Predictive value of preoperative serum CCL2, CCL18, and VEGF for the patients with gastric cancer

چکیده
BACKGROUND To investigate the expression of chemokine ligand 2 (CCL2), chemokine ligand 18 (CCL18), and vascular endothelial growth factor (VEGF) in peripheral blood of patients with gastric cancer and their correlation with presence of malignancy and disease progression. METHODS Sixty patients with pathological proved gastric cancer were prospectively included into study. The levels of CCL2, CCL18, and VEGF in peripheral blood were examined by enzyme-linked immunosorbentassay (ELISA). Peripheral blood from 20 healthy people was examined as control. RESULTS The preoperative serum levels of CCL2, CCL18 and VEGF in gastric cancer patients were significantly higher than that of controls (P <0.001, P <0.001, and P <0.001, respectively). ROC curve analysis showed that with a cut-off value of ≥1272.8, the VEGF*CCL2 predicted the presence of gastric cancer with 83% sensitivity and 80% specificity. Preoperative serum CCL2 was significantly correlated to N stage (P =0.040); CCL18 associated with N stage (P =0.002), and TNM stage (P =0.002); VEGF correlated to T stage (P =0.000), N stage (P =0.015), and TNM stage (P =0.000). CONCLUSION Preoperative serum levels of CCL2 and VEGF could play a crucial role in predicting the presence and progression of gastric cancer.

Evaluation of preoperative elevation of serum c-reactive protein as an indicator for prognosis of colorectal cancer
Abstract Background : Cancer has not been elucidated in colerectal site. C-reactive protein (CRP) is a product synthesized in hepatocytes and has been reported to be up-regulated by such proinflammatory cytokines as interleukin-1 (IL-1), interleukin-6 (IL-6), and tumor necrosis factor (TNF). The significance of a preoperative serum elevation was evaluated using CRP as a predictive i...

Background: Currently, non-invasive methods for screening atrophic gastritis and gastric cancer are lacking. The purpose of this study was to evaluate the value of serological parameters including serum pepsinogen I (PGI), pepsinogen II (PGII) and pepsinogen I: II ratio for the screening atrophic gastritis and gastric cancer. Methods : The study population consisted of 132 dyspeptic patient...
متن کاملHigh preoperative serum vascular endothelial growth factor levels predict poor clinical outcome after curative resection of gastric cancer.
BACKGROUND Tumour vascular endothelial growth factor (VEGF) and tumour urokinase-type plasminogen activator (uPA) are prognostic factors in gastric cancer but surgical specimens are required for testing. The prognostic value of preoperative serum VEGF (s-VEGF) and serum uPA (s-uPA) levels was evaluated in patients undergoing potentially curative (R0) gastric cancer resection. METHODS Concentr...
