Breast reconstruction following mastectomy

Breast reconstruction after mastectomy can avoid a permanent deformity. As a member of the breast management team, the reconstructive surgeon can give advice on timing and techniques. Breast reconstruction can either be started at the time of the mastectomy or delayed for months or years. Newer techniques of tissue expansion permit breast reconstruction without additional scars or significant hospitalization. Autogenous tissue breast reconstruction techniques are available that provide natural, long-lasting breast reconstruction without the need for a silicone breast implant.     

Direct to Implant Breast Reconstruction With Prepectoral Micropolyurethane Foam-Coated Implant: Analysis of Patient Satisfaction

BackgroundImmediate implant reconstruction after mastectomy with submuscular implant placement is widely used in order to avoid implant exposure, capsular contracture and poor aesthetic result. Postoperative complications can be reduced by maintain mastectomy flap thickness and asses flap vascularity with near infrared imaging. The prepectoral reconstruction with polyurethane implants has been utilized with encouraging results. Postoperative patient satisfaction was assessed with the BREAST-Q scores in patients who underwent prepectoral reconstruction with polyurethane implants. Additionally the impact of mastectomy flap thickness on breast reconstruction was investigated.Materials and MethodsThe Breast Q-scores of satisfaction with the breast, the postoperative outcome and physical well-being of the chest in 70 patients underwent immediate implant breast reconstructions with prepectoral polyurethane implant were retrospectively reviewed. The correlation between mastectomy flap thickness and satisfaction with breast was analyzed.ResultsAt 12-month follow-up the mean Q-score for satisfaction with breast was 71.73 (standard deviation: 13.31), and for physical well-being chest was 70.73 (standard deviation: 7.94). A positive linear correlation between mastectomy flap thickness and satisfaction with the breast was identified.ConclusionsThe postoperative Q-scores are encouraging in the use of polyurethane prepectoral implants in immediate breast reconstruction, especially in patients with “thick” mastectomy flaps.     

Microsurgical breast reconstruction

Breast cancer, the most common cancer diagnosed in American women, often necessitates mastectomy. Many studies have demonstrated improved quality of life and well-being after breast reconstruction. Numerous techniques are available for breast reconstruction including tissue expander implants and autologous tissues. Microsurgical tissue transfer involves the use of excess skin and fat (flaps) from a remote location to reconstruct the breast. Most often, tissues are transferred from the abdomen and buttocks. Less commonly, thigh flaps are used. These operations can provide durable, esthetic reconstructions. In addition, advances in microsurgical techniques have improved operative success rates to the range of 99%. The selection of an appropriate flap for microsurgical breast reconstruction is multifactorial and is based on patient and oncologic factors. These factors include patient comorbidities, body habitus/availability of donor tissues, cancer stage, and the need for postoperative adjuvant radiation therapy, as well as the risk of cancer in the contralateral breast. Appropriate choice of flap and surgical technique can minimize the risk of operative complications. Additionally, several large series have established that microsurgical breast reconstruction has no impact on survival, or locoregional/distant recurrence rates.     

State of the Art in Breast Reconstruction

In patients undergoing breast reconstruction after partial and total mastectomy, selecting the appropriate timing as well as the best method of reconstruction are essential to optimize the outcome. At M.D. Anderson Cancer Center, the timing of oncoplastic repair after partial mastectomy defects and breast reconstruction after mastectomy tends to dictate the technique for reconstruction. In patients undergoing repair of a partial mastectomy defect, immediate or delayed repair before radiation therapy allows for the use of the remaining breast tissue to perform the repair. Delayed repair after radiation therapy is usually performed with autologous fat grafting or a flap. Immediate breast reconstruction after mastectomy is preferable for patients with a low risk of requiring postmastectomy radiation therapy (XRT) (stage I breast cancer, some stage II). In patients who are deemed preoperatively to be at an increased risk of requiring XRT (stage II breast cancer), delayed-immediate breast reconstruction may provide an additional option. Delayed-delayed reconstruction may be a consideration in patients known preoperatively to require XRT (stage III breast cancer), to allow for a skin-preserving delayed reconstruction after XRT. Newer techniques for breast reconstruction after mastectomy include one-stage implant, implant-based reconstruction plus acellular dermal matrix, autologous fat grafting after negative suction applied to chest wall, and perforator-based autologous tissue flaps. Often, the decision to perform a partial or total mastectomy depends upon reconstructive issues, not oncology-related considerations. Whether to repair a partial mastectomy defect or perform a total breast reconstruction after mastectomy is one of the most critical decisions in breast reconstruction.

Oncological aspect of immediate breast reconstruction in mastectomy patients.

