Area of Science:

  • Oncology
  • Surgical Oncology
  • Medical Physics

Background:

  • Chest wall tumors often require complex surgical interventions.
  • Accurate placement of brachytherapy catheters is crucial for effective tumor irradiation.
  • Traditional methods may face challenges in securing catheters in compromised surgical beds.

Observation:

  • A novel technique utilizing absorbable mesh for suturing afterloading catheters was employed.
  • Patients underwent tumor resection followed by mesh application to the tumor bed.
  • Nylon flexiguide afterloading catheters were secured within the mesh layers.

Findings:

  • Radiographic and CT imaging confirmed stable catheter and seed positioning.
  • Dosimetric analysis showed negligible dose alterations due to catheter movement.
