Radiotherapy or chemoradiotherapy given with the intention of cure sometimes leaves disease behind, or the cancer returns in the same place. Surgery is then sometimes possible. It is called salvage surgery, it is genuinely difficult, and it is offered to a narrow group — but for some people it is the remaining route to cure. Dr Lawrence Okiror performs robotic navigational bronchoscopy to establish what the new area actually is, and carries out the surgery that follows.

Whether an operation is possible here is not a question about the disease. It is a question about this particular chest — how much radiotherapy it received, where, how long ago, and what the tissue has become since. Two people with the same cancer in the same place can get opposite answers.
That is why it cannot be settled from a clinic letter or a scan report, and why the answer given at the time of the original treatment does not necessarily hold now. Request a second opinion within 2–3 days →
Chemoradiotherapy given with the intention of cure works for many people. When it does not fully work, the disease very often reappears where it started rather than elsewhere — which is precisely the situation in which an operation might still achieve something, because there is one place to deal with.
Historically this was rarely attempted. Operating through an irradiated chest was regarded as too hazardous, and the assumption after failed radical treatment was that the disease must be beyond local control. Both positions have softened: surgical technique and perioperative care have improved, and modern imaging can establish with reasonable confidence whether disease really is confined to one place.
It remains an uncommon operation performed on carefully chosen patients. Nothing on this page should be read as suggesting it is straightforward or widely applicable.
This distinction is worth being clear about, because the two are easily confused and the difference in difficulty is substantial. Where chemotherapy and immunotherapy are given before a planned operation, the tissue is largely normal to work through and the timing is chosen for surgical convenience.

Salvage surgery has none of those advantages. The chest has received a radical dose of radiotherapy, the timing is dictated by when the problem was discovered, and the tumour may now involve structures it did not originally touch.
The assessment is genuinely a filter rather than a formality. Three things are being established: that this is one problem and not many, that all of it could realistically be removed, and that you could withstand the operation and recover from it. A weakness in any one of the three usually settles the matter.
Time since radiotherapy matters more than people expect. Cancer that reappears very soon after treatment tends to behave more aggressively; a longer interval before anything reappears is a favourable sign, and published series consistently find it among the features associated with better outcomes.
A lung operation normally proceeds by separating structures along planes that exist naturally between them. Radiotherapy removes those planes. Tissue that should come apart has to be divided, and the structures a surgeon is trying to protect are less clearly defined and more easily injured.
Healing is the second problem, and the more serious one. Irradiated tissue heals less reliably, and where an airway has been closed, a closure that fails is a major complication. Surgeons operating in these circumstances often reinforce the closure with healthy tissue brought in from outside the irradiated field.
The practical consequence is that these operations are more often done through an open incision than by keyhole. That is not a step backwards but a judgement: where the anatomy is unpredictable and control of a major blood vessel may be needed quickly, direct access is safer.
The imaging answers whether this is one problem. The fitness testing answers whether you could withstand the operation. The radiotherapy records answer a question specific to this situation: how much treatment the tissue has already absorbed, and therefore what the surgeon will be working through.
That last item is often overlooked when a patient moves between hospitals, and it is worth making sure it travels with you. More on fitness for lung surgery →
Robotic navigational bronchoscopy is the most accurate method currently available for sampling small and deeply placed areas within the lung. It is not yet widely available — the equipment is expensive and the training specific, and most UK units do not offer it. A three-dimensional map is built from your CT scan and a fine steerable instrument is guided along the airways to the target. You are asleep, there is no cut in the chest wall, and most people go home the same day.
In this setting it does something particularly valuable: it can establish that an area is not cancer, and spare someone a major operation they did not need. Dr Okiror performs it himself and performs any operation that follows, which means the person who took the sample is the person who discusses it in the multidisciplinary meeting and carries out the treatment.

