Colorectal Liver Metastases SBRT Outcomes with Dosimetric Predictors

A single-institution retrospective study of 116 patients with 128 colorectal liver metastases treated with stereotactic body radiation therapy. The dataset includes clinical variables and dosimetric factors analyzed for their association with freedom from local progression, with a median follow-up of 22.3 months.

Use Cases

• Predicting freedom from local progression based on dosimetric plan quality metrics like Dmin and Dmax.
• Identifying prognostic factors for cancer treatment outcomes using clinical variables such as metastasis extent and systemic therapy lines.
• Validating the role of minimum dose to the planning target volume as a predictor beyond nominal prescription dose.
• Comparing patient outcomes using cut-point analysis on dosimetric variables like the 100 Gy BED10 threshold for PTV Dmin.

Strengths

• Includes data from 116 patients with 128 treated lesions, providing a substantive clinical cohort.
• Analyzes multiple specific dosimetric factors (Dmax, Dmin, Dmean, D2%, D95%, D98%, D99%) and clinical variables.
• Reports specific statistical results, including hazard ratios and confidence intervals for key predictors.

Limitations

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