Multidisciplinary Prehabilitation and Postoperative Rehabilitation in Patients Undergoing Resection of Colon Cancer (ONCOFIT)

Multidisciplinary Prehabilitation and Postoperative Rehabilitation for Avoiding Complications in Patients Undergoing Resection of Colon Cancer: ONCOFIT Study

ONCOFIT is a randomized clinical trial with a two-arm parallel design aimed at determining the influence of a multidisciplinary prehabilitation + postoperative program on post-surgery complications in patients undergoing resection of colon cancer. This intervention will include supervised physical exercise, dietary behavior change, and psychological support comparing its influence to the standard care.

Study Overview

• Status: Active, not recruiting
• Conditions: Postoperative Complications; Colon Cancer
• Intervention / Treatment: Other: Usual Care; Behavioral: Prehabilitation program (4 week before the surgery); Behavioral: Postoperative program (12 week after the surgery)

Detailed Description

Nowadays, colon cancer is one of the most common types of tumors worldwide being surgical resection the elective therapy for its curation. However, a surgery is a stressful procedure that may involve several postoperative complications. Risk factors for such undesirable events are closely related to lifestyle issues including decreased physical activity levels or dietary unhealthy habits. Recent studies have suggested that the implementation of multidisciplinary prehabilitation and postoperative interventions based on lifestyle habits may be a potential strategy for accelerate post-surgical recovery. To the best of our knowledge, the combined effect of a Prehabilitation + Postoperative Programs (PPP) on post-surgery complications and functional capacity of patients undergoing resection of colon cancer remains unclear. ONCOFIT is a randomized clinical trial with a two-arm parallel design aimed at determining the influence of a multidisciplinary PPP on post-surgery complications in patients undergoing resection of colon cancer. This intervention will include supervised physical exercise, dietary behavior change, and psychological support comparing its influence to the standard care. Primary and secondary endpoints will be assessed at baseline, at preoperative conditions, at the end of the PPP intervention and 1-year post-surgery, including: post-surgery complications, prolonged hospital length of stay, readmissions and emergency department call, functional capacity, patient' reported outcome measures targeted, anthropometry and body composition, clinical markers, physical activity levels and sedentariness, dietary habits, others unhealthy habits, sleep quality and fecal microbiota diversity and composition. Considering the feasibility of the present intervention in a real-life scenario, ONCOFIT will contribute to the standardization of a cost-effective strategy for preventing and improving health-related consequences in patients undergoing resection of colon cancer with an important clinical and economic impact, not only in the scientific community but also in the clinical practice.

Cost-effectiveness analysis	We will calculate the ratio of incremental costs and incremental clinical benefits as the additional expenditure required to generate an additional unit of benefit, expressed as cost per quality-adjusted life-year (QALY) added, and calculated as CE = (Cost2-Cost1)/(QALY2-QALY1). EuroQol 5-dimension 5-level (EQ-5D-5L) will be used for QALY estimation.
