Abstract
BACKGROUND Febrile neutropenia (FN) is a relatively common complication of cytotoxic chemotherapy. Prophylaxis with granulocyte colony-stimulating factor (G-CSF) can prevent FN and chemotherapy dose delays and enable the use of the higher dose intensities associated with a survival benefit; however, G‑CSF is not always used optimally. Five medical oncologists with a special interest in supportive care met to discuss the evidence for prophylaxis with G‑CSF to improve survival in cancer patients, identify reasons why this is not always done, and suggest potential solutions. The dose intensity of chemotherapy is critical for maximizing survival in cancer patients but may be reduced as a result of hematological toxicity, such as FN. Use of G‑CSF has been shown to increase the chances of achieving the planned dose intensity in various cancers, including early-stage breast cancer and non-Hodgkin lymphoma. All physicians treating cancer patients should consider the use of G‑CSF prophylaxis in patients receiving chemotherapy, paying particular attention to patient-related risk factors. KEY MESSAGES Strategies to optimize G‑CSF use include educating medical oncologists and pharmacists on the appropriate use of G‑CSF and informing patients about the efficacy of G‑CSF and its potential adverse effects. It is hoped that the evidence and opinions presented will help to encourage appropriate use of G‑CSF to support cancer patients at risk of FN in achieving the best possible outcomes from chemotherapy.

Abstract
PURPOSE Myelosuppressive chemotherapy-induced neutropenia (CIN) remains a major limitation of cancer treatment efficacy, necessitating very expensive supportive care. Lithium carbonate, an inexpensive drug, can increase the number of neutrophils, possibly providing an efficacious and cost-effective alternative for treating CIN. The aim of this study was to determine whether lithium therapy can attenuate chemotherapy-induced neutropenia and leukopenia in breast cancer patients. METHODS A total of 50 breast cancer patients were enrolled in this prospective, interventional, randomized, controlled, and single-blind study. The patients were divided into two groups: a control group (group 1, N = 25 patients) and a lithium-treated (treatment) group (group 2, N = 25 patients). Group 1 patients were further subclassified into a non-neutropenic control group (N = 16) and a neutropenic control (N = 9) based on the subsequent development of severe neutropenia, or not. The control group received 4 cycles of doxorubicin or epirubicin plus cyclophosphamide followed by 2 cycles of paclitaxel. The treatment group received the same regimen as the control group as well as oral lithium carbonate throughout the chemotherapy cycles. RESULTS The results showed that the absolute neutrophil count (ANC) was increased in the lithium-treated group, while it was markedly reduced in both the non-neutropenic and neutropenic control groups (by 55.56% and 65.42% post-4 chemotherapy cycles, and by 19.57% and 39.90% post-6 cycles, respectively). The same pattern of alterations was observed for the total white blood cell count in both the control and treatment groups. In addition, the incidence and period prevalence were greatly reduced in the lithium-treated group compared to non-neutropenic and neutropenic control groups. CONCLUSION Lithium therapy ameliorated chemotherapy-induced leukopenia and neutropenia in breast cancer patients. This may provide a new strategy for cost-effective treatment of CIN, particularly in Egyptian cancer patients.

Abstract
INTRODUCTION The Ohio State University Comprehensive Cancer Center (The James) uses daily subcutaneous filgrastim as the inpatient granulocyte colony-stimulating factor of choice. The coordination of care associated with filgrastim can often be a barrier to patient discharge. The purpose of this study was to compare the inpatient cost of daily filgrastim to single dose pegfilgrastim and biosimilars. METHODS Adult patients admitted to The James who received at least one dose of filgrastim between June 1, 2021 and August 31, 2021 were retrospectively identified. This study compared the inpatient cost of filgrastim and biosimilars associated with one chemotherapy cycle to the potential inpatient cost of pegfilgrastim and biosimilars based on average sales price (ASP). Additionally, the number and duration of discharge prescriptions for filgrastim was determined. RESULTS Of the 44 unique patient encounters that met inclusion criteria, 19 received 300-mcg doses of filgrastim and 25 received 480-mcg doses. The median number of doses administered per admission was eight. If each of these patients were to instead receive the most inexpensive biosimilar, pegfilgrastim reference product, the cost would be 216% higher than with filgrastim-sndz. At discharge, 15 patients (34%) received a prescription for filgrastim to be continued for a median duration of 6 days. CONCLUSION Based on ASP, pegfilgrastim was more costly than filgrastim. Potential rebates and negotiation power may alter the financial outlook of adding pegfilgrastim to inpatient formulary. Exploration of delays in discharge due to insurance coordination for filgrastim continuation in the outpatient setting may also impact formulary decisions.

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.

Abstract
Chemotherapy, radiotherapy, targeted therapy, and immunotherapy have brought hope to cancer patients. With the prolongation of survival of cancer patients and increased clinical experience, cancer-therapy-induced cardiovascular toxicity has attracted attention. The adverse effects of cancer therapy that can lead to life-threatening or induce long-term morbidity require rational approaches to prevention and treatment, which requires deeper understanding of the molecular biology underpinning the disease. In addition to the drugs used widely for cardio-protection, traditional Chinese medicine (TCM) formulations are also efficacious and can be expected to achieve “personalized treatment” from multiple perspectives. Moreover, the increased prevalence of cancer in patients with cardiovascular disease has spurred the development of “reverse cardio-oncology”, which underscores the urgency of collaboration between cardiologists and oncologists. This review summarizes the mechanisms by which cancer therapy induces cardiovascular toxicity, the combination of antineoplastic and cardioprotective drugs, and recent advances in reverse cardio-oncology.

Abstract
BACKGROUND Changes in the incidence of bleomycin pulmonary toxicity (BPT) as a result of adding colony-stimulating factors (CSF) to bleomycin regimens has been investigated in numerous studies. We performed a systematic review and meta-analysis to assess the outcomes of these studies. METHODS A systematic search was performed using Pubmed, Scopus, Web of Science, and Embase on April 2021. Studies evaluating the incidence of BPT in patients receiving bleomycin with and without CSF were included. In addition, meta-analysis was performed by pooling odds ratios using R. RESULTS Out of 340 obtained records, our qualitative and quantitative analysis included 3234 and 1956 patients from 22 and 14 studies, respectively. The quantitative synthesis showed that addition of CSF significantly increased the risk of BPT incidence (OR = 1.82, 95 % CI: 1.37-2.40, p < 0.0001; I2 = 10.7 %). Subgroup analysis did not show any association between continent, bleomycin dose, cancer type, type of study, and pulmonary function test with BPT incidence. CONCLUSION This systematic review and meta-analysis showed that co-administration of CSF with bleomycin increases the incidence of BPT. The physicians need to consider this finding while deciding the best strategy for this cohort of patients.

Assessment of Safety and Immunogenicity of MHC homozygous iPSC-derived CD34+ Hematopoietic Progenitors in a NHP Model. Blood Adv 2022; 6:5267-5278.

