Phase II Study of Accelerated Hypofractionated Three-Dimensional Conformal Radiotherapy for Stage T1-3 N0 M0 Non–Small Cell Lung Cancer: NCIC CTG BR.25

This multi-institutional phase II trial (80 patients from 17 Canadian institutions) was performed to assess if a hypofractionated accelerated radiotherapy regimen for cytohistological-proven early stage NSCLC (peripherally located T1 to T3 N0 M0) has a good local control rate. They concluded that delivering 60 Gy in 15 fractions using a simple three-dimensional conformal radiotherapy technique resulted in favorable outcomes in patients with NSCLC who were medically inoperable or refused surgery.  The actuarial rate of primary tumor control was 87.4%  and overall survival was 68.7% at 2 years. This approach may be a good option for those centers that do not have SBRT/SABR capability.
