简要总结
This trial will explore effectiveness and safety using the combination therapy of camrelizumab，apatinib and hyperfractionated radiotherapy in patients with renal cell carcinoma(RCC). Hypofractionation is a technique that delivers higher daily doses of radiation over a shorter period of time.immunotherapy. hyperfractionated radiotherapy, represented by stereotactic body radiation therapy (SBRT), can significantly improve the radiotherapy sensitivity of RCC. This trial will also observe whether SBRT can bring about immune effects and explore the group and individual indicators that affect the treatment effect of RCC.
详细描述
This trial is a prospective, single-center, observational clinical trial evaluating the combination therapy of camrelizumab，apatinib and hyperfractionated radiotherapy in patients with renal cell carcinoma(RCC). All enrolled patients will receive the following treatments: camrelizumab 200mg every 2 weeks for 1 years combined with apatinib 250mg everyday until disease progression (as determined by RECIST 1.1), intolerance, or patient/physician decision to stop treatment. One week following completion of the second immunotherapy, hypofractionated radiotherapy with marginal dose of 50Gy/2Gy/25f and tumor center dose of local hyperfraction increase 24-32Gy/8-12Gy/3-4f will be performed 3-5 times. The routine radiotherapy will be started at the same time as the third immunotherapy and 25 times routine radiotherapy will be completed before the fifth or sixth immunotherapy.
During treatment participants will be assessed for curative effects and the occurrence of adverse events. Following treatment, participants will be assessed at a clinic visit every 3 months to collect survival information and follow-up treatment information. The planned sample size is 30 study participants.
