About this trial
This study characterizes deoxyribonucleic acid (DNA) and proteomic (protein) changes in both biopsies and tumors removed during surgery of patients who have been diagnosed with aggressive/metastatic (that has spread to other places in the body) cancer in order to identify possible diagnostic markers and potential drugs for treating aggressive tumor types. Proteomic analyses include looking at the proteome, or all the proteins expressed, or made by DNA at a specific moment in time. Studying samples of blood, buccal (cheek), and tissue in the laboratory from patients undergoing surgical resection or biopsy may help doctors learn more about the changes that occur in the proteome, DNA alterations, and identify molecular biomarkers for which therapeutic drugs may exist. Studying the DNA in tumor tissue and in blood may also help researchers see if the tumor has important differences.
