About this study

Official title: Prospective Study of the Effect of Perioperative Immunonutrition on the Immune Host Defense and the Phagocytic and Bactericidal Activity of Blood Platelets in Gastric Cancer Patients.

Perioperative immunonutrition in gastric cancer patients can reduce perioperative morbidity and may improve quality of their life. Patients with gastric cancer will be divided into four groups depending on the type of artificial nutrition. Group I (enteral feeding) and II (enteral feeding and parenteral nutrition with glutamine) will be administered nutritional therapy during the postoperative period, group III (oral arginine) and IV (parenteral immunonutrition) patients will be treated nutritionally both prior to and after the surgery. The lymphocytes and their subpopulations, interleukin IL-1B,-6,-23, and the phagocytic, and bactericidal activity of blood platelets will be determined before and after nutritional therapy.

Read the detailed description

Surgical treatment of gastric cancer is associated with a high risk of perioperative complications. Morbidity of cancer patients increases in concert with the clinical stage of the malignancy. It is postulated that a reduction in perioperative morbidity and improved quality of life of patients with advanced gastric cancer can be achieved by proper preparation to surgery, among others. One of such methods is the implementation of immunostimulating nutritional therapy during the perioperative period.The stage of cancer will be graded according to TNM classification. The patients will be randomly assigned to four clinical groups based on the type of nutritional therapy implemented.

Conditions: Gastric Cancer
Being tested: Early postoperative enteral nutrition, based on standard elementary diet (Peptisorb), glutamine, oral diet enriched with arginine (Cubitan), Perioperative parenteral immunonutrition (Dipeptiven, Omegaven)

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Early postoperative enteral nutrition, based on standard elementary diet (Peptisorb)Dietary supplement
Early postoperative enteral nutrition with standard elementary diet (Peptisorb), will start 20 hours post-surgery. The initial flow rate will be 8 ml/h, which will increase gradually, with the volume doubled every 24 hours, up to 100 ml/h. The enteral nutrition wil be continued for six days. During the initial five days post-surgery, the patients will be additionally supplemented parenterally via peripheral veins (commercially available two-chamber bag for peripheral access with 480 kcal of energetic value and 5.7g of N contained in standard amino acids).
glutamineDrug
The nutritional therapy of group II patients will start post-surgery. It will be based on early enteral nutrition with elementary diet (Peptisorb) with simultaneous parenteral nutrition with two-chamber bag with 480 kcal energetic value and 5.7g of N contained in standard amino acids administered via peripheral veins. Additionally, glutamine (100 ml of Dipeptiven) will be added to the two-chamber bag. The parenteral nutrition will be administered for five days.
oral diet enriched with arginine (Cubitan)Dietary supplement
Preoperatively, group III patients will be given commercially available oral diet enriched with arginine (Cubitan, 1 package 3 times per day). Additionally, they were administered commercially available two-chamber bag with 480 kcal energetic value and 5.7g of N in standard amino acids via peripheral access. The duration of pre-operative preparatory phase ranged between 5 and 10 days (8 days on average). Enteral nutrition with commercially available arginine-containing diet (Cubison) will start 20 hours post-surgery at an 8 ml/h flow rate; the rate will increase gradually, with the volume doubled every 24 hours, up to 100 ml/h and continued for six days. Simultaneously, commercially available two-chamber bags for peripheral access with composition identical to that used preoperatively will be administered via peripheral veins for five days.
Perioperative parenteral immunonutrition (Dipeptiven, Omegaven)Drug
Nutritional therapy of group IV will based on intravenous preparations. Two-chamber bags with 480 kcal energetic value and 5.7 g of N in standard amino acids were administered preoperatively. A solution of glutamine (Dipeptiven, 100 ml) and ω3-fatty acids (Omegaven, 100 ml) will be added to the bags. The duration of pre-operative preparatory phase ranged between 5 and 10 days (8 days on average). Enteral nutrition with elementary commercially available diet (Peptisorb) will be begun 20 hours post-surgery; it will start at an 8 ml/h flow rate and increased gradually, with the volume doubled every 24 hours, up to 100 ml/h. The enteral nutrition was continued for six days. During the initial five days post-surgery, the patients will be additionally supplemented parenterally via peripheral veins; similarly to the preoperative period, the content of two-chamber bag for peripheral access enriched with glutamine and ω3-fatty acids will be administered for five days.

What is being measured

The primary outcome is the main question the study is designed to answer.

Phagocytic activity of blood platelets in gastric cancer patients.
Platelet count and phagocytic activity of thrombocytes will be examined twice in each patient. Blood samples for laboratory tests will be drawn prior to surgery and nutritional therapy and 12 days after the surgery. Thrombocyte count will be determined using ADVIA 120 haematological analyser. Phagocytic activity of blood platelets will be determined against Staphylococcus aureus ATCC 6538P bacterial strain. It expresses as the fraction of phagocytizing platelets and the phagocytic index. The fraction of phagocytizing platelets corresponds to the percentage of phagocyting thrombocytes per 1000 consecutive cells of this type. The phagocytic index represents the ratio of phagocytized bacteria per 100 phagocytic platelets.
Measured: Participants will be followed for the duration of hospital stay, an expected average of 3 weeks

Questions about this trial

What is this clinical trial studying?

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 17 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Poland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Zbigniew Kamocki, MD PhD (+48606452246, zkamocki@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phagocytic activity of blood platelets in gastric cancer patients. (time frame: Participants will be followed for the duration of hospital stay, an expected average of 3 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01704664, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
