Carbon-ion radiotherapy: recurrent nasopharyngeal cancer: consultation records checklist 1. Retrieve previous radiotherapy DICOM plans, dose and structure files for cumulative dose assessment 2. Provide the latest nasopharyngeal MRI and systemic staging images to define recurrence extent 3. Organise recurrence pathology and original diagnostic reports to distinguish recurrence from radiation injury 4. List bleeding, necrosis, hearing changes and medicines to assess re-irradiation risk Questions to clarify - Do I meet the eligibility criteria? - What are the separate medical and coordination service costs without Chinese health insurance or free-drug assistance? - How are initial treatment, ongoing treatment, return travel and follow-up arranged? - Which risks require immediate contact with the hospital? An initial service consultation does not replace medical assessment.
