Gynecologic cancer clinical practice guidelines in Korea and current issues.

The most common gynecologic cancers in the world are ovarian cancer, endometrial cancer, and cervical cancer; these are also the most prevalent gynecologic cancers in Korea. According to the Korean Central Cancer Registry, these three types of cancer accounted for 6.7% of Korea’s cancer mortality in 2017, of which cervical cancer and ovarian cancer were the eighth and ninth most common causes of death, respectively [1]. From 1999 to 2017, the cumulative total number of patients with these three types of cancer was 134,863. The incidence of ovarian cancer and endometrial cancer is increasing annually, whereas that of cervical cancer is decreasing because of the National Cervical Cancer screening program and prophylactic human papillomavirus (HPV) vaccination [2]. Clinical guidelines for gynecologic cancers have been developed and published by all national groups and regularly updated based on recent evidence. In Korea, the Korean Society of Gynecologic Oncology practice guidelines are published periodically; here, we would like to introduce the latest version of these gynecologic cancer treatment guidelines briefly, along with recent findings.
