Perioperative Immunosuppressive Factors during Cancer Surgery: An Updated Review. Cancers (Basel) 2024; 16:2304.

Abstract
Surgical excision of the primary tumor represents the most frequent and curative procedure for solid malignancies. Compelling evidence suggests that, despite its beneficial effects, surgery may impair immunosurveillance by triggering an immunosuppressive inflammatory stress response and favor recurrence by stimulating minimal residual disease. In addition, many factors interfere with the immune effectors before and after cancer procedures, such as malnutrition, anemia, or subsequent transfusion. Thus, the perioperative period plays a key role in determining oncological outcomes and represents a short phase to circumvent anesthetic and surgical deleterious factors by supporting the immune system through the use of synergistic pharmacological and non-pharmacological approaches. In line with this, accumulating studies indicate that anesthetic agents could drive both protumor or antitumor signaling pathways during or after cancer surgery. While preclinical investigations focusing on anesthetics' impact on the behavior of cancer cells are quite convincing, limited clinical trials studying the consequences on survival and recurrences remain inconclusive. Herein, we highlight the main factors occurring during the perioperative period of cancer surgery and their potential impact on immunomodulation and cancer progression. We also discuss patient management prior to and during surgery, taking into consideration the latest advances in the literature.

Abstract
Erythropoiesis-stimulating agents (ESAs) epoetin alfa (EA) and darbepoetin alfa (DA) increase hemoglobin (Hb) levels and reduce red blood cell (RBC) transfusion requirements in patients with cancer chemotherapy-associated anemia (CAA). Extended-interval ESA dosing (administration less than once weekly) is common with DA, but previous studies suggested that EA might also be administered less often than weekly. In this multicenter prospective trial, 239 CAA patients with Hb <10.5 g/dL were randomized to receive EA 40,000 U subcutaneously once weekly ("40K" arm), EA 80,000 U every 3 weeks ("80K"), EA 120,000 U every 3 weeks ("120K" arm), or DA 500 mcg every 3 weeks ("DA"), for 15 weeks. The primary endpoint was the proportion of patients achieving Hb ≥ 11.5 g/dL or increment of Hb > 2.0 g/dL from baseline without transfusion. Secondary endpoints included transfusion requirements, adverse events (AEs), and patient-reported outcomes (PROs). There were no significant differences between treatment arms in the proportion of patients achieving Hb response (68.9% for 40K, 61.7% for 80K, 65.5% for 120K, and 66.7% for DA; P > 0.41 for all comparisons) or requiring RBC transfusion, but the median Hb increment from baseline was higher in the 40K and DA arms compared to the two extended dosing EA arms, and Hb response was achieved soonest in the weekly EA arm. There were no differences in PROs or AEs. The FDA-approved schedules tested-weekly EA 40,000 U, and every 3 week DA 500 mcg-are reasonable standards for CAA therapy.

Abstract
A bidirectional relationship has been observed for kidney disease and cancer. On the one hand, cancer is an important complication noted in kidney disease as well as a major cause of morbidity and mortality in this group. On the other hand, improved cancer treatment has prolonged survival, but also increased the development of acute and chronic kidney disease. The combination of cancer and kidney disease makes it challenging for clinicians to provide comprehensive and safe therapies for this group of patients. As such, clinicians caring for this group must develop expertise and become competent in the practice of a newly evolving subspecialty of nephrology known as 'onco-nephrology'. This brief narrative review will focus on the cancer risk in patients with underlying kidney disease, the therapies such as erythropoiesis-stimulating agents on cancer progression and other outcomes, and the appropriate dosing of anti-cancer agents in patients with underlying kidney disease.

