The data of patients whose treatment with gynecologic malignancies was initiated in 2020 were analyzed retrospectively.

This clinicopathological information was summarized as the patient annual report. The 5\u2010year survival rates of the patients with cervical cancer were 92.3%, 76.2%, 56.5%, and 32.2% for Stages I, II, III, and IV, respectively. The 5\u2010year survival rates for the patients with endometrial cancer were 93.9%, 87.6%, 71.4%, and 29.3% for Stages I, II, III, and IV, respectively. The 5\u2010year survival rates for the patients with ovarian cancer (surface epithelial\u2010stromal tumors) were 91.7%, 80.6%, 50.8%, and 39.7% for Stages I, II, III, and IV, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The annual tumor report is an important survey that provides knowledge on gynecological malignancy trends in Japan.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jog.15767","type":"journal-article","created":{"date-parts":[[2023,8,21]],"date-time":"2023-08-21T14:22:17Z","timestamp":1692627737000},"page":"2584-2592","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Annual report of the Committee on Gynecologic Oncology, the Japan Society of Obstetrics and Gynecology: Annual Patient Report for 2020 and Annual Treatment Report for 2015"],"prefix":"10.1111","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5732-5215","authenticated-orcid":false,"given":"Kiyoshi","family":"Yoshino","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology University of Occupational and Environmental Health  Kitakyusyu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3877-7520","authenticated-orcid":false,"given":"Tomoko","family":"Kurita","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology University of Occupational and Environmental Health  Kitakyusyu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fumiaki","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Department of Information Science Iwate Medical University  Yahaba Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5212-1128","authenticated-orcid":false,"given":"Satoru","family":"Nagase","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Faculty of Medicine Yamagata University  Yamagata Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Board members of the 2022 Committee on Gynecologic Oncology of the Japan Society of Obstetrics and Gynecology","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,8,21]]},"reference":[{"key":"e_1_2_8_2_1","first-page":"2263","article-title":"The patients annual report in 2020","volume":"74","author":"Nagase S","year":"2022","journal-title":"Acta Obst Gynaec Jpn"},{"key":"e_1_2_8_3_1","first-page":"2346","article-title":"The treatment annual report in 2015","volume":"74","author":"Nagase S","year":"2022","journal-title":"Acta Obst Gynaec Jpn"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/jog.15284"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1806395"},{"key":"e_1_2_8_6_1","unstructured":"American Cancer Society.
