简要总结
The goal of this clinical trial is to find a new radioimmunotherapy regimen for advanced malignancies with multiple metastatic after standard treatment failure/drug resistance. The main questions it aims to answer is: the safety and efficacy of the new regimen for advanced multiple metastatic solid tumors standard treatment failure/drug resistance, and explore the impact on immune function. Participants will receive the combination of radiotherapy and immunotherapy.
详细描述
More effective treatment regimens remain to be explored for advanced malignancies with multiple metastatic after standard treatment failure/drug resistance. The combination of radiotherapy and immunotherapy is considered to be a promising therapeutic strategy. Studies showed the efficacy of PRaG (PD-1 inhibitor, Radiotherapy and GM-CSF) treatment and stereotactic radiotherapy (SBRT) combined with low-dose radiotherapy (LDRT) for advanced tumors. Therefore, the investigators designed a new radioimmunotherapy regimen, including SBRT, LDRT , PD-1/PD-L1 inhibitor, and GM-CSF. This study aimed to evaluate the safety and efficacy of the new regimen for advanced multiple metastatic solid tumors standard treatment failure/drug resistance, and explore the impact on immune function.
