This study employs a multicenter randomized controlled trial design, led by the First Affiliated Hospital of Air Force Medical University (Xijing Hospital) in collaboration with 10 other domestic medical institutions, for a total of 11 research centers. The study plans to enroll a total of 120 HER-2-positive gastric cancer patients, including those who drop out, and randomize them into two groups in a 1:1 ratio; The control group received treatment based on gastric cancer stage: Stage IB patients were treated with tegafur monotherapy (40-60 mg orally twice daily based on body surface area, on days 1-14, with a 21-day cycle, for a total of 6 cycles); Stage II patients will receive chemotherapy using either the SOX or XELOX regimen, both of which involve an intravenous infusion of oxaliplatin 130 mg/m² on Day 1, combined with the corresponding oral medications for 14 consecutive days, with a 21-day cycle, for a total of 6 treatment cycles; In addition to the control group's original chemotherapy regimen, the experimental group concurrently received Fuhong Hanlin trastuzumab (National Drug Approval No. S20200019, 150 mg/vial) in addition to the control group's original chemotherapy regimen. The first dose was an 8 mg/kg intravenous loading dose, followed by a maintenance dose of 6 mg/kg, administered concurrently starting on the first day of the first chemotherapy cycle, with each cycle lasting 21 days, and the treatment course consisting of 6 cycles.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
HER2 is a protein, made from the ERBB2 gene, that drives the growth of some cancers. A study may look for a level of the protein, extra copies of the gene, or a particular change in it.
In breast cancer, protein tests are read as HER2-positive, HER2-low or HER2-negative; other cancers use their own rules. Check which test result the study requires.
Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.
The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.
It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.
Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.
Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.
A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.
Stroke symptoms need emergency care at once, even if they go away.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
ECOG performance status
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

Started Jul 2026 (actual). Primary completion is estimated for Dec 2030, 53 months after the start.
Of 295 non-industry phase 2 interventional studies under Stomach Neoplasms, half reached primary completion within 57 months of starting (the median), counting those still running; a quarter within 33 and three quarters within 76. This study's planned 53 months is close to that.
Counting every sponsor, half of 360 studies reached it within 50 months; a quarter within 31 and three quarters within 75.
How these figures are worked out, and which studies are left out of them.
