But the university has said little else about what, if anything, it has done to address the allegations.<\/p>\n<\/div>\n<aside class=\"css-ew4tgv\" aria-label=\"companion column\"\/><\/div>\n<div data-testid=\"companionColumn-1\">\n<div class=\"css-53u6y8\">\n<p class=\"css-at9mc1 evys1bk0\">Since the Times article in February, Dr. Yoon\u2019s name has been changed from Sam Yoon to S. Sunghyun Yoon on a <a class=\"css-yywogo\" href=\"https:\/\/columbiasurgery.org\/sam-yoon-md\" title=\"\" rel=\"noopener noreferrer\" target=\"_blank\">Columbia website<\/a> advertising surgical treatment options. Because of the change, the Columbia surgeon who is being promoted to many patients has a name that no longer matches the one Dr. Yoon used to publish his retracted studies. A <a class=\"css-yywogo\" href=\"https:\/\/columbiasurgery.org\/news\/columbia-creates-new-surgical-oncology-division-under-dr-sam-yoon\" title=\"\" rel=\"noopener noreferrer\" target=\"_blank\">Columbia hiring announcement<\/a> from several years ago was also recently edited to change the rendering of Dr. Yoon\u2019s name, according to web page archives.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Columbia said that faculty members were responsible for any name changes on departmental web pages. The university declined to comment on the retractions. Memorial Sloan Kettering Cancer Center, where Dr. Yoon worked when much of the questionable research was done, also declined to comment, saying only that it reviews such cases.<\/p>\n<div class=\"css-1336jj\">\n<div class=\"css-121kum4\">\n<div class=\"css-asuuk5\"><noscript><\/p>\n<div class=\"css-7axq9l\" data-testid=\"optimistic-truncator-noscript\"><svg width=\"24\" height=\"24\" viewbox=\"0 0 24 24\" aria-hidden=\"true\" class=\"css-1b5b8u1\"><path fill=\"currentColor\" fill-rule=\"evenodd\" d=\"M2.5 12a9.5 9.5 0 1 1 19 0 9.5 9.5 0 0 1-19 0Zm8.5 1.75v-7.5h2v7.5h-2Zm0 2v2h2v-2h-2Z\" clip-rule=\"evenodd\"\/><\/svg><\/p>\n<div data-testid=\"optimistic-truncator-noscript-message\" class=\"css-6yo1no\">\n<p class=\"css-3kpklk\">We are having trouble retrieving the article content.<\/p>\n<p class=\"css-3kpklk\">Please enable JavaScript in your browser settings.<\/p>\n<\/div>\n<\/div>\n<p><\/noscript><\/p>\n<div class=\"css-1dv1kvn\" id=\"optimistic-truncator-a11y\" tabindex=\"-1\">\n<hr\/>\n<p>Thank you for your patience while we verify access.
