PLASTIC SURGERY THE EVER-EVOLVING FIELD of Breast Cancer Reconstruction Brad Wilhelmi, MD B reast cancer reconstruction is an extremely emotional topic by virtue of its anatomic location and the importance of the female breast in today’s society. Breast reconstruction continues to be popular as it provides mastectomy patients the oppor- tunity to be whole again, through breast mound creation with implants or flaps. The treatment algorithm is complex and individualized specifically to patients depending on their adjuvant treatments, job demands and aesthetic expecta- tions. Only through a close alliance between the surgical oncolo- gist and plastic surgeon can the patient’s emotional, physical and oncologic needs be addressed. To know where the field of breast reconstruction is progressing, it is valuable to know its origin and progression. In the 1800s, the prognosis of patients with breast cancer was poor, with local recurrence rates ranging from 50-85 percent. Eventually, Dr. William Halsted presented his advance with rad- ical mastectomy producing only six percent recurrence rates. He believed that “the slightest inattention to detail and/or attempts to hasten convalescence by such plastic operations as are feasible only when a restricted amount of skin is removed may sacrifice his patient to the disease.” This aggressive approach based on the Halstedian Theory of breast cancer treatment, would remain the mainstay of breast cancer surgery for the next 50 years. Therefore, true attempts at breast cancer reconstruction would have to wait for almost 50 years. Breast reconstruction for defects other than cancer were in- troduced over the years. In 1895, Vincenz Czerny autotransplant- ed a large lipoma from his patient’s flank to a breast defect after fibrocystic mass resection. Iginio Tansini described the first use of the latissimus dorsi myocutaneous flap (LDM) in 1906. Unfor- tunately, this remarkable operation would not gain acceptance for another 70 years. In 1942, Sir Harold Gillies of England started using tubed 24 LOUISVILLE MEDICINE pedicle technique for breast reconstruction. In this operation he would “waltz a flap from the abdomen to the chest to reconstruct the breast.” Although this technique was successful, the multiple procedures and prolonged treatment course precluded its wide- spread application. Since 1970, many advances in reconstructive surgery have occurred and been applied to breast reconstruction. The devel- opment of breast implants was the first of these revolutions. In 1963, the silicone breast implant was introduced for breast aug- mentation and quickly adopted for breast reconstruction. In 1963, Thomas Cronin and Frank Gerow presented a series of patients who received implants for reconstruction of mastectomy defects. For the first time, the plastic surgeon had a procedure that could simulate the missing breast without the need for multiple pro- cedures and a prolonged treatment course. In many ways, it was the simplicity and safety of breast implants that ignited interest in breast reconstruction. By the late 1970s, reconstruction was being performed immediately after breast ablation. The development of muscle, musculocutaneous and fasciocu- taneous flaps and microsurgical transplantation has had a tremen- dous impact on breast reconstruction. The ideal material to recon- struct any defect is like-tissue. Until the early 1970s, such tissue was only available in limited quantities for breast reconstruction. The landmark work by Carl Manchot on vascular territories of the body was rediscovered, and surgeons were then able to exploit the basic knowledge to design flaps based on axial pattern of named blood vessels. These technical developments allowed surgeons to reliably rearrange tissues and more precisely reconstruct all types of defects including those of the breast. These advances paved the way for flap developments and refinements including the LDM flap from the back, the TRAM flap from the abdomen, the SGAP flap from the buttock, the TUG flap from the medial thigh, and the Rubens flap from the upper hip. These flaps have the advantage of providing like-tissue, however at a cost of donor site scarring and potential weakness. Therefore, implants have continued to be the primary choice of patients for breast reconstruction over the years.
