Background:
Alterations in glucose metabolism and appetite stimulating hormones have been correlated with inflammation but there is little information on frequency and prognosis in newly diagnosed stage IV non-small cell lung cancer (NSCLC) This study objective was to identify associations of circulating biomarkers of glucose metabolism and inflammation with prognosis in pre-treatment sera from stage IV NSCLC patients selected for platinum doublet based chemotherapy.
Methods:
Pretreatment serum from 118 Pts with frontline stage IV NSCLC were evaluated with the Bio-Plex Pro Human Diabetes Assay panel (adiponectin, adipsin, c-peptide, ghrelin, gastrin inhibitory peptide (GIP), glucagon-like peptide-1 (GLP-1), glucagon, IL-6, insulin, leptin, Plasminogen activator inhibitor-1, resistin, TNFα, vistatin) and HSTCMAG-28SK | MILLIPLEX MAP Human High Sensitivity T Cell Panel - Immunology Multiplex Assay (Fractalkin, GM-CSF, IFNγ, IL-1 β, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL-10, IL-12 (p70), IL-13, IL-17A, IL-21, IL-23, ITAC, macrophage inflammatory protein (MIP)-1α, MIP-1β, MIP-3α, TNFα) on a FlexMAP 3D system (Luminex Corp.). Pts were treated with standard platinum doublets based chemotherapy. Associations of biomarkers with progression free and overall survival (PFS,OS) outcomes were assessed using multivariate Cox PH analyses.
Results:
Most patients had metabolic levels below the prognostic threshold. However, high levels of insulin, GIP, glucagon, visfatin, ghrelin, GLP-1 were significantly associated (p<0.05) with shorter PFS. Low levels of adipisin (deficiency of which is associated with obesity) was associated with shorter PFS (p=.0185). High levels of pro-inflammatory markers: ITAC, GM-CSF, Fratalkine, INF-ϒ, IL-12p70, IL-13, IL17A, IL-4, IL-23, IL8.4, MIP-α, MIP-1 were also associated with poor PFS (p<0.05) (See Table I for more details on select biomarkers) High levels of these endocrine markers (except insulin and GIP) were associated with shorter OS as were ITAC, GMCSF, IL12p70, IL-13, IL4, IL23, IL5 (p<0.05).

Conclusion:
Imbalances in the glucose metabolism pathway and increased levels of pro-inflammatory circulating markers were uncommon but consistently associated with a poor prognosis in stage IV NSCLC patients early in their treatment cycle. Alterations in these systems have been associated with cancer cachexia and may be targets for intervention in improving prognosis for select patients with NSCLC.
