Rövid összefoglaló (regiszter, angolul)
The goal of this clinical trial is to learn if combining serplulimab (PD-1 inhibitor) with bevacizumab and short-course total neoadjuvant therapy (TNT) works to treat locally advanced mid-to-low rectal cancer in adults. It will also learn about the safety of this combination. The main questions it aims to answer are: Does adding bevacizumab to serplulimab and TNT increase the complete remission rate (cCR + pCR) compared with serplulimab and TNT alone? What medical problems do participants have when receiving these treatments? Researchers will compare: Experimental group: serplulimab + bevacizumab + chemotherapy + short-course radiotherapy Control group: serplulimab + chemotherapy + short-course radiotherapy Participants will: Receive either the experimental or control regimen for about 4-5 months before surgery or a watch-and-wait approach if complete response is achieved Undergo treatment in cycles that include chemotherapy, immunotherapy (and bevacizumab if in the experimental group), and short-course radiotherapy Visit the clinic regularly for check-ups, blood tests, imaging, endoscopy, and to monitor side effects Be followed for up to 5 years after treatment to assess cancer control, organ preservation, and survival outcomes
