What are the Treatment Options for Patients Diagnosed with DCIS?

I’ve recently been diagnosed with DCIS; what are my treatment options?

Treatment Options for Patients Diagnosed with DCISOnce you’ve been diagnosed with ductal carcinoma in situ, or DCIS, your doctor will discuss potential treatment options with you. Often, these include lumpectomy or conservative breast surgery, says Dr. Rick Baehner, Director of Pathology at Genomic Health. Following lumpectomy, the decision will need to be made regarding whether or not radiotherapy will be necessary. For larger incidences of DCIS, or DCIS that would be difficult to remove, mastectomy is an additional option; then, the treatment decision must be made on whether or not to add endocrine therapy. Prior to making these decisions, it will need to be determined whether or not the DCIS is ER positive. For women who receive a lumpectomy or breast conserving surgery for their DCIS, the Oncotype DX test can help assign a DCIS score, which assesses the individual tumor tissue to assign a recurrence score. This recurrence score can help physicians and patients decide whether or not additional therapies, such as chemotherapy, will be beneficial or not.

Watch as Dr. Baehner details treatment options for patients diagnosed with DCIS.

Rick Baehner, M.D.: Let me tell you about the treatment options for patients with newly diagnosed DCIS.

Lumpectomy or conservative breast surgery is the most common therapy. Following lumpectomy, a treatment decision needs to be made about whether or not to add radiotherapy. Then, for large DCIS or DCIS that would be difficult to remove, mastectomy is another option. There is also a decision about whether or not to give endocrine therapy. This is made after assessing whether or not the DCIS is ER positive. Now the DCIS score is a test for women who undergo lumpectomy or breast conserving surgery. It is not a test for patients who receive mastectomy for their DCIS.