In this study, we compared the relapse-free and overall survival of 83 patients who underwent mastectomy with immediate reconstruction (MIBR) using a musculocutaneous flap with or without silicone implant with those of 153 patients with breast cancer who underwent mastectomy without immediate reconstruction. In univariate analysis, the overall and/or relapse-free survival of reconstructed patients with four or more positive axillary lymph nodes or those with menopausal status were significantly inferior compared with those of nonreconstructed patients. In multivariate analysis, however, the immediate breast reconstruction did not appear to have a significant adverse influence on all patients, and on the subgroups stratified by menopausal status or axillary lymph node metastases. Therefore, it was concluded that MIBR using a musculocutaneous flap did not compromise the survival of patients with breast cancer.     

Postmastectomy radiation therapy and breast reconstruction with autologous tissue

Immediate breast reconstruction is an important tool for patients to accept and overcome their breast cancer, as well as for cosmetic reasons. However, its use in patients who require postmastectomy radiation therapy (PMRT) is not yet clear. The purpose of this study was to analyze the effects of PMRT and reconstruction on each other. The time of initiation of PMRT, the prognosis, and the cosmetic results were investigated in patients who underwent immediate reconstruction using autologous tissue. In the case of delayed reconstruction using autologous tissue after PMRT, radiation damage of the chest skin, design of the flap, and cosmetic results were investigated. In 38 patients who underwent immediate reconstruction and PMRT between 2006 and 2015, 20 patients received neoadjuvant chemotherapy, and their mean time before starting PMRT was 9.7 weeks after surgery (range 7–18 weeks). Three patients underwent delayed PMRT (more than 12 weeks) due to partial flap necrosis and wound infection. Of 28 patients (2006–2010), 23 were disease free (stage I: 2/2, stage II: 15/16, stage III: 6/10), one patient (stage III) had distant metastases, and 4 patients died of primary disease (stage II: 1/16, stage III: 3/10). Unacceptable deformation of the reconstructed breast was observed in 4 patients who had partial fat necrosis of the grafted flap or skin necrosis of the mastectomy flap. In 20 patients who underwent delayed reconstruction between 2006 and 2015, 15 (75%) patients underwent replacement of irradiated chest skin with flap skin to reconstruct a soft and natural shape breast. The flap survival rate was 100%, and unacceptable deformation of the reconstructed breast was not seen. In the case of immediate reconstruction using autologous tissue, it is important to graft a flap with a good blood supply to avoid delaying PMRT and achieving a good cosmetic result, because flap necrosis or wound infection delays PMRT and causes scar contracture after PMRT. In the case of delayed reconstruction after PMRT, chest wall skin with radiation damage should be resected and replaced by flap skin.

Immediate postmastectomy reconstruction

The role of reconstruction in the management of patients with problems related to breast cancer is of increasing importance. Immediate reconstruction is particularly applicable in those situations where prophylactic mastectomy is performed. High-risk groups who warrant such prophylactic mastectomy and reconstruction include those with florid cyst disease, a strong family history of breast cancer, the finding of lobular carcinoma in situ, multiple previous biopsies, and those who have severe and progressive mastodynia. In those with smaller amounts of breast tissue, reconstruction is based on a double layer of tissue over a graft, one layer consisting of pectoral muscle and the other of breast skin. In those with more abundant breast tissue, the two layers placed over the graft are both derived from skin flaps, the inner layer a free, denuded dermal graft from the inferior flap and the second layer, the superior breast skin flap itself.     

Skin sparing mastectomy: Technique and suggested methods of reconstruction

AimTo demonstrate the feasibility and accessibility of performing adequate mastectomy to extirpate the breast tissue, along with en-block formal axillary dissection performed from within the same incision. We also compared different methods of immediate breast reconstruction used to fill the skin envelope to achieve the best aesthetic results.Methods38 patients with breast cancer underwent skin-sparing mastectomy with formal axillary clearance, through a circum-areolar incision. Immediate breast reconstruction was performed using different techniques to fill in the skin envelope. Two reconstruction groups were assigned; group 1: Autologus tissue transfer only (n = 24), and group 2: implant augmentation (n = 14).Autologus tissue transferThe techniques used included filling in the skin envelope using Extended Latissimus Dorsi flap (18 patients) and Pedicled TRAM flap (6 patients).Augmentation with implantsSubpectoral implants(4 patients), a rounded implant placed under the pectoralis major muscle to augment an LD reconstructed breast. LD pocket (10 patients), an anatomical implant placed over the pectoralis major muscle within a pocket created by the LD flap. No contra-lateral procedure was performed in any of the cases to achieve symmetry.ResultsAll cases underwent adequate excision of the breast tissue along with en-block complete axillary clearance (when indicated), without the need for an additional axillary incision.Eighteen patients underwent reconstruction using extended LD flaps only, six had TRAM flaps, four had augmentation using implants placed below the pectoralis muscle along with LD flaps, and ten had implants placed within the LD pocket.Breast shape, volume and contour were successfully restored in all patients.Adequate degree of ptosis was achieved, to ensure maximal symmetry.ConclusionsSkin Sparing mastectomy through a circum-areolar incision has proven to be a safe and feasible option for the management of breast cancer in Egyptian women, offering them adequate oncologic control and optimum cosmetic outcome through preservation of the skin envelope of the breast when ever indicated. Our patients can benefit from safe surgery and have good cosmetic outcomeby applying different reconstructive techniques.

