ENDOBRONCHIAL BRACHITHERAPY WITH Ir192 HDR IN BRONCHIAL CANCER

Using a high activity Ir 192 movable source ( ~ 10 Curios) through the inside of a plastic probe (2-3 mm diameter), we can radiate the intraluminal tumour of the bronchus, with a very high dose, without radiating the structure and neighbouring organs.

Technique

• The technique is carried out without general anaesthesia, only with light sedation and local anaesthesia.

• Fluoroscopy guided by bronchoscopy, placing the probe inside the affected bronchus.

• Ortogonal XR for tridimensional reconstruction and dosimetry.

• Calculated dose 1 cm from the axis in the centre of the Ir source movement.

Indications

• It is indicated as an exclusive treatment in early intraluminal tumours, smaller than 1cm.

• Unoperable tumours for medical reasons, with a general good state. It is used to reinforce overimpression to the external radiotherapy.

• Relapse of the surgical stump, with affected margins after surgery. It is used to reinforce external radiotherapy.

• Palliative treatments in advanced bronchial tumours in which the bronchial lumen is narrowed.

Observations

• 3h of fasting conditions.
• No anaesthesia.
• Total time of the procedure: 30-45 min.
• Out-patient technique.

Team

• Radiotherapist.
• Pneumologist.
• Medical Physicist.
• Oncologic Nurse Team.
