Brief Summary:
The purpose of this study is to determine the maximal tolerated dose (MTD) of re-irradiation using carbon ion radiotherapy (CIRT) 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 maximal tolerated dose (MTD) in terms of acute and subactue 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.

Condition or disease Intervention/treatment Phase
Nasopharyngeal Carcinoma Radiation: Carbon ion radiotherapy (CIRT) Phase 1 Phase 2

Detailed Description:
The purpose of this study is to determine the maximal tolerated dose (MTD) of re-irradiation using carbon ion radiotherapy (CIRT) 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 55GyE (2.5GyE/daily fraction) to potentially 65GyE (2.5GyE/daily fraction) to evaluate the maximal tolerated dose (MTD) in terms of acute and subactue toxicity observed during and within 4 months after the completion of CIRT. Time-to-event continual reassessment method (TITE-CRM) is used for the phase I dose escalating part of the trial and approximately 25 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.

Arm Intervention/treatment
Experimental: CIRT Arm
Patients included in this arm were treated with carbon ion radiotherapy (CIRT).
Radiation: Carbon ion radiotherapy (CIRT)
Five dose levels (55GyE, 57.5GyE, 60GyE, 62.5GyE, 65GyE) are planned within the Phase I part. Daily fraction of 2.5 GyE will be delivered for all dose levels. After the recommended dose (RD), i.e., MTD, is determined or if the treatments to 65 GyE are safely delivered, the recommended dose (or 65 GyE) will be the prescribed dose in the Phase II part of the study. Ninty-five percent (95%) of the isodose line should cover the GTV+3~5mm.




Primary Outcome Measures :
  1. Number of participants with treatment-related adverse events as assessed by CTCAE v4.0 [ Time Frame: Time interval from the start of CIRT to 4 months after the completion of CIRT ]

Secondary Outcome Measures :
  1. Overall survival of all patients [ Time Frame: From the diagnosis of local recurrence of NPC, a median of 2 years ]
  2. Progression-free survival of all patients [ Time Frame: From the completion of CIRT, a median of 2 years ]
