Abstract
Background Febrile neutropenia (FN) is a life-threatening oncologic emergency requiring timely evaluation and treatment. Unrecognized fever and infection can progress quickly and have been shown to increase morbidity and mortality in patients with malignancy. It is critical to identify patients with neutropenic fever on presentation to the emergency department (ED) and to initiate treatment immediately. Observations This quality improvement initiative sought to optimize ED care of patients presenting with FN. Delays in antibiotic prescribing for patients with FN presenting to the ED were identified. A protocol was implemented to streamline clinical decision making and decrease the time from triage to the first dose of antibiotics in the ED. Key interventions included obtaining ED staff support, developing a standard empiric therapy protocol, increasing prescriber awareness of the neutropenic fever protocol and integrating it into the electronic health record. Before the protocol, the mean time from triage to the first dose of antibiotics was 3.3 hours with only 6% of patients receiving appropriate empiric therapy within 1 hour. Postimplementation, the average time to antibiotics decreased to 2.3 hours. In the postimplementation group, 17% of patients within 1 hour. Conclusions Early identification and timely empiric antibiotic therapy are critical to improving outcomes for patients presenting to the ED with FN. Additional optimization of the order sets along with increased protocol comfort and staff education will help to further reduce the time to antibiotic administration in alignment with guideline recommendations.

Abstract
Chemotherapy-induced febrile neutropenia (FN) is a medical emergency that may occur in patients with malignancies receiving myelosuppressive chemotherapy. FN requires early therapeutic intervention since it is associated with increased hospitalizations and high mortality risk of 5%-20%. FN-related hospitalizations are higher in patients with myeloid malignancies than in those with solid tumors due to the myelotoxicity of chemotherapy regimens and the compromised bone marrow function. FN increases the burden of cancer by causing chemotherapy dose reductions and delays. The administration of the first granulocyte colony-stimulating factor (G-CSF), filgrastim, reduced the incidence and duration of FN in patients undergoing chemotherapy. Filgrastim later evolved into pegfilgrastim, which has a longer half-life than filgrastim and was associated with a lower rate of severe neutropenia, chemotherapy dose reduction, and treatment delay. Nine million patients have received pegfilgrastim since its approval in early 2002. The pegfilgrastim on-body injector (OBI) is an innovative device facilitating the time-released auto-injection of pegfilgrastim approximately 27 hours after chemotherapy, as clinically recommended for the prevention of FN, thus eliminating the need for a next-day hospital visit. Since its introduction in 2015, one million patients with cancer have received pegfilgrastim using the OBI. Subsequently, the device has been approved in the United States (US), European Union, Latin America, and Japan, with studies and a postmarketing commitment demonstrating device reliability. A recent prospective observational study conducted in the US demonstrated that the OBI substantially improved the adherence to and compliance with clinically recommended pegfilgrastim therapy; patients receiving pegfilgrastim via the OBI experienced a lower incidence of FN than those receiving alternatives for FN prophylaxis. This review discusses the evolution of G-CSFs leading to the development of the OBI, current recommendations for G-CSF prophylaxis in the clinic, continued evidence supporting next-day pegfilgrastim administration, and improvements in patient care made possible with the OBI.

Cost-effectiveness of pegfilgrastim versus filgrastim for prevention of chemotherapy-induced febrile neutropenia in patients with lymphoma: a systematic review. BMC Health Serv Res 2022; 22:1600. [PMID: 36585648 PMCID: PMC9805270 DOI: 10.1186/s12913-022-08933-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Accepted: 12/05/2022] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Febrile neutropenia (FN) is a prevalent and potentially life-threatening complication in patients with lymphoma receiving myelosuppressive chemotherapy. Pegfilgrastim is more effective than filgrastim as prophylaxis for FN. However, its usage has been limited because of its higher cost. Pegfilgrastim's value for money remains unclear. OBJECTIVE To systematically review the cost-effectiveness of pegfilgrastim compared to filgrastim as a primary or secondary prophylaxis for chemotherapy-induced FN among patients with lymphoma. METHODS A systematic literature search was conducted in PubMed, EMBASE, Cochrane Library databases, and Google Scholar. The most widely used economic evaluations (cost-effectiveness analysis, cost-utility analysis and cost-benefit analysis) were included in the review. Data extraction was guided by the Consolidated Health Economic Evaluation Reporting Standards checklist, and the quality of reviewed articles was assessed using the Joanna Briggs Institute (JBI) checklist. Cost-effectiveness data were rigorously summarized and synthesized narratively. Costs were adjusted to US$ 2020. RESULTS We identified eight economic evaluation studies (two cost-utility analyses, three cost-effectiveness analyses, and three studies reporting both cost-effectiveness and cost-utility analyses). Half of these studies were from Europe (n = 4), the other half were from Iran, USA, Canada, and Singapore. Six studies met > 80% of the JBI quality assessment criteria. Cost-effectiveness estimates in the majority (n = 6) of these studies were for Non-Hodgkin Lymphoma patients receiving myelosuppressive chemotherapy with high-risk of FN (> 20%). The studies considered a wide range of baseline FN risk (17-97.4%) and mortality rates (5.8-8.9%). Reported incremental cost-effectiveness ratios ranged from US$ 2199 to US$ 8,871,600 per quality-adjusted life-year (QALY) gained, dominant to US$ 44,358 per FN averted, and US$ 4261- US$ 7251 per life-years gained. The most influential parameters were medication and hospitalization costs, the relative risk of FN, and assumptions of mortality benefit. CONCLUSIONS Most studies showed that pegfilgrastim is cost-effective compared to filgrastim as primary and secondary prophylaxis for chemotherapy-induced FN among patients with lymphoma at a cost-effectiveness threshold of US$ 50,000 per QALY gained. The findings could assist clinicians and healthcare decision-makers to make informed decisions regarding resource allocation for the management of chemotherapy-induced FN in settings similar to those studied.

