Korean J Intern Med 2021; 36:1181-1189. [PMID: 34265889 PMCID: PMC8435507 DOI: 10.3904/kjim.2020.206] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2020] [Accepted: 10/29/2020] [Indexed: 11/27/2022] Open
Abstract
BACKGROUND/AIMS Febrile neutropenia (FN) interferes with the proper chemotherapy dose density or intensity in non-Hodgkin's lymphoma (NHL) patients. Chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) ± rituximab has an intermediate FN risk. Prophylactic granulocyte colony-stimulating factor (G-CSF) support is recommended for patients with other host-related risk factors. METHODS We evaluated the risk factors for FN-related admission in NHL patients who have received primary G-CSF (lenograstim) prophylaxis. RESULTS Data from 148 patients were analyzed. The incidence of neutropenic fever was 96 events (12.2%), and the median period was 3.85 days (range, 0 to 5.9); the median duration of neutropenia was 4.21 days (range, 3.3 to 5.07). Eighty-three FN-related admissions were reported. Advanced age (> 60 years), female sex, a low albumin level, and prednisone use were associated with FN-related admission in multivariable analysis (p = 0.010, p < 0.001, and p = 0.010, respectively). A comparison between diffuse large B-cell lymphoma patients treated with R-CHOP and pegylated G-CSF and those treated with R-CHOP and lenograstim did not reveal significant differences in the FN-related admission rate between the two groups, although the lenograstim-treated group had a higher incidence of severe neutropenia. CONCLUSION Elderly patients, female patients, and patients with low albumin levels need to be actively followed-up for FN even when primary prophylaxis with G-CSF has been used.

Prophylactic pegfilgrastim to prevent febrile neutropenia among patients receiving biweekly (Q2W) chemotherapy regimens: a systematic review of efficacy, effectiveness and safety. BMC Cancer 2021; 21:621. [PMID: 34044798 PMCID: PMC8157684 DOI: 10.1186/s12885-021-08258-w] [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: 08/11/2020] [Accepted: 04/26/2021] [Indexed: 01/01/2023] Open
Abstract
Background Pegfilgrastim, a long-acting granulocyte colony-stimulating factor (G-CSF), is commonly used to prevent febrile neutropenia (FN), a potentially life-threatening complication, following myelosuppressive chemotherapy. The FDA label for pegfilgrastim specifies that it should not be administered 14 days before or within 24 h of administration of myelosuppressive chemotherapy, precluding the use of pegfilgrastim in biweekly (Q2W) regimens. The National Comprehensive Cancer Network and the European Organisation for Research and Treatment of Cancer guidelines support the use of prophylactic pegfilgrastim in patients receiving Q2W regimens. The objective of this study was to systematically review evidence from randomized clinical trials (RCTs) and observational studies that describe the effectiveness and safety of prophylactic pegfilgrastim in preventing FN among patients receiving Q2W regimens. Methods An Ovid MEDLINE, Embase, and Cochrane Library literature search was conducted to evaluate the evidence regarding efficacy, effectiveness, and safety of prophylactic pegfilgrastim versus no prophylactic pegfilgrastim or prophylaxis with other G-CSF in patients who were receiving Q2W chemotherapy regimens with high (> 20%) or intermediate (10–20%) risk of FN for a non-myeloid malignancy. Studies that addressed absolute or relative risk of FN, grade 1–4 neutropenia, all-cause or any hospitalization, dose delays or dose reductions, adverse events, or mortality were included. Studies where the comparator was a Q3W chemotherapy regimen with primary prophylactic pegfilgrastim were also included. Results The initial literature search identified 2258 publications. Thirteen publications met the eligibility criteria, including eight retrospective, one prospective, one phase 1 dose escalation study, and three RCTs. In nine of the 13 studies reporting incidence of FN, and in seven of the nine studies reporting incidence of neutropenia, administration of prophylactic pegfilgrastim in patients receiving Q2W regimens resulted in decreased or comparable rates of FN or neutropenia compared with patients receiving filgrastim, no G-CSF, lipefilgrastim or pegfilgrastim in Q3W regimens. In six of the nine studies reporting safety data, lower or comparable safety profiles were observed between pegfilgrastim and comparators. Conclusions In a variety of non-myeloid malignancies, administration of prophylactic pegfilgrastim was efficacious in reducing the risk of FN in patients receiving high- or intermediate-risk Q2W regimens, with an acceptable safety profile.

