No results posted yet for this study

Summary

Expanders are used outside their intended use, due to two following facts: It is possible that expander implantation exceed the "approved" duration of 6 months (maximal 10 months). Additionally, some participants will receive after mastectomy/expander implantation an adjuvant radiotherapy according to standard of care, which is either a contraindication of the medical device or not yet tested in-vivo by the manufacturer.

Requested answers:

* how good is the aesthetic outcome of the breast with the expanders and the final implants, and whether any complications occurred during treatment,
* how satisfied are subjects and doctors with the outcome of the breast reconstruction, and how the reconstruction affects health-related quality of life from participants,
* how does the structural composition of the removed expanders looks like, in order to understand whether radiation therapy has caused changes in the material,
* which key immunological factors lead to increased hardening of the tissue around the expander, especially during radiation therapy (capsule formation).

Conditions

  • Mastectomy and Breast Reconstruction
  • Tissue Expander Based Breast Reconstruction
  • Adjuvant Radiotherapy
  • Long Term Outcome

Interventions

RADIATION

intervention (unilateral/bilateral), scheduled for (NSME/SSME), indication (breast cancer diagnosis (malignancy) with neoadjuvant chemotherapy or DCIS diagnosis without neoadjuvant chemotherapy

Patients who are scheduled for tissue expander-based breast reconstruction will be randomized in one of two expander groups (Arm 1= Motiva Flora® Tissue Expander \& Arm 2 = SILTEX™ BECKER™ expander). Subjects, who are routinely scheduled for radiotherapy (collective I) will subsequently undergo two additional visits. Subjects without scheduled radiotherapy (collective II), will continue without additional visits - unless they need to change their collective for therapeutic reasons. Assesments: 1. efficacy and safety of therapeutic and prophylactic comparative tissue expander-based breast reconstruction 2. structural and functional changes in comparative tissue expanders following exposure to radiotherapy vs. non-radiotherapy
