Abstract
Considering the rising prevalence of breast reconstruction followed by radiotherapy (RT), evaluating the cosmetic impact of RT is crucial. Currently, there are limited tools for objectively assessing cosmetic outcomes in patients who have undergone reconstruction. Therefore, we validated the cosmetic outcome using a previously developed anomaly Generative Adversarial Network (GAN)-based model and evaluated its utility. Between January 2016 and December 2020, we collected computed tomography (CT) images from 82 breast cancer patients who underwent immediate reconstruction surgery followed by radiotherapy. Among these patients, 38 received immediate implant insertion, while 44 underwent autologous breast reconstruction. Anomaly scores (AS) were estimated using an anomaly GAN model at pre-RT, 1st follow-up, 1-year (Post-1Y) and 2-year (Post-2Y) after RT. Subsequently, the scores were analyzed in a time-series manner, considering reconstruction types (implant versus autologous), RT techniques, and the incidence of major complications. The median age of the patients was 46 years (range 29-62). The AS between Post-1Y and Post-2Y demonstrated a positive relationship (coefficient 0.515, P < 0.001). The AS was significantly associated with objective cosmetic indices, namely Breast Contour Difference (P = 0.009) and Breast Area Difference (P = 0.004), at both Post-1Y and Post-2Y. Subgroup analysis stratified by type of breast reconstruction revealed significantly higher AS values in patients who underwent prosthetic implant insertion compared to those with autologous reconstruction at all follow-up time points (1st follow-up, P = 0.001; Post-1Y, P < 0.001; and Post-2Y, P < 0.001). A threshold AS of ≥ 1.9 was associated with a 10% predicted risk of developing major complications. The feasibility of an AS generated by a GAN model for predicting both cosmetic outcomes and the likelihood of complications following RT has been successfully validated. Further investigation involving a larger patient cohort is warranted.

PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2024; 12:e5599. [PMID: 38322813 PMCID: PMC10846766 DOI: 10.1097/gox.0000000000005599] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Accepted: 12/15/2023] [Indexed: 02/08/2024]
Abstract
Background Post mastectomy radiotherapy (PMRT) is an independent predictor of reconstructive complications. PMRT may alter the timing and type of reconstruction recommended. This study aimed to create a machine learning model to predict the probability of requiring PMRT after immediate breast reconstruction (IBR). Methods In this retrospective study, breast cancer patients who underwent IBR from January 2017 to December 2020 were reviewed and data were collected on 81 preoperative characteristics. Primary outcome was recommendation for PMRT. Four algorithms were compared to maximize performance and clinical utility: logistic regression, elastic net (EN), logistic lasso, and random forest (RF). The cohort was split into a development dataset (75% of cohort for training-validation) and 25% used for the test set. Model performance was evaluated using area under the receiver operating characteristic curve (AUC), precision-recall curves, and calibration plots. Results In a total of 800 patients, 325 (40.6%) patients were recommended to undergo PMRT. With the training-validation dataset (n = 600), model performance was logistic regression 0.73 AUC [95% confidence interval (CI) 0.65-0.80]; RF 0.77 AUC (95% CI, 0.74-0.81); EN 0.77 AUC (95% CI, 0.73-0.81); logistic lasso 0.76 AUC (95% CI, 0.72-0.80). Without significantly sacrificing performance, 81 predictive factors were reduced to 12 for prediction with the EN method. With the test dataset (n = 200), performance of the EN prediction model was confirmed [0.794 AUC (95% CI, 0.730-0.858)]. Conclusion A parsimonious accurate machine learning model for predicting PMRT after IBR was developed, tested, and translated into a clinically applicable online calculator for providers and patients.

Breast Reconstruction following Mastectomy for Breast Cancer or Prophylactic Mastectomy: Therapeutic Options and Results. Life (Basel) 2024; 14:138.

