The prognostic value of adding systemic inflammation response index to Epstein-Barr virus DNA in childhood nasopharyngeal carcinoma: A real-world study.

Background: To assess the prognostic value of the systemic inflammation response index (SIRI) combined with plasma load of Epstein-Barr virus (EBV) DNA in children and adolescents with locoregionally advanced nasopharyngeal carcinoma (CALANPC).

Methods: A total of 205 consecutive patients with CALANPC were enrolled. We used recursive partitioning analysis (RPA) to classify patients into various risk groups, with a primary endpoint of overall survival (OS).