Abstract
BACKGROUND WSG-ARA plus trial evaluated the effect of adjuvant darbepoetin alfa (DA) on outcome in node positive primary breast cancer (BC). PATIENTS AND METHODS One thousand two hundred thirty-four patients were randomized to chemotherapy either with DA (DA+; n = 615) or without DA (DA-; n = 619). DA (500 µg q3w) was started at hemoglobin (Hb) levels <13.0 g/dl (<12 g/dl after DA label amendment) and stopped at Hb levels ≥14.0 g/dl (12 g/dl after label amendment). Primary efficacy end point was event-free survival (EFS); secondary end points were toxicity, quality of life (QoL) and overall survival (OS). RESULTS Venous thrombosis (DA+: 3.0%, DA-: 1.0%; P = 0.013) was significantly higher for DA+, but not pulmonary embolism (0.3% in both arms). Median Hb levels were stable in DA+ (12.6 g/dl) and decreased in DA- (11.7 g/dl). Hb levels >15 g/dl were reported in 0.8% of cycles. QoL parameters did not significantly differ between arms. At 39 months, DA had no significant impact on EFS (DA+: 89.3%, DA-: 87.5%; Plog-rank = 0.55) or OS (DA+: 95.5%, DA-: 95.4%; Plog-rank = 0.77). CONCLUSIONS DA treatment did not impact EFS or OS in routine adjuvant BC treatment.

Exp Neurol 2011; 232:126-35. [PMID: 21872588 PMCID: PMC3202026 DOI: 10.1016/j.expneurol.2011.05.025] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2011] [Revised: 04/28/2011] [Accepted: 05/26/2011] [Indexed: 01/23/2023]
Abstract
The Akita mouse is a robust model of diabetic autonomic neuropathy which develops severe diabetes following beta cell death, which occurs reproducibly at 3-4 weeks of age, and maintains the diabetic state without therapy for as long as 11 additional months. Neuritic dystrophy and neuronopathy involving prevertebral sympathetic superior mesenteric and celiac ganglia begin to develop within the first two months of onset of diabetes and are progressive with time. We have examined the effect of insulin implants resulting in normoglycemia and injections of ARA290, a small erythropoietin peptide which has no effect on glycemic parameters, on the reversal of established neuritic dystrophy and neuronopathy. We have found that 4 weeks of insulin therapy beginning at 2 months of diabetes resulted in normalization of blood glucose, body weight and HbA1c. Insulin therapy successfully reversed established neuritic dystrophy and neuronopathy to control levels. Numbers of sympathetic neurons were not significantly changed in either 3 month diabetic or insulin-treated Akita mice. Treatment with ARA290 for 7 weeks beginning at 4 months of diabetes did not result in altered metabolic severity of diabetes as measured by blood glucose, body weight or HbA1c levels. ARA290 treatment was able to decrease neuritic dystrophy by 55-74% compared to untreated diabetics or in comparison to a separate group of diabetic animals representing the 4 month treatment onset point. Surprisingly, there was no effect of ARA290 on ganglionic neuron number or ongoing neuronopathy (pale/degenerating neurons) in diabetic Akita mice during this time period. The development of neuroprotective EPO-like peptides may provide a possible future therapy for this debilitating complication of diabetes; however, it appears that discrete elements may be differentially targeted by the diabetic state and may require selective therapy.

Abstract
The glycoprotein hormone erythropoietin (EPO) is a key regulator in the production of red blood cells. EPO is produced mainly in the embryonic liver and kidney of adults. Other organs are also known to express varying amounts of EPO. In our study, we have analyzed the epigenetic regulation of EPO in human cancer cell lines by DNA methylation assays, chromatin immunoprecipitation, RT-PCR, and promoter analysis under different growth conditions. Moreover, the growth-related effects of ectopic EPO expression were analyzed in a head and neck cancer cell line. We found frequent DNA hypermethylation of the CpG island promoter and enhancer of EPO in different cancer cell lines. Aberrant methylation of EPO promoter was observed in primary lung, head and neck, breast, and liver cancers. Hypermethylation of EPO was associated with a decreased expression of EPO in cancer cells. Treatment of cancer cell lines with 5-aza-2'-deoxycytidine (Aza), an inhibitor of DNA methylation, reactivated EPO expression under hypoxia. In contrast, in the liver cancer cell line HepB3, the EPO promoter was unmethylated, and a high EPO expression was observed independently of Aza treatment. Moreover, in vitro hypermethylation of the EPO promoter and enhancer reduced expression of a reporter gene under normoxia and hypoxia. Induction of EPO under hypoxia was accompanied by increased histone H3 acetylation and reduced histone H3 lysine 9 trimethylation. In a head and neck cancer cell line, which exhibited low EPO levels, ectopic expression of EPO significantly enhanced proliferation under normoxia and hypoxia. In summary, we show that hypermethylation of regulatory sequences of EPO is frequently observed in tumors and that this aberrant methylation induces epigenetic silencing of EPO in cancer cells.

