Cervical cancer may be classified into many subtypes based on FIGO classification.
Newly revised FIGO staging for cervical cancer, included pathological and imaging findings as well as clinical manifestations.
FIGO staging of cancer of the cervix uteri (2018)
|I||The carcinoma is strictly confined to the cervix (extension to the uterine corpus should be disregarded)|
|IA||Invasive carcinoma that can be diagnosed only by microscopy, with maximum depth of invasion <5 mma|
|IA1||Measured stromal invasion <3 mm in depth|
|IA2||Measured stromal invasion ≥3 mm and <5 mm in depth|
|IB||Invasive carcinoma with measured deepest invasion ≥5 mm (greater than Stage IA), lesion limited to the cervix uteri|
|IB1||Invasive carcinoma ≥5 mm depth of stromal invasion, and <2 cm in greatest dimension|
|IB2||Invasive carcinoma ≥2 cm and <4 cm in greatest dimension|
|IB3||Invasive carcinoma ≥4 cm in greatest dimension|
|II||The carcinoma invades beyond the uterus, but has not extended onto the lower third of the vagina or to the pelvic wall|
|IIA||Involvement limited to the upper two‐thirds of the vagina without parametrial involvement|
|IIA1||Invasive carcinoma <4 cm in greatest dimension|
|IIA2||Invasive carcinoma ≥4 cm in greatest dimension|
|IIB||With parametrial involvement but not up to the pelvic wall|
|III||The carcinoma involves the lower third of the vagina and/or extends to the pelvic wall and/or causes hydronephrosis or nonfunctioning kidney and/or involves pelvic and/or para‐aortic lymph nodes|
|IIIA||The carcinoma involves the lower third of the vagina, with no extension to the pelvic wall|
|IIIB||Extension to the pelvic wall and/or hydronephrosis or nonfunctioning kidney (unless known to be due to another cause)|
|IIIC||Involvement of pelvic and/or para‐aortic lymph nodes, irrespective of tumor size and extent (with r and p notations)c|
|IIIC1||Pelvic lymph node metastasis only|
|IIIC2||Para‐aortic lymph node metastasis|
|IV||The carcinoma has extended beyond the true pelvis or has involved (biopsy proven) the mucosa of the bladder or rectum. (A bullous edema, as such, does not permit a case to be allotted to Stage IV)|
|IVA||Spread to adjacent pelvic organs|
|IVB||Spread to distant organs|
