Abstract
OBJECTIVES The study examined the impact of chemotherapy-induced neutropenic complications (CINC), defined as neutropenia with fever or infection, on short-term disability (STD) among cancer patients receiving chemotherapy. METHODS The key outcome metrics were average monthly STD days and associated indirect costs. Patients with and without CINC were propensity score (PS) matched. Multivariate regressions were conducted on PS-matched cohorts to estimate the marginal impact of CINC. RESULTS A total of 280 patients with CINC were PS-matched to 280 patients without CINC. Compared with matched patients, patients with CINC on average experienced 0.9 more STD day (3.2 vs. 2.3, p=0.046) and $155 more in indirect costs ($549 vs. 394, p=0.050) per month. After multivariate adjustment, patients with CINC experienced 1.0 more STD day (p=0.029), and incurred $200 more in indirect cost (p=0.016) per month. CONCLUSIONS Patients with CINC experience significantly greater STD leave than patients with no neutropenic complications from cancer chemotherapy. The overall study sample only included patients from large self-insured employers in the US and may not reflect the work loss experience of all employed patients in the US or other countries. Indirect costs associated with absenteeism and presenteeism were not measured.

Abstract
Medical practice is increasingly informed by the evidence from randomized controlled trials. When such evidence is not available, clinical hypotheses based on pathophysiological reasoning and common sense guide clinical decision making. One commonly utilized general clinical hypothesis is the assumption that normalizing abnormal laboratory values and physiological parameters will lead to improved patient outcomes. We refer to the general use of this clinical hypothesis to guide medical therapeutics as the "normalization heuristic". In this paper, we operationally define this heuristic and discuss its limitations as a rule of thumb for clinical decision making. We review historical and contemporaneous examples of normalization practices as empirical evidence for the normalization heuristic and to highlight its frailty as a guide for clinical decision making.

Abstract
BACKGROUND Granulopoiesis-stimulating factors, such as granulocyte-colony-stimulating factor (G-CSF) and granulocyte-macrophage-colony-stimulating factor (GM-CSF), are being used to prevent febrile neutropenia and infection in patients undergoing treatment for malignant lymphoma. The question of whether G-CSF and GM-CSF improve dose intensity, tumour response, and overall survival in this patient population has not been answered yet. Since the results from single studies are inconclusive, a systematic review was undertaken. OBJECTIVES To determine the effectiveness of G-CSF and GM-CSF in patients with malignant lymphoma with respect to preventing neutropenia, febrile neutropenia and infection; improving quality of life, adherence to treatment protocol, tumour response, freedom from treatment failure (FFTF) and overall survival (OS); and adverse effects. SEARCH STRATEGY We searched The Cochrane Library, MEDLINE, EMBASE, CancerLit, and other relevant literature databases; Internet databases of ongoing trials; and conference proceedings of the American Society of Clinical Oncology and the American Society of Hematology (1980 - 2007). We included full-text and abstract publications as well as unpublished data. SELECTION CRITERIA Randomised controlled trials comparing prophylaxis with G-CSF or GM-CSF versus placebo/no prophylaxis in adult patients with malignant lymphoma undergoing chemotherapy were included for review. Both study arms had to receive identical chemotherapy and supportive care. DATA COLLECTION AND ANALYSIS Trial eligibility and quality assessment, data extraction and analysis were done by two reviewers independently. Authors were contacted to obtain missing data. MAIN RESULTS We included 13 eligible randomised controlled trials with 2607 randomised patients. Compared with no prophylaxis, both G-CSF and GM-CSF did not improve overall survival (hazard ratio 0.97; 95% CI 0.87 to 1.09) or FFTF (hazard ratio 1.11; 95% CI 0.91 to 1.35). Prophylaxis significantly reduced the relative risk (RR) for severe neutropenia (RR 0.67; 95% confidence interval (CI) 0.60 to 0.73), febrile neutropenia (RR 0.74; 95% CI 0.62 to 0.89) and infection (RR 0.74; 95% CI 0.64 to 0.85). There was no evidence that either G-CSF or GM-CSF reduced the number of patients requiring intravenous antibiotics (RR 0.82; 95%CI 0.57 to 1.18); lowered infection related mortality (RR 0.93; 95% CI 0.51 to 1.71); or improved complete tumour response (RR 1.03; 95% CI 0.95 to 1.10).One study evaluated quality of life parameters and found no differences between the treatment groups. AUTHORS' CONCLUSIONS G-CSF and GM-CSF, when used as a prophylaxis in patients with malignant lymphoma undergoing conventional chemotherapy, reduce the risk of neutropenia, febrile neutropenia and infection. However, based on the randomised trials currently available, there is no evidence that either G-CSF or GM-CSF provide a significant advantage in terms of complete tumour response, FFTF or OS.

Abstract
X-linked agammaglobulinemia (XLA) is a primary B-cell deficiency syndrome with an incidence of 5 to 10 cases per million. The current treatment approach includes intravenous immunoglobulin and aggressive antibiotic regimens for infections. Besides recurrent infections, XLA patients may present with other manifestations, such as alopecia, enteropathy, amyloidosis, and neutropenia. Neutropenia, which has been shown in up to 25% of affected patients, might also contribute to the degree of severity of bacterial infections that have been reported in these cases. Here we present our experience with the granulocyte colony-stimulant factor, filgrastim (Neupogen), in the treatment of neutropenia in a 14-month-old child with XLA.

Abstract
Effects of fractions A and B from enzyme-digested traditional Chinese medicine colla corii asini on mice with 5-fluorouracil-induced anemia were investigated. The purpose of this study was to further understand the hematopoietic activities and mechanisms of colla corii asini. The fractions A and B were administered to anemic mice for 12 days. After confirming the anti-anemic effect of fractions A and B, we examined the effects of fractions A and B on immature granulocyte and erythroid cell activity and plasma cytokine level. Fraction A administration at 2 g/kg and 1 g/kg and fraction B administration at 1.6 g/kg and 0.8 g/kg activated granulocyte and erythrocyte progenitor cells in bone marrow and erythrocyte progenitors in spleen, led to the recovery of white blood cell and red blood cell counts, and increased the percentage of peripheral reticulocytes in red cells. The GM-CSF and EPO production determined by examining GM-CSF mRNA and EPO mRNA in the kidney and liver of the anemic mice were also enhanced. This treatment significantly increased serum GM-CSF and EPO level and lowered serum transforming growth factor (TGF-beta) level. These results suggested that fractions A and B promoted hematopoiesis by activating immature granulocyte and erythroid cells, partly by stimulating GM-CSF and EPO secretion and suppressing TGF-beta release. Identification of a specific peptide or protein is still required for the development of a novel medicine for anemia caused by malignancy or chemotherapy.

