Trial Summary

Do I need to stop my current medications for the trial?

The trial does not specify if you need to stop taking your current medications. However, if you are currently receiving chemotherapy, you cannot participate in this trial.

What data supports the effectiveness of the ClearEdge Device treatment for breast cancer surgery?

The ClearEdge Device is designed to help surgeons check if all cancerous tissue has been removed during breast cancer surgery, which is important to prevent cancer from coming back. Similar devices, like MarginProbe, have been shown to reduce the need for additional surgeries by helping ensure all cancerous tissue is removed in the first operation.12345

How does the ClearEdge Device treatment differ from other breast cancer surgery treatments?

The ClearEdge Device is unique because it allows surgeons to check the edges of the removed breast tissue during surgery to ensure all cancerous cells are removed, reducing the need for additional surgeries.12678

What is the purpose of this trial?

This trial is testing whether using the ClearEdge imaging device during breast cancer surgery can help doctors remove all cancerous tissue in one go, reducing the need for repeat surgeries. The device helps surgeons see if the edges of the removed tissue still have cancer cells.

Eligibility Criteria

This trial is for women over 18 with breast DCIS or invasive cancer who are recommended for a lumpectomy. It's not open to those who've had previous surgery or radiation on the same breast, are pregnant or breastfeeding, currently on chemotherapy, have implants, or were in another surgical breast cancer study recently.

Inclusion Criteria

I have been diagnosed with breast cancer and recommended for a lumpectomy.
I have received hormone therapy before surgery for my cancer.
I am genetically female.

Exclusion Criteria

I've had radiation therapy for cancer in the same breast or for another cancer that included breast tissue.
I have not been in any breast cancer studies involving surgery in the last 6 months.
I have had surgery on the same side breast cancer before.

Treatment Details

Interventions

  • ClearEdge Device
Trial Overview The trial is testing if using the ClearEdge device during surgery helps doctors better detect and remove all of the cancer compared to standard care. This could potentially reduce the need for additional surgeries. Participants will be randomly assigned to either use this device or follow usual procedures.
