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 together with 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. As a result of applying a mobile application for health management (nutrition, health education, exercise, etc.) to 203 gastric cancer or colon cancer patients undergoing chemotherapy in the previous study, gastric cancer patients are most interested in health-related education and information.
As such, it was possible to confirm the clinical significance of short-term and temporary health care through mobile applications and smart bands during the treatment process for gastric cancer patients, but the study was insufficient to generalize the number of subjects. Therefore, until now, the results of a multicenter randomized-control study have not been found after long-term application as a supportive tool from immediately after surgery (before treatment) to during the treatment process.
Therefore, in gastric cancer patients who need prognosis management after surgery, we will investigate the effect of mobile application with smart band which has a modular structure reflecting the treatment method and treatment process after surgery.
This study targets patients who underwent gastric cancer surgery, an intervention group (App+IoT device) uses a smart care application tailored to gastric cancer patients created by reflecting the treatment process immediately after surgery and a wearable smart band for 12 months. Control group was 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.

| 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. |

| between baseline (postoperative 2-3days) and postoperative 6 months |
| 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 |
| Self-reported symptom and Quality of life (EORTC-QLQ-STO22) | According to time frame with between-group and within group, trends will be found. EORTC QLQ-STO22 is composed of 5 multi-item scales and 4 single-item measures. For the EORTC QLQSTO22, like symptom scales, a high score represents low QoL. This questionnaire evaluates the effect of chemotherapy, radiation therapy on symptom and quality of life. Therefore, from postoperative 1 month, it will be evaluated. | 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 |
| Visceral fat (㎠) | According to time frame with between-group and within group, trends will be found. Visceral fat at navel level measured by Computed Tomography | Enrollment (postoperative 2-3days), postoperative 6month, 12month |
| Muscle mass (lumbar 2,㎠) | According to time frame with between-group and within group, trends will be found. Muscle mass at lumbar 2 measured by Computed Tomography | Enrollment (postoperative 2-3days), postoperative 6month, 12month |
