About this trial
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.