Effects of Prophylactic Administration of Granulocyte Colony-Stimulating Factor on Peripheral Leukocyte and Neutrophil Counts Levels After Chemotherapy in Patients With Early-Stage Breast Cancer: A Retrospective Cohort Study. Front Oncol 2022; 12:777602. [PMID: 35547875 PMCID: PMC9084938 DOI: 10.3389/fonc.2022.777602] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2021] [Accepted: 03/15/2022] [Indexed: 11/13/2022] Open
Abstract
Background Both chemotherapy-induced neutropenia (CIN) and febrile neutropenia (FN) frequently occur and can lead to dose-limiting toxicity and even fatal chemotherapy side effects. The prophylactic use of recombinant human granulocyte colony-stimulating factor (rhG-CSF), including pegylated rhG-CSF (PEG-rhG-CSF), significantly reduces the risks of CIN and FN during chemotherapy in early-stage breast cancer (ESBC) patients. However, whether the prophylactic use of granulocyte colony-stimulating factor (G-CSF), especially PEG-rhG-CSF, can influence white blood cell (WBC) counts and absolute neutrophil counts (ANCs) after finishing the chemotherapy remains unknown. Therefore, exploring the development and recovery tendency of WBC counts and ANCs during and after chemotherapy is crucial. Objective We aimed to investigate the variation tendency and recovery of WBC counts and ANCs during and after chemotherapy and evaluate the independent factors influencing leukopenia and neutropenia lasting longer after chemotherapy. We also aimed to provide individualized prophylactically leukocyte elevation therapy for breast cancer patients. Methods This single-center retrospective cohort study evaluated 515 ESBC patients who received rhG-CSF or PEG-G-CSF for prophylaxis after adjuvant or neoadjuvant chemotherapy. Blood test reports were analyzed during chemotherapy, and on a 12-month follow-up period after finishing the chemotherapy. The WBC counts and ANCs were measured to assess their variation tendency characteristics and to identify independent factors that influenced the occurrence of leukopenia and neutropenia lasting longer than 12 months after chemotherapy. Results Prophylaxis with rhG-CSF or PEG-rhG-CSF kept the mean values of WBC counts and ANCs within the normal range during chemotherapy, but a significant difference in WBC levels was detected before the end of the last chemotherapy compared to the prechemotherapy period (baseline) (p < 0.001). During the 12-month follow-up after the end of the last chemotherapy, WBC counts and ANCs gradually recovered, but the group that used only PEG-rhG-CSF (long-acting group, p WBC = 0.012) or rhG-CSF (short-acting group, p WBC = 0.0005) had better leukocyte elevation effects than the mixed treatment group (PEG-rhG-CSF mixed rhG-CSF). Besides, the short-acting group had a better neutrophil elevation effect than the longer-acting (p ANC = 0.019) and mixed (p ANC = 0.002) groups. Leukopenia was still present in 92 (17.9%) patients and neutropenia in 63 (12.2%) 12 months after the end of the last chemotherapy. The duration of leukopenia over 12 months was closely associated with the baseline WBC level (p < 0.001), G-CSF types (p = 0.027), and surgical method (p = 0.041). Moreover, the duration of neutropenia over 12 months was closely related to the baseline ANC (p < 0.001), G-CSF types (p = 0.043), and molecular typing (p = 0.025). Conclusion The prophylactic application of G-CSF effectively stabilized the WBC counts and ANCs during chemotherapy in ESBC patients. Nevertheless, the recovery of WBC counts and ANCs after chemotherapy varied between different G-CSF treatment groups. The risk of leukopenia and neutropenia persisting for more than 12 months after chemotherapy was associated with G-CSF types, the baseline level of WBC count/ANCs, surgical method, and molecular typing.

