Tumor grade is an important factor of cancer outcome. Systematic inflammation has been associated with tumorigenesis and tumor aggressiveness and prognosis in several human malignancies. Cancer cells create an inflammatory peritumoral microenviroment by releasing a number of cytokines.
In total, 100 patients (88 males) with histologically proven NSCLC and no signs of active infection were evaluated. Tumor grade was examined and systematic inflammatory response was assessed by circulating levels of C-reactive protein (CRP), albumin, ferritin, transferring and the modified Glasgow Prognostic Score (mGPS). Patients were followed up and survival data were subsequently collected. Associations with clinicopathological, histological parameters and patients’ survival were studied.
Histological grade was associated with tumor size, the presence of pathological lymph nodes, organ metastases and advanced disease stage (p = 0.010, p
Our data support the association of tumour grade with the presence of systemic inflammation; two well described negative prognostic factors for NSCLC. To our knowledge this is the first time that these factors are associated with each other giving more information about the prognosis in patients with NSCLC.
