Comparing minimally invasive surgeries for stomach cancer

Trans-Pacific Multicenter Collaborative Study of Minimally Invasive Proximal Versus Total Gastrectomy for Proximal Gastric and Gastroesophageal Junction Cancers

M.D. Anderson Cancer Center · NCT05205343

This study is testing whether a less invasive stomach surgery helps people with stomach cancer feel better and maintain their appetite compared to a more extensive surgery.

What this trial studies

This study aims to compare the short-term appetite and nutritional outcomes of patients undergoing minimally invasive proximal gastrectomy (MIPG) versus those undergoing total gastrectomy (MITG) for non-metastatic gastric and gastroesophageal junction adenocarcinoma. The primary objective is to determine if MIPG leads to better postoperative appetite levels, which may improve nutritional status and body weight maintenance. Patient-reported outcomes will be assessed using the MD Anderson Symptom Inventory Gastrointestinal Cancer Module and additional questionnaires to evaluate quality of life and correlate appetite levels with fasting ghrelin levels. The study will also investigate safety and oncological outcomes associated with both surgical approaches.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with a biopsy-confirmed diagnosis of non-metastatic gastric or gastroesophageal junction adenocarcinoma scheduled for curative surgery.

Not a fit: Patients with known malabsorption syndromes, narcotic dependence, or those unable to comply with study procedures may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved postoperative appetite and nutritional outcomes for patients undergoing surgery for gastric cancer.

How similar studies have performed: Other studies have shown promising results with minimally invasive surgical approaches, suggesting potential benefits in postoperative recovery and quality of life.
