Incidence of cervical, endometrial, and ovarian cancer in Korea, 1999-2010

Objective: To investigate the recent incidence of and trends in cervical, endometrial, and ovarian cancer in Korean females. Methods: Data from the Korea Central Cancer Registry between 1999 and 2010 were analyzed. Age-standardized rates (ASRs) and annual percent changes (APCs) were calculated. Results: The absolute incidence rates of the three major gynecologic cancers increased: 6,394 in 1999 to 7,454 in 2010. The ASR for gynecologic cancer was 23.7 per 100,000 in 1999 and decreased to 21.0 in 2010 (APC, -1.1%; 95% confidence interval [CI], -1.53 to -0.70) due to a definitive decrease in the incidence of cervical cancer (APC, -4.3%). Endometrial cancer has been definitively increasing (APC, 6.9% during 1999-2010), especially in females <30 years old (APC, 11.2%) and in females >= 80 years old (APC, 9.5%). The incidence of ovarian cancer is increasing gradually (APC, 1.5%). Conclusion: ASRs and APC for gynecologic cancers overall are decreasing due to the decrease in the incidence of cervical cancer. However, the incidence of endometrial and ovarian cancer has been increasing.