Abstract
Background This study aimed to evaluate the efficacy and the safety of polyethylene glycol conjugated granulocyte colony-stimulating factor (PEG-G-CSF) for preventing neutropenia in metastatic colorectal cancer (mCRC) patients that received fluorouracil, leucovorin, oxaliplatin, and irinotecan (FOLFOXIRI) plus bevacizumab (Bev) in clinical practice. Methods We retrospectively analyzed mCRC patients who received FOLFOXIRI plus Bev between December 2015 and December 2017. We evaluated the efficacy of PEG-G-CSF as preventing or treating grade 3 or 4 neutropenia, the overall response rate (ORR) according to the Response Evaluation Criteria in Solid Tumors version 1.1, progression-free survival (PFS), overall survival (OS), and adverse events of FOLFOXIRI plus Bev based on the Common Terminology Criteria for Adverse Events version 4.0. Results A total of 26 patients (median age 53.5 years) were included. The ORR rate was 65.3%, the median PFS was 9.6 months (7.2–16.9), and the median OS was 24.2 months (13.6–NA). Grade 3 or 4 neutropenia occurred in 53.8% of the patients, and febrile neutropenia occurred in 7.7%. PEG-G-CSF was given to 77.0% of the patients, including prophylactically (n = 9) and after the development of grade 3 or 4 neutropenia (n = 11). No patients experienced grade 3 or 4 neutropenia after the administration of PEG-G-CSF. In seven of the nine patients who received PEG-G-CSF prophylactically (77.8%), no dose adjustment was required. Conclusions PEG-G-CSF is useful in preventing severe neutropenia in mCRC patients treated with FOLFOXIRI plus Bev.

Cardiovascular adverse events in patients with non-Hodgkin lymphoma treated with first-line cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or CHOP with rituximab (R-CHOP): a systematic review and meta-analysis. LANCET HAEMATOLOGY 2020; 7:e295-e308. [PMID: 32135128 DOI: 10.1016/s2352-3026(20)30031-4] [Citation(s) in RCA: 36] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/21/2019] [Revised: 01/23/2020] [Accepted: 01/23/2020] [Indexed: 12/21/2022]
Abstract
BACKGROUND Patients treated for non-Hodgkin lymphoma are at risk of cardiovascular adverse events, with the risk of heart failure being particularly high. A regimen of cyclophosphamide, doxorubicin, vincristine, and prednisone, with (R-CHOP) or without (CHOP) rituximab is the standard first-line treatment for aggressive non-Hodgkin lymphoma, and doxorubicin and cyclophosphamide are both associated with left ventricular dysfunction. The aim of this systematic review and meta-analysis was to evaluate the cardiovascular toxicity of this regimen. METHODS We systematically searched PubMed, EMBASE, and the Cochrane Library from database inception to June 3, 2019, for clinical trials and observational studies in adult patients with non-Hodgkin lymphoma (diffuse large B-cell lymphoma, follicular lymphoma, mantle cell lymphoma, peripheral T-cell lymphoma, and non-Hodgkin lymphoma not otherwise specified) that received first-line treatment with R-CHOP or CHOP. Studies reporting on cardiovascular adverse events and treatment-related cardiovascular mortality were included. Abstracts and articles not written in English were excluded. The main outcomes were the proportion of patients with grade 3-4 cardiovascular adverse events and heart failure. Meta-analyses of one-sample proportions were done in all patients receiving CHOP or R-CHOP. Subgroup analyses on summary estimates were done to determine the effect of number of CHOP or R-CHOP cycles, cycle interval, age, and sex. FINDINGS Of 2314 identified entries, 137 studies (21 211 patients) published between April, 1984, and June, 2019 were eligible (9541 patients treated with CHOP, 11 293 patients treated with R-CHOP, 377 both regimens used in the study; median follow-up 39·0 months [IQR 25·5-52·8]). From the included studies, 85 subgroups were treated with CHOP, 76 with R-CHOP, and in four studies both CHOP and R-CHOP were used without a subdivision in separate groups. The pooled proportion for grade 3-4 cardiovascular adverse events, based on 77 studies (n=14 351 patients), was 2·35% (95% CI 1·81-2·93; heterogeneity test Q=326·21; τ2=0·0042; I2=71·40%; p<0·0001). For heart failure, the pooled proportion, based on 38 studies (n=5936 patients), was 4·62% (2·25-7·65; heterogeneity test Q=527·33; τ2=0·0384; I2=95·05%; p<0·0001), with a significant increase in reported heart failure from 1·64% (95% CI 0·82-2·65) to 11·72% (3·00-24·53) when cardiac function was evaluated post-chemotherapy (p=0·017). 53 (39%) of 137 studies were rated as having high risk of bias for incomplete outcome data and 54 (39%) for selective reporting. INTERPRETATION The considerable increase of reported heart failures with cardiac monitoring, indicates that this complication often remains undiagnosed in patients with non-Hodgkin lymphoma who received first-line R-CHOP or CHOP. Our findings are of importance to raise awareness of this complication among clinicians treating patients with non-Hodgkin lymphoma and stresses the need for cardiac monitoring during and after chemotherapy. Prompt initiation of treatment for heart failure in the presymptomatic phase can mitigate the progression to more advanced heart failure stages. FUNDING None.