Abstract
PURPOSE Randomized controlled trials (RCTs) of prophylactic granulocyte colony-stimulating factors (G-CSF) have demonstrated a significant reduction in febrile neutropenia (FN) after systemic chemotherapy. Several RCTs have been published recently that investigate the impact of G-CSF on mortality and relative dose-intensity (RDI). METHODS A comprehensive systematic review and meta-analysis of all reported RCTs comparing primary prophylactic G-CSF with placebo or untreated controls in adult solid tumor and malignant lymphoma patients was undertaken without language restrictions, using electronic databases, conference proceedings, and hand-searching techniques. Two reviewers extracted data independently. Summary estimates of relative risk (RR) with 95% CIs were estimated based on the method of Mantel-Haenszel and DerSimonian and Laird. RESULTS Seventeen RCTs were identified including 3,493 patients. For infection-related mortality, RR reduction with G-CSF compared with controls was 45% (RR = 0.55; 95% CI, 0.33 to 0.90; P = .018); for early mortality (all-cause mortality during chemotherapy period), it was 40% (RR = 0.60; 95% CI, 0.43 to 0.83; P = .002); and for FN, it was 46% (RR = 0.54; 95% CI, 0.43 to 0.67; P < .001). Average RDI was significantly higher in patients who received G-CSF compared with control patients (P < .001). Bone or musculoskeletal pain was reported in 10.4% of controls and 19.6% of G-CSF patients (RR = 4.03; 95% CI, 2.15 to 7.52; P < .001). Significant reductions in FN with G-CSF were observed in studies allowing secondary G-CSF prophylaxis in controls and in the three trials with concurrent prophylactic antibiotics in both treatment arms. CONCLUSION Prophylactic G-CSF reduces the risk of FN and early deaths, including infection-related mortality, while increasing RDI and musculoskeletal pain. There are insufficient data to assess the impact of G-CSF on disease-free and overall survival.

Abstract
OBJECTIVE Patients receiving cancer treatments commonly experience haematological adverse effects (AEs) related to chemotherapy or molecularly targeted therapies, which may be associated with high healthcare costs. The objective of this review was to summarise the published literature on the economic burden of neutropenia, thrombocytopenia and anaemia as AEs of cancer treatment. METHODS A systematic search of the medical literature published between 1990 and 2006 was conducted using PubMed/MEDLINE, EMBASE, BIOSIS, related article links and supplemental searches. References selected for inclusion were prospective or retrospective studies specifically designed to examine the burden of illness, direct medical costs, indirect costs and/or cost drivers associated with neutropenia, thrombocytopenia and anaemia in adult cancer patients. All costs are reported as originally published and adjusted to 2006 US dollars. RESULTS In the US, the cost of neutropenia ranged from $US 1893 (2006 value $US 2632) per outpatient episode to $US 38,583 ($US 49,917) per febrile neutropenia hospitalisation. For countries outside the US, the cost of neutropenia appeared to be lower. The cost of thrombocytopenia ranged from $US 1035 ($US 1395) to $US 5328 ($US 7635) per cycle or episode in the US. Costs attributable to anaemia ranged from $US 18,418 ($US 22,775) to $US 69,478 ($US 93,454) per year in the US. The costs of AEs for patients with haematological malignancies appeared to be up to 2-3 times higher than those for patients with solid tumours. Economic studies of the cost of haematological AEs specific to new molecularly targeted treatments for haematological malignancy have not been published. CONCLUSIONS Chemotherapy-related haematological AEs result in a substantial economic burden on patients, payers, caregivers and society in general. Because of their burden, the frequency and severity of these toxicities should be one of the key factors in the selection of optimal treatments for patients with cancer, especially those with haematological malignancies. Future research is needed to assess the economic burden of AEs associated with new molecularly targeted treatments for haematological malignancies.

Abstract
BACKGROUND Platinum-based chemotherapy is standard treatment for patients with advanced lung cancer. The common side effect of this therapy is myelosuppression, for which different stimulating factors are used. In this article, the effect of granulocyte colony-stimulating factor (G-CSF) administration on the survival of patients with unresectable non-small-cell lung cancer (NSCLC) was evaluated. METHODS The charts of 127 patients, treated with carboplatin-based chemotherapy, were reviewed for histology, stage, performance status, weight loss, treatment regimen, toxicity, and survival. Eighty patients were stage IIIA/IIIB NSCLC; 47 were stage IIIB (pleural effusion) or stage IV. Eighty-one patients (63%) experienced severe (grades 3 and 4) neutropenia. Forty-two patients received G-CSF, 37 patients for severe neutropenia (14 with febrile neutropenia) and five patients for active infection during chemotherapy. RESULTS Preliminary analyses, both unadjusted (median survival, 20 months versus 13.8 months; log-rank test, p = 0.02) and adjusted for covariates of interest (Cox regression, hazard ratio = 0.62, p = 0.03) showed a significant effect of the use of G-CSF on survival, even though the groups were balanced with respect to stage, performance status, weight loss, and dose intensity of chemotherapy. Patients with grades 3 and 4 neutropenia (whether they received G-CSF or not) had a better survival outcome compared to those who did not have neutropenia (median survival, 17.6 months versus 11.9 months, log-rank test, p = 0.04). A landmark analysis showed a marginally significant effect of G-CSF on survival (median survival, 18.6 months versus 15.1 months, log-rank test, p = 0.08), even after adjustment for covariates. The Cox regression with the use of G-CSF defined as a binary time-varying covariate also showed similar results (Cox regression, hazard ratio = 0.67, 95% CI: 0.42-1.04, p = 0.07). CONCLUSION In this study, the time bias due to the delayed administration of G-CSF contributed to the longer survival of patients receiving G-CSF. Prospective studies are required to determine whether G-CSF has any effect on survival in patients with advanced NSCLC.

Abstract
BACKGROUND We aimed to improve the postoperative outcome of high-risk patients (American Society of Anesthesiologists class 3 and 4) recovering from colorectal cancer surgery by using recombinant human G-CSF (filgrastim) as perioperative prophylaxis. METHODS In a double-blinded, placebo-controlled trial, 80 patients undergoing left-sided colorectal resection were randomized to filgrastim or placebo. Filgrastim (5 mug/kg) or placebo was administered in the afternoon on day -1, 0, and +1 relative to the operation. Primary endpoints were in a hierarchic order: quality of life (QoL) over time (determined at discharge, 2 and 6 months after operation with the European Organization for Research and Treatment of Cancer questionnaire) and the McPeek recovery score, which measures death and duration of stays in the intensive care unit and hospital. Predefined secondary endpoints were global QoL, subdomains of QoL, postoperative recovery, duration of stay, 6-month overall survival, complication rates, and cellular and immunologic parameters. RESULTS There were no significant differences in both primary endpoints between the treatment groups. A significant improvement (P < .05) was obtained by filgrastim prophylaxis in the QoL subdomain family life /- social functioning,; thus, more patients recovered to their preoperative state (14 vs 4 with placebo) as determined by structured interviews. Duration of hospital stay (14 vs 12 days) and noninfectious complications were decreased from 8% to 3%. CONCLUSIONS High-risk patients undergoing major operation for colorectal cancer profited from filgrastim prophylaxis with regard to duration of hospital stay, noninfectious complications, social QoL, and subjective recovery from operation. These endpoints, however, were secondary, and the primary endpoints (overall QoL and the McPeek index) did not show comparable benefits. A new confirmatory trial with the successful endpoints of this trial, as well as a cost analysis, will be needed to confirm the results before a general recommendation for the prophylactic use of G-CSF in high-risk cancer patients can be given.