Abstract
BACKGROUND: Febrile neutropenia occurs in more than 80% of patients with hematological malignances specially after chemotherapy cycles and an infectious source is identified in approximately 20–30%. Various bacterial, viral, and fungal pathogen contribute to the development of neutropenic fever and without prompt antibiotic therapy mortality rate can be as high as 70%.
AIM: The objective of the study was to document the current sites of infection in patients with febrile neutropenia in hematological ward in Baghdad Teaching Hospital, the microorganisms and antibiotic susceptibly in culture positive cases and mortality rate in 1 week and 4 weeks after episode of fever.
PATIENTS AND METHODS: One hundred cases of febrile neutropenia were evaluated in Hematological Ward of Baghdad Teaching Hospital from January 2019 to January 2020. Detailed history, physical examination, and laboratory investigations were conducted and statistical analysis of the results was done.
RESULTS: One hundred cases of febrile neutropenia, mean age of presentation was 41.56 ± 10.5 years. Acute myeloid leukemia (36%) and acute lymphocytic leukemia (26%) were the most common underlying hematological disorder, followed by Aplastic Anemia, Non-Hodgkin Lymphoma, and Hodgkin Lymphoma. Temperature ranged from 38°C to 39°C with mean temperature of 38.4°C and most of the patient presented with short duration of fever, 57% had absolute neutrophil count below 150 cells/μL with mean duration of neutropenia was 14.01 days. Respiratory tract was the most common site of infection (52%) followed by urinary tract (18%) and in 16% had no obvious focus of infection. Thirty percent of cases were culture Gram-positive and Gram-negative microorganism which were more common 62.9% which were generally sensitive to Aminoglycosides while Gram-positive microorganism constituted 29.6% of isolated bacteria and were generally sensitive to vancomycin. No mortality documented 1 and 4 weeks after fever.
CONCLUSION: We concluded that the most frequent sites of infection in patient with febrile neutropenia were respiratory tract followed by urinary tract infection, while 16% had undetermined source of infection. Thirty percent of patients had a positive blood culture with Escherichia coli being the most common infecting microorganism, Gram-negative microorganisms were more common than Gram-positive microorganism and fungal infection constituted about 6% of growth. Significant association was found between the fever and longer duration of neutropenia and the greater severity of neutropenia was observed. No mortality related to febrile neutropenia was documented.

Abstract
BACKGROUND Earlier initial antibiotic treatment for febrile neutropenia is associated with improved clinical outcomes. This study was conducted to evaluate the association of an emergency department (ED) intervention protocol with time to initial antibiotic treatment for febrile neutropenia patients. METHODS We conducted a cohort study of adult ED febrile neutropenia patients before and after implementation of an intervention protocol. Analyses included comparison of means and medians, Kaplan-Meier estimates, multivariable regression analyses, interrupted time-series analyses, and causal mediation analyses. The intervention protocol included specific triage and process-of-care actions to reduce the primary outcome of time to initial antibiotic treatment. RESULTS There were 69 patients in the 12-month preintervention period and 52 patients in the 8-month postintervention period. The mean (±SD) times to initial antibiotics were 197.6 (±85.4) min for the preintervention group and 97.7 (±51.0) min for the postintervention group (difference of 99.9 min with 95% confidence interval [CI] = 73.5 to 126.4, p < 0.001). The patients' probability for receiving initial antibiotics within 90 min was severalfold greater (adjusted risk ratio = 10.31, 95% CI = 4.99 to 21.30, p < 0.001) for the postintervention group versus preintervention group. ED length of stay, hospital length of stay, 30-day readmissions, and 30-day all-cause mortality were not different between the study groups. The association of the intervention protocol with time to initial antibiotics appeared to be mediated through times to treatment room placement, report of absolute neutrophil count, and initial antibiotic order. CONCLUSIONS The intervention protocol was associated with a significant reduction in time to initial antibiotics for ED patients with febrile neutropenia. This association appears to be facilitated through specific intermediate process-of-care variables. A larger multicenter study is needed to assess the potential effects of an ED febrile neutropenia protocol on patient-centered clinical outcomes and resource utilization.

