Oncoplastic Breast Surgery

Breast Surgery is now a recognized subspecialty of General Surgery abroad with structured training for designated ‘Oncoplastic Breast Surgeons’. Oncoplastic Breast surgery is probably one of the most interesting and challenging new developments over the past 20 years. The aims of Oncoplastic surgery are wide local excision of the cancer coupled with partial reconstruction of the defect to achieve a cosmetically acceptable result. Avoidance of mastectomy and consequent reduction of psychological morbidity are the principal goals in the development of various oncoplastic techniques. The use of plastic surgical techniques not only ensures good cosmetic outcome, but also allows the cancer surgeon to remove the tumour with greater volume of surrounding tissue, thus extending the boundaries of breast conserving surgery. Proper patient selection and careful planning after proper radiological and clinical assessment are the two essential prerequisites before undertaking oncoplastic breast surgery. Oncoplastic surgery involves both volume displacement and volume replacement techniques. Some commonly used volume displacement procedures are described in the article. The need for adjustment of contralateral breast should also be anticipated at the time of planning breast conserving surgery, which can be done either at the same time as breast cancer surgery or as a delayed setting.     

Long-Term Comparison of Aesthetical Outcomes After Oncoplastic Surgery and Lumpectomy in Breast Cancer Patients

Periareolar Approach in Oncoplastic Breast Conservative Surgery

Breast cancer represents the most frequent cancer in female population. Nowadays breast conservative surgery (BCS) is an accepted option for breast malignancies, and its indications has been extended thanks to the advent of oncoplastic surgery, reducing both mastectomy and re‐excision rate, avoiding at the same time breast deformities. From January 2008 to November 2011, 84 women underwent BCS with periareolar approach for oncoplastic volume replacement. We divided patients into four groups analyzing breast size and resection volume (Group 1: small‐moderate sized breast with resection <20%; Group 2: small‐moderate sized breast with resection >20%; Group 3: big sized breast with resection <20%; Group 4: big sized breast with resection >20%). We evaluated patients’ satisfaction regarding final esthetic outcome using the specific module “Satisfaction with outcome” of the Breast‐Q questionnaire 1 year after surgery. The mean age was 52.1 years, and the mean follow‐up was 11.2 months. During the follow‐up, 12 patients have been lost. We obtained high satisfaction mean value with Breast‐Q questionnaire in each group: 75.8 in group 1, 63.4 in group 2, 81.1 in group 3, 69.7 in group 4. Periareolar approach as oncoplastic volume replacement technique is useful in correction of breast deformity after BCS: it is a versatile technique that can be easily adapted for any breast tumor location and for wide glandular resection.     

The Role of Oncoplastic Surgery in Breast Cancer

The authors discuss the objectives of oncoplastic surgery in breast cancer management. Indications and advantages are summarised. Some surgical techniques are described.

The authors report their own experience with oncoplastic surgery (26 patients who had immediate breast reconstruction after tumorectomy, and 126 patients who had lumpectomy alone. Oncoplastic surgery was characterised by a wider excision, with negative margins in all cases. In isolated breast conservative tumorectomy, 20% of the margins were positive, requiring re-excision or radical mastectomy.

Oncoplastic surgery is preferred especially in younger patients with smaller breasts, since it is less cosmetically mutulating and allows complete tumor resection with save margins.     

Basic Oncoplastic Surgery for Breast Conservation: Tips and Techniques

Background

The demand for oncoplastic breast surgery has increased significantly in recent years. However, these procedures are often not taught in standard training for breast surgeons, and a simple guide for surgeons to start performing basic oncoplastic breast surgery techniques is not available.

Methods

The basic concepts of oncoplastic breast surgery and the tools needed prior to starting these types of procedures are discussed, and the procedure, in a stepwise pattern, for the building blocks of oncoplastic techniques is outlined.

Results

The importance of oncoplastics from a quality of life and oncologic standpoint are described. Key concepts are defined and the decision on when it is necessary to consult reconstructive plastic surgery is delineated. The basic necessities for oncoplastic breast surgery, including patient photographs, important intraoperative tools, anatomic knowledge, and patient selection, are discussed. The building block procedures include aesthetic scar placement, parenchymal closure, deepithelialization, and donut therapeutic mastopexy, which are described in detail.

Conclusions

Oncoplastic breast surgery techniques and clinical reasoning build on one another, allowing a surgeon to move from level I to level II oncoplastic procedures. Even the most basic level I breast conservation oncoplastic skills can improve a patient’s cosmetic outcome and are easily learned by a general surgeon.

Cosmetic Outcome and Percentage of Breast Volume Excision in Oncoplastic Breast Conserving Surgery

Background  

Since breast-conserving surgery demonstrated identical long term survival on seven randomized trials, it has become the preferred treatment option over mastectomy. Oncoplastic surgery applying simple reshaping and displacement techniques allows inclusion of patients with large tumors in the group selected for breast-conserving surgery. However, the cosmetic outcome and the degree of patient satisfaction, especially in relation to the original breast volume and the percentage of breast tissue excised is not well documented.     

Improving Breast Cancer Surgery: A Classification and Quadrant per Quadrant Atlas for Oncoplastic Surgery

Background  

Oncoplastic surgery (OPS) has emerged as a new approach for extending breast conserving surgery (BCS) possibilities, reducing both mastectomy and re-excision rates, while avoiding breast deformities. OPS is based upon the integration of plastic surgery techniques for immediate reshaping after wide excision for breast cancer. A simple guide for choosing the appropriate OPS procedure is not available.     

