About this study
Official title: Efficacy of an Agentic AI-based Integrated Digital Healthcare Service for Personalized Prognosis Management in Breast Cancer
As survival rates following breast cancer surgery continue to improve, long-term survivorship management has emerged as a crucial clinical priority. In particular, two major clinical challenges remain: (1) maintaining medication adherence to 5 to 10 years of adjuvant endocrine therapy (tamoxifen or aromatase inhibitors) by actively managing treatment-related adverse symptoms, and (2) early detection and prevention of chronic breast cancer-related lymphedema following axillary lymph node dissection (ALND). Conventional passive monitoring relying on routine outpatient visits every 3 to 6 months often fails to detect daily symptom worsening or subclinical fluid accumulation in a timely manner.
This single-center, prospective, open-label, parallel-group randomized clinical trial evaluates the efficacy of an Agentic AI-based digital healthcare application (Pinkmate; a non-medical mobile health app) and a home bioelectrical impedance analyzer (InBody BWA ON) across two independent cohorts under a single master protocol. This study is conducted at Seoul St. Mary's Hospital and supported by the National IT Industry Promotion Agency (NIPA; Grant No. PJT-25-050007). Dual enrollment is permitted for patients meeting eligibility criteria for both cohorts (total target enrollment: 264 participants).
- Cohort 1: Medication Adherence and Active Symptom Management (N=200) Two hundred breast cancer patients initiating or receiving adjuvant endocrine therapy are randomized 1:1. The experimental arm receives weekly electronic patient-reported outcomes (ePRO), conversational AI chatbot-triggered symptom questionnaires, clinician dashboard alert flags, and proactive telephone calls from clinical staff within 48 hours of an alert. The control arm uses basic medication reminders/checklists and quarterly ePRO collection without proactive alerts. The primary endpoint is the Proportion of Days Covered (PDC) at 6 months.
- Cohort 2: Early Lymphedema Monitoring and Management (N=64) Sixty-four breast cancer patients who underwent ALND (including newly operated patients and prior ALND patients without clinical lymphedema) are randomized 1:1. The experimental arm uses a loaned home InBody BWA ON device at least twice weekly linked to the Pinkmate app; persistent dashboard alerts (3 consecutive days) trigger proactive phone counseling and early clinic visit recommendations. The control arm undergoes routine outpatient surveillance using the in-clinic InBody 770 analyzer and tape measurements, along with educational self-care app content. In both arms, standardized rehabilitation therapy is initiated based on in-clinic InBody 770 and tape circumference measurements using identical criteria. The primary endpoints are the percentage change in affected upper limb volume and the change in affected-arm ECW/TBW ratio from baseline to 6 months post-enrollment.

STUDY DESIGN AND RATIONALE This study is a single-center, prospective, randomized, open-label, parallel-group clinical trial conducted at the Breast Center (Departments of Surgery and Rehabilitation Medicine) of Seoul St. Mary's Hospital, Republic of Korea. The study is supported by the National IT Industry Promotion Agency (NIPA; Grant No. PJT-25-050007) as part of the national Dr. Answer 3.0 digital healthcare project.
Within a single master protocol, two independent clinical research questions are evaluated across two cohorts with independent central computerized 1:1 stratification (stratified by dominant arm concordance with the operated side, radiotherapy status, and body mass index [BMI]):
- Cohort 1: Medication Adherence (N=200; 100 experimental vs 100 control)
- Cohort 2: Lymphedema Prevention (N=64; 32 experimental vs 32 control) Patients who satisfy the eligibility criteria for both Cohort 1 and Cohort 2 may be enrolled simultaneously in both cohorts (Dual Enrollment), resulting in a total target sample size of 264 participants.
STUDY PRODUCTS
- Pinkmate Application (DigitalPharm Co., Ltd.): A closed-access, non-medical health management mobile application (access granted via unique research code and user verification). Features include an Agentic AI chatbot, electronic patient-reported outcomes (ePRO) modules, daily medication checklists, DoingLab Food Camera (AI diet photo calorie analysis), and Bluetooth linkage with the home InBody BWA ON analyzer. All data are managed under AWS cloud security standards (TLS/SSL encryption in transit, AWS KMS encryption at rest, and IAM/MFA access controls).
