Using LUminoMark vs Coventional Practice for Targeted Axillary Surgery (LUCAS)

March 24, 2025 updated by: JeeYeon Lee, Kyungpook National University Chilgok Hospital

A Comparative Study to Evaluate Targeting Methods for Axillary Surgery in Patients With Clinically Node-positive Breast Cancer: A Prospective Multicenter Pilot Study

The purpose of this study was to compare the use of LuminoMarkTM as a method of targeting axillary lymph nodes with other existing methods used in each institution, such as charcoal staining, needle targeting, and ultrasound-guided skin marking, in patients with breast cancer clinically suspected of metastasis, with or without clipping at the time of diagnosis, regardless of the presence or absence of neoadjuvant chemotherapy. By doing so, the investigators aimed to confirm the safety and usefulness of LuminoMarkTM as a targeting method.

Detailed Description

In breast cancer patients, lymph node targeting plays an important role in determining the stage and setting the treatment policy, and the existing methods for this purpose include charcoal staining, needle targeting, and ultrasound-guided skin marking. However, these methods have limitations in terms of detection rate and accuracy, and a new targeting method, LuminoMarkTM, shows the potential to replace them. The purpose of this study is to evaluate the detection rate and safety of lymph node targeting using LuminoMarkTM in breast cancer patients and to verify its effectiveness by comparing it with existing targeting methods. The study was designed as a prospective comparative study, and patients diagnosed with breast cancer and requiring lymph node targeting were divided into the LuminoMarkTM group and the existing method group. The existing method group selects a standard method among charcoal staining, needle targeting, and ultrasound-guided skin marking to perform targeting, and the lymph node detection rate, procedure time, complication rate, and patient satisfaction are the main evaluation indicators in both groups. After targeting, the suitability of the detected lymph nodes is confirmed through pathological analysis, and appropriate statistical analysis is performed to compare the difference in detection rates of each method. Through this study, the investigators evaluate whether LuminoMarkTM provides superior detection rates and safety compared to existing lymph node targeting methods, and based on this, the investigators aim to suggest a more effective and reliable targeting method for breast cancer patients.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Accuracy of the axillary lymph node targeting method
Time Frame: From enrollment to the end of observation at 3 weeks

The outcome will be assessed by determining whether the preoperatively marked (targeted) lymph node is successfully identified and retrieved during surgery, and confirmed by postoperative pathological examination.

Success (match): The retrieved lymph node is matched with targeted lymph node.

Failure (not match): The retrieved lymph node is not matched with targeted lymph node.
From enrollment to the end of observation at 3 weeks
Comparison the accuracy rate between LuminoMark group and conventional group
Time Frame: At the end of the trial (up to 1 year)
Compare the rate at which the lymph nodes are accurately detected using charcoal staining, needle targeting, ultrasound-guided marking, etc., with the rate at which they are detected using LuminoMark.
At the end of the trial (up to 1 year)

Secondary Outcome Measures
