A Multi Tumor, Open Phase I Clinical Study on the Progression of First-line Anti-tumor Therapy Using Cardonizumab Combined With Pulsed Low-dose Rate External Irradiation (PLDR)
At present, the treatment methods for recurrent cancers are very limited. The immune checkpoint inhibitors (ICBs) is a promising new directions for recurrent lung cancer/ esophageal cancer / cervical cancer, but the clinical response rate is insufficient. Pulse low-dose rate radiotherapy (PLDR) is a new technology in recent years, which uses continuous pulse low-dose rate irradiation to induce hypersensitivity in tumors, and its clinical safety has been verified. Compared to conventional radiotherapy, PLDR has advantages in protecting the lymphatic system and relieving the immune barrier, but
