入选标准
- •Competent to sign informed consent
- •Diagnosis of invasive ductal breast carcinoma by core needle biopsy, meeting the following criteria:
- •Unifocal primary disease NOTE: Patients with multifocal and/or multicentric in breast cancer, or evidence of EIC are NOT eligible. Patients with contralateral disease will remain eligible.
- •Tumor size ≤1.5 cm in greatest diameter in the axis parallel to the treatment probe AND ≤1.5 cm in the axis anti-parallel to the treatment probe AND ≤1.5 cm in Anterior/ Posterior dimension. Tumor size ≤1.5 cm in greatest diameter as measured by breast ultrasound, mammogram and/or MRI. The largest dimension measured will be used to determine eligibility.
- •Nottingham grade 1-
- •Specifically, nuclear and mitotic scores must be less than or equal to
- •Estrogen receptor-positive, progesterone receptor-positive, HER2 negative
- •Breast size adequate for safe cryoablation
- •Lesion must be sonographically visible at the time of treatment.
- •History of previously treated ipsilateral or contralateral breast carcinoma is not an
排除标准
- •if the investigator is certain newly diagnosed carcinoma is new unifocal primary tumor.
- •Exclusion Criteria:
- •Presence of lobular carcinoma
- •Presence of luminal B pathology
- •Nottingham score of 3 (specially nuclear and mitotic score>2)
- •Presence of microinvasion, or invasive breast carcinoma with extensive intraductal component (EIC)
- •Presence of multifocal and/or multicentric in breast cancer
- •Presence of multifocal calcifications
- •Presence of prior or concurrent neoadjuvant chemotherapy for breast cancer
- •Presence of prior en bloc open surgical biopsy and/or lumpectomy for diagnosis/treatment of the index breast cancer
- •Patient that is not suitable to cryoablation procedure according to the physician opinion
- •ER AND PR negative, or Her2 positive noted on pre-cryo biopsy