Abstract
BACKGROUND We investigated whether administration of full-dose ABVD (Adriamycin, bleomycin, vinblastine, dacarbazine) chemotherapy without growth factors, and irrespective of the granulocyte count, caused treatment delays or increased the number of infective episodes, in patients with Hodgkin's lymphoma (HL). PATIENTS AND METHODS Thirty-eight patients with confirmed predominantly early-stage HL were treated with ABVD outside clinical trial protocols over a 5-year period on an outpatient basis. RESULTS Ninety-five per cent of patients completed their scheduled ABVD regimen without adverse effects despite the development of neutropenia. Anaemia and thrombocytopenia did not present problems. Febrile neutropenia complicated 0.57% of combination chemotherapy injections. No growth factors were used and no dose modifications were carried out apart from the omission of bleomycin in one patient for the last two cycles of treatment due to the development of lung toxicity. All patients are currently disease-free, although three (7.8%) required salvage high-dose therapy (one relapsed and two with refractory disease). CONCLUSIONS ABVD administration irrespective of granulocyte counts allowed the treatment to be given at full dose without delays or significant number of infective episodes. There was no need for growth factor support, minimising treatment costs. The use of full-dose ABVD irrespective of granulocyte count should be evaluated in future protocols for HL.

Abstract
The hematopoietic growth factors (HGFs) are a family of glycoproteins which plays a major role in the proliferation, differentiation, and survival of primitive hematopoietic stem and progenitor cells, and in the functions of some mature cells. More than 20 different molecules of HGF have been identified. Among them, granulocyte colony-stimulating factor (G-CSF) and granulocyte-macrophage colony-stimulating factor (GM-CSF) have been demostrated to be effective in reducing the incidence of febrile neutropenia when administered inmediately after chemotherapy and as supportive therapy in patients undergoing bone marrow transplantation. Chemotherapy used for treatment of cancer often causes neutropenia, which may be profound, requiring hospitalization, and leading to potentially fatal infection. The uses of the recombinant human hematopoietic colony-stimulating factors G-CSF and GM-CSF for treatment and prophylaxis of chemotherapy-induced febrile neutropenia will be reviewed here.

Abstract
BACKGROUND The colony-stimulating factors (CSFs) are widely utilized to prevent neutropenic complications in both adults and children, but randomized controlled trials in the pediatric setting have reported varied results. A systematic review of the literature and meta-analysis were conducted to definitively assess the impact of prophylactic CSFs on the risk of febrile neutropenia (FN) in pediatric oncology patients. METHODS MEDLINE was searched and references hand-searched through July 2004 for randomized controlled trials of prophylactic G-CSF or GM-CSF in pediatric oncology patients. Objectives, outcomes, and quality of the 16 included studies were extracted by two reviewers. Weighted summary estimates of relative risks (RR) were calculated for FN and documented infection (DI). Mean differences in hospitalization, antibiotic use, and duration of neutropenia were calculated. RESULTS FN occurred in 68% of 400 controls and 59% of 404 CSF patients. The estimated RR was 0.88 [0.81-0.97; (P=0.01)] favoring the CSFs for leukemia and high grade lymphoma studies and 0.71 [0.51-0.97; (P=0.03)] for solid tumor studies. DI occurred in 25% of controls and 20% of CSF patients for an estimated RR of 0.80 [0.61-1.06; (P=0.12)]. The mean decrease in duration of neutropenia was 3.5 days [2.2-4.7; (P<0.0001)]. Mean decreases favoring CSF use were also observed for hospital stay of 1.7 days [0.9-2.5 (P<0.01)] and antibiotic use of 2.0 days [0.4-3.6; P=0.02]. CONCLUSIONS Prophylactic CSFs significantly decrease the incidence of FN and the durations of severe neutropenia, hospitalization, and antibiotic use in pediatric cancer patients, but they do not significantly decrease documented infections.

Abstract
PURPOSE Hematopoietic growth factors have played a major role in preventing infection and shortening the duration of neutropenia in patients receiving cancer chemotherapy. Little information is available on how these growth factors are used in patients with cancer outside the clinical trial setting. We performed descriptive and exploratory analyses on the patterns and correlates of the use of hematopoietic growth factors in community-dwelling elderly patients. PATIENTS AND METHODS We identified 5,843 women from the Surveillance, Epidemiology, and End Results (SEER)-Medicare-linked data cohorts who were diagnosed with breast cancer at age 65 or older in 1992 to 1999 from the 11 SEER areas and received chemotherapy. RESULTS Overall, 17.3% of the elderly women with breast cancer chemotherapy received filgrastim and 6.8% received epoetin. The use of the growth factors increased significantly over time from 1992 to 1999 (P < .001 for trend). Compared with patients diagnosed in 1992 to 1994, patients diagnosed in 1998 to 1999 were more than five times and 65 times more likely to receive filgrastim and epoetin, respectively, after controlling for other factors such as age and comorbidity. There also was substantial geographic variation in the use of hematopoietic growth factors, ranging from 10.6% in Seattle to 22.9% in Atlanta. Significant predictors of growth factors included patient age, race, tumor stage, and comorbidity. CONCLUSION There were substantial temporal and geographic variations in the use of hematopoietic growth factors among patients receiving chemotherapy for breast cancer. The nationwide and population-based Medicare claims provide potential for examining the effectiveness, medical costs, and cost effectiveness of hematopoietic growth factors in the community.

Abstract
Recombinant granulocyte colony-stimulating factor (G-CSF) is used for cancer patients with myelosuppression induced by chemotherapy. G-CSF has been reported to progress tumor growth and angiogenesis, but the precise mechanism of tumor angiogenesis activated by G-CSF has not been fully clarified. N-terminal-mutated recombinant human G-CSF administration increased WBCs and neutrophils in peripheral blood and reduced bone marrow stromal cell-derived factor-1 in mice, indicating its biological relevance. Mice were inoculated with Lewis lung carcinoma cells (LLCs) or KLN205 cells and treated with G-CSF. G-CSF accelerated tumor growth and intratumoral vessel density, while it did not accelerate proliferation of LLCs, KLN205 cells or human umbilical vein endothelial cells in vitro. In the absence of tumors, G-CSF did not increase circulating cells that displayed phenotypic characteristics of endothelial progenitor cells (EPCs). In the presence of tumors, G-CSF increased circulating EPCs. In addition, G-CSF treatment increased immune suppressor and endothelial cell-differentiating Gr1+CD11b+ cells in tumor-bearing mice. We conclude that G-CSF promotes tumor growth by activating tumor angiogenesis via increasing circulating EPCs and Gr1+CD11b+ cells in cancer animal models.

