Serum levels of IL-1β, IL-2, IL-4, IL-13 and IFN-γ vary over the course of chemotherapy. Serum levels of 10 cytokines were measured at each time point using a commercially available magnetic bead-based Bio-Plex Human Cytokine Panel 10-Plex Assay. Assay was performed in triplicate and bars represent the cytokine levels for 24 enrolled patients stratified by cytokine (a) or draw (b), displayed as mean ± SEM
