Abstract
BACKGROUND Febrile neutropenia represents a critical oncologic emergency, and its management is pivotal in cancer therapy. In several guidelines, the use of granulocyte colony-stimulating factor (G-CSF) in patients with chemotherapy-induced febrile neutropenia is not routinely recommended except in high-risk cases. The Japan Society of Clinical Oncology has updated its clinical practice guidelines for the use of G-CSF, incorporating a systematic review to address this clinical question. METHODS The systematic review was conducted by performing a comprehensive literature search across PubMed, the Cochrane Library, and Ichushi-Web, focusing on publications from January 1990 to December 2019. Selected studies included randomized controlled trials (RCTs), non-RCTs, and cohort and case-control studies. Evaluated outcomes included overall survival, infection-related mortality, hospitalization duration, quality of life, and pain. RESULTS The initial search yielded 332 records. Following two rounds of screening, two records were selected for both qualitative and quantitative synthesis including meta-analysis. Regarding infection-related mortality, the event to case ratio was 5:134 (3.73%) in the G-CSF group versus 6:129 (4.65%) in the non-G-CSF group, resulting in a relative risk of 0.83 (95% confidence interval, 0.27-2.58; p = 0.54), which was not statistically significant. Only median values for hospitalization duration were available from the two RCTs, precluding a meta-analysis. For overall survival, quality of life, and pain, no suitable studies were found for analysis, rendering their assessment unfeasible. CONCLUSION A weak recommendation is made that G-CSF treatment not be administered to patients with febrile neutropenia during cancer chemotherapy. G-CSF treatment can be considered for patients at high risk.

Abstract
Background Pegfilgrastim-induced aortitis is a rare but serious adverse event in patients undergoing anticancer therapy with granulocyte colony-stimulating factor analogs. Despite previous case series and systemic reviews, the exact incidence, clinical presentation, and CT manifestations of pegfilgrastim-induced aortitis remain unclear. Purpose To clarify the incidence and clinicoradiologic characteristics of pegfilgrastim-induced aortitis. Materials and Methods Pegfilgrastim administration records from January 2015 to March 2021 were retrospectively collected from the drug prescription database of a single center and were matched with the relevant findings in the CT database. Corresponding CT images within 6 months were available for a total of 1462 doses of pegfilgrastim in 674 patients. Four radiologists reviewed the CT images for the presence of aortitis in two steps. Clinical information and the distribution of aortitis on CT images were examined for patients with a diagnosis of pegfilgrastim-induced aortitis. Results Pegfilgrastim-induced aortitis was observed in 18 of 674 patients (mean age, 62 years ± 13 [SD]; 424 men), resulting in incidence rates of 2.7% per patient (95% CI: 1.6, 4.2) and 1.2% per dose (95% CI: 0.7, 1.9). The most common original primary malignancies were esophageal cancer (n = 10, 9%), breast cancer (n = 3, 4%), and pancreatic cancer (n = 2, 2%). The most common anticancer drugs used at onset were 5-fluorouracil, cisplatin, and docetaxel. Seven cases were symptomatic, while the remaining 11 (61%) were asymptomatic. CT findings indicated that aortitis involved branches of the aortic arch in 13 cases (72%), aortic arch in 10 cases (56%), and abdominal aorta in two cases (11%). Conclusion Pegfilgrastim-induced aortitis may be more prevalent than previously reported and may be more common in patients with esophageal cancer and those who received 5-fluorouracil, cisplatin, and docetaxel as anticancer drugs. The findings also suggest that pegfilgrastim-induced aortitis is often characterized by aortic arch and proximal branch involvement at CT. © RSNA, 2022 Online supplemental material is available for this article.

Cost-Effectiveness Analysis of PEG-rhG-CSF as Primary Prophylaxis to Chemotherapy-Induced Neutropenia in Women With Breast Cancer in China: Results Based on Real-World Data. Front Pharmacol 2022; 12:754366. [PMID: 35185534 PMCID: PMC8850939 DOI: 10.3389/fphar.2021.754366] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2021] [Accepted: 12/30/2021] [Indexed: 12/24/2022] Open
Abstract
Background: Pegylated recombinant human granulocyte colony-stimulating factors (PEG-rhG-CSFs) are more commonly and widely used than recombinant human granulocyte colony-stimulating factors (rhG-CSFs) in preventing chemotherapy-induced neutropenia in patients with stage II-IV breast cancer. To reduce the financial burden on these patients, the corresponding medical insurance directory needs to be revised. Objectives: To evaluate the cost-effectiveness of PEG-rhG-CSF versus rhG-CSF in patients with stage II-IV breast cancer in central China. Methods: Two Markov models, a chemotherapy model and a post-chemotherapy model, were developed to study the effects and costs, with a time horizon of 12 weeks and 35 years, respectively. Cost and probability input data were primarily obtained from a retrospective real-world study conducted in five tertiary hospitals. Propensity score matching was adopted to overcome retrospective bias. Other parameters were extracted from literature as well as advice from clinical experts. Univariate and probabilistic sensitivity analyses were conducted. Results: In the first chemotherapy model, PEG-rhG-CSF was associated with fewer episodes of febrile neutropenia (FN) (N = 19 per 1000 patients treated), infections (N = 24 per 1000 patients treated) and deaths (N = 2 per 1000 patients treated), but higher costs (¥36 more per patient treated). The post-chemotherapy model indicated that PEG-rhG-CSF led to higher gains in quality-adjusted life years (QALYs) (11.695 versus 11.516) in comparison to rhG-CSF. Sensitivity analysis showed that the cost of PEG-rhG-CSF had the greatest impact on the incremental costs, and incremental QALYs were very sensitive to the risk of RDI <85%. The probability of PEG-rhG-CSF being cost-effective compared to rhG-CSF was 66% at the willingness to pay (WTP) thresholds of ¥72,371 per QALY gained. Conclusion: According to this economic evaluation based on real-world data, PEG-rhG-CSF may be considered as a more cost-effective strategy relative to rhG-CSF for stage II-IV breast cancer patients in central China. However, to reflect a national perspective, further evidence is needed using data from larger-scale studies.

Abstract
BACKGROUND Febrile neutropenia (FN) is a life-threatening complication of Docetaxel-based chemotherapy regimens (DBRs). Prophylactic granulocyte-colony stimulating factor (G-CSF) can reduce the risk of FN. This study investigated the effect of G-CSF on FN in patients receiving DBRs for breast cancer. METHODS Patients treated between 2015 and 2017 were identified from the hospital's pharmacy database and their medical records were examined retrospectively. Data from patients' first four cycles of DBR were collected. FN rate, FN associated length of hospital stay (FN-LOS), and chemotherapy dose modification/delay due to FN were compared between patients who did (G-CSF group) or did not (non-GCSF group) receive prophylactic G-CSF. RESULTS Of the 276 included patients, 83.3% received a DBR as adjuvant or neoadjuvant therapy, and 50% received docetaxel as combination therapy. Prophylactic G-CSF was administered with the first cycle of a DBR in 69.9% of patients who were significantly less likely to experience FN compared to the non-G-CSF group (6.2% vs. 15.7%; odds ratio: 0.36 [95% CI: 0.16-0.82]; p = 0.020). Collectively and after the 4 DBR treatment cycles, FN rate (4.8 vs. 8.5; odds ratio: 0.54 [95% CI: 0.30-0.97]; p = 0.043) and the mean FN-LOS (3.55 vs. 5.28 days; t = -2.22; p = 0.037) were reduced in the G-CSF group. There was no difference in DBR dose delay/reduction between both groups in cycles 2-4. CONCLUSION In patients receiving DBRs for breast cancer, prophylactic G-CSF significantly reduced both the rate of FN and duration of hospitalization for FN.

