prioritization [4]. PRISMA methodology was applied to document the selection and ensure transparency (Figure 1). Studies addressing VBHC implementation across specialties and settings were included to identify transferable factors relevant to oncology networks. Data extraction followed a structured protocol, and findings were synthesized through thematic analysis.

During breast radiotherapy, new planning is essential for tissue swelling of 5 mm or more due to significant underdosing. Shrinking results in moderate overdosing and an increased surface dose. This retrospective study analyzed the necessity for contouring revision of target volumes because of different degrees and temporal resolution of breast edema in relation to intervals between surgery, CT simulation, and radiation therapy initiation in patients
Results: From an initial pool of 57.373 records, 260 studies met the inclusion criteria. Thematic analysis revealed three domains influencing VBHC implementation: contextual factors, stakeholder dynamics, and governance structures. These themes included factors such as (inter)organizational culture, leadership, and financing. A recurring theme was the variation in how “value” is defined—ranging from clinical outcomes and cost- effectiveness to patient experience and equity. These differing interpretations influence strategic priorities and may lead to misalignment between stakeholders. Conclusion: This review reveals that successful VBHC implementation hinges on alignment across clinical, organizational, and policy domains. RT, as an innovative and interdependent specialty, exemplifies both the challenges and opportunities of VBHC in practice. The findings underscore the importance of shared definitions of ‘’value’’ to avoid misalignment and support coherent policy translation. Future research should explore how these conceptualizations
