Trial summary

This research is studying a new investigative imaging instrument called a nonlinear microscope (NLM). A nonlinear microscope can produce images similar to an ordinary pathologist's microscope, but without first processing tissue to make slides. Read more about this study

About this study

Official title: Real-Time Assessment Of Breast Cancer Lumpectomy Specimen Margins With Nonlinear Microscopy

This research is studying a new investigative imaging instrument called a nonlinear microscope (NLM). A nonlinear microscope can produce images similar to an ordinary pathologist's microscope, but without first processing tissue to make slides. This study will determine if a NLM can be used to evaluate tissue during lumpectomy surgery for breast cancer in order to reduce the probability that standard pathologic examination of the specimen after the end of the operation will find close or positive margins, thus possibly requiring the patient to have additional breast surgery.

Read the detailed description

The purpose of this research study is to improve the treatment of breast cancer and reduce the number of patients who require repeat surgical procedures to completely remove breast malignancy.

In standard procedures, pathologists evaluate tissue samples on a microscope after the surgery is over. The new investigative imaging instrument is an advanced type of microscope that enables evaluation during surgery.

The microscope will not be used directly on the participant or in the operating room, but instead will be used to image tissue immediately after excision but prior to the conclusion of surgery. If pathologic examination using NLM concludes that there is invasive cancer or ductal carcinoma in situ (DCIS) at or close to the margin of the specimen, the surgeon will be notified and may decide to do additional surgical shavings before the patient leaves the operating room, in order to improve the likelihood of achieving clean margins and reduce the probability that the patient will be advised to have another operation to achieve clean margins. For both patients on the experimental arm (NLM) and the control arm (without NLM), standard pathologic evaluation of the specimen will be done some days after the lumpectomy is completed. That pathologic evaluation will decide whether or not to recommend that the patient has additional surgery in order to achieve clean margins. The primary outcome measure is the percentage of patients in each group who are advised to have additional surgery for this reason.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • nonlinear microscopy imaging of excised surgical marginsDevice

    Following standard lumpectomy excision, excised tissue will be imaged with NLM. If invasive cancer or ductal carcinoma in situ (DCIS) is detected on or close to the margin, additional excision may be performed. Following surgery, final margins will be evaluated using paraffin embedded histopathology as per standard procedure. Paraffin embedded histopathology will be used to make a final margin determination.

  • standard lumpectomy without nonlinear microscopy imagingProcedure or surgery

    Lumpectomy with postoperative paraffin embedded histopathology to make a final margin determination.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Rate of Recommendation for Repeat Surgery on Postoperative Histopathology

    The number of participants in each arm with a recommendation for additional surgery due to positive or close margins on standard postoperative histopathology, as defined by SSO-ASTRO-ASCO guidelines ("no ink on tumor" for invasive cancer with or without DCIS; <2 mm for DCIS).

    Measured: From surgery to postoperative pathology reporting, up to 1 month

Secondary outcomes (1)
  1. Diagnostic Accuracy

    The diagnostic accuracy of intraoperative nonlinear microscopy compared to reference standard postoperative pathology evaluation of the original (pre-shave) lumpectomy margins.

    Measured: From surgery to postoperative pathology reporting, up to 1 month

Questions about this trial

What is this clinical trial studying?

A study testing nonlinear microscopy imaging of excised surgical margins and standard lumpectomy without nonlinear microscopy imaging in people with Breast Cancer, run by Beth Israel Deaconess Medical Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 16 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 16 Sep 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Rate of Recommendation for Repeat Surgery on Postoperative Histopathology (time frame: From surgery to postoperative pathology reporting, up to 1 month). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Sep 2026.
