Medical records were retrospectively reviewed. The endpoints of this study were local control, overall survival (OS), disease-free survival (DFS), local relapse free-survival (LRFS), and treatment toxicity.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>A total of 113 liver and 26 lung metastatic lesions in 52 men (58%) and 38 women (42%) were treated. Median follow-up was 17 months. Median age at treatment was 65 years (range, 23\u201384 years). Primary cancers were 63 GI, three lung, eight breast, four melanoma, three neuro-endocrine tumors, and three sarcomas. Median diameter of the lesions was 28 mm (range, 7\u2013110 mm) for liver and 12.5 mm (range, 5\u201363.5 mm) for lung. Local control rates at 1 and 2 years were 84.5% and 66.1%, respectively. Two-year overall survival rate was 70% (95% CI: 55\u201381%). The 1 and 2-year disease-free survival rates were 27% (95% CI: 18\u201337%) and 10% (95% CI: 4\u201320%), respectively. Median duration of disease-free survival was 6.7 months (95% CI: 5.1\u20139.5 months). Observed toxicities included grade 1\u20133 acute toxicities. One grade 3 and no grade 4 toxicity were reported.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>High-dose SBRT for metastatic lesions is both feasible and effective with high local control rates. Overall survival is comparable with other available techniques. Treatment is well tolerated with low toxicity rates. It could represent an interesting treatment option for oligometastatic patients not amenable to surgery, even when patients had been pre-treated with chemotherapy.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Summary<\/jats:title>\n            <jats:p>Stereotactic body radiotherapy (SBRT) has previously been successfully used in the treatment of metastatic lesions. It could be considered as a curative option for oligometastatic patients. This retrospective study involved 90 patients, designed to test potential effectiveness of SBRT in the treatment of oligometastases irrespective of primary. Results suggest SBRT could be an effective treatment extending patients\u2019 life span. This treatment appears to be more effective when used prior to multiple systemic treatment regimens.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1186\/1748-717x-7-164","type":"journal-article","created":{"date-parts":[[2012,9,27]],"date-time":"2012-09-27T22:58:18Z","timestamp":1348786698000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":44,"title":["A single-institution study of stereotactic body radiotherapy for patients with unresectable visceral pulmonary or hepatic oligometastases"],"prefix":"10.1186","volume":"7","author":[{"given":"Ingrid","family":"Fumagalli","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean-Emmanuel","family":"Bibault","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sylvain","family":"Dewas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew","family":"Kramar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xavier","family":"Mirabel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bernard","family":"Prevost","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Lacornerie","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hajer","family":"Jerraya","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eric","family":"Lartigau","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2012,9,27]]},"reference":[{"issue":"1","key":"660_CR1","doi-asserted-by":"crossref","first-page":"164","DOI":"10.1200\/JCO.2001.19.1.164","volume":"19","author":"KK Herfarth","year":"2001","unstructured":"Herfarth KK, Debus J, Lohr F, Bahner ML, Rhein B, Fritz P, et al.: Stereotactic single-dose radiation therapy of liver tumors: results of a phase I\/II trial.
