      P1.05-22 - New Methods of Brachyradiotherapy Catheter Stabilization in the Airways (ID 14116)

      • Abstract


      Endobronchial brachytherapy(EBBT) is mainly used for palliation of obstructive symptoms, most commonly

      for malignancies located in the central airways (ei. trachea and main bronchi). However, the EBBT

      has a curative potential in those tumors, which are small to moderate in size, are not metastasized to

      the lymph nodes and are other wisely untreatable. Typically, EBBT is indicated in patients diagnosed

      with locally advanced non-small cell lung carcinoma (NSCLC) in the central airways.

      Endobronchial brachytherapy, as other methods of interventional bronchoscopic procedures such as

      use of laser, cryo or electrotherapy, and variations of mechanical airways passage maintenance, should

      not be understood as a marginal option from the modalities list. All of these mentioned methods are

      complementary and by a combination, one can achieve satisfactory clinical results

      Two new methods of brachyradiotherapy catether fixation are described . First one utilises unique star-shaped fixation device manually made from Microtech stent holding 5Fr probe in the center of airways. In the second case the brachytherapy catheter was fixed in the designated position in the trachea using a Novatech-Dumon stent (20x40 mm) and consecutively, single-dose brachytherapy of 8 Gy was applied.

      In both our referred cases, the patients undergone procedure of HDR-EBBT without

      any complication with the use of a fixation devices which kept an afterloading probe in selected area

      of the airways and allowed a symmetrical radiation distribution

      In our presented case studies local control of intraluminal tumor growth has been achieved with the HDR-EBBT. In

      the case of our first patient along with surgery and cryotherapy and in the other case along with the

      third-line chemotherapy based on docetaxel.
