Splenic hamartoma has some specific radiological features. However, the diagnosis of this disease must be based on clinical features and confirmed by pathology.

An increased neutrophil-to-lymphocyte ratio (NLR) is associated with poorer prognostic outcomes in numerous types of cancer. However, a small number of studies have demonstrated the prognostic role of NLR in patients with laryngeal cancer. The present study evaluated the association between NLR and survival outcomes in patients with laryngeal squamous cancer. All patients were scheduled for follow-up visits. The levels of cytokines from tumor tissues were analyzed by ELISA. A classification and regression tree (CART) was used to determine the optimal cutoff values of NLR. The clinical features and NLR were determined using Kaplan-Meier analysis and Cox regression to analyze the survival outcomes and associated risks. Of the total 654 patients, 70 patients (70/654; 10.7%) failed to receive follow-up. Blood and biochemical parameters, including NLR, platelet-to-lymphocyte ratio and albumin-to-globulin ratio were associated with clinical characteristics of the patients, with the exception of histologic grade. Only one node with NLR at 3.18 divided patients into different categories, according to CART analysis. Survival analysis demonstrated that NLR at cutoff values subdivided patients into different survival outcomes (P<0.001). Subsequent to adjustments for age and other clinical features, NLR was identified to be an independent prognostic factor for overall survival and progression-free survival (P<0.05). Increased levels of cytokines, including IL-6 and IL-8, in tumor tissues were associated with NLR values. In summary, pre-treatment NLR was associated with the prognostic outcomes for patients with laryngeal cancer, and may assist to establish prognostic factors for these patients.
