Primary outcomePrimary: Overall Survival — 74 percentage of participants
Summary
The purpose of this study is to evaluate whether radiosurgery, along with standard chemotherapy, immunotherapy (the treatment of cancer by modulating the immune system and immune response), or hormonal therapy, affects the quality and length of life. The standard therapy is surgery, radiation therapy, or chemotherapy alone or in any combination. A second purpose of this study is to determine if the levels of a special type of protein (called cytokines) found in the blood are related to the quality of life while on this treatment.
