Ablation Compare With Surgery for Early Breast Cancer

Recruiting now · Not applicable

Conditions studied: Breast Cancer, Early Stage, Hormone Receptor Positive, Ablation

In brief

Breast-conserving surgery has been widely used in clinical practice, but surgical incisions still impact postoperative patient satisfaction with breast appearance. The development of tumor ablation technologies has introduced new possibilities for breast cancer surgical treatment. The hybrid cryo-thermal ablation system, an advanced minimally invasive tumor treatment device independently developed in China, employs a combined approach of deep cryoablation and high-intensity heating for therapy and has been approved for treating solid tumors, including breast cancer. This study is a prospective, single-center, randomized controlled trial. Eligible patients with newly diagnosed early-stage breast cancer treated at the Breast Center of Peking University People's Hospital will be enrolled and randomized in a 1:1 ratio to receive either hybrid cryo-thermal ablation (experimental group) or breast-conserving surgery (control group). Data collected will include: Baseline clinicopathological characteristics， Surgical details (operation time, intraoperative/postoperative complications, etc.)， Peripheral blood lymphocyte distribution， Treatment efficacy (ipsilateral breast tumor recurrence rate, disease-free survival, overall survival)， Aesthetic outcomes (BREAST-Q score). Primary endpoint: Ipsilateral breast local recurrence rate， Secondary endpoints: Safety (incidence of adverse events assessed by CTCAE criteria)， Disease-free survival and overall survival， Quality of life assessment (breast satisfaction)， Exploratory endpoints: Pathological response of ablated tumor tissue， Correlation analysis between postoperative imaging (MRI/ultrasound) features and recurrence risk.
