODS We prospectively screened 74 BEV-treated patients with recurrent glioblastoma for (1) diffusion-restricted lesions and/or, (2) lesions with a hyperintense signal on precontrast T1-weighted images. We further evaluated ov...

Metal baseball bats have been experimentally demonstrated to produce higher ball exit velocity (BEV) than wooden bats. In the United States, all bats are subject to BEV tests using hitting machines that rotate the bat in a horizontal plane. In this paper, a model of bat-ball impact was developed based on 3-D translational and rotational kinematics of a swing performed by high-level players. The...

BACKGROUND Disease assessment for recurrent glioblastoma (GBM) represents a challenge, especially with the use of antiangiogenic agents. Moreover, validated neuroradiological predictors of outcome are lacking. Recently, the concept of early tumor shrinkage (ETS) has been developed to better assess the ability of treatments in determining a rapid and remarkable tumor response. The aim of the stu...

In a previous issue of Critical Care, Jeong et al. reported a beneficial effect of bevacizumab (Bev), the first humanized vascular endothelial growth factor (VEGF)-neutralizing antibody, on vascular permeability and mortality in a murine model of sepsis [1]. VEGF has been associated with mortality during sepsis [2], and the administration of its natural antagonist improved survival in experimen...

Glioblastoma(GBM)is the most malignant and frequent primary brain tumor. The current standard of care consists of maximum safe resection and radiotherapy with concomitant and subsequent temozolomide(TMZ)treatment. With this treatment plan, the prognosis of patients with GBM remains dismal, with a 5-year survival rate of<10%; thus development of effective, novel therapies is needed. Bevacizumab(...

AIM To investigate the efficacy and safety of cape-citabine plus irinotecan +/- bevacizumab in advanced or metastatic colorectal cancer patients. METHODS Forty six patients with previously untreated, locally-advanced or metastatic colorectal cancer (mCRC) were recruited between 2001-2006 in a prospective open-label phase II trial, in German community-based outpatient clinics. Patients receive...

PURPOSE The three-dimensional (3D) dose distribution covering a tumor region tends to be more breakable if the beam's eye view (BEV) of the 3D electron density (ED) map in a beam direction changes more abruptly with large fluctuations. Our aim of this study was to develop an automated determination method of robust beam directions against the patient setup error based on the ED-based BEV in the...

PURPOSE The AVAglio trial established the beneficial effect of add-on bevacizumab (BEV) for the treatment of newly diagnosed glioblastomas (nd-GBMs) that led to the approval of BEV for the treatment of these patients in Japan. However, the rationality of using BEV as a first-line treatment for nd-GBMs remains controversial. The purpose of this study was to analyze the outcomes of a case series ...

Few population-based analyses have investigated survival change in glioblastoma multiforme (GBM) patients treated with concomitant radiotherapy-temozolomide (RT-TMZ) and adjuvant temozolomide (TMZ) and then bevacizumab (BEV) after Food and Drug Administration (FDA) approval, respectively. We aimed to explore the effects on survival with RT-TMZ, adjuvant TMZ and BEV in general GBM population bas...

The aim of the present study was to examine the efficacy of tumor-targeting Salmonella typhimurium A1-R treatment following anti-vascular endothelial growth factor (VEGF) therapy on VEGF-positive human pancreatic cancer. A pancreatic cancer patient-derived orthotopic xenograft (PDOX) that was VEGF-positive and an orthotopic VEGF-positive human pancreatic cancer cell line (MiaPaCa-2-GFP) as well...