Continuous Intravenous Administration of Granulocyte-Colony-Stimulating Factors-A Breakthrough in the Treatment of Cancer Patients with Febrile Neutropenia. ACTA ACUST UNITED AC 2021; 57:medicina57070675. [PMID: 34208815 PMCID: PMC8305666 DOI: 10.3390/medicina57070675] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2021] [Revised: 05/17/2021] [Accepted: 06/21/2021] [Indexed: 11/16/2022]
Abstract
Background: Febrile neutropenia (FN) remains one of the most challenging problems in medical oncology and is a very severe side effect of chemotherapy. Its late consequences, when it is recurrent or of a severe grade, are dose reduction and therapy delays. Current guidelines allow the administration of granulocyte-colony-stimulating factors (G-CSF) for profound FN (except for the case when a pegylated form of G-CSF is administrated with prophylactic intention) in addition to antibiotics and supportive care. Methods: This is a prospective study that included 96 patients with confirmed malignancy, treated with chemotherapy, who developed FN during their oncological therapy, and were hospitalized. They received standard treatment plus a dose of G-CSF of 16 µg/Kg/day IV continuous infusion. Results: The gender distribution was almost symmetrical: Male patients made up 48.96% and 51.04% were female patients, with no significance on recovery from FN (p = 1.00). The patients who received prophylactic G-CSF made up 20.21%, but this was not a predictive or prognostic factor for the recovery time from aplasia (p = 0.34). The median chemotherapy line where patients with FN were included was two and the number of previous chemotherapy cycles before FN was three. The median serological number of neutrophils (PMN) was 450/mm3 and leucocytes (WBC) 1875/mm3 at the time of FN. Ten patients possess PMN less than 100/mm3. The median time to recovery was 25.5 h for 96 included patients, with one failure in which the patient possessed grade 5 FN. Predictive factors for shorter recovery time were lower levels of C reactive protein (p < 0.001) and procalcitonin (p = 0.002) upon hospital admission and higher WBC (p = 0.006) and PMN (p < 0.001) at the time of the provoking cycle of chemotherapy for FN. The best chance for a shorter duration of FN was a short history of chemotherapy regarding the number of cycles) (p < 0.0001). Conclusions: Continuous IV administration of G-CSF could be an alternative salvage treatment for patients with profound febrile neutropenia, with a very fast recovery time for neutrophiles.

Osteocytes regulate neutrophil development through IL-19: a potent cytokine for neutropenia treatment. Blood 2021; 137:3533-3547.

Abstract
Osteocytes are the most abundant (90% to 95%) cells in bone and have emerged as an important regulator of hematopoiesis, but their role in neutrophil development and the underlying mechanisms remain unclear. Interleukin 19 (IL-19) produced predominantly by osteocytes stimulated granulopoiesis and neutrophil formation, which stimulated IL-19 receptor (IL-20Rβ)/Stat3 signaling in neutrophil progenitors to promote their expansion and neutrophil formation. Mice with constitutive activation of mechanistic target of rapamycin complex (mTORC1) signaling in osteocytes (Dmp1-Cre) exhibited a dramatic increase in IL-19 production and promyelocyte/myelocytic expansion, whereas mTORC1 inactivation in osteocytes reduced IL-19 production and neutrophil numbers in mice. We showed that IL-19 administration stimulated neutrophil development, whereas neutralizing endogenous IL-19 or depletion of its receptor inhibited the process. Importantly, low-dose IL-19 reversed chemotherapy, irradiation, or chloramphenicol-induced neutropenia in mice more efficiently than granulocyte colony-stimulating factor. This evidence indicated that IL-19 was an essential regulator of neutrophil development and a potent cytokine for neutropenia treatment.

Abstract
Human granulocyte colony-stimulating factor (G-CSF, this study used Fc-fused recombinant G-CSF; GX-G3) is an important glycoprotein that stimulates the proliferation of granulocytes and white blood cells. Thus, G-CSF treatment has been considered as a crucial regimen to accelerate recovery from chemotherapy-induced neutropenia in cancer patients suffering from non-myeloid malignancy or acute myeloid leukemia. Despite the therapeutic advantages of G-CSF treatment, an assessment of its immunogenicity must be performed to determine whether the production of anti-G-CSF antibodies causes immune-related disorders. We optimized and validated analytical tools by adopting validation parameters for immunogenicity assessment. Using these validated tools, we analyzed serum samples from rats and monkeys injected subcutaneously with GX-G3 (1, 3 or 10 mg/kg once a week for 4 weeks followed by a 4-week recovery period) to determine immunogenicity response and toxicokinetic parameters with serum concentration of GX-G3. Several rats and monkeys were determined to be positive for anti-GX-G3 antibodies. Moreover, the immunogenicity response of GX-G3 was lower in monkeys than in rats, which was relevant to show less inhibition of toxicokinetic profiles in monkeys, at least 1 mg/kg administrated group, compared to rats. These results suggested the establishment and validation for analyzing anti-GX-G3 antibodies and measurement of serum levels of GX-G3 and anti-GX-G3 antibodies, which was related with toxicokinetic profiles. Taken together, this study provides immunogenicity assessment which is closely implicated with toxicokinetic study of GX-G3 in 4-week repeated administrated toxicological studies.

Abstract
Cancer care has been profoundly impacted by the global pandemic of severe acute respiratory syndrome coronavirus 2 disease (coronavirus disease 2019, COVID-19), resulting in unprecedented challenges. Supportive care is an essential component of cancer treatment, seeking to prevent and manage chemotherapy complications such as febrile neutropenia, anaemia, thrombocytopenia/bleeding, thromboembolic events and nausea/vomiting, all of which are common causes of hospitalisation. These adverse events are an essential consideration under routine patient management, but particularly so during a pandemic, a setting in which clinicians aim to minimise patients' risk of infection and need for hospital visits. Professional medical oncology societies have been providing updated guidelines to support health care professionals with the management, treatment and supportive care needs of their patients with cancer under the threat of COVID-19. This paper aims to review the recommendations made by the most prominent medical oncology societies for devising and modifying supportive care strategies during the pandemic.

Abstract
Abstract
Biologics are significant drivers of globally escalating healthcare costs. Biosimilars have potential to offer cost savings with comparable efficacy and safety to innovator products and increase the access of treatment to more patients. This study aimed to increase understanding and perception of biosimilars concept. It also described the pharmacoeconomic impact of biosimilar in oncology and formulary consideration of oncology biosimilars substituting with their originators in major oncology centers in the Saudi Arabia. A biosimilar is a biological product that is similar to a reference biopharmaceutical product. As the manufacturing process hinders the ability to identically replicate the structure of the original product, biosimilar cannot be described as an absolute equivalent of the original medication. Different regulatory agencies such as United States Food and Drug Administration, European Medicines Agency, and Saudi Food and Drug Authority have approved several biosimilars of oncology biologics. The experience of biosimilar use in Europe and USA provides valuable insights into the use of biosimilars. The widespread use of biosimilars has the potential to reduce healthcare expenditure, as well as improving access without compromising patient outcomes. There is a need for increasing awareness about biosimilars to improve acceptance rates. The use of biosimilar filgrastim in Ministry of National Guard Health Affairs, Saudi Arabia, has resulted in a significant cost saving annually. It was proposed that further substitution and switching to biosimilars in oncology would lead to major savings in resources.

Abstract
The production of the recombinant proteins under the control of AOX1 promoter is a one of the most common expression systems in the methylotrophic yeast Pichia pastoris which is induced by methanol. The application of this expression platform is restricted by the toxicity and inflammatory nature of methanol, especially in food and pharmaceutical products. Human granulocyte macrophage-colony stimulating factor (hGM-CSF) is an important pharmaceutical protein, playing a crucial role in the proliferation and differentiation of innate immune cells. In this study, a methanol-free expression platform for extracellular expression of hGM-CSF was developed. To attain this goal, a novel constructed expression vector pEP(α)101, carrying the FMD promoter regulating recombinant expression by glycerol derepression was designed. The optimized hGM-CSF gene was subcloned into pEP(α)101 and transformed into P. pastoris. The expression of rhGM-CSF in three different culture media were investigated. Based on the observed heterogeneous glycosylation pattern on SDS-PAGE and western blot, the glycoproteins were deglycosylated to remove carbohydrate units. According to the results, the novel methanol independent PFMD expression platform would be a suitable candidate for driving heterologous gene expression especially for the production of food-grade and therapeutically important recombinant proteins.

