Patients receiving cancer chemotherapy may respond differently to treatment, by exhibiting a response, deterioration, or the simultaneous occurrence of both. These variations may be attributed to the heterogeneity of the cancer. However, differences in the temporary response to epidermal growth factor receptor‑tyrosine kinase inhibitor (EGFR‑TKI) treatment are rarely observed. If such a phenomenon is observed, it should not affect the evaluation of the therapeutic effect or be considered as an indication for the discontinuation of treatment. We herein report a rare case of a transient increase in carcinomatous pleural fluid as a paradoxical response to osimertinib treatment in a patient with T790M‑mutated lung adenocarcinoma. The primary lesion and pulmonary metastases responded well to therapy. Although this paradoxical response is very rare, of non‑malignant nature, and does not usually require treatment modification of, physicians must acknowledge that it is not a clinically discouraging characteristic when using EGFR‑TKI to treat T790M‑mutated lung adenocarcinoma.","subitem_description_type":"Abstract"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Spandidos Publications"}]},"item_5_relation_10":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"29285395","subitem_relation_type_select":"PMID"}}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.3892/mco.2017.1474","subitem_relation_type_select":"DOI"}}]},"item_5_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2049-9450","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12610944","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"川口, 未央"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐藤, 浩昭"},{"creatorName":"サトウ, ヒロアキ","creatorNameLang":"ja-Kana"},{"creatorName":"SATOH, Hiroaki","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Okauchi, Shinichiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Osawa, Hajime","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Miyazaki, Kunihiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawaguchi, Mio","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-03-06"}],"displaytype":"detail","filename":"MCO_8-1-175.pdf","filesize":[{"value":"496.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"MCO_8-1-175","url":"https://tsukuba.repo.nii.ac.jp/record/49312/files/MCO_8-1-175.pdf"},"version_id":"f715016b-693d-4e60-8715-ba4be2e4f180"}]},"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":"Paradoxical response to osimertinib therapy in a patient with T790M‑mutated lung adenocarcinoma","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Paradoxical response to osimertinib therapy in a patient with T790M‑mutated lung adenocarcinoma"}]},"item_type_id":"5","owner":"1","path":["2610","919","7291"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-06"},"publish_date":"2019-03-06","publish_status":"0","recid":"49312","relation_version_is_last":true,"title":["Paradoxical response to osimertinib therapy in a patient with T790M‑mutated lung adenocarcinoma"],"weko_creator_id":"1","weko_shared_id":5},"updated":"2022-04-27T09:21:52.166052+00:00"}
