Progress in the surgical management of breast cancer: Present and future

Published Online: August 03, 2015

 

Recognition of differing risks of locoregional recurrence (LRR) in breast cancer patients based on estrogen receptor, progesterone receptor, and HER2 status, coupled with a reduction in LRR in patients receiving adjuvant systemic therapy, offers the opportunity to tailor surgical treatment and reduce the morbidity of therapy. New guidelines for margins in breast-conserving therapy of tumor not touching ink and avoidance of axillary dissection in sentinel node positive patients undergoing breast-conserving therapy are examples of this approach which have entered practice.

Embrace the Change: IncorporatingSingle-Stage Implant Breast Reconstruction into Your Practice

Plastic & Reconstructive Surgery: August 2015 - Volume 136 - Issue 2 - p 221–231

Background: Multiple studies have reported on the safety of nipple-sparing mastectomy and low complication rates associated with single-stage implant breast reconstruction. Yet many plastic surgeons continue to be resistant to change. This article presents the senior author’s (M.A.C.) experience during his transition period from the latissimus dorsi flap with adjustable implants to a “one-and-done” approach using shaped implants and fetal bovine acellular dermal matrix. Methods: A literature review was performed selecting articles discussing single-stage implant reconstruction, indications, outcomes, technique, and complications. Additional articles were selected after review of the references of identified articles. Clinical pearls discussed include patient selection, implant selection, and mastectomy incision choices, with a detailed description of the senior author’s operative technique. Results: Twenty-seven single-stage implant reconstructions were performed. Average mastectomy weight was 343.82 g. The average implant volume was 367 cc. Shaped implants were most commonly used. Acellular dermal matrix was used in all breasts. Complications included erythema requiring intravenous antibiotics (three patients), skin ischemia caused by methylene blue (one patient), seroma (one patient), unilateral partial nipple necrosis (one patient), mastectomy skin necrosis (one patient), and exposed/infected implants that were salvaged using a sequential irrigation protocol described by Sforza et al. in 2014 (two patients). Conclusions: Breast reconstruction after mastectomy has evolved toward less invasive, single-stage procedures. Aesthetic refinements include nipple-sparing mastectomy, use of acellular dermal matrix, shaped implants, and fat grafting. Selected patients will benefit from a one-and-done breast implant reconstruction with no additional oncologic risk. Surgeons must embrace the change and provide their patients with a procedure that will offer the best aesthetic outcomes. 

Breast Implant–Associated Anaplastic Large Cell Lymphoma: Proposal for a Monitoring Protocol

Breast Implant–AssociatedAnaplastic Large Cell Lymphoma: Proposal for a Monitoring Protocol

Plastic & Reconstructive Surgery: August 2015 - Volume 136 - Issue 2 - p 144e–151e

Background: The authors report four cases of breast implant–associated anaplastic large cell lymphoma (ALCL) from a single institution and propose a multidisciplinary protocol. Methods: From 2012 to 2014, four breast implant–associated ALCL cases were diagnosed. The authors performed the original operation, and no patients were referred to their practice. Cases 1, 2, and 4 were CD4+/CD30+/ALK− ALCL with previous textured-implant reconstruction, whereas case 3 was CD8+/CD30+/ALK− ALCL with previous polyurethane-implant augmentation. A retrospective study of all patients who underwent breast implant positioning was performed to identify any misdiagnosed cases. Results: Of 483 patients, 226 underwent reconstruction with latissimus dorsi flap and prosthesis, 115 had skin-sparing/nipple-sparing mastectomy and prosthesis, 117 underwent an expander/implant procedure, and 25 underwent breast augmentation. Fifty-eight cases (12 percent) underwent implant replacement for capsular contracture, 15 (3.1 percent) experienced late-onset seroma, and four (0.83 percent) had both capsular contracture and seroma. Seventy-seven symptomatic patients (16 percent) underwent surgical revision (capsulectomy/capsulotomy) and/or seroma evacuation. The second look on histologic specimens did not identify misdiagnosed cases. A multidisciplinary protocol for suspected implant-associated ALCL was established. Ultrasound and cytologic examinations are performed in case of periprosthetic effusion. If implant-associated ALCL is diagnosed, implant removal with capsulectomy is performed. If disseminated disease is detected through positron emission tomography/computed tomography of the total body, the patient is referred to the oncology department. Conclusions: A multidisciplinary protocol is mandatory for both early diagnosis and patient management. Until definitive data emerge regarding the exact etiopathogenesis of breast implant–associated ALCL, the authors suggest offering only autologous reconstruction if patients desire it. 

