The current standard treatment in mediastinal non\u2010seminomatous germ cell tumors is chemotherapy combined with postchemotherapy residual mass resection. We report on seven cases of primary mediastinal yolk sac tumor treated with platinum\u2010based chemotherapy and extended resection.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We experienced seven cases of primary mediastinal yolk sac tumor between August 2014 and August 2017. All cases had markedly raised \u03b1\u2010fetoprotein and normal \u03b2\u2010human chorion gonadotropin. Computed tomography scan revealed an anterior mediastinal tumor in all cases. Five patients underwent needle core biopsy, which showed a mediastinal yolk sac tumor. They received preoperative platinum\u2010based chemotherapy and then underwent extended resection, and four of them received postoperative platinum\u2010based chemotherapy. Two other patients did not receive preoperative biopsy, and they underwent surgical extended resection and then received postoperative platinum\u2010based chemotherapy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Two patients (29%) experienced a postoperative complication, including one pneumonia and one atelectasis. There were no operative deaths. R0 resection was achieved in six patients (86%), and R2 resection was achieved in the other patient. Three patients experienced pulmonary metastases within one year, and two of them soon died. Four other patients were alive without recurrence at the time of writing.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Primary mediastinal yolk sac tumor is rare, and the prognosis is poor. A multimodality aggressive approach including adjuvant chemotherapy followed by surgical resection is the optimal treatment and may lead to long\u2010term survival.<\/jats:p><\/jats:sec>","DOI":"10.1111\/1759-7714.12591","type":"journal-article","created":{"date-parts":[[2018,1,10]],"date-time":"2018-01-10T15:33:36Z","timestamp":1515598416000},"page":"491-494","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Primary mediastinal yolk sac tumor treated with platinum\u2010based chemotherapy and extended resection: Report of seven cases"],"prefix":"10.1111","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8271-4530","authenticated-orcid":false,"given":"Bing","family":"Liu","sequence":"first","affiliation":[{"name":"Department of Thoracic Surgery, Peking University First Hospital Peking University  Peking China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gang","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery, Peking University First Hospital Peking University  Peking China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jingwei","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery, Peking University First Hospital Peking University  Peking China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haibo","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery, Peking University First Hospital Peking University  Peking China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xueqian","family":"Shang","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery, Peking University First Hospital Peking University  Peking China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jian","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery, Peking University First Hospital Peking University  Peking China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,1,10]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00292-016-0196-2"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/PAP.0b013e31803240e6"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.urolonc.2010.08.005"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.12659\/AJCR.904855"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1186\/1756-0500-7-803"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1136\/bcr-2014-204662"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-4975(99)01472-1"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5223(99)70015-2"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11748-008-0375-z"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.1994.12.7.1390"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2002.07.062"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1038\/bjc.1995.85"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1093\/jnci\/92.1.54"}],"container-title":["Thoracic Cancer"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2F1759-7714.12591","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/1759-7714.12591","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,24]],"date-time":"2023-09-24T12:57:56Z","timestamp":1695560276000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/1759-7714.12591"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,1,10]]},"references-count":13,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2018,4]]}},"alternative-id":["10.1111\/1759-7714.12591"],"URL":"https:\/\/doi.org\/10.1111\/1759-7714.12591","archive":["Portico"],"relation":{},"ISSN":["1759-7706","1759-7714"],"issn-type":[{"value":"1759-7706","type":"print"},{"value":"1759-7714","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,1,10]]},"assertion":[{"value":"2017-10-28","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2017-12-09","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2018-01-10","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
