We conducted a single-center retrospective study on 37 precocious puberty (PP) patients with intracranial germ cell tumors and 25 age-matched prepubertal patients with elevated human chorionic gonadotropin (hCG) levels. Classification of PP was derived from hCG, gonadotropin and sex steroid levels and their changes. Five boys were assigned to GnRH-dependent group (G1). Thirty-one boys and one girl were assigned to GnRH-independent group (G2) with a median hCG of 76.75 (8.29\u20132747) IU\/L. Seven boys and 18 girls were conducted as controls, with a median hCG of 17.12 (2.91\u20131062) IU\/L. Patients in G1 had constant pubertal LH and testosterone levels after tumor complete response. Patients in G2 had hCG levels that decreased simultaneously with testosterone\/estradiol levels, prior to tumor regression. The differences in hCG levels and the gender ratio were significant between G2 and controls (\n                    <jats:italic>P\u2009=\u2009<\/jats:italic>\n                    0.006 and\n                    <jats:italic>P\u2009&lt;\u2009<\/jats:italic>\n                    0.001, separately). Among intracranial germ cell tumor patients with positive hCG, boys with significantly higher hCG levels more easily developed PP. Our results suggest that GnRH-independent PP commonly regresses together with tumor regression. In comparison, results were inconclusive in tying tumor regression to the regression of GnRH-dependent PP.\n                  <\/jats:p>","DOI":"10.1530\/erc-21-0381","type":"journal-article","created":{"date-parts":[[2022,8,8]],"date-time":"2022-08-08T09:43:07Z","timestamp":1659951787000},"page":"581-588","update-policy":"https:\/\/doi.org\/10.1530\/crossmarkpolicy-8","source":"Crossref","is-referenced-by-count":6,"title":["Precocious puberty due to intracranial germ cell tumors: a case\u2013control study"],"prefix":"10.1530","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8795-6544","authenticated-orcid":true,"given":"Han","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Endocrinology, Beijing Tiantan Hospital, Capital Medical University, Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9587-8008","authenticated-orcid":true,"given":"Ming","family":"Ni","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Beijing Tiantan Hospital, Capital Medical University, Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yun","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynaecology, Beijing Tiantan Hospital, Capital Medical University, Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2016-0664","authenticated-orcid":true,"given":"Li-Yong","family":"Zhong","sequence":"additional","affiliation":[{"name":"Department of Endocrinology, Beijing Tiantan Hospital, Capital Medical University, Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"416","reference":[{"key":"bib1","series-title":"Archives of Disease in Childhood","doi-asserted-by":"publisher","first-page":"743","DOI":"10.1136\/adc.58.9.743","article-title":"Human chorionic gonadotrophin secreting pineal germinoma and precocious puberty","volume":"58","author":"Ahmed","year":"1983","unstructured":"Ahmed SRShalet SMPrice DAPearson D1983Human chorionic gonadotrophin secreting pineal germinoma and precocious puberty.
