multidisciplinary prehabilitation and postoperative rehabilitation in patients undergoing resection of colon cancer

Conditions: Colon Cancer; Postoperative Complications

Summary: 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.

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 within 1-year after surgery, 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.

Eligibility criteria:
inclusion criteria: * patients older than 40 years * diagnostic of nonmetastatic colon cancer (i.e., including right, transverse, left, sigmoid, subtotal, total, and hemicolectomy) * not participating in a nutritional/ dietary intervention * being physical inactive (i.e., not to be participating in any physical exercise program in the last 3 months, or performing less than 600 metabolic equivalents (mets)/week of moderate-vigorous physical activity). * to be capable and willing to provide informed consent * not to suffer from any specific condition that may impede testing of the study hypothesis or make it unsafe to engage in the multidisciplinary intervention (i.e., determined by the research staff). exclusion criteria: * medical contraindication for being engaged in an exercise or dietary program. * additional surgery planned within the 3-month intervention * history of another primary invasive cancer * planning to receive adjuvant chemotherapy * to be pregnant * to present any of the following cardiac conditions: (i) myocardial infarction or coronary revascularization procedure within prior 3 months, (ii) uncontrolled hypertension (i.e., systolic ≥180 mmhg or diastolic ≥100 mmhg), (iii) uncontrolled arrhythmias (iv) valvular disease clinically significant, (v) decompensated heart failure or (vi) to suffer from known aortic aneurysm.
