Thirty-five of the 93 patients were referred before breast surgery (PreS), and 58 patients were referred after surgery (PostS). The time periods from initial diagnosis (ID) to initiation of OS (42.6 \u00b1 27.7 days for PreS v 71.9 \u00b1 30.7 days for PostS; P &lt; .001) and from ID to initiation of chemotherapy (83.9 \u00b1 24.3 days for PreS v 107.8 \u00b1 42.9 days for PostS; P = .045) were significantly shorter for the PreS group versus the PostS group. Nine (25.7%) of 35 patients in the PreS group versus one (1.7%) of 58 patients in the PostS group were able to undergo two FP cycles (P &lt; .001), resulting in an increased yield of oocytes in the PreS group (18.2% [93 of 511 oocytes] v 0.6% [five of 800 oocytes], respectively; P &lt; .001) and embryos (17.2% [40 of 233 embryos] v 0.6% [two of 357 embryos], respectively; P &lt; .001). Patients who had an oocyte retrieval within 5 weeks of the surgery were able to complete a second cycle within 9 weeks of the surgery. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p> FP referral before breast surgery enables earlier initiation of cryopreservation cycles and chemotherapy and, when appropriate, multiple FP cycles. Women who can undergo multiple cycles may be at advantage for FP because of a larger number of oocytes or embryos cryopreserved. This is the first study demonstrating the benefit of early FP referral in patients with cancer. <\/jats:p><\/jats:sec>","DOI":"10.1200\/jco.2010.30.5748","type":"journal-article","created":{"date-parts":[[2010,9,28]],"date-time":"2010-09-28T04:55:00Z","timestamp":1285649700000},"page":"4683-4686","source":"Crossref","is-referenced-by-count":123,"title":["Value of Early Referral to Fertility Preservation in Young Women With Breast Cancer"],"prefix":"10.1200","volume":"28","author":[{"given":"Sanghoon","family":"Lee","sequence":"first","affiliation":[{"name":"From the Institute for Fertility Preservation, New York Medical College\/Westchester Medical Center; Graduate School of Basic Medical Sciences, New York Medical College, Valhalla, NY."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sinan","family":"Ozkavukcu","sequence":"additional","affiliation":[{"name":"From the Institute for Fertility Preservation, New York Medical College\/Westchester Medical Center; Graduate School of Basic Medical Sciences, New York Medical College, Valhalla, NY."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elke","family":"Heytens","sequence":"additional","affiliation":[{"name":"From the Institute for Fertility Preservation, New York Medical College\/Westchester Medical Center; Graduate School of Basic Medical Sciences, New York Medical College, Valhalla, NY."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fred","family":"Moy","sequence":"additional","affiliation":[{"name":"From the Institute for Fertility Preservation, New York Medical College\/Westchester Medical Center; Graduate School of Basic Medical Sciences, New York Medical College, Valhalla, NY."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kutluk","family":"Oktay","sequence":"additional","affiliation":[{"name":"From the Institute for Fertility Preservation, New York Medical College\/Westchester Medical Center; Graduate School of Basic Medical Sciences, New York Medical College, Valhalla, NY."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"233","reference":[{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2007.14.8700"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2006.06.5888"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1634\/theoncologist.11-5-422"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.1093\/humupd\/dmh021"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2009.24.2057"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.1210\/jc.2006-0962"},{"key":"B8","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2005.05.037"},{"key":"B9","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2005.01.6089"},{"key":"B10","doi-asserted-by":"publisher","DOI":"10.1038\/sj.bjc.6602734"},{"key":"B11","doi-asserted-by":"publisher","DOI":"10.1016\/j.fertnstert.2005.03.013"},{"key":"B12","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2009.23.0250"},{"key":"B13","first-page":"203","volume":"54","author":"Forman EJ","year":"2009","journal-title":"J Reprod Med"},{"key":"B14","doi-asserted-by":"publisher","DOI":"10.1016\/j.fertnstert.2006.03.017"}],"container-title":["Journal of Clinical Oncology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/ascopubs.org\/doi\/pdfdirect\/10.1200\/JCO.2010.30.5748","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,5,25]],"date-time":"2022-05-25T23:45:49Z","timestamp":1653522349000},"score":1,"resource":{"primary":{"URL":"https:\/\/ascopubs.org\/doi\/10.1200\/JCO.2010.30.5748"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,11,1]]},"references-count":13,"journal-issue":{"issue":"31","published-print":{"date-parts":[[2010,11,1]]}},"alternative-id":["10.1200\/JCO.2010.30.5748"],"URL":"https:\/\/doi.org\/10.1200\/jco.2010.30.5748","relation":{},"ISSN":["0732-183X","1527-7755"],"issn-type":[{"value":"0732-183X","type":"print"},{"value":"1527-7755","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,11,1]]}}}