Abstract
Erythropoietin (EPO), the main hemopoietic hormone synthesized by the kidney as well as by the liver in fetal life, is implicated in mammalian erythropoiesis. Production and secretion of EPO and the expression of its receptor (EPO-R) are regulated by tissue oxygenation. EPO and EPO-R, expressed in several tissues, exert pleiotropic activities and have different effects on nonhemopoietic cells. EPO is a cytokine with antiapoptotic activity and plays a potential neuroprotective and cardioprotective role against ischemia. EPO is also involved in angiogenesis, neurogenesis, and the immune response. EPO can prevent metabolic alterations, neuronal and vascular degeneration, and inflammatory cell activation. Consequently, EPO may be of therapeutic use for a variety of disorders. Many tumors express EPO and/or EPO-R, but the action of EPO on tumor cells remains controversial. It has been suggested that EPO promotes the proliferation and survival of cancer cells expressing EPO-R. On the other hand, other reports have concluded that EPO-R plays no role in tumor progression. This review provides a detailed insight into the nonhemopoietic role of EPO and its mechanism(s) of action which may lead to a better understanding of its potential therapeutic value in diverse clinical settings.

Abstract
OBJECTIVE To investigate whether the incidence of thromboembolic events (venous and arterial) increases when bevacizumab-based chemotherapy and erythropoietin stimulating agents (ESAs) are used in combination versus alone. METHODS A retrospective, pilot study of 79 colorectal cancer patients treated with chemotherapy were divided into 3 groups: bevacizumab (n = 28), ESA (n = 21), and bevacizumab plus ESA (n = 28). The primary end point was the incidence of thromboembolic events. Secondary endpoints included median time-to-event; effect of anticoagulation; and association with concurrent chemotherapy, baseline risk factors, hemoglobin, and performance status. RESULTS The incidence of thromboembolic events was 11% in the bevacizumab group, 23.8% in the ESA group, and 30% in the combination group (P = 0.194). The median time-to-event was 7.5, 3.5, and 2.5 months, respectively (P = 0.060). The 5 month difference in time-to-event between the bevacizumab group and combination group was significant (P = 0.045). When combining all patients, ESA treatment, prior venous thromboembolic event (VTE), obesity, cardiac disease, and use of exogenous hormones were strong predictors for thromboembolic events. Prior VTE was a strong predictor in those patients in the combination group. CONCLUSION The incidence of thromboembolic events was increased with the combination of bevacizumab plus ESA compared with either agent alone with chemotherapy. Median time-to-event in the combination group was significantly shorter compared with the bevacizumab group. Prior VTE, cardiac disease, obesity, and exogenous hormone use should be taken in consideration when using the combination of bevacizumab and ESAs.

Abstract
Venous thromboembolism (VTE) is common in cancer and is associated with both morbidity and mortality. Erythropoiesis stimulating agents (ESAs) were originally developed to correct anemia. Recent trials in cancer patients however, raise concerns over both increased VTE rates and the possibility of worse tumour outcomes and increased mortality with ESA use. The most common reason offered for explaining the possible negative impact of ESAs on cancer outcomes has been the stimulation of erythropoietin receptors on tumour cells. Despite an extensive literature, it is unlikely that most practicing appreciate the intricate relationship and interaction between the coagulation pathways, angiogenesis and tumour progression and ESA effects. This paper will review these connections and interactions and examine the hypothesis that other mechanisms may underlie the possible negative impact of ESAs on cancer outcomes.