Abstract
OBJECTIVE Patients with newly diagnosed cancer responsible for organ failures may require intensive care unit (ICU) admission and immediate chemotherapy. Outcomes in this population have not been studied. DESIGN Prospective observational cohort study. SETTING Teaching hospital. SUBJECTS All patients admitted to the ICU, from January 1997 to June 2003, for organ failures due to newly diagnosed, untreated cancer and deemed necessary to receive immediate cancer chemotherapy. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS For the period of 6.5 yrs, 100 patients met the study criteria: 43 had acute leukemia, 37 lymphoma, and 12 solid tumors. Median Simplified Acute Physiology Score II was 39 (30-48) points, and median Logistic Organ Dysfunction score was 5 (3-7) points. Three variables were independently associated with 30-day mortality: need for vasopressor therapy (odds ratio, 6.01; 95% confidence interval, 1.86-19.4), mechanical ventilation (odds ratio, 6.36; 95% confidence interval, 1.76-22.94); and hepatic failure (odds ratio, 7.76; 95% confidence interval, 1.25-48.27). Overall survival was 60% after 30 days and 49% after 180 days. CONCLUSIONS Mortality was chiefly dependent on the nature and number of organ failures, not on the nature or stage of the malignancy. The 30-day and 180-day survival rates indicate that, in this selected group of patients, advanced disease at cancer diagnosis should not lead to refusal of ICU admission. Moreover, administration of chemotherapy in the intensive care unit is feasible, and although the mortality rate is high, routine ICU admission of patients with newly diagnosed cancer, specific organ failure, and the need for administration of chemotherapy in the ICU deserves evaluation.

Abstract
PURPOSE/OBJECTIVES To provide an overview of the risks for and occurrence of chemotherapy-induced neutropenia in patients with cancer and its optimal prophylactic management with recombinant human granulocyte-colony-stimulating factor (G-CSF). DATA SOURCES Original research, review articles, conference presentations, and published guidelines. DATA SYNTHESIS Chemotherapy-induced neutropenia is a common serious adverse event, and the risks for it can be predicted on the basis of patient characteristics and the chemotherapy regimen. CONCLUSIONS Optimal, cost-effective prophylactic management of chemotherapy-induced neutropenia with G-CSF requires the assessment of patient factors and the myelotoxicity of the chemotherapy regimen. IMPLICATIONS FOR NURSING Neutropenia and its complications can be serious adverse events in patients who are treated with chemotherapy. Nurses should be familiar with how to identify patients who are at risk for neutropenia and its complications and should be prepared to discuss the need for first-cycle use of G-CSF with the other members of the treatment team as necessary.

Abstract
Granulocyte colony-stimulating factor (CSF) and granulocyte-macrophage CSF are potent drugs used to increase neutrophil counts after myelosuppressive chemotherapy. However, in various indications, the use of CSFs has no clinical benefit with regard to morbidity or mortality from infectious complications, frequency of antibiotic use, or rate of hospitalization. Thus, the application of CSFs should be limited to indications with proven clinical benefits or evidence of cost-effectiveness. This review will provide an overview of the state-of-the-art use of CSFs in chemotherapy-associated neutropenia, transplantation, and bone marrow failure syndromes. In addition, recently developed drugs for accelerated hematopoietic recovery will be presented.

Abstract
Concern about the commercialization of research is rising, notably in testing new drugs. The problem involves oversimplified, polarizing assumptions about research and development (R&D) and intellectual property (IP). To address this problem this paper sets forth a more complex three phase RT&D process, involving Scientific Research (R), Technological Innovation (T), and Commercial Product Development (D) or the RT&D process. Scientific research and innovation testing involve costly intellectual work and do not produce free goods, but rather require IP regulation. RT&D processes involve an unrecognized IP shift from a common IP right in public goods like information and knowledge to private IP in products and other hard assets. The question then is, what kind of IP right: private or common? Since scientific research and innovation testing require openness about adverse findings, and wide, low cost diffusion of results, they require a common, inclusive IP right. Common IP is appropriate to both sharing knowledge goods and recovering the cost of production. Research is furthermore compatible with commercialization and support by other social interests. On the other hand it is incompatible with the exclusionary private IP rights that permit restrictive publication or total suppression of information. Private IP rather than commercialization conflicts with the openness requirements of scientific research and innovation testing. Commercial funding, however, is in principle compatible with research and testing, especially when regulated by a common IP right. This reflects a pragmatic view of the fundamental interconnections of knowledge and other social interests.

Abstract
We report in this paper that a novel small molecule, JTZ-132, induced growth and differentiation of megakaryocytic progenitor cells and improved thrombocytopenia in myelosuppressed mice. JTZ-132 stimulated proliferation of UT-7/TPO cells, a cell line highly sensitive to thrombopoietin (TPO), and exhibited full efficacy comparable to TPO with an approximate EC50 (median effective concentration) value of 0.43 μM, whereas little proliferation was observed in a TPO-insensitive cell line, UT-7/EPO, and human carcinoma cell line, HCT116. Signal transduction studies revealed that JTZ-132 induced tyrosine phosphorylation of c-Mpl, Janus kinase-2 (JAK2), and signal transducers and activators of transcription 5 (STAT5) in UT-7/TPO cells as well as TPO. JTZ-132 increased the number of megakaryocyte-specific marker, CD61+ and CD41+, cells in cultures of mouse and human bone marrow cells, respectively, and the colonyforming unit megakaryocytes in mouse bone marrow cells. In vivo experiments in x-ray irradiation– or busulfan injection–induced myelosuppressed mice demonstrated that subcutaneously injected JTZ-132 at 30 mg/kg showed significantly higher platelet number at nadir and accelerated platelet recovery without affecting white blood cell number. These data suggest that JTZ-132 is a novel stimulator of megakaryocytopoiesis and thrombocytopoiesis in vitro and in vivo with TPO mimetic activities and that it is useful for the treatment of thrombocytopenia.

Abstract
AbstractHematopoietic cytokines such as filgrastim are used extensively to stimulate granulocyte production or to mobilize hematopoietic progenitors into the circulation; however, their effect on more primitive hematopoietic progenitor and stem cells in vivo is unknown, particularly in large animals or humans. In particular, there is concern that chronic therapy with cytokines could result in stem cell exhaustion or clonal dominance; however, direct assessment of the dynamics of individual stem and progenitor cell clones in vivo has not been previously reported. A number of models can be proposed regarding the mechanisms by which the marrow responds to cytokine stimulation, including recruitment of previously quiescent clones, stimulation of proliferation of already active clones, or prevention of apoptosis of more mature progenitors from all clones. Using retroviral marking and comprehensive insertion site tracking of individual stem and progenitor cell clones in 2 rhesus macaques, we analyzed the effect of chronic administration of granulocyte colony-stimulating factor (G-CSF), or a combination of G-CSF plus stem cell factor (SCF). The overall number of contributing clones remained constant, and the relative output from each clone did not change significantly during or following cytokine treatments. These results suggest that individual transduced stem or progenitor cells can contribute to hematopoiesis for prolonged periods, with no evidence for an effect of G-CSF or G-CSF/SCF on the number, the lifespan, or the relative activity of individual stem or progenitor cell clones. These relevant large animal studies are reassuring regarding clinical applications of cytokines and provide new insights into their mechanisms of action.

