Drain fluid may hold key to immunotherapy response in gastroesophageal cancer
NCT ID NCT05338060
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study collected surgical drain fluid and blood from 10 patients who had surgery for stomach or esophageal cancer. Researchers analyzed these samples for molecular markers that might predict how well a patient would respond to immunotherapy. The goal was to establish a method for collecting and studying these fluids, not to test a new treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help identify which patients with gastroesophageal cancer are most likely to benefit from immunotherapy after surgery.
- What could go wrong
- This was a very small, early study (10 participants) focused on collecting samples, not testing a treatment. The findings may not lead to a usable test or apply to larger populations.

Inclusion Criteria: * Patients undergoing esophagectomy or gastrectomy for gastroesophageal cancer. * Adult males and females at least 18 years of age * Ability to complete testing in the protocol and attend study visits * Able and willing to consent to protocol * Adequate organ function Absolute Neutrophil Count (ANC) ≥1.5 x 103/μL Platelets ≥100 x 103/μL Hemoglobin \>9.0 g/dL Total Bilirubin (\</= 2.0 mg/dl at time of Y90 radioembolization) AST/ALT ≤5 x upper limit of normal Albumin \>3 g/dL Creatinine ≤1.5 mg/dL Exclusion Criteria: * Female patients who are pregnant or breast-feeding * Concomitant illness that would prevent adequate patient assessment or in the investigators' opinion pose an added risk for study participants. * Life-threatening intercurrent illness * Anticipated poor compliance * Prisoners or subjects who are involuntarily incarcerated * Persons with decisional incapacity/cognitive impairment * Any history or evidence of severe illness or any other condition that would make the patient, in the opinion of the investigator unsuitable for the study * Subject is enrolled in a separate interventional clinical trial
