About this trial
LUBRECA will evaluate the safety and efficacy of cryoablation with liquid nitrogen to treat cT1cN0 luminal breast cancer diagnosed in postmenopausal women
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Postmenopausal women diagnosed with invasive breast cancer by core needle biopsy or vacuum-assisted biopsy
Unifocal
Lesion ≤ 2 cm (on ultrasound and contrast enhanced mammography)
No axillary lymphadenopathy on ultrasound
Disqualifiers
Infiltrating lobular carcinoma
Extensive in situ component
Multifocality or multicentricity
Contraindication for contrast mammography
Trial design
Single group
Treatments tested in this trial
Cryoablation with liquid nitrogen (Prosense® system)
DeviceThe appropriate cryoprobe (10G or 13G) will be selected depending on the size of the tumor. After injecting local anesthesia, the cryoprobe will be inserted along the longest diameter of the lesion. The tip of the needle will be advanced so that the freezing center is located in the middle of the tumor. Two freezing cycles will be performed, separated by a thawing cycle, all three of the same duration, which depends on the size of the tumor. The goal is a freezing volume with a lethal zone covering the lesion and a safety margin of at least 1 cm. Ultrasound allows real-time monitoring of the expansion of the ice ball during cryoablation. To avoid burning the skin, we will inject warm sterile saline solution when the distance between the ice and the skin surface is less than 0.5 cm