Abstract
Children with cancer receiving anticancer therapy always experience neutropenia, and as a result often develop serious neutropenic infections that cause morbidity and/or mortality. Intensive chemotherapy with improved supportive care for neutropenia contribute to the recent advances in treatment outcome in children with cancer. Recombinant human granulocyte colony-stimulating factor (G-CSF) and recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF) can shorten the duration and decrease the severity of neutropenia, and thus support intensive chemotherapy. Both G-CSF and GM-CSF stimulate proliferation and maturation of myeloid progenitor cells and are thus used to help mobilization of peripheral blood progenitor cells, and after stem-cell transplantation. The American Society of Clinical Oncology 2000 Guidelines recommended that colony-stimulating factors (CSFs) can be administered as a primary prophylaxis with a chemotherapy regimen if previous experiences with chemotherapy regimens have shown that the incidence of febrile neutropenia (neutropenic fever) is > or =40%. The routine use of CSFs for secondary prophylaxis or for patients with afebrile neutropenia is not recommended in order to avoid the overuse of CSFs. The use of a CSF may be considered in children with febrile neutropenia with a neutrophil count <100/microL, uncontrolled primary disease, pneumonia, hypotension, multiorgan dysfunction (sepsis syndrome), or invasive fungal infection. Although these guidelines are generally applicable to children with cancer, further studies on CSFs are certainly needed in pediatric oncology. The recent advances in granulocyte collection, using healthy volunteer donor stimulation with G-CSF and/or dexamethasone to yield large numbers of granulocytes has made granulocyte transfusion a more realistic option. Granulocyte transfusion has shown promising results in treating children with severe neutropenic infection; however, controlled trials are warranted to clarify the efficacy and cost-effectiveness of this procedure.

Abstract
Cytotoxic chemotherapy suppresses the hematopoietic system, impairing host protective mechanisms and limiting the doses of chemotherapy that can be tolerated. Neutropenia, the most serious hematologic toxicity, is associated with the risk of life-threatening infections as well as chemotherapy dose reductions and delays that may compromise treatment outcomes. The authors reviewed the recent literature to provide an update on research in chemotherapy-induced neutropenia and its complications and impact, and they discuss the implications of this work for improving the management of patients with cancer who are treated with myelosuppressive chemotherapy. Despite its importance as the primary dose-limiting toxicity of chemotherapy, much concerning neutropenia and its consequences and impact remains unknown. Recent surveys indicate that neutropenia remains a prevalent problem associated with substantial morbidity, mortality, and costs. Much research has sought to identify risk factors that may predispose patients to neutropenic complications, including febrile neutropenia, in an effort to predict better which patients are at risk and to use preventive strategies, such as prophylactic colony-stimulating factors, more cost-effectively. Neutropenic complications associated with myelosuppressive chemotherapy are a significant cause of morbidity and mortality, possibly compromised treatment outcomes, and excess healthcare costs. Research in quantifying the risk of neutropenic complications may make it possible in the near future to target patients at greater risk with appropriate preventive strategies, thereby maximizing the benefits and minimizing the costs.

Abstract
STUDY OBJECTIVES To study the impact of filgrastim 5 microg/kg given once/day through absolute neutrophil count (ANC) recovery on the duration of grade 4 neutropenia (ANC < 0.5 x 10(3)/mm3) and time to ANC recovery. Additional objectives were to study the average number of filgrastim injections/cycle required to achieve ANC recovery and differences in outcome by cycle. DESIGN Combined analysis of two double-blind, randomized, multicenter trials. PATIENTS Two hundred twenty-two patients treated for breast cancer. MEASUREMENTS AND MAIN RESULTS All patients but one were evaluable for efficacy end points. Mean +/- SD duration of grade 4 neutropenia was 1.7 +/- 1.3 days in cycle 1; the duration decreased in cycles 2-4 to between 1.0 and 1.2 days. Fifty percent of patients had ANC recovery to 10 x 10(3)/mm3 or greater by day 11 of the cycle, and 90% by day 13, corresponding to 10 and 12 days of filgrastim administration, respectively. Across all cycles, the mean +/- SD number of filgrastim injections/cycle was 10.51 +/- 1.70, with little variation among cycles. CONCLUSION When filgrastim is administered as recommended, starting 24 hours after chemotherapy and continuing through an ANC of 10 x 10(3)/mm3 or greater, neutrophil recovery is rapid and predictable. Because the first cycle of chemotherapy has the highest rates of neutropenia and febrile neutropenia, it seems prudent to administer growth factor support preemptively.

Abstract
The purpose of this study was to clarify the effects of mirimostim (macrophage colony-stimulating factor; M-CSF) on immunological functions after chemotherapy. The percentage of natural killer (NK) cells in peripheral blood mononuclear cells (PBMCs), NK cell activity, T-helper cell 1/T-helper cell 2 (Th1/Th2) ratio, and superoxide anion production by granulocytes (granulocyte function) were measured as immunological parameters before and after chemotherapy in 44 patients with primary ovarian cancer who received at least three consecutive courses of postoperative chemotherapy. Patients were observed during the first course of chemotherapy, and 39 patients who presented grade III or IV neutropenia were entered into this study and randomly allocated to an M-CSF-administered group (group 1; 19 patients) and a non-M-CSF-administered group (group 2; 20 patients) for the second course. For the third course, a crossover trial was conducted. In the observation period, chemotherapy significantly impaired the immunological parameters. In particular, those parameters were significantly decreased at day 14 compared to the level before chemotherapy. The values of the parameters of group 1 were significantly higher than those of group 2. In the course of chemotherapy during which M-CSF was administered, 19 of the 39 patients presented grade IV neutropenia, and received granulocyte colony-stimulating factor (G-CSF) between days 7 and 14. We compared the changes of those immunological parameters in the M-CSF alone group and the M-CSF + G-CSF group, and found that the concomitant use of G-CSF did not further improve the parameters. These results indicate that chemotherapy markedly impaired the immunological functions, and that the administration of M-CSF significantly improved the impaired immunological functions.

Abstract
In hematopoiesis, cytokine levels modulate blood cell replacement, self-renewal of stem cells, and responses to disease. Feedback pathways regulating cytokine levels and targets for therapeutic intervention remain to be determined. Amino boronic dipeptides are orally bioavailable inhibitors of dipeptidyl peptidases. Here we show that the high-affinity inhibitor Val-boro-Pro (PT-100) can stimulate the growth of hematopoietic progenitor cells in vivo and can accelerate neutrophil and erythrocyte regeneration in mouse models of neutropenia and acute anemia. Hematopoietic stimulation by PT-100 correlated with increased cytokine levels in vivo. In vitro, PT-100 promoted the growth of primitive hematopoietic progenitor cells by increasing granulocyte-colony-stimulating factor (G-CSF), interleukin-6 (IL-6), and IL-11 production by bone marrow stromal cells. Two molecular targets of PT-100 are expressed by stromal cells- CD26/DPP-IV and the closely related fibroblast activation protein (FAP). Because PT-100 was active in the absence of CD26, FAP appears to be the hematopoietic target for PT-100. Interaction of PT-100 with the catalytic site seems to be required because amino-terminal acetylation of PT-100 abrogated enzyme inhibition and hematopoietic stimulation. PT-100 is a therapeutic candidate for the treatment of neutropenia and anemia. The data support increasing evidence that dipeptidyl peptidases can regulate complex biologic systems by the proteolysis of signaling peptides.

