The FDA has approved Merck & Co.'s Emend (aprepitant) for use with other antiemetic medicines for the prevention of nausea and vomiting associated with initial and repeat courses of moderately emetogenic chemotherapy.

ode Gray policies exist at several bureaucratic levels, with Chancellors Memo 51 (CM-51) being the highest policy level. CM-51 states that all LSUHSC personnel, except "approved and emergency personnel," must evacuate LSUHSC when emergency status is declared. Having participated in prior hurricane coverages and debriefings by my department, I performed in a manner consistent with past experience and current policy.

The novel alkylating agent bendamustine appears to induce responses in patients with refractory B-cell non-Hodgkin's lymphoma (NHL), Jonathan W. Friedberg, MD, of the James P. Wilmont Cancer Center, Rochester, New York, said at the 47th Annual Meeting of the American Society of Hematology (abstract 229). The study was sponsored by Cephalon, Inc., which is developing the new agent as Treanda.

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.

As an oncologist, I am always on the lookout for good patient education material. This book, which is based on the experience of the Stanford Integrative Medicine Clinic Cancer Supportive Care Program, is a good choice for a highly literate, print-oriented patient or family member. The book is divided into five parts: (1) Cancer: Diagnosis, Information, and Treatment, (2) The Role of the Mind, (3) The Care of the Body, (4) Supportive and Social Services for Life and Death Issues, (5) Planning for the Future, and (6) Resources. These five parts are divided into 50 individual chapters covering specific topics, and the chapters are focused, concise, and practical.

Last year, I had the opportunity to spend a week at a cancer institute in equatorial Africa. A colleague of mine, Waafa El-Sadr, MD, heads a Columbia University program establishing health-care units in African nations to treat HIV-infected people with antiretro-viral drugs. Waafa was initiating one such unit at the Ocean Road Cancer Institute (ORCI) in Dar el Salaam, Tanzania. When doctors there expressed a need for a visiting oncologist to update them on issues relevant to HIV-infected patients with cancer, Wafaa thought of me. She felt that my experience treating AIDS patients in the days prior to the elaborate regimens we now have would be particularly instructive in the ORCI setting.

With the aging of the Western population, cancer in the older person is becoming increasingly common. After considering the relatively brief history of geriatric oncology, this article explores the causes and clinical implications of the association between cancer and aging. Age is a risk factor for cancer due to the duration of carcinogenesis, the vulnerability of aging tissues to environmental carcinogens, and other bodily changes that favor the development and the growth of cancer. Age may also influence cancer biology: Some tumors become more aggressive (ovarian cancer) and others, more indolent (breast cancer) with aging. Aging implies a reduced life expectancy and limited tolerance to stress. A comprehensive geriatric assessment (CGA) indicates which patients are more likely to benefit from cytotoxic treatment. Some physiologic changes (including reduced glomerular filtration rate, increased susceptibility to myelotoxicity, mucositis, and cardiac and neurotoxicity) are common in persons aged 65 years and older. The administration of chemotherapy to older cancer patients involves adjustment of the dose to renal function, prophylactic use of myelopoietic growth factors, maintenance of hemoglobin levels around 12 g/dL, and proper drug selection. Age is not a contraindication to cancer treatment: With appropriate caution, older individuals may benefit from cytotoxic chemotherapy to the same extent as the youngest patients.

THOUSAND OAKS, California—Amgen and Abgenix, Inc. (Fremont, California) have signed a definitive merger agreement under which Amgen will acquire Abgenix for approximately $2.2 billion in cash plus the assumption of debt. The acquisition of Abgenix provides Amgen with full ownership of one of its most important advanced pipeline products, panitumumab. The agent, which inhibits the epidermal growth factor receptor (EGFR), has shown significant improvement in progression-free survival for metastatic colorectal cancer patients who have failed standard chemotherapy (see ONI December 2005, page 14). Abgenix also brings to the merger its proprietary fully human monoclonal antibody technology, XenoMouse.

Once again, the National Cancer Institute (NCI) faces the likelihood of an annual operating budget lower in actual dollars than the previous year. In the waning days of December 2005, Congress passed the budget for the Department of Health and Human Services (HHS) for fiscal year (FY) 2006, which began October 1, 2005.

Amooranin (AMR), derived from the Amoora rohituka stem bark, shows clinical potential in treating human cancers, Steven Melnick, MD, PhD, said at the Society for Integrative Oncology (SIO) annual meeting (abstract 57). Dr. Melnick, chief, Department of Pathology and Clinical Laboratories, Miami Children's Hospital, said that the Amoora rohituka stem bark is one of the components of a natural preparation used for the treatment of human malignancies in the Ayurvedic system of medicine in India. Derived from stem bark that grows wild in Asia, the preparation contains parts of three medicinal plants: Amoora rohituka stem bark, Glycyrrhiza glabra roots, and Semicarpus anacardium fruits.

