Dose volume effects of re‐irradiation for locally recurrent nasopharyngeal carcinoma

Background This study analyzed the dose volume effects of re‐irradiation for locally recurrent nasopharyngeal carcinoma (NPC) and attempts to determine the optimal dose for the best survival. Methods Ninety‐one patients were studied. The local control, fatal complication, and overall survival were analyzed against the dose (in Equivalent Dose at 2 Gy/fractions) and recurrent gross tumor volume (GTV). Results The local control and fatal...
