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.

Conditions

  • Nasopharyngeal Carcinoma

Interventions

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.
