Postoperative Prognosis Management Service Based mHealth for Colon Cancer Patients

Study Overview
=================
Brief Summary
-----------------
Recently, the use of mobile health is increasing for the purpose of managing prognosis such as recurrence, survival and quality of life by using a wearable smart band and a smartphone application. In the era of the 4th revolution, mobile health for the purpose of comprehensive prognosis for cancer patients is becoming a very good tool. It is possible to confirm the clinical significance of short-term and temporary health care through a mobile application and a smart band during the treatment process for cancer patients, but the study is insufficient to generalize the number of subjects. Therefore, for colon cancer patients who need prognosis management after surgery, we will investigate the effect of a mobile application using a smart band which has a modular structure reflecting the treatment method and treatment process after surgery. This study targets patients who underwent prostate cancer surgery. An intervention group (App+IoT device) uses a smart care application for 12 months. This application was tailored for prostate cancer patients and created by reflecting the treatment process after surgery. And they also uses a wearable smart band for 12 months. Control group is provided general education through the hospital brochure. Evaluation will be conducted 2-3days after surgery (before discharge), and at 1, 3, 6, and 12 months after surgery.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change of body composition (weight, kg) | According to time frame with between-group and within group, trends will be found. | Enrollment (postoperative 2-3days), postoperative 1month, 3month, 6month, 12month | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change of Quality of life (EORTC-QLQ-C30) | comparison between groups in change of quality of life between baseline (postoperative 2-3days) and postoperative day 6 months This questionnaire contains 30 items regarding general health status, five functional scales (ie, physical, role, cognitive, emotional, and social functioning), three symptom scales (ie, fatigue, pain, and nausea or vomiting), and six single-item scales (ie, dyspnea, appetite loss, constipation, diarrhea, financial difficulties, and insomnia). Each scale includes a different set of items, which are calculated using specific coding procedures. Higher scores for the general health status and the functional scales imply positive results, whereas the symptom and the single-item scales are interpreted inversely. | Enrollment (postoperative 2-3days), postoperative 1month, 3month, 6month, 12month | 
| Pain (Numeric rating scale, NRS) | According to time frame with between-group and within group, trends will be found. NRS score (11 point scales) ranges from 0 (no pain) to 10 (possible to image maximum pain). Higher score indicates higher pain. | Enrollment (postoperative 2-3days), postoperative 1month, 3month, 6month, 12month | 
| Change of Quality of life (EORTC-QLQ-C29) | The Multi-Attribute Scale Analysis module evaluates four scales to evaluate urine frequency, stool leakage, stool consistency, and body image, as well as other common problems after treatment for colorectal cancer. | Enrollment (postoperative 2-3days), postoperative 1month, 3month, 6month, 12month | 
| Physical activity (IPAQ-SF) | According to time frame with between-group and within group, trends will be found. There are two forms of output from scoring the IPAQ. Results can be reported in categories (low activity levels, moderate activity levels or high activity levels) or as a continuous variable (MET minutes a week). MET minutes represent the amount of energy expended carrying out physical activity. Higher METs or category level indicates higher physical activity. | Enrollment (postoperative 2-3days), postoperative 1month, 3month, 6month, 12month | 
| Grip strength | According to time frame with between-group and within group, trends will be found. Using a grip dynamometer, take three measurements on both hands. Higher value (kg) indicates higher grip strength. Since this test is judged to have a mild effect of abdominal pain after surgery, it is evaluated from enrollment. | Enrollment (postoperative 2-3days), postoperative 1month, 3month, 6month, 12month | 
| Lower extremity muscle endurance (30seconds chair stands test) | According to time frame with between-group and within group, trends will be found. It measures the number of times you sit and stand up in a chair for 30 seconds. Higher value (number) indicates higher lower extremity muscle endurance. It is judged that the 30seconds chair stands test will be difficult due to abdominal pain after surgery, so the evaluation is performed only at the other F/U points excluding the enrollment date. | postoperative 1month, 3month, 6month, 12month | 
| 2 Minute walk test (2MWT, evaluation of cardiopulmonary endurance) | According to time frame with between-group and within group, trends will be found. The 2MWT is a measurement of endurance that assesses walking distance over two minutes. It is judged that the 2MWT will be difficult due to abdominal pain after surgery, so the evaluation is performed only at the other F/U points excluding the enrollment date. | postoperative 1month, 3month, 6month, 12month | 
| Nutrition assessment (Mini-nutrition assessment, MNA) | According to time frame with between-group and within group, trends will be found. The short form of the MNA (MNA-SF) is a screening tool consisting of six questions on food intake, weight loss, mobility, psychological stress, or acute disease, the presence of dementia or depression, and body mass index (BMI). The maximum score for this part is equal to 14. A score equal to or higher than 12 indicates that the subject under study has an acceptable nutritional status thus excluding malnutrition and/or malnutrition risk, meanwhile, a score ≤ 11 implicates to proceed with the complete version of the MNA (MNA-LF). This version consists of 12 additional items and provides a maximum possible overall assessment of 30 scores: a score of fewer than 17 indicates malnutrition, a score of 17-23.5 indicates a risk for malnutrition and a score higher 23.5 indicates well-nourishment. | Enrollment (postoperative 2-3days), postoperative 1month, 3month, 6month, 12month | 
| LARS(Low Anterior Rectal Resection Syndrome) score questionnaire | Developed under the leadership of S. Laurberg to initially assess the severity of symptoms after anterior resection of the rectum for cancer, it can be used to assess the disability caused in multiple situations (isolated anorectal irradiation, rectosigmoid resection, prolapse surgery…). It is correlated with the quality of life. | Enrollment (postoperative 2-3days), postoperative 1month, 3month, 6month, 12month | 
| The Wexner score | This score, very easy to use, is most frequently used when a summary assessment of the severity of anal incontinence is necessary. | Enrollment (postoperative 2-3days), postoperative 1month, 3month, 6month, 12month |
