Trial summary

Neoadjuvant chemotherapy for advanced breast cancer has led to an increased rate of breast-conserving surgery (BCS) in these patients. As the demand for preoperative localization methods grows among surgeons performing BCS, traditional localization techniques have shown limitations. Read more about this study

About this study

Official title: Surgical Outcome of Breast Conserving Surgery Using Indocyanine Green Fluorescence in Breast Cancer Patients After Preoperative Chemotherapy: a Prospective Study

Neoadjuvant chemotherapy for advanced breast cancer has led to an increased rate of breast-conserving surgery (BCS) in these patients. As the demand for preoperative localization methods grows among surgeons performing BCS, traditional localization techniques have shown limitations. For non-palpable breast lesions, preoperative localization has commonly been achieved using ultrasound-guided skin markings or needle localization. However, these methods present challenges, including difficulty in depth localization for patients with large breasts and limitations in real-time re-verification during surgery due to air artifacts after incision. Needle localization, although commonly used, is invasive and poses risks such as displacement or detachment of the needle.

Indocyanine green (ICG), a fluorescent dye that appears green to the naked eye and is detectable by near-infrared (NIR) cameras, has been widely and safely used in clinical practice via intravenous or subcutaneous administration. Recently, ICG combined with NIR imaging has been adopted for sentinel lymph node biopsy in breast cancer and melanoma surgeries and is increasingly used as a localization method for various tumors, replacing conventional techniques.

A preliminary study (IRB No. NCC2016-0071) conducted at the institution evaluated ICG injection and NIR fluorescence imaging for tumor localization in early breast cancer patients undergoing BCS. The study demonstrated the efficacy of ICG-based localization in reducing the rate of positive surgical margins.

The objective of this study is to evaluate the effectiveness of ICG-guided tumor localization with NIR fluorescence imaging in patients with advanced breast cancer treated with neoadjuvant chemotherapy. It is hypothesized that this technique will allow for more accurate tumor excision compared to conventional methods, ultimately improving surgical outcomes.

What is being measured

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

  1. Margin-positive rate in final pathological report

    Collection of data for margin-positive rate from final pathological report after surgery

    Measured: 10~35 days after surgery (the date when the pathological reports are available)

Secondary outcomes (6)
  1. Localization rate

    Collection of data for tumor detection rate using ICG-F

    Measured: The day of surgery

  2. Centralization

    Collection of data for the lengths from tumor to each resection margins

    Measured: 10~35 days after surgery (the date when the pathological reports are available)

  3. Margin-positive rate in frozen section

    Collection of data for margin-positive rate in frozen section during surgery

    Measured: The day of surgery

  4. Additional resection rate

    Collection of data for additional resection rate according to results of frozen section during surgery

    Measured: The day of surgery

  5. Re-excision rate

    Collection of data for re-excision rate (2nd operation) according to final pathological results

    Measured: 10~35 days after surgery (the date when the pathological reports are available)

  6. Adverse event rate

    Collection of data for pigmentation rate of the injection site

    Measured: 10~35 days after surgery (the date of follow-up after surgery)

Questions about this trial

What is this clinical trial studying?

A study testing The margin-positive rate using the localization technique in people with Breast Neoplasms and Breast Cancer, run by National Cancer Center, Korea at 1 site in South Korea.

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 4 inclusion and 6 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: looking for participants now, as of the sponsor's last update on 13 Mar 2025. 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 South Korea. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Seeyoun Lee, MD (+82-31-920-1736 ext. 1736, seeyoun@ncc.re.kr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Margin-positive rate in final pathological report (time frame: 10~35 days after surgery (the date when the pathological reports are available)). 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 13 Mar 2025.
