Radioactive Glass Microspheres Effective for HCC Patients
October 1st 2002ORLANDO-Treatment of unre-sectable hepatocellular carcinoma (HCC) with 90-yttrium-embedded glass micro-spheres (TheraSphere, MDS Nordion) appears to be safe, effective, and less toxic than the alternative, transarterial che-moembolization (TACE).
Optimal Use of Antiemetics in the Outpatient Setting
October 1st 2002In his article, Dr. Grunberg charts the history of our understanding of chemotherapy-induced nausea and vomiting, and the discovery and development of drugs for its prevention. He places appropriate emphasis on the serotonin (5-HT3) antagonists-notably, ondansetron, granisetron, and dolasetron-which have revolutionized the field over the past decade.
Brachytherapy in the Treatment of Head and Neck Cancer
October 1st 2002Drs. Quon and Harrison have written an excellent review on the role of brachytherapy in the management of head and neck cancer. Brachytherapy is a time-honored technique, and the authors have carefully reviewed the pertinent literature extolling its virtues. However, there are many papers that fail to document efficacy of brachytherapy over conventional techniques, demonstrating that, similar to surgery, the technique is both patient- and operator-dependent.
Commentary (Coit): Management of Small Bowel Adenocarcinoma
October 1st 2002Malignant small bowel tumors are extremely rare, accounting for 0.1% to 0.3% of all malignancies. Fewer than 2,400 new cases of small bowel malignancy are reported in the United States each year.[1] Malignant tumors, which account for about two-thirds of all primary small bowel tumors, consist of four primary subtypes: adenocarcinoma, carcinoid tumor, lymphoma, and sarcoma (or gastrointestinal [GI] stromal tumor). Each malignancy is characterized by unique predisposing factors, anatomy, and biology. The prevalence, pattern, and relevance of both regional lymph node and distant metastases differ. As a result, the study of malignant small bowel tumors, taken as an aggregate, is fraught with difficulty.
Use of Chemotherapy Supported for Elderly Despite Side Effects
October 1st 2002BOSTON-The elderly may suffer more from the side effects of chemotherapy, but toxicity should not necessarily prevent them from receiving life-saving or palliative treatment, according to two speakers at the 14th international meeting of the Multinational Association for Supportive Care in Cancer (MASCC) and International Association for Oral Oncology.
Better Diet Among Black Men Could Help Reduce Health Disparities
October 1st 2002WASHINGTON-A National Cancer Institute (NCI) summary of the link between diet and health among African-American men shows the impact of their eating habits and how increased consumption of fruits and vegetables can reduce the risk of many diseases, including some cancers.
Tumor-Specific Idiotype Vaccines Promising in B-Cell Lymphomas
September 27th 2002ORLANDO-"Vaccines based on characterized tumor antigens have the advantage of potential tumor specificity from the start," Ronald Levy, MD, chief, Division of Oncology, Stanford University School of Medicine, said at an ASCO satellite symposium on cancer vaccines. Development of such vaccines requires definition and isolation of a specific target, and production of the purified target antigen, he said.
The Molecular Basis of Cancer, 2nd Edition
September 5th 2002Edited by John Mendolsohn, MD, Peter M. Howley, MD, Mark A. Israel, MD, and Lance A. Liotta, MD, PhD, The Molecular Basis of Cancer is designed for students, researchers, and physicians in a variety of disciplines. It does not provide a detailed description of the clinical manifestations of human neoplasia. There is, instead, an extensive presentation of the scientific basis of cancer development and therapy. The book includes the contributions of 61 authors, virtually all of whom are recognized experts in their respective fields, from throughout the United States and Europe. The references are comprehensive and relatively current, given the lag time in going to press. The book will certainly benefit both basic scientists and clinicians alike.
Commonly Used Quality of Life and Symptom Measurement Scales
September 3rd 2002On the following pages are examples of commonly used scales for evaluating quality of life and symptoms associated with anemia in patients with cancer. Please note that some of the scales are copyrighted (and marked as such herein) and may not be reproduced in anyway without the express written consent of the copyright holders.
Iron and the Anemia of Chronic Disease
September 3rd 2002The anemia of chronic disease traditionally is defined as a hypoproliferative anemia of no apparent cause that occurs in association with an inflammatory, infectious, or neoplastic disorder, and resolves when the underlying disorder is corrected. Disordered iron metabolism as manifested by a low serum iron, decreased serum transferrin, decreased transferrin saturation, increased serum ferritin, increased reticuloendothelial iron stores, increased erythrocyte-free protoporphyrin, and reduced iron absorption, is a characteristic feature of the anemia of chronic disease and has been thought to be a major factor contributing to the syndrome.
What Evidence Supports Use of Erythropoietin as a Novel Neurotherapeutic?