Abstract
Neutrophils form an essential part of innate immunity against infection. Cancer chemotherapy-induced neutropenia (CCIN) is a condition in which the number of neutrophils in a patient's bloodstream is decreased, leading to increased susceptibility to infection. Granulocyte colony-stimulating factor (GCSF) has been the only approved treatment for CCIN over two decades. To date, CCIN-related infection and mortality remain a significant concern, as neutrophils generated in response to administered GCSF are functionally immature and cannot effectively fight infection. This review summarizes the molecular regulatory mechanisms of neutrophil granulocytic differentiation and innate immunity development, dissects the biology of GCSF in myeloid expansion, highlights the shortcomings of GCSF in CCIN treatment, updates the recent advance of a selective retinoid agonist that promotes neutrophil granulocytic differentiation, and evaluates the benefits of developing GCSF biosimilars to increase access to GCSF biologics versus seeking a new mode to fundamentally advance GCSF therapy for treatment of CCIN.

Abstract
Cytotoxic chemotherapy is the standard treatment for patients with advanced bladder cancer. However, this treatment can cause transient and prolonged neutropenia, which can result in fatal infection. Three recombinant human colony‑stimulating factors (CSFs), granulocyte CSF (G‑CSF), granulocyte‑macrophage CSF (GM‑CSF), and macrophage CSF (M‑CSF), are currently available to reduce the duration and degree of neutropenia. The present study investigated the pro‑ and anti‑tumor effects of these three CSFs and the changes in molecular profiles. Xenograft tumors in athymic mice were generated by subcutaneously inoculating the human bladder cancer cell lines MGH‑U3 and UM‑UC‑3. A total of 2 weeks after cell inoculation, mice were randomly divided into four groups (control, G‑CSF, GM‑CSF and M‑CSF) and treated thrice a week for 2 weeks. Tumor growth during monitoring and tumor weight at the time of euthanization were significantly higher in mice treated with G‑CSF and lower in mice treated with GM‑CSF compared with the control mice. Tumors were examined by immunostaining with antibodies against proteins associated tumor proliferation (Ki‑67), angiogenesis [CD31 and vascular endothelial growth factor (VEGF)], anti‑immunity (CD204) and epithelial‑mesenchymal transition (EMT; E‑cadherin). Immunohistochemical staining revealed that tumor proliferation, angiogenesis, recruitment of M2 macrophages and EMT were promoted by G‑CSF, whereas lymphangiogenesis and recruitment of M2 macrophages were inhibited by GM‑CSF. Treatment‑associated changes in serum pro‑ and anti‑tumoral cytokines and chemokines were evaluated by enzyme‑linked immunosorbent assay (ELISA)‑based arrays. In the ELISA for serum, the levels of cytokines associated with angiogenesis (interleukin‑6 and VEGF), and EMT (transforming growth factor‑β1 and ‑β2) were elevated in mice treated with G‑CSF. Treatment with GM‑CSF and M‑CSF also affected the level of these cytokines characteristically. The current results indicate that administration of exogenous G‑CSF to patients with bladder cancer promotes tumor growth through promotion of cell proliferation, angiogenesis, recruitment of M2 macrophages and enhancement of EMT through the modulation of the tumor microenvironment.

Abstract
Febrile neutropenia (FN) is a common dose-limiting toxicity of chemotherapy, with a profound impact on the evolution of patients with cancer, due to the potential development of serious complications, mortality, delays, and decrease in treatment intensity. This article seeks to present an updated clinical guideline, with recommendations regarding the diagnosis, prevention, and treatment of febrile neutropenia in adults with solid tumors. The aspects covered include how to properly approach the risk of microbial resistances, epidemiological aspects, considerations about the initial empirical approach adapted to the risk, special situations, and prevention of complications. A decision-making algorithm is included for use in the emergency department based on a new, validated tool, the Clinical Index of Stable Febrile Neutropenia, which can be used in patients with solid tumors who appear stable in the initial phase of neutropenic infections, and can help detect those at high risk for complications in whom early discharge must be avoided.

Abstract
OBJECTIVES To examine the cost-effectiveness of lipegfilgrastim versus pegfilgrastim as primary prophylaxis in women with early stage breast cancer. METHODS Two Markov models including a chemotherapy and a post-chemotherapy models were constructed with a time horizon of 12 weeks and 30 years, respectively. All the transition probabilities and utility weights were derived from clinical trials and/or published literatures. The costs populated in the chemotherapy model were extracted from Medicare, Pharmaceutical Benefit Scheme and the Independent Hospital Pricing Authority. No cost was considered in the post-chemotherapy model. Sensitivity analyses were performed to test the robustness of the results. RESULTS From the first chemotherapy model, lipegfilgrastim was associated with fewer episodes of severe neutropenia (SN) (N = 142 per 1000 patients treated), febrile neutropenia (FN) (N = 29 per 1000 patients treated), infection (N = 17 per 1000 patients treated) and chemotherapy delayed (N = 170 per 1000 patients treated) and lower cost ($116.88 less per patient treated). The post-chemotherapy model indicated lipegfilgrastim led to higher gains in both life years (18.72 versus 18.61) and quality-adjusted life years (17.28 versus 17.18) in comparison to pegfilgrastim. Sensitivity analysis showed that the results from the chemotherapy model is very sensitive to the baseline risk of SN; while from the probabilistic sensitivity analysis, lipegfilgrastim was likely to be more cost-effective than pegfilgrastim based on two models. CONCLUSIONS Lipegfilgrastim was likely to be a cost-effective alternative to pegfilgrastim as primary prophylaxis. The sensitivity analysis showed the confidence interval for the cost and benefit outcomes overlapped to a great extent, suggesting an insignificant difference.

Abstract
Aims and background Febrile neutropenia (FN) is a major complication of chemotherapy and is associated with substantial morbidity, mortality and costs. The aim of this study was to evaluate the cost-effectiveness of primary prophylaxis with pegfilgrastim versus six-day filgrastim in preventing FN in Italian patients with early-stage breast cancer receiving adjuvant chemotherapy associated with a ≥20% FN risk. Methods The pharmacoeconomic evaluation was based on a decision-analytic model taking into account the possible consequences of FN (e.g., death and reduction/delay of chemotherapy dose). Parameters included in the model were relative risk of FN with pegfilgrastim versus six-day filgrastim; direct costs (drug purchase and FN-related hospitalizations); relative risk of relative dose intensity <85% with pegfilgrastim versus filgrastim; impact on long-term survival due to relative dose intensity <85%; and impact of age on FN and relative dose intensity <85%. Results Under base-case assumptions, pegfilgrastim was cost-effective compared to six-day filgrastim in Italy. The estimated cost, life expectancy and quality-adjusted life years per person for pegfilgrastim were € 3078, 16.47 years, and 15.32; the corresponding figures for six-day filgrastim were € 3033, 16.35 years, and 15.22. The corresponding incremental cost-effectiveness ratio with pegfilgrastim was € 409 per life-year gained and € 429 per quality-adjusted life year gained. One-way sensitivity analyses showed that the results were most sensitive to the relative risk of FN for 6-day filgrastim versus pegfilgrastim. The results were moderately sensitive to the cost of pegfilgrastim and filgrastim, cost of drug administration, cost of FN hospitalization, and number of chemotherapy cycles. Pegfilgrastim remained cost-effective, with an incremental cost-effectiveness ratio well below the accepted limit of € 50,000 per life year gained in all one-way sensitivity analyses. A two-way sensitivity analysis on cost of drugs showed a range of pegfilgrastim dominance over six-day filgrastim. Conclusions At the current official price in Italy, primary prophylaxis with pegfilgrastim improved health outcomes with a very limited cost increase for the National Health Service payer. Even when very low prices of filgrastim and high prices of pegfilgrastim were considered in the model, the resulting incremental cost-effectiveness ratio remained well within the acceptable cost-effectiveness limit of € 50,000/quality-adjusted life year.

