curative surgery. For these tumor stages, primary definitive radiochemotherapy is the treatment of choice. Pretreatment surgical lymph node staging may be performed to exclude para-aortic lymph node metastases and may additionally serve to perform oophoropexy or to reduce the tumor bulk.

Radiotherapy consists of external beam irradiation of the uninvolved pelvic lymphatics and uninvolved parametrial tissue with a dose of up to 45 Gy in 180–200 cGy per fraction and imageguided brachytherapy. The dose delivered by external beam radiotherapy is adjusted to the local tumor extent and metastatic nodal involvement (boost). A larger field of external irradiation is chosen in patients with para-aortic lymph node metastases.

Alternatively, stage IVA cervical cancer with invasion of adjacent pelvic organs can be treated with primary pelvic exenteration. The most common therapies according to stage are summarized in Table 2.

1.9.3\ Treatment of Recurrent Disease

Local tumor recurrence with infiltration of the bladder or rectum but without extension to the pelvic sidewall can be treated by potentially curative pelvic exenteration. With strict patient selection, the 5-year survival rate is 82% (Holtz and Dunton 2002). Various other surgical options are available for removal of recurrent tumor. In patients not having undergone radiotherapy or chemotherapy before, these therapeutic options are available for treating central pelvic ­recurrence. Repeat radiotherapy achieves successful local control with improvement of symptoms in cases of recurrent tumor outside the primary radiation field. Palliative chemotherapy is the final option available to all patients in whom curative surgery or radio(chemo)therapy is no longer possible.

1.9.4\ Treatment of Cervical Cancer During Pregnancy

The diagnosis of cervical cancer in a pregnant woman presents a therapeutic dilemma. CIN lesions or microinvasive cancer (stage IA1) can be treated with conization and cerclage with continuation of the pregnancy. Following delivery, thorough repeat evaluation is performed. In patients with more advanced cervical cancer diagnosed in early pregnancy, hysterectomy with termination of the pregnancy is recommended. Patients in advanced pregnancy have the option of premature delivery by cesarean section with subsequent definitive cancer treatment. Continuation of pregnancy with delay of cancer treatment is advocated only after the patient has been fully informed of the potential risks and counseled about the options available and undergoes close follow-up for evaluation of further tumor development.

1.10\ Prognosis

There is a strong correlation between the prognosis of patients with cervical cancer and stage of disease at diagnosis. Consistently, while the overall 5-year survival rate for patients with cervical cancer is 68%, survival rates vary markedly according to the different clinical stages. The 5-year survival rate is 93% for stage IA cervical carcinoma and 80% for stage IB tumors. In patients with more advanced
