cervical cancer staging

Question 1

Stage 0 CC

Answer 1

CIS

Question 2

Stage I CC: carcinoma has grown deeper into the cervix, but has not spread beyond it

Answer 2

• IA: diagnosed only by microscopy, with deepest invasion ≤5 mm and the largest extension ≤7 mm
• IA-1: invasion of ≤3.0 mm in depth and extension of ≤7.0 mm
• IA-2: invasion of >3.0 mm and not >5.0 mm with an extension of not >7.0 mm
• IB Clinically visible lesions limited to the cervix
• IB-1 Clinically visible lesion <4.0 cm in greatest dimension
• IB-2 Clinically visible lesion >4.0 cm in greatest dimension

Question 3

Stage II cc

Cervical carcinoma invades beyond the uterus, but not to the pelvic wall or to the lower third of the vagina

Answer 3

• IIA Without parametrial invasion
• IIA-1 Clinically visible lesion <4.0 cm in greatest dimension
• IIA-2 Clinically visible lesion >4.0 cm in greatest dimension
• IIB With obvious parametrial invasion

Question 4

Stage III . CC

The tumour extends to the pelvic wall and/or involves lower third of the vagina and/or causes hydronephrosis or non-functioning kidney

Answer 4

IIIA Tumour involves lower third of the vagina, with no extension to the pelvic wall

IIIB Extension to the pelvic wall and/or hydronephrosis or non-functioning kidney

Question 5

Stage IV CC

The carcinoma has extended beyond the true pelvis or has involved (biopsy proven) the mucosa of the bladder or rectum.

Answer 5

• IVA Spread of the growth to adjacent organs (bladder or rectum)
• IVB Spread to distant organs (brain and bone)