September 3rd 2002In its hormonal role, erythropoietin is produced by the kidney in response to hypoxic stress and signals the bone marrow to increase the number of circulating erythrocytes. It has become clear in recent years, however, that erythropoietin and its receptor are members of a cytokine superfamily that mediates diverse functions in nonhematopoietic tissues. Nonhormonal erythropoietin actions include a critical role in the development, maintenance, protection, and repair of the central nervous system (CNS).
Psychological Outcomes Associated With Anemia-Related Fatigue in Cancer Patients
This article examines the relationships between chemotherapy-induced anemia, fatigue, and psychological distress among anemic cancer patients with solid tumors.
Recombinant Human Erythropoietin in Cancer-Related Anemia
September 3rd 2002The clinical development of recombinant human erythropoietin (rHuEPO) has had a remarkable impact on the clinical practice of oncology. A decade ago, randomized, placebo-controlled trials in anemic cancer patients demonstrated that rHuEPO resulted in an improvement in hemoglobin and hematocrit, a reduction in transfusion requirements, and improvement in quality-of-life (QOL) end points. Based on these trials, recombinant erythropoietin was approved for the treatment of anemia in patients with nonmyeloid malignancies in whom the anemia was caused by the effect of chemotherapy.
When Is it Justified to Treat Symptoms? Measuring Symptom Burden
September 3rd 2002Symptom burden is certainly not a new concept in the literature on disease and treatment, but recent developments in our understanding of how to measure symptoms and their impact make it possible to cast symptom burden as a reasonable summary measure of both disease- and treatment-outcome status. We discuss the use of symptom burden as an alternative to quality-of-life measures or as a supplement to these measures.
Overcoming Barriers to Erythropoietic Therapy
September 3rd 2002Barriers to use of erythropoietic therapy in cancer patients include nonresponse in a sizable proportion, resultant lowering of cost-effectiveness, and inconvenience. Darbepoetin alfa represents the outcome of efforts to develop agents with improved erythropoietic potency.
The Potential for Anemia Treatment to Improve Survival in Cancer Patients
September 3rd 2002One of the most fundamental challenges to multicellular life is the delivery of sufficient oxygen and metabolic substrate to all cells and the rapid elimination of acid formed during cellular respiration. Thus it is logical to wonder whether anemia, by compromising these pathways, might contribute to the progression of cancer.
Anemia in Cancer Patients: Significance, Epidemiology, and Current Therapy
September 3rd 2002Anemia in cancer patients is associated with a decline in energy levels, activity levels, and quality of life, and these variables improve when hemoglobin levels rise. Importantly, the impact of improved hemoglobin levels on response to chemotherapy, radiation therapy, and survival time is under study.
Erythropoietic Agents as Neurotherapeutic Agents: What Barriers Exist?
September 3rd 2002Erythropoietin is the primary physiological regulator of erythropoiesis, and it exerts its effect by binding to cell surface receptors. It has recently been shown that both erythropoietin and its receptor are found in the human cerebral cortex, and that, in vitro, the cytokine is synthesized by astrocytes and neurons, has neuroprotective activity, and is up-regulated following hypoxic stimuli. In animal models, exogenous recombinant human erythropoietin has been reported to be beneficial in treating experimental global and focal cerebral ischemia and reducing nervous system inflammation
Assessing Quality of Life in Research and Clinical Practice
September 3rd 2002There is a growing recognition in oncology of the importance of maintaining or improving patients’ quality of life (QOL) throughout the disease course. With this goal in mind, many clinical trials in oncology now seek to evaluate QOL end points.
Practitioners’ Practical Model for Managing Cancer-Related Anemia
September 3rd 2002Anemia is the most common hematologic abnormality seen in patients with cancer. Anemia is associated with debilitating symptoms and poorer health-related quality of life and may result in less than optimal disease/treatment outcomes.
Childhood Survivors May Not Know Their Past Rx
September 1st 2002NIAGARA-ON-THE-LAKE, Ontario, Canada-"Adequate knowledge of a cancer diagnosis and treatment is necessary in order to offer appropriate follow-up to cancer survivors," Nina Kadan-Lottick, MD, said at the 7th International Conference for Long-Term Complications of Treatment of Children and Adolescents for Cancer (abstract 22), hosted by Roswell Park Cancer Institute.
Physician Experience Predicts HIV-Related Mortality
September 1st 2002SEATTLE-The number of HIV-infected patients that a physician has treated independently predicts HIV-related mortality in patients starting anti-retroviral therapy for the first time, Robert S. Hogg, PhD, said at the 9th Conference on Retroviruses and Opportunistic Infections (abstract 749W).
Comprehensive Geriatric Evaluations Improve Care
September 1st 2002BOSTON-Elderly cancer patients who are very healthy can usually tolerate cancer treatments. Most elderly patients have comorbidities, however, and oncologists are being urged to conduct a comprehensive geriatric evaluation before deciding on a course of treatment.
