- Stage 0 – full-thickness involvement of the epithelium without invasion into the stroma (carcinoma in situ)
- Stage I – limited to the cervix
- IA – diagnosed only by microscopy; no visible lesions
- IA1 – stromal invasion less than 3 mm in depth and 7 mm or less in horizontal spread
- IA2 – stromal invasion between 3 and 5 mm with horizontal spread of 7 mm or less
- IA1 – stromal invasion less than 3 mm in depth and 7 mm or less in horizontal spread
- IB – visible lesion or a microscopic lesion with more than 5 mm of depth or horizontal spread of more than 7 mm
- IB1 – visible lesion 4 cm or less in greatest dimension
- IB2 – visible lesion more than 4 cm
- IB1 – visible lesion 4 cm or less in greatest dimension
- Stage II – invades beyond cervix
- IIA – without parametrial invasion, but involve upper 2/3 of vagina
- IIB – with parametrial invasion
- IIA – without parametrial invasion, but involve upper 2/3 of vagina
- Stage III – extends to pelvic wall or lower third of the vagina
- IIIA – involves lower third of vagina
- IIIB – extends to pelvic wall and/or causes hydronephrosis or non-functioning kidney
- IIIA – involves lower third of vagina
Stage IV-Distant spread
- IVA – invades mucosa of bladder or rectum and/or extends beyond true pelvis
- IVB – distant metastasis
Key Points:4stages, each having two subdivisions A and B.No mention of LN status,Ascites.
Treatment
Tumour <5mm-Conization(to preserve fertility)or hysterectomy
Invasive lesions not extending to abdominal viscera or distal vagina-Hysterectomy+Chemotherapy+Radiotherapy
Recurrent disease- Radiotherapy.
