Accuracy of a Staging System for Prognosis of 5-Year Survival of Patients With Nasopharyngeal Carcinoma Who Underwent Chemoradiotherapy.

ABSTRACT:

Importance

Concurrent chemoradiotherapy delivers a high level of tumor control and survival benefits for patients with nasopharyngeal carcinoma (NPC). However, many uncertainties still exist regarding the outcomes of chemoradiotherapy, making a more precise survival prognostic system necessary.

Objective

To introduce a new staging system that combines tumor and clinical characteristics to improve the accuracy of prognosis for patients with NPC.

Design, setting, and participants

This cohort study enrolled 207 patients with newly diagnosed NPC who underwent concurrent chemoradiotherapy between January 1, 2007, and December 31, 2014, at Chi-Mei Medical Center in Tainan, Taiwan. Data on these patients were collected from the cancer registry database of the Chi-Mei Medical
