Anemia is a widely prevalent complication among cancer patients. At the time of diagnosis, 30% to 40% of patients with non-Hodgkin lymphoma or Hodgkin lymphoma and up to 70% of patients with multiple myeloma are anemic; rates are higher among persons with myelodysplastic syndromes. Among patients with solid cancers or lymphomas, up to half develop anemia following chemotherapy. For almost 2 decades, erythropoiesis-stimulating agents (ESAs) were the primary treatment for cancer-related anemia. However, reassessments of benefits and risks of ESAs for cancer-associated anemia have occurred internationally. We reviewed guidelines and notifications from regulatory agencies and manufacturers, reimbursement policies, and utilization for ESAs in the cancer and chronic kidney disease settings within the United States, Europe, and Canada. In 2008 the US Food and Drug Administration (FDA) restricted ESAs from cancer patients seeking cure. Reimbursement is limited to hemoglobin levels < 10 g/dL. In the United States, ESA usage increased 340% between 2001 and 2006, and decreased 60% since 2007. The European Medicines Agency (EMEA) recommended that ESA benefits do not outweigh risks. In Europe between 2001 and 2006, ESA use increased 51%; since 2006, use decreased by 10%. In 2009, Canadian manufacturers recommended usage based on patient preferences. In Canada in 2007, approximately 20% of anemic cancer patients received ESAs, a 20% increase since 2004. In contrast to Europe, where ESA use has increased over time, reassessments of ESA-associated safety concerns in the United States have resulted in marked decrements in ESA use among cancer patients.

Annually, adverse drug reactions (ADRs) result in costs of $3.6 billion and 140,000 deaths.1 Yet in 2005, only 15,107 reports of fatalities linked to potential drug toxicity were reported to the US Food and Drug Administration.2 This low number suggests that, despite significant morbidity and morality, ADRs remain underappreciated by clinicians. This is particularly troublesome when it comes to ADRs associated with oncology drugs.

The increased approval of anticancer agents has led to unprecedented results, with improved quality of life and longer survival times, resulting in millions of individuals living with a diagnosis of cancer. Whereas these novel medical, surgical, and radiation regimens, or combinations thereof, are largely responsible for these remarkable achievements, a new, unexpected constellation of side effects has emerged. Most notably, cutaneous toxicities have gained considerable attention, due to their high frequency and visibility, the relative effectiveness of anti–skin toxicity interventions, and the otherwise decreasing incidence of systemic or hematopoietic adverse events. Optimal care dictates that dermatologic toxicities must be addressed in a timely and effective fashion, in order to minimize associated physical and psychosocial discomfort, and to ensure consistent antineoplastic therapy. Notwithstanding the critical importance of treatment-related toxicities, dermatologic conditions may also precede, coincide, or follow the diagnosis of cancer. This review provides a basis for the understanding of dermatologic events in the oncology setting, in order to promote attentive care to cutaneous health in cancer patients and survivors.

On June 29, 2005, President Bush signed into law the Patient Navigator Outreach and Chronic Disease Prevention Act of 2005 (H.R. 1812). This legislation authorized the National Cancer Institute (NCI) to oversee the distribution of $25 million in competitive 5-year grants to help underserved communities access health care services.

In the wake of the Hurricane Katrina crisis, untold numbers of medical records may have been lost. Many evacuees forgot or misplaced their medications, and some do not remember the names of all their medications. With no access to previous medical records, the evacuees’ doctors have no way of confirming medications, immunizations, test results, and other past history. The storm has led to increased demands for electronic hospital records.

In their article, Drs. Matthew Cooperberg,Sangtae Park, and PeterCarroll summarize four nationalregistries that have studied risk migration,practice patterns, outcomepredictions, and quality-of-life outcomesin prostate cancer. Each of thesefour large registries-the Prostate CancerOutcomes Study (PCOS), the Departmentof Defense Center for ProstateDisease Research (CPDR), the Cancerof the Prostate Strategic Urologic ResearchEndeavor (CaPSURE), and theShared Equal Access Regional CancerHospital (SEARCH)-has a particularstrength that complements theothers. As more patients enroll in theseregistries, researchers will gain greaterinsight into the patterns of care andclinical and health-related quality oflife for diverse cohorts of prostate cancerpatients.

The Northwestern University Costs of Cancer Program consists ofa series of pilot studies that address the costs of cancer care. Theprogram is designed to serve as a template in preparation for undertakinga large-scale study of a nationally representative sample of cancerpatients-ie, in preparation for a cancer costs and services utilizationstudy in the future. In this article, we outline the theoretical frameworkassociated with a study of cancer costs and summarize findings fromour ongoing pilot studies in this area.

During the HIV epidemic in the 1980s, more than half of the hemophiliac patients living in many countries, including the United States, France, Denmark, and Japan, became infected with HIV as a result of blood transfusions with contaminated blood or blood products.[1,2] Since the clotting factor needed to treat hemophiliacs was manufactured by pooling plasma from thousands of donors, even one HIV-infected donor could contaminate the entire supply, infecting hundreds.

With no clearly superior treatment for localized prostate cancer, physicians and patients would like to increase patient participation in the decision-making process. Unfortunately, physicians frequently have difficulty understanding patients’ preferences, and patients often do not have sufficient knowledge to make an informed treatment decision. Shared- decision-making tools, such as decision analyses, may increase patient participation and thereby improve physicians’ understanding of their patients’ views.

In this article (the first of a two-part interview), Benjamin Djulbegovic, MD, PhD, discusses the uncertainty principle in clinical trials, a subject he has written about in The Lancet and elsewhere. Dr. Djulbegovic is associate professor of medicine, Divisions of Blood and Marrow Transplantation, H. Lee Moffitt Cancer Center and Research Institute at the University of South Florida, Tampa.

CHICAGO-The Institute of Medicine (IOM) defines health care access as "timely use of affordable, continuous, quality health services which are sensitive to individual needs in order to achieve the best possible health outcomes," Jeanne Mandelblatt, MD, MPH, PhD, said at the Robert H. Lurie Comprehensive Cancer Center of Northwestern University’s annual Health Policy Symposium.

This article is the last in a series focusing on ethical issues in cancer care, prepared by researchers at Northwestern University. The articles highlight selected ethical issues, place the issues in the context of relevant literature, and comment on their significance in oncology practice. These issues are discussed in greater depth in Ethical Issues in Cancer Care (Kluwer, 1999).

Technological ad-vances in cancer prevention and therapy have dramatically reduced cancer mortality, yet literacy continues to be a formidable obstacle to the treatment and prevention of cancer. Patients with low literacy skills who are unable to read and comprehend medical information vital to their health cannot take advantage of these innovative early detection programs and treatments.

The Second Annual Robert H. Lurie Comprehensive Cancer Center Health Policy Symposium, held last year in Chicago, was entitled “Cancer, Reaching Medically Underserved Populations: Low Literacy and Culturally Specific Barriers.”This is the fourth in a series of reports on the conference presentations, prepared for ONI by researchers at Northwestern Medical School, that will put the discussions into a broader context. This month’s article reviews a presentation by Chanita Hughes, PhD, Georgetown University Medical Center, Lombardi Cancer Center, Washington, DC.
