The use of a breast symmetry index for objective evaluation of breast cosmesis

Publication Trends in Aesthetic Breast Surgery: A Bibliometric Analysis

Background

Aesthetic breast surgery (ABS) encompasses breast augmentation, breast reduction, mastopexy, and mastopexy augmentation. This topic has seldom been assessed as a bibliometric study. This analysis aims to address this gap and identify trends in ABS literature to guide future research areas. Bibliometrics, the quantitative analysis of publications, particularly scholarly literature, offers valuable insights into research trends and impact.

Objectives

This analysis aims to address this gap and identify trends in ABS literature to guide future research areas.

Methods

The 100 most-cited publications in ABS were identified on Web of Science (Clarivate Analytics, Philadelphia, PA), across all available journal years (from 1953 to 2024). Study details, including the citation count, main content focus, and outcome measures, were extracted and tabulated from each publication. The Oxford Centre for Evidence Based Medicine and levels of evidence (LOE) of each study were assessed.

Results

The 100 most-cited publications in ABS were cited by a total of 11,522 publications. Citations per publication ranged from 46 to 1211 (mean 115.2 ± 135.7), with the highest-cited study being the Pusic BREAST-Q paper (n = 1211). A majority of publications were LOE 4 (n = 30), representative of the large number of case series. The number of publications for LOE 5, 3, 2, and 1 was 12, 28, 21, and 9, respectively. The main content focus was "outcomes" in 52 publications, followed by "nonoperative management" (n = 12) and "surgical technique" (n = 12). Patient-reported outcome measures (PROMs) were used in 29 publications, and 53 publications reported aesthetic outcome measures.

Conclusions

This analysis highlights that research methodologies in ABS studies should be improved. This necessary improvement would be facilitated by vigorous, high-quality research, and the implementation of validated ABS-specific PROMs enhancing patient satisfaction, particularly in aesthetic procedures, such as BREAST-Q.

A Novel Artificial Intelligence Model for Symmetry Evaluation in Breast Cancer Patients

INTRODUCTION

Artificial intelligence (AI) is a milestone for human technology. In medicine, AI is set to play an important role as we progress into a new era. In plastic surgery, AI can participate in breast symmetry assessment, which until now has been mainly subjective, allowing for inconsistencies. This study aims to improve this evaluation process by integrating a novel trained neural network with the breast symmetry calculator, BAS-Calc.

MATERIALS AND METHODS

We combined the BAS-Calc tool with a custom-made neural network trained to automatically detect key features of the breast. This integrated system was tested on 81 images of patients who had undergone breast reconstruction post-breast cancer treatment. Its performance was evaluated against two human observers using statistical analysis.

RESULTS

Our model successfully detected 399/405 (98.51%) of landmarks. Spearman and Pearson correlation indicated a strong positive relationship while Cohen's kappa demonstrated moderate to strong agreement between human observers and AI model. Notably, the average calculation time for the AI was 0.92 seconds, 16 times faster than the 14.09 seconds for humans.

CONCLUSIONS

Our AI model successfully calculated breast symmetry from images of patients who had undergone reconstructive oncological breast surgery, demonstrating high correlation with human assessments and a markedly reduced processing time. As AI continues to evolve, it is poised to become a pivotal tool in Medicine. Therefore, it is crucial for medical professionals to proactively engage in implementing AI technologies safely and effectively. Further studies are required to broaden our understanding and maximize the potential benefits in this area. Takeaway bullet points Artificial intelligence (AI) is an upcoming force to be reckoned with. AI should find its way into practical applications in plastic surgery. AI can be applied to improve patient care and evaluate aesthetic results. In this work, we present a novel AI model that automatically evaluates breast symmetry.

Reverse-sequence endoscopic nipple-sparing mastectomy with immediate implant-based breast reconstruction: an improvement of conventional minimal access breast surgery

Background

Our center proposes a new technique that effectively provides space to broaden the surgical field of view and overcomes the limitations of endoscopy-assisted nipple-sparing mastectomy (E-NSM) by changing the dissection sequence and combining it with air inflation. The purpose of this study was to compare the clinical outcomes of the new technique designated "reverse-sequence endoscopic nipple-sparing mastectomy (R-E-NSM) with subpectoral breast reconstruction (SBR)" and the conventional E-NSM (C-E-NSM) with SBR.

Method

All patients undergoing E-NSM with SBR at our breast center between April 2017 and December 2022 were included in this study. The cohort was divided into the C-E-NSM group and the R-E-NSM group. The operation time, anesthesia time, medical cost, complications, cosmetic outcomes, and oncological safety were compared.

Results

Twenty-six and seventy-nine consecutive patients were included in the C-E-NSM and R-E-NSM groups, with average ages of 36.9 ± 7.0 years and 39.7 ± 8.4 years (P=0.128). Patients in the R-E-NSM group had significantly shorter operation time (204.6 ± 59.2 vs. 318.9 ± 75.5 minutes, p<0.001) and anesthesia time (279.4 ± 83.9 vs. 408.9 ± 87.4 minutes, p<0.001) and decreased medical costs [5063.4 (4439.6-6532.3) vs. 6404.2 (5152.5-7981.5), USD, p=0.001] and increase SCAR-Q scores (77.2 ± 17.1 vs. 68.8 ± 8.7, P=0.002) compared to the C-E-NSM group. Although trends increased in both the excellent rate of Ueda scores (53.8% vs. 42.3%, P = 0.144), excellent rate of Harris scores (44.0% vs. 63.1%, P=0.102), and decreased surgical complications (7.6% vs. 19.2%, P = 0.135) were observed in the R-E-NSM group, the differences were not significant. There were no significant differences in oncological outcomes between the two groups.

Conclusion

R-E-NSM improves cosmetic outcomes and efficiency of C-E-NSM, reduces medical costs, and has a trend of lower surgical complications while maintaining the safety of oncology. It is a safe and feasible option for oncological procedures that deserves to be promoted and widely adopted in practice.

Effectiveness of SCAR-Q for assessment of incisional SCAR after implant-based reconstruction in breast cancer patients: Can it be a tool for incision selection?

Incisional scarring is a factor of cosmetic appearance evaluated after breast reconstruction, along with the shape, position, and size of the breast. This study aimed to examine the effect of the incision scar location on patient satisfaction after breast reconstruction. Using the Japanese version of the SCAR-Q, we assessed the scar appearance, symptoms and psychosocial effects. Plastic surgeons performed assessments using the Manchester Scar Scale. The patients were divided into two groups: those with scars on the margins of the breast (MB group) and those with scars in the breast area (IB group). The results revealed that patients in the MB group reported significantly higher satisfaction with the scar appearance and psychological impact than those in the IB group. However, assessments using the Manchester Scar Scale did not reveal any significant differences between the two groups. In conclusion, this study underscores the importance of patient-reported outcomes in the evaluation of scar satisfaction after breast reconstruction. Patients tend to prefer and have higher satisfaction with scars along the breast margin, which offers valuable insights into surgical decisions. Further studies with larger and more diverse sample sizes are required for validation.

Quantitative assessment of breast volume changes after whole-breast irradiation for breast cancer using breast auto-segmentation

PURPOSE

This study aimed to quantitatively estimate the changes in breast volume associated with radiotherapy in patients undergoing breast-conserving surgery and whole-breast irradiation (WBI).

METHODS

Pre-WBI simulation computed tomography (CT) scans and post-WBI follow-up chest CT scans from a total of 1,151 breast cancer patients were analyzed using a deep-learning-driven auto-segmentation approach. The CT-based asymmetry index (CTAI) was calculated by dividing the volume of the irradiated breast by the volume of the contralateral breast. Significant breast shrinkage was defined as a CTAI < 0.85. To quantify changes in CTAI over the follow-up period, the CTAI ratio was determined as the post-WBI CTAI divided by the pre-WBI CTAI. A multivariate logistic regression analysis was conducted to identify potential variables associated with post-WBI significant breast shrinkage.

RESULTS

The median CTAI values for pre- and post-WBI CT scans were 0.973 (interquartile range: 0.887-1.069) and 0.866 (interquartile range: 0.773-0.967), respectively. The difference between them was statistically significant (p < 0.001). Following WBI, there was an increase in the rate of significant breast shrinkage from 16.3 to 44.8%. The CTAI ratio showed a negative association with the time interval (p < 0.001, Pearson r = - 0.310). In the multivariate logistic regression analysis, lower pre-WBI CTAI, younger age, and longer interval between CT scans were found to be significantly associated with a higher occurrence of post-WBI significant breast shrinkage.