Abstract
Introduction Febrile neutropenia (FN) is a dreaded complication of cancer chemotherapy and frequently associated with respiratory infections. Flexible bronchoscopy (FB) serves as a useful diagnostic tool in this regard. Objective To determine the diagnostic yield, safety and clinical implications of bronchoalveolar lavage (BAL) in cancer patients with FN, having lung infiltrates on radiographic chest imaging. Methods We reviewed medical records of FN patients who underwent FB at Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, from July 2015 till July 2018. The culture yield of BAL, resultant change of management and outcome over the subsequent 30 days were retrospectively analysed. Statistical Package for Social Sciences (SPSS) version 20 (IBM Corp., Armonk, NY) was used for data analysis. Results Ninety FN patients, with mean age 26 ± 18 years and predominantly males (65.6%, n = 59) were included in the study. Seventy-seven (85.6%) had hematological and 13 (14.4%) solid organ malignancy. The mean absolute neutrophil count was 0.20 +/- 0.36/ µL. BAL cultures were diagnostic in 40 (44%) patients; the etiology was bacterial, fungal and mixed in 25 (62.5%), 14 (35%) and one (2.5%) patient, respectively. All patients were on empirical antibiotics prior to bronchoscopy: 32 (35.6%) on antibacterial alone and 58 (64.4%) on antibacterial plus antifungal therapy. Change of management occurred in 51 (56.7%) patients after BAL results, including de-escalation from dual antibiotics in 28 (55%) and initiation of new culture sensitive antibiotic in 23 (45%). FB-associated complications developed in three (5.6%) non-intensive care patients (ICU), including transient hypoxia in two and minor hemoptysis in one patient, while five (14.8%) mechanically ventilated patients in ICU experienced worsening of oxygenation parameters within 48 hours. Overall, 24 (26.7%) patients died. Mortality was 3.7% in non-ICU and 69% in ICU setting and significantly higher in patients with fungal pneumonias (p-value 0.01) and with prolonged neutropenia (p-value 0.001). Conclusions BAL is a safe diagnostic tool for FN patients with lung infiltrates, with minimal complications and sufficient diagnostic yield to improve diagnosis and management of such patients.

Abstract
The worldwide epidemic of three coronaviruses and one influenza virus in 21st century have seriously threatened human health. Infection with these viruses can cause respiratory symptoms. The patients with lung cancer are more susceptible to viral infection and have a worse prognosis due to the advanced age and the systemic immunosuppressive state caused by malignancy itself and the anticancer treatments. In addition, without sufficient clinical awareness, a missed diagnosis of viral pneumonia may occur due to the fever and respiratory symptoms caused by lung cancer and its secondary diseases. Furthermore, control measures against viral outbreaks may interfere with routine diagnosis and treatment of lung cancer patients. Therefore, scientific protection and individualized management of lung cancer patients are particularly important during virus epidemic prevention and control. Here, we systematically reviewed the epidemiological and clinical characteristics of viral pneumonia, its impact on patients with lung cancer and the differential diagnosis of lung cancer-related respiratory manifestations, aiming to provide guidance for the individual management of lung cancer patients during the prevention and control of viral pneumonia epidemic.

Abstract
BACKGROUND Febrile neutropenia (FN) has been associated with high mortality among adults with cancer. Current systems for early detection of inpatient FN mortality are based on scoring indexes that require intensive physicians' subjective evaluation. OBJECTIVE In this study, we leveraged machine learning techniques to build a FN mortality risk evaluation tool focused on FN admissions without physicians' subjective evaluation. METHODS We used the National Inpatient Sample and Nationwide Inpatient Sample (NIS) that included mortality data among adult inpatients who were diagnosed with FN during a hospital admission. Machine learning techniques that we compared included linear models (ridge logistic regression and linear support vector machine) and non-linear models (gradient boosting tree and neural network). The primary outcome for this study was death among individuals with a recorded FN admission. Model comparison was evaluated based on areas under the receiver operating characteristic curve (AUROC) and model performance was estimated using 30 % test set created via stratified split. RESULTS Our analysis detected 126,013 adult admissions within the NIS data that were diagnosed with FN, among which 5,856 were declared as deceased (4.6 %). Our machine learning results demonstrate linear models and non-linear models achieved areas under the receiver operating characteristic (AUROC) around 92 % in survival prediction. CONCLUSIONS We developed machine learning models that do not require physicians' subjective evaluation for FN mortality risk prediction.

