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.

Zoledronic Acid Effective as Treatment for Bone Complications in Prostate Cancer Patients
September 1st 2002The bisphosphonate zoledronic acid (Zometa) is effective in the treatment of skeletal-related events from bone metastases in prostate cancer patients, according to data presented at the 97th annual meeting of the American Urological Association. Patients with advanced prostate cancer are at high risk for bone complications, including bone pain, pathologic fractures, need for radiation or surgery to bone, and spinal cord compression. This study marks the first time a bisphosphonate has demonstrated efficacy in the treatment of bone metastases in this patient population.
Role of Octreotide in Cancer and Therapy-Related Complications
September 1st 2002Octreotide (Sandostatin), a somatostatin analog, has a wide range of uses in the management of cancer patients. It is a unique molecule that specifically binds to somatostatin receptor subtype 2. This property of activating the receptor can result in a multitude of physiologic actions (for example, inhibition of synthesis and release of peptides in endocrine and neoplastic cells, antiangiogenesis, antisecretory effect in the gastrointestinal mucosa, anticholecystokinin activity retarding gallbladder motility, and reduction in splanchnic blood flow). In addition, in vitro experiments confirm that octreotide has cytostatic activity against a variety of malignancies. Octreotide is now widely used in the treatment of hormonal syndromes that result from a variety of neuroendocrine and endocrine neoplasms. Its dramatic effect in controlling malignant carcinoid syndrome and hormone-induced diarrhea (for example, from gastrinoma and VIPoma) has been well documented. However, the chronic use of octreotide can result in steatorrhea and gallstone formation.
Alimta for Mesothelioma to Be Available on Expanded Access Basis
September 1st 2002INDIANAPOLIS-Based on phase III trial results presented at ASCO (see ONI, July 2002, page 1), Eli Lilly and Company and the US Food and Drug Administration have reached an agreement to make Alimta (pemetrexed) available on an expanded access, or compassionate use, basis to medically eligible patients with malignant pleural mesothelioma. Lilly is pursuing approval of Alimta in combination with cisplatin (Platinol) for this indication. For more information, physicians may call 1-866-347-9503.
Medical Management of Carcinoid Neoplasms: Present and Future Considerations
September 1st 2002Much progress in the diagnosis and management of well-differentiated neuroendocrine malignancies is evident over the past 2 decades. Initial medical intervention using somatostatin analogs such as octreotide acetate in the immediate and sustained release formulations (Sandostatin and Sandostatin LAR Depot) is standard for the symptomatic stage IV patient.[1,2] Somatostatin analogs provide effective hormonal suppression for carcinoid neoplasm, pancreatic islet cell malignancies, and pituitary adenomas.
