Our primary objective is to observe breast tumor recurrence, including ipsilateral, regional, contralateral, and distant recurrences of breast cancer (DCIS or invasive cancer events).Our secondary objective is to assess overall survival in all patients, adverse effects of RT and tamoxifen, and translational studies—including single nucleotide polymorphisms (SNPs), extracellular matrix (ECM)- and immune-related molecules, and mutational analyses of selected genes.
