Development of a pre- and re-habilitation protocol for gastrointestinal cancer surgery

Purpose: Surgical resection is the primary curative treatment for gastrointestinal (GI) cancer; however, it is associated with high postoperative complication rates and impaired recovery. Frailty, malnutrition, and sarcopenia increase morbidity and mortality, underscoring the need for perioperative rehabilitation programs. Standardized rehabilitation protocols during the perioperative period are currently lacking in Korea. We aimed to develop an evidence-based rehabilitation protocol for GI cancer patients to enhance postoperative outcomes and facilitate clinical implementation.Methods: A multidisciplinary task force team comprising experts in surgery, clinical nutrition, and rehabilitation medicine conducted a systematic literature search and comprehensive review from 2012 to 2022 to develop a standardized pre- and re-habilitation protocol for GI cancer surgery. The protocol underwent external validation and subsequent refinements before being finalized through expert consensus.Results: The protocol development process was organized into four consecutive phases: keyword selection, literature review and case report form development, initial protocol drafting, and external validation leading to the final version of the protocol. The final version of the rehabilitation protocol is presented in the main text and included as Supplements.Conclusion: This protocol provides a standardized clinical guideline based on the latest evidence-based pre- and re-habilitation strategies and is designed for seamless integration into routine clinical practice. By facilitating proactive rehabilitation interventions, it aims to improve outcomes in GI cancer patients who are at high risk of postoperative complications, functional decline, and malnutrition.
