Case Series: Surgeon-Guided CTV Reassessment for Postoperative Chylothorax Radiotherapy

A retrospective case series of eight patients with persistent postoperative chylothorax treated with low-dose radiotherapy at a single institution from January 2019 to July 2022. The data includes surgeon-guided reassessments of clinical target volumes and comparisons with delivered radiotherapy isodose distributions to explore factors associated with treatment outcomes. The dataset was authored by Mu-Chou Lin and is available under a CC-BY-4.0 license.

Use Cases

• Analyzing the relationship between baseline chyle output and radiotherapy response based on the described patient outcomes.
• Investigating coverage gaps in radiotherapy fields for lymphatic regions based on retrospective surgeon-guided CTV reassessment.
• Comparing treatment outcomes between different low-dose radiotherapy fractionation schemes (9 Gy vs. 10 Gy) mentioned in the description.

Strengths

• Includes detailed clinical reassessment by thoracic surgeons for all eight cases.
• Covers a specific patient cohort treated over a defined 3.5-year period (January 2019–July 2022).
• Provides quantitative outcome data, with chylothorax resolution reported for 4 of 8 patients (50%).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The small sample size of eight patients limits statistical power.