Abstract
The optimum granulocyte colony-stimulating factor (G-CSF) treatment for cancer patients after being treated with cytotoxic chemotherapy remains unknown. Therefore, a systematic review and Bayesian network meta-analysis were performed to assess the efficacy and tolerability of 11 G-CSF drugs on patients after chemotherapy. A total of 73 randomized controlled trials (RCTs) containing 15,124 cancer patients were included for the final network meta-analysis. Compared with pegfilgrastim, there were a higher risk with filgrastim for incidence of febrile neutropenia (FN) (OR [95% CI]: 1.63 [1.07, 2.46]), and a higher risk with short-acting G-CSF (S-G-CSF) biosimilar and lenograstim for incidence of bone pain (BP) (OR [95% CI]: 6.45 [1.10, 65.73], 5.12 [1.14, 26.12], respectively). Mecapegfilgrastim, lipegfilgrastim and balugrastim were best G-CSF drugs in reducing FN (cumulative probabilities: 58%, 15%, 11%, respectively). S-G-CSF biosimilar, empegfilgrastim, and long-acting G-CSF (L-G-CSF) biosimilar were best G-CSF drugs in reducing severe neutropenia (SN) (cumulative probabilities: 21%, 20%, 15%, respectively). Mecapegfilgrastim, balugrastim, lipegfilgrastim and L-G-CSF biosimilar were best G-CSF drugs in reducing BP (cumulative probabilities: 20%, 14%, 8%, 8%, respectively). Mecapegfilgrastim, lipegfilgrastim and balugrastim might be the most appreciate G-CSF drugs with both good efficacy and tolerability when treating cancer patients after cytotoxic chemotherapy.

Systematic Review and Meta-analysis of Short- versus Long-Acting Granulocyte Colony-Stimulating Factors for Reduction of Chemotherapy-Induced Febrile Neutropenia. Adv Ther 2018; 35:1816-1829. [PMID: 30298233 PMCID: PMC6223993 DOI: 10.1007/s12325-018-0798-6] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2018] [Indexed: 11/26/2022]
Abstract
Introduction Short- and long-acting granulocyte-colony stimulating factors (G-CSFs) are approved for the reduction of febrile neutropenia. A systematic literature review was performed to identify randomized controlled trials (RCTs) and non-RCTs reporting the use of G-CSFs following chemotherapy treatment. Methods Medline®/Medline in-process, Embase®, and the Cochrane Library were searched for studies published between January 2003 and June 2016. A hand-search of relevant conference proceedings was conducted for meetings held between 2012 and 2016. Eligible studies were restricted to those reporting a direct, head-to-head comparison of short- versus long-acting G-CSFs for reduction of chemotherapy-induced febrile neutropenia. Risk-of-bias assessments were performed for full publications only. Results The search strategy yielded 4044 articles for electronic screening. Thirty-six publications were evaluated for the meta-analysis: 11 of 12 RCTs and 2 of 24 non-RCTs administered doses of the short-acting G-CSF filgrastim for ≥ 7 days. In RCT studies, there was no statistically significant difference in outcomes of interest between short- and long-acting G-CSFs. In non-RCTs, the overall risk was lower with long-acting G-CSF than with short-acting G-CSF for incidence of febrile neutropenia [overall relative risk (RR) = 0.67, P = 0.023], hospitalizations (overall RR = 0.68, P < 0.05), and chemotherapy dose delays (overall RR = 0.68, P = 0.020). Conclusions Overall, the weight of evidence from RCTs indicates little difference in efficacy between the short- and long-acting G-CSFs if dosed according to recommended guidelines. There is some evidence for greater efficacy for long-acting G-CSFs in non-RCTs, which may be a result of under-dosing of short-acting G-CSFs in general practice in real-world usage.
