Therefore, the aim of this study was to evaluate the outcome of patients with intrathoracic sarcoma treated at an academic referral center over a 21-year period.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A retrospective search was performed to identify patients with intrathoracic sarcomas treated with surgical resection from January 1990 to November 2011 at the University of Washington Medical Center. Local control and overall survival were analyzed in relation to the treatment received.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Thirty-five patients were identified. Hazard ratios for local control, adjusted for tumor margin status, at 5\u00a0years were 0.74 (95\u00a0% CI [0.21, 2.58]) for the addition of chemotherapy (CT) to surgery, 0.57 (95\u00a0% CI [0.15, 2.23]) with the addition of (radiation therapy) RT, and 0.50 (95\u00a0% CI [0.06, 4.03]) with the addition of both CT and RT. At 7\u00a0years, the ratios for local control were 0.69 (95\u00a0% CI [0.20, 2.36]) for CT added to surgery, 0.58 (95\u00a0% CI [0.15, 2.27]) for RT, and 0.41 (95\u00a0% CI [0.05, 3.33]) with the addition of both CT and RT. Hazard ratios for overall survival, adjusted for sarcoma stage, at 5\u00a0years were 0.61 (95\u00a0% CI [0.16, 2.39]) for the addition of CT to surgery, 1.03 (95\u00a0% CI [0.26, 4.08]) for the addition of RT, and 0.54 (95\u00a0% CI [0.11, 2.69]) for the addition of both CT and RT. The 7-year hazard ratios for overall survival were 0.77 (95\u00a0% CI [0.23, 2.60]) for CT added to surgery, 0.99 (95\u00a0% CI [0.25, 3.84]) for the addition of RT, and 0.42 (95\u00a0% CI [0.09, 2.05]) for both CT and RT with surgery. At 10\u00a0years, hazard ratios for overall survival were 0.71 (95\u00a0% CI [0.21, 2.38]) for added CT, 0.81 (95\u00a0% CI [0.21, 3.08]) for added RT, and 0.33 (95\u00a0% CI [0.07, 1.65]) for the addition of both CT and RT to surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our series is the largest published study of intrathoracic sarcoma which focuses on the survival benefit of adding RT, chemotherapy or both to surgery in resectable intrathoracic sarcoma. Our data suggest a potential benefit in local control and survival from adjuvant therapy, with the greatest benefit likely to come from combined CT and RT, though none of the results achieved statistical significance. As intrathoracic sarcomas are rare and histologically heterogeneous, larger collaborative studies are necessary to determine treatment efficacy and elucidate which histologic subtypes are likely to benefit most from adjuvant therapy.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s13566-015-0236-1","type":"journal-article","created":{"date-parts":[[2015,12,16]],"date-time":"2015-12-16T13:13:17Z","timestamp":1450271597000},"page":"169-177","update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Treatment of resectable intrathoracic sarcomas: a single institution experience over twenty years"],"prefix":"10.1007","volume":"5","author":[{"given":"David","family":"Rainey","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jacob","family":"Berriochoa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Korpak","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing","family":"Zeng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elizabeth T.","family":"Loggers","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robin L.","family":"Jones","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shilpen","family":"Patel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2015,12,16]]},"reference":[{"key":"236_CR1","unstructured":"Howlader N, Noone AM, Krapcho M, Neyman N, Aminou R, Altekruse SF, Kosary CL, Ruhl J, Tatalovich Z, Cho H, Mariotto A, Eisner MP, Lewis DR, Chen HS, Feuer EJ, Cronin KA (eds).
