Oncoplastic Breast Conservation for Central Tumors: Definition, Classification, and the Analysis of Single Institution Experience.

Tumors in the central part of the breast are usually considered more aggressive and technically difficult, which limits breast conservation. The definition of central tumors from a surgical point of view, classification of the techniques for partial breast reconstruction, and conceptual algorithm of choice based on tumor and breast characteristics are proposed, along with the estimation of surgical and oncological safety. This is a retrospective analysis of the single-institution experience, with a focus on the decision-making process for choosing the oncoplastic breast-conserving surgery technique. To evaluate the safety of breast conservation for central tumors, a comparative analysis of early surgical complications and oncological long-term results of treatment in patients with central breast tumor location and other breast tumor locations was performed. A total of 940 lumpectomies were performed in 926 patients during 15 years. The central breast tumor location group included 128 patients with 130 lumpectomies (13.8%), and the other breast tumor locations group included 798 patients with 810 lumpectomies (86.2%). We did not find any significant differences in the rate of early surgical complications and involved margins, local and systemic recurrence rates, time to progression, or overall survival between the groups. Oncoplastic breast-conserving surgery is a safe procedure for the treatment of central tumors. In our opinion, the proposed classification of partial breast reconstruction techniques and an algorithm of their choice allow for effective restoration of the breast shape and volume according to the parameters of the tumor, breast, surgeon, and patient preferences.

A revised modified LICAP flap as a novel oncoplastic breast-conserving surgery technique for Mammary Paget’s disease

Mammary Paget’s disease is a rare form of breast cancer that presents a unique challenge to surgeons for patients who opt for breast-conserving surgery. Due to oncoplastic techniques, the options for breast-conserving surgery have diversified and allow for improved cosmetic outcomes. We present a 68-year-old lady with Mammary Paget’s disease who underwent a modified lateral intercostal artery perforator flap with a skin paddle to reconstruct the new areolar region. With this technique, we achieved complete oncological resection with excellent cosmetic outcome.

Level-2 Oncoplastic Surgical Techniques for Breast Cancer: A Preliminary Vietnamese Report.

Breast cancer is the most common malignancy and remains the first cause of death related to cancer among Vietnamese women, with an incidence of 21,555 cases in 2020. Most breast cancer patients present with invasive disease and relatively large tumor sizes. While oncoplastic surgery (OPS) are commonly applied in Western countries, data on Asian population remains relatively limited. This study aims to assess the outcomes of level-2 oncoplastic techniques in breast-conserving surgeries at the Vietnam National Cancer Hospital. From January 2017 to June 2021, a cohort of 257 breast cancer patients who underwent breast-conserving surgery with OPS techniques were examined. Surgical complications, cosmetic outcome, recurrence and survival rates were assessed. The mean age was 47.6±9.4 years, most patients had breast cup sizes B and C. The mean tumor size upon pathological examination was 2.00 ± 0.74 cm. Only 7 cases required reoperation, resulting in a mastectomy rate of 1.17%. The overall complication rate was low at 11.46%, with 9 cases (3.56%) experiencing delayed complications. Cosmetic results were rated as "excellent" in 20.6% and "good" in 60.5%, with a statistically significant difference. The rates of local recurrence, regional recurrence, and distant metastasis at five years were 2.78%, 1.19%, and 2.36%, respectively. The level 2 oncoplastic techniques had low complication rates, favorable oncological outcomes, and cosmetically satisfying results.

Does oncoplastic breast-conserving surgery cause unnecessary additional evaluations?

Patients who have undergone breast-conserving surgery may experience fear of recurrence. Post-operative granulation tissue and fat necrosis are common issues for these patients. As a result, additional examinations may increase, which can entail increased costs and stress for patients. In this study, if oncoplastic breast-conserving surgery causes additional imaging and unnecessary additional evaluations. We retrospectively analyzed data from 432 patients who had undergone breast-conserving surgery in the same surgical unit between 2013 and 2017. We separated the patients into two main groups: Group 1 were those operated with conservative breast-conserving surgery, while Group 2 had operations using oncoplastic breast-conserving surgery techniques. The two groups were compared in terms of post-operative radiological examinations, suspected radiological findings, and biopsy needs. There were 203 patients in Group 1 and 229 in Group 2. The median follow-up time was 66 months (range 12-109). Additional mammography use was higher in the second group (p=0.003). However, the two groups had no statistical differences for additional imaging and biopsy needs in general (p=0.138). Sixty-two patients (14.3%) had biopsies with suspicious radiological findings (15.8% vs. 13.1%). Eight (12.8%) of these patients had malignant results. There were local recurrences in six patients, one in the first group and five in the second group (p=0.084). Oncoplastic breast-conserving surgery may increase post-operative mammography use. However, there is no statistical difference between the two groups for either additional imaging in total or in biopsy needs.