Abstract
Cancer care has become increasingly specialized and advances in therapy have resulted in a larger number of patients receiving care. There has been a significant increase in the number of patients presenting with cancer related emergencies including treatment toxicities and those directly related to the malignancy. Suspected neutropenic sepsis is an acute medical emergency and empirical antibiotic therapy should be administered immediately. The goal of empirical therapy is to cover the most likely pathogens that will cause life-threatening infections in neutropenic patients. Patients with febrile neutropenia are a heterogeneous group with only a minority of treated patients developing significant medical complications. Outpatient management of low risk febrile neutropenia patients identified by the MASCC score is a safe and effective strategy. Immunotherapy with "checkpoint inhibitors" has significantly improved outcomes for patients with metastatic melanoma and evidence of benefit in a wide range of malignancies is developing. Despite these clinical benefits a number of immune related adverse events have been recognised which can affect virtually all organ systems and are potentially fatal. The timing of the onset of the adverse events is dependent on the organ system affected and unlike anti-neoplastic therapy can be delayed significantly after initiation or completion of therapy. The field of Acute Oncology is changing rapidly. Alongside, the traditional challenge of neutropenic sepsis there are many emerging toxicities. Further research into the optimal management, strategies and pathways of acutely unwell patients with cancer is required.

Abstract
Fever during chemotherapy-induced neutropenia continues to be a major cause of morbidity and mortality in cancer patients. Mortality depends on the duration and degree of neutropenia, bacteremia, sepsis, performance status, comorbidities and other parameters. The highest mortality rates in cancer patients hospitalized with febrile neutropenia (FN) are observed in those with documented infection. The objectives of the study were to present available tools for risk assessment, to review pathogens causing infections in adult FN patients and to assess outcomes.

Abstract
The purpose of this study was to propose a time-series modeling and simulation (M&S) strategy for probabilistic cost-effective analysis in cancer chemotherapy using a Monte-Carlo method based on data available from the literature. The simulation included the cost for chemotherapy, for pharmaceutical care for adverse events (AEs) and other medical costs. As an application example, we describe the analysis for the comparison of four regimens, cisplatin plus irinotecan, carboplatin plus paclitaxel, cisplatin plus gemcitabine (GP), and cisplatin plus vinorelbine, for advanced non-small cell lung cancer. The factors, drug efficacy explained by overall survival or time to treatment failure, frequency and severity of AEs, utility value of AEs to determine QOL, the drugs' and other medical costs in Japan, were included in the model. The simulation was performed and quality adjusted life years (QALY) and incremental cost-effectiveness ratios (ICER) were calculated. An index, percentage of superiority (%SUP) which is the rate of the increased cost vs. QALY-gained plots within the area of positive QALY-gained and also below some threshold values of the ICER, was calculated as functions of threshold values of the ICER. An M&S process was developed, and for the simulation example, the GP regimen was the most cost-effective, in case of threshold values of the ICER=$70000/year, the %SUP for the GP are more than 50%. We developed an M&S process for probabilistic cost-effective analysis, this method would be useful for decision-making in choosing a cancer chemotherapy regimen in terms of pharmacoeconomic.

Abstract
Objective. To report a case where both pegfilgrastim and filgrastim were considered in the treatment of febrile neutropenia in a hospitalized patient and assess the most cost-effective option. Case summary. A 77-year-old white female was diagnosed with squamous cell carcinoma of the anus and adjuvant chemotherapy was ordered. She subsequently developed Grade 4 neutropenia, a wound infection and her Eastern Cooperative Oncology Group (ECOG) performance status declined to 4. Antibiotics were started and growth factor therapy was considered as part of her treatment. Filgrastim 480 g subcutaneously every day was chosen and her absolute neutrophil count (ANC) recovered after seven days of therapy. Discussion. This case illustrates the potential cost benefits of using filgrastim over pegfilgrastim in hospitalized patients. The choice of filgrastim in our patient resulted in only seven days of filgrastim therapy at a cost of $2205.70. A 6 mg dose of pegfilgrastim is priced similarly to 10 days of filgrastim 480 g, therefore a cost savings of $744.01 was realized in our patient. Conclusions. Filgrastim is the most appropriate growth factor for the treatment of established high-risk febrile neutropenia given that the ANC can be monitored on a daily basis and therapy can be discontinued upon recovery.

Abstract
Febrile neutropenia is common chemotherapy complication significantly impacting patient’s outcomes, quality of life and costs, too. Febrile neutropenia (FN) often leads to hospitalization, the need for intravenous antibiotics and use of granulocyte colony-stimulating factors (GCSF) in order to avoid its complications. Cost of febrile neutropenia is well described in literature, but no study has been performed in Bosnia and Herzegovina. We have conducted observational cohort study with aim to describe and present costs of FN treatment from payers’ (provider’s) perspective. Only direct medical costs from one middle-sized oncology Clinic in Bosnia and Herzegovina database have been included and presented. We found that overall cost in five months period (January-May 2015) were almost 30.000 euros, or 1.0035 euro per episode/patient in average. The highest cost are allocated to hospitalization (40%), followed by GCSF (36%), while rest of costs are generated by laboratory tests performed and drug application. Proportion of costs is in line with other published studies even with huge differences in absolute values, mainly to low prices of services in Bosnia and Herzegovina. This was the first study on costs of chemotherapy induced FN in Bosnia and Herzegovina suggesting that significant costs are inquired by this conditions and that further research should be performed including larger patient population and other clinical oncology data, including pharmacoeconomic analysis.

Enhanced and Secretory Expression of Human Granulocyte Colony Stimulating Factor by Bacillus subtilis SCK6. BIOMED RESEARCH INTERNATIONAL 2016; 2015:636249. [PMID: 26881203 PMCID: PMC4735991 DOI: 10.1155/2015/636249] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/02/2015] [Revised: 12/08/2015] [Accepted: 12/08/2015] [Indexed: 11/18/2022]
Abstract
This study describes a simplified approach for enhanced expression and secretion of a pharmaceutically important human cytokine, that is, granulocyte colony stimulating factor (GCSF), in the culture supernatant of Bacillus subtilis SCK6 cells. Codon optimized GCSF and pNWPH vector containing SpymwC signal sequence were amplified by prolonged overlap extension PCR to generate multimeric plasmid DNA, which was used directly to transform B. subtilis SCK6 supercompetent cells. Expression of GCSF was monitored in the culture supernatant for 120 hours. The highest expression, which corresponded to 17% of the total secretory protein, was observed at 72 hours of growth. Following ammonium sulphate precipitation, GCSF was purified to near homogeneity by fast protein liquid chromatography on a QFF anion exchange column. Circular dichroism spectroscopic analysis showed that the secondary structure contents of the purified GCSF are similar to the commercially available GCSF. Biological activity, as revealed by the regeneration of neutrophils in mice treated with ifosfamine, was also similar to the commercial preparation of GCSF. This, to our knowledge, is the first study that reports secretory expression of human GCSF in B. subtilis SCK6 with final recovery of up to 96 mg/L of the culture supernatant, without involvement of any chemical inducer.

