Who should not have HIPEC, and why teams say no | CION Cancer Clinics
HIPEC is usually not offered when the cancer has spread beyond the abdomen, when there is too much cancer on the lining for a surgeon to clear, or when the person is not well enough for an operation that lasts most of a day. Some of those reasons are fixed. Others can change with chemotherapy, nutrition or time. This page explains each reason, and what to ask if you have been told no. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
Who is usually not offered HIPEC?
HIPEC is usually not offered when the cancer has spread beyond the abdomen, when there is too much cancer on the lining for a surgeon to clear, or when the person is not well enough to come through an operation that lasts most of a day. It is also not offered for cancer types where the evidence shows little benefit.
Why the team says no
This operation only helps if nearly all the visible cancer can be removed and the rest of the body is free of it. If either of those is not true, the person goes through a very hard operation and recovery for little gain. A no from the team is a judgement that the harm would outweigh the help, not a judgement about you.
A firm no and a not-now are different
Some reasons are fixed: the cancer type, or spread to the lungs or bones. Others can change. Poor nutrition can be improved. A chest infection can be treated. Chemotherapy can shrink disease so that a later scan looks different. It is worth asking which kind of no you have been given.
This page describes what teams weigh. It cannot tell you whether you, or your parent, should or should not have the operation. That belongs to the treating team, with you in the room.The reasons
What rules HIPEC out?
Spread outside the abdomen
Cancer in the lungs, the bones, the brain or in lymph nodes far from the abdomen means the lining is not the only problem. Treating the lining alone would leave the rest untreated, so the operation is not offered. Some teams make an exception for a small amount of liver disease with colorectal spread.
Too much disease to clear
The surgeon scores the amount of cancer on the lining region by region. Above a certain amount, which differs by cancer type, the chance of removing nearly all of it falls sharply. The operation is then not offered, because leaving disease behind removes most of the benefit.
Cancer wrapped around the small bowel
The small bowel cannot be stripped like other surfaces and only so much of it can be removed. Disease spread widely along it, or a blocked bowel that cannot be freed, is one of the commonest reasons an operation is stopped early or not started.
Not fit enough for the operation
Severe heart, lung or kidney disease, serious weight loss, or being unable to get about on your own all raise the risk of the operation beyond what the team can justify. Age on its own is not a reason. Fitness is.
Also weighed
- Cancer types with little evidence of benefit
- An active infection that has not settled
Not sure whether this applies to you?
Ask an oncologistSide by side
Which reasons are fixed, and which can change?
Usually fixed
Can sometimes change
Spread to the lungs, bones or brain
Disease that shrinks after chemotherapy
A cancer type the evidence does not support
Poor nutrition, improved with a dietitian and time
Widespread disease along the small bowel
A chest or wound infection that is treated
Severe heart, lung or kidney disease
Low fitness that improves with a walking programme
Commonly believed
Four things families tell us after being told no
"If they will not operate, there is nothing left to do."
Not being suitable for one operation does not mean no treatment. Chemotherapy through a vein, chemotherapy given into the abdomen as a fine mist called PIPAC, and treatment aimed at comfort and symptoms are all real options. Ask what the plan is now, not only what it is not.
"Another hospital will do it if we pay."
A second opinion from a team that does this operation regularly is sensible. A centre that says yes without looking at your scans, or without explaining what it expects to achieve, is not offering a second opinion. It is offering an operation.
"He is too old, that is why they refused."
Age by itself is rarely the reason. Teams look at how the heart, lungs and kidneys are working and how active the person is. If you were told no, ask which fitness test was the concern and whether anything can be done about it.
"They gave up because the scan showed stage 4."
Spread to the lining is usually recorded as stage 4, and that alone does not rule the operation out. What rules it out is spread beyond the abdomen, or too much disease to clear. Those are different things, and the report will say which applies.
Leave a number, we will call you
One field. No form to fill in, and no charge for the call.
On your report
Words you may see in the reason given
- Extra-peritoneal disease
- Cancer outside the abdominal cavity, such as in the lungs or bones. Its presence usually rules HIPEC out.
