Predictive Parameters of Febrile Neutropenia and Clinical Significance of G-CSF Receptor Signaling Pathway in the Development of Neutropenia during R-CHOP Chemotherapy with Prophylactic Pegfilgrastim in Patients with Diffuse Large B-Cell Lymphoma.

ABSTRACT:

Purpose

Pegfilgrastim is widely used to prevent chemotherapy-induced neutropenia (CIN) and febrile neutropenia (FN) in patients with diffuse large B-cell lymphoma (DLBCL). We investigated the predictive factors affecting CIN and FN incidence in patients with DLBCL receiving rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemotherapy with pegfilgrastim and conducted experiments to find reason for the occurrence of CIN even when pegfilgrastim was used.

Materials and methods

We reviewed the CIN and FN events of 200 patients with DLBCL. Based on these data, we investigate the association with predictive factor and the levels of granulocyte-colony stimulating factor (G-CSF) receptor signaling pathway markers (pSTAT3, pAKT, pERK1/2, pBAD, and CXCR4) in bone marrow (BM) samples isolated from patients with DLBCL.

Results

FN was significantly associated with stage III/IV (hazard ratio [HR], 12.74) and low serum albumin levels (HR, 3.87). Additionally, patients with FN had lower progression-free survival (PFS; 2-year PFS, 51.1 % vs. 74.0%) and overall survival (OS; 2-year OS, 58.2% vs. 85.0%) compared to those without FN. The occurrence of CIN was associated with overexpression of G-CSF receptor signaling pathway markers, and expression levels of these markers were upregulated in BM cells co-cultured with DLBCL cells. The rate of neutrophil apoptosis was also higher in neutrophils co-cultured with DLBCL cells and was further promoted by treatment with doxorubicin.

Conclusion

Our findings suggest that high DLBCL burden may alter the BM environment and G-CSF receptor signaling pathway, even in chemotherapy-naïve state, which may increase CIN frequency during R-CHOP chemotherapy.

Project description:BackgroundPegfilgrastim, 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.MethodsAn 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.ResultsThe 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.ConclusionsIn 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.Trial registrationPROSPERO registration no: CRD42019155572 .
