Therefore,G-CSF,which acts as a neutrophil growth factor, can be administered immediately after chemotherapy to increase the production rate of neutrophils and promote the efflux of mature neutrophils from the bone marrow, thereby increasing the absolute neutrophil count. Guidelines for the use of G-CSF published by the NCCN indicate that primary prophylaxis with G-CSF has clinical benefit for patients receiving anticancer drug therapy with a risk of febrile neutropenia greater than 20%. For those at 10-20% risk, consider primary prophylaxis based on risk factors. The frequency of neutropenic fever with FOLFIRINOX chemotherapy, which is commonly used in patients with locally advanced or metastatic pancreatic cancer, was 5.4% in a prospective study of patients receiving high-dose regimens, but 42.5% of patients received prophylactic G-CSF, and 63.0% of patients received prophylactic G-CSF compared to 3.0% when given as postoperative adjuvant therapy demonstrating the need for G-CSF administration.In a retrospective study in Japan, a modified FOLFIRINOX chemotherapy regimen without pegylated G-CSF was associated with a 23% incidence of neutropenic fever and 61.5% grade 3-4 neutropenia, while prophylactic administration of pegylated G-CSF was associated with zero neutropenic fever and grade 3-4 neutropenia and longer survival .A retrospective study from Korea also reported that prophylactic G-CSF administration reduced neutropenic fever from 18.5% to 1.8% and Grade 3-4 neutropenia from 55.6% to 31.6 in pancreatic cancer patients receiving FOLFIRINOX .Pegteograstim (Neulapeg®) is a pegylated human recombinant granulocyte colony-stimulating factor with a long half-life (15-80 hours) compared to filgrastim (3-4 hours). Although several studies have demonstrated that G-CSF primary prophylaxis reduces the frequency of hematologic toxicities, particularly febrile neutropenia, during chemotherapy, it has not been prospectively studied whether primary prophylaxis reduces the frequency of grade 3-4 neutropenia and neutropenic fever in the modified FOLFIRINOX chemotherapy regimen in patients with pancreatic cancer. Therefore, this study is designed to determine if prophylactic administration of NEURAPEC reduces the frequency of Grade 3-4 neutropenia and neutropenic fever in patients with locally advanced or metastatic pancreatic cancer receiving modified FOLFIRINOX chemotherapy. conditions: Locally Advanced Pancreatic Cancer conditions: Metastatic Pancreatic Cancer studyType: INTERVENTIONAL phases: PHASE2 allocation: RANDOMIZED interventionModel: CROSSOVER primaryPurpose: PREVENTION masking: NONE count: 78 type: ACTUAL name: Neulapeg name: Control measure: Development of grade 3-4 neutropenia (grade 3-4 neutropenia, ANC<1000/mL) measure: development of neutropenic fever (febrile neutropenia) measure: relative dose intensity measure: quality of life assessed according to EORTC QLQ-C30 measure: Number of patients experiencing Adverse events (AEs) measure: objective response rate measure: Progression-free survival measure: Overall survival measure: Change in blood cytokine concentrations measure: G-CSF induced bone pain as assessed by questionnaires sex: ALL minimumAge: 19 Years stdAges: ADULT stdAges: OLDER_ADULT facility: Severance Hospital city: Seoul country: Korea, Republic of lat: 37.566 lon: 126.9784 hasResults: False
