Long-Term Survival Trend of Gynecological Cancer: A Systematic Review of Population-Based Cancer Registration Data.

Abstract

Gynecological cancer significantly affect the health of women. This review aimed to describe the global patterns and trends in the survival of patients with gynecological cancers. We searched PubMed, Embase, Web of Science, SinoMed, and SEER for survival analyses of cancer registration data of cervical, endometrial, and ovarian cancers published between 1980 and 2022. Globally, the highest 5-year observed survival rate for cervical cancer was 76.5% in Anshan, Liaoning, China (2008-2017). The 5-year observed survival rates of endometrial and ovarian cancers were higher in Finland (1995-1999, 82.5%) and Singapore (1988-1992, 62.0%). The 5-year relative survival rate of cervical cancer patients was higher in Haining, Zhejiang, China (2011-2014, 85.8%). Korea ranked first at 89.0% and 64.5% for endometrial and ovarian cancers, respectively. Survival rates have improved for cervical, endometrial, and ovarian cancers. Patients aged ≥ 75 years and those with advanced-stage disease had the worst 5-year survival rates. Survival rates were better for squamous cell carcinoma in cervical cancer, for endometrial carcinoma and mucinous adenocarcinoma in endometrial cancer, and for germ cell and sex-cord stromal tumors in ovarian cancer. Over the past four decades, the survival rates of gynecological cancers have increased globally, with notable increases in cervical and endometrial cancers. Survival rates are higher in developed countries, with a slow-growing trend. Future studies should focus on improving survival, especially in ovarian cancer patients.
