A feasibility study of image-guided hypofractionated conformal arc therapy for inoperable patients with localized non-small cell lung cancer.

We treated 36 cases of stage I/II non-small cell lung cancer in inoperable patients. Treatments were planned to a total isocenter dose of 60Gy (8x7.5Gy) based on a dynamic field shaping arc, employing one arc to span as much area as possible and if needed additional weighted segments.