Abstract
Infusion of iHPs is safe and well tolerated in NHPs. iHPs are hypoimmunogenic and can be administered with a low risk of alloimmunization.
Administration of ex vivo expanded somatic myeloid progenitors has been explored as a way to facilitate a more rapid myeloid recovery and improve overall survival after myeloablation. Recent advances in induced pluripotent stem cell (iPSC) technologies have created alternative platforms for supplying off-the-shelf immunologically compatible myeloid progenitors, including cellular products derived from major histocompatibility complex (MHC) homozygous superdonors, potentially increasing the availability of MHC-matching cells and maximizing the utility of stem cell banking. However, the teratogenic and tumorigenic potential of iPSC-derived progenitor cells and whether they will induce alloreactive antibodies upon transfer remain unclear. We evaluated the safety and efficacy of using CD34+CD45+ hematopoietic progenitors derived from MHC homozygous iPSCs (iHPs) to treat cytopenia after myeloablative hematopoietic stem cell (HSC) transplantation in a Mauritian cynomolgus macaque (MCM) nonhuman primate (NHP) model. We demonstrated that infusion of iHPs was well tolerated and safe, observing no teratomas or tumors in the MCMs up to 1 year after HSC transplantation and iHP infusion. Importantly, the iHPs also did not induce significant levels of alloantibodies in MHC-matched or -mismatched immunocompetent MCMs, even after increasing MHC expression on iHPs with interferon-γ. These results support the feasibility of iHP use in the setting of myeloablation and suggest that iHP products pose a low risk of inducing alloreactive antibodies.

Abstract
PURPOSE The anti-CD33 antibody lintuzumab has modest activity against acute myeloid leukemia (AML). To increase its potency, lintuzumab was conjugated to actinium-225 (225Ac), a radionuclide yielding 4 α-particles. This first-in-human, phase I trial was conducted to determine the safety, pharmacology, and biological activity of 225Ac-lintuzumab. PATIENTS AND METHODS Eighteen patients (median age, 64 years; range, 45-80) with relapsed or refractory AML received a single infusion of 225Ac-lintuzumab at activities of 18.5-148 kBq/kg. RESULTS The maximum tolerated dose was 111 kBq/kg. Dose-limiting toxicities included myelosuppression lasting > 35 days in one patient receiving 148 kBq/kg and death from sepsis in two patients treated with 111 and 148 kBq/kg. Myelosuppression was the most common toxicity. Significant extramedullary toxicities were limited to transient grade 3 liver function abnormalities. Pharmacokinetics were determined by gamma counting serial whole blood, plasma, and urine samples at energy windows for the 225Ac daughters, francium-221 and bismuth-213. Two-phase elimination kinetics were seen with mean plasma t1/2-α and t1/2-β of 1.9 and 38 hours, respectively. Peripheral blood blasts were eliminated in 10 of 16 evaluable patients (63%) but only at doses of {greater than or equal to} 37 kBq/kg. Bone marrow blasts were reduced in 10 of 15 evaluable patients (67%), including 3 patients with marrow blasts {less than or equal to} 5% and 1 patient with a morphologic leukemia-free state. CONCLUSIONS Therapy for AML with the targeted α-particle generator 225Ac-lintuzumab was feasible with an acceptable safety profile. Elimination of circulating blasts or reductions in marrow blasts were observed across all dose levels.

Abstract
Methotrexate (MTX) is an effective, economical and safe drug used in the treatment of ectopic pregnancy. Complications are very rare. Herein, we reported a case of febrile neutropenia following single low-dose methotrexate for the treatment of ectopic pregnancy. Febrile neutropenia developed on day 4 of single-dose methotrexate administered intramuscularly. Although methotrexate single-dose regimen is quite effective and safe in ectopic pregnancy, febrile neutropenia can occur very rarely.

Abstract
BACKGROUND To evaluate the efficacy and safety of recombinant human serum albumin /granulocyte colony-stimulating factor (rHSA/G-CSF) in breast cancer following receipt of cytotoxic agents. METHODS The phase 1b trial assessed the pharmacokinetics, pharmacodynamics, and safety of dose-escalation, ranging from rHSA/G-CSF 1800 μg, 2100 μg, and 2400 μg. Randomized controlled phase 2b trial was further conducted to ensure the comparative efficacy and safety of rHSA/G-CSF 2400 μg and rhG-CSF 5 μg/kg. In multicenter, randomized, open-label, parallel, phase 2 study, participants treated with anthracycline-containing chemotherapy were assigned in a ratio 1:1:1 to receive double delivery of rHSA/G-CSF 1200 μg, 1500 μg, and continuous rhG-CSF 5 μg/kg. RESULTS Between December 16, 2014, to July 23, 2018, a total of 320 patients were enrolled, including 25 individuals in phase 1b trial, 80 patients in phase 2b trial, and 215 participants in phase 2 study. The mean duration of agranulocytosis during the first chemotherapeutic intermission was observed as 1.14 ± 1.35 days in rHSA/G-CSF 1500 μg, which was comparable with that of 1.07 ± 0.97 days obtained in rhG-CSF control (P = 0.71). Safety profiles were assessed to be acceptable ranging from rHSA/G-CSF 1800 μg to 2400 μg, while the double delivery of HSA/G-CSF 2400 μg failed to meet the noninferiority in comparison with rhG-CSF. CONCLUSION The prospective randomized controlled trials demonstrated that rHSA/G-CSF was efficacious and well-tolerated with an approachable frequency and expense of application for prophylactic management of agranulocytosis. The double delivery of rHSA/G-CSF 1500 μg in comparisons with paralleling G-CSF preparations is warranted in the phase 3 trial. TRIAL REGISTRATION ClinicalTrials.gov identifiers: NCT02465801 (11/17/2014), NCT03246009 (08/08/2017), NCT03251768 (08/07/2017).

Salako O, Okunade KS, Adeniji AA, Fagbenro GT, Afolaranmi OJ. Chemotherapy induced neutropenia and febrile neutropenia among breast cancer patients in a tertiary hospital in Nigeria. Ecancermedicalscience 2021; 15:1188. [PMID: 33777181 PMCID: PMC7987487 DOI: 10.3332/ecancer.2021.1188] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2020] [Indexed: 11/23/2022] Open
Abstract
Purpose This study assessed the incidence of chemotherapy-induced neutropenia and febrile neutropenia (FN) while identifying their associated factors. Methods A prospective cross-sectional study was conducted among 113 female chemotherapy-naïve breast cancer patients over a 2-year period. Socio-demographic, clinical and haematological data were obtained via semi-structured interviews and from medical case files. Blood samples for complete blood count parameters were collected 2 weeks after each course of chemotherapy. The National Cancer Institute Common Terminology Criteria for Adverse Events version 4.03 was used to assess FN, neutropenia and their severity. Results The incidence of neutropenia and FN among the patients was 31.9% and 5.3%, respectively. Throughout all courses of chemotherapy (n = 502), there were 57 (11.4%) neutropenic episodes with 6.6% mild, 3.4% moderate and 1.4% severe neutropenia. The incidence of neutropenia decreased with increasing chemotherapy courses, with a rate of 14.2% and 4.9% after the first and last course, respectively. Factors associated with the risk of developing neutropenia include increasing age (p = 0.014), Eastern Cooperative Oncology Group performance score ≥ 1 at presentation (p = 0.033) and presence of bone metastasis (p = 0.002). Conclusion One in three breast cancer patients in this study developed neutropenia while on chemotherapy but no independent risk factors were identified for FN among these patients. This study has, therefore, provided the preliminary data necessary for further independent validation of the identified risk factors for FN in a more robust and well-designed study within our clinical practice setting in Nigeria.

