The presence of an associated soft tissue mass in low\u2010intermediate grade lesions was not associated with increased recurrence.

Despite a higher rate of positive margins for low\u2010intermediate grade lesions of the scapula, there was no significant difference in survival compared to low\u2010intermediate grade lesions of the pelvis. Additional studies with larger sample sizes are needed to further elucidate differences between these locations.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/jso.28023","type":"journal-article","created":{"date-parts":[[2024,11,28]],"date-time":"2024-11-28T23:59:44Z","timestamp":1732838384000},"page":"925-931","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Chondrosarcoma of the Flat Bones: Differential Survival Between High\u2010Grade Lesions of the Pelvis and Scapula"],"prefix":"10.1002","volume":"131","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3769-016X","authenticated-orcid":false,"given":"Mikaela H.","family":"Sullivan","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery Mayo Clinic Rochester Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4192-4133","authenticated-orcid":false,"given":"Samuel E.","family":"Broida","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery Mayo Clinic Rochester Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emmett J.","family":"Cleary","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery Mayo Clinic Rochester Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter S.","family":"Rose","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery Mayo Clinic Rochester Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0390-1018","authenticated-orcid":false,"given":"Matthew T.","family":"Houdek","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery Mayo Clinic Rochester Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,11,28]]},"reference":[{"issue":"8","key":"e_1_2_8_2_1","first-page":"1248","article-title":"Chondrosarcoma of Bone.
