First retrospective dosimetric comparison of three radiotherapy techniques for nasopharyngeal carcinoma in Mauritania: 3D-CRT, 3D-CRT+E, and VMAT

Eurasian Journal of Medicine and Oncology
Introduction: Radiotherapy remains the primary therapeutic option for nasopharyngeal carcinoma (NPC). The choice of technique, however, directly influences tumor control and the preservation of healthy tissues. Objective: This study aims to evaluate the dosimetry outcomes of three approaches: three-dimensional conformal radiation therapy (3D-CRT), 3D ...