CONCLUSION

Breast volume decreases following WBI, and this decrease is correlated with an increased duration after WBI. These findings highlight the long-term consequences of WBI on breast asymmetry.

Single axillary incision reverse-order endoscopic nipple/skin-sparing mastectomy followed by subpectoral implant-based breast reconstruction: Technique, clinical outcomes, and aesthetic results from 88 preliminary procedures

BACKGROUND

Single axillary incision reverse-order endoscopic nipple-sparing mastectomy overcomes the limitations of conventional endoscopic nipple-sparing mastectomy application. We introduce this technique and report the preliminary results of this study.

METHODS

Patients who received single axillary incision reverse-order endoscopic nipple-/skin-sparing mastectomy from May 2020 to May 2022 were enrolled from a single institution. Data were analyzed to evaluate the safety and effectiveness of this technique. Patient-reported and surgeon-reported cosmetic outcomes were collected.

RESULTS

In total, 68 patients who underwent 88 single axillary incision reverse-order endoscopic nipple-/skin-sparing mastectomy combined with subpectoral implant-based breast reconstruction were enrolled in the current study. The overall complication rate was 10.3%. In total, 2.9% of patients suffered from major complications, and 5 (7.4%) experienced minor complications. Only 1 patient experienced partial nipple-areola complex necrosis. During a median follow-up time of 24 months, the locoregional recurrence and distant metastasis rate was both 1.6%. In the surgeon-reported cosmetic results, 92.1% of patients achieved good or excellent results. The mean SCAR-Q scores were 82.07 ± 8.86, and 85.3% evaluated their breasts as good or excellent. The mean overall cost was 5,670.4 ± 1,351.3 USD. The total mean operation time and maturity-stage mean operation time were 234.3 ± 80.4 and 172.55 ± 41.29 min, respectively. According to cumulative sum plot analysis, approximately 18 cases were needed for surgeons to decrease their operation time significantly and complication rate.

CONCLUSION

Single axillary incision reverse-order endoscopic nipple-sparing mastectomy is a safe, less expensive, and efficient surgical technique with reliable intermediate-term oncologic safety. For suitable candidates, the technique with subpectoral implant-based breast reconstruction can provide a good cosmetic outcome.

Deep Edge Detection Methods for the Automatic Calculation of the Breast Contour

Breast cancer conservative treatment (BCCT) is a form of treatment commonly used for patients with early breast cancer. This procedure consists of removing the cancer and a small margin of surrounding tissue, while leaving the healthy tissue intact. In recent years, this procedure has become increasingly common due to identical survival rates and better cosmetic outcomes than other alternatives. Although significant research has been conducted on BCCT, there is no gold-standard for evaluating the aesthetic results of the treatment. Recent works have proposed the automatic classification of cosmetic results based on breast features extracted from digital photographs. The computation of most of these features requires the representation of the breast contour, which becomes key to the aesthetic evaluation of BCCT. State-of-the-art methods use conventional image processing tools that automatically detect breast contours based on the shortest path applied to the Sobel filter result in a 2D digital photograph of the patient. However, because the Sobel filter is a general edge detector, it treats edges indistinguishably, i.e., it detects too many edges that are not relevant to breast contour detection and too few weak breast contours. In this paper, we propose an improvement to this method that replaces the Sobel filter with a novel neural network solution to improve breast contour detection based on the shortest path. The proposed solution learns effective representations for the edges between the breasts and the torso wall. We obtain state of the art results on a dataset that was used for developing previous models. Furthermore, we tested these models on a new dataset that contains more variable photographs and show that this new approach shows better generalization capabilities as the previously developed deep models do not perform so well when faced with a different dataset for testing. The main contribution of this paper is to further improve the capabilities of models that perform the objective classification of BCCT aesthetic results automatically by improving upon the current standard technique for detecting breast contours in digital photographs. To that end, the models introduced are simple to train and test on new datasets which makes this approach easily reproducible.

Clinical assessment of breast symmetry and aesthetic outcome: can 3D imaging be the gold standard?

There is a lack of an accurate standardised objective method to assess aesthetic outcome after breast surgery. In this methodological study, we investigated the intra- and inter-observer reproducibility of breast symmetry and volume assessed using three-dimensional surface imaging (3D-SI), evaluated the reproducibility depending on imaging posture, and proposed a new combined volume-shape-symmetry (VSS) parameter. Images were acquired using the VECTRA XT 3D imaging system, and analysed by two observers using VECTRA Analysis Module. Breast symmetry was measured through the root mean square distance. All women had undergone bilateral risk-reducing mastectomy and immediate breast reconstruction. The reproducibility and correlations of breast symmetry and volume measurements were compared using Bland-Altman's plots and tested with Spearman's rank correlation coefficient. 3D surface images of 58 women were analysed (348 symmetry measurements, 696 volume measurements). The intra-observer reproducibility of breast symmetry measurements was substantial-excellent, the inter-observer reproducibility was substantial, and the inter-posture reproducibility was substantial. For measurements of breast volumes, the intra-observer reproducibility was excellent, the inter-observer reproducibility was moderate-substantial, and the inter-posture reproducibility was substantial-excellent. The intra-observer reproducibility of VSS was excellent while the inter-observer reproducibility was substantial for both observers, independent of posture. There were no statistically strong correlations between breast symmetry and volume differences. The intra-observer reproducibility was found to be substantial-excellent for several 3D-SI measurements independent of imaging posture. However, the inter-observer reproducibility was lower than the intra-observer reproducibility, indicating that 3D-SI in its present form is not a great assessment for symmetry.

A fully automatic framework for evaluating cosmetic results of breast conserving therapy

The breast cosmetic outcome after breast conserving therapy is essential for evaluating breast treatment and determining patient's remedy selection. This prompts the need of objective and efficient methods for breast cosmesis evaluations. However, current evaluation methods rely on ratings from a small group of physicians or semi-automated pipelines, making the processes time-consuming and their results inconsistent. To solve the problem, in this study, we proposed: 1. a fully-automatic Machine Learning Breast Cosmetic evaluation algorithm leveraging the state-of-the-art Deep Learning algorithms for breast detection and contour annotation, 2. a novel set of Breast Cosmesis features, 3. a new Breast Cosmetic dataset consisting 3k+ images from three clinical trials with human annotations on both breast components and their cosmesis scores. We show our fully-automatic framework can achieve comparable performance to state-of-the-art without the need of human inputs, leading to a more objective, low-cost and scalable solution for breast cosmetic evaluation in breast cancer treatment.

'Breast Cosmesis After Breast-Conserving Therapy' Who is the Judge, Patient or Surgeon?

INTRODUCTION

More than 80% of newly diagnosed breast cancers are managed with breast-conserving therapy (BCT). Preservation of cosmetically acceptable breasts is an inherent aim of all breast-conserving efforts-this can, however, be difficult to assess objectively. Compounding this is the difference in perception of breast cosmesis between patients and surgeons. This study compares the concordance of a new subscale-based cosmetic score (TCS) with the patient's perception.

METHOD

Eastern Health Breast and Cancer Centre conducted this study on patients who had completed their BCT and radiotherapy. Participation was voluntary and involved permitting an assessor (breast surgery fellow or consultant) to grade cosmetic outcomes to generate a Total Cosmesis Score (TCS). The patients blinded to this assessment were then asked to complete the postoperative segment of the BCT module of the Breast-Q questionnaire. TCS from surgeon assessment was compared against patient assessment (questions BQ1i and BQ1k specifically). Cohen's kappa was calculated to define the strength of the inter-rater agreement.

RESULTS

One hundred twelve patients with a mean age of 59 (range 27-89) participated in the study. TCS was low in 26% and high in 74% of participants. 76% and 69% of participants were satisfied when answering Breast-Q questions 'How your lumpectomy breast looks?' and 'How you look in the mirror unclothed?' respectively (Cohen's k = 0.464, 95% CI 0.337-0.591, p < 0.01). The agreement between the TCS and the patient assessment was poor (Cohen's k = 0.172, 95% CI - 0.020-2.093, p = 0.067).

CONCLUSION

Cosmetic outcomes scored using TCS by surgeons do not match patient's own assessment of the cosmetic result.