Risk factors for mortality despite early protocolized resuscitation for severe sepsis and septic shock in the emergency department. J Crit Care 2015; 31:13-20. [PMID: 26611382 DOI: 10.1016/j.jcrc.2015.10.015] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2015] [Revised: 10/03/2015] [Accepted: 10/17/2015] [Indexed: 01/28/2023]
Abstract
PURPOSE The purpose was to identify risk factors associated with in-hospital mortality among emergency department (ED) patients with severe sepsis and septic shock managed with early protocolized resuscitation. METHODS This was a retrospective, observational cohort study in an academic, tertiary care ED. We enrolled 411 adult patients with severe sepsis and lactate ≥4.0 mmol/L (n = 203) or septic shock (n = 208) who received protocolized resuscitation from 2005 to 2009. Emergency department variables, microbial cultures, and in-hospital outcomes were obtained from the medical record. Multivariable regression was used to identify factors independently associated with in-hospital mortality. RESULTS Mean age was 59.5 ± 16.3 years; 57% were male. Mean lactate was 4.8 mmol/L (3.5-6.7), 54% had positive cultures, and 27% received vasopressors in the ED. One hundred and five (26%) patients died in-hospital. Age, active cancer, do-not-resuscitate status on ED arrival, lack of fever, hypoglycemia, and intubation were independently associated with increased in-hospital mortality. Lactate clearance and diabetes were associated with a decreased risk of in-hospital death. CONCLUSIONS We identified a number of factors that were associated with in-hospital mortality among ED patients with severe sepsis or septic shock despite treatment with early protocolized resuscitation. These findings provide insights into aspects of early sepsis care that can be targets for future intervention.

Abstract
Background This analysis was undertaken to evaluate the practice patterns of Japanese physicians regarding curative-intent chemotherapy, especially in outpatient settings, and to define factors negatively affecting the maintenance of relative dose intensity (RDI). Methods We performed a web-based questionnaire survey of Japanese physicians involved in malignant lymphoma chemotherapy (Group ML) or in breast cancer chemotherapy (Group BC). The questionnaire inquired how they manage low-risk febrile neutropenia (FN) caused by initial chemotherapy for diffuse large B-cell lymphoma(DLBCL) or by adjuvant chemotherapy for breast cancer in an outpatient setting. Results Valid responses were obtained from 185 physicians in Group ML and 160 in Group BC. In Group ML, 76 % (n = 141) of the physicians were board-certified hematologists, while 82 % (n = 131) of the physicians in Group BC were board-certified surgeons. A significantly higher proportion of physicians in Group ML responded that “dose reduction is not required for the subsequent course of chemotherapy after the first episode of FN” than in Group BC (ML versus BC; 77 % versus 31 %; P < 0.001). Significantly higher proportions of physicians in Group ML were more likely to prophylactically administer antibiotics or granulocyte-colony stimulating factor (G-CSF; ML versus BC; antibiotics: 36 % versus 26 %, P = 0.049; G-CSF: 25 % versus 16 %, P = 0.047). Eighty six percent (n = 159) of Group ML and 70 % (n = 112) of Group BC responded that “emergency outpatient unit is open at all hours”. Conclusions Japanese physicians are more likely to administer reduced doses of chemotherapy to patients with breast cancer than to patients with malignant lymphoma. Supportive infrastructures should be improved to ensure the provision of adequate chemotherapy to all cancer patients.

Abstract
Febrile neutropenia (FN) is one of the most common adverse events associated with myelosuppressive chemotherapy for cancer treatment. The objective of this study was to describe the incidence of hospitalization due to FN in Spanish tertiary care hospitals (PINNACLE study). This epidemiological, retrospective, multicenter, nationwide study involved 119 patients from oncology units of 10 Spanish tertiary care hospitals who were admitted for FN. The primary endpoint was to assess the epidemiology and characteristics of FN. The incidence of admissions due to FN in oncology patients was 2.0% (interquartile range [IQR], 1.6-3.0). In terms of fever and absolute neutrophil count (ANC), 37.0% of the patients had a temperature of ≥38.2°C and an ANC of ≤500/m3. The number of patients who received prophylactic treatment with granulocyte colony-stimulating factor (G-CSF) was significantly higher in the palliative group (32.6%) compared with that in the non-palliative group (13.5%). The hospital length of stay was significantly shorter in patients who received prophylactic G-CSF compared with those who did not (5.0 days; IQR, 4.0-9.0 vs. 7.0 days; IQR, 5.0-11.0, respectively). The hospital length of stay was also significantly shorter in patients receiving palliative treatment (5.0 days; IQR, 3.0-7.0) compared with those receiving non-palliative therapy (7.0 days; IQR, 5.0-12.0). In conclusion, the incidence of admissions due to FN in oncology patients was 2.0% and the duration of hospital stay was 7.0 days. Prophylactic G-CSF treatment was found to be associated with better outcomes and shorter hospital stays. Therefore, the use of this treatment becomes relevant for achieving better clinical outcomes and reducing hospitalization cost in the management of FN.

Abstract
Background Although the growth-factor G-CSF is widely used to prevent granulotoxic side effects of cytotoxic chemotherapies, its optimal use is still unknown since treatment outcome depends on many parameters such as dosing and timing of chemotherapies, pharmaceutical derivative of G-CSF used and individual risk factors. We showed in the past that a pharmacokinetic and –dynamic model of G-CSF and human granulopoiesis can be used to predict the performance of yet untested G-CSF schedules. However, only a single chemotherapy was considered so far. In the present paper, we propose a comprehensive model of chemotherapy toxicity and combine it with our cell kinetic model of granulopoiesis. Major assumptions are: proportionality of cell numbers and cell loss, delayed action of chemotherapy, drug, drug-dose and cell stage specific toxicities, no interaction of drugs and higher toxicity of drugs at the first time of application. Correspondingly, chemotherapies can be characterized by a set of toxicity parameters which can be estimated by fitting the predictions of our model to clinical time series data of patients under therapy. Data were either extracted from the literature or were received from cooperating clinical study groups. Results Model assumptions proved to be feasible in explaining granulotoxicity of 10 different chemotherapeutic drugs or drug-combinations applied in 33 different schedules with and without G-CSF. Risk groups of granulotoxicity were traced back to differences in toxicity parameters. Conclusion We established a comprehensive model of combined G-CSF and chemotherapy action in humans which allows us to predict and compare the outcome of alternative G-CSF schedules. We aim to apply the model in different clinical contexts to optimize and individualize G-CSF treatment.

