application of single-port robot-assisted breast-conserving surgery via axillary approach for breast cancer.

Conditions: Invasive Breast Carcinoma

Summary: evaluate the safety and feasibility of single-port robotic surgery in breast-conserving surgery, compare and analyze the advantages and disadvantages of single-port robotic surgery and open surgery in terms of complications, postoperative complications, perioperative recovery effects, and safety in breast cancer breast-conserving surgery, in order to select a more effective and safe surgical method. subjects who meet the inclusion criteria will enter the research process, with surgery including spr-breast-conserving surgery or open-breast-conserving surgery, and the choice of the two surgical methods is based on the patient's financial situation and the availability of equipment;

evaluate the safety and feasibility of single-port robotic surgery in breast-conserving surgery, compare and analyze the advantages and disadvantages of single-port robotic surgery and open surgery in terms of complications, postoperative complications, perioperative recovery effects, and safety in breast cancer breast-conserving surgery, in order to select a more effective and safe surgical method. subjects who meet the inclusion criteria will enter the research process, with surgery including spr-breast-conserving surgery or open-breast-conserving surgery, and the choice of the two surgical methods is based on the patient's financial situation and the availability of equipment; - preoperative hospitalization period: collect patient disease information (including mammography, breast ultrasound, breast enhanced mri, etc.) - on the day of surgery: record operating time, intraoperative blood loss, intraoperative complications, intraoperative adverse events, etc.; - postoperative hospitalization period: record postoperative complications (postoperative bleeding, necrosis of the flap or nipple-areola complex, subcutaneous emphysema, infection, capsule spasm, postoperative shoulder pain and discomfort, etc.), postoperative pain scores, postoperative pathological biopsy; - postoperative hospital stay: calculated from the day of surgery to the day of discharge; - 28 days postoperatively: understand the complication rate and mortality rate within 28 days postoperatively; - 90 days postoperatively: understand the complication rate and mortality rate within 90 days postoperatively; - 3-year disease-free survival period (calculated from the time of surgery to the last follow-up or recurrence and metastasis date, recurrence is defined as recurrence in the surgical area and distant metastasis); - 3-year overall survival rate (calculated from the time of surgery to the last follow-up or death).

Eligibility criteria:
inclusion criteria: 1. the patient himself has very high requirements for beauty, and requires no scar on the chest; 2. no chest surgery and radiotherapy. 3. no contraindications to surgery and anesthesia. 4. clinical i, stage of early breast cancer and the breast has an appropriate volume, can maintain a good breast shape after surgery. 5. patients in the clinical period who meet the standard of breast conservation surgery after preoperative treatment. 6. age: 18 and 65 years old. exclusion criteria: 1. inflammatory breast cancer. 2. the tumor is extensive and it's difficult to achieve negative margins or an ideal breast - conserving appearance. 3. diffusely distributed malignant - characteristic calcifications. 4. the margin is positive after local extensive tumor resection, and a negative margin in pathological examination still can't be ensured after re - resection. 5. the patient refuses.
