ABSTRACT
Objective: Medically inoperable patients with primary or recurrent lung cancer are increasingly being diagnosed clinically without pathologic confirmation especially for patients with comorbidities that preclude biopsy. The objective of this study is to report the outcomes of medically inoperable patients with unbiopsied primary or recurrent lung carcinoma with SBRT. Methods: From 2008-2011, 22 patients with non-pathologically diagnosed primary or recurrent lung cancer were treated with SBRT. All patients had diagnostic imaging clinically consistent with primary or recurrent lung malignancy. Fifteen patients had primary lung cancer and 7 had recurrent disease previously treated with surgery or fractionated radiotherapy. Median SBRT dose was 50 Gy (Range 40-55 Gy) in a median of 5 fractions (Range 4-10 fractions). Median BED was 100 Gy (Range 72-151.2 Gy). Results: Median follow up is 15.3 months (Range 6.6-33.0 months). Primary tumors had a median longest dimension on the original CT of 1.6cm, which enlarged to 2.0cm (P