Abstract
We retrospectively compared the effects of two time points of G-CSF (Filgrastim) introduction for PBSC mobilization in 45 children with different malignancies. Seventeen patients received the first G-CSF dose on day 2 or 3 following chemotherapy (group 1). Twenty-eight patients received a "flexible" G-CSF injection schedule when the G-GSF was started at the time of the first platelet count rise during post-chemotherapy recovery phase (group 2). Leukapheresis was performed when WBC recovery reached >2.0 x 10(9)/l or if the peripheral blood CD34(+) cell level was >0.01 x 10(9)/l. A median of 2 (1-4) leukapheresis procedures was performed in both groups to yield a median of 4.2 and 6.1 x 10(6) CD34(+) cells/kg in groups 1 and 2, respectively, which was generally sufficient for auto-transplantation. The proportion of patients with a failure of PBSC collection was similar and G-CSF consumption estimated through the total cycle dose was 2.3 times less in group 2 without increasing infectious risks. The short-term hematological recovery and the early post-transplant course were similar in the two groups. Delayed introduction of G-CSF after chemotherapy allowed PBSC harvest equivalent to that obtained after early G-CSF introduction. This approach could be an interesting alternative in PBSC mobilization but should be assessed by a prospective controlled study.

Abstract
Event-free survival for children with acute lymphoblastic leukemia (ALL) now exceeds 80% in the most effective trials. Failures are due to relapse, toxicity, and second cancers such as therapy-related myeloid leukemia or myelodysplasia (t-ML). Topoisomerase II inhibitors and alkylators can induce t-ML; additional risk factors for t-ML remain poorly defined. The occurrence of t-ML among children who had received granulocyte colony-stimulating factor (G-CSF) following ALL remission induction therapy prompted us to examine this and other putative risk factors for t-ML in 412 children treated on 2 consecutive ALL protocols from 1991 to 1998. All children received etoposide and anthracyclines, 99 of whom received G-CSF; 284 also received cyclophosphamide, 58 of whom also received cranial irradiation. There were 20 children who developed t-ML at a median of 2.3 years (range, 1.0-6.0 years), including 16 cases of acute myeloid leukemia, 3 myelodysplasia, and 1 chronic myeloid leukemia. Stratifying by protocol, the cumulative incidence functions differed (P =.017) according to the use of G-CSF and irradiation: 6-year cumulative incidence (standard error) of t-ML of 12.3% (5.3%) among the 44 children who received irradiation without G-CSF, 11.0% (3.5%) among the 85 children who received G-CSF but no irradiation, 7.1% (7.2%) among the 14 children who received irradiation plus G-CSF, and 2.7% (1.3%) among the 269 children who received neither irradiation nor G-CSF. Even when children receiving irradiation were excluded, the incidence was still higher in those receiving G-CSF (P =.019). In the setting of intensive antileukemic therapy, short-term use of G-CSF may increase the risk of t-ML.

Abstract
Treatment- and disease-related neutropenia are associated with a number of negative clinical effects such as febrile neutropenia, documented infection, hospitalisation for infection-related morbidity, infection-related mortality, and decreased ability to administer the planned chemotherapy dose on schedule. Reductions or delays in dosage have the ability to jeopardise the effectiveness of treatment by lowering response rates. Not only are clinical outcomes adversely affected, but these complications can have a negative influence on patient quality of life. Filgrastim is a haematopoietic growth factor that primarily acts to stimulate the proliferation and differentiation of neutrophil progenitor cells. Filgrastim is capable of reducing the incidence and severity of neutropenia and the complications that accompany it in patients with cancer or HIV infection. Although there are few data evaluating the effect of treatment with granulocyte colony-stimulating factor on quality of life, it is assumed that the benefits would be seen through both the reduction of treatment-related complications and the enhanced potential for long-term disease control. A new, longer-acting form of filgrastim is now available that has the potential to simplify the management of neutropenia and further improve patient quality of life by decreasing the number of necessary injections. Additional prospective controlled trials that contain quality-of-life issues as endpoints are needed.

Abstract
The prevailing uncertainty about the pharmacoeconomic positioning of granulocyte colony-stimulating factor (G-CSF) in the prevention and treatment of chemotherapy-induced febrile neutropenia has resulted in a number of pharmacoeconomic evaluations published in the past 10 years. These studies vary considerably regarding the approaches used and the results presented. In order to contribute to a clearer pharmacoeconomic positioning of G-CSF, a systematic review of economic evaluations was carried out. The focus of the review was prophylaxis and therapy of chemotherapy-induced neutropenia in patients with cancer. A computerised bibliography search of several databases was conducted yielding 33 studies. The findings demonstrated the cost-saving potential of G-CSF in standard-dose chemotherapy to be limited, with lower costs often seen in the control group. The results of these studies were too heterogeneous to extract a clear recommendation from a cost-saving point of view. The administration of G-CSF after high-dose chemotherapy with stem cell support resulted more often in cost savings in the G-CSF group as compared with standard-dose chemotherapy, illustrating a possible cost-saving potential of G-CSF. In the treatment of established chemotherapy-induced febrile neutropenia, cost savings were found in all studies. This result is surprising but hampered by the small number of studies (n = 5) and remains to be confirmed by more rigourously designed prospective economic analyses. Despite the substantial research on this topic, the economic evaluation of G-CSF is far from being settled and needs further investigation.

Abstract
The administration of G-CSF post transplant has been shown to accelerate the time to neutrophil engraftment. However, this does not necessarily translate into a meaningful clinical benefit to the patient. This randomized study was designed to determine the role of G-CSF following transplantation in patients with breast cancer (BC). A total of 241 evaluable patients with BC were included. There were 200 patients with high-risk BC, and 41 had disseminated BC in complete remission. All patients received conventional dose chemotherapy prior to transplantation. Patients were mobilized with G-CSF, received the STAMP V regimen, were transplanted with > or = 2.5 x 10(6) of CD34(+) cells/kg and were then randomized to receive 5 microg/kg of G-CSF starting on the day of infusion (arm A), five days later (arm B), or no G-CSF (arm C). The need for transfusion support, infectious complications and length of hospitalization were the variables chosen to demonstrate clinical benefit. Patients receiving G-CSF reached 500 and 1000 neutrophils significantly faster (P = 0.001) than patients with no G-CSF. This translated into a significantly (P < 0.05) shorter hospitalization time for patients receiving G-CSF. Arm C was closed and, after recruiting 110 patients in arm A, and 106 in arm B, the significant difference in neutrophil recovery persisted with no difference in the time of hospitalization between arms A and B. Therefore, G-CSF significantly accelerates the time to neutrophil engraftment. This translates into a shorter time of hospitalization. There is no difference in this variable regarding the time of administering the G-CSF: day 0 vs day +5. Therefore, G-CSF on day +5 should be the standard in this setting.

