- Public TitlePrecision Radiotherapy for Metastases to the Lung.
- Scientific TitleStereotactic Radiotherapy for Metastases to the Lung.
- hypothesisRadiotherapy involving a high biological dose with a limited treatment volume achieves a local tumor control rate of at least 90% in patients with metastatic cancer to the lung.
- Healt Condition(s) or Problem(s) studiedMetastasis, Lung, Oligometastases
- Inclusion criteria1. Minimal life expectancy of 6 months;
2. WHO 0-3;
3. Metastatic disease limited to a maximum of 2 organs;
4. No more than 5 metastatic lesions and a controlled primary tumor site;
5. Diagnostic imaging includes at least a PET-scan and CT ¨Cthorax/abdomen, of which one is not older than 4 weeks at the time of referral for SBRT;
6. Primary tumor must be treated at least 4 months before the diagnosis of the metastasis;
7. Patients are discussed in a multidisciplinary team, including a pulmonologist and/or medical oncologist;
8. Patients with more than 2 lung metastases should be treated with a first line chemotherapeutical agent prior to stereotactic radiotherapy in all cases unless the patient is not suitable for chemotherapy;

- Target number of participants30
- InterventionsPatients are treated with 1-7 fractions of stereotactic radiotherapy using the CyberKnife. The treatment schedule will depend on the tumor location and size.
1. Peripheral tumors >3cm: 3 fractions of 20 Gy (60Gy).
2. Peripheral tumors <3cm: Single dose of 30 Gy (30Gy).
3. Central tumors: 5 fractions of 12 Gy (60Gy).
4. Mediastinal tumors: 7 fractions of 8 Gy (56Gy).

Prior to treatment with the CyberKnife, markers will be placed into/or near the tumor in order to enable "tumor tracking". This enables the CyberKnife to precisely deliver a high radiation dose.
Markers are placed using one of the following approaches: via bronchoscopy, vascular placement (catheterization), or intra- or extra-pulmonary marker placement.

No control group
- Primary outcomeLocal tumor control rate at 1 year.
Sample size was calculated with P0=70%, P1=90%, and alpha/beta =0.10.
1. P0= largest probability of Local Tumor Control that implies that therapeutic activity is too low and does not warrant further investigation;
2. P1= smallest probability of Local Tumor Control that implies that therapeutic activity is sufficient to warrant further investigation.
- Secondary outcome1. Overall surival (at one and two years);
2. Progression-free survival (at one and two years);
3. Treatment related toxicity (acute at 6 months; Late at 2 years).
- TimepointsTimepoints of primary and secondary outcomes: See above.

Follow up:
Pulmonary function tests and CT-scans will be done four times during the first year, twice during the second year, and once during the third year of follow-up.

- Brief summaryObjective:
To determine whether stereotactic radiotherapy achieves a local tumor control rate comparable to surgery (i.e. 90%) in patients with metastatic disease.
Study design:
Non-randomized, single center prospective phase II trial.
Study population:
Patients with limited metastatic lung disease who are inoperable or refuse surgery. Inclusion criteria include: a minimal life expectancy of 6 months, metastatic disease to maximum 2 organs, <5 metastatic lesions, and an interval between treatment of the primary tumor and diagnosis of the metastases of minimal 4 months.
1-7 fractions of stereotactic radiotherapy depending on tumor size and location. Placement of markers into/near the tumor prior to radiation therapy.
Primary outcome:
Local tumor control at one year.
Secondary outcome:
Overall and progression-free survival and treatment-related toxicity.