Comparative Study of the Accuracy of Breast Resection in Oncoplastic Surgery and Quadrantectomy in Breast Cancer

Background The aim of this study was to determine whether oncoplastic surgery ensures accurate tumor resection and reduces the need for further surgery in comparison with standard quadrantectomies. Methods This was a prospective comparative study of 74 patients with breast tumor diameter ≥15 mm. The principal criterion for case selection was breast size that allowed either quadrantectomy or oncoplastic surgery to be scheduled. The following were recorded and compared between groups: the size of the glandular resection, the width of the nearest margins, the ratio of clear margins, and the need for further surgery. Results The patients who underwent oncoplastic surgery were younger than those who had quadrantectomy. All other demographic and oncological preoperative data were comparable. The median volume of the excised specimen in the oncoplastic group was higher than in the quadrantectomy group. The nearest lateral margin widths were larger in the oncoplastic group than in the quadrantectomy group. Free surgical margins ≥5 mm and ≥10 mm were obtained more frequently using oncoplastic surgery than standard quadrantectomy. However, the need for fewer secondary surgeries was not demonstrated in our study. Conclusions Oncoplastic surgery achieves more accurate tumor resection than standard quadrantectomy. This approach might be useful in extending the indications for conservative therapy.     

Level 2 Oncoplastic Surgery for Lower Inner Quadrant Breast Cancers: The LIQ-V Mammoplasty

Background

Oncoplastic surgical techniques offer an option of breast conserving surgery for larger tumors with the use of glandular reshaping to prevent postoperative deformity. A technique for the excision of lower inner quadrant tumors via a V incision is described, the lower-inner quadrant-V (LIQ-V) mammoplasty, and the results of a pilot study are reported.

Methods

Retrospective collection of pre- and postoperative data was collected from patients undergoing a LIQ-V mammoplasty for a LIQ tumor.

Results

Twenty-two patients were operated on between 2004 and 2011 at a mean age of 58 years. The mean follow-up was 55 months. The mean resection weight was 101 g for tumors ranging in size from 4 to 31 mm. The margins were clear in 95 % of cases. There was one case of local recurrence and metastatic disease. The cosmetic outcome was judged as excellent in 68 % of cases, and no patient required further ipsilateral or contralateral symmetrizing surgery.

Discussion

The deformity often associated with tumors of the LIQ is adequately addressed by this new technique. It has a complication rate comparable to other mammoplasty series and a high rate of clear resection margins. Many oncoplastic surgery techniques are based on inverted T mammoplasty, but these are not suited for all tumor locations. The LIQ-V mammoplasty is an adaptation of the standard techniques that best suit the LIQ. It is oncologically safe and provides disease-free margins, and although the resection volumes are large, the cosmetic outcome is not compromised.     

The Integrated Evaluation of the Results of Oncoplastic Surgery for Locally Advanced Breast Cancer

The optimal surgical management of locally advanced breast cancer (LABC) remains undefined. The aim of the study was to obtain long‐term results of oncoplastic surgery in terms of overall survival, loco‐regional recurrence, and quality of life in case of LABC. Prospective cohort study enrolled 60 patients with stage III breast cancer. Forty‐two (70%) patients received neo‐adjuvant chemotherapy, 28 patients were considered suitable for surgery as initial treatment option. Type II oncoplastic surgery was performed for all patients: hemimastectomy and breast reconstruction with latissimus dorsi flap – for 29 (48.3%), lumpectomy – 31 (51.7%), and reconstruction with subaxillary flap for four (6.7%), with bilateral reduction mammoplasty – 14 (23.3%) and with J‐plastic – 13 (21.7%) patients. Adjuvant chemotherapy and hormonal therapy followed surgery for all, except one, patients. Sequential radiotherapy was administered for all patients. The mean period of follow‐up was 86 months. Postoperative morbidity rate was 5%. Local‐regional recurrence was detected in six (10%) patients. After reoperation no local relapse was diagnosed. However, three of these patients had systemic dissemination of the disease. Distant metastasis was detected in 23 (38.3%) patients. Distant metastasis‐free survival at 5 years was 61.7%. Fourteen patients died (23.3%). A total of 87.2% of the patients had good and excellent esthetic outcome. Oncoplastic breast‐conserving surgery can be proposed for selected patients with LABC with acceptable complication, local recurrence rate, and good esthetic results.     

Comparative Study of Surgical Margins in Oncoplastic Surgery and Quadrantectomy in Breast Cancer

Background Oncoplastic surgery for breast cancer is a novel concept that combines a plastic surgical procedure with breast-conserving treatment to improve the final cosmetic results. The aim of this study was to evaluate the oncological safety of oncoplastic procedures by studying the status of the surgical margins of the excised tumor specimen in comparison with standard quadrantectomies.Methods Thirty consecutive breast cancer patients undergoing oncoplastic surgery (group 1) and 30 patients undergoing standard quadrantectomy (group 2) were prospectively studied with regard to the stage of breast cancer, the surgical procedures performed, the volume of breast tissue excised, and the histopathology of the tumor specimen, with specific details on surgical margins.Results Patients who underwent oncoplastic surgery (group 1) were younger (mean age, 48.73 years) than patients who had a classic quadrantectomy (group 2; mean age, 55.76 years; P = .022). The mean volume of the excised specimen in group 1 was 200.18 cm³, compared with 117.55 cm³ in group 2 (P = .016). Surgical margins were negative in 25 cases out of 30 in group 1 and 17 out of 30 in group 2 (P = .05). The average length of the surgical margin was 8.5 mm in group 1 and 6.5 mm in group 2, but the difference was not statistically significant (P = .074).Conclusions Oncoplastic surgery adds to the oncological safety of breast-conserving treatment because a larger volume of breast tissue can be excised and a wider negative margin can be obtained. It is especially indicated for large tumors, for which standard breast-conserving treatment has a high probability of leaving positive margins.
