Objective: To evaluate the insights of the Thai gynecologic oncologists towards ovarian preservation during staging surgery for early-stage endometrial cancer.

Materials and Methods: The Thai Gynecologic Cancer Society (TGCS) conducted a national survey study on the management of gynecologic cancer among Thai gynecologic oncologists who had been in practice for longer than one year. An electronic online questionnaire was opened for a response during August 2nd and October 31st, 2019. This study retrieved and analyzed data about the concept and practice of ovarian preservation during surgery for early-stage endometrial cancer patients.

Results: Among 170 gynecologic oncologists who responded to the questionnaires, 108 respondents (63.5%) considered ovarian preservation during surgical staging for early-stage endometrial cancer. Young age patients (<40 years old) and low-grade tumors were the 2 most common features taken into consideration. No significant differences in hospital setting grade and practice duration of the respondents were associated with the consideration of ovarian preservation.

Conclusion: Nearly two-third of Thai gynecologic oncologists considered ovarian preservation during surgical staging for earlystage endometrial cancer. The most common features taken into consideration were young age and low-grade tumor.
