PURPOSE The lack of accurate criteria to predict the response to radiotherapy for individual patients with squamous cell carcinoma of the head and neck (HN-SCC) remains a major problem. The purpose of this study was to investigate the role of several biologic tumor markers to complement clinical prognostic factors in the assessment of response to(More)
We conducted a randomized, controlled trial comparing thalidomide-prednisone as maintenance therapy with observation in 332 patients who had undergone autologous stem cell transplantation with melphalan 200 mg/m2. The primary end point was overall survival (OS); secondary end points were myeloma-specific progression-free survival,progression-free survival,(More)
Graft-versus-host disease in the upper gastrointestinal tract presents with anorexia, vomiting, and abdominal discomfort. Because these symptoms are not specific, we have proposed that a diagnosis of upper GI GVHD requires histologic confirmation. However, the utility of upper endoscopy in the diagnosis of upper GI GVHD has not been examined. We report a(More)
PURPOSE Many cancer patients take antioxidant vitamin supplements with the hope of improving the outcome of conventional therapies and of reducing the adverse effects of these treatments. A randomized trial was conducted to determine whether supplementation with antioxidant vitamins could reduce the occurrence and severity of acute adverse effects of(More)
The response to therapy of acute graft-versus-host disease (GVHD) is uncertain in recipients of unrelated donor (URD) bone marrow transplant (BMT). We analysed the outcome of treatment in 42 patients with moderate/severe acute GVHD. Initial therapy consisted of prednisone 60 mg/m2 orally daily for 7 days (n = 42), followed by anti-thymocyte globulin (ATG)(More)
BACKGROUND Pretreatment with anti-thymocyte globulin (ATG) decreases the occurrence of chronic graft-versus-host disease (CGVHD) after haemopoietic cell transplantation from an unrelated donor, but evidence of patient benefit is absent. We did a study to test whether ATG provides patient benefit, particularly in reducing the need for long-term(More)

Uncertainty makes the analysis of even simple situations difficult. It forces situation analysts to formulate and manage hypotheses during the construction of the explicit representations of the real world situations. Because of human cognitive limitations, this may quickly become overwhelming, even for the most experienced and capable analysts. In an(More)
