Stereotactic Body Radiation Therapy Is Effective and Safe in Patients with Early-Stage Non-Small Cell Lung Cancer with Low Performance Status and Severe Comorbidity
BACKGROUND: The purpose of this study was to assess stereotactic body radiation therapy (SBRT) results and toxicity for stage I non-small cell lung cancer patients with low performance status and severe comorbidity. PATIENTS AND METHODS: From September 2008 to April 2010, 36 patients with 38 lesions...

description | BACKGROUND: The purpose of this study was to assess stereotactic body radiation therapy (SBRT) results and toxicity for stage I non-small cell lung cancer patients with low performance status and severe comorbidity. PATIENTS AND METHODS: From September 2008 to April 2010, 36 patients with 38 lesions were treated with hypofractionated SBRT. All except one were medically inoperable, had low performance status and/or severe cardiovascular and/or cardiopulmonary comorbidity. The patients were immobilized in an Elekta stereotactic body frame to improve setup accuracy, and four-dimensional CT scans were used for target delineation. Fractions of 15 Gy were prescribed to cover the planning target volume, giving a total dose of 45 Gy, with 1 fraction every second day. Cone beam CT was applied at each fraction to correct for setup errors. The patients were followed with toxicity evaluation and radiographic follow-up. RESULTS: Median follow-up time was 13.8 months (0–21 months). The local tumor control after 12 months was 100%. Four patients developed regional relapse about 12 months after SBRT. The 1-year disease-free survival was 83%. The median tumor shrinkage at 1 year was 22 mm. Three patients experienced systemic relapse after 13 months. One patient developed grade 3 chest pain toxicity and 16 patients reported temporary grade 1 chest pain toxicity. Two patients reported temporary increased dyspnea. No patient experienced a reduction of the performance status after SBRT. CONCLUSION: SBRT is an effective and safe treatment modality for elderly patients with early-stage non-small cell lung cancer, having low performance status and severe comorbidity. It is possible to achieve high local control rates with good tolerance. |
