Stomach Cancer Treatment in China: Two CLDN18.2 Doors, What a Cure Slogan Isn't
Gastric/GEJ cancer in China has two Claudin18.2 doors. Zolbetuximab is first-line with chemo (NMPA 2025). Satri-cel is CAR-T after two prior lines (22 June 2026). About 35% of screened Chinese advanced cases were CLDN18.2-positive. Send HER2 and CLDN18.2 IHC. About 24 hours. No obligation to book.

Quick answer
Stomach / GEJ cancer in China has two Claudin18.2 doors that people mix up. Zolbetuximab (Vyloy) is first-line with chemo for CLDN18.2-positive, HER2-negative advanced disease (NMPA 2025). Satri-cel is CAR-T after two prior lines (NMPA 22 June 2026). About 35% of screened Chinese advanced gastric/GEJ cases were CLDN18.2-positive in Astellas’ approval materials. IARC GLOBOCAN 2024: 341,966 new cases, 248,675 deaths. Stage 4 is treated; the honest goal is often control. Send HER2 and CLDN18.2 IHC. About 24 hours. No obligation to book.
Stomach: standard GI care vs a narrow cell door
Satri-cel is not the default gastric plan. Most files stay on surgery and systemic therapy. The cell door opens only if all four boxes are true.

How stomach cancer is treated, and what to check first
The treatment plan for stomach cancer depends on three things: what kind of tumour it is, how far it has spread, and what tests on the tumour tissue show. Below is a short summary of how Chinese and international guidelines approach this. A doctor proposes the actual plan only after endoscopy, scans and lab tests.
Stomach cancer and GIST are different diseases
Stomach cancer is most often an adenocarcinoma, a tumour of the stomach lining. A gastrointestinal stromal tumour (GIST) grows from other tissue in the stomach wall and is treated by its own rules. Everything below is about adenocarcinoma. If your pathology report says GIST, lymphoma or a neuroendocrine tumour, the approach will be different.
Tumour tests before drug treatment
The diagnosis is made from a biopsy taken during endoscopy. There needs to be enough tissue for both the diagnosis and the marker tests, because the results decide which drugs can be discussed.
HER2
HER2 protein
A protein on the surface of tumour cells. If HER2 is positive, trastuzumab is added to chemotherapy and heart function is monitored.
MMR / MSI
DNA repair status
Shows whether the tumour’s DNA repair system works. If it does not, the tumour may respond better to immunotherapy. Only a small share of patients have this.
PD-L1
PD-L1
Needed if immunotherapy is being discussed: the result shows how well justified it is.
CLDN18.2
Claudin 18.2
Tested before treatment starts if zolbetuximab is being considered. More on this earlier on the page.
If any of these tests have already been done, include the reports: without them a doctor cannot discuss drug options in a meaningful way.
Surgery
Very early cancer with no lymph node involvement can sometimes be removed through an endoscope, without an incision.
Usually at least two thirds of the stomach is removed together with the surrounding lymph nodes. If the tumour is in the lower stomach and there is enough clear margin, part of the stomach is kept. If not, the whole stomach is removed (gastrectomy).
The standard extent of lymph node removal is called D2: nodes are removed not only next to the stomach but also along the major arteries. For accurate staging, at least 16 lymph nodes should be examined. These operations are best done where they are performed often.
Laparoscopic and robotic surgery
Large trials in China, Japan and Korea showed that laparoscopic removal of the lower stomach has long-term results no worse than open surgery. Robotic surgery is also keyhole surgery, but a clear advantage over standard laparoscopy has not been proven. The team’s experience matters more than the approach, so ask how many of these operations they do.
Possible complications
Complications can include bleeding, blood clots, injury to nearby organs and, less often, leaks where the bowel is joined to the oesophagus or the remaining stomach. The risk of dying from the operation is very small; it is higher with more extensive surgery and lower with experienced surgeons. Some people get dumping syndrome: nausea, diarrhoea, sweating and flushing soon after eating. It usually eases over time.
Eating after gastrectomy
The advice is to eat little and often, at least 6–8 small meals a day, avoid drinking large amounts with meals, and weigh yourself regularly. Without a stomach the body absorbs less vitamin B12, iron, folic acid and calcium, so these are checked with regular blood tests. B12 is often given by injection, sometimes for life, and iron as tablets or infusions. A doctor or dietitian chooses the plan.
Chemotherapy before and after surgery
If the tumour has grown deep or has reached the lymph nodes but has not spread to distant organs, chemotherapy usually starts before surgery and continues after it. Combinations of two or three drugs are used; the course before surgery usually lasts no more than 3 months. In a large Chinese trial, chemotherapy before and after surgery gave better results than chemotherapy only after it.
Immunotherapy is sometimes added. In the US, durvalumab with chemotherapy before and after surgery is approved; in China this regimen is not yet registered, and a separate trial is under way.
Drugs when surgery is not possible or the cancer has spread
Most regimens are based on chemotherapy, with an added drug chosen according to the tumour tests.
| Added to chemotherapy | Who it is for | In China |
|---|---|---|
| Trastuzumab | HER2-positive cancer; heart function is monitored | Yes |
| Pembrolizumab + trastuzumab | Needs both positive HER2 and PD-L1 | Yes |
| Nivolumab | HER2-negative cancer; better supported with higher PD-L1 | Yes |
| Pembrolizumab | HER2-negative cancer | Yes |
| Tislelizumab | HER2-negative cancer | Yes |
| Sintilimab | HER2-negative cancer; a Chinese drug | Yes |
| Cadonilimab | Dual antibody; in China’s guideline, regardless of PD-L1 | Yes |
| Retlirafusp alfa | New Chinese drug, for PD-L1-positive cancer | Yes, since 2026 |
| Zolbetuximab | Only for CLDN18.2-positive, HER2-negative cancer | Yes |
Immunotherapy can cause immune-related side effects, so monitoring during treatment is needed. Which option fits your case is decided by an oncologist based on tumour tests, scans and treatment history.
For a free case review, send your endoscopy and pathology reports, any tumour test results (HER2, MMR/MSI, PD-L1, CLDN18.2), CT scans and treatment summaries. A doctor will look at the documents and tell you which options are realistic.