Aesthetic monitoring-based assessment of oncological safety of oncoplastic management of breast cancer: a multi-center research study

BACKGROUND

Oncoplastic Breast surgeries (OBS) in breast cancer have evolved to preserve the cancerous breast rather than its amputation to improve postoperative cosmetic results. The lack of evidence to support the oncological safety and benefits of OBS is questionable. In this study, we evaluate various aspects of oncoplastic surgeries with a focused monitoring of aesthetic results and oncological safety.

METHODS

This was a multi-center observational study focused on the statistics of data collected from cases who underwent oncoplastic surgeries from the cohort of breast cancer candidates at Mansoura University Hospitals/Egypt and King Faisal Medical Complex/KSA from January 2015 to June 2018. All data were analyzed carefully using SPSS v-26.

RESULTS

Eighty cases who underwent different oncoplastic surgeries were included and reviewed for the aesthetic outcome and oncological safety. The recurrence rate was found to be 2.5%. The breast impact treatment scale assessment method was used to analyze the aesthetic outcomes, and average scores were accepted in 90% of patients.

CONCLUSIONS

The oncoplastic breast surgeries are feasible and they had a high rate of oncological safety with the maintenance of good aesthetic outcomes and patient satisfaction.

Oncoplastic breast-conserving surgery for women with primary breast cancer

BACKGROUND

Oncoplastic breast-conserving surgery (O-BCS) involves removing the tumour in the breast and using plastic surgery techniques to reconstruct the breast. The adequacy of published evidence on the safety and efficacy of O-BCS for the treatment of breast cancer compared to other surgical options for breast cancer is still debatable. It is estimated that the local recurrence rate is similar to standard breast-conserving surgery (S-BCS) and also mastectomy, but the aesthetic and patient-reported outcomes may be improved with oncoplastic techniques.

OBJECTIVES

Our primary objective was to assess oncological control outcomes following O-BCS compared with other surgical options for women with breast cancer. Our secondary objective was to assess surgical complications, recall rates, need for further surgery to achieve adequate oncological resection, patient satisfaction through patient-reported outcomes, and cosmetic outcomes through objective measures or clinician-reported outcomes.

SEARCH METHODS

We searched the Cochrane Breast Cancer Group's Specialized Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (via OVID), Embase (via OVID), the World Health Organization's International Clinical Trials Registry Platform and ClinicalTrials.gov on 7 August 2020. We did not apply any language restrictions.

SELECTION CRITERIA

We selected randomised controlled trials (RCTs) and non-randomised comparative studies (cohort and case-control studies). Studies evaluated any O-BCS technique, including volume displacement techniques and partial breast volume replacement techniques compared to any other surgical treatment (partial resection or mastectomy) for the treatment of breast cancer.

DATA COLLECTION AND ANALYSIS

Four review authors performed data extraction and resolved disagreements. We used ROBINS-I to assess the risk of bias by outcome. We performed descriptive data analysis and meta-analysis and evaluated the quality of the evidence using GRADE criteria. The outcomes included local recurrence, breast cancer-specific disease-free survival, re-excision rates, complications, recall rates, and patient-reported outcome measures.

MAIN RESULTS

We included 78 non-randomised cohort studies evaluating 178,813 women. Overall, we assessed the risk of bias per outcome as being at serious risk of bias due to confounding; where studies adjusted for confounding, we deemed these at moderate risk. Comparison 1: oncoplastic breast-conserving surgery (O-BCS) versus standard-BCS (S-BCS) The evidence in the review found that O-BCS when compared to S-BCS, may make little or no difference to local recurrence; either when measured as local recurrence-free survival (hazard ratio (HR) 0.90, 95% confidence interval (CI) 0.61 to 1.34; 4 studies, 7600 participants; very low-certainty evidence) or local recurrence rate (HR 1.33, 95% CI 0.96 to 1.83; 4 studies, 2433 participants; low-certainty evidence), but the evidence is very uncertain due to most studies not controlling for confounding clinicopathological factors. O-BCS compared to S-BCS may make little to no difference to disease-free survival (HR 1.06, 95% CI 0.89 to 1.26; 7 studies, 5532 participants; low-certainty evidence). O-BCS may reduce the rate of re-excisions needed for oncological resection (risk ratio (RR) 0.76, 95% CI 0.69 to 0.85; 38 studies, 13,341 participants; very low-certainty evidence), but the evidence is very uncertain. O-BCS may increase the number of women who have at least one complication (RR 1.19, 95% CI 1.10 to 1.27; 20 studies, 118,005 participants; very low-certainty evidence) and increase the recall to biopsy rate (RR 2.39, 95% CI 1.67 to 3.42; 6 studies, 715 participants; low-certainty evidence). Meta-analysis was not possible when assessing patient-reported outcomes or cosmetic evaluation; in general, O-BCS reported a similar or more favourable result, however, the evidence is very uncertain due to risk of bias in the measurement methods. Comparison 2: oncoplastic breast-conserving surgery (O-BCS) versus mastectomy alone O-BCS may increase local recurrence-free survival compared to mastectomy but the evidence is very uncertain (HR 0.55, 95% CI 0.34 to 0.91; 2 studies, 4713 participants; very low-certainty evidence). The evidence is very uncertain about the effect of O-BCS on disease-free survival as there were only data from one study. O-BCS may reduce complications compared to mastectomy, but the evidence is very uncertain due to high risk of bias mainly resulting from confounding (RR 0.75, 95% CI 0.67 to 0.83; 4 studies, 4839 participants; very low-certainty evidence). Data on patient-reported outcome measures came from single studies; it was not possible to meta-analyse the data. Comparison 3: oncoplastic breast-conserving surgery (O-BCS) versus mastectomy with reconstruction O-BCS may make little or no difference to local recurrence-free survival (HR 1.37, 95% CI 0.72 to 2.62; 1 study, 3785 participants; very low-certainty evidence) or disease-free survival (HR 0.45, 95% CI 0.09 to 2.22; 1 study, 317 participants; very low-certainty evidence) when compared to mastectomy with reconstruction, but the evidence is very uncertain. O-BCS may reduce the complication rate compared to mastectomy with reconstruction (RR 0.49, 95% CI 0.45 to 0.54; 5 studies, 4973 participants; very low-certainty evidence) but the evidence is very uncertain due to high risk of bias from confounding and inconsistency of results. The evidence is very uncertain for patient-reported outcome measures and cosmetic evaluation.

AUTHORS' CONCLUSIONS

The evidence is very uncertain regarding oncological outcomes following O-BCS compared to S-BCS, though O-BCS has not been shown to be inferior. O-BCS may result in less need for a second re-excision surgery but may result in more complications and a greater recall rate than S-BCS. It seems that O-BCS may give better patient satisfaction and surgeon rating for the look of the breast, but the evidence for this is of poor quality, and due to lack of numerical data, it was not possible to pool the results of different studies. It seems O-BCS results in fewer complications compared with surgeries involving mastectomy. Based on this review, no certain conclusions can be made to help inform policymakers. The surgical decision for what operation to proceed with should be made jointly between clinician and patient after an appropriate discussion about the risks and benefits of O-BCS personalised to the patient, taking into account clinicopathological factors. This review highlighted the deficiency of well-conducted studies to evaluate efficacy, safety and patient-reported outcomes following O-BCS.

Breast softness in patients randomised to postmastectomy breast reconstruction with an expander prosthesis or DIEP flap

Background

Objectively measured breast softness in reconstructed breasts and its relation to patients’ subjective satisfaction with breast softness has not yet been investigated. The aim of this study was to evaluate breast softness in patients 1 year following delayed breast reconstruction with an expander prosthesis (EP) or deep inferior epigastric perforator (DIEP) flap, using objective and subjective methods.

Methods

Seventy-three patients were randomised to breast reconstruction with an EP or DIEP flap between 2012 and 2018. Of these, 69 completed objective evaluation at a mean of 25 (standard deviation, SD 9.4) months following breast reconstruction. Objective evaluation included measurements of breast volume, jugulum-nipple distance, clavicular-submammary fold distance, ptosis and Baker scale grading. Breast softness was assessed with applanation tonometry. Subjective evaluation was performed using the BREAST-Q questionnaire.

Results

Objectively, DIEP flaps were significantly softer than EP breast reconstructions. Non-operated contralateral breasts were significantly softer compared with reconstructed breasts. In the subjective evaluation, the median score on the question (labelled 1.h) “How satisfied or dissatisfied have you been with the softness of your reconstructed breast (s)?” was higher in the DIEP flap group corresponding to greater satisfaction in this group. A fair correlation was found between the applanation tonometry and the patient-reported satisfaction with the reconstructed breast’s softness (rs = 0.37).

