Clinical Trial Summary

The goal of this observational study is to learn about correct surgical indications and long-term complications in patient with immediate prepectoral breast reconstruction with polyurethane implants. The main question it aims to answer are: what are the correct indications for this type of reconstruction? what is the complications rates? are the complications affected by pre and post operative radiotherapy? It's a retrospective study of all the patients that received prepectoral breast reconstruction with polyurethane implants without any exclusion factors. Researchers will compare the non-irradiated group with the patients with pre and post radiation therapy.


Description:

The study is a data collection of 250 patients for a total of 317 breasts underwent prepectoral breast recosntruction with polyurethane implantes. It is a retrospective study of a single center. The investigators gave indication to that type of reconstruction only to patients with good thickness (> 0.5 cm) and vascularity of skin flap after mastectomy. The investigators used not selective criteria regarding risk factors so to better evaluate wich of them has a negative trend on the success of the reconstruction and on the major and minor complications. In that way the investigators tried to definde clarly the correct indications for this type of reconstruction. In addition, the investigators would like to define if the postoperative radiation therapy agument the complications rate and the capsular contracture incidence. The investigators decide to perform prepectoral breast reconstruction also in 20 patientes underwent previous radiotherapy dependig on the grade of cutaneus radiodistrophy, so to propose our less invasive approach to these patients normally candidates to autologus breast reconstruction

Intervention

Procedure:
Prepectoral breast reconstruction with polyurethane implants
Breast reconstruction in the prepectoral plane without elevate the pectoralis major muscle. We choose this type of reconstruction only in patients with mastectomy flap thickness of plus then 0.5 cm. We usally use silicone implants covered by an external layer of polyurethane so not to put directly in contact the silicone with the subcutaneus tissue.

Outcome

Type Measure Description Time frame Safety issue
Primary reconstruction failure loss of implant or switch to autologus recosntruction 12 months
Primary major complications evaluation of hematoma, infection, flap necrosis, wound dehiscence rate 12months
Primary minor complications evaluation of seroma, rippling, casular contracture, asymmetry rate 12 months
Primary risk factor evaluation of the risk factors correlated to recostruction failure 12 months
Secondary postoperative radiation therapy on patients underwent prepectoral breast reconstruction with polyurethane implantes evaluation if the post operative radiation therapy is correlated with an increase of reconstruction failure and capsular contracture 12 months
Secondary patients previously irradiated (QUART) and underwent prepectoral breast reconstruction with polyurethane implantes analysis of clinical characteristics of pre irradiatred patients submitted to prepectoral breast recosntruction with polyurethane implantes 12 months
