Radiotherapy in China: Which Previous Radiation Records Should I Send?

Start with the radiotherapy summary, not the scan folder

When a patient asks which previous radiation records to send, the instinct is often to forward every imaging disc and blood result. That is not the most efficient first step. The document that changes a specialist's understanding fastest is the radiotherapy summary or completion note from the treating centre. It normally states the diagnosis, the target area, the total dose delivered, the number of fractions, the technique used, the start and end dates, and whether treatment was completed as planned.

That single document answers the question a reviewing clinician asks first: what has already been done to this part of the body? Without it, a new team may see follow-up scans showing radiation changes but have no context for when or how those changes were produced. With it, they can begin to judge whether a new course is even a relevant question, or whether the priority is assessing response, toxicity or a different treatment route.

If the summary is unavailable, ask the treating centre whether a completion letter, discharge summary or radiotherapy record can be released. A short factual letter from the radiation oncology department is more useful than a folder of unrelated scans.

• Radiotherapy summary or completion note: diagnosis, target, total dose, fraction number, technique, dates, completion status.
• If unavailable, request a brief factual letter from the radiation oncology department.

Planning and delivery records: what they add

The summary tells the story; the planning and delivery record tells the detail. This is where a specialist can see how the treatment was actually delivered, not just what was intended. Depending on the centre and the era of treatment, this may include the radiotherapy plan document, the dose distribution, the treatment fields or volumes, and the machine or technique used.

Dosimetry information is particularly valuable when a new course is being considered near a previously treated area. It helps the reviewing team understand what normal tissues received dose, which is central to judging whether further radiation is safe or feasible. Not every centre releases full dosimetry to patients, and older records may be incomplete. That is a limitation to state clearly rather than a reason to delay contact.

A practical point: send what exists, and label what is missing. A specialist can work with an incomplete but honest record far better than with a complete-looking file that turns out to be follow-up imaging only.

Imaging and pathology: context, not substitutes

Imaging is essential, but it plays a supporting role in this particular question. The scans used for the original radiotherapy plan show the target as it was then. Later scans show how things have changed. Both matter, but neither replaces the treatment record. A new specialist needs to compare the two, and that comparison only makes sense alongside the dose and technique information.

Pathology reports matter for a different reason. They confirm the diagnosis and, in some cases, the molecular or histological features that influence whether radiation is appropriate at all. If the original pathology was reported elsewhere, a review of the slides or blocks may be requested later. That is a separate step from sending records, and it should not be assumed in advance.

A useful organising principle: separate your documents into (1) diagnosis and pathology, (2) radiotherapy planning and delivery, (3) response and follow-up imaging, and (4) current clinical status. This structure lets a reviewing team find what they need without reading everything sequentially.

• Diagnosis and pathology reports, including any molecular or histological details.
• Original planning imaging and later follow-up scans, clearly dated.
• Current clinical status: symptoms, performance, recent assessments.

What a remote review can and cannot settle

A records-based review can clarify a great deal. It can establish what prior treatment was given, whether the records are internally consistent, and which questions remain open. It can help a specialist decide whether a consultation in China is worth arranging, and what further information would be needed first.

It cannot confirm suitability for a new course of radiotherapy. That decision depends on an in-person assessment, current imaging, the patient's overall condition, and the judgement of the treating radiation oncologist. It also cannot confirm that a particular technique or machine is available at a named hospital. Those are questions to ask the provider directly, not conclusions to draw from a website or a general article.

Remote review also cannot resolve gaps that only the original treating centre can fill. If the dose record is missing, no amount of new imaging replaces it. The honest position is to state what is known, what is missing, and what the receiving clinician would need to decide.

How to organise gaps without ordering new tests

Patients often ask whether they should arrange new scans before sending records. That is a clinical decision, not a logistical one. Ordering tests without a treating clinician's direction can produce information that is not what the receiving team needs, or duplicate imaging that was already done.

A better approach is to list the gaps and ask. For example: the radiotherapy summary is available but the dosimetry is not; the original planning CT is missing but follow-up imaging is complete; the pathology report is present but the slides are not. Present these as questions: would the receiving team need the dosimetry, and if so, can the original centre provide it? Would a pathology review be requested, and what material would be needed?

This keeps the patient in control of the information flow without making clinical decisions that belong to the treating team. It also avoids the common trap of sending a large, unstructured file that takes time to interpret and still leaves the key question unanswered.

• List what you have and what is missing, by category.
• Ask the receiving team which gaps matter for their assessment.
• Do not arrange new tests without a clinician's direction.

What the specialist must decide, and how to prepare for that conversation

The specialist's decision is not simply whether more radiation is possible. It is whether the prior treatment, the current disease status, the normal tissue tolerance, and the patient's goals make further radiotherapy a reasonable option at all. That decision requires the records described above, a current assessment, and a discussion of alternatives.

Before that conversation, prepare three things. First, a one-page timeline: diagnosis date, treatment dates, and key follow-up milestones. Second, a clear statement of the current question: is this about a new course near a previously treated area, a different site, or a decision between radiation and another approach? Third, a list of the specific records you have and those you cannot obtain.

This preparation does not replace the clinical assessment, but it makes the assessment more productive. It also helps the patient understand which parts of the decision are already settled by the records and which remain open until the specialist reviews everything in person.

One further distinction is worth making before the appointment. A consultation, a radiotherapy plan and the delivery of treatment are three separate stages, and records that answer questions about one stage may not answer questions about another. A completion note tells you what was delivered. A planning document tells you how it was designed. Neither tells you what a new team would propose, because that depends on an assessment that has not yet happened. Keeping these stages separate prevents a common misunderstanding: that sending a complete file is the same as receiving a treatment decision.

It also helps to decide in advance what you would do with each possible answer. If the reviewing clinician says the records are sufficient for a consultation, the next step is scheduling and preparation. If they say a specific document is missing, the next step is requesting it from the original centre. If they say the question cannot be answered remotely, the next step is an in-person assessment or a different treatment route. Knowing these branches beforehand makes the reply easier to act on, rather than leaving you to interpret a short message without context.

Finally, keep a written record of what you sent, when, and to whom. If a document is later requested again, you can point to the earlier submission instead of starting over. This is administrative, not clinical, but it reduces the chance that a missing attachment is mistaken for a missing treatment record. A short cover note listing the enclosed documents by category, with dates, does more for a reviewing team than a large unlabelled file.

The records described in this guide are the ones that change a specialist's understanding of prior radiotherapy. They do not guarantee that further treatment is appropriate, available or advisable, and they do not replace an in-person assessment. What they do is give the receiving clinician a factual basis for the next conversation, and give you a clearer sense of which questions are already answered and which still need to be asked. If you would like help identifying which documents to gather first, an initial enquiry is free and does not commit you to any paid service.
