DCIS Consortium

By building a rich comprehensive cohort of retrospective cases of ductal carcinoma in situ (DCIS) with matched DCIS or invasive recurrence and corresponding registry containing clinical, pathological, digital imaging, molecular markers and long-term >10 year follow-up data together with biospecimens, the collaborative team will improve understanding of the biology of DCIS. Within the consortium, the team will procure tissue blocks from recurrent cases with primary DCIS for a defined cohort to molecularly characterize both the index and recurrent lesions.
