Serum samples were analyzed by simultaneous determining of pregnancy-specific beta-1-glycoprotein (SP-1) using enzyme-linked immunosorbent assay (ELISA) and beta subunit of human chorionic gonadotropin (p-hCG) using Serono radioimmunoassay kit. In 2 patients with metastatic gestational trophoblastic disease (MGTD) SP-1 peaks were found during chemotherapy. In patients with MGTD with normalized (3-hCG levels a repeated, temporary elevation of isolated SP-1 levels was observed within some months following chemotherapy. After the last isolated peak of SP-1 the pulmonary metastases disappeared. This phenomenon was interpreted as a consequence of the oncolytic process in the affected tissue. In 1 patient with nonmetastatic choriocarcinoma SP-1 ELISA pseudoreaction was found. To recognize these pseudoreactions, a control plate with nonimmunized rabbit IgG was used, simultaneously with SP-1 determinations.<\/jats:p>","DOI":"10.1159\/000226858","type":"journal-article","created":{"date-parts":[[2009,6,26]],"date-time":"2009-06-26T05:45:23Z","timestamp":1245995123000},"page":"406-409","source":"Crossref","is-referenced-by-count":5,"title":["Elevated Sera Levels of SP-1 Induced by Chemotherapy in Patients with Metastatic Gestational Trophoblastic Diseases"],"prefix":"10.1159","author":[{"given":"P.M.","family":"G\u0151cze","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.N.","family":"Than","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.G.","family":"Szab\u00f2","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"I.F.","family":"Csaba","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.","family":"Bohn","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,6,26]]},"container-title":["Oncology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/226858","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000226858","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T23:33:53Z","timestamp":1777678433000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000226858"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,6,26]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000226858","archive":["Portico"],"relation":{},"ISSN":["0030-2414","1423-0232"],"issn-type":[{"value":"0030-2414","type":"print"},{"value":"1423-0232","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,6,26]]}}}
