Immunomodulating Nutrients in Perioperative Patients With Gastric Cancer

Primary Objective:

• 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).

• 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:

• This is a randomized, comparative, double blinded study in 2 arms.
• 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.
• 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or to discharge whichever occurred first, or consent withdrawal during any time of the study, when the patient would be withdrawn.