Practical oncoplastic surgery techniques needed for practice.

Oncoplastic breast surgery (OPS) is a form of breast conservation surgery that includes immediate breast reconstruction. OPS has previously been shown to be a safe and effective treatment for breast cancer. In a special series on Breast Reconstruction, we aimed to describe oncoplastic breast reconstruction options and the corresponding technical details. Sections were divided by descriptions of OPS specific preoperative workup, volume displacement techniques, volume replacement techniques, and postoperative considerations. In addition, to sharing expert surgical pearls gained through performing OPS procedures over the years. Innovations in breast reconstruction offer women treatment options that are both oncologically safe and aesthetically preferred. The rise in reconstructive procedures is changing how patients make decisions based on their diagnosis. The ultimate surgical decision should be determined by the patient's anatomy, patient's personal preferences, tumor characteristics, and clinical presentation in a shared decision-making fashion with a multidisciplinary team. However, with both volume displacement and volume replacement techniques, women of all breast sizes can achieve an aesthetic outcome without sacrificing oncologic resection.

Oncoplastic and reconstructive breast surgery.

This article provides an overview of the principles and techniques of oncoplastic and reconstructive breast surgery for patients with early-stage breast cancer. Oncoplastic breast surgery (OPBS) with partial breast reconstruction is a natural evolution in the application of breast conserving surgery and permits wide surgical resection of tumours that might otherwise mandate mastectomy and whole breast reconstruction. These reconstructive techniques must be optimally selected and integrated with ablative breast surgery together with non-surgical treatments such as radiotherapy and chemotherapy that may be variably sequenced with each other. A multidisciplinary approach with shared decision-making is essential to ensure optimal clinical and patient-reported outcomes that address oncological, aesthetic, functional and psychosocial domains. Future practice of OPBS must incorporate routine audit and comprehensive evaluation of outcomes.

Partial breast reconstruction of 30 cases with peri-mammary artery perforator flaps

BackgroundVolume replacement is one of the vital techniques of oncoplastic surgery (OPS) when applying breast-conserving surgery. The clinical application of peri-mammary artery perforator flaps for this indication is uneven in China. Here, we describe the results of our clinical experience with peri-mammary artery flaps for partial breast reconstruction.MethodsIn this study, 30 patients underwent partial breast resection for quadrant breast cancer followed by partial breast reconstruction with peri-mammary artery perforator flaps, which included the thoracodorsal artery perforator flap (TDAP), anterior intercostal artery perforator flap (AICAP), lateral intercostal artery perforator flap (LICAP), and lateral thoracic artery perforator flap (LTAP). All the patients’ operation plans were discussed comprehensively and were performed by sticking to every step. The satisfaction outcome was assessed with the extracted version of the BREAST-Q version 2.0, Breast Conserving Therapy Module Preoperative and Postoperative Scales both preoperatively and postoperatively.ResultsAccording to the study outcomes, the mean flap size was 5.3*4.2*2.8 cm (3.0–7.0*3.0–5.0*1.0–3.5 cm). The mean surgical time was 142 min (100–250 min). No partial flap failure was detected, and no severe complications were observed. Most patients were satisfied with the outcomes regarding the dressing, sexual life, and breast shape postoperation. Furthermore, the sensation of the surgical area, scar satisfaction, and recovery state gradually improved. Overall, LICAP and AICAP had higher scores when different flaps were compared.ConclusionsBased on this study, we found that peri-mammary artery flaps had significant value in breast-conserving surgery, especially in patients with small or medium-sized breasts. Perforators could be detected by vascular ultrasound before the operation. More than one perforator could be found most of the time. No severe complications occurred when performing a suitable plan, including discussing and recording the operation procedure; the focus of care, the choice for precise and proper perforators, and the mechanism for hiding the scars were all considered and recorded in a specific chart. Patients were satisfied with the reconstruction technique of peri-mammary artery perforator flaps after breast-conserving, and the satisfaction of AICAP and LICAP was higher. In general, this technique is suitable for partial breast reconstruction and has no negative impact on patient satisfaction.

The interface between breast conserving surgery with oncoplastic techniques and mastectomy: when to perform one or the other—a narrative review

Objective: The aim of this review is to describe different oncoplastic surgery techniques and indications versus mastectomy.

