About

The survey is a phase IV, prospective randomized clinical trial to determine whether an immunomodulating nutrient-enriched diet compared to a standard diet can improve nutritional status and reduce postoperative infection and surgery-induced immune suppression in patients with gastric cancer or GIST undergoing major surgery in a single medical center.

Full description

Primary Objective:

1. The primary end points:

   To evaluate the effect of immunomodulating diets on the postoperative inflammatory response: including interleukin (IL)-6, C-reactive protein (CRP), and tumor necrosis factor-α (TNF-α).

2. Secondary Objectives:

(1). Biochemistry parameters: glucose,blood urine nitrogen, creatinine, aspartate aminotransferase, alanine aminotransferase, triglycerides, cholesterol, low-density lipoprotein, high-density lipoprotein, sodium, and leukocyte count.

(2). Nutritional status: albumin, prealbumin, BMI (3). Adverse events (4). Clinical outcomes: postoperative complications, time to first bowel action and length of hospital stay after surgery.

Number of Subjects: Eligible patients will be randomized in 2 arms in the ratio of 1:1, to reach 15 patients at least in each.

Plan of the Study:

1. This is a randomized, comparative, double blinded study in 2 arms.
2. Study Schedule Study date: the time getting approval letter issued by both regulatory authority and institutional review board (IRB). Duration of the study: 5 years.
3. Duration of Treatment: Treatment was administered before curative surgery for gastric adenocarcinoma or gastric GIST, and postoperative day 5-14 or to discharge whichever occurred first, or consent withdrawal during any time of the study, when the patient would be withdrawn.

34 participants in 2 patient groups

immunomodulating nutrients enriched diet

Experimental group

Description:

Patients received oral feeding with an ordinary diet plus 400 mL/day (400 kcal/day) of the immunomodulating nutrients enriched diet for 3-5 days before curative surgery for gastric adenocarcinoma or gastric GIST. On postoperative day 3, enteral nutrition (EN) was initiated with 5% glucose in water at a rate of 20 mL/h. On postoperative day 4, patients received a semi-liquid diet plus 400 mL/day (400 kcal/day) of the immunomodulating nutrients enriched diet. From postoperative day 5-14 or to discharge whichever occurred first, 1200 mL/day (1200 kcal/day) of the interventional diet was administered, and an oral soft diet was also administered if no postoperative complications developed and if oral feeding was not prohibited.

Treatment:

Dietary Supplement: immunomodulating nutrients enriched diet

standard diet

Active Comparator group

Description:

Patients received oral feeding with an ordinary diet plus 400 mL/day (400 kcal/day) of the standard diet for 3-5 days before curative surgery for gastric adenocarcinoma or gastric GIST. On postoperative day 3, EN was initiated with 5% glucose in water at a rate of 20 mL/h. On postoperative day 4, patients received a semi-liquid diet plus 400 mL/day (400 kcal/day) of the interventional diet. From postoperative day 5-14 or to discharge whichever occurred first, 1200 mL/day (1200 kcal/day) of the standard diet was administered, and an oral soft diet was also administered if no postoperative complications developed and if oral feeding was not prohibited.

Treatment:

Dietary Supplement: standard diet