Regional Nodal Irradiation in Early-Stage Breast Cancer

N Engl J Med 2015; 373:317-327 July 23, 2015

BACKGROUND

Most women with breast cancer who undergo breast-conserving surgery receive whole-breast irradiation. We examined whether the addition of regional nodal irradiation to whole-breast irradiation improved outcomes.

Patterns and Trends in Immediate Postmastectomy Reconstruction in California: Complications and Unscheduled Readmissions

Patterns and Trends in Immediate Postmastectomy Reconstruction in California: Complications and UnscheduledReadmissions

Plastic & Reconstructive Surgery: July 2015 - Volume 136 - Issue 1 - p 10e–19e

Background: Immediate reconstruction rates after mastectomy are increasing but remain low. Little is known about hospital readmissions after these procedures. The authors studied unscheduled readmissions after immediate reconstruction. Methods: Using the Healthcare Cost and Utilization Project California State database, the authors identified patients undergoing mastectomy only or with immediate reconstruction for ductal carcinoma in situ and invasive breast cancer from 2005 to 2009. Immediate reconstruction included tissue expander/implant and autologous tissue reconstructions. The authors evaluated temporal trends in immediate reconstruction and factors associated with 30-day unscheduled readmissions after reconstruction. Results: The cohort contained 48,414 patients (mastectomy only, 35,648; immediate reconstruction, 12,766; tissue expander/implant, 10,437; autologous tissue, 2329). Readmission rates were not significantly different between mastectomy only and immediate reconstruction (3.55 percent versus 3.39 percent; p = 0.39); however, autologous tissue reconstruction was associated with a significantly higher readmission rate compared with tissue expander/implant reconstruction (4.08 percent versus 3.24 percent; p = 0.04). Conclusions: Immediate reconstruction does not result in higher readmission rates compared with mastectomy only. All women undergoing mastectomy should be offered consultation for reconstruction.

Challenges in optimizing care in advanced breast cancer patients: Results of an international survey linked to the ABC1 consensus conference

Challenges in optimizing care in advanced breast cancer patients: Results of an international survey linked to the ABC1consensus conference

Published Online: July 19, 2015

Until recently, many international guidelines have focussed on the treatment of early-stage breast cancer, with little emphasis on advanced-stage disease. To improve the management of advanced breast cancer (ABC), the European School of Oncology (ESO) established the ABC International Consensus Conference and Guidelines. Delegates from the first conference and additional groups selected by ESO were invited to complete a survey to identify current challenges and barriers associated with optimizing ABC management.

Surgical margin reporting in breast conserving surgery: Does compliance with guidelines affect re-excision and mastectomy rates?

Published Online: July 18, 2015

Margin status is important in guiding decisions to re-excise following breast-conserving surgery (BCS) for breast cancer. The College of American Pathologists (CAP) developed guidelines to standardize pathology reporting; however, compliance with margin documentation guidelines has been shown to vary. The aim of this retrospective study was to determine whether compliance with CAP guidelines affects re-excision and mastectomy rates.

Potential of overcoming resistance to HER2-targeted therapies through the PI3K/Akt/mTOR pathway

Potential of overcoming resistance to HER2-targeted therapies through the PI3K/Akt/mTORpathway

Human epidermal growth factor receptor 2 (HER2) overexpression occurs in up to 30% of breast cancers and is a marker of aggressive disease. While HER2-targeted therapies have improved outcomes in these tumors, resistance to these agents develops in a large proportion of patients. Determining molecular mechanisms underlying resistance might help improve outcomes for patients with HER2-positive disease by allowing development of strategies to overcome resistance. Activation of signaling pathways involving the phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) pathway might contribute to the development of resistance to HER2-targeted therapies.
