Objective This study aimed to investigate current clinical management of leiomyosarcoma (LMS) in Korea.

Materials and Methods We conducted a Web-based survey among members of the Korean Gynecologic Oncology Group regarding their treatment of LMS.

Results In total, 77 (27.8%) of 277 members responded to the survey. For surgical treatment of stage I LMS, 26.8% indicated total hysterectomy only and 16.9% indicated total hysterectomy with bilateral salpingo-oophorectomy. Also, lymph node dissection was indicated by 54.9% of respondents, whereas 46.5% stated that bilateral salpingo-oophorectomy could be omitted in young patients. More than half (57.7%) of the respondents recommended against adjuvant treatment. For stage I LMS diagnosed after morcellation, 79.2% of the respondents recommended lymph node dissection and 56.4% recommended adjuvant therapy. As for advanced-stage LMS, in cases of complete resection, adjuvant chemotherapy was preferred by 63.1%. For incomplete resection, combined radiotherapy/chemotherapy was the most preferred adjuvant therapy (63.1%).

Conclusions Among Korean Gynecologic Oncology Group members, there are many discrepancies in the clinical management of LMS. A large-scale prospective study to establish treatment guidelines is needed.
