Various other models of cancer progression and metastasis have been proposed, including parallel evolution and the same gene model. The aim of this study was to investigate the evolution of metastases from primary cancer in 22 patients diagnosed with high\u2010grade serous epithelial ovarian cancer. We established somatic genetic profiles based on the pattern of loss of heterozygosity, in several different regions of tumor tissue within the primary tumor and metastatic deposits from each case. Maximum parsimony tree analysis was used to examine the evolutionary relationship between the primary and metastatic samples for each patient. In addition, we investigated the extent of genetic heterogeneity within and between metastatic tumors compared with primary ovarian tumors. Our data suggest that most, if not all, metastases are clonally related to the primary tumors. However, the data oppose a single model of linear\u2010clonal evolution whereby a late stage clone within the primary tumor acquires additional genetic changes that enable metastatic progression. Instead, the data support a model in which primary ovarian cancers have a common clonal origin, but become polyclonal, with different clones at both early and late stages of genetic divergence acquiring the ability to progress to metastasis. \u00a9 2009 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/ijc.24148","type":"journal-article","created":{"date-parts":[[2008,11,11]],"date-time":"2008-11-11T18:03:52Z","timestamp":1226426632000},"page":"1579-1586","source":"Crossref","is-referenced-by-count":62,"title":["The clonal evolution of metastases from primary serous epithelial ovarian cancers"],"prefix":"10.1002","volume":"124","author":[{"given":"Lalarukh","family":"Khalique","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ayse","family":"Ayhan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John C.","family":"Whittaker","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naveena","family":"Singh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ian J.","family":"Jacobs","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simon A.","family":"Gayther","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susan J.","family":"Ramus","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2009,1,27]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/0092-8674(90)90186-I"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1535-6108(03)00167-3"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1158\/1078-0432.CCR-06-0659"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/path.2112"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1038\/bjc.1995.510"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1093\/jnci\/djh272"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1331931100"},{"key":"e_1_2_6_9_2","first-page":"1597","article-title":"Genetic heterogeneity and clonal evolution underlying development of asynchronous metastasis in human breast cancer","volume":"57","author":"Kuukasjarvi T","year":"1997","journal-title":"Cancer Res"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9440(10)65120-6"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1038\/sj.bjc.6690760"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1038\/418823a"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0530291100"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1038\/ng1941"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1470-2045(02)00820-3"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1158\/1078-0432.CCR-08-0373"},{"key":"e_1_2_6_17_2","first-page":"3331","article-title":"Semiautomated assessment of loss of heterozygosity and replication error in tumors","volume":"56","author":"Canzian F","year":"1996","journal-title":"Cancer Res"},{"key":"e_1_2_6_18_2","volume-title":"PHYLIP (Phylogeny Inference Package) version 3.6.