Abstract
To clarify the effect of granulocyte colony-stimulating factor (G-CSF) and macrophage colony-stimulating factor (M-CSF/CSF-1) on chemotherapy-induced infection, we estimated the effect of those CSFs on a mouse model under severe myelosuppression. First, we established an animal model in which 48.9% (22/45) of C3H/Hej mice died of sepsis related to severe myelosuppression after intraperitoneal administration of a single dose (9 mg/kg) of mitomycin C (MMC). G-CSF or M-CSF was administered to this model on various administration schedules after chemotherapy, and the effect of those CSFs on survival rates, peripheral blood granulocyte counts, expression of adhesion molecules (CD11a, CD11b, CD18) on granulocytes and granulocyte function (phagocytosis and superoxide anion production) were examined. In all G-CSF administration groups, peripheral blood granulocyte counts were increased, but improvements in expression of adhesion molecules such as CD11a and CD18, and granulocyte function were less marked and survival rates were not improved. Meanwhile, when M-CSF was administered from 1 to 7 days after chemotherapy, granulocyte and platelet counts were increased, and moreover, expression of adhesion molecules and granulocyte function were markedly improved. Furthermore, the survival rate was significantly improved to 77.8% (28/36) compared with the MMC group (P < 0.05). Positive rate of blood culture examination at 7 days after chemotherapy in the M group was 0%, and was significantly lower than that in the G group (40%) and the MMC group (40%) (P < 0.05). These results demonstrated that it is important not only to increase the granulocyte counts, but also to improve granulocyte functions for preventing infection under myelosuppression after chemotherapy.

Abstract
In an open prospective study with matched historical controls we aimed to evaluate whether a polysaccharide fraction isolated from the herb Echinacea purpurea could counteract the undesired effects of chemotherapy. Fifteen patients with advanced gastric cancer undergoing palliative chemotherapy with etoposide, leucovorin and 5-fluorouracil (ELF) received for 10 days (beginning 3 days before chemotherapy) daily i.v. injections of 2 mg of a polysaccharide fraction isolated from Echinacea purpurea herb cell cultures (EPS-EPO VIIa). The median number of leukocytes 14-16 days after chemotherapy was 3630/microL (range 1470-5770) in the patients receiving EPS-EPO VIIa compared with 2370/microL (870-3950) in the patients of the historical control group (p = 0.015). EPS-EPO VIIa had no clinically relevant effects on phagocytic activity of granulocytes or on lymphocyte subpopulations. Sixty-eight adverse events including two deaths were observed, most likely due to chemotherapy and the general condition of the patients. However, an association with the test intervention cannot be ruled out completely. The results of this pilot study suggest that EPS-EPO VIIa might be effective in reducing chemotherapy-induced leukopenia. The efficacy and safety should be investigated in further studies.

Abstract
Sixty-four untreated adult acute lymphoblastic leukemia (ALL) patients were randomized to receive chemotherapy alone, n = 31 or chemotherapy and granulocyte colony stimulating factor (G-CSF), n = 33. During induction patients received G-CSF for 5 days between four weekly Epirubicin+Vcr administrations, starting 36 h after each application and finishing 48 h before the next one with the intention to possibly generate a cell cycle dependent protection of normal hematopoietic progenitors and to stimulate granulopoiesis. The complete remission (CR) rate equaled 94% in the G-CSF group and 87% in controls. Patients who received G-CSF, if compared to the controls, had shorter granulocytopenia during induction and consolidation, displayed a lower infection rate, completed the induction-consolidation quicker and stayed shorter in hospital during induction, p < 0.001-0.04. Follow-up at 2 years revealed a rather higher probability of survival (59 vs. 27%, p = 0.04) and a lower relapse rate (32 vs. 60%) in G-CSF arm than in controls. The beneficial influence of G-CSF administered in time-sequenced fashion on survival needs further confirmation.

Abstract
To investigate the efficacy and safety of granulocyte colony-stimulating factor (G-CSF) in patients with acute myelogenous leukaemia, a multicentre randomized study was performed. From October 1993 to September 1996, 270 patients with newly diagnosed acute myelogenous leukaemia were randomized to G-CSF or control groups after remission induction therapy. The G-CSF group received G-CSF (Filgrastim) from 48 h after the completing chemotherapy until the absolute neutrophil count exceeded 1.5 x 10(9)/l. The control group did not receive G-CSF unless severe infection occurred. There were 245 evaluable patients (120 and 125 in the G-CSF and control groups respectively). The complete remission rate was similar in the G-CSF and control groups (80.8% versus 76.8%), as was the 5-year probability of disease-free survival (34.5% versus 33.6%) and overall survival (42.7% versus 35.6%). Neutrophil recovery was significantly faster in the G-CSF group than in the control group (12 d versus 18 d, P = 0.0001). The median duration of febrile neutropenia was significantly shorter in the G-CSF group than in the control group (3 d versus 4 d, P = 0.0001). In conclusion, prophylactic administration of G-CSF after remission induction therapy for acute myelogenous leukaemia is safe and useful even in patients without infection on completing chemotherapy.

Abstract
We evaluated the influence of M-CSF treatment on granulocyte functions in patients with ovarian cancer. Eighteen patients with ovarian cancer received two consecutive courses of chemotherapy (16 cases, CAP therapy and two cases, CP therapy) at 4-week intervals. M-CSF (8 million U/day) was infused for 7 days starting from the next day after chemotherapy. Superoxide anion production by isolated peripheral blood granulocytes, their phagocytosis, and expression of cell adhesion molecules such as CD11a, CD11b, and CD18 on granulocytes were measured by flow cytometry. Cytokine (IL-8, G-CSF, and GM-CSF) levels in peripheral blood monocyte (PBM) culture supernatants were measured by enzyme-linked immunosorbent assay in 5 out of 18 cases. The levels of CD11a, CD11b and CD18 expression on peripheral blood granulocytes and superoxide anion production by granulocytes were significantly suppressed by chemotherapy without CSF support. The levels of CD11a and CD18 expression on granulocytes were significantly enhanced by administration of M-CSF. When M-CSF was added to cultured PBM, the level of IL-8 in the supernatant increased with the concentration of M-CSF. When IL-8 was added to cultured granulocytes, the levels of CD18 expression on granulocytes and superoxide anion production by granulocytes were significantly increased. These observations suggest that M-CSF enhances the production of IL-8 from monocytes in vivo, thereby improving chemotherapy-induced granulocyte dysfunction.

Abstract
We carried out a retrospective study on the infection rate--in episodes per 100 person months at risk (p/m/r)--of septicaemia and invasive mycoses in children with solid tumours treated at a single institution between 1985 and 1996. Among 982 patients, accounting for 8108 p/m/r, 257 infectious episodes were documented, for an infection rate of 3.2. The infection rate for "intensive" treatment was greater than that for "less intensive" treatments, 3.7 compared with 0.5, respectively; P<0.001. 58% of infectious episodes were associated with neutropenia, 22% were megatherapy-related, and 39% were related to central venous catheter (CVC), while in 13% of the episodes no risk factor was identified. Of the episodes, single organism Gram-positive bacteraemias accounted for 62%, single organism Gram-negative for 23%, multiple organism bacteraemias for 7%, invasive mycoses for 4%, and isolated fungaemias for 4%. The infection rate for Gram-positive organisms decreased significantly over time (-5.9% per year; P<0.01), but increased for the Gram-negative organisms (+3.4% per year; P=0.4). This study demonstrates that the risk of bacteraemia increases in parallel with the treatment intensity, and that a considerable number of children with solid tumours develop bacteraemia in the absence of an identifiable risk factor.

