A Single-arm, Open-label, Single-center Prospective Study of Fruquintinib Combined With Envafolimab in the Treatment of Advanced or Unresectable Locally Advanced Bone and Soft Tissue Sarcoma
Study Details
Study Description
Brief Summary
Many osteosarcomas are cured with a variety of combined chemotherapy and surgery, but a significant number will still relapse.VEGF promotes an immunosuppressive microenvironment and contributes to immune checkpoint inhibitor resistance in cancer.We aimed to explore the efficacy and safety of fruquintinib combined immunotherapy for bone and soft tissue sarcoma.
