Dosimetric Criteria for Organs at Risk in Left Breast Cancer Radiotherapy

Twenty patients with stage I left-sided breast cancer were retrospectively selected from a hospital database for exploratory dosimetric analysis between May 2022 and May 2023. The dataset compares dosimetric parameters for planning target volumes and organs at risk, as well as beam-on and total treatment times, between two radiotherapy plans using the deep inspiration breath-hold technique. Author Yucheng Li published the data on figshare under a CC-BY-4.0 license.

Use Cases

• Compare conformity index and dose parameters for planning target volumes between continuous semi-arc and tangent-arc plans.
• Analyze radiation exposure to organs at risk, such as the heart and lungs, using deep inspiration breath-hold.
• Examine trends in treatment session duration and patient adaptation across multiple fractions.
• Benchmark dosimetric outcomes for stage I left-sided breast cancer radiotherapy in a single-institution study.

Strengths

• Includes data from 20 patients, providing a basis for exploratory analysis.
• Compares two specific radiotherapy plans (continuous semi-arc and tangent-arc) on multiple dosimetric and temporal parameters.
• Contains specific statistical results, such as a significant difference in conformity index (P < 0.05) between plans.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The exploratory findings are based on a limited sample size from a single institution, as noted by the author.
