About this study
Official title: Comparison of Ultrasound Guided Percutaneous Microwave Ablation With Cryoablation for Breast Tumor
The investigators will perform this study to prospectively compare the clinical outcome after percutaneous microwave ablation(MWA) and cryoablation of benign and malignant breast lesion under ultrasound (US) guidance.
Read the detailed description
A total of more than 200 patients diagnosed with benign breast lesions and 50 patients with malignant breast lesions in two centers of China will be recruited in this study and underwent US-guided percutaneous MWA and cryoablation treatment. Information for each patient includes demographics; longest diameters of tumors; tumor numbers; tumor pathological type; location of tumor according to whether adjacent to skin, pectoralis, areola and papilla. Ablation variables including session, puncture, time, and power; complete ablation, complications; reduction in volume, palpability, pain and cosmetic satisfying outcomes,recurrence,survival will be compared and analyzed.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
microwave ablationProcedure or surgery
Also called cryoablation
Microwave ablation and cryoablation are both thermal ablation techniques for minimally invasive treatment of breast tumor. They are performed percutaneously by ultrasound guidance.The tumor can be completely killed without injurying adjacent tissue.
| Study group | Role | What they receive |
|---|---|---|
| microwave ablation | Experimental | Microwave ablation（MWA）refers to all electromagnetic methods of inducing tumor destruction by using devices with frequencies greater than or equal to 900MHz. The rotation of dipole molecules accounts for most of the heat generated during MWA. Water molecules as dipoles attempt to continuously reorient at the same rate in microwave's oscillating electric field. As a result of microwave transmission, the water molecules flip back and forth billions of times a second. The vigorous movement of water molecules produce friction and heat, thus inducing cellular death via coagulation necrosis. The microwave unit (KY-2000, Kangyou Medical, Nanjing, China) is capable of producing 100 Watts of power at 2450 MHz.The needle antenna has a diameter of 1.6 mm (16G) and a length of 10 cm. The active tip length is 3mm and 5mm. Receives: Procedure: microwave ablation |
| cryoablation | Active comparator | Clinically, cryosurgery is accomplished by placing a cryoprobe(up to 3.5 mm) through a stab incision into the tumor under ultrasound guidance.Liquid nitrogen is utilized under low operating pressure as cryogen which is controlled by the computer modulated cryogen regulator. The cryoprobe achieves rapid freezing by means of an active freeze zone at its distal tip. Receives: Procedure: microwave ablation |
What is being measured
The primary outcome is the main question the study is designed to answer.
volume reduce rate

complication
numbers of participants with side effect and major complications
Measured: 5 year