Conclusions

In terms of breast softness, breast reconstructions with DIEP flaps result in more satisfied patients. Concerning applanation tonometry as an objective tool for softness assessment, future studies on interobserver agreement are warranted.

Level of evidence: Level I, therapeutic study

Considerations in Oncoplastic Surgery

The development of oncoplastic surgery (OPS) is one of the greatest achievements for the treatment of breast cancer. OPS combines oncological resection with plastic surgery techniques in a single procedure to allow the excision of tumors without compromising cosmetic outcome. It allows better aesthetic-functional outcomes and consequently an improvement of the psychological aspects of patients with breast cancer.OPS begins with preoperative design considering breast volume, tumor size, and location and distance from nipple of the tumor, with clinical breast examination and image studies. Various techniques of volume replacement and volume displacement methods described here can help the decision-making process so the best results concerning the aesthetic-functional aspects can be achieved.The outcome measurement of the oncoplastic breast surgery consisted of local recurrence, cosmesis, and patients satisfaction. In OPS for breast cancer patients, aesthetic assessment could be performed by various methods. And questionnaires on quality of life can be applied as a scientific method to assess results. In this chapter, we introduced our results of assessment of both aesthetic and QOL outcomes in OPS patients.

Reliability of the BCCT.core software in evaluation of breast cosmesis - A systematic review

Breast cancer conservative treatment software (BCCT.core) has the potential to provide objective results using digital photographs, thus increasing the reliability, limiting the subjective interpretation and standardising the evaluation of breast cosmesis in patients. The aim of this systematic review was to summarise the empirical evidence regarding the agreement between the BCCT.core and other methods used by health professionals and patients to assess breast cosmesis. The Ovid MEDLINE, Embase, CINAHL, PsycINFO and Scopus databases were systematically searched for studies comparing the agreement between BCCT.core and other methods used to assess breast cosmesis. A total of 14 studies involving 2703 patients were included in the review. In studies where patients undertook self-assessment, the percentage agreement ranged from 69.2% to 74.8% and the kappa values ranged from slight (k = 0.12) to fair agreement. There was a low correlation between the BCCT.core and the Harvard scale when patients assessed cosmetic outcomes using photographs of their breasts (r = 0.165). A 75% and 42.8% agreement was reported in studies where clinicians assessed breast cosmesis by directly visualising the patients' breasts and photographs, respectively. Assessment of breast cosmesis by the expert panel using patient photographs reported a percentage agreement ranging from 25% to 83%. The results of this systematic review demonstrated an overall agreement of fair to moderate between the BCCT.core and the subjective scales used to assess breast cosmesis. However, clinician experience and patient values should be considered in clinical decision-making.

Evaluation of aesthetic outcomes of breast-conserving surgery by the surgeon, nurse, and patients: An analysis

BACKGROUND

Evaluation of the cosmetic outcome after breast-conserving surgery (BCS) differs depending on the evaluator. We performed a clinical trial to examine the differences between assessments of cosmetic outcomes performed by a surgeon, patients, and a nurse as a third party after BCS; the evaluation was performed two times (at 3 months and 9 months after surgery). Similarly, we identified factors most significantly affecting the overall cosmetic outcomes.

METHODS

Sixty-eight patients with primary breast cancer who had undergone BCS between September 2017 and December 2018 were consecutively enrolled in the study. Breast shape, symmetry, hardness, scarring, and overall outcomes were evaluated by a surgeon, patients, and a nurse via a questionnaire.

RESULTS

Intraclass correlation coefficients (ICCs) for the 3- to 9-month comparisons of the surgeon, patients, and nurse were 0.73, 0.64, and 0.29, respectively. The ICCs for the surgeon-patient, nurse-patient, and surgeon-nurse comparisons (3 months/9 months) were 0.49/0.44, 0.34/0.10, and 0.41/0.51, respectively. The partial regression coefficient for shape was 0.45 (p = 0.003)/0.61 (p = 0.001), 0.37 (p = 0.005)/0.50 (p < 0.001), and -0.08 (p = 0.48)/0.58 (p < 0.001) for evaluations performed by the surgeon, patients, and nurse, 3 months and 9 months, respectively.

CONCLUSION

With reproducibility, only moderate agreement was observed between the surgeon and the patients. Breast shape was identified as the most important factor affecting cosmetic outcomes.

A Free Tool for Breast Aesthetic Scale Computation

BACKGROUND

Our work describes the concept of Breast Aesthetic Scale (BAS) as a score for quick and simple objective assessment of results in cosmetic breast surgery. It is obtained by running a software program that we created, based on the previous concept of Objective Breast Cosmesis Scale (OBCS). This was previously described to be used in the context of conservative breast cancer treatment to objectively assess the degree of asymmetry. We describe the implementation of BAS algorithm and study its reproducibility in a set of images.

METHODS

A new multiplatform software was developed by us and named Breast Aesthetic Scale Calculator (BAS-Calc), which can be executed on Windows Mac, and Linux. A set of 25 photographs were studied with this software twice by 2 different surgeons. Intrarater and interrater variability were studied, as well as concordance with categorization by another symmetry assessment software available called Breast Analyzing Tool®.

RESULTS

Concordance among raters was excellent (intraclass correlation coefficient = 0.953; Lin concordance and correlation coefficient = 0.950), as well as intrarater (0.952 and 0.965). Categorization of both systems (Breast Analyzing Tool and BAS-Calc) showed almost perfect concordance (Cohen κ = 0.920).

CONCLUSIONS

Objective estimation of symmetry after breast surgery can be assessed with BAS-Calc. The "symmetric" and "asymmetric" categories are accurately discriminated by this free software, and it can be used by surgeons as a simple method for objective assessment of results in cosmetic breast surgery.

Sub-muscular Reconstruction after NAC Sparing Mastectomy: Direct to Implant Breast Reconstruction with Human ADM Versus Tissue Expander

BACKGROUND

Nipple areola complex (NAC) sparing mastectomy allows good oncological and aesthetic results. The study compares the results, in terms of self-evaluated satisfaction and symmetry, of direct to implant (DTI) sub-muscular breast reconstruction, with the aid of human acellular dermal matrix (ADM) versus two-stage reconstruction with sub-muscular tissue expander, followed by implant.

MATERIALS AND METHODS

This is a retrospective, observational, single-center, non-randomized, case-control study. Inclusion criteria were: unilateral NAC sparing mastectomy at Forlì Hospital between 2014 and 2018; sub-muscular reconstruction; minimum follow-up of 12 months from the reconstructive stage; no history of radiotherapy. Patients were divided into two groups: group A included patients who underwent DTI breast reconstruction with the aid of human ADM; group B were those who underwent a two-stage reconstruction with tissue expander then implant. We collected data on: (1) Self-evaluated satisfaction by Breast Q questionnaire (scores from 0 to 100). (2) Observer-evaluated symmetry. Bi-dimensional photographs were collected and evaluated by 11 breast surgeons blinded to each other, who assigned a score for symmetry (from 0 to 10). (3) Symmetry of anthropometric measures collected by hand and volume estimated by Breast V application.

RESULTS

Group A included 28 patients; group included B 26 patients. Breast-Q questionnaires reported the following results: satisfaction with breasts in group A 65 ± 12 versus group B 68 ± 14; satisfaction with outcome in group A 88 ± 16 versus group B 93 ± 11; psychosocial well-being in group A 71 ± 20 versus group B 76 ± 17; sexual well-being in group A 63 ± 26 versus group B 60 ± 13; physical well-being in group A 68 ± 15 versus group B 60 ± 12. The average symmetry breast score assigned to group A was 6.9, versus group B 7.2. Regarding the anthropometric measures in group A, the differences between right and left were major to those in group B. Regarding breast volume, the mean difference between right and left in group A was 31.89 cc ± 24.97, whereas in group B was 25.46 cc ± 23.59.

CONCLUSION

Our data show better symmetry and better psychosocial well-being in the two-stage reconstruction, and higher satisfaction with sexual and physical well-being in DTI reconstructions. These aspects should be discussed with the patient while collecting the informed consent.

Quantitative 3-Dimensional Photographic Assessment of Breast Cosmesis After Whole Breast Irradiation for Early Stage Breast Cancer: A Secondary Analysis of a Randomized Clinical Trial

Purpose

Our purpose was to use 3-dimensional (3D) surface photography to quantitatively measure breast cosmesis within the framework of a randomized clinical trial of conventionally fractionated (CF) and hypofractionated (HF) whole breast irradiation (WBI); to identify how 3D measurements are associated with patient- and physician-reported cosmesis; and to determine whether objective measures of breast symmetry varied by WBI treatment arm or transforming growth factor β 1 (TGFβ1) status.

