简介：
Overview
This protocol outlines a technique for image-guided infusion into the ductal tree of the rabbit mammary gland. The method allows for controlled infusion of an ablative solution using fluoroscopy for real-time imaging.
Key Study Components
Area of Science
Background
- Breast cancer is a leading cause of cancer-related deaths.
- Current preventive measures for high-risk women have significant side effects.
- A less invasive alternative to mastectomy is needed.
- Previous studies showed the effectiveness of intraductal infusion of ethanol in mouse models.
Purpose of Study
- To develop an intraductal delivery technique for ablating mammary epithelial cells.
- To scale the procedure to a rabbit model with a multi-duct tree system.
- To confirm the technique's effectiveness for potential human application.
Methods Used
- Preparation of the rabbit by removing fur and administering anesthesia.
- Intravenous catheterization for emergency drug administration.
- Cannulation of the ductal openings for infusion of the ablative solution.
- Real-time fluoroscopy imaging to confirm successful infusion.
Main Results
- The technique successfully filled the ductal tree with the ablative solution.
- Fluoroscopy provided immediate confirmation of infusion success.
- Tissue analysis post-procedure assessed the effectiveness of the treatment.
- Various ethanol concentrations were tested for optimal ablation.
Conclusions
- The intraductal infusion technique is a promising alternative to mastectomy.
- Rabbits serve as a suitable model for further translational research.
- This method may reduce the incidence of breast cancer in high-risk individuals.
What is the main goal of this study?
To develop a less invasive technique for ablating mammary epithelial cells to prevent breast cancer.
Why use rabbits for this procedure?
Rabbits have a multi-duct tree system, making them a relevant model for translational applications.
What imaging technique is used during the procedure?
Fluoroscopy is used for real-time imaging to guide the infusion process.
What type of solution is infused into the ductal tree?
An ethanol-based ablative solution is infused to target mammary epithelial cells.
How is the success of the infusion confirmed?
Success is confirmed through fluoroscopy imaging immediately after infusion.
What are the potential benefits of this technique?
It offers a less invasive alternative to mastectomy with fewer side effects for high-risk women.
