Chemotherapy-induced anemia is common in patients who have cancer. Erythropoiesis-stimulating proteins such as epoetin alfa (Procrit) and darbepoetin alfa (Aranesp) have been shown to improve hematologic and clinical outcomes in these patients. Darbepoetin alfa has a longer serum half-life than epoetin alfa, making less frequent administration possible and offering the possibility of synchronizing the administration of erythropoietic therapy and chemotherapy. Several clinical trials have evaluated the utility of darbepoetin alfa given every 3 weeks (q3wk) in patients with chemotherapy-induced anemia. An exploratory study showed that darbepoetin alfa q3wk stabilized hemoglobin levels and reduced transfusion requirements. It was also shown that giving darbepoetin alfa q3wk at the same time as the chemotherapy produced hematopoietic benefits similar to those observed when it is given later in the chemotherapy cycle. The q3wk dosing schedule was effective in patients with mild and moderate anemia, and treatment goals were achieved in most of them. The equivalence of q3wk and qwk darbepoetin alfa has also been established. Synchronous administration of darbepoetin alfa with chemotherapy is a convenient option for patients with chemotherapy-induced anemia, with clinical trials showing it to be an effective treatment strategy.
Ependymoma is a rare central nervous system (CNS) tumor in children, and our progress in treating this disease has been hampered by its rarity as well as by a nonuniform approach to treatment among practitioners. Dr. Merchant’s comprehensive review provides a framework for plotting a course of further progress in treating children with ependymoma.
The Oregon Health Plan was considered by many to be a masterpiece of health care delivery for the poor. It attracted international attention when its plan of explicit rationing of care promised to provide basic health care to virtually every Oregonian living in poverty. Did the plan live up to its promise?
The aim of this review is to summarize the current knowledge on HSCT in CLL and to discuss critically its role in the age of novel treatment strategies.
Breast cancer treatment has evolved greatly within the last 25 years. Tamoxifen was first introduced for the
There are few success stories in solid tumor oncology that match osteogenic sarcoma. Drs. Damron and Pritchard have chronicled this story, and present a multidisciplinary overview of the current management of conventional osteogenic sarcoma.
Conservation of blood is apriority during surgery, owingto shortages of donor bloodand risks associated with transfusionof blood products.[9,10] However,blood transfusions have been linkedto a number of negative postoperativesequelae, including poorer prognosisafter cardiac and cancer surgery.[11-21] In this context, recognition thatallogeneic transfusion-associatedimmunomodulation can increasemorbidity in allogeneically transfusedpatients has become a major concernin transfusion medicine.[9,22,23]
The staging and treatment of prostate cancer are complex, particularly in patients with clinical disease that has advanced locally beyond the confines of the gland. Management choices are made more difficult by a paucity of
In spite of the complicated etiologic, clinical, and pathologic scenario of cryoglobulinemia, physicians can play a key role in its successful management by early recognition of the most common clinical presentations.
The purpose of this paper is to provide an overview of the clinical presentation, diagnosis, and treatment of brain metastases in patients with SCLC, with a focus on current trends and developments in the treatment of this disease.
Pancreatic cancer is the fifth leading cause of cancer death in the United States.In the year 2005, an estimated 32,180 new cases will be diagnosed, and 31,800deaths will be ascribed to this cancer.
With improved prognosis for patients with Hodgkin's lymphoma (HL), interest has increasingly focused on high-risk groups such as elderly patients. Advanced age at presentation is still one of the strongest negative risk factors. Many different factors influence the prognosis in elderly patients. These include biologic differences such as more aggressive histology, different distribution of disease, more frequent diagnosis of advanced stage, and shorter history of disease. In addition, however, aging itself and associated factors such as comorbidity, reduced tolerability of conventional therapy, more severe toxicity and treatment-related deaths, failure to maintain dose intensity, shorter survival after relapse, and death due to other causes contribute to the poorer outcome in elderly patients. Besides the evaluation of specific causes and risk factors, this review highlights recent and ongoing studies for elderly patients with HL as well as international approaches and recommendations for this age group.
Carcinoma of the endometrium is the most common female pelvic malignancy and the fourth most common cancer in females, after breast, bowel, and lung carcinomas. In 1995, an estimated 32,800 new cases of endometrial carcinoma and 5,900 related deaths will occur in the United States [1]. The relatively low mortality for this cancer is probably due to the fact that in 80% of cases, the disease is diagnosed when it is confined to the uterus.
Do not resuscitate (DNR) orders have become an integral part of the care of the terminally ill patient. Often, the decision whether or not to resuscitate a patient in the event of cardiopulmonary arrest must be made by the patient's family members. This is a difficult decision that is made at an emotionally trying time. Our study investigated the satisfaction, understanding, and feelings of families who sign DNR orders for their relatives. We are not aware of any other studies that have evaluated this aspect of the DNR order.
The currently available therapies for colorectal cancer have led to a significant increase in survival, but the majority of patients with advanced disease progress and eventually die of their disease. This is a particularly frustrating scenario when a patient experiences a complete remission, only to recur with refractory disease.