- InBody BWA ON (InBody Co., Ltd.; MFDS License No. 19-4025): A portable home-use bioelectrical impedance analyzer measuring segmental extracellular water (ECW) and total body water (TBW) to track upper limb fluid changes at home.
- InBody 770 (InBody Co., Ltd.; MFDS License No. 13-1188): An in-clinic multi-frequency bioelectrical impedance analyzer used during scheduled outpatient visits for reference clinical evaluation and paired calibration.
INTERVENTION PROTOCOLS [Cohort 1: Medication Adherence (N=200)]
- Experimental Arm (n=100): Participants complete weekly ePRO surveys via the Pinkmate app. In addition, reporting adverse symptoms (e.g., fatigue, arthralgia) to the conversational Agentic AI chatbot immediately triggers targeted ePRO symptom questionnaires. If symptom severity worsens beyond predefined thresholds compared to prior records, the participant is automatically flagged on the clinician dashboard. Research coordinators and clinical staff monitor the dashboard daily (business days) and conduct proactive telephone consultations within 48 hours of flag detection to provide supportive care, symptom relief education, medication counseling, or expedited clinic referrals.
- Control Arm (n=100): Participants use the Pinkmate app limited to basic medication reminders, daily check-in logs, and quarterly ePRO surveys (every 3 months). Automated AI chatbot symptom triggers, clinician dashboard flagging, and 48-hour proactive telephone interventions are disabled. Symptoms are managed during routine outpatient clinic visits.
[Cohort 2: Lymphedema Monitoring (N=64)] Sixty-four patients who underwent ALND (including newly operated patients and prior ALND patients who currently have no clinical lymphedema) are randomized 1:1.
- Experimental Arm (n=32): Participants receive a loaned home InBody BWA ON device (loaned until December 31, 2028) and perform self-measurements at home at least twice weekly (daily recommended; on waking, post-voiding, identical clothing). Data are transmitted via Bluetooth to the clinician dashboard. Based on bioimpedance principles, dashboard alert flags are triggered when: (1) affected-arm ECW/TBW ratio increases by >= 0.010 from baseline, or (2) interlimb (affected/unaffected) ECW/TBW ratio reaches >= 1.020. When an alert persists for 3 consecutive days upon daily dashboard review, medical staff contact the patient by telephone within 48 hours to recommend intensive self-care (lymphatic drainage exercises) and an early outpatient visit.
- Control Arm (n=32): Participants do not receive the home BWA ON device and undergo bioimpedance (InBody 770) and tape circumference measurements only at scheduled outpatient visits. App-based educational contents and scheduled PRO assessments are provided without continuous home bioimpedance linkage or dashboard alerts.
- Standardized Clinical Rehabilitation Protocol (Common to Both Arms in Cohort 2):
Official clinical diagnosis and initiation of rehabilitation therapy are determined identically in both groups based on in-clinic InBody 770 and tape circumference measurements:
- Subclinical Lymphedema: Defined as a 5% to <10% limb volume increase from baseline (tape measure) OR an increase in affected-arm ECW/TBW ratio >= 0.010 from baseline (InBody 770). Managed with Class 2 compression sleeve and gauntlet for >= 12 hours/day for 4 weeks.
- Clinical Lymphedema: Defined as >= 10% limb volume increase from baseline (tape measure) OR affected-arm ECW/TBW ratio >= 0.395 (InBody 770). Managed with standardized rehabilitation therapy according to ISL stage (manual lymphatic drainage twice weekly, therapeutic exercises, compression garments/bandaging).
SAMPLE SIZE JUSTIFICATION AND STATISTICAL PLAN
- Cohort 1: Assuming a 6-month mean PDC of 0.70 (SD 0.20) in the control group and 0.80 (SD 0.20) in the experimental group (effect size d = 0.50), 64 patients per arm are required for 80% power at a two-sided alpha of 0.05. Accounting for a ~20% dropout rate and annual surgical volume, 100 patients per arm (total N=200) will be enrolled.