Abstract
BACKGROUND AND OBJECTIVE Anemia is commonly observed in lung cancer (LC). Hemoglobin levels at the time of diagnosis could be considered a prognostic indicator in patients with LC. The aim of this trial was to analyze hemoglobin levels at the time of diagnosis as a prognostic factor in patients with LC. PATIENTS AND METHOD We retrospectively examined all patients with LC (cytologically or histologically confirmed) diagnosed in our health area for a period of 3 years. Correlation between hemoglobin levels and survival was assessed. All patients were divided into 2 groups: patients with low hemoglobin levels (lower than percentile 25 of the distribution), and patients who exceeded that figure. By means of Cox's regression, the influence of hemoglobin levels in survival was calculated and adjusted to other factors. RESULTS 421 patients were included, 52.2% of them presented anemia at the time of diagnosis. Mean age was 65.8 years and 92.7% were male. The group of patients with hemoglobin levels lower than percentile 25 had a survival rate that was 41% inferior. CONCLUSIONS Low hemoglobin levels are associated with decreased survival in patients with LC. The evaluation of this parameter could be used for a more accurate prognosis in LC and a better adequacy of therapeutic indications.

Abstract
Guidelines for the management of cancer-related fatigue (CRF) emphasize evidence-based strategies for reducing this common symptom in patients with cancer. Exercise has the largest body of data supporting its benefits in reducing CRF. Patient education and counseling also are considered integral to effective CRF management. Additional interventions can be pharmacologic or nonpharmacologic, although a combination of approaches may be employed. Several factors known to be associated with CRF may be particularly amenable to treatment.

Abstract
The impact of erythropoiesis-stimulating agent (ESA) on cancer patients' survival has recently become a matter of extensive discussion. Studies in solid tumors demonstrated that ESA adversely affects survival. This issue has not been sufficiently studied in patients with multiple myeloma. In this study, which included 323 multiple myeloma patients followed in our Institution between 1988 and 2007, we demonstrated by using a proportional hazards model including multiple covariates (age, LDH, Hb, platelets, serum creatinine, ISS score, beta2 microglobulin, and ESA administration) that ESA administration is associated with reduced survival (hazards ratio: 1.88, 95% CI: 1.28-2.77). Anemia, which is considered a predictor for survival, platelets, serum creatinine, ISS score, and LDH, were not significant, whereas, age and beta2 microglobulin confirmed their predicting value in the multivariate analysis. With a median follow-up of 31 months (range 1-238), the median survival of patients in the ESA group was 31 months (95% CI: 25-37), whereas in the group without ESA administration it was 67 months (95% CI: 55-79) (P < 0.001). The median progression-free survival for patients in the ESA group was 14 months (95% CI: 12-16), and for the group without ESA it was 30 months (95% CI: 24-36) (P < 0.001). These results indicate that ESA may have a detrimental impact on MM patients' outcomes and, thus, in this context, they should be used with rigorous criteria.

Abstract
PURPOSE/OBJECTIVES To determine the effect of aerobic and strength resistance training and epoetin alfa (EPO) therapy on transfusions, stem cell collections, transplantation recovery, and multiple myeloma treatment response. DESIGN Randomized clinical trial. SETTING A myeloma research and therapy center in the south central United States. SAMPLE 135 patients with multiple myeloma, 120 evaluable. METHODS Random assignment to exercise or usual care groups. All patients received EPO based on an algorithm. Aerobic capacity, using the six-minute walk test, was assessed prior to induction chemotherapy, prior to stem cell mobilization, and following stem cell collection for all patients and before and after transplantation for patients continuing in the study. Data analysis included analysis of variance to compare other outcome variables by groups. MAIN RESEARCH VARIABLES Number of red blood cell and platelet transfusions during transplantation, number of attempts at and total number of days of stem cell collection, time to recovery after transplantation, and response to intensive therapy for multiple myeloma. FINDINGS Recovery and treatment response were not significantly different between groups after transplantation. The exercise group had significantly fewer red blood cell transfusions and fewer attempts at stem cell collection. Serious adverse events were similar in each group. CONCLUSIONS Exercise with prophylactic EPO therapy reduces the number of RBC transfusions and attempts at stem cell collection for patients receiving intensive treatment for multiple myeloma. IMPLICATIONS FOR NURSING Exercise is safe and has many physiologic benefits for patients receiving multiple myeloma treatment.

