About this trial
This is an interventional treatment trial for Non-small Cell Lung Cancer focused on measuring Non-small call lung cancer, Medically inoperable, Stage one, Radiotherapy, SBRT, Hypofractionation, Conventional fractionation
Eligibility Criteria
Inclusion Criteria:

- Medically inoperable patients or patients refusing surgery.
- Morphologically verified. If that is impossible there must be increased tumour size in repeated CT scans and positive PET.
- Patients should have a life expectancy of > 6 months.
- WHO performance status 0-2.
- Signed written informed consent obtained.
- Patient should be feasible for both study arms.
Exclusion Criteria:
- Patients with central tumour growth adjacent to trachea, main bronchus or esophagus.
- Maximal tumour diameter > 6 cm.
- Patients with prior malignancy within the last five years (except basal cell carcinoma of the skin or in situ carcinoma of the cervix).
- Any prior antitumoral treatment of the present lung cancer.
- Previous irradiation that included part of the lung.
- Pregnant women.

Stereotactic radiotherapy
Conventionally fractionated radiotherapy
Arm A: Stereotactic radiotherapy to a dose of 66 Gy at the isocenter with 22 Gy per fraction in 3 fractions during one week with body frame fixation and a planning target volume with a 5 mm margin around the macroscopic tumour. A heterogeneous dose distribution is used so 45 Gy will cover the PTV.
Arm B: Conventionally fractionated radiotherapy to a dose of 70 Gy with 2 Gy per fraction in 35 fractions during 7 weeks with fixation in a vacuum pillow and a planning target volume with a 2 cm margin around the macroscopic tumour.
