Colorectal cancer is the third and second most common cancer worldwide in men and women, respectively [Health behaviors, such as physical activity and nutrition, can have positive effects on physical functioning, quality of life, and symptoms related to cancer treatment, such as fatigue among cancer survivors [At present, many cancer survivors rarely use tools to report subjective data such as pain, fatigue, and distress [Mobile health care application has emerged as an encouraging device in managing the clinical course of cancer and improving quality of life and physical performance in cancer survivors. Mobile health is defined as the provision of health services and information through mobile and wireless technologies [To the best of our knowledge, randomized clinical trials that applied a personalized, phase-specific digital health program using mobile application and smart bands to a large number of patients with colorectal cancer have not yet been conducted, especially starting immediately post cancer operation. The primary objective of this protocol is to clarify the effect of mobile application and wearable smart band on skeletal muscle mass increment in patients with colorectal cancer. The secondary outcomes will be improvement in quality of life, enhanced physical fitness level, increased physical activity, diminished pain intensity, decreased severity of the low anterior resection syndrome, weight, and fat mass.
