For every positive woman an effort was made to choose 3 HBsAg-negative comparison women, matched for profession (prostitutes or other), age (+2 years), and social class; however, in 5 instances matched triplets (rather than quadruplets) were formed. Among the 40 HBsAg-positive women 9 were AFP positive (23%), whereas among the 115 HBsAg-negative women 13 were AFP positive (11%). A matched analysis indicates that the difference is marginally significant (one-tailed p = 0.03). This finding is compatible with the view that the induction of AFP synthesis in apparently healthy HBsAg-positive individuals may be related with the oncogenic potential of the hepatitis B virus.<\/jats:p>","DOI":"10.1159\/000225818","type":"journal-article","created":{"date-parts":[[2009,6,12]],"date-time":"2009-06-12T10:29:57Z","timestamp":1244802597000},"page":"176-179","source":"Crossref","is-referenced-by-count":2,"title":["Hepatitis B Surface Antigen and Alphafetoprotein Levels in the Serum of Healthy Women"],"prefix":"10.1159","author":[{"given":"Evangelia","family":"Kaklamani","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhao","family":"Zhong-Tang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dimitrios","family":"Trichopoulos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ivonni","family":"Koumantaki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Athina","family":"Kyriakidou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,6,11]]},"container-title":["Oncology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/225818","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000225818","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T23:23:51Z","timestamp":1777677831000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000225818"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,6,11]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000225818","archive":["Portico"],"relation":{},"ISSN":["0030-2414","1423-0232"],"issn-type":[{"value":"0030-2414","type":"print"},{"value":"1423-0232","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,6,11]]}}}