Methods and Materials

From 2011 to 2014, 287 women age ≥40 with ductal carcinoma in situ or early-stage invasive breast cancer were enrolled in a multicenter trial and randomized to HF-WBI or CF-WBI with a boost. Three-dimensional surface photography was performed at 3 years posttreatment. Patient-reported cosmetic outcomes were recorded with the Breast Cancer Treatment Outcome Scale. Physician-reported cosmetic outcomes were assessed by the Radiation Therapy Oncology Group scale. Volume ratios and 6 quantitative measures of breast symmetry, termed F1-6C, were calculated using the breast contour and fiducial points assessed on 3D surface images. Associations between all metrics, patient- and physician-reported cosmesis, treatment arm, and TGFβ1 genotype were performed using the Kruskal-Wallis test and multivariable logistic regression models.

Results

Among 77 (39 CF-WBI and 38 HF-WBI) evaluable patients, both patient- and physician-reported cosmetic outcomes were significantly associated with the F1C vertical symmetry measure (both P < .05). Higher dichotomized F1C and volumetric symmetry measures were associated with improved patient- and physician-reported cosmesis on multivariable logistic regression (both P ≤ .05). There were no statistically significant differences in vertical symmetry or volume measures between treatment arms. Increased F6C horizontal symmetry was observed in the CF-WBI arm (P = .05). Patients with the TGFβ1 C-509T variant allele had lower F2C vertical symmetry measures (P = .02).

Conclusions

Quantitative 3D image-derived measures revealed comparable cosmetic outcomes with HF-WBI compared with CF-WBI. Our findings suggest that 3D surface imaging may be a more sensitive method for measuring subtle cosmetic changes than global patient- or physician-reported assessments.

Use of Symmetry Assessment Methods in the Context of Breast Surgery

BACKGROUND

Different procedures are available to help clinicians evaluate symmetry and cosmetic results in an objective manner after conservative breast cancer surgery. However, there are no similar methods in esthetic breast surgery, where the subjective assessment of the surgeon or the patient is usually considered the gold standard. The aim of this study is to evaluate the application of four software programs in the context of esthetic breast surgery and contrast their results with those of the subjective evaluation by a series of healthcare professionals.

MATERIALS AND METHODS

Sixty cosmetic breast surgery images were studied using four software programs considered appropriate for the objective evaluation (BCCT3.core^®, Breast Analyzing Tool^®, Objective Breast Cosmesis Scale^® and GBAI-Global Breast Asymmetry Index^®). The same cases were assessed by a group of 100 health professionals through an online survey as a subjective evaluation method.

RESULTS

Concordance among participants was high (κ = 0.753) as well as between three of the objective methods (BSI, OBCS, GBAI), but not with the BCCT parameter. There was no association between objective and subjective methods studied by the survey, according to the logistic regression model. The "symmetry" and "asymmetry" categories were accurately distinguished by the objective methods.

CONCLUSIONS

Objective evaluation in esthetic breast surgery has less variability than subjective assessment, and the estimation is possible through certain software previously restricted to conservative breast cancer surgery.

Patient satisfaction after breast cancer surgery : A prospective clinical trial

BACKGROUND

This study investigated the impact of curative breast cancer surgery on patient satisfaction concerning cosmetic results and quality of life (QoL).

METHODS

In this study 61 participants completed questionnaires to evaluate their QoL and patient satisfaction with cosmetic results following breast cancer surgery. Cosmetic outcomes were evaluated by the breast surgeon and an independent breast specialist using the Harris scale and the breast analyzing tool (BAT).

RESULTS

Of the participants 71% completed all 4 follow-up visits, 38 (62%) patients received breast-conserving therapy (BCT) and 23 (38%) received a mastectomy. Surgery-associated complications arose in 2.6% of the patients who received BCT and 17.4% of patients who received a mastectomy. No significant differences in QoL between BCT patients and mastectomy patients were observed immediately after surgery, or after 6 and 12 months. Breast asymmetry, measured using the BAT score, and QoL scores were worst immediately after surgery. The surgeon rated the cosmetic results as better compared to the independent breast expert (p = 0.001). Furthermore, patients aged over 60 years old were less satisfied with the cosmetic outcome compared to younger patients at the time of discharge (p = 0.024). Patients who received a mastectomy were less satisfied when the resected volume was higher.

CONCLUSION

Patient satisfaction was lowest immediately after surgery but improved during the following months, despite continued breast asymmetry. For mastectomy patients, a lower resected volume led to a higher satisfaction with cosmetic results. Satisfaction is subjective and cannot be determined from the esthetic satisfaction of the surgeon or using an objective tool measuring breast asymmetry.

kOBCS©: a novel software calculator program of the Objective Breast Cosmesis Scale (OBCS)

PURPOSE

The Objective Breast Cosmesis Scale (OBCS) is an objective method that documents the aesthetic changes in breast cancer patients. This work evaluates the kOBCS© software (http://www.kobcs.info) which simplifies the estimation of the OBCS values.

METHODS

Five schematic drawings were photographed and imported into the kOBCS©. Thirty photos of breast cancer patients were imported into kOBCS©; 20 users (experts and non-experts) evaluated the photographs on two different settings. Subjective evaluation was performed using the Harvard breast cosmesis scale.

RESULTS

There was a highly significant correlation between the OBCS values based on hand measurements and the values estimated by kOBCS© (r = 0.997, P < 0.001). Agreement among the users using the kOBCS© was strong with high statistical significance (ICC = 0.846, P < 0.001, 95% CI 0.774-0.910, Cronbach's alpha = 0.991). Results of the subjective analyses and mean OBCS values as estimated by kOBCS© correlated significantly (r = 0.961, P < 0.001).

CONCLUSIONS

The kOBCS© is a reliable and reproducible easy-to-use software for reporting breast cosmesis following breast-conserving therapy.

Evolution, current challenges, and future possibilities in the objective assessment of aesthetic outcome of breast cancer locoregional treatment

The Breast Cancer overall survival rate has raised impressively in the last 20 years mainly due to improved screening and effectiveness of treatments. This increase in survival paralleled the awareness over the long-lasting impact of the side effects of treatments on patient quality of life, emphasizing the motto “a longer but better life for breast cancer patients”. In breast cancer more strikingly than in other cancers, besides the side effects of systemic treatments, there is the visible impact of surgery and radiotherapy on patients’ body image. This has sparked interest on the development of tools for the aesthetic evaluation of Breast Cancer locoregional treatments, which evolved from manual, subjective approaches to computerized, automated solutions. However, although studied for almost four decades, past solutions were not mature enough to become a standard.

Recent advancements in machine learning have inspired trends toward deep-learning-based medical image analysis, also bringing new promises to the field of aesthetic assessment of locoregional treatments. In this paper, a review and discussion of the previous state-of-the-art methods in the field is conducted and the extracted knowledge is used to understand the evolution and current challenges. The aim of this paper is to delve into the current opportunities as well as motivate and guide future research in the aesthetic assessment of Breast Cancer locoregional treatments.

•

Past, present and future of objective assessment of aesthetic outcome of breast cancer treatments.

•

Critical discussion of the role and impact of deep-learning-based methodologies in the field.

Recommendation for future efforts in the objective assessment of aesthetic outcome of breast cancer treatments.

A prospective comparison of subjective and objective assessments of cosmetic outcomes following breast brachytherapy

Purpose

We evaluated agreement between subjective and objective methods of cosmesis scoring in an accelerated partial breast irradiation (APBI) cohort.

Material and methods

Consecutive women treated with APBI using interstitial brachytherapy reported for clinical follow-up every 6 months. Single cross-sectional assessment of the breast cosmesis was done by a radiation oncologist (subjective method) using Harvard scale and by photographic assessment using BCCT.core (Breast Cancer Conservative Treatment. Cosmetic results, version 3.1) software (objective method) at 18-36 months post-APBI. The agreement between subjective and objective methods for the overall score as well as individual subjective/objective subdomains was computed using kappa statistics. ANOVA was used to test the correlation between objective indices and subjective subdomains.

