研究概览
简要总结
The goal of this clinical trial is to find out whether using a personalized breast holder (called VENUS SHELL™) can improve positioning and patient comfort during prone radiotherapy (radiotherapy given while the patient lies on her stomach).
The main goals of the study are:
- To confirm that using the VENUS SHELL™ is safe and effective
- To assess whether the VENUS SHELL™ helps deliver accurate radiation treatment in a faster and more comfortable way
Participants will:
- Attend a study visit before radiotherapy to have a breast surface scan (no radiation) and enable the production of their personalized VENUS SHELL™
- Use their VENUS SHELL™ during radiotherapy planning and treatment
- Be asked to complete questionnaires about their comfort

- •Pregnancy or breast feeding
- •Claustrophobia
- •Patient with a body weight exceeding 120 kg
- •Patient with pendulous breasts that come into contact with the CT table, preventing adequate space for shell usage

结局指标
主要结局
Feasibility outcome: Time (days) between surface scan data received by HeroSupport and arrival of the VENUS SHELL™ at the clinical site
时间窗: Treatment set-up (up to 21 days)
Performance outcomes: radiotherapy delivered within 15 minutes timeslot and patient positioning accuracy within 2 mm
时间窗: Study treatment (10 days)
Radiotherapy time includes patient positioning and treatment. Patient positioning accuracy is measured though displacement via Tattoos and Image-Guided Radiation Therapy imaging
Safety outcome: number of medical device-related Adverse Events as assessed by CTCAE v5.0
时间窗: Through study completion (an average of 3 months)
次要结局
- Patients' comfort (questionnaires)(Treatment set-up (up to 21 days) and study treatment (10 days))
- Evaluate ease of use and overall satisfaction of using the VENUS SHELL (questionnaires)(Study treatment (10 days))
- In-vivo dosimetry measured with thermoluminescent dosimeters (TLDs)(Radiotherapy treatment first session, up to last session (10 days))
