Cisplatin

Treated with carcon ion radiotherapy along with concurrent chemotherapy (Cisplatin 40mg/m\^2, weekly).

Five dose levels (52.5GyE, 55GyE, 57.5GyE, 60GyE, 62.5GyE) 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 62.5 GyE are safely delivered, the recommended dose (or 62.5 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 GTV+3\~5mm.

Carbon ion radiotherapy (CIRT)

Cisplatin (40mg/m\^2) monotherapy will be given weekly along with radiotherapy.

Jiade J Lu, MD

The purpose of this study is to determine the maximal tolerated dose (MTD) of re-irradiation using carbon ion radiotherapy (CIRT) along with concurrent chemotherapy 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 along with concurrent chemotherapy (40 mg/m\^2, weekly) to evaluate the maximal tolerated dose (MTD) in terms of acute and subacute toxicity observed during and within 4 months after the completion of concurrent chemoradiotherapy. 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 purpose of this study is to determine the maximal tolerated dose (MTD) of re-irradiation using carbon ion radiotherapy (CIRT) along with concurrent chemotherapy in the treatment of locally recurrent nasopharyngeal cancer (NPC) and to evaluate the efficacy of such treatment at the MTD in the setting of concurrent chemoradiotherapy. Participants will be treated with CIRT with escalating dose starting from 52.5GyE (2.5GyE/daily fraction) to potentially 62.5GyE (2.5GyE/daily fraction) along with concurrent chemotherapy (40 mg/m\^2, weekly) to evaluate the maximal tolerated dose (MTD) in terms of acute and subacute toxicity observed during and within 4 months after the completion of concurrent chemoradiotherapy. 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 in the setting of concurrent chemoradiotherapy 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.

Phase I/II Trial Evaluating Carbon Ion Radiotherapy With Concurrent Chemotherapy for Salvaging Treatment of Locally Recurrent Nasopharyngeal Carcinoma

Shanghai Proton and Heavy Ion Center

Patients included in this arm were treated with 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.

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.