- Cohort 2: Assuming a 6-month mean increase in affected-arm ECW/TBW ratio of 0.010 (SD 0.012) in the control group versus 0.002 (SD 0.010) in the experimental group (effect size d = 0.72), 26 patients per arm are required for 80% power at a two-sided alpha of 0.05. Allowing for a 20% dropout rate, 32 patients per arm (total N=64) will be enrolled.
- Primary analyses will be conducted on the Intention-to-Treat (ITT) population, with missing data handled by multiple imputation. An interim analysis for project KPI reporting is planned at 6 months after completion of enrollment or December 31, 2028; follow-up continues up to 60 months (until December 31, 2031).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Cohort1: Pinkmate Agentic AI-ePRO Active Management PlatformBehavioural
Also called Pinkmate App
Closed-access mobile health application (Pinkmate) featuring an Agentic AI conversational chatbot and electronic patient-reported outcomes (ePRO) module. Participants complete weekly ePRO symptom surveys. In addition, adverse symptom complaints during chatbot interactions automatically trigger targeted in-depth ePRO questionnaires. Worsening symptoms beyond predefined thresholds generate alert flags on the clinician web dashboard. Clinical staff monitor the dashboard daily (business days) and conduct proactive telephone consultations within 48 hours of an alert to provide supportive care, symptom relief education, medication counseling, or expedited clinic referrals.
Cohort1: Pinkmate Basic Medication Reminders and Standard Outpatient CareOther
Also called Standard care with basic Pinkmate app
Participants utilize the Pinkmate mobile application with functionality limited to basic medication reminders, daily adherence check-ins, and quarterly (every 3 months) ePRO questionnaires aligned with scheduled outpatient clinic visits. Automated conversational AI chatbot symptom triggers, clinician dashboard alert flags, and proactive 48-hour telephone consultations are disabled. Adverse symptom evaluation, medication counseling, and management are conducted during routine in-person outpatient clinic visits according to standard clinical practice.
Cohort2: InBody BWA ON Home Bioimpedance Monitoring and Behavioral AppDevice
Also called InBody BWA ON (MFDS License No. 19-4025)
Participants receive a loaned portable multi-frequency bioelectrical impedance analyzer (InBody BWA ON; MFDS License No. 19-4025; loaned until December 31, 2028). Patients perform self-measurements at home under standardized morning post-voiding conditions at least twice weekly (daily recommended). Data are transmitted via Bluetooth to the Pinkmate app and clinician dashboard. Persistent bioimpedance alerts (affected-arm ΔECW/TBW ratio ≥ 0.010 from baseline or interlimb ratio ≥ 1.020 for 3 consecutive days) trigger medical staff telephone counseling within 48 hours for self-care reinforcement and early clinic visits. Participants also utilize app-based AI lifestyle coaching and arm fluid tracking graphs. In-clinic InBody 770 measurements are performed at routine visits.
Cohort2: Routine In-Clinic InBody 770 Monitoring and Educational AppOther
Also called Standard surveillance with InBody 770 (MFDS No. 13-1188)
Participants do not receive the home InBody BWA ON device and use the Pinkmate mobile application solely for educational self-care content and scheduled surveys. Continuous home bioimpedance data linkage and real-time dashboard alert flagging are disabled. Arm swelling and segmental bioimpedance are evaluated exclusively during routine outpatient visits (at 3, 6, 12, 24, 36, and 60 months) using the in-clinic InBody 770 analyzer (MFDS License No. 13-1188) and circumference tape measurements. Standardized rehabilitation therapy upon meeting predefined criteria for subclinical or clinical lymphedema is administered identically to the experimental arm.

What is being measured
The primary outcome is the main question the study is designed to answer.
