The average dose was 29\u202fGy (range: 10\u201345\u202fGy) and rigid metal needles were used in\u00a011 (24%) and flexible plastic catheters in 34\u00a0cases (76%).

The incidence of local grade\u00a01,\u00a02 and\u00a03 mucositis was 23, 73 and 4%, respectively. As a\u00a0serious (grade\u00a04), late side effect, soft tissue necrosis developed in 3\u00a0cases (7%). In a\u00a0univariate analysis, there was a\u00a0significant correlation between lymphovascular invasion and RC (<jats:italic>p<\/jats:italic>\u202f=\u20090.0118) as well as cervical recurrence and DSS (<jats:italic>p<\/jats:italic>\u00a0&lt; 0.0001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Sole postoperative HDR brachytherapy can be an effective method in case of negative prognostic factors in the treatment of early, resectable tongue tumours. Comparing the results of patients treated with postoperative BT to those who were managed with surgery or BT alone known from the literature, a\u00a0slightly more favourable LC can be achieved with the combination therapy, demonstrating the potential compensating effect of BT on adverse prognostic factors, while the developing severe, grade\u00a04 toxicity rate remains low.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00066-022-01901-w","type":"journal-article","created":{"date-parts":[[2022,2,14]],"date-time":"2022-02-14T08:05:53Z","timestamp":1644825953000},"page":"812-819","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Results of sole postoperative interstitial, high-dose-rate brachytherapy of T1\u20132 tongue tumours"],"prefix":"10.1007","volume":"198","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3261-0271","authenticated-orcid":false,"given":"Zolt\u00e1n","family":"Tak\u00e1csi-Nagy","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u00d6rs","family":"Ferenczi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4672-6910","authenticated-orcid":false,"given":"Tibor","family":"Major","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2530-4302","authenticated-orcid":false,"given":"Hironori","family":"Akiyama","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6428-6536","authenticated-orcid":false,"given":"Georgina","family":"Fr\u00f6hlich","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ferenc","family":"Oberna","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5651-8536","authenticated-orcid":false,"given":"M\u00f3nika","family":"R\u00e9v\u00e9sz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M\u00e1rton","family":"Po\u00f3sz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7245-0762","authenticated-orcid":false,"given":"Csaba","family":"Polg\u00e1r","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2022,2,14]]},"reference":[{"key":"1901_CR1","doi-asserted-by":"publisher","first-page":"3","DOI":"10.1016\/j.bjoms.2019.08.007","volume":"58","author":"S Papadiochou","year":"2020","unstructured":"Papadiochou\u00a0S, Papadiochos\u00a0I, Perisanidis\u00a0C, Papadogeorgakis\u00a0N (2020) Medical practitioners\u2019 educational competence about oral and oropharyngeal carcinoma: a\u00a0systematic review and meta-analysis.
