Controversies in the management of endometrial cancer: a survey of the Korean Gynecologic Oncology Group.

Objective: To identify current practice patterns for unresolved issues in the surgical and adjuvant management of endometrial cancer in Korea.
Methods: We designed and conducted a survey of all 218 active members of the Korean Gynecologic Oncology Group to try to identify how they would manage various case scenarios for endometrial cancer. Data were collected using an Internet survey database.
Results: A total of 108 members (49.5%) responded to the survey. Laparoscopy (81.6%) was the most commonly used mode of surgery in early-stage endometrial cancer. Of all the respondents, 19.8% stated that lymphadenectomy could be omitted and 21.7% recommended selective lymphadenectomy based on sentinel biopsy or frozen results for patients with presumed stage IA/grade 1 disease. On the other hand, 71.9% of respondents recommended para-aortic lymphadenectomy for patients with presumed stage IB/grade 1 disease and 86.4% recommended this treatment for presumed stage IB/grade 3 disease. The majority of respondents performed adjuvant therapy for stage IB/grade 2 (91.7%), IB/grade 3 (99.0%), and stage II (89.6%). Whole pelvic radiotherapy and vaginal brachytherapy were the most frequently used options among these patients. All respondents administered adjuvant therapy when node metastasis was found, and concurrent chemoradiotherapy (53.2%) was the most preferred option for stage IIIC1 disease.
Conclusion: There is broad variation in both the surgical and adjuvant treatment of endometrial cancer among Korean gynecologic oncologists.
