Table 1_Paired dosimetric comparison of VMAT-based total body and total marrow irradiation

Thirty adult acute leukemia patients form a paired dosimetric comparison of volumetric modulated arc therapy (VMAT) for total body and total marrow irradiation. The dataset, authored by Sevim Sahin and last updated in June 2026, shows TMI plans significantly reduced organ-at-risk doses by approximately 5–6 Gy for the heart, kidneys, and liver. Plan quality and complexity metrics, including monitor units and modulation factor, are also compared.

Use Cases

• Compare organ-at-risk dose sparing between TBI and TMI techniques based on the paired patient data.
• Analyze the relationship between plan complexity metrics like modulation factor and treatment technique.
• Evaluate the potential impact of AI-based auto-segmentation on planning efficiency for skeletal targets.
• Benchmark VMAT plan quality using metrics such as the homogeneity index described in the study.

Strengths

• Includes data from 30 paired patient plans, enabling direct comparison of two radiotherapy techniques.
• Plan assessment uses multiple concrete metrics: homogeneity index, monitor units, segment number, and modulation factor.
• Results show statistically significant (p < 0.001) dose reductions to organs at risk with TMI.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 19.4 KB, indicating limited scope.
