[Is radical surgery (or parametrectomy) needed in all surgical procedure for early stage cervical cancer?]

Early stage of cervical cancer is defined by disease confined to the cervix and upper vagina (stage IA to IIA). For early stage, no treatment has demonstrated clear superiority. Treatment options for women with early stage include either exclusive radiotherapy, or radical surgery, or brachytherapy before radical surgery. Radical hysterectomy or trachelectomy include the resection of the parametrium. The rational of parametrectomy is to remove occult disease in the parametrium and its removal is the cause of much of the morbidity of the surgery, specially urinary complications. This surgery can be performed by laparascopy with quality of life improvement and less blood loss but urinary morbidity is still important. The question is if it's possible to be less radical and still oncologically safe. Parametrial invasion is rare in patients with small tumours without lymphovascular space involvement and negative pelvic nodes (no poor prognostic factors). Sentinel node negative could be a strong criteria to predict parametrial involvement. This review reports studies exploring the safety of omitting parametrectomy in these low risk patients and the future possibilities to evaluate these new indications.
