Continuous Positive Airway Pressure (CPAP) Assisted Radiotherapy in Breast Cancer
Recruiting now · Phase 2/Phase 3
Conditions studied: Breast Cancer Early Stage Breast Cancer (Stage 1-3)
In brief
This study is a prospective, non-randomized clinical study aimed at investigating the potential benefits of continuous positive airway pressure (CPAP) support during radiotherapy for breast cancer. CPAP is a device commonly used to support breathing, for example in patients with sleep apnea. The investigators expect a reduction in radiation doses to the heart and/or lungs with CPAP-supported radiotherapy compared to standard radiotherapy (without CPAP), which may also lead to a decrease in radiation-induced heart and/or lung conditions in the long term. The study will also examine how the use of a CPAP device can be implemented in daily radiotherapy practice.

Who can join
Age: 40 and older, up to 80. Sex: female. Healthy volunteers: not accepted.
You may qualify if…
- Voluntary written informed consent of the participant or their legally authorized representative has been obtained prior to any screening procedures
- At least 40 years of age and 80 years or younger at the time of signing the Informed Consent Form (ICF)
- Female patients
- Patients that underwent breast conserving surgery (BCS)
- Left-sided invasive BC / in situ carcinoma with indication for adjuvant RT (<70 years old)
- Left-sided invasive BC with indication for adjuvant locoregional RT (including RT of the regional lymph nodes) (70-80 years old)
- Right-sided invasive BC with indication for adjuvant locoregional RT (including RT of the regional lymph nodes)
- Prior chemotherapy allowed
- Prior immunotherapy allowed
- Prior / concomitant hormonal therapy allowed
- Prior / concomitant HER2-targeted therapy allowed
You may not qualify if…
- Patient has active bullous lung disease, bypassed upper airway, pneumothorax, cerebral spinal fluid leaks, abnormalities of the cribriform plate (contra-indications for the use of CPAP)
- Patient has history of major head trauma and/or pneumocephalus (contra-indications for the use of CPAP)
- Any disorder, which in the investigator's opinion might jeopardise participant's safety or compliance with the CIP.
- Female who is pregnant, breast-feeding or intends to become pregnant (which is a contra-indication for RT in general)
- Male BC patients
- Patients that underwent mastectomy Patients whose initial tumor was located just beneath the skin (defined as being less than 28mm below the breast surface), indicating the need for an electron boost
- Patients requiring RT boost on positive lymph nodes
- Distant metastasis
- Breast implants in situ
- Right-sided in situ carcinoma
- Right-sided invasive BC only requiring local adjuvant RT (without irradiation of the regional lymph nodes, because the presumed benefit on cardiac doses of local right-sided breast irradiation is assumed to be rather small because of the left anatomical position of the heart)
- Bilateral BC
- Concomitant use of chemotherapy during RT
- Substantial comorbidities, incompatible with RT or CPAP use, estimated by the treating radiation oncologist
- Insufficient arm mobility to perform comfortable arm positioning in radiation treatment position, evaluated by the treating radiation oncologist
- Other active oncological disease / treatment with the exception of non-melanoma skin cancer
- Previous RT with overlapping RT fields with actual target volume