For transplant patients with severe acute graft-versus-host disease (GVHD), a novel treatment option may be in the form of another transplant, this time with mesenchymal stem cells (MSCs), according to research presented at the American Society of Hematology annual meeting

Cancer drug regulators at the FDA and the European Medicines Agency (EMEA) have agreed to seven programs aimed at providing each agency with a better understanding of the basis of the scientific advice the other offers, as well as optimizing product development and avoiding unnecessary duplication. The seven initiatives resulted from an agreement finalized on Sept. 16, 2005, between the FDA, EMEA, and the European Commission, the executive body of the European Union.

Accumulating clinical experience with MammoSite breast brachytherapy is supporting its safety, efficacy, and good cosmetic outcomes, while also providing lessons to improve its use, according to a pair of studies presented at the 47th Annual Meeting of the American Society for Therapeutic Radiology and Oncology

The malignant stem cells believed to develop into cells associated with acute myeloid leukemia (AML) appear to be distinguishable from normal stem cells with the use of a novel antigen marker, Gerrit Jan Schuurhuis, PhD, said at the 2005 American Society of Hematology annual meeting (abstract 4). Dr. Schuurhuis is associate professor of hematology, VU University Medical Center, Amsterdam, The Netherlands.

SOUTH SAN FRANCISCO, California—Hana Biosciences has received FDA clearance for its Investigational New Drug Application for Zensana (ondansetron oral spray) to prevent chemotherapy-induced nausea and vomiting. In a press release, Hana said it is initiating a series of pivotal pharmacokinetic trials, including comparison of Zensana with ondansetron tablets (Zofran). Zensana is the first multidose oral spray 5-HT3 antagonist. Patients experiencing nausea and vomiting have difficulty swallowing and holding down pills. Zensana delivers full doses of ondansetron. In addition, drug delivery via a spray to the oral mucosa avoids degradation in the gastrointestinal tract and metabolism by liver enzymes.

The myriad changes that oncology physicians have experienced in the last 20 years are certainly applicable to oncology nurses, in particular, the technology explosion and its effects on diagnosis, treatment, and survivorship; the emergence of cancer as a disease of the elderly; challenges posed by shortages of health care workers; and the fact that almost all cancer patients today are treated as outpatients. Recent therapeutic innovations and management approaches have been keenly felt by oncology nurses, who typically play a major role in patient education.

A 1999 Institute of Medicine (IOM) report, "Ensuring Quality Cancer Care," suggested that many cancer patients in the United States are not receiving the care known to be effective for their disease. The IOM committee recommended a number of remedial steps including the development of a national quality care monitoring system. CC&E spoke with Eric C. Schneider, MD, assistant professor of health policy and management, Harvard School of Public Health, and assistant professor of medicine, Harvard Medical School, about, among other things, the ongoing initiatives to link quality care performance measures to the delivery and reimbursement of oncology services.

On the weekend before Hurricane Katrina struck, Gabriela Ballester, MD, was the hematology/oncology fellow on call for LSU patients at University Hospital (part of the Medical Center of Louisiana at New Orleans, along with Charity Hospital). She shared her story in a telephone interview with ONI.

DENVER-Dose escalation of high dose rate (HDR) brachytherapy may improve long-term survival in men with intermediate- or high-risk prostate cancer, according to findings of a study presented at the 47th Annual Meeting of the American Society for Therapeutic Radiology and Oncology (abstract 63).

Several developments in the past few years have incrementally progressedthe field and provided additional insights into the managementof advanced colorectal cancer. This review discusses the componentsof current cytotoxic chemotherapy regimens for advanced colorectalcancer: fluorouracil (5-FU), capecitabine (Xeloda), irinotecan(Camptosar), and oxaliplatin (Eloxatin). The equivalence of severalfront-line regimens has provided opportunities for increased tailoringof therapies for individual patients. Preliminary data onpharmacogenomics provides hope that we will be able to better matchpatients with regimens and doses on the basis of individualized predictionsof toxicity and response. The importance of second-line therapyin overall survival has again been highlighted; the best outcomes haveoccurred in patients treated with 5-FU, oxaliplatin, and irinotecan incombination with targeted therapies during the course of their disease.Elderly patients are no exception to this finding. Combination regimensand second-line therapy should be offered to elderly patients whohave adequate performance status and no contraindicated comorbidconditions, without regard for their chronological age.