Abstract
Anaemia often occurs in cancer patients and its origin is multifactorial, resulting from either bone marrow infiltration of cancer cells or cytotoxic effects produced by chemotherapy and radiotherapy. Anaemia impacts significantly on quality of life and appears markedly to limit disease control. Erythropoietin stimulates erythrocyte formation and the human recombinant form is useful in treating anaemia in cancer patients. Over the past decade erythropoietin has been associated with amelioration of anaemia and reduced need for blood transfusions. Nevertheless, several pre-clinical and clinical trials, employing relatively high doses of erythropoietin, have been halted recently following increased mortality and morbidity, primarily due to thrombotic events and possible tumour growth stimulation. It is, therefore, too early to know whether erythropoietin is useful in controlling morbidity and mortality in cancer-related anaemia. The risk-benefit of erythropoietic agents should be studied in carefully controlled trials. This review discusses prevalent issues and addresses key questions concerning the use of erythropoietic agents for the treatment of cancer-related anaemia.

Abstract
Autonomic neuropathy is a significant diabetic complication resulting in increased morbidity and mortality. Studies of autopsied diabetic patients and several rodent models demonstrate that the neuropathologic hallmark of diabetic sympathetic autonomic neuropathy in prevertebral ganglia is the occurrence of synaptic pathology resulting in distinctive dystrophic neurites ("neuritic dystrophy"). Our prior studies show that neuritic dystrophy is reversed by exogenous IGF-I administration without altering the metabolic severity of diabetes, i.e. functioning as a neurotrophic substance. The description of erythropoietin (EPO) synergy with IGF-I function and the recent discovery of EPO's multifaceted neuroprotective role suggested it might substitute for IGF-I in treatment of diabetic autonomic neuropathy. Our current studies demonstrate EPO receptor (EPO-R) mRNA in a cDNA set prepared from NGF-maintained rat sympathetic neuron cultures which decreased with NGF deprivation, a result which demonstrates clearly that sympathetic neurons express EPO-R, a result confirmed by immunohistochemistry. Treatment of STZ-diabetic NOD-SCID mice have demonstrated a dramatic preventative effect of EPO and carbamylated EPO (CEPO, which is neuroprotective but not hematopoietic) on the development of neuritic dystrophy. Neither EPO nor CEPO had a demonstrable effect on the metabolic severity of diabetes. Our results coupled with reported salutary effects of EPO on postural hypotension in a few clinical studies of EPO-treated anemic diabetic and non-diabetic patients may reflect a primary neurotrophic effect of EPO on the sympathetic autonomic nervous system, rather than a primary hematopoietic effect. These findings may represent a major clinical advance since EPO has been widely and safely used in anemic patients due to a variety of clinical conditions.

Abstract
Anemia is a frequent problem in cancer patients, especially in those treated with chemotherapy, and has an important negative impact on quality of life. Red blood cell transfusions provide clear but rather temporary comfort. The development of erythropoietic stimulating agents (ESAs) led to a more durable anemia treatment. Darbepoetin alpha is a unique ESA with a long plasma half life, thereby suitable for administration with different dosing intervals. Apart from administration every week, darbepoetin alpha also proved to be efficient in reducing red blood cell transfusion rates and in improving health-related quality of life when administered at a dose of 500 microg once every 3 weeks. This is a convenient therapy schedule because it can be synchronized with the chemotherapy cycle in many patients. Recently, concerns have been raised about the long-term safety of ESAs, more specifically about their effect on survival. Available data must be interpreted with caution, but at present there is no clear evidence to support a negative effect on outcome with darbepoetin alpha therapy when used according to the guidelines for treatment of chemotherapy-induced anemia. Further studies focusing on survival as the primary end point are ongoing.