Abstract
Filgrastim is a granulocyte-colony stimulating factors (G-CSF) used for multiple indications in cancer patients. We present a case of a 65-year-old man with non-Hodgkin’s lymphoma who was undergoing mobilization of hemopoietic stem cells for autologous-hematopoietic stem cell transplantation (auto-HSCT) with filgrastim who developed dyspnea and non-productive cough. Chest imaging showed left lower lobe consolidation, new ground-glass opacities and small right-sided pleural effusion. Bronchoscopy with bronchoalveolar lavage (BAL) and infectious evaluation were completely negative. He was admitted for further evaluation and management. Antibiotics weren’t started immediately given the clinical stability, multiple probable causes of fever and the intent of not confounding future thoracentesis results with antibiotic use. Thoracentesis occurred draining serous exudative pleural fluid; with follow-up chest imaging demonstrating no re-accumulation. His symptoms resolved and he was discharged in stable condition. The symptoms were hypothesized to be the probable adverse effects of filgrastim. We suggest close monitoring of pulmonary toxicities while administering this drug to patients to minimize such complications.

Abstract
OBJECTIVE To study the pharmacokinetic characteristics, clinical effect, and safety of pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) in children with acute lymphoblastic leukemia (ALL). METHODS A prospective study was performed on children with ALL who cyclophosphamide, cytarabine, and 6-mercaptopurine were used for consolidation therapy. PEG-rhG-CSF (PEG-rhG-CSF group) or rhG-CSF (rhG-CSF group) was injected after chemotherapy. The plasma concentration of PEG-rhG-CSF was measured, and clinical outcome and safety were observed for both groups. RESULTS A total of 17 children with ALL were enrolled, with 9 children in the PEG-rhG-CSF group and 8 children in the rhG-CSF group. In the PEG-rhG-CSF group, the peak concentration of PEG-rhG-CSF was 348.2 ng/mL (range 114.7-552.0 ng/mL), the time to peak was 48 hours (range 12-72 hours), and the half life was 14.1 hours (range 11.1-18.1 hours). The plasma concentration curve of PEG-rhG-CSF was consistent with the mechanism of neutrophil-mediated clearance. Compared with the rhG-CSF group, the PEG-rhG-CSF group had a significantly shorter median time to absolute neutrophil count (ANC) recovery (P<0.05). There were no significant differences between the two groups in ANC nadir, incidence rate of febrile neutropenia, duration of grade IV neutropenia, incidence rate of infection, and length of hospital stay. No bone pain or muscle soreness was observed in either group (P>0.05). CONCLUSIONS The pharmacokinetic characteristics of PEG-rhG-CSF in children with ALL receiving consolidation chemotherapy are consistent with the mechanism of neutrophil-mediated clearance, with a short half life and fast recovery of ANC, and there are no significant differences in safety between PEG-rhG-CSF and rhG-CSF.

Abstract
Febrile neutropenia (FEN) is a significant side effect after chemotherapy, and it is known that using granulocyte colony-stimulating factor (G-CSF) has positive effects on treatment results. In this study, the effects of different G-CSF doses (5 to 10 mcg/kg/day) on treatment results in patients with high-risk FEN were evaluated. A total of 124 high-risk FEN episodes of 62 patients were enrolled in the study between June 2017 and October 2018. The episodes were divided into 2 groups according to G-CSF treatment doses, they received from 5 to 10 mcg/kg/day. The clinical characteristics of the patients, the treatments they received, laboratory findings, microbiologic results, and cost analysis were recorded. No statistically significant difference was found between 2 groups in terms of the mean duration of recovery from neutropenia, duration of fever, total length of hospital stay, duration of FEN episode, duration of G-CSF use, costs, bacteremia frequency, and other treatments. In patients with solid tumors, the cost of filgrastim was significantly higher in the high-dose G-CSF group. Using different doses of G-CSF in high-risk FEN episodes did not show any different effects on clinical and treatment results. The dose of 5 mcg/kg/day would be more appropriate in FEN treatment.

Abstract
Silver nanoparticles are among the most significant diagnostic and therapeutic agents in the field of nanomedicines. In the current study, the green chemistry approach was made to optimize a cost-effective synthesis protocol for silver nanoparticles from the aqueous extract of the important anticancer plant Fagonia indica. We investigated the anticancer potential and possible involvement of AgNPs in apoptosis. The biosynthesized AgNPs are stable (zeta potential, -16.3 mV) and spherical with a crystal size range from 10 to 60 nm. The MTT cell viability assay shows concentration-dependent inhibition of the growth of Michigan Cancer Foundation-7 (MCF-7) cells (IC50, 12.35 μg/mL). In addition, the fluorescent microscopic analysis shows activation of caspases 3 and 9 by AgNPs that cause morphological changes (AO/EB assay) in the cell membrane and cause nuclear condensation (DAPI assay) that eventually lead to apoptotic cell death (Annexin V/PI assay). It was also observed that AgNPs generate reactive oxygen species (ROS) that modulate oxidative stress in MCF-7 cells. This is the first study that reports the synthesis of a silver nanoparticle mediated by Fagonia indica extract and evaluation of the cellular and molecular mechanism of apoptosis.

Abstract
Neutropenia is the most frequent side effect of commercially available myelosuppressive drugs and its most significant complication is febrile neutropenia. It is associated with increased hospital admissions and higher probability of death. Prophylaxis with the administration of granulocyte colony-stimulating factor can prevent neutropenia caused by anticancer drugs. The correct administration of these drugs and the management of febrile neutropenia are extremely important in the treatment of patients with cancer.

Abstract
Filgrastim prophylaxis, both primary and secondary, was rapidly incorporated into clinical practice in the 1990s. When pegfilgrastim became available in 2002, it quickly replaced filgrastim as the colony-stimulating factor (CSF) of choice for prophylaxis. Use of prophylaxis increased markedly in the first decade of this century and has stabilized during the present decade. Data concerning real-world CSF prophylactic practice patterns are limited but suggest that both primary and secondary prophylaxis are common, and that use is frequently inappropriate according to guidelines. The extent of inappropriate use is controversial, as are issues concerning the cost-effectiveness of prophylaxis versus no prophylaxis and the cost-effectiveness of primary prophylaxis versus secondary prophylaxis. Nevertheless, CSF prophylaxis is firmly established as a valuable adjunct to chemotherapy and will almost certainly continue to be widely used for the foreseeable future. In this article, we chronicle the use and impact of CSF prophylaxis in US patients receiving myelosuppressive chemotherapy for non-myeloid malignancies. We emphasize the interplay of expert opinion, clinical evidence, and economic factors in shaping the use of CSFs in clinical practice over time, and, with the recent introduction of new CSF agents and options, we aim to provide useful clinical and economic information for healthcare decision makers.

