Prognostic value of intra-tumoral CD8+ /FoxP3+ lymphocyte ratio in patients with resected colorectal cancer liver metastasis.

ABSTRACT: BACKGROUND AND OBJECTIVES:Patients with isolated colorectal-cancer-liver-metastases (CRCLM) frequently undergo metastatectomy. Tumor-infiltrating-lymphocytes (TILs) have prognostic potential in the setting of primary colorectal cancer, however, their role in CRCLM is less studied. We aimed to study the spatial distribution and prognostic role of tumor-infiltrating CD8+ cytotoxic T-cells and FoxP3+ regulatory T-cells at the metastatic site of CRCLM patients. METHODS:TILs were isolated from fresh metastatic tissues of 47 patients with CRCLM. Archived paraffin-embedded tissue, from the same patients, was retrieved. CD8+ and FoxP3+ cells, both in the intra-tumoral and the peri-tumoral compartments, were measured by immunohistochemistry on full tissue sections. Proportions of cytotoxic T-cells (CD8+ ) and regulatory T-cells (CD4+ CD25+ FoxP3+ ), within CD45+ TILs, were measured by flow-cytometry. RESULTS:By immunohistochemistry, individual densities of intra-tumoral or peri-tumoral CD8+ and FoxP3+ cells were not prognostic of survival. However, the intra-tumoral, but not the peri-tumoral, CD8+ /FoxP3+ ratio was an independent predictor of survival (HR 0.43, 95%CI 0.19-0.95, P?=?0.032). By flow cytometry, the intra-tumoral CD8+ /regulatory T-cell ratio was also an independent predictor of survival (HR 0.45, 95%CI 0.20-0.99, P?=?0.044). CONCLUSIONS:The ratio of cytotoxic (CD8+ ) to regulatory (FoxP3+ ) T-cells, in the intra-tumoral compartment, but not in the peri-tumoral compartment, can predict survival after resection of CRCLM.

Project description:BackgroundHemodialysis (HD) is the most important renal replacement therapy for patients with end-stage kidney disease (ESKD). Systemic inflammation is a risk factor of mortality in HD patients. Neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and platelet-to-lymphocyte ratio (PLR) are new inflammatory markers. However, previous studies have inconsistent conclusions about the predictive value of NLR, MLR and PLR on mortality of HD patients. The aim of this study was to establish an inflammation scoring system by including NLR, MLR and PLR, and evaluate the association between the inflammation score and all-cause and cardiovascular mortality in HD patients.MethodsIn this single center retrospective cohort study, 213 incident HD patients from January 1, 2015 to December 31, 2020 were included. Baseline demographic and clinical data and laboratory measurements were collected. According to the optimal cut-off values, NLR, MLR and PLR were assigned 0 or 1 point, respectively. Then, the inflammation score was obtained by adding the NLR, MLR and PLR scores. All patients were followed until July 31, 2021. The associations of the inflammation score with all-cause and cardiovascular mortality were assessed by multivariable-adjusted Cox models.ResultsOf 213 patients, the mean (± SD) age was 56.8 ± 14.4 years, 66.2% were men, and 32.9% with diabetes. The primary cause of ESKD was mainly chronic glomerulonephritis (46.5%) and diabetic nephropathy (28.6%). The median inflammation score was 2 (interquartile range = 1-3). During a median 30 months (interquartile range = 17-50 months) follow-up period, 53 patients had died, of which 33 deaths were caused by cardiovascular disease. After adjusting for demographics, primary diseases and other confounders in multivariable model, the inflammation score = 3 was associated with a hazard ratio for all-cause mortality of 4.562 (95% confidence interval, 1.342-15.504, P = 0.015) and a hazard ratio for cardiovascular mortality of 4.027 (95% confidence interval, 0.882-18.384, P = 0.072).ConclusionIn conclusion, an inflammation scoring system was established by including NLR, MLR and PLR, and the higher inflammation score was independently associated with all-cause mortality in HD patients.
