Prognostic nutritional index (PNI), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII) are the most common factors to estimate nutritional and inflammatory status. The aim of this study is to systematically evaluate the prognostic significance of above nutritional and inflammatory indexes for overall survival (OS) and surgical complications in esophageal cancer patients.Esophageal cancer patients who underwent esophagectomy were retrospectively collected. PNI, NLR, PLR, and SII were introduced to evaluate the baseline nutritional and inflammatory status.A total of 407 patients were included in the present study. Kaplan-Meier survival analysis revealed that PNI-low group, NLR-high group and PLR-high group, all showed a significantly shorter OS (34.38% vs 49.46%, P < 0.001; 36.13% vs 48.26%, P = 0.026 and 33.33% vs 48.52%, P = 0.001 respectively), while no significant difference was found in SII groups (42.33% vs 46.31%, P = 0.067). Multivariable analyses identified PNI (P = 0.002) was an independent prognostic factor for OS, but NLR (P = 0.672) and PLR (P = 0.186) were not. Postoperative complications occurred significantly more frequently in the low-PNI group (29.69% vs 13.26%, P < 0.001). However, no significant differences were found in the postoperative complication rates between different NLR (16.67% vs 22.69%, P = 0.124), PLR (18.03% vs 19.61%, P = 0.867) and SII (15.34% vs 20.49%, P = 0.326) groups. Multivariate logistic regression analysis showed only PNI (P = 0.008) was an independent prognostic factor for postoperative complications.Preoperative low PNI was not only an independent prognostic factor for worse survival in esophageal cancer patients but also associated with high incidence of postoperative complications.

Introduction: Lung cancer is the leading cause of cancer death worldwide with poor survival rates. However, the prognostic factors for survival of patients with lung cancer are not well-established. In this study, we examined the impact of routine laboratory biomarkers and traditional factors on survival of patients with non-small cell lung cancer (NSCLC). Method: Secondary data analysis was conducted from a retrospective study of 404 patients with newly diag-nosed lung cancer in 2005-2007 in Taiwan. There were eight routine laboratory biomarkers and eight traditional factors investigated in the analyses. Cox proportional hazards model was used to assess the hazard ratios for the association between risk factors and patient overall survival. The Kaplan-Meier method was used to compare survival curves for each prognostic indicator. Results: High WBC counts (HR = 1.798, 95%CI: 1.225 - 2.639), low Hgb level (HR = 1.437, 95%CI: 1.085 - 1.903), and low serum albumin level (HR = 2.049, 95%CI: 1.376 - 3.052) were significant laboratory prognostic biomarkers for poor NSCLC survival. Additionally we confirmed the traditional prognostic factors for poor overall survival among NSCLC patients, including older age, comorbidity conditions, advanced cancer stage, and non-surgical treatment. Conclusions: This study identified three available laboratory biomarkers, high WBC counts, low Hgb level, and low serum albumin level, to be significant prognostic factors for poorer overall survival in NSCLC patients. Further prognostic evaluation studies are warranted to compare different ethnic groups on the prognostic values of these clinical parameters in NSCLC survival outcomes. These identified prognostic biomarkers should be included in early risk screening of hospitalized lung cancer patient population.
