RT Journal Article SR Electronic T1 Difference in Practice Patterns in the Management of Endometrial Cancer: A Survey of the Members of 4 East Asian Gynecologic Oncology Groups JF International Journal of Gynecologic Cancer JO Int J Gynecol Cancer FD BMJ Publishing Group Ltd SP 1888 OP 1894 DO 10.1097/IGC.0000000000001078 VO 27 IS 9 A1 Lee, Jung-Yun A1 Kim, Jae Weon A1 Lee, Taek Sang A1 Zang, Rongyu A1 Chen, Xiaojun A1 Yang, Jiaxin A1 Wang, Kung-Liahng A1 Sugiyama, Toru YR 2017 UL http://ijgc.bmj.com/content/27/9/1888.abstract AB Objective The aim of this article was to identify current practice patterns of care in the surgical and adjuvant management of endometrial cancer in East Asia (Korea, Japan, China, and Taiwan)Methods A validated 20-item questionnaire on surgical and adjuvant procedures for endometrial cancer was sent to active members of the Gynecologic Oncology Group from 4 East Asian countries. Data were collected using an Internet survey database.Results A total of 376 members from Korea (n = 108), Japan (n = 140), China (n = 51), and Taiwan (n = 77) responded to the survey. With respect to early-stage endometrial cancer, laparotomy (57.7%) was the most preferred mode of surgery in Japan, whereas laparoscopy was the most common in the remaining 3 countries. For patients with presumed stage IA/G1 disease, approximately 65% of respondents favored systematic lymphadenectomy. For patients with presumed stage IB disease, most respondents stated that systematic lymphadenectomy should be performed (92.6% for stage IBG1, 95.8% for stage IBG3). Meanwhile, the extents of lymphadenectomy differed among countries (P < 0.001). Considerable agreement was noted between countries regarding indications for adjuvant therapy for stage IIIA or IIIC1 disease, whereas the preferred options for adjuvant therapy varied according to country (P < 0.001). Specifically, chemotherapy was the most common selection option in Japan, whereas concurrent chemoradiotherapy was preferred in the other countries.Conclusions Considerable agreement was identified with respect to the necessity for lymphadenectomy for surgical staging and the indications for adjuvant therapy. However, extents of surgery and preferred adjuvant treatment options for endometrial cancer varied widely between countries.