Colorectal cancer is a worldwide public health problem, with nearly 800,000new cases diagnosed each year resulting in approximately 500,000deaths. In the United States, it is the second leading cause of cancer mortality,and nearly 60,000 deaths will be attributed to this disease in 2005. Whendiagnosed as advanced, metastatic disease, colorectal cancer is traditionally associatedwith a poor prognosis, with 5-year survival rates in the range of 5% to 8%. Thissurvival rate has remained unchanged over the past 35 to 40 years. However, duringthe past 5 years, significant advances have been made in treatment options so thatimprovements in 2-year survival are now being reported, with median survival ratesin the 21- to 24-month range in patients with metastatic disease.

WASHINGTON-Older cancer patients who received the colony-stimulating factor (CSF) pegfilgrastim (Neulasta) during each cycle of chemotherapy, including the first, had significantly less febrile neutropenia than patients who received it only after the first cycle, according to the results of a large, community-based clinical trial. Those receiving the drug in the first cycle also had fewer hospitalizations and other neutropenia-related complications, said Lodovico Balducci, MD, head of the senior adult oncology program at H. Lee Moffitt Cancer Center and Research Institute, Tampa, Florida. Dr. Balducci reported the findings at the Geriatric Oncology Consortium annual meeting (abstract 3).

Kauh and colleagues nicely outlinethe major problems facingclinicians who treat humanimmunodeficiency virus (HIV)-positivepatients with squamous cell carcinomaof the anus. This is a highly curabledisease with combined-modality therapy,though the HIV-positive populationpresents unique challenges. Weagree with the approaches outlined bythe authors and would also like to emphasizeseveral principles in the managementof anal cancer.

Squamous cell anal cancer remains an uncommon entity; however,the incidence appears to be increasing in at-risk populations, especiallythose infected with human papillomavirus (HPV) and human immunodeficiencyvirus (HIV). Given the ability to cure this cancer using synchronouschemoradiotherapy, management practices of this disease arecritical. This article considers treatment strategies for HIV-positive patientswith anal cancer, including the impact on chemoradiation-inducedtoxicities and the role of highly active antiretroviral therapy in the treatmentof this patient population. The standard treatment has beenfluorouracil (5-FU) and mitomycin (or cisplatin) as chemotherapy agentsplus radiation. Consideration to modifying the standard treatment regimeis based on the fact that patients with HIV tend to experience greatertoxicity, especially when CD4 counts are below 200; these patients alsorequire longer treatment breaks. Additional changes to the chemotherapydosing, such as giving 5-FU continuously and decreasing mitomycin dose,are evaluated and considered in relation to radiation field sizes in an effortto reduce toxicity, maintain local tumor control, and limit need forcolostomy. The opportunity for decreasing the radiation field size andusing intensity-modulated radiation therapy (IMRT) is also considered,particularly in light of the fact that IMRT provides dose-sparing whilemaximizing target volume dose to involved areas. The impact of the immunesystem in patients with HIV and squamous cell carcinoma of theanus and the associated response to therapy remains unknown. Continuedstudies and phase III trials will be needed to test new treatment strategiesin HIV-infected patients with squamous cell cancer of the anus todetermine which treatment protocols provide the greatest benefits.

The article by Kauh and colleaguesprovides a timely reviewof the therapeutic approachto invasive carcinoma of theanus in human immunodeficiency virus(HIV)-infected patients, which isan emerging clinical problem. Importantlimitations of the published experience,however, need to be pointedout; given the present pursuit of moretargeted anticancer therapy, new avenuesare being explored, even in themanagement of HIV-associated analcancer.

Tremendous gains have been made regarding the treatment of breastcancer. The combination of chemotherapy, radiation therapy, and surgeryhave vastly improved patient course. Hepatic manifestations ofmetastatic breast cancer are extremely difficult to treat. Traditionally,chemotherapy and hormonal treatment of hepatic metastases of breastcarcinoma have not significantly improved survival. For patients withbreast cancer metastases isolated to the liver, operative treatment isincreasingly being used to prolong life and disease-free intervals. Thisarticle reviews the use of surgery for treatment of isolated breast cancermetastases to the liver.

The patient is a 74-year-old gentleman who presented with a visual disturbance and right shoulder pain. On routine chest x-ray, he was found to have a right apical lung mass.

Drs. Winell and Roth provide agood overview of the commonpsychiatric disorders andcancer-related symptoms in elderly individualswith cancer. Because of thelarge and growing percentage of cancerpatients who are over age 65, theauthors duly highlight the importanceof this topic. The article is highly relevantto the clinical practice of oncologyand detailed information is includedto help guide treatment options formajor depression, anxiety, delirium,and other cancer-related symptoms.
