Procurement and Research Evaluation of Human Blood and Tissues for Detection of Occult Malignancies Using the Polymerase Chain Reaction (PCR) and Proteomics

Biospecimen Banking

Patient specimens (archived paraffin-embedded and frozen specimens and blood/body fluid samples) will be accrued from patients at John Wayne Cancer Institute. Compare biomarker expression among normal, benign, primary tumor, and metastatic tumor tissues. Comparisons will be within patients and amongst patients with different levels of cancer disease progression, or normal versus cancer tumors.