Abstract
BACKGROUND Cancer is associated with a variety of complications, including neutropenic fever, which can result in severe morbidity and mortality. This oncologic emergency requires ED management. OBJECTIVE This narrative review provides focused updates for emergency clinicians regarding neutropenic fever. DISCUSSION Neutropenic fever is defined by fever with oral temperature >38.3°C or temperature >38.0°C for 1 hour with an absolute neutrophil count (ANC) < 1000 cells/microL. Patients who have received chemotherapy within 6 weeks of presentation are at high risk for neutropenia. While most patients with neutropenic fever do not have an identifiable bacterial source of fever, clinicians should treat patients for bacterial infection. Rapid assessment and management are vital to improving outcomes in patients with suspected or confirmed neutropenic fever. History and examination should focus on the most common sites of infection: the gastrointestinal tract, blood, skin, lung, and urinary tract. However, physical examination and laboratory or imaging assessment may not display classic signs of infection. Blood cultures should be obtained, and broad-spectrum antibiotics are recommended. Oncology consultation is an integral component in the care of these patients. Several risk scores can assist in stratifying patients who may be appropriate for discharge home and follow-up. CONCLUSIONS Neutropenic fever is an oncologic emergency. Rapid diagnosis and care of patients with neutropenic fever can improve outcomes, along with oncology consultation.

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
Oncology patients are a unique patient population in the emergency department (ED). Malignancy and associated surgical, chemotherapeutic, or radiation therapies put them at an increased risk for infection. The most ominous development is neutropenic fever, which happens often and may not present with signs or symptoms other than fever. A broad differential diagnosis is essential when considering infectious disease pathology in both neutropenic and non-neutropenic oncology patients in the ED.

Febrile neutropenia in adjuvant and neoadjuvant chemotherapy for breast cancer: a retrospective study in routine clinical practice from a single institution. Support Care Cancer 2018; 26:4097-4103. [PMID: 29855772 DOI: 10.1007/s00520-018-4280-4] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2017] [Accepted: 05/17/2018] [Indexed: 12/30/2022]
Abstract
BACKGROUND Febrile neutropenia (FN) is one of the most common and most critical adverse effects of chemotherapy. Despite many existing guidelines based on the use of granulocyte-colony stimulating factor (G-CSF), FN continues to impair the quality of life and interfere with the treatment of many patients. The purpose of this study was to assess the incidence and management of FN associated with chemotherapy for early breast cancer in routine clinical practice. METHODS All patients with early-stage breast cancer (ESBC) treated by chemotherapy at Institut Curie, Hôpital René Huguenin, in 2014 were retrospectively included. The incidence and management of FN were reported. Risk factors associated with FN were studied by robust-error-variance Poisson regression. RESULTS A total of 524 patients received either neoadjuvant (N = 130) or adjuvant chemotherapy (N = 394). Most patients (80%) were treated with a combination of 5-fluorouracil, epirubicin, and cyclophosphamide (FEC100; 3 cycles) followed by docetaxel 100 mg/m2 (D; 3 cycles). The overall incidence of FN was 17%. Eighteen percent of patients received primary prophylaxis (PP) for FN with G-CSF, using pegfilgrastim in 64% of cases and 74% of patients over the age of 70 received PP. Less than 5% of patients who received PP experienced FN. Recurrent FN after secondary prophylaxis was observed in 9% of patients. Forty-seven percent of cases of FN occurred after the first cycle and 30% occurred after the fourth cycle, corresponding to D ± trastuzumab (T). The FEC100 regimen was associated with a relative risk of FN of 1.98 (p = 0.09). Autoimmune (AI) and inflammatory diseases were associated with a higher risk of FN (RR 3.08; p < 0.01). No significant difference in the incidence of FN was observed between adjuvant and neoadjuvant chemotherapy. FN was managed on an outpatient basis in 72% of cases. Outpatients with FN were mainly treated by a combination of amoxicillin-clavulanic acid and ciprofloxacin. Dose reduction or chemotherapy regimen modification were necessary in 25% of patients after FN. No toxic death was reported. CONCLUSION The incidence of FN induced by adjuvant/neoadjuvant chemotherapy in ESBC is higher in routine clinical practice than in clinical trials. AI or inflammatory diseases were significant independent risk factors for FN. Primary prophylaxis in patients at risk (elderly, comorbid patients), especially treated with the FEC regimen, is the keystone of management of this adverse effect. Prevention and management of FN to ensure the patient's safety and quality of life are a major issue for both medical oncologists and supportive care physicians.

