The staging system for choriocarcinoma (usually refers to uterine choriocarcinoma) is the FIGO staging system and is as follows 1:
stage I: disease limited to the uterus
stage II: disease out of the uterus but limited to the female genital tract
stage III: metastasis in the lung with or without involvement of female genital tract
stage IV: all metastasis at other locations
This staging system is much simpler than the system for ovarian cancer staging and endometrial cancer staging.
