Description of intervention(s) / exposure
Intervention group will consume 1 immunonutrition supplement (178mL) 3 times day day for 5 days prior to their surgery.

For one immunonutrition supplement (178mL)

Key Active Ingredients:
Arginine - 4.2g
Omega-3 Fatty Acids

Comparator / control treatment
Control group will consume 3 nutrition supplements each day for five days. Together, they will be approximately equivalent in protein and energy as the immunonutrition supplements. They will drink 3 Resource Protein (200mL each) each day and repeat this for five days. Please see attachment for active ingredients, dose and protein and energy content (viewed on the ANZCTR registry only).

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Each patient will be randomly allocated to the intervention or control group in the preadmission clinic. A piece of paper with either intervention group or control group written on it will be placed in a sealed, opaque envelope and the pelvic exenteration nurse will select at random an envelope for each patient. She will then open the envelope for each patient and allocate them to the appropriate group.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
1. Permuted block randomisation

Brief summary
The purpose of this study is to determine if immunonutrition prior to pelvic exenteration surgery for people with cancer decreases complications, length of hospital stay and immune markers after their surgery.

Who is it for?

You may be eligible to join this study if you are aged 18 years or above, and are scheduled to undergo pelvic exenteration surgery for cancer.

Study details -

Participants in this study will be randomly (by chance) allocated to one of two groups. Participants in one group will consume 3 immunonutrition supplements (known as Impact Advanced Recovery) each day for 5 days prior to their surgery. Participants in the other group will instead consume 3 nutrition supplements with equivalent protein and energy as the immunonutrition supplements (3 x Resource Protein) each day for 5 days prior to their operation.

All participants will be monitored for up to 3 months post hospital discharge for any post-operative complications, such as infectious or non-infectious complications and immune markers.
