We identified 76 patients (mean age 74.6 years; 34.2% men) from 45 institutions. Mean time to first infusion was 103.9 days from cognitive assessment and 63.1 days from MRI. PET-to-infusion was 30.9 days, whereas cerebrospinal fluid (CSF) sampling-to-infusion was 85.8 days; the post-test interval remained longer after CSF (Bonferroni-adjusted p\u2009=\u20090.015). Although this claims-based snapshot may not represent all practice in Japan, it suggests that the CSF-based pathway can be associated with a longer post-test interval before treatment initiation.<\/jats:p>","DOI":"10.1177\/13872877261443634","type":"journal-article","created":{"date-parts":[[2026,4,21]],"date-time":"2026-04-21T14:08:35Z","timestamp":1776780515000},"page":"1510-1515","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Early adoption of lecanemab in Japan (December 2023\u2013December 2024): Pretreatment diagnostic timelines from the DeSC claims database"],"prefix":"10.1177","volume":"111","author":[{"given":"Saki","family":"Nakashima","sequence":"first","affiliation":[{"name":"The University of Tokyo"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4351-9526","authenticated-orcid":false,"given":"Kenichiro","family":"Sato","sequence":"additional","affiliation":[{"name":"The University of Tokyo Hospital"},{"name":"The University of Tokyo Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshiki","family":"Niimi","sequence":"additional","affiliation":[{"name":"The University of Tokyo Hospital"},{"name":"The University of Tokyo Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shotaro","family":"Aso","sequence":"additional","affiliation":[{"name":"The University of Tokyo"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hideo","family":"Yasunaga","sequence":"additional","affiliation":[{"name":"The University of Tokyo"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wataru","family":"Satake","sequence":"additional","affiliation":[{"name":"The University of Tokyo"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takeshi","family":"Iwatsubo","sequence":"additional","affiliation":[{"name":"The University of Tokyo Hospital"},{"name":"National Institute of Neuroscience, National Center of Neurology and Psychiatry, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,4,21]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.35772\/ghm.2023.01047"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12877-021-02540-z"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(24)01296-0"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa2212948"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1186\/s13195-024-01568-8"},{"key":"e_1_3_3_7_2","unstructured":"Ministry of Health Labour and Welfare (Japan).
