About this trial

This retrospective cohort study investigates the differences in the reliability of rapid pathology compared to postoperative pathology when utilizing a novel fluorescent localization needle equipped with a controllable shedding quantum dot chiral nanofluorescent coating, in contrast to traditional localization techniques for breast duct lesions. The primary goal is to evaluate the clinical effectiveness of this innovative fluorescent localization needle in facilitating accurate pathological diagnoses of micro lesions situated within breast ducts.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Female patients aged 18-75 years.

Patients who have been diagnosed intraductal breast lesion by ductoscopy.

Patients who have undergone ductal excision.

Disqualifiers

Pregnant or breastfeeding.

Patients who have known allergy to quantum-dot materials or localization needle components.

Patients with active hepatitis B or C infection with detectable viral load.

Patients with unstable cardiovascular disease (e.g., recent myocardial infarction, uncontrolled arrhythmia, NYHA class III-IV heart failure).

Trial population

This retrospective study estimated enroll 300 patients diagnosed with intraductal breast lesion by ductoscopy at the Fourth Affiliated Hospital of China Medical University between January 2023 and December 2024. All participants met inclusion criteria, and underwent ductal excision utilizing a novel fluorescent localization marker needle or conventional localization methods.