Abstract
BACKGROUND Febrile neutropenia is a frequent adverse event experienced by people with cancer who are undergoing chemotherapy, and is a potentially life-threatening situation. The current treatment is supportive care plus antibiotics. Colony-stimulating factors (CSFs), such as granulocyte-CSF (G-CSF) and granulocyte-macrophage CSF (GM-CSF), are cytokines that stimulate and accelerate the production of one or more cell lines in the bone marrow. Clinical trials have addressed the question of whether the addition of a CSF to antibiotics could improve outcomes in individuals diagnosed with febrile neutropenia. However, the results of these trials are conflicting. OBJECTIVES To evaluate the safety and efficacy of adding G-CSF or GM-CSF to standard treatment (antibiotics) when treating chemotherapy-induced febrile neutropenia in individuals diagnosed with cancer. SEARCH METHODS We conducted the search in March 2014 and covered the major electronic databases: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, LILACS, and SCI. We contacted experts in hematology and oncology and also scanned the citations from the relevant articles. SELECTION CRITERIA We searched for randomized controlled trials (RCTs) that compared CSF plus antibiotics versus antibiotics alone for the treatment of chemotherapy-induced febrile neutropenia in adults and children. DATA COLLECTION AND ANALYSIS We used the standard methodological procedures expected by The Cochrane Collaboration. We performed meta-analysis of the selected studies using Review Manager 5 software. MAIN RESULTS Fourteen RCTs (15 comparisons) including a total of 1553 participants addressing the role of CSF plus antibiotics in febrile neutropenia were included. Overall mortality was not improved by the use of CSF plus antibiotics versus antibiotics alone (hazard ratio (HR) 0.74 (95% confidence interval (CI) 0.47 to 1.16) P = 0.19; 13 RCTs; 1335 participants; low quality evidence). A similar finding was seen for infection-related mortality (HR 0.75 (95% CI 0.47 to 1.20) P = 0.23; 10 RCTs; 897 participants; low quality evidence). Individuals who received CSF plus antibiotics were less likely to be hospitalized for more than 10 days (risk ratio (RR) 0.65 (95% CI 0.44 to 0.95) P = 0.03; 8 RCTs; 1221 participants; low quality evidence) and had more number of participants with a more faster neutrophil recovery (RR 0.52 (95% CI 0.34 to 0.81) P = 0.004; 5 RCTs; 794 participants; moderate quality evidence) than those treated with antibiotics alone. Similarly, participants receiving CSF plus antibiotics had shorter duration of neutropenia (standardized mean difference (SMD) -1.70 (95% CI -2.65 to -0.76) P = 0.0004; 9 RCTs; 1135 participants; moderate quality evidence), faster recovery from fever (SMD -0.49 (95% CI -0.90 to -0.09) P value = 0.02; 9 RCTs; 966 participants; moderate quality evidence) and shorter duration of antibiotics use (SMD -1.50 (95% CI -2.83 to -0.18) P = 0.03; 3 RCTs; 457 participants; low quality evidence) compared with participants receiving antibiotics alone. We found no significant difference in the incidence of deep venous thromboembolism (RR 1.68 (95% CI 0.72 to 3.93) P = 0.23; 4 RCTs; 389 participants; low quality evidence) in individuals treated with CSF plus antibiotics compared with those treated with antibiotics alone. We found higher incidence of bone or joint pain or flu-like symptoms (RR 1.59 (95% CI 1.04 to 2.42) P = 0.03; 6 RCTs; 622 participants; low quality evidence) in individuals treated with CSF plus antibiotics compared with those treated with antibiotics alone. Overall, the methodological quality of studies was moderate to low across different outcomes. The main reasons to downgrade the quality of evidence were inconsistency across the included studies and imprecision of results. AUTHORS' CONCLUSIONS The use of a CSF plus antibiotics in individuals with chemotherapy-induced febrile neutropenia had no effect on overall mortality, but reduced the amount of time participants spent in hospital and improved their ability to achieve neutrophil recovery. It was not clear whether CSF plus antibiotics had an effect on infection-related mortality. Participants receiving CSFs had shorter duration of neutropenia, faster recovery from fever and shorter duration of antibiotics use.

Abstract
INTRODUCTION In the USA, neutropenia-related hospitalization is estimated to occur in 34.2 cases per 1,000 chemotherapy-treated patients. The cost of hospitalization is significant with estimates ranging, on average, from $10,000 to $30,000 per neutropenia-related hospitalization. Prophylactic use of granulocyte colony-stimulating factor (G-CSF) significantly reduces the risk and duration of neutropenia-related negative events. However, the exact economic benefits of using G-CSF prophylactically are not completely known. The objective of this review is to examine the cost of G-CSF as primary prophylaxis (PP) as well as when used reactively to treat severe neutropenia (SN) or febrile neutropenia (FN). METHODS Electronic databases were searched for studies published up to January 2014. RESULTS The evidence supporting the cost-effectiveness of PP use of G-CSF is inconsistent. The cost savings of PP use of G-CSF associated with the reduction of neutropenia-related events are offset by the increased costs associated with improved chemotherapy administration. Cost savings due to the reduction in mortality and disease/symptoms and use of dose-dense regimens have not been adequately incorporated into previous cost-effectiveness studies. Available data suggest that using G-CSF in conjunction with antibiotics is more cost-effective than antibiotics alone when treating patients with SN/FN. Recent studies of biosimilars suggest that they are as effective as originator G-CSFs and, given their lower cost, could represent a cost-effective alternative. Finally, studies have not taken into consideration the indirect patient costs of experiencing a neutropenia-related event. CONCLUSION G-CSF use is effective in preventing SN/FN. Costs due to hospitalization and other neutropenia-related events are lower in patients treated with G-CSF as PP versus untreated patients. Despite this, many studies have not found solid evidence for the overall cost-effectiveness of PP use of G-CSF. One possibility for this is that patients receiving G-CSF prophylactically often receive more intense chemotherapy regimens, have better relative dose intensity, and fewer dose delays, and thereby have greater costs associated with chemotherapy administration than patients who do not receive G-CSF.

Abstract
OBJECTIVE To assess the use of colony-stimulating factors (CSFs) in patients with ovarian cancer who receive adjuvant paclitaxel and carboplatin chemotherapy in clinical practice and to assess whether the frequency of CSF use differs among hospitals in Japan. METHODS CSF use in patients with ovarian cancer who received first-line paclitaxel and carboplatin was analyzed retrospectively using data from the Japanese hospitalization payment system. RESULTS A total of 1,050 patients at 104 hospitals were identified. The median age was 60 years (range, 22 to 88 years). Of these, 163 patients (15.5%) were diagnosed with neutropenia and 134 patients (12.8%) received CSFs. Among the patients who received CSFs, 125 (93%) received them for the treatment of neutropenia without fever and 1 received them for febrile neutropenia. In total, CSFs were administered for 272 cycles of chemotherapy. Among them, CSFs were used as treatment for neutropenia without fever in 259 cycles (95%), as prophylaxis (primary or secondary) in 12 cycles (4%), and as treatment for febrile neutropenia in 1 cycle. Among hospitals, a median of 4.0% of patients received CSFs with an interquartile range of 25% (Q1, 0%; Q3, 25%). A logistic random effects model showed that the variation in the proportion of patients receiving CSFs among the 104 hospitals was 2.0 (p<0.001), suggesting that the use of CSFs varied across hospitals. CONCLUSION Most patients received CSFs for neutropenia without fever. Standardized and evidence-based use of CSFs is critically required among hospitals in Japan.

Abstract
Background Filgrastim or methionyl-granulocyte colony-stimulating factor (Met-G-CSF), is a recombinant therapeutic protein widely used to treat severe neutropenia caused by myelosuppressive drugs in patients with nonmyeloid malignancies. In addition to its role in the regulation of granulopoiesis, treatment with G-CSF is considered the standard approach to mobilize CD34 positive (CD34+) mononuclear cells for reconstituting hemopoietic ability for bone marrow transplantation. An intended biosimilar filgrastim (coded BK0023) was produced in GMP conditions by E.coli fermentation according to an original recombinant process and showed physico-chemical properties and purity profile similar to Neupogen®, a commercial preparation of filgrastim. The aim of the present study was to demonstrate the comparability of BK0023 to Neupogen® in terms of both in vitro biological activities and in vivo toxicology, pharmacokinetics and pharmacodynamics. Methods Cell proliferation and radioligand binding assays were conducted in NFS-60 cells to compare the biological activity and functional interaction with the G-CSF receptor in vitro, while preclinical in vivo studies, including pharmacokinetics and pharmacodynamics after repeated dose were performed in normal and neutropenic rats. A phase I study was carried out in healthy male volunteers treated by multiple-dose subcutaneous administration of BK0023 and Neupogen® to evaluate their pharmacodynamic effects as well as their pharmacokinetic and safety profile and to demonstrate their pharmacodynamic equivalence and pharmacokinetic bioequivalence. Results The results reported in this work demonstrate that BK0023 is comparable in terms of biological activity, efficacy and safety to Neupogen®. Conclusions BK0023 has the same pharmacokinetic profile, efficacy and safety as the reference commercial filgrastim Neupogen® and therefore could be further developed to become a convenient option to treat neutropenia in oncological patients.

