Single-Stage Prepectoral Placement of Textured Implants Using a Polyester Mesh Endoprostheses With Fluoropolymer Coating in Patients With Breast Cancer

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.