Results

The agreement between the subjective (physician) and objective assessment was good with a kappa of 0.673. Overall, 77 (98.7%) patients were satisfied with the overall outcomes of breast conservation therapy. The kappa agreement between physician and patient scoring was 0.457 (95% CI: 0.240-0.674). Among the subjective subdomains, location of the nipple areola complex (NAC) had good agreement with both the overall subjective and objective score, with the kappa of 0.778 and 0.547, respectively. In the objective indices, BCE (breast compliance evaluation), LBC (lower breast contour), and UNR (unilateral nipple retraction) correlated significantly with the subjective subdomains: location of the NAC, breast size, and shape (p < 0.05 for all indices).

Conclusions

Good agreement exists for overall cosmetic outcomes measured by subjective and objective methods. Location of the NAC, breast size and shape are the most important parameters determining cosmetic outcomes irrespective of the method of assessment.

Cosmetic assessment in brachytherapy (interventional radiotherapy) for breast cancer: A multidisciplinary review

PURPOSE

This review was to focus on breast brachytherapy cosmetic assessment methods state of the art and to define the advantages and disadvantages related to.

METHODS AND MATERIALS

We conducted a literature review of the major experience on breast brachytherapy cosmetic assessment methods in several databases (PubMed, Scopus, and Google Scholar databases). To identify the relevant works, a task force screened citations at title and abstract level to identify potentially relevant paper. An expert board reviewed and approved the text. The assessment systems were classified into three main groups: (1) the Oncological Toxicity Scales, (2) the Independent Patients Perspective Measures, (3) the Patient-Related Outcome Measures. Each cosmetic assessment method was evaluated following six parameters: (1) anatomical site, (2) advantages, (3) disadvantages, (4) subjective/objective, (5) quantitative/qualitative, (6) computers or pictures needs.

RESULTS

Eleven assessment methods were selected. Three methods were classified as Oncological Toxicity Scale, six in the Independent Patients Perspective Measures classification, and two as Patient-Related Outcome Measures. Six methods are subjective, while eight are objective. Four systems are classified as quantitative, four as qualitative while three both. Five systems need informatics support. Moreover, each method was discussed individually reporting the main characteristics and peculiarities.

CONCLUSIONS

Cosmesis is one major end point for the patient who has a malignancy of low lethal potential. In modern personalized medicine, there is a need for standardized cosmetic outcome assessments to analyze and compare the results of treatments. No gold standard methods currently exist. The result of this review is to summarize the various cosmesis methods, defining the strengths and weaknesses of each one and giving a line in research and clinical practice.

Breast Shape Analysis With Curvature Estimates and Principal Component Analysis for Cosmetic and Reconstructive Breast Surgery

Background

Breast shape is defined utilizing mainly qualitative assessment (full, flat, ptotic) or estimates, such as volume or distances between reference points, that cannot describe it reliably.

Objectives

The authors quantitatively described breast shape with two parameters derived from a statistical methodology denominated by principal component analysis (PCA).

Methods

The authors created a heterogeneous dataset of breast shapes acquired with a commercial infrared 3-dimensional scanner on which PCA was performed. The authors plotted on a Cartesian plane the two highest values of PCA for each breast (principal components 1 and 2). Testing of the methodology on a preoperative and posttreatment surgical case and test-retest was performed by two operators.

Results

The first two principal components derived from PCA characterize the shape of the breast included in the dataset. The test-retest demonstrated that different operators obtain very similar values of PCA. The system is also able to identify major changes in the preoperative and posttreatment stages of a two-stage reconstruction. Even minor changes were correctly detected by the system.

Conclusions

This methodology can reliably describe the shape of a breast. An expert operator and a newly trained operator can reach similar results in a test/re-testing validation. Once developed and after further validation, this methodology could be employed as a good tool for outcome evaluation, auditing, and benchmarking.

Level of Evidence 4

Multi-institutional evaluation of the reproducibility and the accuracy of the objective breast cosmesis scale

PURPOSE

The aim of the present work is to assess the Objective Breast Cosmesis Scale (OBCS) in a patient cohort that was treated in two hospitals. Their treatment-related cosmetic changes were recorded on nonstandardized photographs.

METHODS AND MATERIALS

Nineteen female patients were enrolled in two radiation oncology centers (Nice, France, and Perugia, Italy). All patients had undergone breast-conserving surgery (BCS) and received adjuvant accelerated partial breast irradiation using interstitial fractionated multicatheter high-dose-rate brachytherapy. One photograph before and another after accelerated partial breast irradiation was taken for each patient to record changes in breast cosmesis. Using the OBCS, before and after photographs were analyzed by measuring distances between anatomic features. OBCS scores from four doctors (two males [one radiation oncologist and one post-grad trainee] and two females [one radiation oncologist and one post-grad trainee]) were compared.

RESULTS

Agreement was high between trainees and specialist, and males and females before and after treatment. The intraclass correlation coefficient ranged from 0.867 to 0.950 before treatment and from 0.876 to 0.952 afterward. The coefficient of variation ranged from 12% to 26.5% before treatment, and from 13% to 21.4% afterward.

CONCLUSIONS

The OBCS is easy, time-efficient, reproducible, cost-effective, and reliable. Its potential practical applications merit further investigation in future studies.

Cosmetic outcome as rated by patients, doctors, nurses and BCCT.core software assessed over 5 years in a subset of patients in the TARGIT-A Trial

Background

The purpose of this research was to assess agreement between four rating systems of cosmetic outcome measured in a subset of patients with early breast cancer participating in the randomised TARGIT-A trial. TARGIT-A compared risk-adapted single-dose intra-operative radiotherapy (TARGIT-IORT) to whole breast external beam radiotherapy (EBRT).

Methods

Patients, their Radiation Oncologist and Research Nurse completed a subjective cosmetic assessment questionnaire before radiotherapy and annually thereafter for five years. Objective data previously calculated by the validated BCCT.core software which utilizes digital photographs to score symmetry, colour and scar was also used. Agreement was assessed by the Kappa statistic and longitudinal changes were assessed by generalized estimating equations.

Results

Overall, an Excellent-Good (EG) cosmetic result was scored more often than a Fair-Poor (FP) result for both treatment groups across all time points, with patients who received TARGIT-IORT scoring EG more often than those who received EBRT however this was statistically significant at Year 5 only. There was modest agreement between the four rating systems with the highest Kappa score being moderate agreement which was between nurse and doctor scores at Year 1 with Kappa = 0.46 (p < 0.001), 95% CI (0.24, 0.68).

Conclusion

Despite similar overall findings between treatment groups and rating systems, the inter-rater agreement was only modest. This suggests that the four rating systems utilized may not necessarily be used interchangeably and it is arguable that for an outcome such as cosmetic appearance, the patient’s point of view is the most important.

Batwing Mastopexy as Oncoplastic Surgical Approach to Periareolar Tumors in Upper Quadrants

Aims and background

Batwing mastopexy (BWM) is an oncoplastic technique most commonly used in the treatment of 12 o'clock periareolar tumors. The aim of this study was to assess the early cosmetic results of BWM performed for periareolar lesions located in the upper quadrants, i.e. from 10 to 2 o'clock position.

Methods and study design

A prospective analysis of a preliminary group of 35 women with periareolar intraductal or invasive breast cancer in the upper quadrants was done. All patients underwent wide lumpectomy with clear margins followed by BWM in order to obtain favorable cosmesis. For invasive cancers axillary biopsy or dissection was performed by separate incision. Cosmetic outcome was assessed 4 weeks after surgery by the patient with reference to breast shape, nipple-areola complex (NAC) position and scar arrangement. The result was rated as poor, medium or good for each parameter.

Results

There were no poor ratings of cosmetic outcome. The result was rated as medium by 5 women (14%) regarding breast shape and by 3 regarding NAC position (9%). The remaining women evaluated these parameters as good (86% and 91%, respectively). In contrast, scar arrangement was assessed as good by 26 patients (74%), medium by 8 (23%), and poor by 1 (3%). All women rating scar arrangement as other than good had a lesion located in the upper lateral quadrant. Considering the reasons for the relatively low scar acceptance by these women, the only important cause of disappointment was the placement of one of the radial parts of the scar in the area of decolletage in the upper medial quadrant.

Conclusions

BWM allows to achieve favorable breast shape and NAC position for lesions located in the upper quadrants regardless of the medial or lateral side. However, when performed in the lateral quadrant it produces a scar that can be hard to accept for some women.