Abstract
Hematopoiesis is a dynamic process of the continuous production of diverse blood cell types to meet the body's physiological demands and involves complex regulation of multiple cellular mechanisms in hematopoietic stem cells, including proliferation, self-renewal, differentiation, and apoptosis. Disruption of the hematopoietic system is known to cause various hematological disorders such as myelosuppression. There is growing evidence on the beneficial effects of herbal medicines on hematopoiesis; however, their mechanism of action remains unclear. In this study, we conducted a network pharmacological-based investigation of the system-level mechanisms underlying the hematopoietic activity of Samul-tang, which is an herbal formula consisting of four herbal medicines, including Angelicae Gigantis Radix, Rehmanniae Radix Preparata, Paeoniae Radix Alba, and Cnidii Rhizoma. In silico analysis of the absorption-distribution-metabolism-excretion model identified 16 active phytochemical compounds contained in Samul-tang that may target 158 genes/proteins associated with myelosuppression to exert pharmacological effects. Functional enrichment analysis suggested that the targets of Samul-tang were significantly enriched in multiple pathways closely related to the hematopoiesis and myelosuppression development, including the PI3K-Akt, MAPK, IL-17, TNF, FoxO, HIF-1, NF-kappa B, and p53 signaling pathways. Our study provides novel evidence regarding the system-level mechanisms underlying the hematopoiesis-promoting effect of herbal medicines for hematological disorder treatment.

Abstract
Chemotherapy-Induced Leukopenia (CIL) is associated with increased mortality and economic burden on patients. This study was conducted to evaluate whether inclusion of green jackfruit flour in regular diet of those patients receiving chemotherapy, could prevent CIL. This was a retrospective study conducted among a group of patients undergoing chemotherapy for solid tumors at Renai Medicity Hospital, Palarivattom, Cochin, Kerala, India, since June 2018. The study group comprised of 50 consecutive subjects, who were supplemented with green jackfruit flour diet in their regular diet and further followed up prospectively. The control group was retrospective with 50 subjects prior to June 2018, with no diet supplements. Those who received less than three cycles were excluded from either arm. The mean age of the participants in study group and control group were 53.16 ± 11.06 and 56.96 ± 12.16 years respectively. In the study group, six patients out of 37, and 20 patients out of 50 in the control group, developed CIL. They received 38 and 105 vials of filgrastim respectively. After excluding those cycles in study group patients, where green jackfruit flour was not taken, the mean number of cycles in which CIL developed (p = 0.00) and number of vials of filgrastim taken per cycle (p = 0.00) were significantly different from control group and no patient in the study group developed CIL. Inclusion of green jackfruit flour as a dietary intervention prevents chemotherapy-induced leukopenia in patients undergoing chemotherapy along with pegfilgrastim.

Abstract
For better management of patients with febrile neutropenia, our study investigated the epidemiologic, microbiologic, and clinical characteristics of adult inpatients with febrile neutropenia and their mortality-associated factors. To this end, we carried out a prospective, observational, multicenter study in 28 Argentinian hospitals between 2007 and 2012. We included 515 episodes of febrile neutropenia from 346 patients, median age 49 years. Neutropenia followed chemotherapy in 77% of cases, half of the cases due to hematological malignancies. Most episodes were classified as high-risk according to MASCC criteria, and 53.6% of patients were already hospitalized at the onset of febrile neutropenia. Bloodstream infections were detected in 14% episodes; whereas an infectious source of fever was identified in 80% of cases. Mortality rate achieved to 14.95%. The binary regression analysis showed that persistence of fever at day 7, or neutropenia at day 14, dehydration and tachycardia at the onset of febrile neutropenia as well as prior infections were significantly associated with mortality. In addition to expanding our current knowledge on the features of adult patients with febrile neutropenia, present findings provide useful information for better management of them in Argentina, given the appropriate representativeness of centers participating in the study.

Abstract
AIM Neutropenia is a common side effect of myelosuppressive chemotherapy. Administration of granulocyte colony-stimulating factor is being used for neutropenia prophylaxis, but there are patients who develop neutropenia or febrile neutropenia despite prophylaxis. We attempted to identify potential risk factors for chemotherapy-induced neutropenia in patients with pegfilgrastim prophylaxis. METHODS This was a single-center, retrospective, observational study of patients with breast cancer or diffuse large B-cell lymphoma. We obtained patients' data from electronic medical records, including baseline demographics and clinical characteristics regarding diseases, treatments and laboratory values. The outcome measures assessed were the incidence of neutropenia and febrile neutropenia. RESULTS There were a total of 127 patients, including 77 patients with diffuse large B-cell lymphoma (DLBCL) and 50 patients with breast cancer, and we analyzed 722 chemotherapy cycles. We found 88 cases (12.2%) of grade 3 or 4 neutropenia and 39 cases of febrile neutropenia (5.4%). In the univariate analysis, variables associated with both grade 3 or 4 neutropenia and febrile neutropenia were age, cancer type, cancer stage, radiotherapy and platelet count. A multivariate logistic regression model revealed that age, radiotherapy and platelet count were significant factors in severe neutropenia, whereas platelet count was the only statistically significant factor in febrile neutropenia. Platelet counts of less than 150 000/mm3 increased the risk of neutropenia and febrile neutropenia approximately fourfold. In the subgroup analysis of patients with DLBCL, it was found that platelet count was a significant factor for both neutropenia and febrile neutropenia. CONCLUSION Among cancer patients with pegfilgrastim prophylaxis, advanced age, absence of radiation therapy and low platelet count were independent predictors of neutropenia, and low platelet count was the predictor of febrile neutropenia.