Abstract
(1) Importance of problem: Breast cancer accounted for 685,000 deaths globally in 2020, and half of all cases occur in women with no specific risk factor besides gender and age group. During the last four decades, we have seen a 40% reduction in age-standardized breast cancer mortality and have also witnessed a reduction in the medium age at diagnosis, which in turn means that the number of mastectomies performed for younger women increased, raising the need for adequate breast reconstructive surgery. Advances in oncological treatment have made it possible to limit the extent of what represents radical surgery for breast cancer, yet in the past decade, we have seen a marked trend toward mastectomies in breast-conserving surgery-eligible patients. Prophylactic mastectomies have also registered an upward trend. This trend together with new uses for breast reconstruction like chest feminization in transgender patients has increased the need for breast reconstruction surgery. (2) Purpose: The purpose of this study is to analyze the types of reconstructive procedures, their indications, their limitations, their functional results, and their safety profiles when used during the integrated treatment plan of the oncologic patient. (3) Methods: We conducted an extensive literature review of the main reconstructive techniques, especially the autologous procedures; summarized the findings; and presented a few cases from our own experience for exemplification of the usage of breast reconstruction in oncologic patients. (4) Conclusions: Breast reconstruction has become a necessary step in the treatment of most breast cancers, and many reconstructive techniques are now routinely practiced. Microsurgical techniques are considered the "gold standard", but they are not accessible to all services, from a technical or financial point of view, so pediculated flaps remain the safe and reliable option, along with alloplastic procedures, to improve the quality of life of these patients.

Impact of Prepectoral vs. Subpectoral Tissue Expander Placement on Post-mastectomy Radiation Therapy Delivery: A Retrospective Cohort Study. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2023; 11:e5434. [PMID: 38115839 PMCID: PMC10730031 DOI: 10.1097/gox.0000000000005434] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Accepted: 10/05/2023] [Indexed: 12/21/2023]
Abstract
Background Implant-based reconstruction is the most common method of postmastectomy reconstruction. Many patients require postmastectomy radiation (PMRT). Tissue expanders (TEs), typically inserted as a first stage, have historically been placed subpectorally. More recently, prepectoral reconstruction has gained popularity, but its impact on PMRT is unknown. Prior studies focus on complication rates and aesthetic outcomes. This study examines whether there is a difference in radiation dosimetry among patients undergoing prepectoral versus subpectoral TE reconstruction. Methods Electronic medical records and radiation plans of 50 patients (25 prepectoral, 25 subpectoral) who underwent mastectomy with immediate TE reconstruction at our institution or affiliate site were reviewed. Pectoralis major muscle and chest wall structures were contoured and mean percentage volumes of these structures receiving less than 95%, 100%, and more than 105% target radiation dose were calculated, as were heart and ipsilateral lung doses. Welch two sample t test, Fisher exact test, and Pearson chi-squared tests were performed. Results The groups had comparable patient and tumor characteristics and underwent similar ablative and reconstructive procedures and radiation dosimetry. Subpectoral patients had larger mean areas receiving less than 95% target dose ("cold spots"); prepectoral patients had larger mean areas receiving greater than 105% ("hot spots") and 100% target doses. There were no differences in chest wall, heart, and lung doses. Conclusions Our results demonstrate an increased mean percentage area of pectoralis cold spots with subpectoral reconstruction and increased area of hot spots and 100% dose delivery to the pectoralis in prepectoral patients. Larger studies should analyze long-term effects of prepectoral reconstruction on radiation dosing and recurrence rates.

Abstract
Adipose tissue is composed of a collection of cells with valuable structural and regenerative function. Taken as an autologous graft, these cells can be used to address soft tissue defects and irregularities, while also providing a reparative effect on the surrounding tissues. Adipose-derived stem or stromal cells are primarily responsible for this regenerative effect through direct differentiation into native cells and via secretion of numerous growth factors and cytokines that stimulate angiogenesis and disrupt pro-inflammatory pathways. Separating adipose tissue into its component parts, i.e., cells, scaffolds and proteins, has provided new regenerative therapies for skin and soft tissue pathology, including that resulting from radiation. Recent studies in both animal models and clinical trials have demonstrated the ability of autologous fat grafting to reverse radiation induced skin fibrosis. An improved understanding of the complex pathologic mechanism of RIF has allowed researchers to harness the specific function of the ASCs to engineer enriched fat graft constructs to improve the therapeutic effect of AFG.

