Description of intervention(s) / exposure
Other interventions - Pharmacogenomic optimisation of anaesthetic medications

Experimental: Pharmacogenomic group - The perioperative (anesthetic and postoperative pain management) plan for each patient will be determined preoperatively by the treating anesthesia team. Thereafter, the pharmacogenomic results of the patient will be released and a personalised anesthetic plan formulated based on international pharmacogenomic guidelines. The treating anesthesia team will then modify the perioperative care plan based on the patients' pharmacogenomic results and the international pharmacogenomic guidelines.

No intervention: Control group - Perioperative care will be managed according to current 'standard care' practice at Peter MacCallum Cancer Centre.


Other interventions: Pharmacogenomic optimisation of anaesthetic medications
