The radiotherapy is an essential method of treatment for these tumours. The impact of technical quality of radiation therapy on survival was recently considered. In this study treatment\u2010related variables are analysed with a special focus on radiotherapy technical factors.<\/jats:p><\/jats:sec><jats:sec><jats:title>Procedure<\/jats:title><jats:p>The population of 158 children with a diagnosis of medulloblastoma had been undergoing postoperative radiotherapy at MCMCC in Warsaw in the period 1983\u20131997. The medical data of these patients were analysed. Simulation films of the whole\u2010brain irradiation fields were retrospectively reviewed at 112 patients. The distance from the field margin to the cribriform plate and to the floor of the temporal fossa was assessed and correlated with supratentorial relapse.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Five\u2010year overall survival (OS) and 5\u2010year disease free survival (DFS) were 46% and 40%, respectively. In multivariate analysis gender (<jats:italic>P<\/jats:italic>\u2009=\u20090.008), neurological status before radiotherapy (<jats:italic>P<\/jats:italic>\u2009=\u20090.029), M\u2010stage (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001) and sequence of craniospinal irradiation (<jats:italic>P<\/jats:italic>\u2009= 0.019) were significant prognostic factors for OS. For DFS significant factors were M\u2010stage (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001) and neurological status (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). The cranial fields were not fully correctly covered at 43% patients. The field incorrectness was correlated with isolated supratentorial failure (<jats:italic>P<\/jats:italic>\u2009=\u20090.049).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our results are similar to those published in literature. M0\u2010stage was the most powerful favourable prognostic factor. Male gender and neurological status before radiation treatment were associated with poor survival. Also protracted radiotherapy and quality of radiation technique may have an impact on the outcome. \u00a9 2003 Wiley\u2010Liss, Inc.<\/jats:p><\/jats:sec>","DOI":"10.1002\/pbc.10401","type":"journal-article","created":{"date-parts":[[2004,1,9]],"date-time":"2004-01-09T09:01:56Z","timestamp":1073638916000},"page":"155-160","source":"Crossref","is-referenced-by-count":18,"title":["Medulloblastoma in childhood: Impact of radiation technique upon the outcome of treatment"],"prefix":"10.1002","volume":"42","author":[{"given":"Marzanna","family":"Chojnacka","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Skowro\u0144ska\u2010Gardas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2003,10,30]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/mpo.2950250303"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(197712)40:6<3123::AID-CNCR2820400656>3.0.CO;2-6"},{"key":"e_1_2_1_4_2","first-page":"80","volume-title":"Paediatric Radiation Oncology: Tumours of the posterior fossa and the spinal canal","author":"Halperin EC","year":"1999"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/0360-3016(86)90318-4"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/0360-3016(90)90533-P"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19920215)69:4<1061::AID-CNCR2820690438>3.0.CO;2-8"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1981.55.1.0043"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/0360-3016(91)90038-6"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0167-8140(00)00155-9"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0142(19990701)86:1<142::AID-CNCR20>3.0.CO;2-Y"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF00819502"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/0360-3016(82)90443-6"},{"key":"e_1_2_1_14_2","doi-asserted-by":"publisher","DOI":"10.1097\/00000421-199602000-00015"},{"key":"e_1_2_1_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/0277-5379(90)90017-N"},{"key":"e_1_2_1_16_2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19821215)50:12<2941::AID-CNCR2820501239>3.0.CO;2-6"},{"key":"e_1_2_1_17_2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19810215)47:4<806::AID-CNCR2820470429>3.0.CO;2-P"},{"key":"e_1_2_1_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0360-3016(99)00369-7"},{"key":"e_1_2_1_19_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0360-3016(99)00368-5"},{"key":"e_1_2_1_20_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0360-3016(96)00569-X"},{"key":"e_1_2_1_21_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF00302092"},{"key":"e_1_2_1_22_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0360-3016(00)01548-0"},{"key":"e_1_2_1_23_2","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.105.1.43"},{"key":"e_1_2_1_24_2","doi-asserted-by":"publisher","DOI":"10.1148\/93.6.1351"},{"key":"e_1_2_1_25_2","doi-asserted-by":"publisher","DOI":"10.1080\/01621459.1958.10501452"},{"key":"e_1_2_1_26_2","doi-asserted-by":"crossref","first-page":"187","DOI":"10.1111\/j.2517-6161.1972.tb00899.x","article-title":"Regression models and life tables (with discussion)","volume":"34","author":"Cox DR","year":"1972","journal-title":"J Roy Stat Soc B"},{"key":"e_1_2_1_27_2","doi-asserted-by":"publisher","DOI":"10.1016\/0360-3016(87)90159-3"},{"key":"e_1_2_1_28_2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19911001)68:7<1600::AID-CNCR2820680722>3.0.CO;2-V"},{"key":"e_1_2_1_29_2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19830115)51:2<312::AID-CNCR2820510225>3.0.CO;2-Y"},{"key":"e_1_2_1_30_2","doi-asserted-by":"publisher","DOI":"10.1016\/0360-3016(92)90940-J"},{"key":"e_1_2_1_31_2","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.1999.17.3.832"},{"key":"e_1_2_1_32_2","doi-asserted-by":"publisher","DOI":"10.1016\/0360-3016(92)91025-I"},{"key":"e_1_2_1_33_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0360-3016(00)00431-4"},{"key":"e_1_2_1_34_2","doi-asserted-by":"publisher","DOI":"10.1002\/cncr.2820690539"},{"key":"e_1_2_1_35_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1096-911X(199912)33:6<572::AID-MPO9>3.0.CO;2-P"},{"key":"e_1_2_1_36_2","first-page":"615","article-title":"Radiotherapy and adjuvant chemotherapy for childhood medulloblastoma.