The Significance of Oncoplastic Breast Reconstruction After Tumorectomy in Surgical Breast Cancer Therapy

Breast-conserving therapy (BCT), meaning tumorectomy in combination with systemic therapy and locoregional radiation therapy has become the preferred method to treat early-stage breast cancer. With excellent long-term recurrence-free and overall survival rates, breast surgeons today must deliver du- rable and aesthetically appealing results that guarantee a good quality of life to meet the high patient expectations. Oncoplas- tic breast surgery (OPBS) is an innovative approach to improve the overall results of BCT. Often carried out by a team of a plastic surgeon and an oncologic breast surgeon, OPBS can actively prevent breast deformities without compromising oncological safety. In the following, an overview of the principles and techniques of oncoplastic breast surgery will be given due to its ever-increasing significance and its advantages and dis- advantages will be discussed in the context of reconstructive breast surgery.

The iTOP trial: Comparing immediate techniques of oncoplastic surgery with conventional breast surgery in women with breast cancer - A prospective, controlled, single-center study

IntroductionOncoplastic techniques allow resection of larger tumors, permitting breast conservation in cases otherwise requiring mastectomy. We sought to prospectively compare quality of life (QoL) in patients undergoing oncoplastic surgery as compared to conventional breast conservation (CBC) or mastectomy is lacking. MethodsPatients diagnosed with BIRADS IV-VI lesion were eligible if resection of ≥10% of the breast volume was planned. Patients were allowed to decide whether they wanted to undergo CBC or oncoplastic breast conservation (OBC). Patients who underwent mastectomy and immediate breast reconstruction (IBR) were also included for comparison. The primary endpoint was breast self-esteem using the Breast Image Scale (BIS) at 12 months, secondary endpoints were perioperative morbidity and QoL using the BREAST-Q questionnaire. ResultsFrom 2011 to 2016, 205 patients were included in the study. 116 patients (56.6%) received CBC, 46 (22.4%) OBC and 43 (21%) MIBR. Women in the OBC group were more likely to have tumors ≥ 2 cm than those in the CBC group (34.7% vs. 17.5%, respectively). Women who underwent MIBR were more likely to have tumors > 5 cm than those in the CBC and OBC groups (23% vs 1% and 10%, respectively). The BIS and BREAST-Q improved in each group after 12 months but did not differ significantly between groups at any time point. Surgical complications (seroma, bleeding, infection, necrosis) were numerically more likely in the OBC and MIBR groups. ConclusionOBC and the MIBR allow for resection of larger tumors with a similar quality of life as CBC.

Comparison of patient-reported outcomes among different types of oncoplastic breast surgery procedures

This study aims to compare patient-reported outcomes (PROs) after different types of oncoplastic surgery (OPS) procedures and correlate the results with previously published normative data from women with no prior history of breast cancer (BC) and breast surgery. Cross-sectional study of patients with stage I-II BC undergoing a specific selection of OPS procedures from 04/2012 to 12/2018 by three breast surgeons at a single tertiary referral hospital in Switzerland. PROs were evaluated using the postoperative BREAST-Q questionnaire. One hundred twenty-seven patients met the inclusion criteria and were surveyed. All OPS techniques achieved comparably elevated scores in satisfaction with breasts, psychosocial, and sexual well-being. Compared to normative data of healthy women, all OPS groups postoperatively achieved significantly better satisfaction with breasts, psychosocial, and sexual well-being. This study shows high PROs across all types of OPS, which were superior to normative data from healthy women. Our findings confirm that OPS is associated with high quality of life and patient satisfaction.

Oncoplastic and Reconstructive Breast Surgery: A Comprehensive Review.

Most of the approaches that were valid until recently in breast cancer surgery have undergone significant changes with rising awareness, increasing number of patients, and knowledge. It is important to repair the damage caused by surgical treatment performed in accordance with oncological principles and to obtain good cosmetic results. The quality-of-life indexes increase and body image is positively affected by the development of oncoplastic surgery and reconstruction techniques.The oncoplastic techniques are commonly used for the closure of glandular defects. Surgeons must pay attention to the breast volume, tumor location, the amount of breast tissue that would be removed, and the oncoplastic technique that may be required. Oncoplastic breast surgery allows wide local excision of the mass with good cosmetic results. In addition, a contralateral breast lift, breast augmentation or breast reduction may be required to accommodate the conceptually reconstructed breast. The use of oncoplastic breast surgery techniques results in lower mastectomy rates with equivalent local and long-term survival rates as compared with mastectomy and offers women the option of plastic and reconstructive interventions performed at the time of initial surgery. Mastectomy may be needed for large tumors, as breast-conserving surgery may not be possible or may not produce satisfactory cosmetic results. Breast reconstruction methods after mastectomy include autologous or implant-based breast reconstructions, which can be performed at the same time as the breast cancer surgery (immediate reconstruction) or at a later time (delayed reconstruction).Oncoplastic and reconstructive breast surgery minimizes the impact of breast cancer surgery and yields equivalent survival outcomes without psychological morbidity. With advanced techniques, better breast image than before can also be achieved. In this review, the technical details of oncoplastic breast surgery, surgical margin positivity management, reconstruction methods, radiation therapy given after reconstruction surgery, radiologic imaging modalities, and management of complications are discussed.

