Population-based nasopharyngeal carcinoma survival in southern China.

ABSTRACT:

Background

Few population-based studies on nasopharyngeal carcinoma (NPC) prognosis exist. Such real-world data with complete follow-up are needed to enable accurate estimation of survival probabilities and monitor progress in early detection and treatment.

Methods

In a population-based study of 2529 patients with incident NPC in southern China diagnosed in 2010-2013, we developed a passive-active-passive follow-up strategy involving data linkage and direct contact to track patients' vital status, cause of death, and migration through December 31, 2018. We calculated 5-year survival probabilities by the Kaplan-Meier method, and estimated avoidable deaths comparing hypothetical scenarios and real-world observations.

Results

Early-stage (I-II) patients accounted for 11·