Abstract
The purpose of this study was to use the most recent national data for a large cohort of patients diagnosed with breast cancer to evaluate temporal trend of receiving hematopoietic growth factors from 2000 to 2009 and to examine significant factors associated with increasing trends and geographic variations. We identified 26,130 women aged 65-89 years who were diagnosed with breast cancer and received chemotherapy in 2000-2009 from the Surveillance, Epidemiology, and End Results (SEER)-Medicare data. Colony-stimulating factors (CSFs) were identified if there was a claim from the following procedure codes: filgrastim, pegfilgrastim, or sargramostim. Erythropoiesis-stimulating agents (ESAs) were identified if there was a claim from the following procedure codes: epoetin or darbepoetin. Overall, 51.7% of patients with breast cancer received CSFs, which increased from 21.7% in 2000 to 63.2% in 2009. The percentage of patients receiving pegfilgrastim increased from 2.7% in 2000 to 19.5% in 2003 and then continuously to 49.7% in 2009. The overall percentage of patients receiving ESAs was 39.3%, which increased from 26.4% in 2000 to 60.8% in 2006, and then decreased significantly from 40.7% in 2007 to 12.9% in 2009. The receipt of both CSFs and ESAs differed significantly across different geographic areas. The receipt of CSFs continued to increase from 2000 to 2009, and pegfilgrastim started to replace filgrastim since 2003. The receipt of ESAs increased until 2006 and then declined substantially due to the black box warning. There were substantial geographic variations in the use of these hematopoietic growth factors.

Abstract
Granulocyte colony-stimulating factor (G-CSF) is a cytokine that has multiple roles in hematopoietic cells such as the regulation of proliferation and differentiation. Here, we describe fed-batch culture, refolding, and purification of rhG-CSF. The suitability of urea or sarcosine for solubilizing inclusion bodies (IBs) was tested. It was observed that urea is more efficient for solubilizing and refolding IBs than sarcosine is. The purity of rhG-CSF and the removal percentage of the rhG-CSF isoforms during purification were increased by pH 5.5 precipitation. The purity and the yield of purified rhG-CSF were 99% and 0.5 g of protein per liter culture broth, respectively. Our protocols of recombinant protein purification using ion exchange chromatography and semipreparative high performance liquid chromatography of pH-precipitated refolded solution may be informative to the industrial scale production of biopharmaceuticals.

Abstract
IMPORTANCE Although febrile neutropenia (FN) is a major source of morbidity and mortality for patients with solid tumors, little is known about the use of guideline-based care. OBJECTIVES To examine compliance with guideline-based recommendations for FN treatment, explore the factors that influence adherence to consensus guidelines, and analyze how the use of guideline-based care affects the outcomes. DESIGN The Perspective database was used to examine the treatment of cancer patients with FN from January 1, 2000, through March 31, 2010. To capture initial decision making, we examined treatment within 48 hours of hospital admission. We determined use of guideline-based antibiotics and nonguideline-based treatments, vancomycin, and granulocyte colony-stimulating factors (GCSF). Hierarchical models were developed to examine the factors associated with treatment. Patients were stratified into low- and high-risk groups, and the effect of the initial treatment on outcome (nonroutine hospital discharge and death) was examined. SETTING AND PARTICIPANTS Twenty-five thousand two hundred thirty-one patients with solid tumors hospitalized for neutropenia. MAIN OUTCOME MEASURE Use of guideline-based antibiotics, vancomycin, and GCSF and their affect on outcome. RESULTS Among 25 231 patients admitted with FN, guideline-based antibiotics were administered to 79%, vancomycin to 37%, and GCSF to 63%. Patients treated at high FN-volume hospitals (odds ratio [OR], 1.56; 95% CI, 1.34-1.81) by high FN-volume physicians (OR, 1.19; 95% CI, 1.03-1.38) and patients managed by hospitalists (OR, 1.49; 95% CI, 1.18-1.88) were more likely to receive guideline-based antibiotics (P < .05). Vancomycin use increased from 17% in 2000 to 55% in 2010, while GCSF use only decreased from 73% to 55%. Among low-risk patients with FN, prompt initiation of guideline-based antibiotics decreased discharge to a nursing facility (OR, 0.77; 95% CI, 0.65-0.92) and death (OR, 0.63; 95% CI, 0.42-0.95). CONCLUSIONS AND RELEVANCE While use of guideline-based antibiotics is high, use of the nonguideline-based treatments, vancomycin, and GCSF is also high. Physician and hospital factors are the strongest predictors of both guideline- and nonguideline-based treatment.

Abstract
Fever during neutropenia may be a symptom of severe life threatening infection, which must be treated immediately with antibiotics. If signs of infection persist, therapy must be modified. Diagnostic measures should not delay treatment. If the risk of febrile neutropenia after chemotherapy is ≥20%, then prophylactic therapy with G-CSF is standard of care. After protocols with a risk of febrile neutropenia of 10–20%, G-CSF is necessary, in patients older than 65 years or with severe comorbidity, open wounds, reduced general condition. Anemia in cancer patients must be diagnosed carefully, even preoperatively. Transfusions of red blood cells are indicated in Hb levels below 7–8 g/dl. Erythropoiesis stimulating agents (ESA) are recommended after chemotherapy only when hemoglobin levels are below 11 g/dl. The Hb-level must not be increased above 12 g/dl. Anemia with functional iron deficiency (transferrin saturation <20%) should be treated with intravenous iron, as oral iron is ineffective being not absorbed. Nausea or emesis following chemotherapy can be classified as minimal, low, moderate and high. The antiemetic prophylaxis should be escalated accordingly. In chemotherapy with low emetogenic potential steroids are sufficient, in the moderate level 5-HT3 receptor antagonists (setrons) are added, and in the highest level Aprepitant as third drug.

Abstract
Patients with a hematological malignancy are a heterogeneous patient population who are afflicted with diseases that range from rapidly fatal acute leukemia to indolent lymphoma or chronic leukemia. Treatment options for these patients range from observation to hematopoietic stem cell transplantation (HSCT), but all patients are more susceptible to infection. The problem of infection is dynamic with continued shifts in pathogenic organisms and microbial susceptibilities, new treatment regimens that further diminish immune function, and patients receiving treatment who are now older and frailer. The classic patterns of immunodeficiency for patients with a hematological malignancy include: periods of profound neutropenia, increased iatrogenic risks (i.e., central vascular catheters), and cellular immune suppression that affects HSCT recipients, patients with lymphoid malignancies, and those receiving treatment with corticosteroids or agents like alemtuzumab [1–4]. Recent advances in antimicrobial drug development, new technology, clinical trial results, and further clinical experience have enhanced the database on which to make infection prophylaxis and treatment decisions. However, the practicing clinician must remember that the majority of basic infection management principles for patients who are neutropenic remain unchanged.

Abstract
INTRODUCTION Febrile neutropenia is a relatively frequent event in cancer patients treated with chemotherapy and improvement in absolute neutrophil count (ANC) has been linked directly to improved outcome. Evaluation of granulocyte colony stimulating factors (GCSFs) for treatment has shown reduced incidences of episodes of prolonged neutropenia and protracted hospitalization. To determine absolute neutrophil counts with GCSF in febrile neutropenic cancer patients admitted to a tertiary care centre and to co-relate the improvement in ANC with mortality and hospital discharge. METHODS A prospective cross sectional study was carried at an oncology ward at Aga Khan University hospital from January 2010 to June 2011. All adult patients who were admitted and treated with GCSF for chemotherapy induced febrile neutropenia were included. Multivariable regression was conducted to identify the factors related with poor outcomes. RESULTS A total of 131 patients with febrile neutropenia were identified with mean age of 43.2 (18-85) years, 79 (60%) being ≤ 50. Seventy-five (57%) had solid tumors and 56 (43%) hematological malignancies, including lymphoma. Fifty seven (43.5%) had an ANC less 100 cells/mm(3), 34 (26%) one between 100-300 cells/mm(3) and 40 (31%) an ANC greater than 300 cells/mm(3). Thirty (23%) patients showed ANC recovery in 1-3 days, and 74(56%) within 4-7 days. Thirteen (10%) patients showed no recovery. The overall mortality was 18 (13.7%) patients. The mean time for ANC recovery seen in hematological malignancies was 6.34 days whereas for solid tumors it was 4.88 days. Patients with ANC <100 cells/mm(3) were more likely to die than patients with ANC >300 cells/mm(3) by a factor of 4.3. Similarly patients >50 years of age were 2.7 times more likely to die than younger patients. CONCLUSION Our study demonstrated that use of GCSF, in addition to intravenous antibiotics, in treatment of patients with chemotherapy induced febrile neutropenia accelerates neutrophil recovery, and shortens antibiotic therapy and hospitalization. We propose to risk classify the patients at the time of admission to evaluate the cost effectiveness of this approach in a resource constrained setup.