Cohort1: Proportion of Days Covered (PDC) for Adjuvant Endocrine Therapy
PDC is defined as the percentage of days during the evaluation period that the participant actually took prescribed adjuvant endocrine therapy (tamoxifen or aromatase inhibitors). It is calculated from prescription records and daily in-app medication check logs: PDC = (Number of days medication taken / Total observation days) × 100. Mean PDC and the proportion of participants achieving PDC ≥ 80% are compared between arms.
Measured: At 6 months after intervention initiation
Cohort2: Percentage Change from Baseline in Affected Upper Limb Volume
Limb volume is derived from bilateral upper limb circumferences measured every 4 cm starting 2 cm below the axilla down to the wrist using a standardized tape measure (mean of two measurements). Volume is calculated using the truncated cone formula. The relative percentage change in affected upper limb volume from baseline to 6 months post-enrollment is compared between arms.
Measured: Baseline (enrollment) and 6 months after enrollment
Cohort2: Change from Baseline in Affected Upper Limb ECW/TBW Ratio
Segmental extracellular water-to-total body water ratio (ECW/TBW) of the affected upper limb is measured using the in-clinic multi-frequency bioelectrical impedance analyzer (InBody 770). The change in affected-arm ECW/TBW ratio from baseline to 6 months post-enrollment (ΔECW/TBW) is compared between arms.
Measured: Baseline (enrollment) and 6 months after enrollment
Secondary outcomes (6)
Cohort1: Long-Term Proportion of Days Covered (PDC) for Adjuvant Endocrine Therapy
PDC is calculated as the percentage of days covered by prescribed adjuvant endocrine therapy at each follow-up time point, analyzed over time across arms using a linear mixed model (LMM).
Measured: At 12, 24, 36, and 60 months after intervention initiation
Cohort1: Change from Baseline in Functional Assessment of Cancer Therapy - Breast (FACT-B) Score
Quality of life is assessed using the Korean version of FACT-B (Version 4). Total score ranges from 0 to 148, with higher scores reflecting better breast cancer-specific health-related quality of life.
Measured: Baseline, and at 3, 6, 12, 24, 36, and 60 months
Cohort1: Change from Baseline in Endocrine Therapy-Related Symptom PRO T-scores
Standardized ePRO symptom T-scores for key endocrine therapy-associated adverse symptoms (including fatigue and arthralgia) collected via the mobile application.
Measured: Baseline, and at 3, 6, 12, 24, 36, and 60 months
Cohort2: Cumulative Incidence of Subclinical and Clinical Upper Limb Lymphedema
Proportion of participants developing subclinical lymphedema (affected-arm volume increase ≥ 5% to < 10% or InBody 770 ΔECW/TBW ≥ 0.010) or clinical lymphedema (affected-arm volume increase ≥ 10% or InBody 770 ECW/TBW ≥ 0.395).
Measured: At 6, 12, 24, 36, and 60 months after enrollment
Cohort2: Progression of International Society of Lymphology (ISL) Lymphedema Stage
Proportion of participants experiencing progression from ISL Stage 1 to Stage 2 or higher based on clinical evaluation by a rehabilitation medicine specialist.
Measured: Baseline, and at 6, 12, 24, 36, and 60 months after enrollment
Both Cohorts: System Usability Scale (SUS) Score for Pinkmate Mobile Application
Patient-evaluated usability of the Pinkmate mobile health application using the System Usability Scale (SUS). Total score ranges from 0 to 100, where higher scores indicate greater usability and satisfaction.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
As survival rates following breast cancer surgery continue to improve, long-term survivorship management has emerged as a crucial clinical priority. In particular, two major clinical challenges remain: (1) maintaining medication adherence to 5 to 10 years of adjuvant endocrine therapy (tamoxifen or aromatase inhibitors) by actively managing treatment-related adverse symptoms, and (2) early detection and prevention of chronic breast cancer-related lymphedema following axillary lymph node dissection (ALND). Conventional passive monitoring relying on routine outpatient visits every 3 to 6 months often fails to detect daily symptom worsening or subclinical fluid accumulation in a timely manner.