Int J Antimicrob Agents 2018; 52:350-357. [PMID: 29751120 DOI: 10.1016/j.ijantimicag.2018.04.017] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2018] [Revised: 04/18/2018] [Accepted: 04/29/2018] [Indexed: 11/28/2022]
Abstract
Febrile neutropenia (FN) is associated with substantial morbidity and necessitates empirical broad-spectrum antimicrobial treatment. In this prospective cohort study, a risk-guided management strategy for FN using empirical piperacillin/tazobactam (TZP) or a carbapenem was evaluated. The analysis involved 723 FN episodes in hospitalised adult patients, including those with severe sepsis or prior infection/colonisation with extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae. Propensity score matching analysis was used to adjust for baseline differences between treatment groups and produced 267 matched pairs. The primary outcome was all-cause mortality. Secondary outcomes were the incidences of drug-resistant Gram-negative (including ESBL-producing) and Gram-positive bacterial isolates and of invasive pulmonary aspergillosis (IPA) and their associated mortality. There was no difference in mortality between empirical carbapenem and TZP [18/267 (6.7%) vs. 14/267 (5.2%); P = 0.466]. Higher incidences of drug-resistant Gram-negative isolates [77/267 (28.8%) vs. 26/267 (9.7%); P < 0.001], including ESBL-producing bacteria [57/267 (21.3%) vs. 16/267 (6.0%); P < 0.001], were observed in carbapenem-treated episodes where its use lowered mortality. Mortality rates for ESBL-positive infections were 5.3% (3/57) and 25.0% (4/16) (P = 0.037) and for drug-resistant Gram-negative infections were 6.5% (5/77) and 23.1% (6/26) (P = 0.018) in carbapenem- and TZP-treated episodes, respectively. More IPA was observed with carbapenem use [16/267 (6.0%) vs. 6/267 (2.2%); P = 0.029]. Antifungal prophylaxis reduced the risk of death (odds ratio = 0.39, 95% confidence interval 0.17-0.87; P = 0.017). Risk-guided carbapenem prescribing in FN correctly identified cases prone to drug-resistant Gram-negative infections and reduced the mortality in these episodes.

Cost-Utility Analysis of Lipegfilgrastim Compared to Pegfilgrastim for the Prophylaxis of Chemotherapy-Induced Neutropenia in Patients with Stage II-IV Breast Cancer. Front Pharmacol 2017; 8:614. [PMID: 28955224 PMCID: PMC5601405 DOI: 10.3389/fphar.2017.00614] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2017] [Accepted: 08/23/2017] [Indexed: 11/13/2022] Open
Abstract
Background: Lipegfilgrastim (Lonquex®) has demonstrated to be non-inferior to pegfilgrastim (Neulasta®) in reducing the duration of severe neutropenia (SN) in patients with stage II-IV breast cancer. Compared to pegfilgrastim, lipegfilgrastim also demonstrated statistically significant lower time to ANC recovery in cycles 1-3, lower incidence of SN in cycle 2 and lower depth of absolute neutrophil count (ANC) nadir in cycles 2 and 3. The aim of this study was to quantify the cost utility of lipegfilgrastim compared to pegfilgrastim in stage II-IV breast cancer patients, taking the perspective of the Belgian payer over a lifetime horizon. Methods: Two Markov models were developed to track on- and post-chemotherapy related complications, including SN, febrile neutropenia (FN), chemotherapy dose delay, chemotherapy relative dose intensity of less than 85%, infection, death rates, and quality-adjusted life years (QALYs). Data on costs (2015 value) and effects were obtained from literature, national references, and complemented by a survey of clinical experts using a modified Delphi method. Both deterministic and probabilistic sensitivity analyses were carried out. Outcomes measures included costs, QALYs and life-years (LY). Results: At current equivalent price of €1,169, treatment with lipegfilgrastim was associated with overall costs of €9,845 vs. €10,208 for pegfilgrastim and overall QALYs of 13.977 vs. 13.925 for pegfilgrastim. Life expectancy was increased by 21 days (or 0.058 LY gained). The difference in costs stem from avoided infection, SN and FN cases in the lipegfilgrastim compared to the pegfilgrastim group. Similarly, the difference in QALYs was explained by the difference in the number of patients in the chemotherapy/G-CSF Markov state followed by infection and FN between lipegfilgrastim and pegfilgrastim. The probability of lipegfilgrastim to be cost-effective compared to pegfilgrastim was 68, 79, and 83% at the willingness-to-pay thresholds (WTP) of €10,000, €30,000 and €50,000 per QALY gained, respectively. At a WTP threshold of €30,000 per QALY gained, lipegfilgrastim was cost-effective up to €1,500 across all age bands and cancer stages, compared to the current price. Conclusions: Lipegfilgrastim is a cost-effective use of health care resources in patients with stage II-IV breast cancer.

