About

In recent years, the patients with IB2 and IIA2 stage cervical cancer are still treated with radiotherapy and chemotherapy based treatment, but the radiotherapy will severely damage the function of ovary, cause endocrine dyscrasia and the sexual function of vagina. So we want to study whether neoadjuvant chemotherapy without radiotherapy will achieve the same outcome compared with traditional therapy including radiotherapy. So we randomly divide IB2 and IIA2 stage cervical cancer patients into two groups. The neoadjuvant chemotherapy group will receive two courses of chemotherapy basically composed of platinum, and then undergo surgery, after that, doctors will add more courses of chemotherapy according to the situations of the patients, including whether the patients have the adverse prognostic factors. The control group will undergo surgery directly, and then receive chemotherapy and radiotherapy at the same time. Then we will compare the outcomes of these two groups, and analyze the therapeutic effect, the impact on survival rate and the effect on improving the living quality of patient from two groups. All the outcomes will be fed back to clinical doctors and instruct them to choose better treatment for patients.

774 participants in 2 patient groups

NACT

Experimental group

Description:

The patients will receive 2 courses of platinum based chemotherapy before surgery, 2-3 weeks after each course, doctors will appraise the effect of the chemotherapy. Patients who are sensitive to the treatment will undergo radical hysterectomy and pelvic lymph node dissection 3 weeks after chemotherapy. And 2-3weeks after the surgery, patients will receive adjuvant chemotherapy according to the pathological risk factors.

Treatment:

Procedure: RT+PLND

Drug: NACT

Drug: Adjuvant chemotherapy

PST

Active Comparator group

Description:

The patients in this group will undergo radical hysterectomy and pelvic lymph node dissection directly, and 2-6 weeks after the surgery, they will receive adjuvant chemotherapy according to the pathological risk factors.

Treatment:

Procedure: RT+PLND

Drug: Adjuvant chemotherapy
