What are the 4 Stages of Cervical Cancer?
Stage Ia1 – Tumor invasion </=3.0 mm in depth and </=7.0 mm in horizontal dimention.
Stage Ia2 – Tumor invasion >3.0 mm but </=5.0 mm in depth and </=7.0 mm horizontally.
Stage Ib1 – Tumor is limited to the cervix and size </=4.0 cm
Stage Ib2 – Tumor is limited to the cervix and size >4.0 cm
Stage IIa1 – Tumor extends beyond the cervix and the uterus but not to the parametria and size is </=4.0 cm.
Stage IIa2 – Tumor extends beyond the cervix and the uterus but not to the parametria and tumor size is >4.0 cm.
Stage IIb – Tumor has spread to the parametria.
Stage IIIa – Tumor has spread to the lower third of vagina.
Stage IIIb – Tumor has spread to the pelvic wall and may block the ureter causing hydronephrosis.
STAGE IVA – Tumor has invaded beyond the pelvis into the bladder or the rectum.
STAGE IVB – The cancer cells have spread to distant body parts such as distant lymph nodes, lungs, bones, or liver.
Cervical Cancer Treatment
Stage 0 is precancerous lesion that is treated by LEEP, cold knife technique or total hysterectomy (removal of uterus by surgery).
Hysterectomy is the preferred treatment for stage I disease. Although, in some cases of early stage disease and in patients desiring to retain fertility, radical trachelectomy is also an option. In selected patients unfit for surgery, radiation therapy with/without chemotherapy may be given.
Stage II disease is preferably treated with concurrent chemoradiotherapy. Hysterectomy with/without chemoradiotherapy is an option for early stage disease.
Concurrent chemo radiotherapy is considered in most of the cases of stage III disease.
In case of Stage IV cervical cancer, chemotherapy with/without radiotherapy may be considered depending upon the extent of disease.
