Can a less extensive stomach surgery preserve appetite better?
NCT ID NCT06243757
First seen Jul 22, 2026 · Last updated Jul 23, 2026 · Updated 1 time
Summary
This study compares two minimally invasive surgeries for cancer at the top of the stomach or where the stomach meets the esophagus: removing only the upper part (proximal gastrectomy) versus removing the entire stomach (total gastrectomy). The goal is to see which approach leads to better appetite and fewer digestive symptoms in the year after surgery. Participants will complete symptom questionnaires before and at several points after their operation.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- minimally invasive proximal gastrectomy (MIPG) versus minimally invasive total gastrectomy (MITG)
- What this could lead to
- If one surgery leads to better appetite and fewer symptoms, it could become the preferred option for patients with upper stomach cancer.
- What could go wrong
- This is a very small pilot study with only 4 participants, so results may not apply broadly. Surgery type is chosen as part of routine care, not randomly assigned.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
The initial contact with the potential participants will be conducted either by the treatment team, investigator or the research staff working in consultation with the treatment team. Participants will be screened in gastric and mixed tumor surgery clinics on the 5th floor of the MSKCC 53rd Street outpatient clinic building. The investigator/research staff will review portions of the medical record to determine if they are eligible. Participants who are eligible will be approached by study personnel in clinic. The study will be explained to participants by the study personnel and interested participants will be given the consent form to review.
