Outcome Measures

Primary Outcomes (1)

  • Incidence of serious complications after breast reconstruction surgery

    All surgical related complications (including hematoma, poor wound healing, skin flap necrosis, infection, incision dehiscence, fat injection related complications, etc.) are classified according to the Clavien Dindo scoring system. The Clavien Dindo grading system is based on the severity of postoperative complications and whether corresponding treatment is needed for the complications. Postoperative complications are classified into grades I-V, and those classified as grade III or above by Clavien Dindo are considered serious complications.

    One week after surgery, one month after surgery, three months after surgery, six months after surgery, and one year after surgery

Secondary Outcomes (7)

  • BREAST-Q (Breast Reconstruction Module) score

    BREAST-Q scoring was performed at preoperative, postoperative 1-month, 3-month, 6-month, and 12-month follow-up

  • Success rate of breast reconstruction

    One year after surgery

  • All incidence of complications

    On the day of surgery, one week after surgery, one month after surgery, three months after surgery, six months after surgery, and one year after surgery

  • Breast cosmetic effects evaluated by doctors

    Before surgery,on the day of surgery, one months after surgery,three months after surgery, six months after surgery, and one year after surgery

  • Occurrence of capsule contraction

    one months after surgery,three months after surgery, six months after surgery, and one year after surgery

  • +2 more secondary outcomes

Eligibility Criteria

Age18 Years - 70 Years
Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Women aged 18 to 70 years old;
  • In the first diagnosis of unilateral breast cancer patients, the maximum diameter of invasive tumor is ≤ 5cm, and there is no requirement for tumor size of carcinoma in situ in principle;
  • Patients undergoing preventive mastectomy are not allowed to be included in the study;
  • Clinical examination and auxiliary examinations suggest that the tumor is confined to the mammary gland and has not invaded the nipple areola complex, skin, or chest wall;
  • Clinical axillary lymph node negative (clinical physical examination and imaging suggest negative axillary lymph nodes; for suspected positive axillary lymph nodes, fine needle aspiration or hollow needle biopsy is required to confirm negative);
  • Sentinel lymph node biopsy negative;
  • Patients with low load positive axillary lymph nodes (isolated tumor cells, micro or macro metastases), but exempted from adjuvant radiotherapy after surgery;
  • Patients who are not suitable for breast conserving surgery or who are unwilling to undergo breast conserving surgery and plan to undergo laparoscopic assisted mastectomy with preservation of the nipple and areola, as well as immediate one-step breast reconstruction with a breast prosthesis combined with a chest muscle prosthesis and simultaneous fat transplantation; If frozen pathology or routine pathology indicates a positive posterior margin of the nipple, it is allowed to remove the nipple, but the areola must be preserved;
  • The volume of the prosthesis is less than 500cc;
  • During the observation period of the study, the affected side may consider re fat injection, but symmetrical surgery is not allowed on the healthy side;
  • ECOG score 0-1 points;
  • New adjuvant chemotherapy patients are allowed to be enrolled;
  • No smoking history or quitting smoking for at least 4 weeks;
  • The researcher determines that they are able to comply with the research protocol;
  • Those who participate in other clinical trials (including intervention or non intervention studies) at the same time and are judged by the researchers to not affect the study protocol can be enrolled normally;
  • +1 more criteria

You may not qualify if:

  • Specialized physical examination and/or auxiliary examination suggest that the tumor involves the nipple areola complex (including Paget's disease) or the skin;
  • Double breast cancer;
  • Bilateral breast reconstruction patients;
  • Patients who have undergone fat injection, breast augmentation with implants, and breast reduction surgery in the past;
  • Patients with incomplete immune function, poor control of diabetes and active smoking;
  • Patients with severe breast sagging;
  • Breast cup size ≥ E;
  • Accept two-step breast reconstruction using dilators/prostheses, autologous breast reconstruction, and breast reconstruction performed through open surgery;
  • Patients who have previously received and/or received postoperative radiotherapy for the reconstruction site or chest wall;
  • Patients who plan to undergo symmetrical surgery on the healthy breast during the visit period;
  • Patients with mental illnesses or abnormalities who are expected to be unable to independently complete the BREAST-Q scale;
  • Pregnant and lactating patients;
  • Poor compliance, unable to conduct relevant examinations and follow ups according to the trial requirements;
  • Suffering from serious accompanying diseases or other comorbidities that may interfere with planned treatment, or any other circumstances that the researcher deems unsuitable for the patient to participate in this study.
