Cancer Risks and Factors

Abstract Objectives The aims of study were to assess platelet counts, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), RWD (red cells distribution width) and fasting glucose in patients with cervical intraepithelial neoplasia (CIN) and invasive cervical cancer; and to relate these parameters to prognostic factors and survival in cervical cancer. Study Design We evaluated the patients with confirmed diagnosis of invasive cervical cancer (n = 102), and CIN (n = 102). Histological type, NLR, PLR, RDW, platelets count, fasting glucose, staging, overall survival (OS), and disease-free survival (DFS) were evaluated. The results of laboratory parameters were assessed by Mann-Whitney test. A receiver operating characteristic (ROC) curve was used to determine the best cut-off values. Survival was verified by the Kaplan-Meyer method followed by the Gehan-Breslow test. Multivariate analysis was performed using Cox regression. The level of significance was less than 0.05. Results Comparing CIN and invasive malignancies, higher values of NLR, PLR, RDW and fasting glucose were found in cancer patients (p < 0.0001, p=0.011, p=0.0153 and p=0.0096, respectively). In cervical cancer, higher NLR and PLR values were found at stage II to IV when compared to stage I (p = 0.0066 and p=0.005, respectively). ROC curves were performed. In invasive neoplasms, the cut-off values for NLR and PLR in the comparison between stage I and greater than I were 4 and 165.45, respectively. For survival curves, there was lower OS and DFS in patients with NLR greater than 4 (p = 0.0004 and p=0.0153, respectively) and PLR greater than 165.45 (p = 0.0319 and p=0.0362, respectively). After multivariate analysis, only NLR remained as an independent factor in DFS (HR = 6.095, 95 % CI=1.120–33.177, p=0.037) and OS (HR = 4.522, 95 % CI=1.241–16.479, p=0.022) Conclusion Higher NLR is associated to lower OS and DFS in invasive uterine cervical neoplasia, and can be considered an independent factor of worse prognosis.
