Polyurethane-Coated Implants Reduce Complications in Post-Mastectomy Breast Reconstruction
Women undergoing breast reconstruction after mastectomy may experience fewer complications with polyurethane-coated implants, according to recent research presented at the European Breast Cancer Conference in Barcelona. The study suggests these implants reduce the risk of capsular contracture – a hardening of the scar tissue around the implant – and the require for additional surgeries.
Understanding Breast Reconstruction and Complications
Approximately 30% of the 55,000 women diagnosed with breast cancer annually in the UK undergo mastectomy. Many women choose reconstructive surgery following a mastectomy, and often require subsequent radiotherapy. However, radiotherapy can increase the risk of complications, including capsular contracture, rupture, migration, rotation, rippling, and asymmetry, potentially leading to further corrective surgery in up to 30% of cases.
How Polyurethane-Coated Implants Differ
Traditional breast implants utilize silicone as the filler material, with variations in the outer shell’s appearance and texture between manufacturers. Polyurethane-coated implants, however, feature a silicone base encased in a spongy outer layer of polyurethane. This coating appears to mitigate some of the risks associated with traditional implants.
Study Findings: Reduced Scar Tissue and Re-operations
The European study, involving approximately 1,500 women across 15 countries treated between 2016 and 2024, compared outcomes for those receiving polyurethane-coated implants versus standard implants after mastectomy and radiotherapy.
Preliminary results indicate that 32.8% of women with polyurethane-coated implants developed capsular contracture, significantly lower than the 47.5% observed in those with standard implants. Patients with the coated implants were less likely to require secondary surgery to remove scar tissue or experience major breast infections.
Expert Perspectives
Dr. Kerstin Wimmer, a surgeon at the Medical University of Vienna, stated that the study “suggests that women who received polyurethane-coated implants had far fewer problems after radiotherapy than those who received standard implants.”
Prof. Isabel Rubio, Head of Breast Surgical Oncology at the Clínica Universidad de Navarra in Madrid, emphasized the potential for improved patient comfort, aesthetic outcomes, and overall quality of life.
Catherine Priestley, senior clinical nurse specialist at Breast Cancer Now, highlighted the importance of comparing implant compatibility with radiotherapy to enable more informed patient choices.
Looking Ahead
Sarah Downey, president of the Association of Breast Surgery, acknowledged the value of breast implants in restoring confidence and improving quality of life for patients undergoing reconstruction. Further research is anticipated to refine implant selection and treatment planning for women requiring post-mastectomy reconstruction and radiotherapy.
