The International Federation of Obstetricians and Gynaecologists (FIGO) introduced the following system for the staging of cervical carcinoma:

Histological staging:

  • 0 - CIN III (carcinoma in situ)
  • IA - microinvasive carcinoma

Clinical staging:

  • IB - invasive carcinoma confined to the cervix
  • IIA - invasion into the upper one third of the vagina
  • IIB - extension to the parametria but not to the pelvic side wall
  • IIIA - extension to the lower one third of the vagina
  • IIIB - extension to the pelvic side wall

  • IVA - tumour involving the bladder or rectum
  • IVB - extrapelvic spread, e.g. liver or lung metastases