Options for immediate breast reconstruction following skin-sparing mastectomy.

BACKGROUND: Skin-sparing mastectomy (SSM) is a type of breast cancer surgery presupposed as breast reconstruction surgery. Cosmetically, it is an extremely effective breast cancer operation because the greater part of the breast's native skin and infra-mammary fold are conserved. All cases of SSM and immediate breast reconstruction performed by the senior author during the last five years were reviewed. METHODS: There are three implant options for breast reconstruction, namely, deep inferior epigastric perforator (DIEP) flap, latissimus dorsi myocutaneous (LDM) flap, and breast implant, and one of these was used for reconstruction after comprehensive evaluation. RESULTS: From 2001 to 2005, immediate reconstructions following SSM were performed on 124 cases (128 breasts) by the same surgeon. Partial necrosis of the breast skin occurred in 4 cases of SSM. The mean follow-up was 33.6 months. During the follow-up, there was local recurrence following surgery in 3 cases. The overall aesthetic results of immediate breast reconstruction after SSM are better than those after non-SSM. CONCLUSION: SSM preserves the native breast skin and infra-mammary fold, and is an extremely useful breast cancer surgery for breast reconstruction. SSM is an excellent breast cancer surgical technique. We think this procedure should be considered in more facilities conducting breast reconstruction in Japan.     

Post-Mastectomy Breast Reconstruction: A History in Evolution

Although the need for mastectomy has been evident for many years, postmastectomy reconstruction has been recognized as an achievable outcome for only a little over a century. A review of the evolution of both autologous and prosthetic options for reconstruction was undertaken. The earliest attempts at reconstruction used autologous techniques that were either unsuccessful, not reproducible, or were associated with significant morbidity. Prosthetic techniques became sought after, with silicone prostheses widely used until concerns about potential adverse effects led to the investigation of alternate options. With these concerns shown to be unfounded, silicone and saline prostheses evolved with successive generations of implants. Concurrent advances in reconstructive surgery led to a revival in autologous techniques for breast reconstruction, with microsurgical free-tissue transfer potentiating a new range of potential donor sites. The abdominal wall became the donor site of choice, and with the advent of perforator flaps, morbidity associated with flap harvest was minimized. In cases where the abdominal wall is unsuitable, flaps such as the superior and inferior gluteal artery perforator flaps, the musculocutaneous gracilis flap, and the “stacked” deep inferior epigastric artery perforator flap are frequently used options. The development of minimally invasive techniques for implant placement and flap harvest, such as endoscopy, continue to evolve, and research in tissue engineering offers a vision for a future without the need for a donor site.

Breast reconstruction with the TRAM flap: pedicled and free

BACKGROUND: Breast cancer is a ubiquitous disease affecting one in seven women. While breast conservation techniques are available for local control of the disease for many patients, not all patients are good candidates for these techniques. Mastectomy, therefore, remains a common method of breast cancer treatment. Methods of reconstruction include implant reconstruction and autogenous reconstruction. The advantages of autogenous reconstruction include the creation of a soft, ptotic breast mound, which tends to match a native contralateral breast both in and out of bra support. Autogenous reconstructions do not tend to change with time and usually do not require periodic revision as seen in implant reconstructions. METHODS: The most common method of autogenous reconstruction is the TRAM flap, either pedicled or free. The TRAM flap employs the redundant excess lower abdominal tissue typically removed during a cosmetic abdominoplasty. This tissue is brought to the mastectomy defect as a pedicled flap, passing subcutaneously from the upper abdomen and into the defect site. The pedicled flap is based upon the superior epigastric vessels. A free TRAM is harvested with the overlying muscle and the attached inferior epigastric vessels. This flap is completely separated from the abdomen and brought to the chest defect where it is anastomosed to either the thoracodorsal or internal mammary vessels. The donor defect within the abdominal wall is repaired with an inlay mesh with both the pedicled and free techniques. RESULTS: Patient selection criteria usually help determine which technique is used. The advantage of the free flap technique is improved blood supply to the skin island. The free flap, therefore, is used in patients at higher risk for partial flap loss with the pedicled technique. Such high-risk patients include smokers, the obese, patients with significant medical comorbidities, and patients with prior abdominal surgery. Patients without these risk factors can be expected to achieve good results with either the pedicled or free flap technique. CONCLUSION: Autogenous breast reconstruction with the TRAM flap achieves long lasting satisfactory results in most patients with the creation of a soft, naturally ptotic breast mound, which typically matches well a contralateral native breast.
