Effect of G-CSF on MDSC and Cancer Stem-cells Interactions in Non-small Cell Lung Cancers (CIRCUIT)

Immunotherapy have revolutionized the field of oncology, but response rates are low and all patients relapse, due to immunologic (myeloid immunosuppressive cells) and non-immunologic (cancer stem- cells (CSC)) mechanisms. CSC are able to circulate within blood, protected from destruction by immunosuppressive cells such as MDSC. Some factors such as G-CSF, administered to lower febrile neutropenia, should modulate properties of MDSC and CSC, but data are contradictory, and literature remain poor regarding its effects on the interactions between MDSC and CSC in blood clusters. Indeed, this project aims at better characterizing the effect of G-CSF on these interactions and on their functions in NSCLC patients receiving G-CSF.

Outcomes of Early and Late Administration G-CSF for Primary Prophylaxis in Non-Hodgkin's Lymphoma Patients

The goal of this clinical trial is to Primary Objectives: 1. To compare the incidence of febrile neutropenia in patients with non-Hodgkin's lymphoma who received early or late granulocyte colony-stimulating factor (G-CSF) during standard chemotherapy in a multicenter study 2. To determine the incidence of leukopenia and neutropenia in patients with non-Hodgkin's lymphoma who received early or late G-CSF during standard chemotherapy in a multicenter study Secondary Objectives: 1. To determine changes in white blood cell, hemoglobin, and platelet levels in patients with non-Hodgkin's lymphoma who received early or late G-CSF during standard chemotherapy. 2. To determine the quality of life of patients with non-Hodgkin's lymphoma who undergoing standard chemotherapy and with neutropenia Researchers will compare the outcome between patients received either early G-CSF (within 72 hours) or late G-CSF (after 72 hours). All patients will be followed up to monitor for febrile neutropenia events, other hematological parameters and quality of life.
