Individualized Carbon-Ion Radiotherapy for Patients With Locally Recurrent Nasopharyngeal Carcinoma

October 16, 2020 updated by: Jiade J. Lu, Shanghai Proton and Heavy Ion Center

Predictive-Model Based Individualized Carbon-Ion Radiotherapy for Patients With Locally Recurrent Nasopharyngeal Carcinoma: A Phase 2 Randomized Trial

This is a randomized phase 2 trial with 2 groups (control group vs experimental group). Patients with locally recurrent nasopharyngeal carcinoma (LR-NPC) assigned to the control group will receive standardized carbon-ion radiotherapy (CIRT). For patients assigned to the experimental group, a predictive model will be used to predict the chance of developing mucosal necrosis after salvage carbon-ion radiotherapy, and individualized dose prescription will be given. The primary endpoint of the study is to compare the 2-year progression-free survival (PFS) between 2 groups.

Detailed Description

This is a randomized phase 2 trial with 2 groups (control group vs experimental group). Patients with locally recurrent nasopharyngeal carcinoma (LR-NPC) assigned to the control group will receive standardized CIRT with a dose of 63 gray equivalent (GyE) in 21 fractions (fx). This regimen was obtained from our previous phase 1 (dose escalation) study. For patients assigned to the experimental group, a predictive model will be used to predict the chance of developing mucosal necrosis after salvage carbon-ion radiotherapy, and individualized dose prescription will be given. A dose of 60 GyE/20 fx, 63 GyE/21 fx and 66 GyE/22 fx will be given to patients with high, moderate and low risk of developing mucosal necrosis, respectively. The primary endpoint of the study is to compare the 2-year progression-free survival (PFS) between 2 groups. The secondary endpoints include 2-year overall survival (OS), local progression-free survival, regional progression-free survival, distant metastasis-free survival, toxicities and quality of life.
