Recently, novel markers have been identified which are linked to patient prognosis and therapeutic response. Especially the mutation of the enzyme isocitrate dehydrogenase 1 or 2 (\n                    <jats:italic>IDH1\/2<\/jats:italic>\n                    ) gene and the O\n                    <jats:sup>6<\/jats:sup>\n                    -methylguanine-DNA methyltransferase (\n                    <jats:italic>MGMT<\/jats:italic>\n                    ) promoter methylation status seem to be the most important predictors of survival. From 2012 to 2015, 94 Czech patients with primary brain tumours were enrolled into the study. The\n                    <jats:italic>IDH1\/2<\/jats:italic>\n                    mutation was detected by denaturing capillary electrophoresis. The methylation status of the\n                    <jats:italic>MGMT<\/jats:italic>\n                    gene and other 46 genes was revealed by MS-MLPA. In all 94 patients, the clinical data were correlated with molecular markers by Kaplan-Meier analyses and Cox regression model. The\n                    <jats:italic>MGMT<\/jats:italic>\n                    promoter methylation status was established and compared to clinical data. In our study eight different probes were used to elucidate the\n                    <jats:italic>MGMT<\/jats:italic>\n                    methylation status; hypermethylation was proclaimed if four and more probes were positive. This 3 : 5 ratio was tested and confirmed by Kaplan-Meier and Cox analyses. The study confirmed the importance of the\n                    <jats:italic>IDH1\/2<\/jats:italic>\n                    mutation and hypermethylation of the\n                    <jats:italic>MGMT<\/jats:italic>\n                    gene promoter being present in tumour tissue. Both markers are independent positive survival predictors; in the Cox model the\n                    <jats:italic>IDH<\/jats:italic>\n                    hazard ratio was 0.10 and in the case of\n                    <jats:italic>MGMT<\/jats:italic>\n                    methylation it reached 0.32. The methylation analysis of the panel of additional 46 genes did not reveal any other significant epigenetic markers; none of the candidate genes have been confirmed in the Cox regression analyses as an independent prognostic factor.\n                  <\/jats:p>","DOI":"10.14712\/fb2016062050194","type":"journal-article","created":{"date-parts":[[2024,3,24]],"date-time":"2024-03-24T11:25:20Z","timestamp":1711279520000},"page":"194-202","source":"Crossref","is-referenced-by-count":8,"title":["IDH1\/2 Mutation and MGMT Promoter Methylation \u2013 the Relevant Survival Predictors in Czech Patients with Brain Gliomas"],"prefix":"10.14712","volume":"62","author":[{"given":"Filip","family":"Kram\u00e1\u0159","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Min\u00e1rik","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.","family":"Bene\u0161ov\u00e1","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Halkov\u00e1","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.","family":"Netuka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"O.","family":"Brad\u00e1\u010d","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"V.","family":"Bene\u0161","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"5727","published-online":{"date-parts":[[2024,3,24]]},"reference":[{"key":"fb2016062050194_1","doi-asserted-by":"crossref","first-page":"1459","DOI":"10.1093\/neuonc\/nou063","volume":"16","author":"Bauchet","year":"2014","journal-title":"Neuro Oncol."},{"key":"fb2016062050194_2","doi-asserted-by":"crossref","first-page":"337","DOI":"10.1200\/JCO.2012.43.2674","volume":"31","author":"Cairncross","year":"2013","journal-title":"J.
