An observational study in Gastric Cancer (GC), HIPEC and Peritoneal Metastases From Gastric Cancer, sponsored by Ukrainian Society of Clinical Oncology. Recruiting at 1 site in Ukraine. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2026-01-13.

The study investigates the outcomes of hyperthermic intraperitoneal chemoperfusion (HIPEC) in combination with curative-intent gastrectomy in resectable locally-advanced and limited-metastatic (low peritoneal cancer index) gastric cancer.
Several recent studies showed that near-perfect curative-intent R0 surgical technique combined with systemic chemotherapy or even immunotherapy may not always be enough to eliminate microscopic deposits or eliminate peritoneal dissemination in locally advanced gastric cancer or low peritoneal cancer-index (PCI) tumors. The risk of peritoneal dissemination is especially high for T4 tumors, for those with cytologically positive peritoneal washings. Moreover, the risk of peritoneal relapse in low PCI tumors is remarkably high. Combination of surgery and intraperitoneal chemotherapy aims to minimise the risks of the aforementioned peritoneal progression. In the study investigators perform curative surgery followed by single dose of hyperthermic intraperitoneal chemotherapy (HIPEC).
3,399 studies on the registry are indexed under Stomach Neoplasms; 992 are open to participants now.
This study's planned enrollment of 200 is below the median of 278 across 790 observational studies indexed under Stomach Neoplasms.

The study population will consist of adult patients receiving care at oncological centers in Ukraine who meet all predefined eligibility criteria for this study. Investigators include individuals with for which Gastrectomy+HIPEC is considered an accepted or potentially beneficial treatment option according to national and international clinical guidelines. Participants will be recruited from tertiary surgical oncology hospitals and specialized cancer institutes across Ukraine.

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.
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).
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.
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.
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.
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.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
