Current Management of Cancer-Associated Anorexia and Weight Loss

In their article in this issue, Drs. Jatoi and Loprinzi review much of the data on weight loss and anorexia in cancer patients from the standpoint of the impact of nutrition and various pharmacologic agents on management, and they make some sound recommendations for therapy. The benefit of nutritional interventions in this area are often overhwhelmed by the patient’s complex disease course and, therefore, are difficult to demonstrate.

The Evolving Approach to Management of Cancer Cachexia

Cancer patients are often referred for cachexia intervention treatments late in their disease trajectory-that is, at a point where attempts to reverse the weight loss process may be less beneficial. In addition, healthcare professionals frequently under-recognize the prevalence of cancer cachexia, and this may contribute to delayed treatment of weight loss, often until the refractory stage.

The Role of Neck Dissection Following Definitive Chemoradiation

The presence of regional nodal metastases represents a significantadverse prognostic factor for patients with squamous cell carcinoma ofthe head and neck. Early-stage head and neck cancers, localized to theprimary site without regional lymph node metastases have excellentcure rates with either surgery or radiation therapy. The presence ofregional metastases results in cure rates that are approximately half ofthose obtainable in early-stage disease. Therefore, due to the significantadverse impact of neck metastases on prognosis, the treatment ofthe neck remains a vital part of the decision-making process in determiningtherapy for head and neck cancer.

New Drugs Bring New Questions

The treatment of metastatic renal cell carcinoma (RCC) has changed dramatically over the past few years. An improved understanding of the biology of RCC has resulted in the development of novel targeted therapeutic agents that have altered the natural history of this disease. In particular, the hypoxia-inducible factor (HIF)/vascular endothelial growth factor (VEGF) pathway and the mammalian target of rapamycin (mTOR) signal transduction pathway have been exploited. Sunitinib malate (Sutent), sorafenib tosylate (Nexavar), bevacizumab (Avastin)/interferon alfa, and temsirolimus (Torisel) have improved clinical outcomes in randomized trials by inhibiting these tumorigenic pathways. Combinations and sequences of these agents are being evaluated. Other novel multitargeted tyrosine kinase inhibitors (pazopanib and axitinib) and mTOR inhibitors (everolimus) are in clinical development. Recently reported and ongoing clinical trials will help further define the role of these agents as therapy for metastatic RCC.

Commentary (Adelstein): The Role of Neck Dissection Following Definitive Chemoradiation

The recent recognition that theaddition of concurrent chemotherapyto definitive radiationcan improve locoregional control, organpreservation, and survival in patientswith squamous cell head andneck cancer has had a significant impacton our management choices.Chemoradiotherapy data from metaanalyses,cooperative group trials, andlarge tertiary care institutions now suggestthat there is a realistic potentialfor cure in almost all patients withlocoregionally confined disease, and thefocus has increasingly shifted towardthe impact of our treatments on longtermfunction. In the past, control ofneck node involvement often requireda comprehensive neck dissection, a procedureassociated with some degree oflong-term morbidity. In this review,Kutler, Patel, and Shah address the importantquestion of whether the neckdissection should be a planned componentin the management of patientstreated with definitive concurrentchemoradiotherapy.

Do Families Understand "Do Not Resuscitate" Orders?

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.

Genome-Wide Association Studies of Cancer: Principles and Potential Utility

Genome-wide association studies (GWAS) have emerged as a new approach for investigating the genetic basis of complex diseases. In oncology, genome-wide studies of nearly all common malignancies have been performed and more than 100 genetic variants associated with increased risks have been identified. GWAS approaches are powerful research tools that are revealing novel pathways important in carcinogenesis and promise to further enhance our understanding of the basis of inherited cancer susceptibility. However, “personal genomic tests” based on cancer GWAS results that are currently being offered by for-profit commercial companies for cancer risk prediction have unproven clinical utility and may risk false conveyance of reassurance or alarm.

