These patients included all operative survivors (excluding cases with total tumor removal) treated during the 30 years from 1950 to 1979. Median survival time of the irradiated group was greater than 10 years, whereas it was 3.12 years for the nonirradiated (or control) group. The 5- and 10-year survival rates were 88.9% and 76.0% for the irradiated group, and 34.9% and 27.1% for the control group, respectively. Overall comparison, using the Lee-Desu statistical method, revealed that there was a very high statistical significance (at the level of p &lt; 0.0001) in the difference between the survival times of the irradiated and control groups. The influence of the following factors on the effectiveness of radiotherapy was analyzed: age of the patient at the first operation, sex, date of surgery, the extent of tumor removal, the size of the tumor, the composition of the tumor (cystic or solid), whether the tumor was calcified or not, the histological subtype of the tumor, the presence of intracranial hypertension, the grade of visual failure, and the presence or absence of diabetes insipidus, altered mentation, and adiposogenital syndrome. The results indicated that, when total removal of the tumor is impossible, radiotherapy should be administered.<\/jats:p>","DOI":"10.3171\/jns.1985.62.5.0648","type":"journal-article","created":{"date-parts":[[2009,5,8]],"date-time":"2009-05-08T16:15:57Z","timestamp":1241799357000},"page":"648-656","source":"Crossref","is-referenced-by-count":96,"title":["The efficacy of radiotherapy for craniopharyngioma"],"prefix":"10.3171","volume":"62","author":[{"given":"Shinya","family":"Manaka","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akira","family":"Teramoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kintomo","family":"Takakura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Childs Brain","first-page":"57","article-title":"Craniopharyngioma: the controversy regarding radiotherapy.","volume":"6","author":"Amacher","year":"1980"},{"key":"b2","series-title":"J Neurol Neurosurg Psychiatry","doi-asserted-by":"publisher","first-page":"37","DOI":"10.1136\/jnnp.34.1.37","article-title":"Craniopharyngiomas \u2014 a summary of 85 cases.","volume":"34","author":"Bartlett","year":"1971"},{"key":"b3","series-title":"Proc Staff Meet Mayo Clin","first-page":"270","article-title":"Calculation of survival rates for cancer.","volume":"25","author":"Berkson","year":"1950"},{"key":"b4","series-title":"Proc R Soc Med","first-page":"319","article-title":"The role of radiotherapy in the management of chiasmal compression.","volume":"70","author":"Bloom","year":"1977"},{"key":"b5","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"382","DOI":"10.1227\/00006123-198209000-00008","article-title":"Craniopharyngiomas in children.","volume":"11","author":"Carmel","year":"1982"},{"key":"b6","series-title":"AJR","first-page":"162","article-title":"The treatment of hypophyseal stalk tumors by evacuation and irradiation.","volume":"38","author":"Carpenter","year":"1937"},{"key":"b7","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"409","DOI":"10.3171\/jns.1983.59.3.0409","article-title":"Neurological and psychophysiological sequelae following different treatments of craniopharyngioma in children.","volume":"59","author":"Cavazzuti","year":"1983"},{"key":"b8","series-title":"Brain Tumor Registry in Japan.","first-page":"71","volume":"5","author":"The Committee of Brain Tumor Registry in Japan","year":"1984"},{"key":"b9","series-title":"Int J Radiat Oncol Biol Phys","doi-asserted-by":"publisher","first-page":"171","DOI":"10.1016\/0360-3016(83)90094-9","article-title":"Childhood craniopharyngioma: survival, local control, endocrine and neurologic function following radiotherapy.","volume":"9","author":"Danoff","year":"1983"},{"key":"b10","series-title":"Cancer","doi-asserted-by":"publisher","first-page":"1465","DOI":"10.1002\/1097-0142(197106)27:6<1465::AID-CNCR2820270629>3.0.CO;2-7","article-title":"Ultrastructure of a craniopharyngioma.","volume":"27","author":"Ghatak","year":"1971"},{"key":"b11","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"299","DOI":"10.3171\/jns.1972.36.3.0299","article-title":"Craniopharyngiomas in children and adults.","volume":"36","author":"Hoff","year":"1972"},{"key":"b12","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"218","DOI":"10.3171\/jns.1977.47.2.0218","article-title":"Management of craniopharyngioma in children.","volume":"47","author":"Hoffman","year":"1977"},{"key":"b13","series-title":"SPSS Update 7\u20139.
