Reduced Dose Radiotherapy vs Standard Dose Radiotherapy for Early Stage Nasopharyngeal Carcinoma

Recruiting now · Phase 3

Conditions studied: Nasopharyngeal Cancinoma (NPC)

In brief

This study investigates whether administering reduced dose is non-inferior to standard dose radiotherapy in terms of 3-year locoregional relapse-free survival (LRRFS) rate for stage I nasopharyngeal carcinoma patients who are sensitive to radiotherapy.
