RecruitingStudy of Personalized Cancer Therapy to Determine Response and ToxicityThe purpose of this study is to learn more about personalized cancer therapy including response to treatment and side effects. Information about the tests and treatments a person received, or will receive, for their cancer will be collected from medical records to help the researchers determine whether or not patients respond better when their physicians choose to treat them according to the genetic makeup of their tumor. Optional research tests may be performed on tissue, body cavity fluid, blood or urine provided, discarded biological samples taken during routine care that would normally be disposed of and not saved, or on blood samples collected for this study. These research tests will be used to create a "profile" of the collected specimens which will describe unique characteristics about the genes involved in a person's cancer. The tests will also help researchers look for biomarkers that may help predict how people respond to treatment.
