Abstract

The neutrophil‑to lymphocyte ratio (NLR) has been proven to be correlated with outcomes in various cancer types, including gastrointestinal stromal tumors (GIST). There is limited data regarding the clinical value of NLR during second line therapy after failure of imatinib and there is an urgent need for more precise predictive factors for therapy. The aim of this study was to assess the association of the pretreatment NLR with progression free survival (PFS) and overall survival (OS) in patients with unresectable/metastatic GIST treated with sunitinib in a second line of treatment. In this analysis 146 out of 230 patients with unresectable/metastatic GIST were included, who were treated between 2005 and 2016 with sunitinib after failure of imatinib, with complete clinical data. In all patients, the NLR was assessed at baseline. The NLR cutoff of 2.4 was selected. The Kaplan‑Meier method with the long‑rank test and Cox proportional hazards model were applied for statistical analysis. Median PFS was 12.4 months with a 2‑year rate of 27.1% and a 5‑year rate of 4.8%. Median OS was 22.8 months, whereas 2‑ and 5‑year rates were 47.8 and 13.8%, respectively. Patients with NLR>2.4 had significantly shorter OS: Median OS was 30 months for NLR≤2.4 vs. 16.4 months for NLR>2.4 (P=0.002); median PFS was 18.2 vs. 9.6 (P=0.075), respectively. In a multivariate model adjusted for mitotic index, primary location of tumor and driver mutation in KIT exon 11, NLR was proven to be independently associated with OS (HR 1.92, 95% CI 1.27‑2.9, P=0.002) but not PFS (HR 1.31, 95%CI 0.89‑1.93, P=0.17). The present data demonstrate that NLR can serve as an independent prognostic factor for patients with advanced GIST treated with sunitinib.
