What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests a new minimally invasive treatment that freezes and then heats breast tumors, comparing it to standard breast-conserving surgery in 264 women with early-stage, hormone-positive breast cancer. The goal is to see if the ablation method can control the cancer just as well while improving breast appearance and reducing recovery time. Participants must be 50 or older with a single small tumor and no lymph node involvement.

Participants

About 264 people

The number the study aims to enrol. It can still change while the study runs.

Started

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Inclusion Criteria: * 1.Age ≥50 Years 2.Unifocal disease (single tumor) confirmed by ultrasound, MRI, or mammography. Ultrasound visibility: Essential for precise intraoperative ablation targeting. 3.Pathologically Confirmed Invasive Ductal Carcinoma (IDC)。Diagnostic Method: Core needle biopsy (CNB) confirming IDC. 4.Histologic Grade: G1 or G2; ER/PR-positive and HER2-negative. 5.TNM stage: IA. Tumor Size: ≤2 cm; Lymph Node Status: Clinically \& radiologically negative (no palpable/imaging-detected axillary involvement). 6.Written consent for clinical trial participation and acceptance of random assignment Exclusion Criteria: * 1.Extensive intraductal component (EIC) suggested by imaging or pathology. 2.Invasion of adjacent skin or muscle. 3.Prior anticancer treatment for the current disease, including but not limited to chemotherapy, endocrine therapy, targeted therapy, or immunotherapy. 5.Refusal to undergo breast-conserving surgery. 6.Pregnancy or lactation. 7.Previous radiotherapy to the affected breast or other contraindications to radiotherapy. 8.Concurrent untreated malignancies or severe systemic diseases， 9.Known allergy, intolerance, or contraindications to cryotherapy (e.g., cryoglobulinemia, implanted electronic devices). 10.Inability to comply with follow-up or refusal of adjuvant therapy. 11.Vulnerable populations, including individuals with neurological disorders, cognitive impairment, or critical illness.