Abstract
AIMS AND OBJECTIVES To systematically evaluate the effects of decision aids for women facing breast reconstruction decision on decision conflict, decision regret, knowledge, satisfaction, anxiety and depression. BACKGROUND Breast reconstruction decision is not good or bad and should be guided by clinical evidence and patient preferences. Decision aids can increase the patient's decision-making enthusiasm and ability, improve the quality of decision and promote shared decision-making between patients and medical staff. DESIGN Systematic review and meta-analysis. METHODS Eight databases were conducted from the establishment of the database until October 2021. The PRISMA checklist was selected for analysis in this paper. The meta-analysis was conducted in Review Manager 5.3. The quality of the studies was assessed using the Cochrane risk-of-bias tool. The result is decision conflict, decision regret, knowledge and other secondary outcomes. Sensitivity analysis and subgroup analysis were also conducted. RESULTS A total of twelve randomised controlled trials (RCTs) were included in the systematic review and meta-analysis. Meta-analysis revealed that decision aids could significantly reduce decision conflict and decision regret, improve knowledge, satisfaction and depression and had no influence on anxiety. CONCLUSIONS The results of the systematic review and meta-analysis reviewed the positive effect of decision aids on the decision-making of women facing postmastectomy breast reconstruction. In the future, more well-designed RCTs are needed to confirm the effects of decision aids on the decision-making of breast reconstruction and nurses should be encouraged to take part in the development of decision aids in accordance with strict standards and apply them to breast cancer patients considering postmastectomy breast reconstruction. RELEVANCE TO CLINICAL PRACTICE Our study provides evidence for the effectiveness of decision aids on breast reconstruction and points to the important role of healthcare providers in the use of decision aids and in facilitating shared decision-making.

Abstract
BACKGROUND Postmastectomy breast reconstruction in patients with a history of breast-conserving surgery (BCS) and radiotherapy is challenging, with a paucity of literature on the outcomes of different breast reconstructive techniques. The authors hypothesized that implant-based breast reconstruction (IBR) would be associated with higher complication rates compared to either IBR combined with latissimus dorsi (LD) or free flap breast reconstruction (FFBR). METHODS The authors conducted a retrospective review of patients who underwent mastectomy with a history of BCS and radiotherapy between January of 2000 and March of 2016. Surgical and patient-reported outcomes (BREAST-Q) were compared between IBR versus IBR/LD versus FFBR. RESULTS The authors identified 9473 patients who underwent BCS and radiotherapy. Ninety-nine patients (105 reconstructions) met the authors' inclusion criteria, 29% ( n = 30) of whom underwent IBR, 26% ( n = 27) of whom underwent IBR/LD, and 46% ( n = 48) of whom underwent FFBR. The overall complication rate was not significantly different between the three groups (50% in IBR versus 41% in IBR/LD versus 44% in FFBR; P = 0.77), whereas reconstruction failures were significantly lower in the FFBR group (33% in IBR versus 19% in IBR/LD versus 0% in FFBR; P < 0.0001). The time between the receipt of radiotherapy and reconstruction was not a significant predictor of overall complications and reconstruction failure. No significant differences were identified between the three study cohorts in any of the three studied BREAST-Q domains. CONCLUSIONS In patients with prior BCS and radiotherapy, FFBR was associated with lower probability of reconstruction failure compared to IBR but no significant difference in overall and major complication rates. The addition of LD flap to IBR did not translate into lower complication rates but may result in decreased reconstruction failures. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Abstract
The aim of this study is to evaluate cosmetic outcomes of the reconstructed breast in breast cancer patients, using anomaly score (AS) detected by generative adversarial network (GAN) deep learning algorithm. A total of 251 normal breast images from patients who underwent breast-conserving surgery were used for training anomaly GAN network. GAN-based anomaly detection was used to calculate abnormalities as an AS, followed by standardization by using z-score. Then, we reviewed 61 breast cancer patients who underwent mastectomy followed by reconstruction with autologous tissue or tissue expander. All patients were treated with adjuvant radiation therapy (RT) after reconstruction and computed tomography (CT) was performed at three-time points with a regular follow-up; before RT (Pre-RT), one year after RT (Post-1Y), and two years after RT (Post-2Y). Compared to Pre-RT, Post-1Y and Post-2Y demonstrated higher AS, indicating more abnormal cosmetic outcomes (Pre-RT vs. Post-1Y, P = 0.015 and Pre-RT vs. Post-2Y, P = 0.011). Pre-RT AS was higher in patients having major breast complications (P = 0.016). Patients with autologous reconstruction showed lower AS than those with tissue expander both at Pre-RT (2.00 vs. 4.19, P = 0.008) and Post-2Y (2.89 vs. 5.00, P = 0.010). Linear mixed effect model revealed that days after baseline were associated with increased AS (P = 0.007). Also, tissue expander was associated with steeper rise of AS, compared to autologous tissue (P = 0.015). Fractionation regimen was not associated with the change of AS (P = 0.389). AS detected by deep learning might be feasible in predicting cosmetic outcomes of RT-treated patients with breast reconstruction. AS should be validated in prospective studies.