Body image dissatisfaction in patients undergoing breast reconstruction: Examining the roles of breast symmetry and appearance investment

OBJECTIVE

Reconstruction as part of treatment for breast cancer is aimed at mitigating body image concerns after mastectomy. Although algorithms have been developed to objectively assess breast reconstruction outcomes, associations between objectively quantified breast aesthetic appearance and patient-reported body image outcomes have not been examined. Further, the role of appearance investment in explaining a patient's body image is not well understood. We investigated the extent to which objectively quantified breast symmetry and patient-reported appearance investment were associated with body image dissatisfaction in patients undergoing cancer-related breast reconstruction.

METHODS

Breast cancer patients in different stages of reconstruction (n = 190) completed self-report measures of appearance investment and body image dissatisfaction. Vertical extent and horizontal extent symmetry values, which are indicators of breast symmetry, were calculated from clinical photographs. Associations among breast symmetry, appearance investment, body image dissatisfaction, and patient clinical factors were examined. Multi-variable regression was used to evaluate the extent to which symmetry and appearance investment were associated with body image dissatisfaction.

RESULTS

Vertical extent symmetry, but not horizontal extent symmetry, was associated with body image dissatisfaction. Decreased vertical extent symmetry (β = -.19, P < .05) and increased appearance investment (β = .45, P < .001) were significantly associated with greater body image dissatisfaction while controlling for clinical factors.

CONCLUSIONS

Breast symmetry and patient appearance investment both significantly contribute to an understanding of patient-reported body image satisfaction during breast reconstruction treatment.

The potential role of three-dimensional surface imaging as a tool to evaluate aesthetic outcome after Breast Conserving Therapy (BCT)

PURPOSE

To establish whether objective measurements of symmetry of volume and shape using three-dimensional surface imaging (3D-SI) can be used as surrogate markers of aesthetic outcome in patients who have undergone breast conserving therapy (BCT).

METHODS

Women who had undergone unilateral BCT in the preceding 1-6 years were invited to participate. Participants completed a satisfaction questionnaire (BREAST-Q) and underwent 3D-SI. Volume and surface symmetry were measured on the images. Assessment of aesthetic outcome was undertaken by a panel of clinicians. The Kruskal-Wallis test was used to assess the relationship between volume and shape symmetry measurements with the panel score. Spearman's rho correlations were used to assess the relationship between the measurements and patient satisfaction.

RESULTS

200 women participated. Median volume symmetry was 87% (IQR 78-93) and shape symmetry was 5.9 mm (IQR 4.2-8.0). The participants were grouped according to panel assessment of aesthetic outcome (poor, fair, good, excellent) and the median volume and shape symmetry was calculated for each group. Volume symmetry significantly differed between the groups. Post hoc pairwise comparisons demonstrated that these differences existed between panel scores of fair versus good and good versus excellent. Median shape symmetry also differed according to patient panel groups with four significant pairwise comparisons between poor versus good, poor versus excellent, fair versus good and fair versus excellent. There was a significant but weak correlation of both volume symmetry and surface asymmetry with BREAST-Q scores (correlation coefficients 0.187 and -0.229, respectively).

CONCLUSION

Breast volume and shape symmetry are both associated with panel assessment scores and patient satisfaction. The objective volume and shape symmetry measures were strongly associated with panel assessment scores, such that a 3D-SI tool could replace panel assessment as a faster and more objective method of evaluating aesthetic outcomes.

Objective breast symmetry analysis with the breast analyzing tool (BAT): improved tool for clinical trials

PURPOSE

Objective cosmetic analysis is important to evaluate the cosmetic outcome after breast surgery or breast radiotherapy. For this purpose, we aimed to improve our recently developed objective scoring software, the Breast Analyzing Tool (BAT^®).

METHODS

A questionnaire about important factors for breast symmetry was handed out to ten experts (surgeons) and eight non-experts (students). Using these factors, the first-generation BAT^® software formula has been modified and the breast symmetry index (BSI) from 129 women after breast surgery has been calculated by the first author with this new BAT^® formula. The resulting BSI values of these 129 breast cancer patients were then correlated with subjective symmetry scores from the 18 observers using the Harris scale. The BSI of ten images was also calculated from five observers different from the first author to calculate inter-rater reliability. In a second phase, the new BAT^® formula was validated and correlated with subjective scores of additional 50 women after breast surgery.

RESULTS

The inter-rater reliability analysis of the objective evaluation by the BAT^® from five individuals showed an ICC of 0.992 with almost no difference between different observers. All subjective scores of 50 patients correlated with the modified BSI score with a high Pearson correlation coefficient of 0.909 (p < .001) which was better compared to the old software (r = 0.769; p < .001).

CONCLUSIONS

The modified BAT^® software improves the correlation between subjective and objective BSI values, and may be a new standard for trials evaluating breast symmetry.

Quantitative Assessment of Breast Cosmetic Outcome After Whole-Breast Irradiation

PURPOSE

To measure, by quantitative analysis of digital photographs, breast cosmetic outcome within the setting of a randomized trial of conventionally fractionated (CF) and hypofractionated (HF) whole-breast irradiation (WBI), to identify how quantitative cosmesis metrics were associated with patient- and physician-reported cosmesis and whether they differed by treatment arm.

METHODS AND MATERIALS

From 2011 to 2014, 287 women aged ≥40 with ductal carcinoma in situ or early invasive breast cancer were randomized to HF-WBI (42.56 Gy/16 fractions [fx] + 10-12.5 Gy/4-5 fx boost) or CF-WBI (50 Gy/25 fx + 10-14 Gy/5-7 fx). At 1 year after treatment we collected digital photographs, patient-reported cosmesis using the Breast Cancer Treatment and Outcomes Scale, and physician-reported cosmesis using the Radiation Therapy Oncology Group scale. Six quantitative measures of breast symmetry, labeled M1-M6, were calculated from anteroposterior digital photographs. For each measure, values closer to 1 imply greater symmetry, and values closer to 0 imply greater asymmetry. Associations between M1-M6 and patient- and physician-reported cosmesis and treatment arm were evaluated using the Kruskal-Wallis test.

RESULTS

Among 245 evaluable patients, patient-reported cosmesis was strongly associated with M1 (vertical symmetry measure) (P<.01). Physician-reported cosmesis was similarly correlated with M1 (P<.01) and also with M2 (vertical symmetry, P=.01) and M4 (horizontal symmetry, P=.03). At 1 year after treatment, HF-WBI resulted in better values of M2 (P=.02) and M3 (P<.01) than CF-WBI; treatment arm was not significantly associated with M1, M4, M5, or M6 (P≥.12).

CONCLUSIONS

Quantitative assessment of breast photographs reveals similar to improved cosmetic outcome with HF-WBI compared with CF-WBI 1 year after treatment. Assessing cosmetic outcome using these measures could be useful for future comparative effectiveness studies and outcome reporting.

Comparison of Aesthetic Outcomes Between Vertical and Horizontal Flap Insets in Breast Reconstruction with the TRAM or DIEP Flaps

BACKGROUND

Tissue transfer, such as use of the transverse rectus abdominis myocutaneous (TRAM) or deep inferior epigastric artery perforator (DIEP) free flaps, is considered a standard method. However, outcomes may vary among inset methods. Here we compared the aesthetic outcomes of breast reconstructions using vertical and horizontal flap inset methods.

METHODS

We, respectively, reviewed 274 patients who underwent unilateral post-mastectomy breast reconstruction using TRAM or DIEP free flaps between April 2006 and December 2013. Photographs (frontal and bilateral oblique views) obtained 6 months post-operatively were evaluated. Symmetry scores and regional volume discrepancy scores were compared between the vertical and horizontal inset groups. Symmetry scores were adjusted for 11 potential confounding factors on multivariate regression analysis.

RESULTS

The vertical inset method was associated with higher total symmetry scores, projection, and ptotic naturalness scores. On multivariate regression analysis, the inset method was an independent predictor of outcomes. Regional volume discrepancy score analysis showed a greater tendency for more symmetrical volumes in the upper, medial, and lateral poles with the vertical inset.

CONCLUSION

The flap inset method is one of the key determinants of aesthetic breast reconstruction outcomes. The vertical inset method was associated with superior aesthetic outcomes and enabled balanced distribution of flap volume to the four poles of the breast.

Single dose IOERT versus whole breast irradiation : Cosmetic results in breast-conserving therapy

BACKGROUND

Scarce data are available about the cosmetic result of single dose intraoperative electron radiotherapy (IOERT) in breast-conserving radiotherapy.

