This has led to the abandonment of conventional approaches to primary site assignment, and the recognition that most such synchronous neoplasms are clonally related single tumours with metastatic spread, rather than independent primary tumours. These discoveries have implications for diagnostic practice, analogous to the gradual change over the last few decades in our approach to mucinous neoplasms of the ovary metastatic from the gastrointestinal tract. In this review, we first examine the routes of metastasis to the ovary, and then discuss the diagnostic and clinical implications of concurrent ovarian carcinomas arising in combination with endometrial, endocervical and tubal carcinomas. It is proposed that cases of primary low\u2010grade endometrioid endometrial carcinoma with a secondary unilateral ovarian tumour, both with indolent characteristics, may be classified as \u2018FIGO stage IIIA\u2010simulating independent primary tumours\u2019, with a comment that conservative management would be appropriate. It should be recognised that human papillomavirus\u2010associated endocervical adenocarcinomas may result in synchronous or metachronous ovarian metastases that appear to be unrelated to the primary tumour, and that these may be managed conservatively in the absence of other sites of disease. In cases of tubo\u2010ovarian high\u2010grade serous carcinoma, tubal intraepithelial or contralateral adnexal involvement should count as a pelvic disease site for staging purposes.<\/jats:p>","DOI":"10.1111\/his.13985","type":"journal-article","created":{"date-parts":[[2019,12,17]],"date-time":"2019-12-17T13:12:05Z","timestamp":1576588325000},"page":"37-51","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":55,"title":["Metastases to the ovary arising from endometrial, cervical and fallopian tube cancer: recent advances"],"prefix":"10.1111","volume":"76","author":[{"given":"Laura","family":"Casey","sequence":"first","affiliation":[{"name":"Department of Cellular Pathology Barts Health NHS Trust London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1782-1967","authenticated-orcid":false,"given":"Naveena","family":"Singh","sequence":"additional","affiliation":[{"name":"Department of Cellular Pathology Barts Health NHS Trust London UK"},{"name":"Blizard Institute of Core Pathology Queen Mary University of London London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,12,17]]},"reference":[{"key":"e_1_2_18_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9440(10)65628-3"},{"key":"e_1_2_18_3_1","first-page":"2541","article-title":"Temporal progression of metastasis in lung: cell survival, dormancy, and location dependence of metastatic inefficiency","volume":"60","author":"Cameron MD","year":"2000","journal-title":"Cancer Res."},{"key":"e_1_2_18_4_1","doi-asserted-by":"publisher","DOI":"10.1038\/nrc865"},{"key":"e_1_2_18_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ccr.2007.12.003"},{"key":"e_1_2_18_6_1","doi-asserted-by":"publisher","DOI":"10.1038\/nrclinonc.2011.158"},{"key":"e_1_2_18_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ccr.2013.04.017"},{"key":"e_1_2_18_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cell.2011.11.025"},{"key":"e_1_2_18_9_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature09515"},{"key":"e_1_2_18_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ccr.2013.09.007"},{"key":"e_1_2_18_11_1","doi-asserted-by":"publisher","DOI":"10.1101\/gad.277681.116"},{"key":"e_1_2_18_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cell.2011.09.024"},{"key":"e_1_2_18_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cell.2011.02.013"},{"key":"e_1_2_18_14_1","volume-title":"Cancer invasion and metastasis: molecular and cellular perspective","year":"2013"},{"key":"e_1_2_18_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cell.2009.11.007"},{"key":"e_1_2_18_16_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.1234850"},{"key":"e_1_2_18_17_1","doi-asserted-by":"publisher","DOI":"10.1038\/nm.2401"},{"key":"e_1_2_18_18_1","doi-asserted-by":"publisher","DOI":"10.1038\/nrc3265"},{"key":"e_1_2_18_19_1","doi-asserted-by":"publisher","DOI":"10.1101\/gad.225334.113"},{"key":"e_1_2_18_20_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9258(19)49853-0"},{"key":"e_1_2_18_21_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.semcancer.2009.05.003"},{"key":"e_1_2_18_22_1","doi-asserted-by":"publisher","DOI":"10.1038\/nrc1093"},{"key":"e_1_2_18_23_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-0030-1253454"},{"key":"e_1_2_18_24_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.gde.2004.12.005"},{"key":"e_1_2_18_25_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejca.2009.04.007"},{"key":"e_1_2_18_26_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0092-8674(00)80108-7"},{"key":"e_1_2_18_27_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1470-2045(07)70140-7"},{"key":"e_1_2_18_28_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cell.2006.01.007"},{"key":"e_1_2_18_29_1","first-page":"512","article-title":"Quantitation of cell shedding into efferent blood of mammary adenocarcinoma","volume":"35","author":"Butler TP","year":"1975","journal-title":"Cancer Res."},{"key":"e_1_2_18_30_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.97.26.14608"},{"key":"e_1_2_18_31_1","doi-asserted-by":"publisher","DOI":"10.1038\/nm0603-685"},{"key":"e_1_2_18_32_1","doi-asserted-by":"publisher","DOI":"10.1038\/sj.onc.1210220"},{"key":"e_1_2_18_33_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature03098"},{"key":"e_1_2_18_34_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.281.5381.1317"},{"key":"e_1_2_18_35_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12943-015-0321-5"},{"key":"e_1_2_18_36_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9378(15)30003-X"},{"key":"e_1_2_18_37_1","first-page":"667","article-title":"Retrograde menstruation in women undergoing chronic peritoneal dialysis","volume":"57","author":"Blumenkrantz MJ","year":"1981","journal-title":"Obstet.
