However, cases in which these features are absent have been occasionally reported in Japan. Here, clinical and biological features of 13 T-PLL cases, diagnosed between 1992 and 2009 in the Tohoku region of Japan, were compared with three Western series. Median age was 64 (range 40-78) years old, and the male to female ratio (12:1) was higher than that of the Western series (P < 0.04). Presented manifestations were similar to those of Western cases, but central nervous system involvement, which is rare in Western cases, was observed in 3 of 13 cases (23 %) (P < 0.04). Immunophenotypic patterns were similar to those of Western cases, but HLA-DR was positive in 6 of 9 cases (67 %), which is distinct from Western cases (0-9 %) (P < 0.002). By chromosome analyses, 14q11 abnormality and trisomy 8q, which are common among Western cases (70-80 %), were not observed in any cases (P < 0.002). Morphologically, seven were classified as typical type, five as a small-cell variant, and one as a cerebriform variant. Seven cases experienced an aggressive course, whereas six experienced an indolent course over a median follow-up of 50 months. In contrast to Western cases, clinical courses were closely correlated with morphological types; 86 % of typical types were aggressive, whereas 83 % of small-cell types were indolent (P = 0.025). On the basis of these observations, together with previous Japanese cases in the literature, we propose that Japanese cases of T-PLL may constitute a variant.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/s12185-012-1077-y","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0925-5710","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kameoka, Junichi"}],"nameIdentifiers":[{"nameIdentifier":"465075","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takahashi, Naoto"}],"nameIdentifiers":[{"nameIdentifier":"465076","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Noji, Hideyoshi"}],"nameIdentifiers":[{"nameIdentifier":"465077","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Murai, Katzunori"}],"nameIdentifiers":[{"nameIdentifier":"465078","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tajima, Katsushi"}],"nameIdentifiers":[{"nameIdentifier":"465079","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kameoka, Yoshihio"}],"nameIdentifiers":[{"nameIdentifier":"465080","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sato, Shinji"}],"nameIdentifiers":[{"nameIdentifier":"465081","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shichishima, Tsutomu"}],"nameIdentifiers":[{"nameIdentifier":"465082","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ishida, Yoji"}],"nameIdentifiers":[{"nameIdentifier":"465083","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Harigae, Hideo"}],"nameIdentifiers":[{"nameIdentifier":"465084","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sawada, Kenichi"}],"nameIdentifiers":[{"nameIdentifier":"465085","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田嶋 克史","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"465086","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"T-cell prolymphocytic leukemia in Japan: is it a variant?","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"T-cell prolymphocytic leukemia in Japan: is it a variant?"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-12-02"},"publish_date":"2013-12-02","publish_status":"0","recid":"46652","relation_version_is_last":true,"title":["T-cell prolymphocytic leukemia in Japan: is it a variant?"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:49:13.610892+00:00"}
