Area of Science:

  • Oncology
  • Medical Physics
  • Radiation Therapy

Context:

  • The University of Würzburg's radiation therapy department has utilized flexible catheters since 1989.
  • Interstitial brachytherapy in high dose rate (HDR) mode is employed as a primary or adjuvant treatment.

Purpose:

  • To describe the application and outcomes of flexible catheter interstitial brachytherapy.
  • To highlight the technique's efficacy in treating oropharyngeal, oral cavity, pancreatic, and brain tumors.

Summary:

  • Flexible catheters are used for high-dose-rate interstitial brachytherapy, alone or with external beam therapy.
  • The afterloading technique is applied to various cancers including oropharyngeal, oral cavity, pancreatic, and brain tumors.
  • High radiation doses (up to 30 Gy in 10-15 fractions) are delivered over several days to two weeks, with precise dose calculation using radiographs and CT scans.

Impact:

  • Flexible catheters are well-tolerated, allowing for high radiation doses with minimal side effects.
  • Patients experience excellent palliation and can maintain daily activities during treatment.
  • This brachytherapy approach demonstrates significant patient tolerance and effective symptom management.