Abstract
The use of recombinant adenoviruses (Ad) to express secreted antagonists of growth factors represents a powerful strategy for studying physiologic functions of growth factor pathways in experimental animals. Indeed, a single adenoviral injection can produce characteristic high-level and persistent plasma expression of soluble receptor ectodomains or secreted protein antagonists, allowing highly stringent conditional inactivation of target pathways in vivo. In this review, we describe our experience using recombinant Ad to inactivate growth factor pathways in vivo and discuss their advantages and limitations. Using our studies on vascular endothelial growth factor and Wnt systems as examples, we further describe how recombinant Ad can unveil previously unknown physiological roles of signaling pathways. Finally, we discuss the potential physiological and therapeutic relevance of our findings.

Abstract
Cancer-related fatigue has a significant impact on patients' physical and psychosocial functioning, symptom distress, and quality of life, yet it remains under-recognized and undertreated. The Oncology Nursing Society's Putting Evidence Into Practice initiative sought to improve patient outcomes relative to this important problem by critically examining and summarizing the evidence base for interventions to prevent and manage fatigue during and following treatment. This article critically reviews and summarizes the available empirical evidence regarding interventions for cancer-related fatigue. In addition to offering patients and clinicians a tool to facilitate effective management of the distressing symptom, this evidence-based review identifies gaps in knowledge and research opportunities.

Abstract
Erythropoietin (EPO) is a glycoprotein hormone produced by renal tissue in response to hypoxia; EPO functions as a cytokine to precursor cells produced by the bone marrow, stimulating red blood cell production. Erythropoiesis stimulating agents (ESAs) are manufactured molecules designed to mimic the ability of endogenous EPO to bind to EPO receptors and increase red blood cell production. To achieve desired dosing schedules and avoid the need for blood transfusions, oncologists have become increasingly reliant on ESAs to counter the anemia often experienced during chemotherapy. In recent years, significant concerns have been raised about the safety of ESAs, including the possibility of increased cardiovascular events and even increased tumor growth and accelerated mortality in cancer patients. ESAs also contribute significantly to the expense of chemotherapy, rendering them unavailable to some patients and available to others only upon achieving insurance-mandated levels of anemia. A recently discovered "normobaric oxygen paradox" demonstrates that renal tissue can be stimulated to increase EPO production via a simple pattern of oxygen breathing at normal atmospheric pressures. This leads directly to the hypothesis that oxygen breathing may provide chemotherapy patients with a convenient and inexpensive alternative to ESAs. Stimulating endogenous EPO production eliminates the small risk of immune system reaction associated with ESAs. Further, the endogenous physiological EPO doses provided by this method may be safer, in terms of cancer mortality, than the exogenous pharmacological doses inherent in ESA administration. A single patient test case is presented to support the hypothesis that normobaric oxygen breathing can be an effective replacement for ESAs in treating chemotherapy-induced anemia. In this case, a stage III breast cancer patient undergoing dose-dense AC+T chemotherapy obtained a clear response equivalent to ESA treatment by using a pattern of simple oxygen breathing.

Abstract
Erythropoietin has been successfully used in Europe since 1997 in the treatment of anemia induced by chemotherapy of solid tumors. There is only limited experience with regard to its use when treating dermatologic tumors such as metastatic melanoma. We review here current guidelines on the use of erythropoietin in cancer patients and report on our own melanoma patients treated with erythropoietin for chemotherapy-induced anemia.

