Outcome measures
Primary outcome
Local 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 outcome
1. 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).
Background summary
Objective:
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.
Intervention:
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.
Study objective
Radiotherapy 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.
Study design
Timepoints 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.
Intervention
Patients 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.
