BACKGROUND AND PURPOSE This prospective study sought to determine how the use of combined PET/CT for radiotherapy treatment planning of oesophageal cancer would alter the delineation of tumour volumes compared to CT alone if PET/CT is assumed to more accurately represent true disease extent. PATIENTS AND METHODS All patients underwent FDG-PET/CT scanning(More)
INTRODUCTION The ultra high risk (UHR) for psychosis criteria have been validated in a number of studies. However, it is not known whether particular UHR criteria (Attenuated Psychotic Symptoms (APS), Brief Limited Intermittent Psychotic Symptoms (BLIPS) or Trait vulnerability criteria), or combination of criteria, is associated with a higher risk of(More)
The efficacy and toxicity of carboplatin 100 mg/m2, administered intravenously (IV) daily X 3, and VP-16-213 120 mg/m2, IV daily X 3, administered every 28 days for six courses, was assessed in 94 (36 limited stage, 58 extensive stage) previously untreated patients with small-cell lung cancer. Mediastinal irradiation using 50 Gy in 25 fractions was given to(More)
PURPOSE To report the impact of radiotherapy quality on outcome in a large international phase III trial evaluating radiotherapy with concurrent cisplatin plus tirapazamine for advanced head and neck cancer. PATIENTS AND METHODS The protocol required interventional review of radiotherapy plans by the Quality Assurance Review Center (QARC). All plans and(More)
BACKGROUND Primary diffuse large B-cell lymphoma (DLBCL) of breast is rare. We aimed to define clinical features, prognostic factors, patterns of failure, and treatment outcomes. PATIENTS AND METHODS A retrospective international study of 204 eligible patients presenting to the International Extranodal Lymphoma Study Group-affiliated institutions from(More)
The 20-hour posttransfusion platelet count determines transfusion policy for patients requiring platelet support, and yet factors influencing the 20-hour count have been poorly defined. The clinical factors influencing both the 1- and 20-hour corrected count increment (CCI), were studied in 623 human leukocyte antigen (HLA)-unmatched platelet transfusions(More)
BACKGROUND The curative potential of radiotherapy (RT) alone as initial treatment for patients with Stage I-II lymphocyte-predominant Hodgkin lymphoma (LPHL) has not been defined well. METHODS Two hundred two patients who were treated between 1969 and 1995 were evaluated in a retrospective, multicenter study. RESULTS Patient characteristics were as(More)
To determine the relative importance of clinical factors on the efficacy of platelet transfusions, 941 pooled platelet transfusions from HLA-unmatched donors were studied prospectively in 133 patients with bone marrow failure. Multiple linear regression analyses identified the major factors influencing one-hour-corrected increments (CI) as prior(More)
PURPOSE Promising results in a randomized phase II trial with the hypoxic cytotoxin tirapazamine (TPZ) combined with cisplatin (CIS) and radiation led to this phase III trial. PATIENTS AND METHODS Patients with previously untreated stage III or IV (excluding T1-2N1 and M1) squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx, or larynx were(More)
The pharmacokinetics and pharmacodynamics of prolonged oral etoposide chemotherapy were investigated in 15 women with metastatic breast cancer who received oral etoposide 100 mg as a single daily dose for up to 15 days. There was considerable interpatient variability in the day 1 pharmacokinetic parameters: area under the plasma concentration time curve(More)
