1. Objective:

To compare response rate and survivals of locally advanced stage cervical cancer patients with residual lesions who had CCRT alone to those who had adjuvant chemotherapy after CCRT.

2. Patients:

1. Cervical cancer stage IIb to IVa with a histopathology of squamous cell carcinoma, adenosquamous cell carcinoma, adenocarcinoma
2. Complete CCRT(Radiation Does: A point 85Gy(+/-10%)B50Gy(+/-10%)concurrent paclitaxel and cisplatin once a week for six cycles)
3. MRI is performed within 4 weeks after CCRT and shows residual lesions (non-lymph node10mmlymph node shortest diameter15mm).
4. Methods:

The patients who have residual lesions after CCRT are randomized to arm A by observation or arm B by adjuvant chemotherapy with paclitaxel plus cisplatin every 3 weeks for 3 cycles.
