Mammary ductoscopy (MD) is a feasible endoscopic technique for early breast cancer detection and guiding surgery. While safe in office settings for pathological nipple discharge, its cytology lacks sensitivity for malignancy diagnosis.
Area of Science:
- Oncology
- Surgical Endoscopy
- Diagnostic Imaging
Background:
- Mammary ductoscopy (MD) utilizes microendoscopes for direct visualization of the mammary ductal epithelium.
- The technique allows for insufflation, irrigation, lavage, and potential therapeutic interventions within the ducts.
- MD can be performed in an office setting under local anesthesia.
Purpose of the Study:
- To assess the technical feasibility of mammary ductoscopy.
- To evaluate its role in guiding ductal excision surgery.
- To examine its utility in the early diagnosis of breast malignancy.
Main Methods:
- Mammary ductoscopy performed on 26 patients using a 1 mm fiberoptic microendoscope.
- 13 patients undergoing surgery for ductal carcinoma (DCIS, infiltrating ductal carcinoma).
- 13 patients with pathological nipple discharge (PND) and benign findings, with procedures under local or general anesthesia.
Main Results:
- Intraoperative MD successful in 84.6% of patients undergoing surgery for DCIS.
- Intraductal pathology visualized in 80% of mastectomy cases; cytology sensitivity for malignancy was 16%.
- In PND cases, MD was successful in 90% and well-tolerated; findings included papilloma, duct ectasia, and suspicious lesions.
Conclusions:
- Mammary ductoscopy is technically feasible and shows potential for early breast cancer detection.
- The procedure is safe for office settings and recommended for single-duct PND.
- MD may reduce the need for extensive surgical resection, but improved biopsy tools are needed for malignancy diagnosis.
