This study aims to develop and examine the feasibility and preliminary effectiveness of an AI-based sarcoma chatbot building on ChatGPT (ASCC) to address the information needs of sarcoma patients. We hypothesized: 1) the ASCC will demonstrate good usability; 2) the study will be feasible in terms of all feasibility indicators; 3) the experimental group will report improved satisfaction and self-efficacy, decreased anxiety and stress than the control groups upon completion of the intervention. The ASCC will be developed using a co-design approach. A pilot randomized controlled trial will then be conducted in the three oncology wards of collaborative hospitals. Seventy-eight sarcoma patients will be recruited and randomized to the experimental group (n=39) and the control group (n=39). The experimental group will use the ASCC available 24/7 via voice or text for disease-related questions for one month while the control group will receive usual care.

|---|---|---|---|
| ASCC | Experimental | An AI-based sarcoma chatbot building on ChatGPT (ASCC) using a co-design approach. |
|
| Control | Other | The standard information from doctor-patient consultations and hospital |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| ASCC (sarcoma-specific AI chatbot) | Other | The participants in the experimental group will access the ASCC via a webpage alongside standard information from health professionals for one month (15 minutes weekly). |
| Measure | Description | Time Frame |
|---|---|---|
| Screening rate | Calculated by dividing the number of sarcoma patients screened by the research team by the number of sarcoma patients. | During the enrollment period of this project. |
| Eligibility rate | Calculated by dividing the number of participants who are eligible by the number who are screened. | During the enrollment period of this project. |
| Consent rate | Calculated by dividing the number of participants who were randomized into intervention and control groups by those provide consent. | During the enrollment period of this project. |
| Randomization rate | Calculated by dividing the number of participants who consent to join the study by the number who are eligible. | During the enrollment period of this project. |
| Attendance rate | Calculated by dividing the number of participants who complete the intervention by those who are randomised | Baseline and immediately after intervention (T1) |
| Retention rate | Calculated by dividing the number of participants who remain in the study by those who are randomized. This will be calculated by groups. | Baseline and immediately after intervention (T1) |
| Completion rate | Calculated by dividing the number of participants who returned questionnaires by the number of questionnaires distributed. Calculated by dividing the number of participants who remain in the study by those who are randomized. This will be calculated by groups. |
| Measure | Description | Time Frame |
|---|---|---|
| Information satisfaction | The EORTC QLQ-INFO25 will be used to evaluate participants' satisfaction with the information received. A four-point Likert scale is used to score 25 items ('nothing' = 1 to 'a lot' = 4), with higher scores indicating greater information satisfaction. | Baseline and immediately after intervention (T1) |

| Routine Clinical Care | Other | Participants in the control group will receive routine clinical care, including standard information from doctor-patient consultations (e.g., diagnosis, treatment, medical tests) and hospital provided sarcoma and treatment leaflet. |
|
| Baseline and immediately after intervention (T1) |
| Proportion of missing data | Calculated as the percentage of missing values in the dataset. Unknown or blank values will be considered missing values. | Baseline and immediately after intervention (T1) |
| Adverse events | Adverse events are defined as unfavourable and unintended events that are not present, or appear to have worsened during the study. | immediately after intervention (T1) |
| Anxiety and stress |
The Depression Anxiety Stress Scale-21 (DASS-21) will be used to assess anxiety and stress.(36) 21 items are scored using a four-point Likert scale, with higher score indicating more severe symptoms. |
| Baseline and immediately after intervention (T1) |
| Self-efficacy | Self-efficacy will be assessed using the Strategies Used by People to Promote Health (SUPPH) with good reliability and validity. This 28-item likert scale measure self-care self-efficacy, with higher scores indicating more positive perceptions of self-efficacy. | Baseline and immediately after intervention (T1) |
| System Usability Scale | System Usability Scale (SUS) will be used to measure the usability of digital health solutions by 10 items rated on a 5-point Likert scale from 0-100. The chatbot will be considered highly usable if the mean score exceeds 68. | immediately after intervention (T1) |
