Postoperative Prognosis Management Service Based mHealth for Gastric Cancer Patients

Effects of Postoperative Prognosis Management Service Using Mobile Applications and Smart Bands for Gastric Cancer Patients

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.

Inclusion Criteria:

• AJCC stage I-III who has undergone radical gastric cancer surgery (chemotherapy, radiation therapy is irrelevant)
• Patients aged 19 to 75 years old
• Those who can use prognosis management applications and can perform regular follow-up inspections outpatients
• Patients carrying Android or iOS smartphones
• Patients who voluntarily decide to participate and give written consent after hearing detailed explanations about this study

Exclusion Criteria:

• Those who have difficulty using gastric cancer applications (exercise performance, diet management, etc.) due to severe underlying diseases, neuromusculoskeletal diseases, cognitive, and visual impairments
