Staging of Cervical Cancer

Question 1

Stage IA

Answer 1

Stage 1 = Cervix only (ignore extension to corpus)
Stage IA = Can only be identified by microscopy. <5mm^a in size.
- IA1 = Up to 3mm in depth
- IA2 = >3mm up to 5mm in depth

Question 2

Stage IB

Answer 2

Stage 1 = Cervix only (ignore extension to corpus)
Stage IB = >5mm invasion, still limited to the cervix
- IB1 = >5mm <2cm
- IB2 = >2cm <4cm
- IB3 = >4cm

Question 3

Stage IIA

Answer 3

Stage 2 = Invasion beyond uterus but spread does not reach lower third of the vagina or pelvic wall
Stage IIA = Involves upper two thirds of vagina only, no parametrial involvement
- IIA1 = <4cm in greatest dimension
- IIA2 = >4cm in greatest dimension

Question 4

Stage IIB

Answer 4

Stage 2 = Invasion beyond uterus but spread does not reach lower third of the vagina or pelvic wall
Stage IIB = parametrial involvement but not up pelvic wall

Question 5

Stage IIIA

Answer 5

Stage 3 = Carcinoma involves lower 3rd of vagina/or extends to pelvic wall/or causes hydronephrosis or non-functioning kidney/ or paraaortic lymph nodes
- IIIA = Carcinoma involves lower 3rd of vagina, not pelvic wall

Question 6

Stage IIIB

Answer 6

Stage 3 = Carcinoma involves lower 3rd of vagina/or extends to pelvic wall/or causes hydronephrosis or non-functioning kidney/ or paraaortic lymph nodes
- IIIB = Carcinoma extends to pelvic wall/ hydronephrosis or non-functioning kidney

Question 7

Stage IIIC

Answer 7

Stage 3 = Carcinoma involves lower 3rd of vagina/or extends to pelvic wall/or causes hydronephrosis or non-functioning kidney/ or paraaortic lymph nodes

• IIIC = involves pelvic/paraaortic lymph nodes (size or extent is irrelevant)
• IIIC1 = Pelvic lymph nodes only
• IIIC2 = Paraaortic lymph nodes

Question 8

Stage IV

Answer 8

Stage 4 = Carcinoma has spread beyond the true pelvis/has involved (biopsy proven) the mucosa of the bladder or rectum

• IVA = Spread to adjacent organs
• IVB = Spread to distance organs
