Abstract
Neutrophil–lymphocyte ratio (NLR) was shown to be prognostic value in various malignancies. There are limited data about predictive or prognostic role of NLR during gastrointestinal stromal tumors (GISTs) patients. This study evaluated the prognostic significance of preoperative NLR in patients with GIST.We retrospectively enrolled 72 primary GIST patients who received initial curative surgical resection with or without adjuvant imatinib therapy. The preoperative NLR in the peripheral blood was calculated. Univariate and multivariate Cox proportional hazard regression models were used to identify potential predictors of tumor outcomes.The NLR cut-off value of 4.18 was selected. Multivariate analysis revealed that high NLR was associated with a unfavorable prognosis of GISTs (P < .05). Tumor size, tumor location, and age were significantly correlated with the NLR (P < .05).High NLR was an unfavorable prognostic factor of overall survival in GISTs and may be a useful preoperative biomarker of the prognosis of GISTs.
