Brief summary
This study aims to evaluate the efficacy of using a polyester mesh endoprosthesis with a fluoropolymer coating in reducing postoperative complications, particularly protrusions, following subcutaneous mastectomy with simultaneous prepectoral placement of textured breast implants in women with breast cancer
Detailed description
The study includes female patients aged 18 and above with a verified breast cancer diagnosis, ECOG performance status 0-1, and clinical stage T1-T3, N0-3, M0, who provide informed consent. Exclusion criteria involve intolerance or allergic reactions to mesh endoprostheses or implants and a subcutaneous adipose tissue thickness of less than 5 mm (measured via Pinch Test). Participants will be non-randomly allocated into two groups: the main group, receiving a polyester mesh endoprosthesis with fluoropolymer coating alongside textured implants, and the control group, receiving textured implants alone. Surgical procedures will involve subcutaneous mastectomy with implant placement based on preoperative measurements of breast dimensions, with or without nipple-areolar complex preservation. Postoperative follow-ups at 1, 3-6, and 9-12 months will assess complications such as protrusions, seromas, implant contouring (rippling), capsular contracture, and dystopia via physical examination and ultrasound. The hypothesis posits that the use of mesh endoprostheses will lower protrusion rates compared to standard implant placement, offering a potential advancement in reducing postoperative risks in breast reconstruction for breast cancer patients.
Interventions
PROCEDURESubcutaneous mastectomy using a fluoropolymer-coated polyester mesh endoprosthesis with simultaneous prepectoral placement of textured implants.
For this group of patients, the planned volume of surgical intervention is: subcutaneous mastectomy using a polyester mesh endoprosthesis with a fluoropolymer coating and one-stage prepectoral installation of textured implants.
PROCEDURESubcutaneous mastectomy with simultaneous prepectoral placement of textured implants.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Frequency of protrusions throughout the year | 1 year | Implant protrusion is a complication that occurs after reconstructive plastic surgery. In this type of surgery, the implant is displaced from its anatomically correct position leading to its protrusion through the skin. This happens when the integrity or strength of the tissues that hold the implant (such as capsules, muscles, and fascia) is compromised. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| 1. Frequency of seroma 2. Frequency of Rippling 3. Frequency of Capsular contracture 4. Frequency of Dystopia | 1 year | 1. Seroma is a pathological accumulation of serous fluid in the tissues after surgery or trauma. Most often, this condition develops after operations that affect large areas of the skin and subcutaneous fat. 2. Rippling - represents contouring of the implant through the surface of the mammary glands, expressed by folds in the area of implantplacement.Sometimes it is called skin ripples orwashboard effect. 3. Capsular contracture is the formation of connective tissue around the implant, resulting in compression and deformation of the prosthesis. 4. Dystopia is a displacement of the implant relative to its original correct anatomical position, which leads to breast deformity, asymmetry, or functional discomfort |