This single-center, prospective, open-label, parallel-group randomized clinical trial evaluates the efficacy of an Agentic AI-based digital healthcare application (Pinkmate; a non-medical mobile health app) and a home bioelectrical impedance analyzer (InBody BWA ON) across two independent cohorts under a single master protocol. This study is conducted at Seoul St. Mary's Hospital and supported by the National IT Industry Promotion Agency (NIPA; Grant No. PJT-25-050007). Dual enrollment is permitted for patients meeting eligibility criteria for both cohorts (total target enrollment: 264 participants).
- Cohort 1: Medication Adherence and Active Symptom Management (N=200) Two hundred breast cancer patients initiating or receiving adjuvant endocrine therapy are randomized 1:1. The experimental arm receives weekly electronic patient-reported outcomes (ePRO), conversational AI chatbot-triggered symptom questionnaires, clinician dashboard alert flags, and proactive telephone calls from clinical staff within 48 hours of an alert. The control arm uses basic medication reminders/checklists and quarterly ePRO collection without proactive alerts. The primary endpoint is the Proportion of Days Covered (PDC) at 6 months.
- Cohort 2: Early Lymphedema Monitoring and Management (N=64) Sixty-four breast cancer patients who underwent ALND (including newly operated patients and prior ALND patients without clinical lymphedema) are randomized 1:1. The experimental arm uses a loaned home InBody BWA ON device at least twice weekly linked to the Pinkmate app; persistent dashboard alerts (3 consecutive days) trigger proactive phone counseling and early clinic visit recommendations. The control arm undergoes routine outpatient surveillance using the in-clinic InBody 770 analyzer and tape measurements, along with educational self-care app content. In both arms, standardized rehabilitation therapy is initiated based on in-clinic InBody 770 and tape circumference measurements using identical criteria. The primary endpoints are the percentage change in affected upper limb volume and the change in affected-arm ECW/TBW ratio from baseline to 6 months post-enrollment.

Within a single master protocol, two independent clinical research questions are evaluated across two cohorts with independent central computerized 1:1 stratification (stratified by dominant arm concordance with the operated side, radiotherapy status, and body mass index [BMI]):
- Cohort 1: Medication Adherence (N=200; 100 experimental vs 100 control)
- Cohort 2: Lymphedema Prevention (N=64; 32 experimental vs 32 control) Patients who satisfy the eligibility criteria for both Cohort 1 and Cohort 2 may be enrolled simultaneously in both cohorts (Dual Enrollment), resulting in a total target sample size of 264 participants.
STUDY PRODUCTS
- Pinkmate Application (DigitalPharm Co., Ltd.): A closed-access, non-medical health management mobile application (access granted via unique research code and user verification). Features include an Agentic AI chatbot, electronic patient-reported outcomes (ePRO) modules, daily medication checklists, DoingLab Food Camera (AI diet photo calorie analysis), and Bluetooth linkage with the home InBody BWA ON analyzer. All data are managed under AWS cloud security standards (TLS/SSL encryption in transit, AWS KMS encryption at rest, and IAM/MFA access controls).
- InBody BWA ON (InBody Co., Ltd.; MFDS License No. 19-4025): A portable home-use bioelectrical impedance analyzer measuring segmental extracellular water (ECW) and total body water (TBW) to track upper limb fluid changes at home.
- InBody 770 (InBody Co., Ltd.; MFDS License No. 13-1188): An in-clinic multi-frequency bioelectrical impedance analyzer used during scheduled outpatient visits for reference clinical evaluation and paired calibration.
INTERVENTION PROTOCOLS [Cohort 1: Medication Adherence (N=200)]
- Experimental Arm (n=100): Participants complete weekly ePRO surveys via the Pinkmate app. In addition, reporting adverse symptoms (e.g., fatigue, arthralgia) to the conversational Agentic AI chatbot immediately triggers targeted ePRO symptom questionnaires. If symptom severity worsens beyond predefined thresholds compared to prior records, the participant is automatically flagged on the clinician dashboard. Research coordinators and clinical staff monitor the dashboard daily (business days) and conduct proactive telephone consultations within 48 hours of flag detection to provide supportive care, symptom relief education, medication counseling, or expedited clinic referrals.