Abstract
A 55-year-old woman with previous skin-sparing mastectomy and prosthetic reconstruction for multifocal ductal carcinoma developed homolateral axillary recurrence. Following nodal dissection, partial periprosthetic capsulectomy and the overlying breast skin excision, the pathology report revealed a positive cutaneous margin. Since further breast skin excision or radiotherapy would have compromised the prosthetic implant, and the patient was adamant about avoiding any endangering intervention, the multidisciplinary recommendation included skin-directed electrochemotherapy (ECT) in the frame of a multimodal treatment strategy. The procedure lasted 20 minutes under mild general sedation and included a bolus of intravenous bleomycin followed by local application of electric pulses using a needle electrode. The postprocedural course was uneventful, except for mild dermatologic toxicity. At 5 years, the patient is disease-free with the implant in situ. This report illustrates the proof-of-concept of adjuvant skin-sparing ECT to sterilize resection margins, preserve a breast implant and highlight procedural details to avert toxicity.

Adjuvant radiotherapy could be a necessary step in the oncological treatment for breast cancer. However, radiotherapy may have negative effects on implant-based immediate breast reconstruction. The aim of this study was to determine the impact of adjuvant radiation therapy on surgical results and patient-reported satisfaction outcomes in women undergoing immediate implant-based breast reconstruction. Methods A systematic search in PubMed was conducted on September 2019 and updated on April 2021. The risk of bias of the included studies was assessed using the Newcastle-Ottawa Quality Assessment Form for Observational Studies. RevMan 5 was used for statistical analysis. We obtained relative risks to determine the complication incidence and mean differences for 2-year BREAST-Q scores. Results Fourteen studies were included. A total of 11,958 implant-based immediate reconstructions were performed, 2311 received postmastectomy radiation therapy, and 9647 were considered as control group. Surgical complications, reoperation rates, and reconstruction failure were significantly higher among irradiated breasts. Significantly lower BREAST-Q scores were reported by irradiated women receiving radiotherapy. Conclusions This systematic review and meta-analysis combines reconstruction complication rates with aesthetic and patient-reported satisfaction outcomes. Adjuvant radiotherapy is consistently associated with greater complication rates and poorer aesthetic and satisfaction outcomes. The magnitude of association is significantly lower when the reconstruction is based on autologous tissues.

Considering the type and timing of breast reconstruction after mastectomy: Qualitative insights into women's decision-making. Eur J Oncol Nurs 2021; 54:102024. [PMID: 34536790 DOI: 10.1016/j.ejon.2021.102024] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2021] [Revised: 05/05/2021] [Accepted: 08/26/2021] [Indexed: 10/20/2022]
Abstract
PURPOSE The information women receive about the type and timing of breast reconstruction (BR) from healthcare providers is crucial to help them make an informed decision, and this is particularly important in complex cases and/or high-risk cases. This study sought to provide qualitative insights into Australian women's BR decision-making experiences. METHOD Twenty-nine women who had received a mastectomy and made decisions about BR, including the type (expander, implant and/or autologous) and timing (immediate, delayed or immediate-delayed), participated in semi-structured telephone interviews. Interviews were analysed thematically using the Framework method. RESULTS Seven themes were identified: 1) information provision and needs; 2) values and preferences; 3) pressure to decide; 4) feasibility (e.g. clinical and/or financial factors); 5) social influence and support; 6) multidisciplinary team and organisational structures; and 7) decision implementation and outcomes. Breast care nurse support, as well as collaboration and communication within multidisciplinary teams were perceived by women as facilitating the BR decision-making process. CONCLUSIONS The identified themes offer an in-depth explanation of how a sample of Australian women make BR decisions. The current findings highlight the often limited clinician-patient information-sharing and demonstrate the overarching influence of the multidisciplinary medical team and organisational structures on BR decision-making. Development of in-consult decision-aids and strategies to improve multidisciplinary care are discussed.