Abstract
BACKGROUND Standard treatment for untreated advanced-stage follicular lymphoma is rituximab plus chemotherapy. The incidence of histological transformation of follicular lymphoma has been reported only in heterogeneously treated populations and rarely with long-term follow-up. Additionally, the incidence of secondary malignancies after treatment, without high-dose therapy for follicular lymphoma, is largely unknown. The aim of our study was to assess progression-free survival, overall survival, incidence of secondary malignancies, and incidence of histological transformation in a 10-year follow-up analysis of the JCOG0203 trial. METHODS In the phase 2-3 randomised JCOG0203 trial, previously untreated patients with stage III or IV indolent B-cell lymphoma, including grades 1-3 follicular lymphoma, from 44 hospital centres in Japan, were randomly assigned (1:1) by use of a minimisation method to receive six cycles of R-CHOP (rituximab [375 mg/m2], given on day 1, plus cyclophosphamide [750 mg/m2], doxorubicin [50 mg/m2], vincristine [1·4 mg/m2, capped at 2·0 mg] given intravenously on day 3, and oral prednisone [100 mg once daily on days 3-7]) every 3 weeks (R-CHOP-21) or every 2 weeks (enabled by mandatory granulocyte-colony stimulating factor administration once daily for 6 days, starting on day 8; R-CHOP-14) without rituximab maintenance. Age, bulky disease (nodal or extranodal mass ≥10 cm in diameter on CT), and institution were used as adjustment factors. Investigators enrolled participants, and assignment to trial groups was done with a computer-assisted randomisation allocation sequence that took place centrally at the Japan Clinical Oncology Group Data Center, without the intervention of investigators. Interventions were not masked for patients or investigators. Data were collected 10 years after enrolment of the last patient. The primary endpoint of the phase 3 part of the study was progression-free survival, and the primary endpoint of the phase 2 part of the study was the proportion of patients who achieved a complete response. Accrual was 4·5 years, and follow-up was 3 years after registration was closed. Data were updated on the cutoff date of Feb 28, 2017. Intention-to-treat analyses (ie, progression-free survival, overall survival, and incidence of secondary malignancies) were predefined, to be done at 10 years after the last patient was enrolled. An additional analysis of the incidence of histological transformation was defined 15 years after the protocol, on May 8, 2017, in a supplementary analysis plan, and assessed at 10 years after the last patient was enrolled. Follow-up is ongoing. This trial is registered with ClinicalTrials.gov, number NCT00147121. FINDINGS Between Sept 1, 2002, and Feb 28, 2007, 300 patients were enrolled, and 149 (50%) were assigned to the R-CHOP-21 group and 151 (50%) were assigned to the R-CHOP-14 group. After eligibility was assessed, one patient was excluded from the R-CHOP-21 group. 10-year progression-free survival was not different between groups (R-CHOP-21 33%, 95% CI 25-41; R-CHOP-14 39%, 31-47; hazard ratio 0·89, 95% CI 0·67-1·17). In 248 patients with grade 1-3a follicular lymphoma, progression-free survival was 39% (33-45) at 8 years and 36% (30-42) at 10 years. The cumulative incidence of histological transformation was 3·2% (95% CI 1·5-6·0) at 5 years, 8·5% (5·4-12·4) at 8 years, and 9·3% (6·1-13·4) at 10 years after enrolment. At 10 years, the cumulative incidence of secondary malignancies was 8·1% (5·1-12·0) and the cumulative incidence of haematological secondary malignancies was 2·9% (1·3-5·5). INTERPRETATION R-CHOP is a viable option for first-line treatment in patients with newly diagnosed advanced follicular lymphoma. Clinicians choosing a first-line treatment for patients with follicular lymphoma should be cautious of secondary malignancies caused by immunochemotherapy and severe complications of infectious diseases in the long-term follow-up-both of which could lead to death.

Abstract
Aims and background The addition of oxaliplatin to the widely employed De Gramont schedule (FOLFOX regimen) in patients with metastatic colorectal cancer improved their outcome with a moderate toxicity pattern. The adaptation of the delivery rate of 5-fluorouracil, leucovorin and oxaliplatin to circadian rhythms (chronotherapy) resulted in a very high drug tolerability with clinical results at least comparable to those achieved with the FOLFOX regimen. However, chronomodulated infusion seemed to be more expensive, requiring dedicated electronic pumps and several disposable materials. The present study aimed to compare the direct costs of the two regimens and to determine whether chronotherapy was effectively more expensive than the FOLFOX regimen. Study design The direct costs of drug delivery devices derived from various publicly available sources and of toxicity management as extrapolated from two published studies considering comparable patient subsets were added and compared. Results Pump, central venous system and disposable materials for a single chronotherapy cycle were € 193 or € 212 according to whether the pumps were bought or rented, compared to € 58 for the FOLFOX regimen. Toxicity management costs were € 144 vs € 288 for the two schemes, respectively. Globally, a single course of chronotherapy cost € 337 or € 356, whereas a single FOLFOX cycle cost € 346. Conclusions Direct costs for a single chronotherapy cycle appeared to be comparable to a single course of the FOLFOX regimen. In fact, the major material cost of chronochemotherapy devices was balanced by a better tolerability profile. The overall improvement in quality of life with chronochemotherapy affecting indirect costs, such as reduction of work, and intangible costs is worthy of further pharmacoeconomic attention.

Abstract
Myeloid-derived suppressor cells (MDSCs) have a strong immunosuppressive character that allows them to regulate immune responses and hinder overt inflammatory responses. In cancer, this leads to tumor immune evasion and disease progression. MDSCs come in at least two forms: monocytic (Mo-MDSCs) and granulocytic (G-MDSCs). The classical definition of MDSCs as immature myeloid cells blocked from differentiating has been challenged by recent studies suggesting that Mo-MDSCs and G-MDSCs may represent monocytes and granulocytes that have acquired immunosuppressive properties. The molecular mechanism behind their generation and their true origins are now widely debated. In this review we discuss the different proposed mechanisms of the generation of both types of MDSCs, with a special focus on human MDSCs in cancer.

Abstract
PURPOSE The purpose of this study is to assess temporal trends in the use of granulocyte colony-stimulating factor (G-CSF) prophylaxis and risk of febrile neutropenia (FN) among older women receiving adjuvant chemotherapy for early-stage breast cancer. METHODS Women aged ≥ 66 years with diagnosis of early-stage breast cancer who initiated selected adjuvant chemotherapy regimens were identified using the SEER-Medicare data from 2002 to 2012. Adjusted, calendar-year-specific proportions were estimated for use of G-CSF primary prophylaxis (PP) and secondary prophylaxis and FN risk in the first and the second/subsequent cycles during the first course of chemotherapy, using logistic regression models. calendar-year-specific mean probabilities were estimated with covariates set to modal values. RESULTS Among 11,107 eligible patients (mean age 71.7 years), 74% received G-CSF in the first course of chemotherapy. Of all patients, 5819 (52%) received G-CSF PP, and among those not receiving G-CSF PP, only 5% received G-CSF secondary prophylaxis. The adjusted proportion using G-CSF PP increased from 6% in 2002 to 71% in 2012. During the same period, the adjusted risk of FN in the first cycle increased from 2% to 3%; the adjusted risk increased from 1.5% to 2.9% among those receiving G-CSF PP and from 2.3% to 3.5% among those not receiving G-CSF PP. CONCLUSION The use of G-CSF PP increased substantially during the study period. Although channeling of higher-risk patients to treatment with G-CSF PP is expected, the adjusted risk of FN among patients treated with G-CSF PP tended to be lower than among those not receiving G-CSF PP.

Abstract
BACKGROUND The management of elderly patients with cancer is influenced by several factors that can vary widely among aging individuals. As the proportion of elderly individuals increases, the need for specific care guidelines for this population is critical. The National Comprehensive Cancer Network (NCCN) has developed guidelines to address these factors when formulating optimal treatment regimens for elderly patients and to avoid significant toxicity and maintain their quality of life. METHODS Factors that influence the appropriate treatment choices for the elderly, such as functional status, comorbidity, polypharmacy, and the presence of anemia, are reviewed, and the guidelines developed by the NCCN for treatment elderly patients are discussed. RESULTS The guidelines address these factors when defining the goal of therapy and formulating individualized treatment approaches for the elderly to provide optimal care for these patients, avoid significant toxicity, and maintain their quality of life. CONCLUSIONS The goal of therapy must be clearly defined, whether survival, remission, cure, or palliation of symptoms. Enrollment of elderly cancer patients onto clinical trials is encouraged so the guidelines can be validated.

