Immune Control of Breast Cancer Tumor Dormancy

Overview

About this study

The Primary Aim of this study is to quantify BDTC in breast cancer patients at different stages of cancer. As part of this aim we will establish the proliferation status of the tumor cells. We will in parallel examine CTC to determine the correlation between BDTC and CTC. The Second Aim is to determine role of tumor associated immune responses in maintaining tumor dormancy. Knowledge gained will provide the rationale for an in depth study of breast cancer tumor dormancy and immune response. Ultimately, the information gained will help us to design of immune intervention strategies that prevent cancer recurrence.
