Study Summary

This phase I/II trial studies pembrolizumab and radiation therapy in treating patients with intermediate or high-grade soft tissue sarcoma. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving pembrolizumab and radiation therapy may work better in treating patients with soft tissue sarcoma.

Primary Outcome

Necrosis greater than or equal to 90% at pathologic assessment at time of surgery

Interventions