The author of this reference, Dr. John J. Mulvihill, has a long-standing reputation for studying the complexities of human genetic disorders. His experiences, many publications, and collaborations have focused on various topics, including definition of the
Despite advances in surgery, radiotherapy, and chemotherapy, survival of patients with squamous cell carcinoma of the head and neck has not significantly improved over the past 30 years. Locally recurrent or refractory disease is particularly difficult to treat. Repeat surgical resection and/or radiotherapy are often not possible, and long-term results for salvage chemotherapy are poor. Recent advances in gene therapy have been applied to recurrent squamous cell carcinoma of the head and neck. Many of these techniques are now in clinical trials and have shown some efficacy. This article discusses the techniques employed in gene therapy and summarizes the ongoing protocols that are currently being evaluated in clinical trials. [ONCOLOGY 15(3):303-314, 2001]
Here we present the case of a 3-year-old girl with generalized lymphadenopathy and fever, in whom the cause of the symptoms was initially thought to be infectious. Ultimately, however, anaplastic large cell lymphoma (ALCL) was diagnosed. Using this case as a backdrop, we discuss the wide range of systemic illnesses that the differential diagnosis of generalized lymphadenopathy encompasses.
R115777 (Zarnestra) is an orally available methylquinolone derivative from Johnson & Johnson Pharmaceutical Research and Development L.L.C. that is a potent and selective nonpeptidomimetic farnesyltransferase inhibitor (FTI).[1] FTIs represent a new class of agents that were originally developed to inhibit tumors by interfering with posttranslational processing of oncogenic Ras protein. The anticancer activity of FTIs might stem from their ability to effect various proteins other than Ras that can also mediate signal transduction, apoptosis, angiogenesis, and growth.[2]
The patient is a 5-month-old Caucasian boy with no developmental abnormalities who presented Christmas Eve 2004 to his pediatrician with increasing fussiness, emesis, and inability to tolerate oral intake. He had a temperature of 100.2°F but otherwise normal vital signs. Physical exam at that time revealed a distended abdomen. He was sent home with a diagnosis of viral gastroenteritis.
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.
Clinical applications of image-based radiation therapy for the study of prostate cancer have expanded significantly over the past years. The results of recent studies of magnetic resonance imaging (MRI) combined with magnetic
A phase III trial conducted by Eastern Cooperative Oncology Group (ECOG) investigators assessed the possible impact of paclitaxel on survival, response, and toxicity in patients with
As part of our coverage of the ASCO GU Cancers Symposium, we discuss decision-making in the management of patients with early-stage prostate cancer.
An estimated 157,000 patients died of lung cancer in the United States in the year 2000.[1] Although surgery can be curative, only about 20% of patients are amenable to complete surgical resection. Most of the other patients are treated with radiation
Data from the SPOTLIGHT and GLOW trials reveal that zolbetuximab increased survival in patients with CLDN18.2-positive gastric or GEJ adenocarcinoma.
Miriam Friedlander, YanaBrayman, and WilliamBreitbart have produced anexcellent review of delirium in thepalliative care setting. Their paper isthorough, readable, and thoughtful,and will be helpful to oncologists caringfor patients with advanced illness.I particularly like the fact that theauthors make it clear that delirium isnot only a very common complicationof advanced cancer, but that it isalso a major source of suffering anddistress for both patients and families.In view of the problems deliriumpresents and the frequency with whichdelirium arises as death approaches,this complication of advanced and terminalillness has received inadequateattention. My thanks and congratulationsgo to the authors for providingsuch a clear and helpful review of thischallenging clinical problem.
Cytokines have been used in the treatment of patients with cutaneousmelanoma. Granulocyte-macrophage colony-stimulating factor(GM-CSF, sargramostim [Leukine]) leads to dendritic cell/macrophagepriming and activation, and also increases interleukin-2 (IL-2)receptor expression on T lymphocytes. IL-2 creates lymphokineactivatedkiller cells and tumor-infiltrating lymphocyte cells. In thisopen-label, single-arm study of 16 high-risk patients, we combined thesetwo agents to take advantage of their different but complementary functions.All patients underwent potentially curative surgery. Postoperatively,each patient received GM-CSF at 125 μg/m2/d subcutaneously(SC) for 14 days; this was followed by IL-2 at 9 million IU/m2/d SC for4 days, and then 10 to 12 days of no treatment. In addition, patientswho had large tumors that could yield over 100 million live tumor cellsreceived autologous melanoma vaccines. The duration of follow-upranged from 21 to 42 months (median: 27 months). During follow-up,five patients developed metastases. This program was carried out on anoutpatient basis, and no hospitalization was required. It was well toleratedwith minimal side effects. The combination treatment regimen ofGM-CSF and IL-2 with or without autologous vaccine used adjuvantlyappears to benefit high-risk melanoma patients; further clinical testingof this regimen is warranted.
When administered as a single agent in pretreated patients with advanced breast cancer, paclitaxel (Taxol) exhibits remarkable antitumor activity. This trial was undertaken to compare paclitaxel with standard
The 10th edition of Wintrobe’s Clinical Hematology is a two volume, multiauthored work that spans the ever-expanding discipline of hematology in over 2,600 pages. The book is appropriately introduced by an excellent short chapter written previously by Dr. Wintrobe on “The Diagnostic and Therapeutic Approach to Hematologic Problems.” There follows a valuable series of six chapters totaling 133 pages devoted to laboratory hematology, including blood and bone marrow examination, immunodiagnosis, clinical flow cytometry, cytogenetics, clusters of differentiation, and molecular genetics. These chapters contain ample illustrations, diagrams, tables, and references.
