Can custom vitamin pills fix nutrient gaps after stomach or esophageal cancer surgery?
NCT ID NCT05281380
First seen Sep 04, 2026 · Last updated Sep 04, 2026
Summary
This study tests whether tailored vitamin and mineral supplements can correct nutrient deficiencies that often follow surgery for esophageal or gastric cancer. Researchers will enroll 107 adults who had either an esophagectomy or a (sub-)total gastrectomy for cancer and show no signs of recurrence. Participants receive one of two custom supplements based on their surgery type, and researchers measure micronutrient levels and quality of life at baseline and after 6, 12, and 24 months. The goal is to see if routine supplementation can improve nutritional status and daily well-being after these major operations.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Tailor-made vitamin and mineral supplements, one for patients who had esophagectomy and one for those who had (sub-)total gastrectomy
- What this could lead to
- If it works, this could point toward a standard way to detect and treat vitamin deficiencies after esophageal or gastric cancer surgery, improving recovery and quality of life.
- What could go wrong
- This is a single-center study with no control group, so results may not apply broadly. Supplements may not fully correct all deficiencies, and benefits for quality of life remain uncertain.