- Control Arm (n=100): Participants use the Pinkmate app limited to basic medication reminders, daily check-in logs, and quarterly ePRO surveys (every 3 months). Automated AI chatbot symptom triggers, clinician dashboard flagging, and 48-hour proactive telephone interventions are disabled. Symptoms are managed during routine outpatient clinic visits.
[Cohort 2: Lymphedema Monitoring (N=64)] Sixty-four patients who underwent ALND (including newly operated patients and prior ALND patients who currently have no clinical lymphedema) are randomized 1:1.
- Experimental Arm (n=32): Participants receive a loaned home InBody BWA ON device (loaned until December 31, 2028) and perform self-measurements at home at least twice weekly (daily recommended; on waking, post-voiding, identical clothing). Data are transmitted via Bluetooth to the clinician dashboard. Based on bioimpedance principles, dashboard alert flags are triggered when: (1) affected-arm ECW/TBW ratio increases by >= 0.010 from baseline, or (2) interlimb (affected/unaffected) ECW/TBW ratio reaches >= 1.020. When an alert persists for 3 consecutive days upon daily dashboard review, medical staff contact the patient by telephone within 48 hours to recommend intensive self-care (lymphatic drainage exercises) and an early outpatient visit.
- Control Arm (n=32): Participants do not receive the home BWA ON device and undergo bioimpedance (InBody 770) and tape circumference measurements only at scheduled outpatient visits. App-based educational contents and scheduled PRO assessments are provided without continuous home bioimpedance linkage or dashboard alerts.
- Standardized Clinical Rehabilitation Protocol (Common to Both Arms in Cohort 2):
Official clinical diagnosis and initiation of rehabilitation therapy are determined identically in both groups based on in-clinic InBody 770 and tape circumference measurements:
- Subclinical Lymphedema: Defined as a 5% to <10% limb volume increase from baseline (tape measure) OR an increase in affected-arm ECW/TBW ratio >= 0.010 from baseline (InBody 770). Managed with Class 2 compression sleeve and gauntlet for >= 12 hours/day for 4 weeks.
- Clinical Lymphedema: Defined as >= 10% limb volume increase from baseline (tape measure) OR affected-arm ECW/TBW ratio >= 0.395 (InBody 770). Managed with standardized rehabilitation therapy according to ISL stage (manual lymphatic drainage twice weekly, therapeutic exercises, compression garments/bandaging).
SAMPLE SIZE JUSTIFICATION AND STATISTICAL PLAN
- Cohort 1: Assuming a 6-month mean PDC of 0.70 (SD 0.20) in the control group and 0.80 (SD 0.20) in the experimental group (effect size d = 0.50), 64 patients per arm are required for 80% power at a two-sided alpha of 0.05. Accounting for a ~20% dropout rate and annual surgical volume, 100 patients per arm (total N=200) will be enrolled.
- Cohort 2: Assuming a 6-month mean increase in affected-arm ECW/TBW ratio of 0.010 (SD 0.012) in the control group versus 0.002 (SD 0.010) in the experimental group (effect size d = 0.72), 26 patients per arm are required for 80% power at a two-sided alpha of 0.05. Allowing for a 20% dropout rate, 32 patients per arm (total N=64) will be enrolled.
- Primary analyses will be conducted on the Intention-to-Treat (ITT) population, with missing data handled by multiple imputation. An interim analysis for project KPI reporting is planned at 6 months after completion of enrollment or December 31, 2028; follow-up continues up to 60 months (until December 31, 2031).