Abstract
Radiation therapy is a valuable tool in the treatment of numerous malignancies but, in certain cases, can also causes significant acute and chronic damage to noncancerous neighboring tissues. This review focuses on the pathophysiology of radiation-induced damage and the clinical implications it has for plastic surgeons across breast reconstruction, osteoradionecrosis, radiation-induced skin cancers, and wound healing. The current understanding of treatment modalities presented here include hyperbaric oxygen therapy, autologous fat grafting and stem cells, and pharmaceutical agents.

Abstract
Radiation therapy is frequently a critical component of breast cancer care but carries with it side effects that are particularly damaging to reconstructive efforts. Autologous lipotransfer has the ability to improve radiated skin throughout the body due to the pluripotent stem cells and multiple growth factors transferred therein. The oncologic safety of lipotransfer to the breasts is demonstrated in the literature and is frequently considered an adjunctive procedure for improving the aesthetic outcomes of breast reconstruction. Using lipotransfer as an integral rather than adjunctive step in the reconstructive process for breast cancer patients requiring radiation results in improved complication rates equivalent to those of nonradiated breasts, expanding options in these otherwise complicated cases. Herein, we provide a detailed review of the cellular toxicity conferred by radiotherapy and describe at length our approach to autologous lipotransfer in radiated breasts.

Abstract
In the past, acellular dermal matrices (ADMs) have been used in implant-based breast reconstruction. Various factors affect the clinical performance of ADMs since there is a lack of systematic characterization of ADM tissues. This study used BellaCell HD and compared it to two commercially available ADMs—AlloDerm Ready to Use (RTU) and DermACELL—under in vitro settings. Every ADM was characterized to examine compatibility through cell cytotoxicity, proliferation, and physical features like tensile strength, stiffness, and the suture tensile strength. The BellaCell HD displayed complete decellularization in comparison with the other two ADMs. Several fibroblasts grew in the BellaCell HD with no cytotoxicity. The proliferation level of fibroblasts in the BellaCell HD was higher, compared to the AlloDerm RTU and DermACELL, after 7 and 14 days. The BellaCell HD had a load value of 444.94 N, 22.44 tensile strength, and 118.41% elongation ratio, and they were higher than in the other two ADMs. There was no significant discrepancy in the findings of stiffness evaluation and suture retention strength test. The study had some limitations because there were many other more factors useful in ADM’s testing. In the study, BellaCell HD showed complete decellularization, high biocompatibility, low cytotoxicity, high tensile strength, high elongation, and high suture retention strengths. These characteristics make BellaCell HD a suitable tissue for adequate and safe use in implant-based breast reconstruction in humans.

Immediate Latissimus Dorsi and Prosthetic Reconstruction in the Setting of Postmastectomy Radiation: An Analysis of 376 Breast Reconstructions. Ann Plast Surg 2020; 84:S364-S368.

Abstract
BACKGROUND In immediate breast reconstruction, the plastic surgeon must strive to create an aesthetically pleasing result while minimizing complications. The latissimus dorsi (LD) myocutaneous flap has long been used a workhorse flap in breast reconstruction. Often times, it is used a salvage flap after other methods of breast reconstruction have failed. In this study, we review the use of this flap in conjunction with prosthetic devices, regardless of the need for adjuvant radiation, to determine the safety and efficacy of this approach as a primary method of reconstruction. METHODS A single surgeon practice with a standardized reconstructive algorithm was reviewed. This compromises a 2-stage approach involving the use of LD myocutaneous flaps and tissue expanders for immediate reconstruction after mastectomy, followed by exchange for implants at a secondary surgery. A retrospective chart review was performed on 201 patients (376 breast reconstructions) who met inclusion criteria. Patient demographics and outcomes were compared based on radiation status. The primary outcome, reconstructive success, was defined as no need for further autologous reconstruction beyond the 2-stage approach utilized. RESULTS Statistical analysis was performed on both patient demographics, complications, and reconstructive outcomes. Demographics were equivalent between the 2 groups. When analyzing complications and outcomes, there was no difference between nonradiated patients and radiated patients except when looking at reconstructive loss, which was 3.6% in the nonradiated group and 16.6% in the radiated group (P = 0.03). However, one third of the patients in the radiated group who had reconstructive losses were due to reasons not related to radiation therapy. Taking this into account, overall reconstructive success showed no statistical significance between the 2 groups. CONCLUSIONS The findings from this study show that immediate reconstruction with LD myocutaneous flaps in conjunction with prosthetic devices is a reliable and safe option, even in the setting of adjuvant radiation therapy, as the autologous tissue mitigates many sequelae of radiation therapy. Not only does this type of reconstruction provide an aesthetically pleasing result in 2 stages, but also has a favorable complication profile and success rate.

