Inclusion criteria

Inclusion criteria: 1. Age 18-75 years old, gender unlimited; 2. Cervical cancer patients with confirmed pathological diagnosis who have been admitted to our department for radical radiotherapy or postoperative adjuvant radiotherapy; 3. Hematopoietic function and systemic condition of the patient were acceptable (leukocyte > 2.5*109/L, platelet > 50*109/L, bilirubin not exceeding 1.5 times of the upper limit of normal, liver function glutamic-pyruginous transaminase and glutamic-oxalacetic transaminase not exceeding 2.5 times of the upper limit of normal, renal function creatinine not exceeding 1.5 times of the upper limit of normal); 4. No congestive heart failure, unstable angina pectoris, or unstable arrhythmia occurred in the past 6 months; 5. The patients' activity status was evaluated by the Eastern Cooperative Oncology Group (ECOG) score (0-1), functional status was evaluated by Karnofsky (KPS) score (=70), and life expectancy was evaluated (> 12 months); 6. Able to adhere to the programme for the study period; 7. The patient can sign written informed consent.

Exclusion criteria

Exclusion criteria: 1. Pregnant or nursing women. 2. History of malignant tumor, chemotherapy and radiotherapy, except for cured skin cancer; 3.