Total target enrollment is 264 participants.
| Arm | Type | Receives |
|---|---|---|
| Cohort 1 Experimental: Active AI and ePRO Platform | Experimental | Behavioral: Cohort1: Pinkmate Agentic AI-ePRO Active Management PlatformParticipants receive the Pinkmate mobile app with active electronic patient-reported outcomes (ePRO) and Agentic AI monitoring. Patients complete weekly ePRO questionnaires. In addition, reporting adverse symptoms (e.g., fatigue, arthralgia) to the conversational AI chatbot immediately triggers targeted in-depth ePRO assessments. When symptom scores worsen beyond predefined thresholds, the patient is automatically flagged on the clinician dashboard. Clinical staff review the dashboard daily (business days) and conduct proactive telephone consultations within 48 hours to provide supportive care, symptom relief education, medication adherence counseling, and expedited clinic referrals. |
| Cohort 1 Control: Standard Care with Basic App | Active comparator | Other: Cohort1: Pinkmate Basic Medication Reminders and Standard Outpatient CareParticipants use the Pinkmate mobile app limited to basic medication reminders, daily check-in logs, and quarterly ePRO surveys (every 3 months) aligned with routine outpatient visit schedules. Conversational AI chatbot-triggered questionnaires, automated clinician dashboard alert flagging, and proactive 48-hour telephone intervention by medical staff are disabled. Symptoms and medication adherence are managed during routine in-person outpatient clinic visits according to standard care. |
| Cohort 2 Experimental: Home BWA ON Monitoring + AI App | Experimental | Device: Cohort2: InBody BWA ON Home Bioimpedance Monitoring and Behavioral AppBreast cancer patients who underwent ALND (including newly operated patients and prior ALND patients without clinical lymphedema) are loaned a home bioimpedance analyzer (InBody BWA ON, loaned until Dec 31, 2028). Patients perform self-measurements at home at least twice weekly (daily recommended; on waking, post-voiding) linked to the Pinkmate app. Persistent dashboard alerts (affected-arm ΔECW/TBW ≥ 0.010 or interlimb ratio ≥ 1.020 for 3 days) trigger clinical staff phone calls within 48 hours for self-care reinforcement and early clinic visits. Participants also utilize app-based AI lifestyle coaching and fluid tracking graphs. In-clinic InBody 770 and circumference tape measurements are performed at routine visits. |
| Cohort 2 Control: Routine In-Clinic InBody 770 Monitoring | Active comparator | Other: Cohort2: Routine In-Clinic InBody 770 Monitoring and Educational AppBreast cancer patients who underwent ALND do not receive the home InBody BWA ON device and use the Pinkmate app solely for educational self-care content and scheduled surveys. Continuous home bioimpedance data linkage and real-time dashboard alerts are disabled. Limb volume and bioimpedance are evaluated exclusively during scheduled outpatient visits using in-clinic InBody 770 and circumference tape measurements. Standardized rehabilitation therapy upon meeting criteria for subclinical or clinical lymphedema is administered identically to the experimental arm. |

Primary outcome
Cohort1: Proportion of Days Covered (PDC) for Adjuvant Endocrine Therapy
Time frame: At 6 months after intervention initiation
PDC is defined as the percentage of days during the evaluation period that the participant actually took prescribed adjuvant endocrine therapy (tamoxifen or aromatase inhibitors). It is calculated from prescription records and daily in-app medication check logs: PDC = (Number of days medication taken / Total observation days) × 100. Mean PDC and the proportion of participants achieving PDC ≥ 80% are compared between arms.
Cohort2: Percentage Change from Baseline in Affected Upper Limb Volume
Time frame: Baseline (enrollment) and 6 months after enrollment
Limb volume is derived from bilateral upper limb circumferences measured every 4 cm starting 2 cm below the axilla down to the wrist using a standardized tape measure (mean of two measurements). Volume is calculated using the truncated cone formula. The relative percentage change in affected upper limb volume from baseline to 6 months post-enrollment is compared between arms.
Cohort2: Change from Baseline in Affected Upper Limb ECW/TBW Ratio
Time frame: Baseline (enrollment) and 6 months after enrollment
Segmental extracellular water-to-total body water ratio (ECW/TBW) of the affected upper limb is measured using the in-clinic multi-frequency bioelectrical impedance analyzer (InBody 770). The change in affected-arm ECW/TBW ratio from baseline to 6 months post-enrollment (ΔECW/TBW) is compared between arms.
