Elimination of Peritoneal Tumor Cells With Extensive Peritoneal Lavage During Surgery in Patients With Gastric Cancer

Stopped: Prematurely halted after interim data analysis

Germany30 participantsStarted 2011-02

Plain-language summary

A Japanese study showed that the additional use of an "Extensive Intraperitoneal Lavage" (EIPL), i.e. an extensive washing of the abdominal cavity with water, during surgery for gastric cancer can lead to a significant increase in survival. However, the study was confined to patients in whom upon commencing surgery, free peritoneal tumor cells were detected, which is only a small fraction of patients. The primary objective of our study is to assess in all patients undergoing removal of the stomach and adjacent lymph nodes for stomach cancer, if EIPL can eliminate free peritoneal tumor cells which have been present at the beginning of the surgery or after the stomach and lymph node removal. Secondary objectives are to assess how often free peritoneal tumor cells occur in patients with stomach cancer, how often surgical resection itself leads to a release of tumor cells, the safety of the EIPL procedure, and disease-free and overall survival of patients undergoing EIPL. Based on the outcome of this japanese study we want to test with special laboratory methods why this lavage leads to a better outcome. Specifically, the trial will test the hypotheses that a) lymph node dissection causes a release of tumor cells in the abdominal cavity, and b) EIPL eliminates free peritoneal tumor cells.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Adenocarcinoma of the stomach or cardia (Siewert Type 2 or 3), treated in curative intent with a gastrectomy or subtotal gastrectomy, and D2 lymphadenectomy. * Adjuvant and neoadjuvant therapy do not constitute exclusion criteria * Written informed consent * Age ≥ 18 years Exclusion Criteria: * Histologically proven peritoneal carcinomatosis (biopsies of macroscopically suspicious findings must be taken at the beginning of the operation and be analyzed immediately by fresh frozen section) * Histologically proven distant metastases * Other medical causes precluding EIPL (e.g. critical condition throughout the surgery with the need to terminate the operation as soon as possible)

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
