Stereotactic Body Radio Therapy (SBRT) for Early-stage Non Small Cell Lung Cancer (NSCLC)

Not Applicable
Conditions
Non Small Cell Lung Cancer
Interventions
Radiation: SBRT by cyberknife
Radiation: SBRT by linear accelerator
Radiation: Conformational radiotherapy
Registration Number
NCT00870116
Lead Sponsor
Centre Leon Berard
Brief Summary

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.

Detailed Description

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,

* Cyberknife 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).