Abstract
Radix Sanguisorbae, the root of Sanguisorba officinalis L. is used as traditional Chinese medicine. In recent decades, it has been reported to be clinically effective against myelosuppression induced by chemotherapy and/ or radiotherapy. However, the underlining mechanism has not been well studied. In this work, we evaluated the hematopoietic effect of total saponins from S. officinalis L. on myelosuppressive mice induced by cyclophosphamide and by60Co-γ-irradiation and confirmed the therapeutic effect. Then, we found total saponins and their characteristic constituents Ziyuglycoside I and Ziyuglycoside II can inhibit apoptosis of TF-1 cells caused by cytokine deprivation, and promote survival of mouse bone marrow nuclear cells through focal adhesion kinase (FAK) and extracellular signal-regulated kinase 1/2 (Erk1/2) activation in vitro. In addition, they can down-regulate macrophage inflammatory protein 2 (MIP-2), platelet factor 4 (PF4) and P-selectin secretion, which are reported to be suppressive to hematopoiesis, both in vitro and in vivo. These results suggest that promotion of survival through FAK and Erk1/2 activation and inhibition of suppressive cytokines in the bone marrow is likely to be the pharmacological mechanism underlying the hematopoietic effect of saponins from S. officinalis L.

Abstract
Objective The recommended dose of prophylactic pegylated recombinant human granulocyte-colony stimulating factor (PEG rhG-CSF) is 100 μg/kg once per cycle for patients receiving intense-dose chemotherapy. However, few data are available on the proper dose for patients receiving less-intense chemotherapy. The aim of this phase I study is to explore the proper dose and administration schedule of PEG rhG-CSF for patients receiving standard-dose chemotherapy. Methods Eligible patients received 3-cycle chemotherapy every 3 weeks. No PEG rhG-CSF was given in the first cycle. Patients experienced grade 3 or 4 neutropenia would then enter the cycle 2 and 3. In cycle 2, patients received a single subcutaneous injection of prophylactic PEG rhG-CSF on d 3, and received half-dose subcutaneous injection in cycle 3 on d 3 and d 5, respectively. Escalating doses (30, 60, 100 and 200 μg/kg) of PEG rhG-CSF were investigated. Results A total of 26 patients were enrolled and received chemotherapy, in which 24 and 18 patients entered cycle 2 and cycle 3 treatment, respectively. In cycle 2, the incidence of grade 3 or 4 neutropenia for patients receiving single-dose PEG rhG-CSF of 30, 60, 100 and 200 μg/kg was 66.67%, 33.33%, 22.22% and 0, respectively, with a median duration less than 1 (0-2) d. No grade 3 or higher neutropenia was noted in cycle 3 in all dose cohorts. Conclusions The pharmacokinetic and pharmacodynamic profiles of PEG rhG-CSF used in cancer patients were similar to those reported, as well as the safety. Double half dose administration model showed better efficacy result than a single dose model in terms of grade 3 neutropenia and above. The single dose of 60 μg/kg, 100 μg/kg and double half dose of 30 μg/kg were recommended to the phase II study, hoping to find a preferable method for neutropenia treatment.

Uncaria tomentosa extract alters the catabolism of adenine nucleotides and expression of ecto-5'-nucleotidase/CD73 and P2X7 and A1 receptors in the MDA-MB-231 cell line. JOURNAL OF ETHNOPHARMACOLOGY 2016; 194:108-116. [PMID: 27590731 DOI: 10.1016/j.jep.2016.08.051] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/28/2016] [Revised: 08/22/2016] [Accepted: 08/30/2016] [Indexed: 06/06/2023]
Abstract
ETHOPHARMACOLOGICAL RELEVANCE Uncaria tomentosa (Willd.) DC. (Rubiaceae) (Ut), also known as cat's claw, is a woody liana widely spread throughout the Amazon rainforest of Central and South America, containing many chemical constituents such as oxindole alkaloids, which are responsible for various biological activities. Since ancient times, the indigenous people of Peru have used it as a bark infusion for the treatment of a wide range of health problems gastric ulcers, arthritis and rheumatism. Recently, Ut is distributed worldwide and used as an immunomodulatory and anti-inflammatory herbal remedy. Additionally, U. tomentosa also has antitumural activity. However, little is known about the action of U. tomentosa on the purinergic system mechanisms, which is involved in tumor progression. AIM OF THE STUDY Considering the pharmacological properties of U. tomentosa, we sought to evaluate the hydroalcoholic extract U tomentosa is able to influence the purinergic system in breast cancer cells, MDA-MB-231. Through the activity and expression of ectonucleotidases (NTPDase - CD39; Ecto-5'-nucleotidase - CD73) and purinergic repceptores (P2X7 and A1). MATERIALS AND METHODS A hydroalcoholic extract was prepared in two concentrations, 250 and 500μg/mL. (Ut250; Ut500). The effect of these concentrations on the activity and expression of ectonucleotidases, as well as on the density of purinergic receptors were investigated in MDA-MB-231 breast cancer cells. Cells were treated with the hydroalcoholic extract of Uncaria tomentosa and/or doxorubicin (Doxo 1μM; Ut250+Doxo; Ut500+Doxo) for 24h. RESULTS Although the results were not significant for the hydrolysis of the ATP, they presented an increase in the ADP hydrolysis in the Ut500+Doxo group when compared to the control group. Additionally, the activity of 5'-nucleotidase was inhibited in all groups when compared with the untreated group of cells. Inhibition of the enzyme was more evident in groups with U. tomentosa per se. The expression of CD39 was increased in the Ut250 and Ut250+Doxo groups when compared to the control group. No changes were found in the CD73 expression. Furthermore, a reduction in the density of the P2X7 receptor in all treated groups was detected. On the other hand, the density of the A1 receptor increased in all groups compared to the control group, with the exception of the Ut500+Doxo group. CONCLUSION Therefore, we conclude that hydroalcoholic extract of U. tomentosa may be responsible for the reduction of adenosine levels in the extracellular medium, which accelerates tumor progression. Interestingly, the dysregulation of A1 and P2X7 receptors in the MDA-MB-231 cells exacerbate the proliferation of this cells and U. tomentosa treatment may be stimulate the antitumor activity of adenosine A1 receptor and control the P2X7 effects. Our study demonstrates the significant participation of purinergic pathway in the regulation of MDA-MB-231 progression; additionally, U. tomentosa treatment alone or combined with chemotherapy may favor the action of doxorubicin.

Abstract
Patterns of myeloid growth factor (GF) usage and febrile neutropenia (FN) were examined in patients >60 years of age with diffuse large B-cell non-Hodgkin lymphoma (DLBCL) enrolled on CALGB 9793/ECOG-SWOG 4494, receiving initial therapy with cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP) or rituximab + CHOP (R-CHOP). Myeloid GFs were administered to 256/520 (49%) patients. Indications for use were: prevent dose reduction/dose delay (81%, 207/256); treat FN or non-febrile neutropenia (NFN) (19%, 48/256). One or more FN episodes occurred in 41% (212/520) of patients, with FN most often in cycle 1 (38% of episodes). In multivariate analysis, risk factors for FN included age >65 years (odds ratio (OR) = 2.6, 95% CI: [1.4, 4.9]) and anemia (hemoglobin <12 g/dl) (OR =2.2, 95% confidence intervals (CI): [1.4, 3.5]. Myeloid GF use was common in this older DLBCL population receiving CHOP-based therapy, as was FN, especially during cycle one. Risk factors predictive for FN should be used prospectively to identify patients for whom myeloid GFs are best utilized.

