Tumour ablation for lung cancer

Overview

At Royal Brompton Hospital, we are are able to ablate some forms of lung cancer using bronchoscopy and interventional radiology techniques.

This treatment is completed using bronchoscopy, by passing a bronchoscope through the mouth or nose and down the throat to reaching directly into the lungs.

This bronchoscopic technique usually occurs in cases where the tumours are blocking off part of the main airways, causing problems with breathing.

The suitability of this procedure to treat lung cancer will depend on the type and location of the tumour and the way in which this appears on a CT scan.

Techniques to ablate lung cancer

Treatment can be carried out using a range of techniques. These include:

Cryotherapy

This treatment of cryotherapy uses cold temperatures from a freezing probe applied to areas of abnormal airway, lung or tumour. The freezing process causes some of the tumour to stick onto the probe and this can then be removed from the airway.

Diathermy

This treatment (also known as electrocautery or thermocautery) involves applying heat, through an electrical current, to burn and remove the tumour from within the airways.

Microwave ablation

This treatment uses high frequency microwave energy to create heat, which is used to kill cancer cells. This can also be completed percutaneously, by inserting a probe through the skin of the chest and directly into the tumour.

Stent insertion

Self-expanding metallic stents are placed to keep the main airway(s) open.

Targeted lung denervation

A bronchoscopic electrode delivers radiofrequency energy to interrupt the nerves located just outside the airway. This leads to a relaxation and opening of the airways.
