Video-Assisted Thoracic Surgery (VATS) was performed in 83.9% of cases. Surgical resection was achieved by wedge in 73.5%, segmentectomy in 7.4%, lobectomy in 17.9% and pneumonectomy in 1.2% of cases. The median durations of hospital stay and of drainage were 4\u00a0days (IQR 3\u20137) and 1\u00a0day (IQR 1\u20132), respectively. During the follow-up (median 31\u00a0months; IQR 15\u201358), 93 patients (57.4%) presented recurrences and repeated PM could be realized in 35 patients (21.6%) achieved by VATS in 77.1%. Non-colorectal tumour (HR 1.84), age\u2009&lt;\u200970\u00a0years (HR 1.77) and previous extra-thoracic metastases (HR 1.61) were identified as prognostic factors of recurrence. Overall survival at 5-year was estimated at 67%. Non-colorectal tumour (HR 2.40) and mediastinal lymph nodes involvement (HR 3.42) were significantly associated with an increased risk of death.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Despite high recurrence rates after PM, surgical resection shows low morbidity rate and acceptable long-term survival, thus should remain the standard treatment for single pulmonary metastases.<\/jats:p>\n                <jats:p><jats:italic>Trial registration<\/jats:italic>: The Local Ethics Committee approved the study (No. 2019\u201302,474) and individual consent was waived.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s13019-021-01740-3","type":"journal-article","created":{"date-parts":[[2021,12,28]],"date-time":"2021-12-28T02:02:28Z","timestamp":1640656948000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Survival prognostic and recurrence risk factors after single pulmonary metastasectomy"],"prefix":"10.1186","volume":"16","author":[{"given":"C\u00e9line","family":"Forster","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amaya","family":"Ojanguren","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean Yannis","family":"Perentes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthieu","family":"Zellweger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thorsten","family":"Krueger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Etienne","family":"Abdelnour-Berchtold","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8705-4279","authenticated-orcid":false,"given":"Michel","family":"Gonzalez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,12,28]]},"reference":[{"key":"1740_CR1","doi-asserted-by":"publisher","DOI":"10.2217\/fon-2018-0713","author":"M Gonzalez","year":"2019","unstructured":"Gonzalez M, Zellweger M, Nardini M, et al.
