In short
Stomach cancer is called metastatic when deposits are found on the lining of the abdomen, in the liver, or in lymph nodes far from the stomach.
The main treatment is medicine. Removing the stomach leaves behind disease that already sits outside it, and a trial tested exactly that question.
Four markers on the biopsy tissue decide which medicines are used. They are HER2, PD-L1, the repair markers MMR and MSI, and Claudin-18.2.
An operation is still offered for bleeding, a closed stomach outlet or a hole in the stomach wall. It treats the problem, not the cancer.
Metastatic disease is one stage of the stomach cancer pathway. The full picture, from staging to the operations offered when cancer has not spread, is on the main stomach cancer treatment in Ahmedabad page.
Metastatic means the cancer has settled where a stomach operation cannot reach. A few places account for nearly all of it. Each one shows itself in its own way.
| Where the deposit sits | How it usually shows itself |
|---|---|
| The lining of the abdomen | Fluid in the abdomen, a blocked bowel, or deposits too small for any scan to see |
| The liver | One lump or several, seen on an ultrasound or a CT |
| Lymph nodes far from the stomach | A node felt above the collarbone, or nodes deep behind the abdomen on a scan |
| An ovary | A lump in one or both ovaries in a woman, sometimes found before the stomach tumour |
| Lung or bone | Less common, and usually found on a scan ordered for a new symptom |
The site matters. The lining of the abdomen behaves quite unlike a lump in the liver. It upsets eating and the bowel long before it shows on any scan.
Five steps settle it. The order is chosen with care. The last two change the plan most often.
Cancer cells in the saline wash count as spread, even when every scan looked clear. That one finding moves the treatment from an operation to medicine.
Once deposits sit outside the stomach, taking the stomach out leaves them where they are. That question has been tested, not assumed. One group of patients was given medicine alone. The other had the stomach taken out first, and medicine after it. Each patient had one site of disease that could not be removed. The group who had the operation did no better. They also got less than half the medicine the first group did.
So an operation to take out the cancer is not the first treatment here. The medicine can hold the disease, settle the symptoms and give months of ordinary life. That aim is said plainly before the first cycle. It is not left to be worked out later.
The medicine is not the same for everyone with this diagnosis. Four tests on the biopsy tissue decide it, and all four are asked for at the start.
| Marker | What it is, and what it changes |
|---|---|
| HER2 | A protein carried on the surface of some stomach cancers. Where it is present, a medicine aimed at that protein is added to chemotherapy. |
| PD-L1 | A score for how visible the cancer is to the body’s own defences. A higher score adds immunotherapy to chemotherapy. |
| MMR and MSI | A fault in the repair machinery inside the cancer cell. Cancers carrying that fault answer unusually well to immunotherapy. |
| Claudin-18.2 | A protein found on a group of stomach cancers. Where it is present and HER2 is not, a medicine aimed at it is added. |
HER2 is patchy within one tumour. So several pieces are taken at endoscopy, not one. It can also be lost as the disease changes. That is why a fresh biopsy is sometimes asked for when the first medicine stops working.
Where none of the four is present, chemotherapy on its own is used. A further marker is being studied in trials and may be reported on a gene panel.
Surgery keeps a clear place here. It is offered for three problems. In each one it is aimed at the problem, not at the cancer.
Pain that medicines do not settle has another answer. The nerve bundle behind the stomach can be numbed. That is a needle job done under scan guidance, not an operation.
When the outlet has closed, there are three ways to get food past it. The choice turns on two things. How long it will be needed, and whether an anaesthetic is a fair risk.
| What is done | When it suits |
|---|---|
| A stent placed through the endoscope | A quick answer with no cut. Swallowing usually returns within a day or two. It suits a frail patient, or one whose treatment has limited time to run. |
| A bypass join between the stomach and the small bowel | A durable answer for a patient fit enough for an operation, who is expected to need to eat for many months. |
| A feeding tube placed into the small bowel | Keeps nutrition going while chemotherapy is given. It does not restore eating by mouth, so it is used alongside one of the two above or on its own. |
Food is not a side issue in this disease. Weight loss is the one reason most likely to put off a planned cycle of chemotherapy.
Deposits on the lining need a section of their own. Patients are often told about heated chemotherapy before anyone has explained where it belongs.
The main treatment is still medicine given into a vein. Two other routes exist.
The second route is heated chemotherapy, washed through the abdomen at the end of an operation. That is what HIPEC means, and it sits in a different group. It is for patients whose deposits are few and can all be taken out. It is done only inside a unit that runs a peritoneal programme. It is not part of ordinary treatment for stomach cancer that has spread, and it is not a thing to seek out on its own.
A small, selected group changes direction. For some, the only barrier to an operation was cancer cells in the saline wash. For others, it was a single deposit in one organ. They are looked at again after several months of medicine.
This path is planned with the medical oncologist from the start. It is not decided late. It is not the usual road, and it is never promised at the first visit.
Good symptom control runs beside the medicine from the first week, not after it stops working. Five things come up again and again.
| What troubles patients | What is done about it |
|---|---|
| Pain | Regular medicines by the clock, and a nerve block behind the stomach where pain stays |
| Fluid in the abdomen | Drainage, with a small tube left in place when the fluid returns quickly |
| Being unable to eat | A stent, a bypass or a feeding tube, with a dietitian’s plan behind it |
| Tiredness and low blood counts | Checked before every cycle, with iron or a transfusion where it is needed |
| Fear about what comes next | A supportive care team brought in early, and an honest conversation about the aim |
That team is brought in while the treatment is still working, not at the end. Symptom control is better that way, and fewer patients land in the emergency ward.
| Question | Why it matters |
|---|---|
| Have all four markers been reported on my biopsy? | They choose the medicine, and a missing one narrows the choice for no reason. |
| Was a keyhole look with a saline wash done? | It is the test that finds deposits on the lining, and it changes the plan. |
| What is the aim of this treatment, said plainly? | It should be stated before the first cycle rather than inferred from it. |
| Who do I call when eating stops or pain breaks through? | A named route avoids an emergency admission at midnight. |
It is, but for a problem rather than for the cancer. Bleeding that will not settle, a closed stomach outlet, or a hole in the stomach wall. Taking the stomach out does not treat deposits that already sit outside it.
The markers choose the medicine, and they can only be read on tumour tissue. HER2 in particular is patchy, so several pieces are taken. It is sometimes rechecked when the first medicine stops working.
Heated chemotherapy in the abdomen is for a small, selected group. Their deposits must be few and able to be taken out, and the unit must run a peritoneal programme. It is not part of ordinary treatment for stomach cancer that has spread.
A stent placed through the endoscope usually restores swallowing within a day or two. A bypass join lasts longer, where an anaesthetic is a fair risk and eating will be needed for many months.
In a small, selected group, yes. It needs a fresh scan, and a second keyhole look with a clear saline wash. Everything that can be seen must be removable. It is planned from the start, not offered as a surprise.