Abstract
Introduction: Febrile neutropenia (FN) is an oncological emergency. The choice of empiric therapy depends on the locally prevalent pathogens and their sensitivities, the sites of infection, and cost. The Infectious Diseases Society of America guidelines are being followed for the management of FN in India. Methods: This is a prospective observational study conducted at a tertiary care cancer centre from September 2012 to September 2014. Objectives: The objectives of this study were as follows: (1) To review the pattern of microbial flora, susceptibility pattern, and important clinical variables among bloodstream infections in febrile neutropenic patients with solid tumors and hematological malignancies. (2) As per the institutional protocol to periodically review the antibiotic policy and susceptibility pattern, and compare the findings with an earlier study done in our institute in 2010. This was a prospective study conducted from September 2012 to September 2014. Results: About 379 episodes of FN were documented among 300 patients. About 887 blood cultures were drawn. Of these, 137 (15%) isolates were cultured. Isolates having identical antibiograms obtained from a single patient during the same hospitalization were considered as one. Hence, 128 isolates were analyzed. About 74 (58%) cultures yielded Gram-negative bacilli, 51 (40%) were positive for Gram-positive cocci, and 3 (2%) grew fungi. Among Gram-negative organisms, Escherichia coli followed by Acinetobacter baumannii and Klebsiella pneumoniae accounted for 78% of the isolates. Among Gram-positive cocci, Staphylococcus species accounted for 84% of the isolates. We have noted a changing trend in the antibiotic sensitivity pattern over the years. Following the switch in empirical antibiotics, based on the results of the study done in 2010 (when the empirical antibiotics were ceftazidime + amikacin), the sensitivity to cefoperazone-sulbactam has plunged from about 80% to 60%%. Similar reduction in susceptibility was noted for piperacillin-tazobactam, imipenem, and meropenem. On the contrary, there was a marked increase in sensitivity to ceftazidime (50–76%). Based on these results, we have reverted to ceftazidime + amikacin as the empirical antibiotics. Conclusion: Every institute must have a regular revision of antibiotic policy based on periodic assessment of the clinical and microbiological profile in FN. This will combat antibiotic resistance.

Abstract
The adoption of primary (PP) versus secondary prophylaxis (SP) of febrile neutropenia (FN), with granulocyte colony-stimulating factors (G-CSF), for adjuvant chemotherapy (AC) regimens in breast cancer (BC) could be affected by its "value for money". This systematic review examined (i) cost-effectiveness of PP versus SP, (ii) FN threshold at which PP is cost-effective including the guidelines 20 % threshold and (iii) potential impact of G-CSF efficacy assumptions on outcomes. The systematic review identified all cost-effectiveness/cost-utility analyses (CEA/CUA) involving PP versus SP G-CSF for AC in BC that met predefined inclusion/exclusion criteria. Five relevant CEA/CUA were identified. These CEA/CUA examined different AC regimens (TAC = 2; FEC-D = 1; TC = 2) and G-CSF formulations (filgrastim "F" = 4; pegfilgrastim "P" = 4) with varying baseline FN-risk (range 22-32 %), mortality (range 1.4-6.0 %) and utility (range 0.33-0.47). The potential G-CSF benefit, including FN risk reduction with P versus F, varied among models. Overall, relative to SP, PP was not associated with good value for money, as per commonly utilized CE thresholds, at the baseline FN rates examined, including the consensus 20 % FN threshold, in most of these studies. The value for money associated with PP versus SP was primarily dependent on G-CSF benefit assumptions including reduced FN mortality and improved BC survival. PP G-CSF for FN prevention in BC patients undergoing AC may not be a cost-effective strategy at the guidelines 20 % FN threshold.

Abstract
Severe neutropenia induced by chemotherapy or conditioning for hematopoietic cell transplantation often results in morbidity and mortality due to infection by opportunistic pathogens. A system has been developed to generate ex vivo-expanded mouse myeloid progenitor cells (mMPCs) that produce functional neutrophils in vivo upon transplantation in a pathogen challenge model. It has previously been demonstrated that transplantation of large numbers of freshly isolated myeloid progenitors from a single donor provides survival benefit in radiation-induced neutropenic mice. In the present work, an ex vivo-expanded and cryopreserved mMPC product generated from an allogeneic donor pool retains protective activity in vivo in a lethal fungal infection model. Infusion of the allogeneic pooled mMPC product is effective in preventing death from invasive Aspergillus fumigatus in neutropenic animals, and protection is dose dependent. Cell progeny from the mMPC product is detected in the bone marrow, spleen, blood, and liver by flow cytometry 1 week postinfusion but is no longer evident in most animals 4 weeks posttransplant. In this model, the ex vivo-generated pooled allogeneic mMPC product (i) expands and differentiates in vivo; (ii) is functional and prevents death from invasive fungal infection; and (iii) does not permanently engraft or cause allosensitization. These data suggest that an analogous ex vivo-expanded human myeloid progenitor cell product may be an effective off-the-shelf bridging therapy for the infectious complications that develop during hematopoietic recovery following hematopoietic cell transplantation or intensive chemotherapy.

