Transferring Your Radiation Treatment — to Another Centre Mid-Course

Yes. Moving radiotherapy part-way through a course is possible and is done regularly in India — most often for relocation, cost or the sheer distance of a daily journey. It is not a walk-in, though. The new centre needs your full plan files and delivered-dose record before it can safely continue where the old one stopped.

Nobody advertises this, so most families assume a course of radiation is all-or-nothing once the first session is done. It is not. Radiation oncologists move patients between centres often enough that there is a well-worn path for it. The obstacle is almost never permission — it is paperwork and timing.

One thing decides whether the move goes smoothly: whether the receiving centre gets your actual plan data, not a discharge summary. A summary describes what was intended. The plan files record what your body has already received. Only the second one lets a new team continue safely.

If CION is the centre you are moving to, your radiotherapy is delivered at an NABH-accredited partner centre; CION Cancer Clinics coordinates your treatment plan, your oncology team and your care throughout — including collecting and reviewing the records from your previous centre.

This page describes how transfers generally work in Indian practice. It is not legal advice, and every centre’s records process differs slightly — confirm the specifics with both centres.

Most mid-course transfers happen for practical reasons, not clinical ones. Daily travel from a district town becomes unsustainable. Money runs out or a scheme approval stalls. A family member relocates. Sometimes the patient simply stops feeling informed. None of these are unreasonable, and none should be hidden from your treating doctor.

The main risk is a gap in treatment. Radiation works best when sessions run to schedule, so days lost to paperwork genuinely matter. The other risks are re-planning delays, an incomplete dose record, machine differences at the new centre, and scheme approval having to be raised again from the start.

• An unplanned treatment gap. Guideline bodies such as ASTRO and NCCN stress completing a radiation course on schedule, because long unplanned breaks can reduce how well it works. Plan the move so the pause is as short as possible.
• An incomplete dose record. If the new centre cannot confirm exactly how much dose was delivered, and to which area, it cannot safely continue. This is the single most common cause of a stalled transfer.
• Re-simulation and re-planning time. A fresh CT simulation and new marks may be needed, especially if the technique differs. Budget several days for this, not a few hours.
• Machine and technique differences. Not every centre delivers treatment the same way. Your new radiation oncologist may adapt the remaining part of the plan — normal, but it takes review time.
• Scheme and insurance re-approval. Approvals are usually centre-specific, so a new pre-authorisation generally has to be raised before treatment can restart at the receiving centre.

None of this makes transferring a bad decision. It makes preparation the difference between a two-day pause and a three-week one.

The radiotherapy plan data itself, the planning CT it was built on, the record of dose already delivered and sessions completed, your setup details, your pathology and staging reports, imaging on media, and your scheme or insurance papers. A discharge summary on its own is not enough.

• The treatment plan, in digital form. Usually exported in DICOM-RT on a disc or drive. This is the item most often forgotten and the hardest to obtain later.
• The planning CT scan. The scan your plan was built on. Without it, the new centre cannot verify what was treated.
• The dose already delivered. The printed treatment record, signed, showing sessions completed. A figure written on a card by hand is not enough.
• Setup and immobilisation details. Position, any mask or cast, marking positions and daily imaging notes — so your setup can be reproduced.
• Pathology, staging and tumour board notes. The original biopsy and staging reports, plus any board discussion note (what a tumour board is).
• Imaging on media, not just reports. Ask for the actual CT, MRI or PET-CT images. Reports alone cannot be re-contoured.
• Consent form and treatment schedule. The consent form you signed and the schedule you were given.
• Scheme, insurance and billing papers. Approval letters, TPA correspondence and receipts for what has been paid so far.

Our step-by-step guide on how to get your radiation records and treatment plan files covers exactly how to word the request at the records desk.

Go back to the records desk anyway. Even if you stopped weeks ago, the new centre still needs the same files. Do not restart radiation anywhere without them — continuing without a verified record of what was delivered risks treating the same area either too little or too much.

Expect the new radiation oncologist to reassess rather than simply resume. Depending on how long the break has been and where you are in the course, they may want fresh imaging, a new simulation, or a full re-plan for the remaining sessions. That is a safety step, not a delay tactic.

Be straightforward about the gap. Under-reporting how long you have been away is far more damaging than the gap itself, because every decision about the remaining plan depends on that date. Bring the last session slip if you have it.

It is also worth checking that the centre you are moving to holds current AERB clearance for its radiation equipment. Our page on what AERB approval means for a radiation centre explains what to look for and how to ask.

Whatever the delay has been, the fix is the same: get the files, get them reviewed, and get a restart date in writing.
