Description of intervention(s) / exposure
Patients included in this substudy will be recruited from the PRIORITY trial (Preoperative exercise for patients undergoing major abdominal cancer surgery). PRIORITY is an NHMRC-funded multicentre randomised controlled trial, investigating primarily the effects of a structured preoperative exercise program on in-hospital complications following major abdominal cancer surgery. For complete details regarding the PRIORITY trial, please see registration ACTRN12621000617864.

This substudy will collect plasma biomarkers from a sample of the PRIORITY cohort, intending to recruit 144 patients for the purposes of this study. The first 144 patients recruited to PRIORITY will be invited to participate in this substudy. Biomarkers will be collected at the following timepoints: (i) within the week preceding planned surgery, and (ii) postoperatively on each day for the first 4 days following surgery. We will also screen for delirium before and after surgery and assess cognition at baseline and at 1 year following surgery.
Intervention code [1] 322151 0
Not applicable
Comparator / control treatment
Participants randomised to the control arm of the parent trial, PRIORITY, will receive no exercise intervention or advice. They will receive all other standard elements of preoperative care delivered to patients undergoing major abdominal cancer surgery. The participants randomised to the control arm in the PRIORITY trial will be the control arm for this observational sub-study.

Statistical methods / analysis
Differences in postoperative inflammation as measured by CRP at baseline and for the first 4 days following surgery will be compared between the exercise group and control group using a mixed-effects model. 95 percent confidence intervals will be calculated. For the primary outcome, a p-value of <0.05 will be considered statistically significant
