Trial Information

Wide Excision Alone for DCIS-Grades 1 and 2

- Treatment consists of wide excision that will remove the area of DCIS and a minimum of
1cm histologically negative margin of breast tissue. A post-excision mammogram will be
performed to verify complete excision of all calcifications.

- Follow-up consists of physical examinations at least every 6 months by the surgeon or
radiation oncologist. Mammograms of the affected breast will be obtained every 6
months for 5 years and then annually. Mammograms of the unaffected breast will be
performed annually.

Inclusion Criteria:

- Patients must have high quality mammogram including magnification views of area
containing suspicious calcifications.

- The clinical extent of DCIS must be less than or equal to 2.5cm.