El futuro de la cirugía oncoplástica en España

Throughout all the articles in this Supplement of the Senology and Breast Pathology journal, the different techniques of Oncoplastic Surgery (OC) that are currently being developed in the world of Breast Surgery have been described. In this article we will describe the current situation of Oncoplastic surgery in Spain and the possibilities to improve in the future through specific training proposals and projects.

Radiology in oncoplastic surgery

Communication and collaboration between radiologist and surgeon has a key role for planning oncolpastic surgery in order to choose the best option for the patient. Radiology furthermore has also a pivotal role prior to surgery itself and during follow up for early detection of recurrence.In this paper, we provide an overview of conventional and emerging breast imaging techniques in oncoplastic surgery, considering the preoperative peri-operative and post-operative pivotal role of breast radiologists.

Oncoplastic Breast Surgery: Is it reliable in the treatment of multifocal breast cancer? A preliminary report of a prospective randomized controlled trial

Background/Aim: Multifocal breast cancers (MFBCs) still have undiscoverable clinical significance. Being the standard surgical management for early breast cancer, implementation of breast-conservation therapy (BCT) as a surgical procedure for multifocal breast cancers is still questionable and needs a solid basis of clinical evidence via prospective randomized control trials. Methods: A prospective study was conducted on female patients with operable multifocal breast cancer excluding those diagnosed with inflammatory breast cancer and those to receive neoadjuvant therapy. Surgical management was selected randomly and comprised either modified radical mastectomy (MRM) or different techniques of oncoplastic breast surgery (OPS) with a sealed envelope system based on clinical evaluation and recent guidelines for management at the Surgical Oncology Unit, Alexandria University from May 2017-May 2018. The patients were followed up until February 2021 with a median follow-up of 39 months postoperatively to assess recurrence. Analysis of different clinicopathological factors was performed to evaluate the reliability of OPS in the surgical management of MFBCs. Results: A total of 132 patients were initially assessed for the eligibility criteria. Finally, 58 patients in the OPS group and 56 patients in the MRM group were followed up until the end of the study period. After a median follow-up of 39 months post-operatively for both groups, three patients belonging to the oncoplastic group suffered from local recurrence (5.2%). Two patients who had MRM had distant recurrence (3.6%). Although recurrence behavior was different between both groups, this was not statistically significant. Conclusion: OPS is an oncologically safe surgical option for selected cases of multifocal breast cancer.

Unplanned breast‐conserving surgery after systemic therapy in locally advanced breast cancer: The results of level II oncoplastic techniques

In patients with breast cancer for whom neoadjuvant chemotherapy (NAC) is planned, it is recommended to mark the primary tumour before treatment (planned surgery). However, surgeons may have to perform breast-conserving surgery on patients whose tumours are not marked (unplanned surgery). This study focused on the results obtained with planned and unplanned level II oncoplastic surgery (OPS) techniques applied to patients after NAC. Patient groups who underwent planned, unplanned OPS and mastectomy after NAC were compared. Surgical margin status, re-operation and re-excision requirements, ipsilateral breast tumour recurrence (IBTR) and axillary recurrence rates recorded. Long-term local recurrence-free survival (LRFS), disease-free survival and overall survival were evaluated. There was no significant difference between the planned and unplanned OPS groups in terms of surgical margin status, re-excision requirement, and mastectomy rates. During an average follow-up period of 43months, 5.3% and 4% of the patients in the planned OPS group developed IBTR and axillary recurrence, respectively, whereas these rates were 6.6% and 5.3% in the unplanned OPS group. In the mastectomy group, the rates of IBTR and axillary recurrence were found to be 4.1% and 3.8%, respectively. There was no significant difference between the three groups in terms of IBTR (P: .06) and axillary recurrence (P: .08) rates. Breast conserving surgery can be applied using level II OPS techniques with the post-NAC radiological examination and marking even if primary tumour marking is not done in the pre-NAC period.

Outcomes of Asian Women Treated With Grisotti Flap Reconstruction for Centrally Located Breast Cancers: 5-Years Single Institutional Experience.

