VII. To create a biospecimen repository including plasma, serum and CellSearch cassettes containing circulating tumor cells (CTC) for evaluating determinants of late relapse, including candidate biomarkers reflecting occult tumor burden (e.g., CTCs and plasma tumor deoxyribonucleic acid [DNA]) and host factors (e.g., estrogen, insulin-insulin-like growth factor [IGF] axis, inflammation, etc).
