Cervical cancer - treatment
Radical hysterectomy, radiotherapy and chemoradiation are all radical modalities
Majority of cancers detected in younger women are early stage ? too radical for early disease ? can fertility be conserved

radical trachelectomy for cervical cancer
21www.zohrehyousefi.com
The formal name of this operation is radical vaginal trachelectomy (RVT) and also known as the Dargent operation and radical trachelectomy.
22www.zohrehyousefi.com
Trachelectomies, broadly, can be divided into the simple and radical variants.
23www.zohrehyousefi.com
A simple trachelectomy refers to the removal of the cervix; this can be considered to be a very large conization procedure

Summary Trachelectomy represents
conservative surgical approach for early stage invasive cervical
cancer Likely to increase in popularity Cytology is mainstay of follow-
up Essentially cytological features
are predictable and similar to those after cone biopsy 38www.zohrehyousefi.com
