Cancer-related inflammation affects many aspects of malignancy, including proliferation and survival of malignant cells, angiogenesis, and therapeutic response. Some biomarkers representing the degree of systemic inflammation, such as the Glasgow prognostic score, NLR and PLR, have been shown to have prognostic value in many kinds of cancer patients. Aim of this study to investigate to compare neutrophil/leukocyte (NLR) and platelet/lymphocyte (PLR) ratios of the patients with colorectal neoplastic polyps and colorectal cancer (CRC) and tried to determine whether this could be used as a biomarker in follow up of the patients with neoplastic polyps.A total of 100 colorectal polyps, 113 colorectal cancers and 124 healthy controls were included in the study. Exculusion criteria were endocrinologic or metabolic diseases, acute or chronic diseases, hypertension and atherosclerotic heart diseases, renal diseases. Blood count parameters of the patients were measured. The NLR was calculated as a simple ratio between the absolute neutrophil and the absolute lymphocyte counts. The PLR was defined as the platelet counts to lymphocyte ratio.A statistically significant difference was not detected between Group A and C with regard to NLR and PLR. NLR and PLR were found statistically significantly high in Group B (CRC), Group A (colorectal polyp) and Group C (healthy individuals) (p0.001 and p0.001). Our study showed that the optimum NLR cut-off point for neoplastic polyps was 2.28 (sensitivity: 68.7%, specificity: 42.3%). When the sensitivity and specificity levels of the PLR were assessed, they were 68.7% and 46.5% for neoplastic polyps, 80% and 68.9% for colorectal cancer.NLR and PLR may be used for follow up conversion of colonic and rectal neoplastic polyps to invasive tumor. |
