FIGOluokitus
FIGOluokitus, also known as the International Federation of Gynecology and Obstetrics (FIGO) staging system, is a widely used method for classifying the stage of cervical cancer. It is based on the extent of the disease within the cervix and the parametrium, as well as the presence of lymph node involvement and distant metastases. The system is designed to help clinicians make decisions about treatment and to facilitate communication between healthcare providers.
The FIGO staging system for cervical cancer is as follows:
Stage 0: Carcinoma in situ, limited to the epithelium of the cervix.
Stage IA: Cancer confined to the cervix, with a maximum diameter of 4 cm.
Stage IB: Cancer confined to the cervix, with a diameter greater than 4 cm.
Stage IIA: Cancer confined to the cervix and parametrium, with a maximum diameter of 4 cm.
Stage IIB: Cancer confined to the cervix and parametrium, with a diameter greater than 4 cm.
Stage III: Cancer confined to the cervix, parametrium, and pelvic lymph nodes, with or without vaginal or
Stage IVA: Cancer with distant metastases, but no evidence of pelvic or para-aortic lymph node involvement.
Stage IVB: Cancer with pelvic or para-aortic lymph node involvement and distant metastases.
The FIGO staging system is regularly updated to reflect advances in our understanding of cervical cancer
