Although chemotherapy and endocrine therapy have improved the prognosis, they can induce chemotherapy-related amenorrhoea. Some guidelines recommend fertility preservation before breast cancer treatment. This study aimed to assess whether fertility preservation affects the timing of breast cancer treatment and oncological outcomes. Methods: We performed a retrospective study of 249 patients under 45 years of age diagnosed with breast cancer between 2010 and 2021 at our institution. We compared the interval from breast cancer diagnosis to the start of breast cancer treatment and the prognosis among patients who did and did not undergo fertility preservation. Results: Twenty-two patients (8.8%) underwent fertility preservation (FP group) and 227 (91.2%) did not undergo fertility preservation (non-FP group). The intervals from breast cancer diagnosis to initial treatment were 41.1 days in the FP group and 45.2 days in the non-FP group (p = 0.87). Cancer recurrence was noted in 5 patients in the FP group and in 22 in the non-FP group. Two patients in the FP group and eight in the non-FP group died. There were no differences in relapse-free or overall survival between the two groups (p = 0.07/0.19). Conclusions: There were no differences in the interval from cancer diagnosis to the start of treatment or the oncological outcomes based on whether patients underwent fertility preservation. Fertility preservation should be considered before breast cancer treatment in young cancer patients.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.14994/tohojmed.2022-019","subitem_identifier_reg_type":"JaLC"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Medical Society of Toho University","subitem_publisher_language":"en"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"21891990","subitem_source_identifier_type":"PISSN"}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1726887171532":{"attribute_name":"レコードID","attribute_value_mlt":[{"subitem_description":"TD06064078","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_1726887212651":{"attribute_name":"資源タイプ(ローカル)","attribute_value_mlt":[{"subitem_description":"TOHO University Scholarly Publication","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_1726887247123":{"attribute_name":"出版地","attribute_value_mlt":[{"subitem_description":"Tokyo","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Division of Breast and Endocrine Surgery, Department of Surgery, Toho University School of Medicine","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Saito, Fumi","creatorNameLang":"en"}],"creatorType":"Author"},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Division of Breast and Endocrine Surgery, Department of Surgery, Toho University School of Medicine","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Sumazaki, Makoto","creatorNameLang":"en"}],"creatorType":"Author"},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Division of Breast and Endocrine Surgery, Department of Surgery, Toho University School of Medicine","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Ogata, Hideaki","creatorNameLang":"en"}],"creatorType":"Author"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","displaytype":"detail","filename":"td06064078.pdf","filesize":[{"value":"213.2 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://toho.repo.nii.ac.jp/record/2003000/files/td06064078.pdf"},"version_id":"96387919-f4b1-4392-8e19-bbb36c0129c9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"fertility preservation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"adolescent and young adult","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"breast cancer","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"chemotherapy","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"amenorrhea","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"Study on the Effects of Fertility Preservation on the Timing of Breast Cancer Treatment and Oncological Outcomes","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Study on the Effects of Fertility Preservation on the Timing of Breast Cancer Treatment and Oncological Outcomes","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"82","path":["1727661012447"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-01"},"publish_date":"2023-03-01","publish_status":"0","recid":"2003000","relation_version_is_last":true,"title":["Study on the Effects of Fertility Preservation on the Timing of Breast Cancer Treatment and Oncological Outcomes"],"weko_creator_id":"82","weko_shared_id":-1},"updated":"2024-12-06T08:07:51.181066+00:00"}