Breast conserving surgeries were previously contraindicated for central breast cancers because of poor cosmetic outcomes of central mastectomy without oncoplastic surgery. Grisotti flap is a breast-conserving surgery incorporating oncoplastic surgery technique for centrally located breast cancers. We present our experience and outcome from Breast Surgery Unit, University Malaya Medical Center. A prospective analysis of 15 patients with central retroareolar breast cancer operated from 2012 to 2018 in University Malaya Medical Center. We assessed postoperative complications, margins, locoregional recurrence, and survival outcome. All patients received postoperative radiotherapy. Patients were followed-up 1 week, 1 month, 3 monthly for 1 year and 6 monthly for 5 years. Mean age of patients is 62 years. Mean follow-up is 51 months (15-84 months). All tumors were less than 5 cm (1-2.5 cm). Majority of the patients are stage 1 (6 patients/40%) and stage 2 (8 patients/ 53.3%). 2 patients had surgical site infection resolved with antibiotics. One patient had hematoma. None require reoperation. Tumor margins were clear in all patients. No locoregional recurrence. Overall survival is 100%. All are satisfied with their cosmetic outcomes. Grisotti flap is a volume displacement technique, which provides satisfactory cosmetic outcome for centrally located breast cancer. This evolutionary thinking leads us to changes in existing techniques with the purpose of achieving oncological safety while reaching for better esthetic results. Our 5 years' experience in Asian population showed that this technique is oncologically safe with good cosmetic outcomes and could be used selectively. It provides a good alternative in patients who are otherwise subjected for mastectomy. This relatively simple technique is a worthwhile endeavor and should be offered when feasible.

Oncoplastic Level II Surgical Techniques for Breast Cancer Treatment: Long-Term Outcomes

Background: Problems in patients who could not get adequate surgical margins (SM) and good cosmetic results with breast-conserving surgery (BCS) have been overcome with the introduction of oncoplastic surgery (OPS) methods. The purpose of this study was the documentation of level II techniques and the presentation of long-term survival results. Methods: The data on patients who had been prospectively registered in the database between 2007 and 2017 and who had been treated with level II OPS due to invasive breast cancer were examined. Results: A total of 1,074 patients were included in the study. The most commonly applied level II oncoplastic techniques were performed in the upper outer quadrantectomy with racquet incision in 334 (31%) patients, inferior pedicle flaps in 294 (27.3%), and vertical mammoplasty in 140 (13%). Reexcision was performed in 96 patients (8.9%). Total breast conservation rate was 96%. Five-year disease-free survival (DFS) was 88%, local recurrence-free survival (LRFS) 93.6%, and overall survival (OS) 96%. Ten-year DFS was 72%, LRFS 85.4%, and OS 90.2%. Conclusion: Level II OPS techniques have low reoperation and complication rates and a high rate of breast protection. The success of these techniques has been demonstrated in terms of long-term local control. Awareness of the fact that many patients who undergo OPS will not lose their breasts should be created, and regular training programs for OPS techniques should be conducted especially in developing countries. By revealing these results, it is hoped that the OPS and breast conservation rates will increase.

Feasibility of level II oncoplastic techniques in the surgical management of locally advanced breast cancer after neoadjuvant treatment.

The study aimed to identify the short- and long-term oncological results and complications of level-II oncoplastic surgery (OPS) techniques applied after neoadjuvant chemotherapy (NAC) for locally advanced breast cancer. Patients undergoing OPS because of breast cancer (non-NAC) and those undergoing OPS after systemic treatment (NAC) were evaluated. Surgical margin (SM) status, reoperation and re-excision requirements, axillary intervention results, ipsilateral tumour recurrence, axillary recurrence rates and early postoperative complications were recorded. Long-term locoregional recurrence-free survival (LRFS) and overall survival (OS) rates of the patients were analysed. There were 1043 patients (893 patients in the non-NAC group and 150 in the NAC group) in the study. There were no significant differences in SM status, re-excision and mastectomy rates between the groups. The 5-year (LRFS) rate was 90.1% in the NAC group and 93.2% in the non-NAC group (P: .09). OS was shorter in the NAC group. Five-year OS rate was 96% in the non-NAC group and 92% in the NAC group (P: .01). There was no significant difference between the groups in terms of delayed wound healing, minor wound infection, fat necrosis, seroma/hematoma, partial nipple necrosisor T-junction necrosis. It should be noted that the responses to NAC increased with targeted therapies, and breast-conserving became possible in a substantial number of patients who were not eligible for breast-conserving surgery at the first presentation. Notably, oncoplastic surgery increased breast conservation rates without compromising oncological results.
