Stereotactic Body Radio Therapy (SBRT) for Early-stage Non Small Cell Lung Cancer (NSCLC) (SBRT-NSCLC)
Recruitment status was: Active, not recruiting
The purpose of this study is to evaluate local disease control after 2 years in patients with non-metastatic, non-operated non-small-cell lung cancer treated by radiotherapy.
Eligible patients will be recruited and registered consecutively (no randomization). The estimated inclusion period is approximately 24 months. The duration of the research is 4 years.
The number of patients required in this multicentric prospective study is 120:
- 20 patients in the SBRT-1 arm (cyberknife),
- 80 patients in the SBRT-2 arm (linear accelerator-based)
- 20 patients in the conformational radiotherapy arm.
This is a prospective, multicentric, non comparative and non randomized study.

1 - SBRT using cyberknife
SBRT using cyberknife: treatment = 2x15 Gy during 2 weeks
Radiation: SBRT by cyberknife
treatment = 2x15 Gy during 2 weeks
2 - SBRT using linear accelerator
SBRT using linear accelerator: treatment = 2x15 Gy during 2 weeks
Radiation: SBRT by linear accelerator
treatment = 2x15 Gy during 2 weeks
3 - Conformational radiotherapy
Conformational radiotherapy: treatment = 5x2 Gy during 7 weeks
Radiation: Conformational radiotherapy
treatment = 5x2 Gy during 7 weeks (free breathing or breath holding)
The main objective of this study is to do a health economic evaluation of innovating techniques in radiotherapy.
SBRT is the very precise delivery of high-powered radiation to small target volumes, using multiple low-intensity beams. Extremely precise patient positioning and target location is essential for accurate treatment delivery.
Several studies have shown a benefit of SBRT in terms of local control and progression-free survival, in particular for the treatment of cerebral metastases of limited number and size.
The development of this technique is recent. The number of treatment sessions is low: 1 to 4.
But the patient is exposed to a major risk of toxicity in several organs: the bronchi, the lungs, large vessels, the oesophagus and the spinal-cord.
Pulmonary SBRT imposes strict rules and the use of specific equipment.
Extra-cranial SBRT can be realized using either:
- Conventional linear-accelerator equipped SBRT,
3 groups of treatment will be evaluated in this study:
- SBRT by cyberknife,
- SBRT by linear accelerator,
- Conformational radiotherapy (free breathing or breath holding).
