Trail Evaluating Carbon Ion Radiotherapy (3 GyE Per Fraction) for Locally Recurrent Nasopharyngeal Carcinoma
February 12, 2020 updated by: Jiade J. Lu, Shanghai Proton and Heavy Ion Center
Phase I/II Trail Evaluating Carbon Ion Radiotherapy (3 GyE Per Fraction) for Salvaging Treatment of Locally Recurrent Nasopharyngeal Carcinoma
The purpose of this study is to determine the maximal tolerated dose (MTD) of re-irradiation using carbon ion radiotherapy (CIRT) with the fraction size of 3 gray equivalent (GyE) in the treatment of locally recurrent nasopharyngeal cancer (NPC) and to evaluate the efficacy of such treatment at the MTD.
Participants will be treated with CIRT with escalating dose regimens to evaluate the MTD in terms of acute and subacute toxicity observed during and within 4 months after the completion of CIRT.
Once the MTD for locally recurrent NPC is determined, the MTD will be used as the recommended dose to patients fulfilling the inclusion criteria in the Phase II part of the trial.

Detailed Description
The purpose of this study is to determine the maximal tolerated dose (MTD) of re-irradiation using carbon ion radiotherapy (CIRT) with the fraction size of 3 GyE in the treatment of locally recurrent nasopharyngeal cancer (NPC) and to evaluate the efficacy of such treatment at the MTD.
Participants will be treated with CIRT with escalating dose starting from 54GyE (3GyE/daily fraction) to potentially 63GyE (3GyE/daily fraction) to evaluate the maximal tolerated dose (MTD) in terms of acute and subacute toxicity observed during and within 4 months after the completion of CIRT.
The classic 3+3 method is used for the phase I dose escalating part of the trial and approximately 4-18 patients will be accrued.
Once the MTD for locally recurrent NPC is determined, the MTD will be used as the recommended dose to patients fulfilling the inclusion criteria in the Phase II part of the trial.
The Phase II part of the trial will be a single phase single arm study.

Description
Inclusion Criteria:
- Completed a definitive course of intensity-modulated photon radiation therapy (IMXT) to a total dose of ≥ 66 Gy
- Recurrence diagnosed more than 12 months after the initial course of IMXT
- Age ≥ 18 and < 70 years of age

- Presence of distant metastasis
- Technology used other than IMXT (including brachytherapy following IMXT) for the treatment of initial diagnosis of NPC
- Pregnant or lactating women
- Patients who have not yet recovered from acute toxicities of prior therapies
- A diagnosis of malignancy other than carcinoma in situ of the cervix, basal cell carcinoma and squamous cell carcinoma of the skin within the past 5 years
- Refusal of the patient to participate into the study

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: CIRT Arm (3GyE per fraction)
Patients included in this arm were treated with carbon ion radiotherapy with a fraction size of 3GyE.
|
Four dose levels (54GyE, 57GyE, 60GyE, 63GyE) are planned within the Phase I part.
Daily fraction of 3 GyE will be delivered for all dose levels.
After the recommended dose (RD), i.e., maximal tolerated dose, is determined or if the treatments to 63 GyE are safely delivered, the recommended dose (or 63 GyE) will be the prescribed dose in the Phase II part of the study.
Ninety-five percent (95%) of the isodose line should cover the gross tumor volume plus 3~5mm.
