a Five-year overall survival (OS) rate for women 18–40 years old with stage-I epithelial ovarian cancer (EOC). The 5-year OS rate is 92%. Patients at risk are shown under the curve. b Five-year overall survival (OS) rates for women 18–40 years old treated for epithelial ovarian cancer (EOC) with fertility-sparing surgery (FSS) vs. radical surgery (RS). The 5-year OS rate is 97% for FSS and 89% for RS. Patients at risk are shown under the curve. c Five-year progression-free survival (PFS) rate for women 18–40 years old with epithelial ovarian cancer (EOC). The 5-year PFS rate is 88%. Patients at risk are shown under the curve. d Five-year progression-free survival (PFS) rates for women 18–40 years old treated for epithelial ovarian cancer (EOC) with FSS vs. RS. The 5-year PFS rate for FSS is 93 and 82% for RS. Patients at risk are shown under the curve. e Five-year progression-free survival (PFS) rates for women 18–40 years old treated with FSS vs. RS for FIGO stages IA and IC epithelial ovarian cancer (EOC). The 5-year PFS rates are as follows: FSS IA–93%; FSS IC–93%; RS IA–82%; and RS IC–82%. Patients at risk are shown under the curve