Abstract
BACKGROUND Conflicting evidence challenges clinical decision-making when breast reconstruction is considered in the context of radiotherapy. Current literature was evaluated and key statements on topical issues were generated and discussed by an expert panel at the International Oncoplastic Breast Surgery Meeting in Milan 2017. METHODS Studies on radiotherapy and breast reconstruction (1985 to September 2017) were screened using MEDLINE, Embase and CENTRAL. The literature review yielded 30 controversial key questions. A set of key statements was derived and the highest levels of clinical evidence (LoE) for each of these were summarized. Nineteen panellists convened for dedicated discussions at the International Oncoplastic Breast Surgery Meeting to express agreement, disagreement or abstention for the generated key statements. RESULTS The literature review identified 1522 peer-reviewed publications. A list of 22 key statements was produced, with the highest LoE recorded for each statement. These ranged from II to IV, with most statements (11 of 22, 50 per cent) supported by LoE III. There was full consensus for nine (41 per cent) of the 22 key statements, and more than 75 per cent agreement was reached for half (11 of 22). CONCLUSION Poor evidence exists on which to base patient-informed consent. Low-quality studies are conflicting with wide-ranging treatment options, precluding expert consensus regarding optimal type and timing of breast reconstruction in the context of radiotherapy. There is a need for high-quality evidence from prospective registries and randomized trials in this field.

Abstract
BACKGROUND This study was performed to determine if there was a difference in immediate breast reconstruction (IBR) rates between our public hospital and private cancer center, which share a common faculty with a consistent management philosophy in multidisciplinary care. We investigated the factors affecting postmastectomy reconstruction and IBR rates. MATERIALS AND METHODS We retrospectively identified women with clinical stage I-II breast cancer who underwent mastectomy at our public hospital, Los Angeles County Medical Center, and our private cancer center, Keck Hospital of USC/Norris Comprehensive Cancer Center. Univariate and multivariate analyses were performed to study predictors of IBR and any breast reconstruction. RESULTS Of 293 mastectomy patients, the rate of any breast reconstruction at the private cancer (56.6%) center was higher than that at the public hospital (36.2%). IBR rates for the private cancer center (93.6%) and for patients with private insurance were higher than for the public hospital (40.8%) and likewise for those without insurance (86.7% versus 45.5%). In a multivariate analysis, the odds of IBR at our private cancer center were 22.96 times higher than that at our public hospital. Age >50 y and radiotherapy were independent predictive factors associated with less likelihood of any breast reconstruction. CONCLUSIONS Patients at the public hospital had a much lower rate of breast reconstruction than the private cancer center patients, even after controlling for stage and the team of treating physicians. Our results showed that older age and radiotherapy affect rates of breast reconstruction, as do hospital system and insurance status.

Abstract
INTRODUCTION Axillary ultrasound staging (AUS) is an important tool to guide clinical decisions in breast cancer therapy, especially regarding axillary surgery but also radiation therapy. It is unknown whether biological subtypes influence axillary staging using ultrasound (AUS). METHOD This is a retrospective single center analysis. All patients with breast cancer, a preoperative axillary ultrasound and a complete surgical axillary staging were included between 1999 and 2014, except patients with neoadjuvant chemotherapy (NACT). The results of the AUS were compared with final pathological results. Biological subtypes were identified by immunohistochemistry. RESULTS 583 women were included in the study. Sensitivity, Specificity, positive and negative predictive value for AUS were 39%, 96%, 91% and 83%. While sensitivity was significantly lower in Luminal A and B patients (25.0%; 39.8%) as compared to non Luminal breast cancer patients (TN 68.8%; Her2+ 71.4%; p = 0.0032), there were no significant differences between the groups with respect to specificity, PPV and NPV. CONCLUSION Solely regarding sensitivity of AUS, our study could show significant differences between biological subtypes of breast cancer with lower sensitivity in Luminal patients. While PPV was excellent, standing for a low overtreatment rate using AUS for clinical decision making, sensitivity was poor overall, comparable to the results of other studies.
