Abstract
Extranodal natural killer/ T-cell lymphoma (ENKTL) is a rare malignant tumor. This study aimed to develop a predictive nomogram and a web-based survival rate calculator for dynamically predicting the survival of patients with sinonasal ENKTL (SN-ENKTL). This study investigated patients (n=134) with SN-ENKTL who had been initially treated in our hospital between Jan 2008 and Dec 2016. The patients were randomly divided into training and validation cohorts, in a 7:3 ratio. Independent prognostic factors were identified and integrated to build a predictive nomogram and a web-based calculator using the Cox-regression model. The nomogram was evaluated by consistency index and calibration curve. Age, lactate dehydrogenase, hemoglobin, Epstein-Barr virus DNA, and Ann Arbor stage were identified as independent risk factors. We constructed a predictive nomogram for survival and a web-based calculator (https://taiqinwang.shinyapps.io/DynNomapp/). This study developed a prognostic model and a web-based calculator specifically focused on SN-ENKTL for otolaryngologists to use to facilitate timely treatment decisions for the disease. 4 Laryngoscope, 133:1645-1651, 2023.
