Predictors of survival for patients with cancer after cryptogenic stroke
Abstract Patients with active cancer experience ischemic stroke via cryptogenic mechanisms, with cancer-associated hypercoagulability being considered a major contributor to such strokes. Despite the remarkably shortened survival of these patients, the clinical predictors of survival are poorly understood. We determined the clinical factors including D-dimer levels serving as the predictors of overall survival in these patients. Retrospective study was conducted on cancer patients who visited our hospital for acute ischemic stroke with cryptogenic mechanisms from April 2012 through November 2014. Demographics, cl...

Ischemic stroke in patients with gliomas at The University of Texas-M.D. Anderson Cancer Center
Abstract Patients with gliomas are at risk of cerebrovascular accidents (CVA) with potential consequences on survival, function, and local tumor control. Our objective was to provide information about CVA in patients with gliomas and to estimate survival in this group. We reviewed all adult glioma patients with ischemic CVA at the University of Texas-M.D. Anderson Cancer Center from 2003 through 2014. We extracted demographic, clinical, imaging, treatment and outcome data. We used descriptive summary data and estimated or compared survival rates where appropriate. 60 of 6500 patients (0.1 %) with high-grade (HGG,...

Calcification in high grade gliomas treated with bevacizumab
Abstract Calcification is a rare phenomenon in high grade glioma (HGG). CT scans are sensitive to mineralization but used infrequently for tumor assessment in the MRI era. The presence of calcification can be overlooked on routine MRI. Calcification may reflect chronicity and natural changes in the tumor or its milieu over time and may be accelerated by certain treatments. Calcification may have clinical significance which could signal potential risk for stroke or hemorrhage related to particular therapies; or it may be a positive prognostic factor for treatment response. The true incidence and relevance of calcif...

Diagnostic yield of echocardiography in cancer patients with ischemic stroke
Abstract The yield of echocardiography in cancer patients with acute ischemic stroke is unknown. We identified adult patients with active systemic cancer diagnosed with acute ischemic stroke at a tertiary-care cancer center from 2005 through 2009 who underwent transthoracic (TTE) or transesophageal echocardiography (TEE). Two neurologists independently reviewed all clinical data, including TTE and TEE reports, and adjudicated whether echocardiographic studies revealed a definite or possible source of stroke according to pre-defined criteria. Patients were classified as having suspected cardioembolic strokes if ima...

Phase II trial of hypofractionated intensity-modulated radiation therapy combined with temozolomide and bevacizumab for patients with newly diagnosed glioblastoma
This study demonstrated 90 % 6-month PFS and OS comparable to historic data in patients receiving standard treatment. Bevacizumab did not prevent radiation necrosis associated with this hypofractionated radiation regimen and large PTV volumes may have contributed to high rates of presumed radiation necrosis.

Risk factors for venous thromboembolism in patients undergoing craniotomy for neoplastic disease
Abstract Patients undergoing neurosurgical procedures for neoplasia have historically been considered at higher risk for developing venous thromboembolism (VTE). We sought to identify risk factors associated with VTE in patients undergoing craniotomy for tumor resection. We reviewed a national surgical quality database (American College of Surgeons National Surgical Quality Improvement Project, ACS-NSQIP, http://site.acsnsqip.org/). Patients undergoing non-emergent craniotomy for neoplastic indications were identified based on current procedural terminology codes. Clinical factors were identified that were associ...