That single comparison shapes the entire assessment. The question being asked is not whether an operation is technically possible, but whether it can realistically achieve complete removal. An operation that leaves cancer behind delivers all of the risk and, on those figures, very little of the benefit.
It also explains something patients sometimes find hard to hear: that the honest answer is often no. Declining to operate where complete removal looks unlikely is not caution for its own sake. It is the difference the numbers describe.
A meaningful proportion of people assessed for salvage surgery are advised against it. That advice is part of the value of the assessment rather than a failure of it.
Equally, some people are told locally that nothing surgical can be done, when the question has not been asked with full restaging and a tissue diagnosis. Those are different situations, and telling them apart is what a second opinion is for.
Those figures are not offered to discourage. They are offered because this is a decision that cannot be taken properly without them, and because a page that described this operation as routine would be misleading you about something that matters.
Individual risk is not the published average. It depends on what is being removed, how much radiotherapy was given and where, how well you breathe, and your general condition. Part of the consultation is converting these general figures into an estimate for you specifically, and saying it out loud rather than burying it in a consent form.
One risk deserves separate mention because it is specific to this operation. The nerve that drives the diaphragm runs close to the areas often involved, and in a scarred field it can be difficult to preserve. Where it is injured, the diaphragm on that side stops working and rises, which worsens breathlessness. That can be addressed by tightening the diaphragm during the same operation, and where the risk is anticipated it is discussed in advance. More on diaphragm surgery →
Radiotherapy to the lung reduces its function in the treated area, sometimes considerably, and a breathing test done before treatment does not describe the person sitting in the clinic now. The assessment has to be repeated.
It is worth saying that fitness moves in both directions. It declines with treatment. It also recovers — someone judged unfit for surgery during a difficult course of chemotherapy may be a different person a year or two later, particularly where the reason for that judgement was a side effect that has since resolved. A decision about operability taken at a hard moment does not automatically hold indefinitely, and it is reasonable to ask whether it has been revisited. More on borderline lung function →
There is a particular difficulty in this group that is worth naming. You have already been through a long and demanding course of treatment, probably with the expectation that it would be the end of it, and you are now being asked to do something harder. People arrive at this operation tired in a way that first-time surgical patients are not.
That is a real consideration and it belongs in the discussion rather than being treated as a matter of resolve. It affects how the recovery is supported, what help is arranged at home, and how the timing is set. More on recovery after lung surgery →
Nobody warns people about this, and it is one of the hardest parts of the whole experience. Having come through a difficult operation successfully, you enter a period of surveillance in which the scans are genuinely ambiguous. A follow-up scan describes increased soft tissue at the operated site. A PET scan is arranged and shows uptake that could be inflammation, infection, or cancer. A camera test is then done to settle it, and shows scarring from the radiotherapy. Months pass in that loop.
The honest thing to say is not that your scans will be clear. It is that your scans will be difficult to read for a long time, that the way of telling scar from cancer is usually to take a sample rather than to keep imaging, and that an uncertain scan in this setting is far more often nothing than something.
Repeated scans in a treated chest will frequently show something. Most of it is not cancer.
The pattern that matters is change over time, not any single image. Where a finding cannot be resolved by watching it, the answer is to sample it — which is often possible through the airways rather than by another operation.
Thymoma is the clearest example. It can come back locally, sometimes long after the original treatment, and it tends to return in the chest rather than elsewhere — which is exactly the pattern in which removing it can be worthwhile. Where the area has already received a radical dose of radiotherapy, further radiotherapy at that dose is generally not possible, and surgery becomes the remaining option.
These operations are assessed in the same way: is the disease confined, could all of it be removed, and could this person withstand the operation. More on thymoma surgery → and mediastinal surgery →
| Situation | Suggested action |
|---|---|
| Persistent or recurrent tumour in the irradiated field, PET and brain imaging clear | Surgical opinion before palliative intent is settled — complete resection is the variable that matters |
| Indeterminate PET uptake at a previously treated site | Tissue rather than serial imaging where the area is safely reachable |
| Further radiotherapy precluded by prior radical dose | Surgery may be the remaining radical option, including for chest wall and mediastinal disease |
| Patient judged unfit during chemoradiotherapy | Reassess — fitness recovers, and the earlier judgement may no longer hold |
| Recurrent thymoma or anterior mediastinal tumour in a treated field | Same assessment framework; not confined to lung cancer |
| Radiotherapy records unavailable | Obtain dose, volume and dates before assessment — they determine what the surgeon will encounter |
Referrals and self-referrals are seen at London Bridge Hospital and The Lister Chelsea, usually within 2–3 working days. Imaging, radiotherapy records and oncology correspondence can be reviewed in advance. Clinic letters go to GPs electronically within two working days, and within three working hours where urgent.
If radiotherapy or chemoradiotherapy has not fully worked and surgery has been ruled out without full restaging or a tissue diagnosis, an independent review is reasonable. Most patients are seen within 2–3 working days.
