Study Groups

Adebrelimab Combined With Paclitaxel for Injection,cisplatin and radiotherapy

Adebrelimab : 20 mg/kg, D1, intravenously, 30-60 min, Q3w. Paclitaxel for Injection: 150 mg/m2, D1 Cisplatin: 50 mg/m2, IV, D1, Q3w. Radiotherapy: pelvic dose: 6MV-X, 180cGy/ times 27 times; Brachydose: 192Ir, 700cGy/ time 4 times.

Group Type: EXPERIMENTAL

Adebrelimab

Intervention Type: DRUG

The medication regimen for all enrolled patients is as follows, and the dose can be adjusted during treatment due to adverse reactions and other circumstances:

Adebrelimab : 20 mg/kg, D1, intravenously, 30-60 min, Q3w. Paclitaxel for Injection: 150 mg/m2, D1 Cisplatin: 50 mg/m2, IV, D1, Q3w. Radiotherapy: pelvic dose: 6MV-X, 180cGy/ times 27 times; Brachydose: 192Ir, 700cGy/ time 4 times.

First of all, after 2 cycles of concurrent chemoradiotherapy, the sequential chemotherapy combined with adbalizumab for 2-4 cycles, and the subsequent investigators selected Adbalizumab or other drugs to maintain the treatment according to the patient's situation or the patient's own will until the disease progressed or intolerable toxicity occurred or the subjects voluntarily withdrew from the study.adebrelimab until disease progression or intolerable toxicity or the subject voluntarily withdrew from the study。