- PCI
- The Peritoneal Cancer Index, a score for how much cancer sits on the lining. A very high score is a common reason for a no.
- Small bowel involvement
- Cancer spread along the outside of the small bowel. The small bowel cannot be stripped, so this limits what a surgeon can remove.
- Performance status
- A simple score for how active you are day to day. A low score means the body is unlikely to cope with a very long operation.
- Open and close
- An operation that is started but stopped early because the surgeon finds more disease than the scans showed.
- Systemic chemotherapy
- Chemotherapy given through a vein so that it reaches the whole body, rather than being put into the abdomen.
Did you know
Scans regularly under-count small deposits on the lining, which is why some people are told yes on the scan and no in the operating theatre. A short keyhole look beforehand exists to reduce exactly that.
Being straight with you
What should you ask after being told no?
Ask which reason applied to you, in plain words. Ask whether it is fixed or whether it could change, and if so, when it would be looked at again. Ask what treatment is being recommended instead and what its aim is: to shrink the cancer, to hold it steady, or to keep you comfortable.
If you want a second opinion
Cancer on the lining of the abdomen is uncommon, and this operation is done in only a few centres. Asking another team to look at the same scans is reasonable and your first doctor will not be offended. Take every scan, report and letter with you, and ask the second team the same questions.
What this page cannot tell you
It cannot tell you what your own team saw on your scans, and it cannot say whether their decision was right. A list of reasons is not a judgement about any one person. If you are unsure what you were told, or why, ask for it in writing and bring it to someone who can explain it.
If you would like help understanding a decision you have been given, call the helpline. An oncologist will go through the reports with you.Questions we are asked
Common questions about being turned down for HIPEC
My mother was told her PCI is too high. Is that final?
Usually, but not always. For slow-growing disease like pseudomyxoma, a high score can still be operable. For colorectal or stomach spread, a high score is a firm reason. Ask which cancer type she has, whether chemotherapy first might lower the amount of disease, and whether the team would re-scan afterwards.
The surgeon opened the abdomen and closed it again. Why?
Because the surgeon found more disease than the scans showed, most often along the small bowel, and judged that it could not be cleared. Going ahead would have meant a very hard recovery for no real benefit. It is a difficult day for a family, and it is a decision made to protect the patient.
Can he have HIPEC if the cancer is also in the liver?
Usually not. Some teams will consider it when there is only a small amount of liver disease alongside colorectal spread, and when both can be dealt with. Widespread liver disease rules it out. Ask your team directly whether your case falls into the narrow group where it is still considered.
Is diabetes or high blood pressure a reason for no?
Not on their own. Well-controlled diabetes and blood pressure are common in people who have this operation. What matters is whether the heart, lungs and kidneys have been damaged, and that is what the fitness tests look at. Poorly controlled diabetes may be a reason to delay while it is brought under control.
What happens instead of surgery?
Most often chemotherapy through a vein, which treats the whole body. In some centres, chemotherapy given into the abdomen as a fine mist, called PIPAC, is used for disease that cannot be operated on. Treatment aimed at symptoms, such as draining fluid or relieving a blocked bowel, is part of the plan too.
Can a no become a yes later?
Sometimes. If the reason was nutrition, an infection, or the amount of disease, chemotherapy and time can change the picture. If the reason was spread beyond the abdomen or the cancer type, it rarely changes. Ask your team to say plainly which kind of reason applies to you.
Does stopping at a keyhole look mean the cancer is worse?
It means the surgeon saw something the scan did not, most often the extent of disease on the small bowel. That may not change the stage at all. It changes what surgery can offer. Ask what was seen, and what the team recommends now.
Will Aarogyasri or insurance cover the other treatments?
Chemotherapy and symptom treatment are usually covered when they are part of an approved cancer plan. Aarogyasri, CGHS, ECHS and EHS are accepted, and most cashless insurers are empanelled. Call the helpline with your card details and we will check your cover before you travel.
