Small Bowel Dose-Volume Histograms for Post-Hysterectomy Proton Therapy Patients

A study of 11 post-hysterectomy patients with gynecologic cancers enrolled in an image-guided proton therapy protocol. Data includes computed tomography simulations with full and empty bladders, weekly/biweekly on-treatment scans, and comparative intensity-modulated radiation therapy plans. The research investigates the impact of organ motion on small bowel dose-volume relationships.

Use Cases

• Comparing small bowel dose-volume histograms between pencil beam scanning proton therapy and intensity-modulated radiation therapy based on the study's comparative analysis.
• Analyzing the impact of bladder volume changes on small bowel dose estimates based on the described association.
• Evaluating different small bowel contouring strategies (bowel loops vs. bowel bag) for dose estimation based on the methodology.
• Investigating organ motion effects on dose-volume relationships during radiation therapy based on the study's background.

Strengths

• Includes data from 11 patients, providing a basis for matched-pair statistical comparisons.
• Contains multiple imaging time points per patient, including simulation and on-treatment scans.
• Compares two radiation therapy modalities (PBS and IMRT) and two contouring strategies.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