Abstract
Recent developments in cancer therapy have resulted in increases in treatment success rates and survival. One of thebasic goals of such therapy is improving patient quality of life. Chemotherapy protocols for solid or hematologicalmalignancies-most of which include multiple agents-negatively impact patient quality of life. Additionally, there havebeen developments in supportive care, which seeks to ameliorate or minimize the negative effects of chemotherapy.Herein we present a review and brief summarization of some of the agents used for supportive care in cancer patientsin light of the latest guidelines.

Abstract
OBJECTIVE Chemotherapy is vital for breast cancer management, but early-onset toxicities like neutropenia hinder its administration, especially in the elderly. Primary prophylactic (PP) use of granulocyte-colony stimulating factors (G-CSF) helps prevent neutropenia and its complications while receiving chemotherapy. Nevertheless, evidence supporting the effectiveness of PPG-CSF in the elderly is limited. Thus, the American Society of Clinical Oncology (ASCO) guidelines for PPG-CSF use in the elderly are not explicit. This study analyzed the effects of administration of PPG-CSF and duration of administration on the occurrence of chemotherapy-induced neutropenia hospitalizations in elderly breast cancer patients. METHODS This retrospective observational study of newly diagnosed breast cancer patients receiving chemotherapy used Surveillance, Epidemiology, and End Results-Medicare data from 1994 to 2003. To account for the nonrandom nature of the observational data, a nonparametric matching technique was used to preprocess the data before parametrically estimating the treatment effects. RESULTS Administration of PPG-CSF during the first course chemotherapy reduced neutropenia hospitalizations by 16% within the first 3 months and 17% within the first 6 months of chemotherapy initiation (P < 0.05). Hospitalization rates within the first 3 months of chemotherapy initiation were 3 times higher in women receiving less than 5 consecutive days of PPG-CSF compared with women receiving PPG-CSF for 5 or more days (P < 0.05). Hospitalization rates within the first 1 and 6 months were also lower with longer PPG-CSF duration (≥5 d) (P < 0.10). CONCLUSIONS PPG-CSF use is associated with reductions in in-patient healthcare utilization. These findings have implications for ASCO guidelines and Medicare coverage policies for PPG-CSF administration in elderly breast cancer patients.

Abstract
Febrile neutropenia (FN) continues to represent a major cause of morbidity, mortality, and cost in patients receiving cancer chemotherapy. The reported rates of FN vary considerably among studies depending on the treatment regimen, delivered dose intensity, and patient population. The risk of initial FN appears to be highest during the first cycle of chemotherapy and is greatest in certain high-risk groups including elderly patients and those with various comorbidities. Febrile neutropenia continues to have considerable clinical, economic, and quality-of-life impact on affected patients. The risk of mortality associated with FN continues to be relatively high in patients with hematologic malignancies, patients presenting with comorbid illnesses, and patients with bacteremia, pneumonia, or other infection-related complications. The reduction in chemotherapy dose intensity that frequently follows an episode of FN may have considerable life-threatening impact on disease control in responsive and potentially curable malignancies. The economic burden of FN is substantial, with the greatest proportion of the cost associated with the relatively limited number of patients hospitalized for prolonged periods as a result of comorbidities or complications. The colony-stimulating factors (CSFs) may reduce the risk and cost associated with cancer treatment by reducing the probability of hospitalization with FN. Primary prophylaxis with the CSFs may be warranted in patients receiving intensive regimens or in those at greater risk because of age or comorbidities. Further study of various risk factors for FN should help identify patients at greatest risk and likely candidates for targeted use of the hematopoietic growth factors.

Abstract
The role of granulocyte-macrophage-colony-stimulating factor (GM-CSF) in the supportive care of cancer patients has been evaluated with promising results. More recently, GM-CSF has been added to regimens for the mobilization of hematopoietic progenitor cells. An expanding role for GM-CSF in regulating immune responses has been recognized based upon its activity on the development and maturation of antigen presenting cells and its capability for skewing the immune system toward Th1-type responses. GM-CSF has been shown to preferentially enhance both the numbers and activity of type 1 dendritic cells (DC1), the subsets of dendritic cells responsible for initiating cytotoxic immune responses. The increase in DC1 content and activity following local and systemic GM-CSF administration support a role for GM-CSF as an immune stimulant and vaccine adjuvant in cancer patients. GM-CSF has shown clinical activity as an immune stimulant in tumor cell and dendritic cell vaccines, and may increase antibody-dependent cellular cytotoxicity. The successful use of myeloid acting cytokines to enhance anti-tumor responses will likely require the utilization of GM-CSF in combination with cytotoxic or other targeted therapies.

Abstract
This document updates and expands the initial Infectious Diseases Society of America (IDSA) Fever and Neutropenia Guideline that was published in 1997 and first updated in 2002. It is intended as a guide for the use of antimicrobial agents in managing patients with cancer who experience chemotherapy-induced fever and neutropenia. Recent advances in antimicrobial drug development and technology, clinical trial results, and extensive clinical experience have informed the approaches and recommendations herein. Because the previous iteration of this guideline in 2002, we have a developed a clearer definition of which populations of patients with cancer may benefit most from antibiotic, antifungal, and antiviral prophylaxis. Furthermore, categorizing neutropenic patients as being at high risk or low risk for infection according to presenting signs and symptoms, underlying cancer, type of therapy, and medical comorbidities has become essential to the treatment algorithm. Risk stratification is a recommended starting point for managing patients with fever and neutropenia. In addition, earlier detection of invasive fungal infections has led to debate regarding optimal use of empirical or preemptive antifungal therapy, although algorithms are still evolving. What has not changed is the indication for immediate empirical antibiotic therapy. It remains true that all patients who present with fever and neutropenia should be treated swiftly and broadly with antibiotics to treat both gram-positive and gram-negative pathogens. Finally, we note that all Panel members are from institutions in the United States or Canada; thus, these guidelines were developed in the context of North American practices. Some recommendations may not be as applicable outside of North America, in areas where differences in available antibiotics, in the predominant pathogens, and/or in health care-associated economic conditions exist. Regardless of venue, clinical vigilance and immediate treatment are the universal keys to managing neutropenic patients with fever and/or infection.

Abstract
OBJECTIVES We examined health care use in conjunction with primary prophylaxis use of colony stimulating factors (CSF) during patients' initial course of chemotherapy. METHODS This retrospective cohort study identified adults aged 25 years and older with a diagnosis of breast, colorectal, or nonsmall cell lung cancer between 2002 and 2005 from the Western Washington Surveillance Epidemiology and End Results Puget Sound registry. We linked these records to health insurance claims from four payers representing 75% of those insured in the state. Claims records were used to determine chemotherapy regimen type, CSF use, febrile neutropenia occurrences, and supportive care. Chemotherapy regimens were categorized as conferring high, intermediate, or low risk of myelosuppression according to the National Comprehensive Cancer Network guidelines. CSF use was described as primary prophylaxis, other, or none. Antibiotics and antifungal and antiviral agents per National Comprehensive Cancer Network guidelines for supportive care for cancer infection were categorized using Healthcare Common Procedure Coding System and National Drug Code assignments. RESULTS Use of CSF as primary prophylaxis is not significantly associated with a reduction in antibiotic use or inpatient or outpatient visits. Primary prophylactic CSF use was associated with less use of antiviral drugs. CONCLUSIONS CSF use is not associated with a reduction in health care use, with the exception of antiviral drug use. Given the expense associated with CSF use, pragmatic trials and additional research are needed to further assess the affects of CSF on health care use.
