Inmunoregulatory cytokines may play a fundamental role in tumor growth and metastases. Since the control of cytokine production is highly complex and multifactorial, their effects are mediated through multiple regulatory networks. This indicates that the definition and evaluation of a human cytokine profile represents an important future tool to analyze the interaction network of cytokines and thus identify patients' subgroups with different prognosis and also new potential biomarkers in therapeutic strategies particularly in immunotherapy approach.The aim of this study was to assess the clinical usefulness of data mining profile of multiple cytokines in advance Non-Small Cell Lung Cancer (NSCLC).


We conducted a prospective analysis of 15 inmunoregulatory cytokines plasma levels by ELISA and Cytometric Bead Array Assay of 110 NSCLC patients and 25 control subjects. Cytokine levels as well as data mining profiles were associated with clinical, pathological and prognostic characteristics.


NSCLC patients had higher levels of IL6, IL-18, IL-12p70, IL-17A and IFN-g and lower levels of IL-33 and IL-29 compared to controls. Pro-inflammatory cytokines such as IL-1b, IL-6 and IL-8 were associated with lower hemoglobin levels, worse performance status (ECOG), fatigue and hyporexia. Anti- inflammatory cytokines such as IL-4, IL-10 y IL-33 was associated with anorexia and lower body mass index. A 10-fold cross-validation EM algorithm found three clusters of patients regarding the plasma levels of cytokines levels without clinical differences between them.


Our results provide evidence that cytokines profiles may identify patients' subgroups with poor prognosis. Data mining clusters may play a role in the physiopathology of NSCLC and as a potential multiple biomarkers and targeted immunotherapy.
