Cervical cancer staging standards.

FIGO staging		Tumor node metastasis (TNM)
	The carcinoma in situ was unassessable.	TX
	No evidence of primary cancer was found.	T0
Stage 0	Carcinoma in situ (pre-invasive carcinoma) was found.	Tisn0m0
Stage I	Cervical cancer was confined to the uterus (that spread to the uterus was not considered in staging.).	T1N0M0
I-A	Invasive carcinoma was found under a microscope, including superficial infiltration and any visible lesions.	T1a
I-A1	Interstitial infiltration depth was <3 mm, and horizontal diffusion range was ≤7 mm.	T1a1
I-A2	Interstitial infiltration depth reached 3–5 mm, and horizontal diffusion range was ≤7 mm.	T1a2
I-B	The microscopic lesion was larger than that of stage I-A2, or visible cancer lesions were confined to the cervix.	T1b
I-B1	The maximum diameter of the macroscopic cancer lesions was ≤4 cm.	T1b1
I-B2	The maximum diameter of the macroscopic cancer lesions was >4 cm.	T1b2
Stage II	The cancer spread out of the uterus, but did not reach the pelvic wall or the lower third of the vagina.	T2N0M0
II-A	No parauterine infiltration was found.	T2a
II-B	Parauterine infiltration could be observed.	T2b
