For patients with breast cancer subject to a mastectomy, preserving the morphology of the breast with immediate reconstruction is a crucial aspect to preserve the quality of life. There are several types of breast reconstruction: prosthetic in one or two stages and autologous reconstruction. Adjuvant radiotherapy has shown an improvement of the overall survival and of the local control for patients with positive lymph nodes. As a consequence, plastic surgeons come into contact with more patients with a history of irradiation of their breasts than ever before. However, there are few studies with a significant number that evaluate the effect of pre-reconstruction radiotherapy on the three types of reconstruction. The aim of this study is to compare retrospectively these three types of reconstruction techniques to evaluate the impact of breast prior irradiation on the outcome of prosthetic reconstruction.
For patients with breast cancer subject to a mastectomy, preserving the morphology of the breast with immediate reconstruction is a crucial aspect to preserve the quality of life. There are several types of breast reconstruction: prosthetic in one or two stages and autologous reconstruction. Adjuvant radiotherapy has shown an improvement of the overall survival and of the local control for patients with positive lymph nodes. Despite the undoubted cancer benefits, several studies have shown the negative impact of radiotherapy on breast reconstruction. However, there are few studies with a significant number that evaluate the effect of radiotherapy on the three types of reconstruction. In particular, given the extreme variability in clinical approaches, there is no certainty about the best reconstructive timing compared to radiotherapy, the iterations with dermic matrices as well as the usefulness of ancillary procedures such as autologous adipose grafting. The aim of this study is to compare retrospectively these three types of reconstruction techniques to evaluate the effect of radiotherapy on different reconstructive modes.
The primary objective of this small feasibility pilot study is to demonstrate that implant-based breast reconstruction (after treatment for cancer) can successfully be performed without prolonged drain placement, using a tissue expander with a reservoir and in-office transcutaneous fluid aspiration. Secondly, the investigators aim to provide enough confidence in this technique that a larger study can be performed to demonstrate fewer complications (infection, drain-related pain and re-operation rates) when compared to the use of conventional tissue expanders and/or implants with prolonged drain placement.
Reconstructive surgery with breast implants after total mastectomy for breast cancer is invariably related to several possible complications, such as atrophy of surrounding tissues, skin thinning, capsular contracture, wound dehiscence and inframammary fold break. Such complications are promoted by elastic properties of tissues and their response to gravity forces exerted on breast implant weight, leading to microischaemic events. A poor cosmetic outcome may result up to breast implant exposure, and its removal may become necessary, thus compromising the quality of breast reconstruction. These complications are further favoured by post-mastectomy radiotherapy (PMRT), since irradiation could enhance microischaemia of peri-prosthetic soft tissues and muscle, with subsequent inadequate healing, fibrosis and thinning. Since PMRT has been associated to improved loco-regional control in node-positive breast cancer patients, its use has increased in recent years. On one hand, PMRT has improved loco-regional control but, on the other hand, it has increased the failure rate of breast reconstruction after total mastectomy. Change of timing in breast reconstruction (immediate vs. two-staged by use of tissue expander) has not decreased the complications rate after PMRT. Currently the failure rate of breast reconstruction after total mastectomy and PMRT ranges from 0% to 40%. The present study will recruit 80 participants affected by breast cancer candidated to total mastectomy with immediate breast reconstruction and subsequent PMRT or total mastectomy with reconstruction by tissue expander, subsequent PMRT and then definitive reconstruction with breast implant. Participants will be randomized in two experimental arms: 40 patients will receive final reconstruction by the use of standard silicone-based breast implant and the other 40 patients will receive B-Lite® light weight breast implant. Participants will be followed up at 1, 6, 12 and 24 months, and all patients will undergo breast MRI at 6 months. The primary goal of the present study is to evaluate the failure rate of breast reconstruction (i.e. the need of re-intervention for breast implant removal). Secondary end-points include the overall complications rate, MRI evaluation of breast implant and surrounding tissues, cosmetic outcomes and quality of life including participants' satisfaction with breast reconstruction.
In breast cancer patients treated by mastectomy and adjuvant post-mastectomy radiation therapy (PMRT) reconstruction is often delayed until 6 - 12 month after completion of chemotherapy and PMRT, due to high risk of complication. In this trial the safety of the delayed-immediate reconstruction method is tested, where a skin sparing mastectomy and reconstruction with silicone implant is performed at primary surgery to save the native skin for the final delayed reconstruction.
The study investigates the safety and performance of Silimed® silicone gel breast implants with a textured surface and Silimed® silicone gel breast implants with polyurethane coated surface. Female patients who underwent primary or secondary breast augmentation using Silimed® breast implants will be followed-up through 10 years. The safety of each type of Silimed® breast implant is going to be assessed by estimating the known and unexpected short- and long-term risk / adverse event rates. The performance of each type of Silimed® breast implant is going to be assesses by estimating the satisfaction and quality of life after implantation.