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
Chemotherapy-induced neutropenia (CIN) is the major dose-limiting toxicity of systemic chemotherapy and it is associated with significant morbidity, mortality and treatment cost. The aim of the present study was to identify the risk factors that may predispose pediatric cancer patients who receive myelosuppressive chemotherapy to CIN and associated sequelae. A total of 113 neutropenia episodes were analyzed and the risk factors for CIN were classified as patient-specific, disease-specific and regimen-specific, while the consequences of CIN were divided into infectious and dose-modifying sequelae. The risks and consequences were analyzed to target high-risk patients with appropriate preventive strategies. Among our patients, 28% presented with a single neutropenia attack, while 72% experienced recurrent attacks during their treatment cycles. The mean absolute neutrophil count was 225.5±128.5 ×109/l (range, 10-497 ×109/l), starting 14.2±16.3 days (range, 2-100 days) after the onset of chemotherapy and resolving within 11.2±7.3 days, either with (45.1%) or without (54.9%) granulocyte colony-stimulating factor (G-CSF). No significant association was observed between any patient characteristics or disease stage and the risk for CIN. However, certain malignancies, such as acute lymphocytic leukemia (ALL), neuroblastoma and Burkitt's lymphoma, and certain regimens, such as induction block for ALL and acute myelocytic leukemia, exerted the most potent myelotoxic effect, with severe and prolonged episodes of neutropenia. G-CSF significantly shortened the duration of the episodes and enhanced bone marrow recovery. Febrile neutropenia was the leading complication among our cases (73.5%) and was associated with several documented infections, particularly mucositis (54.9%), respiratory (45.1%), gastrointestinal tract (38.9%) and skin (23.9%) infections. A total of 6% of our patients succumbed to infection-related complications. Neutropenia was responsible for treatment discontinuation (13.3%), dose delay (13.3%) and dose reduction (5.3%) in our patients. The mean cost for each episode in our institution was 9,386.5±6,688.9 Egyptian pounds, which represented a significant burden on health care providers.

Melatonin, an inhibitory agent in breast cancer. Breast Cancer 2016; 24:42-51. [PMID: 27017208 DOI: 10.1007/s12282-016-0690-7] [Citation(s) in RCA: 63] [Impact Index Per Article: 7.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2015] [Accepted: 03/15/2016] [Indexed: 12/22/2022]
Abstract
BACKGROUND The heterogeneous nature of breast cancer makes it one of the most challenging cancers to treat. Due to the stimulatory effect of estrogen in mammary cancer progression, anti-estrogenic agents like melatonin have found their way into breast cancer treatment. Further studies confirmed a reverse correlation between nocturnal melatonin levels and the development of mammary cancer. In this study we reviewed the molecular inhibitory effects of melatonin in breast cancer therapy. METHODS To open access the articles, Google scholar and science direct were used as a motor search. We used from valid external and internal databases. To reach the search formula, we determined mean key words like breast cancer, melatonin, cell proliferation and death. To retrieval the related articles, we continuously search the articles from 1984 to 2015. The relevance and the quality of the 480 articles were screened; at least we selected 80 eligible articles about melatonin molecular mechanism in breast cancer. RESULT The results showed that melatonin not only inhibits breast cancer cell growth, but also is capable of inhibiting angiogenesis, cancer cell invasion, and telomerase activity. Interestingly this hormone is able to induce apoptosis through the suppression or induction of a wide range of signaling pathways. Moreover, it seems that the concomitant administration of melatonin with other conventional chemotherapy agents had beneficial effects for patients with breast cancer, by alleviating unfavorable effects of those agents and enhancing their efficacy. CONCLUSION The broad inhibitory effects of melatonin in breast cancer make it a promising agent and may add it to the list of potential drugs in treatment of this cancer.

Abstract
BACKGROUND Metastatic breast cancer (MBC) remains a devastating and incurable disease. Over the past decade, the implementation of clinical trials both with and without molecular targeted therapeutics has impacted the daily clinical treatment of patients with MBC. In this study, we determine whether including MBC patients in clinical trials affects clinical outcomes. METHODS We retrospectively reviewed data for a total of 863 patients diagnosed with initial or recurrent (after receiving adjuvant systemic treatments following surgery) metastatic disease between January 2000 and December 2013. Data were obtained from the breast cancer database of Samsung Medical Center. RESULTS Among the 806 patients selected for inclusion, 188 (23%) had participated in clinical trials. A total of 185 clinical trials were conducted from 2000 to 2014. When compared with earlier periods (n = 10 for 2000-2004), clinical trial enrollment significantly increased over time (n = 103 for 2005-2009, P = 0.024; n = 110 for 2010-2014, P = 0.046). Multivariate analyses revealed that biologic subtype, distant recurrence free interval (DRFI), and clinical trial enrollment were independent predictors of overall survival. Patients who participated in clinical trials showed improved survival, with a hazard ratio of 0.75 (95% CI, 0.59-0.95), which was associated with a 25% reduction in the risk of death. However, subgroup analysis showed that this improved survival benefit was not maintained in patients with triple negative breast cancer (TNBC). CONCLUSIONS Although not conclusive, we could speculate that there were differences in the use of newer agents or regimens over time, and these differences appear to be associated with improved survival.

Abstract
Advances in chemotherapy and surgery allows the majority of patients to survive cancer diseases. Yet, the price may be a proportion of patients dying of complications due to treatment-induced infectious complications, such as neutropenia. With the aim of decreasing morbidity and mortality related to infectious complications, recombinant human granulocyte colony-stimulating factor (G-CSF), filgrastim, and pegylated filgrastim have been used to reduce time and degree of neutropenia. A biosimilar is a copy of an approved original biologic medicine whose data protection has expired. The patent for filgrastim expired in Europe in 2006 and in the US in 2013. This review analyses the available evidence to be considered in order to design a strategy of use of G-CSF and its biosimilars. The clinical and safety outcomes of biosimilars are well within the range of historically reported data for originator filgrastim. This underscores the clinical effectiveness and safety of biosimilar filgrastim in daily clinical practice. Biosimilars can play an important role by offering the opportunity to reduce costs, thus contributing to the financial sustainability of treatment programs.

