Peritoneal metastasis is the main factor leading to poor prognosis in patients with gastric cancer or colorectal cancer. Although current systemic treatment regimens can prolong the time to peritoneal metastasis, the long-term survival rate is still poor. This is mainly due to the presence of the peritoneal plasma barrier, which limits the penetration of anti-tumor drugs and thus restricts the efficacy. In contrast, the use of intraperitoneal infusion chemotherapy allows anti-tumor drugs to directly reach the abdominal cavity, exposing metastatic nodules to high concentrations of drugs, and has a significant therapeutic effect on peritoneal metastases, resulting in better therapeutic effects Tumor necrosis factor (TNF) is a small molecule protein secreted by macrophages. There are two types of TNF - α: α and ß. TNF - α is produced by activated monocytes and macrophages, also known as cachectin. TNF - α is produced by activated lymphocytes, also known as lymphotoxins, and the two have similar activity. Previous studies have shown that rmhTNF is safe for intraoperative perfusion in gastrointestinal tumors.
In this real-world study, we will observe the safety and effectiveness of rmhTNF intraperitoneal perfusion in actual clinical settings.
3,399 studies on the registry are indexed under Stomach Neoplasms; 992 are open to participants now.
This study's planned enrollment of 300 is close to the median of 278 across 790 observational studies indexed under Stomach Neoplasms.

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.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
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).
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.
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.
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.
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.
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.
