Neoadjuvant Anti-PD-L1 (Durvalumab/MEDI4736) Plus Anti-CTLA-4 (Tremelimumab) and Radiation for High Risk Soft-Tissue Sarcoma
Chemotherapy is controversial for soft tissue sarcoma that has not yet metastasized. Surgery and radiation are effective for local control, but there are no highly effective interventions to prevent metastatic spread of soft tissue sarcoma. Immunotherapy has shown promise in other types of cancer. Combining two types of immunotherapy agents with preoperative radiation may help the immune system recognize the sarcoma and stimulate an anti-tumor immune response.
