BACKGROUND Brain metastases occur in up to 40% of all patients with systemic cancer. We aimed to assess whether stereotactic radiosurgery provided any therapeutic benefit in a randomised multi-institutional trial directed by the Radiation Therapy Oncology Group (RTOG). METHODS Patients with one to three newly diagnosed brain metastases were randomly(More)
BACKGROUND Concurrent treatment with temozolomide and radiotherapy followed by maintenance temozolomide is the standard of care for patients with newly diagnosed glioblastoma. Bevacizumab, a humanized monoclonal antibody against vascular endothelial growth factor A, is currently approved for recurrent glioblastoma. Whether the addition of bevacizumab would(More)
PURPOSE Salvage options for recurrent high-grade gliomas (HGGs) are limited by cumulative toxicity and limited efficacy despite advances in chemotherapeutic and radiotherapeutic techniques. Previous studies have reported encouraging survival results and favorable toxicity with fractionated stereotactic radiotherapy, and small studies have shown similar(More)
BACKGROUND A phase 3 Radiation Therapy Oncology Group (RTOG) study subset analysis demonstrated improved overall survival (OS) with the addition of stereotactic radiosurgery (SRS) to whole brain radiation therapy (WBRT) in non-small cell lung cancer (NSCLC) patients with 1 to 3 brain metastases. Because temozolomide (TMZ) and erlotinib (ETN) cross the(More)
PURPOSE This study was conducted to determine if prophylactic cranial irradiation (PCI) improves survival in locally advanced non-small-cell lung cancer (LA-NSCLC). PATIENTS AND METHODS Patients with stage III NSCLC without disease progression after treatment with surgery and/or radiation therapy (RT) with or without chemotherapy were eligible.(More)
Publications relating esophageal radiation toxicity to clinical variables and to quantitative dose and dose-volume measures derived from three-dimensional conformal radiotherapy for non-small-cell lung cancer are reviewed. A variety of clinical and dosimetric parameters have been associated with acute and late toxicity. Suggestions for future studies are(More)
BACKGROUND Glioblastoma multiforme (GBM) is the most frequent primary brain tumor in adults. Temozolomide was rapidly incorporated into first-line treatment following the publication of the pivotal European Organization for Research and Treatment of Cancer-National Cancer Institute of Canada phase 3 trial in 2005. However, in the trial, enrollment was(More)
PURPOSE To identify in a multivariate analysis treatment-related factors predisposing patients (pts) with lung cancer to acute esophagitis, expressed as a severity grade or Esophagitis Index (EI). METHODS AND MATERIALS Acute esophagitis is prospectively scored as an RTOG Grade in our institution during and after thoracic radiotherapy. Charts, toxicity(More)
BACKGROUND Stereotactic radiosurgery (SRS) and, more recently, fractionated stereotactic radiotherapy (SRT) have been recognized as noninvasive alternatives to surgery for the treatment of acoustic schwannomas. We review our experience of acoustic tumor treatments at one institution using a gamma knife for SRS and the first commercial world installation of(More)
PURPOSE To determine the effect of dose and fractionation schedule of prophylactic cranial irradiation (PCI) on the incidence of chronic neurotoxicity (CNt) and changes in quality of life for selected patients with limited-disease small-cell lung cancer (LD SCLC). METHODS AND MATERIALS Patients with LD SCLC who achieved a complete response after(More)
