Proton and heavy-ion therapy in Shanghai: ask whether it fits your case

Both are external-beam radiotherapy using charged particles. Protons and heavier ions have different physical and biological properties; neither is automatically the best choice for every tumour.

Shanghai has centres offering particle therapy, including the Shanghai Proton and Heavy Ion Center. Centre availability and the appropriate modality still need direct specialist confirmation.

A radiation oncologist may consider particle therapy when tumour location, nearby sensitive tissue, a prior radiation course or other clinical factors make dose distribution especially important. The team compares a realistic particle plan with high-quality conventional radiation and other treatment options.

A cancer diagnosis alone is insufficient. Some sites and stages have more supporting evidence than others, and heavy-ion evidence should not be presented as equivalent to proton evidence.

• Pathology diagnosis, stage and prior treatment history.
• Recent CT, MRI or PET images in original digital format, plus written reports.
• Previous radiation plans and dose records if any, not only a discharge summary.
• Current medicines, functional status and treating team’s proposed treatment goal.

Ask for a radiation-oncology review of the imaging and prior dose records. Clarify whether a planning scan, immobilisation device, further testing or a multidisciplinary review is needed. Treatment suitability may only be resolved after in-person planning.

Discuss the likely number of visits, travel fitness, accommodation near the centre and the plan for follow-up at home. Avoid non-refundable travel until the centre explains the next step.

A centre may review records, examine the patient, obtain a planning scan, design and verify a dose plan, then deliver a course of treatments with monitoring. The modality, number of fractions and schedule depend on the tumour and plan.

Ask who will manage symptoms during treatment and how records and follow-up will be transferred to the home oncology team.

Request separate figures for consultation, imaging or pathology review, planning, proton or heavy-ion treatment, supportive care and follow-up. Travel, accommodation, interpretation and MedRelay services are separate.

The course length and technique determine the estimate. A generic price cannot show total cost or whether another radiation method is more suitable.

Radiation can injure healthy tissue, and side effects vary with the treated area, dose, previous radiation and other therapies. Particle therapy still requires careful planning and quality checks.

Evidence that one technique improves a particular outcome is not equally strong across all cancers. A National Cancer Institute review notes limits of observational comparisons between proton and conventional treatment; ask the team what evidence applies to this tumour.

The multidisciplinary team may compare modern photon radiotherapy, surgery, systemic treatment, observation or supportive care depending on the diagnosis and goal. If proton and heavy-ion plans are both possible, ask why one is preferred.

We can organise imaging and prior radiation records, coordinate questions for a specialist centre and help plan travel and follow-up. The radiation oncologist decides suitability, technique and treatment.
