    • Abstract

    Background
    INTRODUCTION: Oligometastasic pathology has become a usual pathology present in our clinical routine activity.Although invasive treatments are available, SBRT is a non invasive therapy which can be a viable treatment of choice.We introduce our preliminary study of pulmonary lesions treated using a single fraction of 34Gy OBJECTIVES: The main goal of this report is to demonstrate that a fraction of 34Gy is a viable and attainable therapy to treat lesions in oligometastasic patient’s lungs

    Methods
    Seven patients with 7 pulmonary lesions were treated with single dose of 34Gy. Inclusion criteria were : lesion size smaller than 2 cm , distance from the chest wall and main bronchus tree higher than 2 cm , primary tumor under control in PET scan. Mean Age 61.57y (r39-82), Gender distribution 3 women and 4 men, Histology: 4 cases (57.14% were Metastasic lesions from Colon), 1 metastasic from Adenoid Cystic, 1 Adenocarcinoma from Lung and 1 NSCLC. All patients underwent 4DCT for contouring. Inmobilization was done by thermoplastic mask (Lorca Marin) . Dosimetric characteristics: Mean volume of GTV 1.46cc (r 0.6-4.1), mean volume of PTV 11.29cc (r7.1-22.2), D Max oesophagus 5.06 (r 2.6-8.4), D max Heart 4.05 (r6.86-17.0), D max trachea 5.12 Gy (r 0.3-11.1), Dmax skin 10.98(r7.0-14.4). Patients were treated using True Beam machine. In 6 cases treatments were delivered without flattering filter beams

    Results
    After 6 months of follow up (r 6-2.19) no toxicity higher than grade 2 was detected. Local control rates and survival are 100%, 100% respectively. To sum up, even this is a preliminary study, seems than long term results can show us a new perspective in these oligometastasic patients.

    Conclusion
    not applicable
