The goal of this multicentric randomized controlled clinical trial is to test the role of mobile medical application (APP) on adjuvant therapy compliance and quality of life (QoL) in patients with early breast cancer. Participants assigned to the Ruijin Breast Cancer APP (RJBC-APP) group can receive treatment reminders, matters needing attention as well as science knowledge and they can communicate with the medical staff during adjuvant treatments while follow-up can only be conducted in outpatient clinic for those in the Control group.
Adjuvant treatments has significantly improved the prognosis of early breast cancer patients. However, previous studies suggested the existence of noncompliance to adjuvant therapies, which might cause detriments to disease outcomes. The goal of this multicentric randomized controlled clinical trial is to test the role of mobile medical application (APP) on adjuvant therapy compliance and quality of life (QoL) in patients with early breast cancer. Patients diagnosed with invasive breast cancers after surgery will be randomly assigned to the Ruijin Breast Cancer APP (RJBC-APP) group or the Control group. Those in the RJBC-APP group can receive treatment reminders, matters needing attention as well as science knowledge and they can communicate with the medical staff during adjuvant treatments while follow-up can only be conducted in outpatient clinic for those in the Control group. The primary endpoint is the rate of adjuvant therapy compliance at 12 months after randomization. Secondary endpoints consist of compliance rates at 3, 6, 24 months after randomization, QoL and cancer-related symptoms scores at 3, 6, 12, 24 months, disease-free survival (DFS) and overall survival (OS) at 60 months.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| The RJBC-APP group | Experimental | Participants randomized to the RJBC-APP group should register on the RJBC-APP, through which they can receive treatment reminders, matters needing attention as well as science knowledge and communicate with the medical staff. |
|
| The Control group | Active Comparator | Participants randomized to the Control group have no access to the RJBC-APP and post-surgical follow-up can only be conducted in outpatient clinic. |

| The RJBC-APP | Device | The RJBC-APP consists of the following features: 1. Login, logout, setting, and modification of personal information. 2. Full-course management included registering for information on the surgical treatment, viewing the results of the multidisciplinary team (MDT) discussion, generating the treatment process according to the MDT discussion, receiving the reminder of the treatment, confirming the completion of the treatment, filling in the follow-up information, and consulting a specialist nurse. 3. Questionnaire and feedback. |
| Measure | Description | Time Frame |
|---|---|---|
| Rate of compliance with adjuvant therapy | Compliance is defined as completing the adjuvant therapy recommended by multidisciplinary team in terms of the type, dosage, date and course, and non-compliance is considered in the presence of any of the following cases: 1) the patient refuses to accept the recommended treatments, 2) the actual treatments are different from those recommended, 3) the patient dose not complete the full course of treatments, 4) the patient starts the treatment 7 days or more later than the established date, 5) the patient does not follow the recommended dose and intensity. | 12 months after adjuvant therapy |
| Overall Survival (OS) | OS is calculated from the date of surgery to the date of death. | 60 months after adjuvant therapy |

| Quality of Life (QoL) Scale | The QoL Scale is evaluated by the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30, version 3.0). The questionnaire is composed of 30 items among which items 1-28 are divided into 4 levels (scored as 1-4 respectively, higher scores mean a worse outcome) and items 29-30 are divided into 7 grades (scored as 1-7 respectively, higher scores mean a better score). The items are further divided into 15 domains. The standard score (0-100) is calculated from raw score of each domain and higher scores mean a better outcome. | 3、6、12 and 24 months after adjuvant therapy |
| Cancer-related symptoms scores | Cancer-related symptoms are evaluated by the MD Anderson Symptom Inventory (MDASI). The questionnaire is composed of 19 items among which items 1-13 are degree of 13 common symptoms and items 14-19 are degrees of the impact on daily life (scored as 1-10 respectively, higher scores mean a better score). The total score (0-190) is calculated by sum of each item and higher scores mean a worse outcome. | 3、6、12 and 24 months after adjuvant therapy |
| Disease-free Survival (DFS) | DFS is calculated from the date of surgery to the first date of the following events: local recurrence, regional recurrence, distant metastasis, contralateral breast cancer, secondary primary malignancy and death. | 60 months after adjuvant therapy |