Abstract
BACKGROUND It is important for pharmacists to manage cancer chemotherapy regimens in order to achieve safe treatment. We examined whether there was a useful pharmacoeconomic benefit of compliance the exclusion criteria of neutropenia, and the importance of a pharmacist's intervention was considered. METHODS A prospective observational cohort study was conducted at a community-based medical center. Among 374 patients who received chemotherapy between April 2010 and March 2011, 108 patients developed neutropenia and pharmacists recommended suspension of chemotherapy. These patients were divided into a group in whom chemotherapy was suspended (complying group) and a group in whom it was continued (non-complying group). Then the relative dose intensity (RDI) was compared between the two groups, and medical expenses related to the treatment of neutropenia (neutropenia-related costs: NRC) were compared. Analysis was carried out from the perspective of the health insurance provider, so only the direct medical costs were evaluated. RESULTS There was a significant difference of the RDI between a complying group (85.2 ± 10.0%) and a non-complying group (79.3 ± 15.0%) (P = 0.021). The average NRC per patient showed a significant difference between the two groups (complying group: 1,944 ± 412 dollars, non-complying group: 4,394 ± 837 dollars, P = 0.044). The economic effect over one year was 54,205 dollars. CONCLUSION The present findings suggest that ensuring compliance with chemotherapy regimens (including the criteria for neutropenia) is effective from a pharmacoeconomic perspective. Accordingly, pharmacists should intervene as required to improve regimen compliance.

Abstract
Cytotoxic chemotherapy remains the first-line therapy for many advanced solid tumors; hence, understanding the underlying mechanisms to overcome chemoresistance remains a top research priority. In the clinic, chemotherapy is administered in multiple cycles that are spaced out to allow the recovery or repopulation of normal tissues and tissue stem cells between treatment cycles. However, residual surviving cancer cells and cancer stem cells can also repopulate tumors during the gap periods between chemotherapy cycles. Tumor repopulation is a phenomenon that has not been well studied; it is often overlooked due to current customized experimental study strategies. Recent findings reveal an alarming role for dying cells targeted by chemotherapy in releasing mitogens to stimulate active repopulation of quiescent cancer stem cells. Therefore, new therapeutic options to abrogate tumor repopulation will provide new avenues to improve chemotherapeutic response and clinical outcome.

Abstract
OBJECTIVES This study aimed to evaluate the efficacy and safety of once-per-cycle balugrastim versus pegfilgrastim for neutrophil support in breast cancer patients receiving myelosuppressive chemotherapy. METHODS Breast cancer patients (n = 256) were randomized to 40 or 50 mg of subcutaneous balugrastim or 6 mg of pegfilgrastim ≈24 hours after chemotherapy (60 mg/m(2) doxorubicin and 75 mg/m(2) docetaxel, every 21 days for up to 4 cycles). The primary efficacy parameter was the duration of severe neutropenia (DSN) in cycle 1. Secondary parameters included DSN (cycles 2-4), absolute neutrophil count (ANC) nadir, febrile neutropenia rates, and time to ANC recovery (cycles 1-4). Safety, pharmacokinetics, and immunogenicity were assessed. RESULTS Mean cycle 1 DSN was 1.0 day with 40 mg of balugrastim, 1.3 with 50 mg of balugrastim, and 1.2 with pegfilgrastim (upper limit of 95% confidence intervals for between-group DSN differences was <1.0 day for both balugrastim doses versus pegfilgrastim). Between-group efficacy parameters were comparable except for time to ANC recovery in cycle 1 (40 mg of balugrastim, 2.0 days; 50 mg of balugrastim, 2.1; pegfilgrastim, 2.6). Median terminal elimination half-life was ≈37 hours for 40 mg of balugrastim, ≈36 for 50 mg of balugrastim, and ≈45 for pegfilgrastim. Antibody response to balugrastim was low and transient, with no neutralizing effect. CONCLUSION Once-per-cycle balugrastim is not inferior to pegfilgrastim in reducing cycle 1 DSN in breast cancer patients receiving chemotherapy; both drugs have comparable safety profiles. IMPLICATIONS FOR PRACTICE This paper provides efficacy and safety data for a new, once-per-cycle granulocyte colony-stimulating factor, balugrastim, for the prevention of chemotherapy-induced neutropenia in patients with breast cancer receiving myelosuppressive chemotherapy. In this phase III trial, balugrastim was shown to be not inferior to pegfilgrastim in the duration of severe neutropenia in cycle 1 of doxorubicin/docetaxel chemotherapy, and the safety profiles of the two agents were similar. Once-per-cycle balugrastim is a safe and effective alternative to pegfilgrastim for hematopoietic support in patients with breast cancer receiving myelosuppressive chemotherapy associated with a greater than 20% risk of developing febrile neutropenia.

Abstract
G-CSF and GM-CSF are used widely to promote the production of granulocytes or APCs. The U.S. Food and Drug Administration approved G-CSF (filgrastim) for the treatment of congenital and acquired neutropenias and for mobilization of peripheral hematopoietic progenitor cells for stem cell transplantation. A polyethylene glycol-modified form of G-CSF is approved for the treatment of neutropenias. Clinically significant neutropenia, rendering an individual immunocompromised, occurs when their number is <1500/μl. Current guidelines recommend their use when the risk for febrile neutropenia is >20%. GM-CSF (sargramostim) is approved for neutropenia associated with stem cell transplantation. Because of its promotion of APC function, GM-CSF is being evaluated as an immunostimulatory adjuvant in a number of clinical trials. More than 20 million persons have benefited worldwide, and >$5 billion in sales occur annually in the United States.

Abstract
INTRODUCTION Treatment impact on quality of life (QoL) informs treatment management decisions in advanced nonsquamous non-small-cell lung cancer (NS NSCLC). QoL outcomes from the phase III PointBreak trial are reported. METHODS Chemonaive patients (n = 939) with stage IIIB/IV nonsquamous non-small-cell lung cancer and Eastern Cooperative Oncology Group performance status 0 to 1 were randomized (1:1) to pemetrexed-carboplatin-bevacizumab (pemetrexed arm) or paclitaxel-carboplatin-bevacizumab (paclitaxel arm). Patients without progressive disease received maintenance pemetrexed-bevacizumab (pemetrexed arm) or bevacizumab (paclitaxel arm). QoL was assessed using Functional Assessment of Cancer Therapy (FACT)-General (FACT-G), FACT-Lung (FACT-L), and FACT/Gynecologic Oncology Group-Neurotoxicity (FACT-Ntx) instruments. Subscale scores, total scores, and trial outcome indices were analyzed using linear mixed-effects models. Post hoc analyses examined the association between baseline FACT scores and overall survival (OS). RESULTS Mean score differences in change from baseline significantly favored the pemetrexed arm for the neurotoxicity subscale score, FACT-Ntx total scores, and FACT-Ntx trial outcome index. They occurred at cycle 2 (p < 0.001) and persisted through induction cycles 2 to 4 and six maintenance cycles. Investigator-assessed, qualitative, drug-related differences in grade 2 (1.6% versus 10.6%) and grade 3 (0.0% versus 4.1%) sensory neuropathy and grade 3/4 fatigue (10.9% versus 5.0%, p = 0.0012) were observed between the pemetrexed and paclitaxel arms. Baseline FACT-G, FACT-L, and FACT-Ntx scores were significant prognostic factors for OS (p < 0.001). CONCLUSIONS Randomized patients reported similar changes in QoL, except for less change from baseline in neurotoxicity on the pemetrexed arm; investigators reported greater neurotoxicity on the paclitaxel arm and greater fatigue on the pemetrexed arm. Higher baseline FACT scores were favorable prognostic factors for OS.
