One of every eight women in the United States develops breast cancer in her lifetime.1 As a result, roughly 2.5 million women in the U.S. are survivors of breast cancer, and this number is expected to increase dramatically over the next decade.1

In women with breast cancer, the selection of the initial surgical procedure is influenced by the cancer’s stage at the time of diagnosis. With early stage cancer, nearly 58% of women undergo breast-conserving surgery, and 36% undergo mastectomy. With more advanced breast cancer, if surgery is performed, mastectomy is carried out in 58% of patients, and breast-conserving therapy is used in 14%.2 Thus, mastectomy continues to play a major role in the treatment of breast cancer, and in most cases, offers the chance for longterm survival. In addition to women who undergo mastectomy, a substantial percentage of those who have breast conservation therapy are unhappy with their ultimate cosmetic result.3

There are also other reasons for an increasing need for reconstruction. With the advent of risk stratification by genetic testing for BRCA1 and BRCA2, an increasing number of women are electing prophylactic mastectomy. Also, the frequency of contralateral prophylactic mastectomy is increasing dramatically in patients who undergo mastectomy for unilateral disease.4, 5 Thus, studies over the past 20 years have shown a distinct trend toward increased use of contralateral and bilateral prophylactic mastectomy.6

The mastectomy defect can be devastating both physically and psychologically, and numerous studies have documented a significant improvement in self-confidence and mental health following breast reconstruction.7,8,9 Reported rates of reconstruction vary widely, but a study in two major American cities reported that 42% of mastectomy patients underwent reconstruction.10 As reported by the American Society of Plastic Surgeons, in 2015 over 100,000 patients received breast reconstruction, a 35% increase since 2000. Although less than 20% of these cases were autologous free flap procedures, these operations are more prevalent at high volume breast reconstruction centers, such as the University of Pennsylvania.

The public’s awareness of this option must still be improved, as only 23% of women know the wide range of available options for breast reconstruction.10

Options for reconstruction include alloplastic techniques, such as insertion of a tissue expander/implant, or autologous reconstruction with free flaps. Alloplastic techniques have been more commonly utilized nationally as they avoid the need for technically challenging microsurgery. A recent study by our institution demonstrated that although there was a lower complication profile for alloplastic reconstructions, they were followed by  higher rates of secondary breast procedures.11 Additionally, we have shown a higher two-year success rate using free flap reconstruction, a significantly lower rate of unplanned surgical revisions, and lower cost.12

Importantly, no single procedure is favored in all circumstances, and patients clearly benefit from individual selection of the best procedure. Patients who see a plastic surgeon are now often well informed about their options in advance. The discussion between surgeon and patient about an overall plan for reconstruction must be an open dialogue that involves both listening and education.

Autologous Reconstruction
Perhaps the most monumental contribution to autologous breast reconstruction was the introduction of the pedicled transverse rectus abdominis myocutaneous (TRAM) flap procedure by Hartrampf et al. in 1982.13 This technique remains the most common method of autologous breast reconstruction. Though free tissue transfer for breast reconstruction was first reported by Fujino et al. in 1976, the technique did not become popular in the United states until the 1980s and 1990s.14 Subsequently, use of free tissue transfer has increased because of greater familiarity with microvascular techniques. Examples of these approaches include the free TRAM flap, the deep inferior epigastric perforator (DIEP) flap, and the superficial inferior epigastric artery (SIEA) flap.

Although these autologous approaches remain less common than alloplastic reconstructions, using a patient’s own tissue has some distinct advantages. Autologous reconstruction has the benefit of replacing “like with like,” which in turn contributes to an improved feeling of restoration of the self after mastectomy.15 Methods of using abdominal donation have the added benefit of the concomitant abdominoplasty, which many women find appealing. The disadvantage is the rare possibility of catastrophic complete loss of the flap, necessitating further surgery. Our institution has previously published a 2% take-back rate in an analysis of 2260 total free flaps reviewed.16 In addition, autologous reconstruction is a more involved operation, with longer recovery time and potential for donor-site morbidity.

After mastectomy, autologous reconstruction can be safely performed either immediately or in a delayed fashion. Immediate reconstruction has several advantages, since patients benefit from needing only one operation and most surgeons find immediate reconstruction easier to perform due to the predictable mastectomy skin flap envelope. Precise planning of the location of the skin island can be designed on the abdomen before transfer, thus improving the efficiency and precision of the operation. Delayed reconstruction requires reevaluation of the skin flaps, which are often scarred and less compliant. The mastectomy scar should be excised completely as scarred or irradiated skin can result in inadequate breast ptosis and poor symmetry over time. Fig. 1 demonstrates the standard TRAM flap design, while Fig. 2 depicts a pre and post-operative photograph of a patient undergoing unilateral reconstruction. When reattachment of vessels is appropriate, the tissue can be transferred as a free flap with anastomosis to the internal mammary artery. Alternatively, the tissue can be pedicled, leaving the vasculature attached and rotating the tissue up from the abdomen. A pedicled TRAM flap rotates along a tissue axis connected to the flap’s blood supply, and is placed into the correct position on the chest wall.

Nipple-Areola Complex Reconstruction
After reconstruction of the breast mound, many women opt to have the nipple-areola complex recreated as a final step in restoring body image. There are many available techniques, including grafts from skin, buccal mucosa, labia minora or majora, thigh, buttocks, groin, upper eyelids, or earlobes. Although the technique varies, the principles remain the same: to provide color, texture, size, and projection that are all in line with the patient’s aesthetic wishes. Many of the earlier methods suffered from loss of projection over time and difficulty with color matching and stability. The most common method used today consists of local skin flap rearrangement to create texture and projection followed by tattooing for color (Fig. 3). Nipple-areola complex (NAC) reconstruction is usually performed more than 3 to 4 months after mound reconstruction. This allows for complete healing of the flap, and ensures breast symmetry, an important prerequisite before recreating a NAC.

(Right) This patient had a similar presentation and operative intervention. She has completed the tattooing process for color. Penn Plastic Surgery photos.

Nerve Coaptation
Restoration of breast sensation following breast reconstruction is an evolving part of the reconstruction paradigm. Although spontaneous recovery of sensation has been reported following mastectomy, surgeons are advocating innervated reconstruction using neurotization at the time of autologous reconstruction. This technique dates back to the early 1990s, but has yet to be rigorously tested in a large prospective randomized control trial. Fig. 4 demonstrates the graft and nerve coaptation connecting the transferred abdominal tissue to the chest wall. Restoring sensation to the reconstructed breast via nerve coaptation is an invaluable adjunctive procedure on the cutting edge of breast reconstruction.

In unilateral reconstruction, patients will need to continue routine mammography of the contralateral breast. Because of the possibility of recurrence, patients should be instructed to continue self-examination of the reconstructed breast. Mammography of the reconstructed mound has been shown to be less sensitive for detecting malignant lesions when compared with the native breast. Nonetheless, there have been reports of calcifications being detected by mammography, allowing diagnosis of a recurrence that was not palpable.17,18,19 Currently, however, routine mammography of the reconstructed breast mound is not considered standard of care.

Breast reconstruction is becoming increasingly popular and is important to many women following treatment of breast cancer. There are many options available to the patient, but ultimately which technique is used should be based on surgeon familiarity, hospital resources, and the patient’s wishes. All can be offered with a high degree of patient satisfaction and a low rate of complications.
