Brief Summary
The role of radiotherapy is well established in the management of early stage lung cancer or as part of a multidisciplinary approach of locally advanced lung cancer (1). Recent advances in Cyberknife© technology, which is a robotic system of stereotactic irradiation including localisation and real time lesion-tracking, has led to an increase in accuracy and potentially in efficiency of the irradiation of tumor field (2)(3). According to several studies, promising results in local control and survival rates have been achieved in patients suffering from primary lung cancer or peripheral lung metastasis treated with Cyberknife© (4)(5)(6)(7)(8). Fiducial markers are implanted in or near a tumor in a configuration defining a COM (center of mass) guiding the Cyberknife for tumor localization. Tumor movement is then synchronized to respiratory cycle motion during treatment which reduces toxicity of non target lung tissue irradiation. Change in marker positioning leads to COM alterations, thus limiting detection by the tracking system. Percutaneous (9)(10)(11) (12), endovascular (12)(13) fiducial implantation or by means of bronchoscopic devices (14)(15)(16)(17)(18) are three techniques that have been validated in previous studies as feasible and safe procedures, providing accurate tracking. Few studies are currently available in the litterature comparing these modalities (19)(20). The percutaneous implantation technique will not be considered for this study because this technique is associated with a high risk of pneumothorax (9). Both the endobronchial and endovascular technique have been described in the literature with equivalent success rate (87-90%) in intention to treat (21)(22). One of the endpoints of this study is to verify that these results are reproducible in our institution where both techniques are currently available and to investigate other secondary endpoints such as fiducial marker migration after placement, complications rates and procedure time.

Study Arms (2)
Endovascular fiducial marker insertion
Fiducial markers are inserted and released near the tumor through femoral puncture. A catheter is led through the venous system to the right heart and from there through the heart into the pulmonary arteries.
Bronchoscopic fiducial marker insertion
Fiducial markers are inserted and released near the tumor into the bronchi using an endoscopic route
Interventions
Fiducial markers will be inserted using an endovascular route
Fiducial markers will be inserted using an endoscopic route
Eligibility Criteria
Patients with lung cancer (1ary and 2ndary), not eligible for surgery, and treated by radiation therapy needing a fiducial marker placement will be eligible for this study which is a prospective randomized controlled trial (endovascular vs endobronchic fiducial marker).
You may qualify if:
- Lung cancer (primary or secondary, any histological type)
- Early stage lung cancer: patients diagnosed with stage I for which operation is contra-indicated, for example because of cardiac or pulmonary comorbidities.
- Locally advanced lung cancer stages II - IIIB
- Metastatic lung cancer stage IV (palliative care)
- y ≤ age ≤ 85 y
You may not qualify if:
- age \<18y
- incapacity of judgment
- Absence of a signed consent form