METHODS AND MATERIALS

We included 71 breast cancer patients. Breast-conserving surgery and sentinel node procedure had started almost 3 years earlier. Subsequently, 26 patients were treated with IOERT and 45 patients received postoperative whole breast irradiation (WBI). For both groups we determined seven dimensionless asymmetry features. We compared the subjectively and the objectively derived cosmetic scores with each other.

RESULTS

For four asymmetry features we noted significantly smaller differences for patients treated with IOERT when compared to those treated with WBI: relative breast contour difference, relative breast area difference and relative breast overlap difference. After correcting for excision volume a significant difference was noticed also for relative lower breast contour. For the IOERT group the cosmetic scores "excellent or good" as determined by each patient and one physician were 88 and 96 %, respectively. When the overall cosmetic scores for patients treated with IOERT and WBI were compared to those of the objectively derived scores, there was a fair level of agreement.

CONCLUSION

For patients treated with IOERT we noted less asymmetry and high rates of "good or excellent" subjectively derived cosmetic scores. The level of agreement between the subjectively and the objectively derived cosmetic scores was limited. Due to the small sample size and the design of the study no definitive conclusions can be drawn.

The breast cancer conservative treatment. Cosmetic results - BCCT.core - Software for objective assessment of esthetic outcome in breast cancer conservative treatment: A narrative review

BACKGROUND AND OBJECTIVE

Cosmetic outcome of breast cancer conservative treatment (BCCT) remains without a standard evaluation method. Subjective methods, in spite of their low reproducibility, continue to be the most frequently used. Objective methods, although more reproducible, seem unable to translate all the subtleties involved in cosmetic outcome. The breast cancer conservative treatment cosmetic results (BCCT.core) software was developed in 2007 to try to overcome these pitfalls. The software is a semi-automatic objective tool that evaluates asymmetry, color differences and scar visibility using patient's digital pictures. The purpose of this work is to review the use of the BCCT.core software since its availability in 2007 and to put forward future developments.

METHODS

All the online requests for BCCT.core use were registered from June 2007 to December 2014. For each request the department, city and country as well as user intention (clinical use/research or both) were questioned. A literature search was performed in Medline, Google Scholar and ISI Web of Knowledge for all publications using and citing "BCCT.core".

RESULTS

During this period 102 centers have requested the software essentially for clinical use. The BCCT.core software was used in 19 full published papers and in 29 conference abstracts.

CONCLUSIONS

The BCCT.core is a user friendly semi-automatic method for the objective evaluation of BCCT. The number of online requests and publications have been steadily increasing turning this computer program into the most frequently used tool for the objective cosmetic evaluation of BCCT.

In Search of a Gold Standard Scoring System for the Subjective Evaluation of Cosmetic Outcomes Following Breast-Conserving Therapy

The absence of a widely accepted method for aesthetic evaluation following breast-conserving surgery for breast cancer limits the ability to evaluate cosmetic outcomes. In this study, two different panel scoring approaches were compared in an attempt to identify a gold standard scoring system for subjectively assessing cosmetic outcomes following breast-conserving therapy. Standardized photographs of each participant were evaluated independently by twelve health care professionals involved in breast cancer diagnosis and treatment using the Danoff four-point scale. Individual Danoff scores were combined using two methods, a random sample "three-panel" score and an iterative "Delphi-panel" score, in order to create a final cosmetic score for each patient. Agreement between these two aggregative approaches was assessed with a weighted kappa (wk) statistic. Patient and professional recruitment occurred at two separate tertiary care multi-disciplinary breast health centers. Women with unilateral breast cancer who underwent breast-conserving therapy (segmental mastectomy or lumpectomy and radiotherapy) and were at least 2 years after radiotherapy were asked to participate. Ninety-seven women were evaluated. The Delphi approach required three rounds of evaluation to obtain greater than 50% agreement in all photographs. The wk statistic between scores generated from the "three-panel" and "Delphi-panel" approaches was 0.80 (95% CI: 0.71-0.89), thus demonstrating substantial agreement. Evaluation of cosmetic outcomes following breast-conserving therapy using a "three-panel" and "Delphi-panel" score provide similar results, confirming the reliability of either approach for subjective evaluation. Simplicity of use and interpretation favors the "three-panel" score. Future work should concentrate on the integration of the three-panel score with objective and patient-reported scales to generate a comprehensive cosmetic evaluation platform.

Cosmetic evaluation methods adapted to asian patients after breast-conserving surgery and examination of the necessarily elements for cosmetic evaluation

Purpose

Although various strategies have been reported, there are no defined criteria for cosmetic evaluation methods after breast-conserving surgery (BCS). Since Asians tend to have smaller breasts, indistinct inframammary folds, and conspicuous scars, differences in the cosmetic results are expected. So we examined two subjective methods and one objective method to determine the differences, and elements necessary for a cosmetic evaluation after BCS.

Methods

Frontal photographs of 190 Japanese were evaluated using the Harris scale (Harris) and the evaluation method proposed by the Japanese Breast Cancer Society Sawai group (Sawai group) as the subjective methods, and the Breast Cancer Conservation Treatment cosmetic results (BCCT.core) as the objective method, respectively. In order to examine the necessary elements for developing a new ideal method, 100 out of 190 were selected and assessed separately by six raters using both the Harris and modified Sawai group methods in the observer assessment. The correlation between the two methods was examined using the Spearman rank-correlation coefficient.

Results

The results of the BCCT.core and the other two methods were clearly different. In the observer assessment, the consensuses of the six raters were evaluated as follows: 27, 27, 26, and 20 cases were evaluated as "excellent," "good," "fair," and "poor," respectively. For the Spearman rank-correlation coefficient, values higher than 0.7 indicated a strong correlation, as seen by the values of 0.909 for the breast shape and 0.345 for the scar. The breast shape accounted for the most significant part of the evaluation, and the scar had very little correlation.

Conclusion

In this study, we recognized a clear difference between the subjective and objective evaluation methods, and identified the necessary elements for cosmetic evaluation. We would like to continue developing an ideal cosmetic evaluation that is similar to subjective one and is independent from raters.

A cosmesis outcome substudy in a prospective, randomized trial comparing radioguided seed localization with standard wire localization for nonpalpable, invasive, and in situ breast carcinomas

BACKGROUND

The primary study objective was to compare the cosmetic result of radioguided seed localization (RSL) with wire localization (WL).

METHODS

A subgroup of patients enrolled in a multicentered, randomized trial comparing WL with RSL participated. Frontal photographs were taken 1 and 3 years postsurgery. The European Organization for Research and Treatment of Cancer Cosmetic Rating System was used to evaluate cosmesis outcomes by the patient and a panel of 5 raters.

RESULTS

The study enrolled 73 patients (WL, n = 38; RSL, n = 35). Most patients rated their overall cosmesis as "excellent" or "good" (76% WL, 80% RSL). Patient and panel ratings on all cosmetic outcomes were similar between groups. Multivariable regression for overall cosmesis found larger specimen volume and reoperation to be predictors of worse ratings.

CONCLUSIONS

All cosmetic outcomes assessed were similar after WL and RSL. The comparable outcomes may reflect similar reoperation rates and volumes of excision between groups.

The use of real-time digital video in the assessment of post-operative outcomes of breast reconstruction

INTRODUCTION

Outcome measures of breast reconstruction have used panel assessment of photographs. This provides limited information to the assessor as these images are static.. The aim of this study was to assess whether the use of digital video was a valid assessment tool and to compare its use against photography.

METHODS

35 patients post-reconstruction underwent photography, digital video capture and completed Breast Cancer Treatment Outcomes Scale (BCTOS) questionnaires. The photographs/video clips were randomised and shown to a 21 member panel. Opinions on aesthetic aspects of the reconstruction were assessed using the BCTOS and Harris scale. Panel inter-rater agreement and patient-panel correlation was assessed using Kendall's Coefficient of Concordance and Spearman's rank correlation tests respectively.

RESULTS

There was a "moderate" degree of inter-rater agreement amongst panel members in all categories. Greater agreement occurred using video footage to assess overall cosmesis (0.548 vs 0.507) and shape (0.505 vs 0.486). Video showed a greater degree of correlation with patient self-assessment scores in comparison to photography (0.311 vs 0.281).

CONCLUSION

Video footage coupled with panel assessment is a valid method of assessing post-operative outcomes of breast reconstruction and appears superior to still photographs in terms of inter-rater agreement and correlation with patient self-assessment.
