PROGAIN Trial in Gastric Cancer Surgery

The PROGAIN Trial : A Randomized Study of Protein-enriched Parenteral Nutrition on Nitrogen Balance and Recovery in Perioperative Gastric Cancer Surgery

Sponsor

Soonchunhyang University Hospital

Enrollment

100 participants

Start Date

Feb 13, 2026

Study Type

INTERVENTIONAL

Conditions

Stomach (Gastric) Cancer

Summary

This randomized study will evaluate whether protein-enriched parenteral nutrition improves early postoperative recovery in patients undergoing gastrectomy for gastric cancer. Participants will be assigned to receive either protein-enriched parenteral nutrition or standard parenteral nutrition during the perioperative period. The primary outcome is nitrogen balance on postoperative day 5. Secondary outcomes include postoperative complications, recovery of oral intake, and short-term changes in nutritional status and body composition.

Eligibility

Min Age: 19 Years

Inclusion Criteria1

  • Adults aged 19 years or older scheduled to undergo gastric cancer surgery. - Patients who have provided written informed consent to participate in this study.

Exclusion Criteria13

  • Patients with uncontrolled severe systemic diseases (e.g., decompensated diabetes, cerebrovascular event within the last 6 months, sepsis, heart failure).
  • Patients who have received intravenous parenteral nutrition within 7 days prior to randomization.
  • Patients with severe metabolic abnormalities confirmed by preoperative laboratory tests, including but not limited to:
  • Triglyceride > 400 mg/dL
  • AST or ALT > 3 x Upper Limit of Normal (ULN)
  • Total Bilirubin > 3 x ULN
  • Serum Creatinine > 2 x ULN
  • HbA1c > 9.0%
  • Potassium < 3.0 mEq/L or > 6.0 mEq/L
  • Calcium > 12.5 mg/dL
  • Sodium > 155 mmol/L
  • Magnesium > 3.0 mg/dL
  • Patients deemed inappropriate for participation in this clinical trial by the investigator.
