简要总结
Image-guided tumor ablation is a non-surgical, minimally invasive therapy available for local therapy of some carcinomas as an alternative to surgical treatment. This study assesses whether cryoablation can be used as an alternative to surgery in cases of early invasive breast carcinoma.
详细描述
Purpose: To evaluate the effectiveness of cryoablation in the local treatment of breast cancer, through the absence of neoplastic cells (invasive or in situ).

结局指标
主要结局
Tumor ablation
时间窗: 1 month
Successful tumor ablation will be defined as absence of residual viable invasive or in situ carcinoma in the surgical specimen.
次要结局
- Negative predictive value of magnetic resonance imaging (MRI)(14 days and 28 days)
- Accuracy of conventional imaging methods (mammography and ultrasound)(14 days and 28 days)
- Measurement of the ice ball by ultrasound(14 days and 28 days)
