The prognosis of NX stage differentiated thyroid cancer based on propensity score matching and SEER data.

ABSTRACT: Few studies have evaluated the prognosis or treatment of patients with differentiated thyroid cancer (DTC) according to their NX status. This study investigated this issue to provide a new perspective regarding the treatment guidelines for these patients. Data from 92,447 patients with DTC were obtained from the Surveillance, Epidemiology, and End Results (SEER) database (2004-2013). Survival outcomes were evaluated using Kaplan-Meier analyses with the log-rank test and Cox proportional hazards regression analysis. The rates of cancer-specific mortality and all-cause mortality (per 1,000 person-years) were significantly higher for patients with NX disease, compared to patients with N0 or N1 disease. Multivariate Cox regression modeling revealed that NX stage was an independent risk factor