Abstract
PURPOSE Previous trials have suggested a quality-of-life (QOL) improvement for anemic cancer patients treated with erythropoietin, but few used QOL as the primary outcome. We designed a trial to investigate the effects of epoetin alfa therapy on the QOL of anemic patients with advanced non-small-cell carcinoma of the lung (NSCLC). PATIENTS AND METHODS A multicenter, randomized, double-blind, placebo-controlled trial was conducted. The proposed sample size was 300 patients. Eligible patients were required to have NSCLC unsuitable for curative therapy and baseline hemoglobin (Hgb) levels less than 121 g/L. Patients were assigned to 12 weekly injections of subcutaneous epoetin alpha or placebo, targeting Hgb levels between 120 and 140 g/L. The primary outcome was the difference in the change in Functional Assessment of Cancer Therapy-Anemia scores between baseline and 12 weeks. RESULTS Reports of thrombotic events in other epoetin trials prompted an unplanned safety analysis after 70 patients had been randomly assigned (33 to the active arm and 37 to the placebo arm). This revealed a significant difference in the median survival in favor of the patients on the placebo arm of the trial (63 v 129 days; hazard ratio, 1.84; P = .04). The Steering Committee closed the trial. Patient numbers compromised the interpretation of the QOL analysis, but a positive Hgb response was noted with epoetin alfa treatment. CONCLUSION An unplanned safety analysis suggested decreased overall survival in patients with advanced NSCLC treated with epoetin alfa. Although infrequent, other similar reports highlight the need for ongoing trials evaluating erythropoietin receptor agonists to ensure that overall survival is monitored closely.

Abstract
UNLABELLED We conducted a national retrospective survey on hospital practitioners to evaluate the magnitude of erythropoietin (EPO) or granulocyte colony-stimulating factor (G-CSF) prescriptions in patients treated for chronic hepatitis C. Four hundred seventy-one questionnaires were sent, and 274 practitioners (58.2%) responded. Forty-six percent of practitioners used EPO, and 31% used G-CSF. The total number of HCV-infected patients receiving antiviral therapy per year was estimated at 6,630 patients, of whom 8.8% and 4% received EPO and G-CSF, respectively. EPO-beta was the main EPO molecule prescribed at a median dose of 30,000 IU/wk (range: 2,000-80,000). The indications for prescribing EPO varied greatly, including "fragile patients" (34%), "low" Hb level (8-11 g/dL) (19%), "rapid decline" in Hb level (2-5 g/dL during the first month of therapy) (12%), and symptomatic anemic patients (7%). G-CSF was mainly prescribed for a "low" level of neutrophils ranging from 400 to 750 neutrophils/mm3. In multivariate analysis, independent predictors of EPO and G-CSF prescription were age of practitioner less than 45 years (EPO: OR = 1.96, P = 0.03; G-CSF: OR = 2.27, P = 0.004), practice in university hospital (EPO: OR = 5.89, P < 0.0001; G-CSF: OR = 2.39, P = 0.003), and the high number of CHC treated/year (EPO: OR = 6.18, P < 0.0001; G-CSF: OR = 2.58, P = 0.002). CONCLUSION Our survey reveals an important rate of EPO and G-CSF prescriptions but with considerable disparity in the schedule of injections, the molecules used, and above all the indications. The suitable role of EPO and G-CSF as complements to HCV therapy urgently needs to be clarified.

Abstract
BACKGROUND In this study, the development and validation of a cycle-based prediction model for severe anemia [i.e., a hemoglobin (Hb) of <or=100 g/l] in patients with advanced nonsmall cell lung cancer (NSCLC) receiving palliative chemotherapy is described. MATERIALS AND METHODS Data on 536 European patients who were receiving palliative chemotherapy were prospectively collected as part of the European Cancer Anemia Survey [Ludwig et al., Eur J Cancer 40:2293-2306, 2004]. The patient sample was then randomly divided into two-thirds model derivation and one-third validation sample. A third external sample consisting of 76 patients treated at the Toronto Sunnybrook Regional Cancer Centre was separately used to externally validate the model. Multivariable logistic regression techniques were applied to develop the initial model. A risk scoring system based on the regression parameters was then created ranging from 0 to 15. RESULTS Precycle Hb, patient body surface area, advanced age, poor performance status, recurrent or persistent disease, and the use of platinum or gemcitabine-based chemotherapy were identified as important predictors for anemia. A prechemotherapy risk score of >or=8 to <10 was identified as the optimal cut off to maximize the sensitivity (83.1%) and specificity (67.8%) of the prediction tool. Patients with a score of >or=8 would be considered at high risk for developing anemia after a particular cycle of chemotherapy. DISCUSSION We developed and validated an anemia prediction tool for advanced stage NSCLC patients receiving palliative chemotherapy. To make the model available for easy use and access, we have incorporated it on to our risk prediction website: http://www.PredictPatientEvents.com . It is hoped that this risk model will enhance patient care by optimizing the frequency of Hb testing and/or the use of preventative therapies.

