Trail Evaluating Carbon Ion Radiotherapy (3 GyE Per Fraction) for Locally Recurrent Nasopharyngeal Carcinoma

China51 participantsStarted 2016-01

Plain-language summary

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 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.

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 * Karnofsky Performance Score ≥70 * Willing to accept adequate contraception for women with childbearing potential * Ability to understand character and individual consequences of the clinical trial * Willing to sign the written informed consent; Informed consent must be signed before the enrollment in the trial Exclusion Criteria: * 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

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
