Care Coach-led Integrated Palliative Surgical Oncology and Rehabilitation Care Model for Advanced Cancer Patients

* Patients will receive the current standard of care based on their surgeon's usual clinical practice. * Additionally, patients will receive the Care Coach-led Palliative Surgical Oncology (PSO) intervention during all phases of their surgical journey. * After pre-surgery consultations, care coaches will conduct Serious Illness Conversations (SIC) and focus on exploration of patients' hopes and worries, critical functions, social setup, and identification of a healthcare proxy. The SIC will also be conducted at 1, 3, 6, 9 and 12 months post-surgery. * The Care coach will also screen for psychological and emotional needs using the Distress Thermometer and Problem List (pre-surgery and at 1, 3, 6, 9 \&12 months post-surgery). This will help to identify areas requiring palliative interventions such as symptom management or psychosocial support and for follow-up actions to be taken. * ACP will also be offered at each timepoint to those who have yet to do so.

• Patients will receive services from a dedicated rehabilitation service comprising of a Rehabilitation Physician, Physiotherapist, and Dietician. * Pre-surgery: Patients will be triaged based on their frailty \[Clinical Frailty Scale (CFS)\], malnutrition risk \[Malnutrition Universal Screening Tool (MUST)\], and physical function \[5-sit-to-stand (5-STS)\] and will receive preventive rehabilitation interventions tailored to their functional needs. * During surgical admission: The rehabilitation physician will review the progress of patients and refer them to a dietitian if needed. Patients may be followed-up by a rehabilitation physician one-month post-discharge and referred to a physiotherapist if required. * Post-surgery: Patients will be screened by care coaches for health needs using the EQ-5D-5L at months 3, 6, 9 \& 12 post-surgery who will make referrals to a rehabilitation physician, nurse and psychologist, as needed.