Abstract
PURPOSE Cancer-related fatigue contributes to negative outcomes relative to psychosocial and symptom distress, functional status, and quality of life, and yet it is often underdiagnosed and management is frequently suboptimal. DESIGN Systematic database searches were conducted, and primary research reports and meta-analyses of quantitative studies of interventions for fatigue published in English were identified and critically examined. RESULTS This paper reviews the etiology and evaluation of cancer-related fatigue and analyzes current empirical evidence supporting pharmacologic and nonpharmacologic techniques for its management. DISCUSSION A variety of pharmacologic and nonpharmacologic techniques to manage cancer-related fatigue have been studied, although most of the evidence is from single-arm pilot studies with small sample sizes, rather than from adequately powered, multicenter, randomized controlled trials. Continued research in ethnically and racially diverse samples is needed to identify the interventions that are most effective in specific cancer subpopulations and to develop and test interventions for fatigue at each phase in the illness trajectory.

Abstract
PURPOSE To compare maintenance epoetin alfa administered once every 3 weeks with continued weekly epoetin alfa for patients with cancer-associated anemia. PATIENTS AND METHODS Eligible patients were randomly assigned at enrollment to receive three weekly doses of epoetin alfa 40,000 U subcutaneously (SC), followed by either standard weekly epoetin alfa (40K arm) or 120,000 U of epoetin alfa (120K arm) SC every 3 weeks for 18 additional weeks. RESULTS Three hundred sixty-five patients were enrolled. One hundred eighty-three patients were assigned to the 40K arm, and 182 were assigned to the 120K arm. There was no difference in the proportion of patients requiring transfusions during the study (23% in 40K arm and 18% in 120K arm, P = .22) or specifically during the maintenance phase (13% in 40K arm v 15% in 120K arm, P = .58). Patients randomly assigned to the 40K arm were more likely to have a > or = 2 or > or = 3 g/dL hemoglobin (Hb) increment, were more likely to have a drug dose held because of high Hb, and had higher mean end-of-study Hb levels. Toxicities, including thromboembolism, and overall survival were similar. Patients in the 40K arm had a higher global quality of life (QOL) at baseline for unclear reasons, whereas patients in the 120K arm had a greater global QOL improvement during the study, so end-of-study QOL was equivalent. CONCLUSION After three weekly doses of epoetin alfa 40,000 U, a dose of 120,000 U can be administered safely once every 3 weeks without increasing transfusion needs or sacrificing QOL. The Hb increment is somewhat greater with continued weekly epoetin alfa. Lack of blinding as a result of different treatment schedules may have confounded results.

Abstract
The myelodysplastic syndromes (MDSs) are common, acquired, clinically challenging hematologic conditions that are characterized by bone marrow failure and a risk of progression to acute leukemia. These disorders can arise de novo, especially in elderly patients or, less often, as a consequence of prior chemotherapy or radiotherapy for an unrelated disease. The MDS classification systems were revised recently and updated. These refined classification and prognostic schemes help stratify patients by their risk of leukemia progression and death; this knowledge can help clinicians select appropriate therapy. Although many treatments for MDS have been proposed and evaluated, at present, only hematopoietic stem cell transplantation offers any real hope for cure, and no available therapy beyond general supportive care offers benefit to more than a minority of patients. However, recent clinical trials enrolling patients with MDS have reported encouraging results with use of newer drugs, including lenalidomide, decitabine, and darbepoetin alfa. Other exciting treatment regimens are being tested. Here, we present a contemporary, practical clinical approach to the diagnosis and risk-stratified treatment of MDS. We review when to suspect MDS, detail how to evaluate patients who may have a form of the condition, explain key features of treatments that are currently available in the United States, and summarize a general, common-sense therapeutic approach to patients with MDS.
