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.

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.
Nordion’s Monte Carlo Dose Calculation Software Approved
September 1st 2002OTTAWA, Canada-MDS Nordion has received 510(k) approval from the US Food and Drug Administration, as well as from Health Canada, for its Monte Carlo electron radiotherapy treatment calculation technique. Developed in collaboration with scientists at the National Research Council Canada, the software provides greater accuracy in calculating the dose required for cancer patients receiving radiation therapy, the company said in a news release.
Imatinib Inactive in Sarcomas That Lack C-KIT/PDGF
September 1st 2002ORLANDO-The tyrosine inhibitor imatinib mesylate (Gleevec) is active in gastrointestinal stromal tumors (GISTs) but not in other soft-tissue sarcomas not characterized by C-KIT or PDGF-R expression, the targets of imatinib, Ian R. Judson, MD, said at the American Society of Clinical Oncology annual meeting (abstract 1609).
Task Force Recommends Screening for All Age 50 and Over
September 1st 2002ROCKVILLE, Maryland-Every man and woman age 50 or older with an average risk of colorectal cancer should be screened for colorectal cancer periodically, according to a new and strong recommendation from the US Preventive Services Task Force (USPSTF). The panel’s report also said screening for the disease at an earlier age in people at high risk is a reasonable practice.
NIH, Drug Industry Target Barriers to Patient Accrual in Clinical Trials
September 1st 2002BETHESDA, Maryland-A new partnership between the National Institutes of Health and five major drug companies will provide a total of $6 million to several cancer centers to find ways to increase accrual to early clinical trials. The five pharmaceutical firms involved in the pilot program are Aventis, Bristol-Myers Squibb, Eli Lilly and Co., GlaxoSmithKline, and Novartis.
Cranial Radiotherapy for Childhood ALL Linked to Adult Obesity
September 1st 2002NIAGARA-ON-THE-LAKE, Ontario, Canada-Treatment for acute lymphoblastic leukemia (ALL) as a child may increase the risk for obesity in adulthood, and a new study suggests that cranial irradiation may be a factor. The results (abstract 13) were presented at the 7th International Conference for Long-Term Complications of Treatment of Children and Adolescents for Cancer, hosted by Roswell Park Cancer Institute.
Drug Resistance Rising Among Newly Infected
September 1st 2002SAN DIEGO, California-The prevalence of drug resistance in men newly infected with HIV is increasing, and such patients are more likely to fail initial antiretroviral therapy, according to a study of 202 subjects from 10 North American cities.
Adult Cigarette Smoking Declined Between 1993 and 2000: CDC Report
September 1st 2002WASHINGTON- The Centers for Disease Control and Prevention (CDC) reported a modest but statistically significant decrease in the number of US cigarette smokers. The new analysis involved self-reported data generated by the 2000 National Interview Survey sample adult core questionnaire and cancer control module. The report found that about 23.3% of adults are current smokers vs 25.0% in 1993. Seventy percent of adult smokers said they wanted to quit, and 41% had tried to quite at least once.
Alemtuzumab/Rituximab Feasible, Active in Lymphoid Malignancies
September 1st 2002LUGANO, Switzerland-Combination monoclonal antibody treatment of lymphoid malignancies may be as safe as single-antibody therapy, and produces a better overall response rate, new data suggest. The data come from a recent study of 48 heavily pretreated, poor-prognosis patients treated with the combination of alemtuzumab (Campath-1H) and rituximab (Rituxan), presented at the 8th International Conference on Malignant Lymphoma (ICML).
Hyperthermia Boosts Chemo Effect in Large Breast Cancers
September 1st 2002ORLANDO-A neoadjuvant treatment approach that involves the administration of liposomal doxorubicin (Myocet, investigational in the United States) and paclitaxel (Taxol), then heat delivery to the tumor, appears to enhance the efficacy of the chemotherapy, according to a study reported at the 38th Annual Meeting of the American Society of Clinical Oncology (abstract 200). Lead investigator Kimberly Blackwell, MD, a medical oncologist at Duke University Comprehensive Cancer Center, called the results "impressive."
