    • Abstract

    Background
    In this study we evaluated the feasibility and outcome of stereotactic body radiotherapy (SBRT) for lung tumors treated with helical tomotherapy.

    Methods
    Between December 2007 and January 2013, 26 Patients with a total of 49 lung tumors were treated with helical tomotherapy at a median 75 Gy of 10 fractions over 2 weeks. Thirteen lung lesions of primary lung tumors (group 1) and 36 of recurrent or metastatic lung tumors (group 2) were analyzed. Three patients received re-SBRT due to local recurrence after first SBRT were included. (Total 29 cases were analyzed). Radiation pneumonitis was graded according to the Common Terminology Criteria for Adverse Events V 4.0.

    Results
    The patients’ age was median 72 years (range, 47-82). Median follow up was 16 months (range, 2-57 months). Total 13 cases (45%) showed progressive disease after SBRT, and one of them was distant metastasis. Of 12 thoracic recurrences, in-field recurrences were noted in 5 patients and out-field recurrences in 7 patients. In group 1 (13 cases), there were 3 recurrences with 1 in-field thoracic recurrence, 1 out-field thoracic recurrence and 1 distant metastasis. Grade≥2 radiation pneumonitis was noted in 8 patients (30%). One patient died due to radiation pneumonitis at 2 months follow up after second SBRT.

    Conclusion
    The preliminary findings of our study suggest SBRT with helical tomotherapy is feasible for lung tumor treatment. But further studies with more patients and longer follow-up duration are required.
