Intra-Tumoral ClO2 Therapy Portfolio – Case Report: Complete Remission of Advanced Nasopharyngeal Cancer in Rural China

Abstract

This report documents the complete remission of a recurrent nasopharyngeal carcinoma following 10 injections of intratumoral chlorine dioxide (ClO₂). The treatment was performed without image guidance, anesthesia, or hospital support, by a rural physician in Xinjiang, China. CT and endoscopy confirmed total tumor collapse with significant clinical recovery. This case demonstrates the feasibility and efficacy of intratumoral ClO₂ therapy in low-resource environments.
