Inclusion Criteria:

• Aged between 18 and 70 years.
• Histologically confirmed adenocarcinoma or squamous cervical carcinomas.
• Chest CT scan and ultrasound must be done prior to surgery as to rule out distant metastasis.

• Signed written informed consent prior to study entry.

Exclusion Criteria:

• Previous radiation or chemotherapy treatment or major pelvic surgery.
• Patients with distant metastasis confirmed by imaging or pathology.
• Other uncured malignant tumors in the past five years, except the cured skin basal cell carcinoma and breast carcinoma in situ.
• Any prior anticancer therapy.
• Unable to tolerate postoperative concurrent chemoradiotherapy.
• Patients with evidence of being allergic to fluorouracil, cisplatin or Endostar.
