Brief Summary

Exploring the therapeutic effect of neoadjuvant chemotherapy combined with PD-1 inhibitor camrelizumab on advanced stage III-IV endometrial cancer

Detailed Description

Conduct domestic multicenter, prospective phase II single arm clinical trials to answer the following questions：

1. Evaluate the impact of neoadjuvant chemotherapy combined with camrelizumab on the remission rate, surgical complications, and surgical resection rate of advanced stage III-IV endometrial cancer;

2. Evaluate the effect of of neoadjuvant chemotherapy combined with camrelizumab on the survival of patients with advanced III-IV endometrial cancer;

3. Exploring the changes in tumor local immune related factors and cells before and after neoadjuvant chemotherapy and camrelizumab use, as well as the responsiveness of different molecular subtypes of endometrial cancer to neoadjuvant therapy, and screen for biological indicators that predict the effectiveness of camrelizumab.

Patients with advanced endometrial cancer were enrolled for 2-3 cycles of neoadjuvant chemotherapy in combination with camrelizumab, with imaging to assess efficacy; intermittent subtractive surgery (transabdominal hysterectomy + bilateral adnexectomies + pelvic lymph node dissection + pelvic and abdominal tumors resections +/- para-abdominal aortic lymph node dissection) was performed in patients with complete remissions (CR)/partial remissions (PR), and continued with 3-4 cycles of neoadjuvant chemotherapy in combination with camrelizumab.
