In short
After stomach cancer treatment, regular visits look for the cancer coming back and for problems with eating, weight, vitamins and blood count.
The visits are closest in the first two or three years, when most returns happen. They are spaced out later, but not stopped too early.
A CT scan, an endoscopy, blood markers and a talk about eating and weight are the main tools. No single test is enough on its own.
How stomach cancer is tested, staged and treated is set out on the stomach cancer treatment in Ahmedabad page. This post covers what happens after the treatment is over.
Follow-up has two jobs. It finds a return of the cancer while something can still be done, and it keeps the body well fed after the operation.
Some years ago, finding a return early changed little. That has moved on. Better chemotherapy and newer medicines now help many people whose cancer comes back. In a small group, a single spot that returns can even be removed again.
The second job matters just as much. After part or all of the stomach is removed, people eat less, lose weight, and can run short of vitamin B12, iron, calcium and vitamin D. These are easy to check and easy to treat when found.
How often you are seen depends on the risk of return. That risk comes from the final report on the removed stomach and its glands.
The cancer is called higher risk when it had grown deep into or through the stomach wall, reached the glands, or was of the signet ring type. It is called lower risk when it was early and the glands were clear.
| Time after treatment | Higher risk | Lower risk |
|---|---|---|
| First year | Visit every 3 months; CT scan about every 3 to 6 months; endoscopy at one year | Visit every 3 to 6 months; CT scan every 6 months; endoscopy at one year |
| Second year | Visit every 4 to 6 months; CT scan every 6 months; endoscopy yearly | Visit every 3 to 6 months; CT scan every 6 months; endoscopy yearly |
| Third year | Visit and CT scan every 6 months; endoscopy yearly | Visit and CT scan once a year; endoscopy yearly |
| Fourth and fifth years | Visit and CT scan once a year; endoscopy every 1 to 2 years | Visit and CT scan once a year; endoscopy yearly |
| After five years | Yearly visit; scan and endoscopy less often, as advised | Visit with scan and endoscopy every 2 to 3 years |
This is a guide, not a fixed rule. The plan is set for each person, and it changes if a new problem appears.
Each visit starts with a talk and an examination. The questions are simple, but they find most problems.
Blood tests are done at most visits: blood count, vitamin B12, iron, liver and kidney tests, and the cancer markers that were raised before treatment.
Weight is recorded each time. A steady fall in weight is one of the earliest signs that something needs attention, whether eating or the cancer.
A CT scan of the chest, belly and pelvis is the main test for a return of the cancer. It shows the liver, lungs, glands and the belly lining.
An endoscopy looks at the join made during the operation and, if part of the stomach was kept, at the stomach left behind. A biopsy is taken from anything that looks unusual. A narrowing at the join is often only scar, but it is always biopsied to be sure.
Tumour markers are proteins in the blood that some stomach cancers make. The usual ones are CEA, CA 19-9 and CA 72-4.
Markers help only if they were raised before treatment. Then a rise later can be an early sign of return, often before the scan shows it.
PET-CT is not a routine follow-up test. It is used when a CT scan or a rising marker raises a question that the CT alone cannot answer.
It is good at showing glands and spread far away. It is weaker at showing very small spots on the belly lining. It also costs much more, so it is used where it will change the decision.
Some very early stomach cancers are removed through the endoscope, without an operation. The rest of the stomach stays, and a new early cancer can start elsewhere in it.
These endoscopies use high-definition scopes and special dyes or light to show small flat changes. Treating H. pylori, if present, is part of the plan. You can read more on the post about treatment of early stomach cancer.
With no stomach left, the CT scan does most of the work. Endoscopy is done to check the join between the food pipe and the small bowel.
A return at the join is uncommon when the cut edges were clear. Food sticking, or a hard time swallowing, still needs an endoscopy to look.
Life without a stomach brings its own checks. Vitamin B12 must be given by injection or high-dose tablets for life. Iron, calcium and vitamin D are checked yearly, and bone strength may be tested. Small, frequent meals help weight hold steady.
When the lower part of the stomach is removed, a part stays behind. Bile can flow back into it over the years and damage its lining.
So the stomach that remains is checked by endoscopy, with biopsies of the join and the remnant. This continues every 1 to 2 years, even after five years.
The risk is higher after the older Billroth II type of join. More on cancer in an operated stomach is on the post about stomach cancers that need a different plan.
Not every change on a scan is cancer. These situations come up often, and each has a sensible next step:
The aim is to avoid both missing a return and starting treatment for a shadow. A short wait with a repeat test is often the safest step.
Some people receive immunotherapy medicines as part of their treatment. Follow-up after these has a few extra points.
After five years with no return, people with an early, lower-risk cancer can move to a yearly visit, with scans and endoscopy every 2 to 3 years.
People who had the diffuse or signet ring type stay on yearly checks up to ten years. This type can return late, on the belly lining.
Cost and travel matter to many families. A clear plan, agreed at the start, avoids both too many tests and too few. Ask which tests are due at each visit, and which can wait.
Do not wait for the next date if any of these appear:
Most people are seen every 3 to 6 months for the first two or three years, then once a year up to five years. The exact plan depends on how advanced the cancer was on the final report.
No. A CT scan of the chest, belly and pelvis is done at set times, usually every 6 months at first and then once a year. In between, the visit is a talk, an examination and blood tests.
Not on its own. Many stomach cancers never raise the markers. A normal marker is reassuring only together with a clear scan and a person who is eating well and holding weight.
Yes, from time to time. It checks the join between the food pipe and the small bowel. It is needed sooner if food sticks or swallowing becomes hard.
Vitamin B12 for life, by injection or high-dose tablets. Iron, calcium and vitamin D are checked and given as needed. Small, frequent meals help keep weight steady.
After five years with no return, visits for a lower-risk cancer can be spaced to once a year or less. The diffuse or signet ring type is usually followed yearly up to ten years.
