What Determines Success in Oncological Surgery?
The outcome of oncological surgery is determined by the interaction of patient-related, tumour-related and system-related factors. Understanding these determinants helps patients and clinicians make informed decisions and optimise every aspect of care.
Tumour-Related Factors
Resectability: Whether complete removal of the tumour is technically achievable. Stage: Earlier stages generally achieve better outcomes with surgery. Biology: Grade, histological subtype and molecular markers predict behaviour and chemosensitivity. Margin status: R0 (negative margins) consistently predicts better local control and survival across cancer types.
Surgeon and Centre Factors
Volume: Surgeons and centres performing more procedures have better outcomes. This is particularly true for HIPEC, hepatobiliary surgery, oesophagectomy, pancreatectomy and sarcoma surgery. Specialisation: Dedicated oncological surgeons with subspecialty expertise achieve better results than general surgeons for complex cases. Multidisciplinary team: Cases reviewed and planned by a team produce better decisions than individual surgeon judgement alone. Technology: Robotic surgery, intraoperative imaging and advanced monitoring improve surgical precision and safety.
Patient-Related Factors
Performance status: Functional capacity and co-morbidities affect tolerance of surgery and recovery. Nutritional status: Malnutrition significantly increases complications. Optimising nutrition before surgery (prehabilitation) improves outcomes. Psychological readiness: Mental health and support networks influence recovery. Compliance: Adherence to rehabilitation, adjuvant treatment and follow-up.
Prehabilitation
Pre-operative optimisation — exercise training, nutritional supplementation, smoking cessation and psychological support — in the weeks before surgery has been shown to reduce complications, shorten hospitalisation and improve long-term function.