Commentary (Hewitt): An Alternative Algorithm for Dosing Transdermal Fentanyl for Cancer-Related Pain

The inadequate treatment of pain associated with malignancy remains a significant clinical problem.[1-4] Despite published guidelines on the appropriate management of cancer pain, 50% of dying patients experience moderate to severe pain.[1,5-8] One of the greatest barriers to the proper treatment of cancer pain remains health care professionals’ lack of knowledge regarding the appropriate use of analgesic medications.[9-11] The failure to refer to and limited availability of knowledgeable specialists in pain and palliative care also contribute to this pervasive problem.[12]

Systemic Therapy for Lung Cancer Brain Metastases: A Rationale for Clinical Trials

Despite the high prevalence of brain metastases in patients with metastatic lung cancer, these patients have been excluded from enrollment in clinical trials of new therapeutic drugs. The reasons for exclusion have centered on concerns that the blood-brain barrier may impede drug delivery into brain metastases, that brain metastases confer a dismal survival for metastatic lung cancer patients, and that brain metastases carry risk for cerebrovascular hemorrhage. A focused, updated review of these issues, however, clearly shows that these particular concerns are unwarranted. An extensive review of clinical trials on the efficacy of chemotheraputic agents against lung cancer brain metastases is also provided. This collective information describes an area in need of therapeutic development and supports an initiative to evaluate novel targeted therapies for lung cancer brain metastases.

Management of Anemia in Patients With Hematologic Malignancies

Anemia is common in patients with hematologic malignancies, and it has negative effects on their quality of life. The current clinical practice guidelines recommend erythropoietic therapy in patients with cancer- or chemotherapy-related anemia, but anemia is often undertreated in patients with hematologic malignancies. Several randomized controlled trials have shown that treatment with erythropoiesis-stimulating proteins such as epoetin alfa (Procrit), epoetin beta, and darbepoetin alfa (Aranesp) increases hemoglobin levels, reduces the need for red blood cell transfusions, and improves quality of life in patients with hematologic malignancies and anemia receiving chemotherapy. Furthermore, preliminary data from a recent open-label study suggest that early treatment of mild anemia in patients with hematologic malignancies treated with chemotherapy produces marked improvements in quality of life and productivity. Increasing patients' hemoglobin levels may also improve their cognitive function. These findings support the use of erythropoietic therapy to manage anemia in patients with hematologic malignancies who are treated with chemotherapy.

Proteomics to Diagnose Human Tumors and Provide Prognostic Information

Proteomics is a rapidly emerging scientific discipline that holds greatpromise in identifying novel diagnostic and prognostic biomarkers forhuman cancer. Technologic improvements have made it possible to profileand compare the protein composition within defined populationsof cells. Laser capture microdissection is a tool for procuring pure populationsof cells from human tissue sections to be used for downstreamproteomic analysis. Two-dimensional polyacrylamide gel electrophoresis(2D-PAGE) has been used traditionally to separate complex mixturesof proteins. Improvements in this technology have greatly enhancedresolution and sensitivity providing a more reproducible and comprehensivesurvey. Image analysis software and robotic instrumentationhave been developed to facilitate comparisons of complex protein expressionpatterns and isolation of differentially expressed proteins spots.Differential in-gel electrophoresis (DIGE) facilitates protein expressionby labeling different populations of proteins with fluorescent dyes.Isotope-coded affinity tagging (ICAT) uses mass spectroscopy for proteinseparation and different isotope tags for distinguishing populationsof proteins. Although in the past proteomics has been primarilyused for discovery, significant efforts are being made to developproteomic technologies into clinical tools. Reverse-phase protein arraysoffer a robust new method of quantitatively assessing expressionlevels and the activation status of a panel of proteins. Surface-enhancedlaser-desorption/ionization time-of-flight (SELDI-TOF) mass spectroscopyrapidly assesses complex protein mixtures in tissue or serum. Combinedwith artificial intelligence–based pattern recognition algorithms,this emerging technology can generate highly accurate diagnostic information.It is likely that mass spectroscopy–based serum proteomicswill evolve into useful clinical tools for the detection and treatment ofhuman cancers.