Abstract
There are very few studies describing the preventive effect of macrophage colony-stimulating factor (M-CSF/CSF-1) on chemotherapy-induced infection. In this study, we evaluated the changes in superoxide anion production by granulocytes before and after chemotherapy in ovarian cancer patients and investigated the preventive effect of M-CSF on chemotherapy-induced febrile neutropenia. Three courses of chemotherapy [paclitaxel 180 mg/m(2) and carboplatin (area under the curve; AUC 5)] were administered to 32 ovarian cancer patients, and seven patients presented febrile neutropenia. In the 25 afebrile patients, the percentage of superoxide anion production by granulocytes was significantly decreased from 86.5 +/- 7.7 (%) to 75.1 +/- 8.8 (%) at day 7 and 71.0 +/- 6.3 (%) at day 14 without administration of CSF. However, in the patients who presented febrile neutropenia, it was more severely decreased from 86.8 +/- 6.8 (%) to 60.0 +/- 9.9 (%) at day 7 and 56.8 +/- 5.0 (%) at day 14 without administration of CSF. When M-CSF was administered to all patients in the next course with the same dose of chemotherapy, the incidence of febrile neutropenia was significantly decreased (P = 0.0195), and the duration of fever (>or= 38.0 degrees C) and high serum C-reactive protein (CRP) (>or= 2.0 mg/dl) were also significantly shortened (P = 0.0023, P = 0.0051). Moreover, in these M-CSF-treated patients, the percentage of superoxide anion production by granulocytes was maintained at the level before chemotherapy. These findings indicate that severe impairment of granulocyte function leads to febrile neutropenia, and that M-CSF reduces the incidence of febrile neutropenia by maintaining or improving granulocyte function.

Abstract
Infection frequently complicates the course of cancer treatment and often adversely affects the outcome. Patients have a greater tendency for acquiring infections caused by opportunistic microorganisms. Agents with low virulence potential may lead to invasive and often life-threatening infections because of altered host immune function. The immune dysfunction may be caused by the underlying malignancy, by antineoplastic chemotherapy, or by invasive procedures during supportive care.

Abstract
PURPOSE We describe the impact of clinical practice guidelines (CPGs) on improvement in oncology treatment processes or outcomes. METHODS We performed a comprehensive search of the literature from 1966 to the present and a directed review of the literature. RESULTS Improvements have been demonstrated in compliance with evidence-based guidelines or evidence-based medicine, and in short-term length of stay, complication rates, and financial outcomes. The data suggest that patient satisfaction can be maintained despite a shorter length of stay. There has been one example of province-wide improvement in disease-free and overall survival of breast cancer patients coincident with the adoption of CPGS: The components of successful guidelines can be summarized as follows: (1) development is based on evidence, with the guideline formulated by key physicians in the group; (2) the guidelines are disseminated to all affected health care professionals for critique; (3) implementation includes direct feedback on performance to physicians or general feedback on system performance; and (4) there is accountability for performance according to the guidelines. This accountability can consist of voluntary peer pressure to conform to evidence-based medicine, and it does not require a financial reward or penalty. CONCLUSION Some attempts to improve practice have been moderately successful in achievement of reduced health care costs, reduced hospital length of stay, and possibly improved outcomes. Other methods that are still in use have been demonstrated to have little effect. Programs that have not succeeded have relied on voluntary change in practice behavior without incentives to change or have had no accountability component. Further research is needed to assess how guidelines are enacted in organizations other than those demonstrably committed to improvement, ways to improve compliance of health care providers who are not committed to change, and methods to improve accountability.

Abstract
Aging is associated with a progressive decline in the functional reserve of multiple organ systems, which may lead to enhanced susceptibility to stress such as that caused by cancer chemotherapy. Myelodepression is the most common and the most commonly fatal complication of antineoplastic drug therapy and may represent a serious hindrance to the management of cancer in older individuals. This is already a common and pervasive problem and promises to become more so. Currently 60% of all neoplasms occur in persons aged 65 years and older, and this percentage is expected to increase as the population ages. This well-known phenomenon, sometimes referred to as squaring or the age pyramid, is caused by the combination of an increasing life expectancy and a decreasing birth rate. This article explores the use of hematopoietic growth factors in the older cancer patient after reviewing the influence of age on hemopoiesis and chemotherapy-related complications. The issue is examined in terms of effectiveness and cost. An outline of the assessment of the older cancer patient is provided at the end of the chapter as a frame of reference for clinical decisions.

Abstract
OBJECTIVE The objective of this study was to better understand neutropenia induced by standard dose chemotherapy and to verify if there are any hematological parameters for defining the phase and possibly the duration of neutropenia. METHODS The kinetics of large unstained cells (LUCs) and lymphocytes was evaluated in 324 blood counts of 56 chemotherapy cycles through the use of a Technicon H2 or an ADVIA 120 hematology analyzer. Blood samples collected during the neutropenia phase were also studied by flow cytometry using a large panel of monoclonal antibodies. Parametric and nonparametric statistics were employed to compare the different variables analyzed. A linear regression between each variable before and after nadir and a simple linear correlation among the same variables in the neutropenic and recovery phase were performed. RESULTS The percentage of LUCs reaches the higher value at nadir and the difference between the mean value of prenadir and nadir is statistically significant (P <.01). The number of LUCs increases during the pre and postnadir phase. Lymphocytes number appears stable in the prenadir phase. The MPXI index increases in the prenadir phase and falls at nadir and this difference is statistically significant(P <.01). LUCs are correlated with blasts and CD34+ cells in the pre and postnadir phase, with CD3+/CD4+ cells in the prenadir phase, and with CD2+/CD56+ in the postnadir phase. CONCLUSIONS Our data have shown that the estimation of both percentage of LUCs and MPXI can predict the neutropenia phase and orient for its duration. The lymphocyte number may be regarded as a parameter of risk of fever after day 5 of chemotherapy and the number of blood CD34+ cells may be predicted by LUC count.

Abstract
Acute myeloid leukaemia (AML) is characterized by a block in differentiation and an unregulated proliferation of myeloid progenitor cells. While the cause of AML in children is unknown, risk factors that have been identified include exposure to toxins such as ethanol, pesticides and dietary topoisomerase II inhibitors, prior chemotherapy with alkylating agents or topoisomerase II inhibitors, constitutional disorders such as Down's syndrome and type I neurofibromatosis, and haematopoietic failure syndromes such as Fanconi anaemia and severe congenital neutropenia. With intensified chemotherapy including high-dose Ara-C, followed in many cases by bone marrow transplantation, and with improvements in supportive care, current survival rates approach 50%. Future advances in paediatric AML will include better risk stratification to determine optimal treatment and targeted cytotoxic therapy.

Abstract
AbstractThe innate immune system provides rapid and effective host defense against microbial invasion in a manner that is independent of prior exposure to a given pathogen.1 It has long been appreciated that the blood contains important elements that mediate rapid responses to infection. Thus, anatomic compartments with ample blood supply are less frequently infected and recover more readily once infected, whereas regions with poor perfusion are prone to severe infection and may require surgical débridement. Blood-borne innate immune mediators are either carried in circulating blood cells (ie, leukocytes and platelets) or in plasma after release from blood cells or on secretion by the liver.