Frequently asked questions
Is there CAR-T for stomach cancer?
Satri-cel is labelled after at least two prior lines for CLDN18.2-positive, HER2-negative advanced gastric/GEJ adenocarcinoma. It is not first-line and not CAR-T for every gastric cancer.
What is zolbetuximab?
An anti-CLDN18.2 antibody. NMPA approved it with chemo as first-line for CLDN18.2-positive, HER2-negative advanced gastric/GEJ cancer. GLOW China-subgroup PFS 8.21 vs 6.8 months.
Are zolbetuximab and satri-cel the same?
No. Antibody plus chemo first-line vs later-line CAR-T. Do not mix them in one SKU.
How many patients are CLDN18.2-positive?
Astellas' China approval materials said about 35% of screened Chinese advanced gastric/GEJ patients. Companion IHC for zolbetuximab uses a high threshold (75% of cells, moderate-to-strong membrane stain).
What did satri-cel's Lancet study show?
PFS 3.25 vs 1.77 months; grade 3 or higher adverse events in 99%; CRS common.
What records should I send?
Endoscopy pathology with HER2 and CLDN18.2 IHC, staging CT, line-by-line drug history.
Is stage 4 curable?
Stage 4 is treated. The honest goal is often control, not a cure slogan.
Do you manufacture cells?
No. Average reply about 24 hours. No obligation to book.
Do I pay before you read the file?
No. Payment required before a file review is a red flag. Average reply about 24 hours. No obligation to book.
How fast do you reply?
About 24 hours. We label the file as labelled care, trial, or marketing. No obligation to book.
How should I eat after gastrectomy, and which vitamins need checking?
Eat little and often, at least 6–8 small meals a day, and avoid drinking large amounts with meals: this lowers the risk of dumping syndrome, which means nausea, diarrhoea, sweating and flushing soon after eating. Without a stomach the body absorbs less vitamin B12, iron, folic acid and calcium, so regular blood tests are needed. B12 is often given by injection, and iron as tablets or infusions. A doctor or dietitian chooses the plan for diet and supplements.
Which tumour tests are needed before chemotherapy or immunotherapy?
Chinese guidelines recommend testing stomach adenocarcinoma for HER2, MMR/MSI, PD-L1 and CLDN18.2. HER2 decides whether trastuzumab is added, PD-L1 how well justified immunotherapy is, and CLDN18.2 whether zolbetuximab can be discussed. The tests are done on biopsy or surgical tissue. If they have already been done, include the reports with your documents for a free case review.