Abstract
PURPOSE The purpose of this study is to determine the incidence of febrile neutropenia (FN) among women receiving FEC-D (flurouracil 500 mg/m(2), epirubicin 100 mg/m(2), and cyclophosphamide 500 mg/m(2) every 3 weeks for three cycles followed by docetaxel 100 mg/m(2) every 3 weeks for three cycles) chemotherapy for early stage breast cancer (ESBC) and the impact of primary granulocyte colony-stimulating factor (G-CSF) prophylaxis in a non-clinical trial setting. PATIENTS AND METHODS A retrospective chart review of women referred for ESBC to The Moncton Hospital between 2005 and 2010 evaluated patient and disease characteristics, adjuvant chemotherapy receipt, G-CSF usage, FN incidence, hospital admission rates, and length of stay. Association of variables with FN was examined, and exploratory multivariable logistic regression modeling examined the impact of baseline variables on risk of FN. RESULTS Of 520 patients enrolled in the database, 251 (48.3 %) received adjuvant chemotherapy for ESBC. Most (66.9 %) received FEC-D. Overall, 55 (21.9 %) patients developed FN. Forty-four (26.2 %) patients on FEC-D developed FN. Forty of 129 (31.0 %) FEC-D patients who did not receive primary G-CSF prophylaxis developed FN, versus 4 of 39 (10.3 %) receiving G-CSF. Receipt of FEC-D or TC (docetaxel 75 mg/m(2) and cyclophosphamide 600 mg/m(2) every 3 weeks for four or six cycles) was associated with odds ratios of 6.5 or 6.77, respectively, for the development of FN. Receipt of trastuzumab with chemotherapy was associated with an odds ratio of 3.48 for developing FN versus no trastuzumab. Primary G-CSF prophylaxis led to a 63 % reduction in the odds ratio of developing FN. CONCLUSIONS Incidence of FN with FEC-D treatment is considerably higher in clinical practice than reported in phase III trials. Consistent with ASCO guidelines, prophylactic G-CSF should be considered for all ESBC patients receiving adjuvant FEC-D.

Abstract
Although survival has improved among patients with acute leukemia, there is still a considerable risk of severe complications throughout the course of treatment. This contrast increases the interest in monitoring health related quality of life (HRQOL) in these patients. This study presents a longitudinal HRQOL evaluation (European Organisation for Research and Treatment of Cancer core 30-item questionnaire; EORTC-QLQ C-30) and the impact of infectious comorbidity among 60 patients with leukemia (median age 47) treated in an outpatient management program at Copenhagen University Hospital. Significant improvement was seen on several HRQOL scores during follow-up. Explorative general linear models (GLMs) suggest that high cumulative severity of infectious comorbidity significantly reduces physical functioning and overall quality of life at treatment completion.

Primary G-CSF prophylaxis for adjuvant TC or FEC-D chemotherapy outside of clinical trial settings: a systematic review and meta-analysis. Support Care Cancer 2012; 20:2523-30. [PMID: 22252548 DOI: 10.1007/s00520-011-1375-6] [Citation(s) in RCA: 39] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2011] [Accepted: 12/29/2011] [Indexed: 10/14/2022]
Abstract
BACKGROUND Variable febrile neutropenia (FN) rates reported with adjuvant TC (taxotere®, cyclophosphamide) and FEC-D (5-flurouracil, epirubicin, cyclophosphamide, docetaxel) outside of clinical trials have precluded definitive recommendations for primary G-CSF (granulocyte colony-stimulating factor) prophylaxis in most jurisdictions. A systematic review and meta-analysis was conducted to assess: (a) FN rates associated with TC and FEC-D without primary G-CSF prophylaxis outside of clinical trial settings, and (b) the potential impact of G-CSF prophylaxis on FN prevention. METHODS A MEDLINE search was conducted and major conference abstracts were reviewed up to June 15th 2011 to identify all relevant English-language studies. Random- and fixed-effects meta-analysis models were performed. RESULTS Nine hundred two patients treated with TC and 1342 with FEC-D from 13 to 9 studies, respectively, were included. The pooled random-effects meta-analysis estimates of FN rates for TC and FEC-D without G-CSF were 29% (95% CI 24-35%) and 31% (95% CI 27-35%), with a 76% (RR = 0.24, 95% CI 0.14-0.41) and 63% (RR = 0.37, 95% CI 0.11-1.24) relative risk reduction with G-CSF, respectively. CONCLUSION In routine clinical practice, TC and FEC-D without G-CSF are associated with FN rates exceeding the 20% threshold for which primary G-CSF prophylaxis is commonly recommended, and are considerably higher than those reported in pivotal clinical trials.
