Detailed Summary

This phase II trial studies how well atezolizumab works in treating patients with chondrosarcoma or clear cell sarcoma that is newly diagnosed, cannot be removed by surgery (unresectable), or has spread to other places in the body (metastatic). Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
