Although small studies are supportive of multimodal interventions, there are insufficient data to make a conclusion about the integration of prehabilitation in GI cancer surgery as a bundle of care. Larger, prospective trials, utilizing uniform objective risk stratification and structured interventions, with predefined clinical and health economic end points, are required before definitive value can be assigned to prehabilitation programs.

In summary, both the limits of agreement and bias between the measured and DASI-predicted pVO were substantial. The DASI-predicted pVO based on patient's assessment of their functional status could not be considered a reliable surrogate of measured pVO during CPET for the population of patients pending major cancer surgery and cannot, therefore, be used as a triage tool for referral to CPET centres for objective risk assessment.

HighlightsBrachial arterial catheterisation is a safe and reliable procedure with a low risk of serious complications.Brachial arterial catheters provide a more accurate reflection of central aortic arterial pressure compared to their radial counterparts.In adults, brachial artery catheter related complications can be minimized by using smaller gauge catheters.Point of care ultrasonography can enhance diagnostic and procedural accuracy compared to a “blind-bedside” procedure.Postoperative neurological monitoring after brachial line catheterization should be routinely performed for timely identification and management of catheter complications.
