Breast Cancer, Breast Cancer Survivorship, Digital Health
Conditions
Brief summary
The ultimate goal of this research and development is to develop personalized digital healthcare technologies and self-management strategies based on self-assessment results and evidence, for breast cancer survivors who require management and recovery from acute and chronic side effects related to various treatments (surgery, chemotherapy, radiation, hormone therapy, etc.). Additionally, the aim is to verify the clinical applicability and establish a service model to address the diverse unmet healthcare needs of breast cancer survivors.
Interventions
DEVICEdigital health (application and smartwatch)
The application allows users to conduct self-assessments for managing symptoms and side effects related to treatment. Based on the assessment results, it provides personalized self-management strategies. Additionally, users can access features for exercise, diet, and weight management.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| PROMIS29 | Baseline, Month 1, Month 3, Month 6 | Full Title: Patient-Reported Outcomes Measurement Information System Objective: health related quality of life Scoring System: Each item is rated on a scale of 1 to 5. Lower scores indicate better health for pain, depression, anxiety, and fatigue, while higher scores indicate better health for physical function, social roles, and activities, and sleep disorders. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| EQ-5D-5L | Baseline, Month 1, Month 3, Month 6 | Full Title: EuroQol 5-Dimension 5-level Objective: quality of life Scoring System: Each item is evaluated on a 5-point scale and weighted according to the country. EQ VAS evaluates data on a scale of 0-100, with a higher score indicating better health. |
| PRO-CTCAE | Month 1, Month 3, Month 6 | Full Title: Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events Objective: Clinical symptoms and adverse effects reported by patients Scoring System: Evaluate the frequency, severity, interference with daily activities, amount, and presence/absence of side effects over the past 7 days. |
| ICF (International Classification of Functioning, Disability, and Health) | Baseline, Month 1, Month 3, Month 6 | Full Title: International Classification of Functioning, Disability and Health Objective: function, activity and participant, environment Scoring System: A. Assess the 8 items of body functions, 8 items of activities and participation, and 8 items of environmental factors of the breast cancer ICF core set brief B. Body functions are assessed as 0 (no problems) - 4 (extreme problems), 9 (not applicable). Activities and participation are assessed as 0 (no difficulties) - 4 (extreme difficulties), 9 (not applicable). Environment is assessed as 0 (no barriers) - 4 (extreme barriers), +0 (no facilitating factors) - +4 (complete facilitating factors), 9 (not applicable). |
| Activity (step count) | Baseline, Month 1, Month 3, Month 6 | Objective: Number of steps taken in the past month Scoring System: Number of steps measured by mobile phone |
| CBI-K | Baseline, Month 3, Month 6 | Full Title: Cancer Behavior Inventory version 3.0 - Korea Objective: Measuring self-efficacy for coping behaviors that can be taken during cancer treatment Scoring System: A. Consists of 7 subscales (27 items): Maintaining activity and independence (4 items), Seeking and understanding medical information (4 items), Managing stress and pain (4 items), Managing side effects (4 items), Accepting cancer/maintaining a positive attitude (4 items), Finding social support (3 items), Using spiritual coping methods (4 items) B. Rating on a 7-point scale. A higher score indicates a higher self-efficacy for overcoming cancer. |
