Long-term results of oncoplastic breast surgery with latissimus dorsi flap reconstruction: a pilot study of the objective cosmetic results and patient reported outcome

Surgical and patient-reported outcomes in an Asian female population with or without adjuvant radiotherapy after immediate free perforator flap breast reconstruction: A retrospective review

Background

The majority of English literature has reported on the somewhat conflicted outcomes of the effect of radiotherapy on immediate breast reconstruction. However, data specifically related to patients of Asian descent has been scarce. This retrospective study aims to shed light on this topic to aid in the management of this group of patients.

Methods

All patients who received immediate free perforator flap-based breast reconstruction under a single surgeon over a 10-year period were included in the study. Patient characteristics, oncological and surgical data were collected. Patients were divided into post-mastectomy radiotherapy (PMRT) and non-PMRT groups. The final aesthetic outcome was assessed by a surgeon-reported outcome questionnaire. Patient satisfaction and psychological outcomes were assessed using validated patient-reported outcome (PRO) questionnaire (BREAST-Q), breast reconstruction, and postoperative module.

Results

A total of 101 women, with an average age of 44.7 ± 8.4 underwent perforator flap-based reconstruction. Fifteen patients received PMRT, with remaining 86 patients in the non-PMRT group. The mean duration of follow-up was over 5 years (p = 0.514). The recurrence rate was acceptable in the PMRT group (3/15, p = 0.129). There were no significant differences in complication rates between the two groups (p = 1.000). The aesthetic outcomes were comparable (p = 0.342). PRO appears to be lower in the PMRT group.

Conclusions

Immediate breast reconstruction with PMRT in the local patient cohort is oncologically safe, acceptable complication profile, revision rate, and aesthetic outcome. PRO showed lower scores in several categories, which differ from normative data generated in the Western population. Further studies will need to examine the confounding effects of radiation in this specific population.

Aesthetic outcomes of breast-conserving surgery and oncoplastic surgery with the new scale named Quality of Life Questionnaire Breast Reconstruction Module-23

Purpose

Oncoplastic surgery (OPS) has been developed with the aim of improving breast-conserving surgery (BCS) to provide better aesthetic and functional outcomes for breast cancer patients. We aimed to compare overall quality of life (QoL) and satisfaction with breast reconstruction in patients undergoing BCS and OPS using the Quality of Life Questionnaire Core 30 (QLQ-C30) and recently validated QLQ-Breast Reconstruction module (QLQ-BRECON23).

Methods

A total of 87 patients were included in this single-center study between January 1, 2018 and December 31, 2021; 43 underwent OPS (49.4%) and 44 underwent BCS (50.6%). The data on patient, tumor, and treatment characteristics were obtained from the prospectively collected database at the hospital. QLQ-C30 and QLQ-BRECON23 were used to evaluate psychosocial well-being, fatigue symptoms, overall QoL, sexual well-being, sensation of the operative area, and satisfaction with the reconstruction.

Results

According to QLQ-C30 evaluation there were significantly better outcomes for patients treated with OPS than BCS in terms of psychosocial well-being, fatigue symptoms, and overall QoL (P = 0.005, P = 0.016, and P = 0.004; respectively), according to QLQ-BRECON23 evaluation there were also significantly better outcomes in terms of sexual well-being, sensation of the operative area, and satisfaction of the reconstruction (P < 0.001, P = 0.002, and P < 0.001; respectively).

Conclusion

We found that the overall QoL and satisfaction with breast reconstruction in patients undergoing OPS are better than those undergoing BCS. Our study is critical because it is the first study comparing OPS and BCS using the QLQ-BRECON23, which was recently validated.

Modern Approaches to Oncoplastic Surgical Treatment

Partial breast reconstruction using oncoplastic techniques is performed at the time of lumpectomy and includes volume replacement techniques such as flaps and volume displacement techniques such as reduction and mastopexy. These techniques are used to preserve breast shape, contour, size, symmetry, inframammary fold position, and position of the nipple-areolar complex. Newer techniques such as auto-augmentation flaps and perforator flaps continue to broaden options and newer radiation therapy protocols will hopefully reduce side effects. Options for the oncoplastic approach now include higher risk patients as there is a larger repository of data on the safety and efficacy of this technique.

A Comparison of the Oncological Outcomes After Breast-Conserving Surgery With or Without Latissimus Dorsi Myocutaneous Flap Reconstruction for Breast Cancer

BACKGROUND

There is little information on the oncological outcomes of breast-conserving surgery (BCS) with immediate reconstruction using a latissimus dorsi myocutaneous flap (LDMF) for breast cancer compared with BCS alone.

PATIENTS AND METHODS

We conducted a retrospective cohort study from a single institution comparing the margin positivity rates after initial surgery, re-excision rates, and local recurrence (LR) between BCS with immediate LDMF reconstruction (n = 145) and BCS alone (n = 1040) performed from 2012 to 2017 for newly diagnosed stage 0-3 breast cancer.

RESULTS

The positive rates of surgical margin after initial surgery were significantly lower in the BCS with LDMF group than in the BCS alone group (4.1 vs. 10.8%; P = .006). There were no marked differences in the re-excision rates between the BCS with LDMF and BCS alone groups (P = .1). At a median follow-up of 61 months, the surgical method (BCS with LD vs. BCS alone) was not associated with the LR-free survival after adjusting for various clinicopathologic factors (P = .8).

CONCLUSION

Our findings suggest that BCS with immediate LDMF reconstruction is oncologically safe for breast cancer compared with BCS alone. However, further studies are needed.

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.

Development of an online research platform for use in a large-scale multicentre study

Background

Participation in research can be beneficial for patients and healthcare providers, but may prove demanding at patient, clinician and organizational levels. Patient representatives are supportive of online research to overcome these challenges. The aim of this pilot study was to develop an online recruitment platform and test its feasibility and acceptability while evaluating the accuracy of participant-reported data.

Methods

The online research platform was developed in a 1-day ‘hackathon’ with a digital design company. Women who underwent implant-based breast reconstruction in 2011–2016 were invited by letter containing the web address (URL) of the study site and their unique study number. Once online, participants learned about the study, consented, entered data on demographics, treatment received and patient-reported outcome measures (BREAST-Q™), and booked an appointment for a single hospital visit for three-dimensional surface imaging (3D-SI). Real-time process evaluation was performed. The primary endpoint was recruitment rate.

Results

The recruitment rate was 40 per cent. Of the 100 women, 50 logged on to the platform and 40 completed the process through to 3D-SI. The majority of discontinuations after logging on occurred between consenting and entering demographics (3 women, 6 per cent), and between completing the BREAST-Q and booking an appointment for 3D-SI using the online calendar (3 women, 6 per cent). All women completed the online BREAST-Q™ once started. Participants took a median of 23 minutes to complete the online process. Patient-reported clinical data were accurate in 12 of 13 domains compared with electronic records (95 per cent concordance). Process evaluation demonstrated acceptability.

Conclusion

The results of this pilot demonstrate the online platform to be acceptable, feasible, and accurate for this population from a single institution. The low-burden design may enable participation from centres with less research support and participants from hard-to-reach groups or dispersed geographical locations, but with online access.

3-Dimensional objective aesthetic evaluation to replace panel assessment after breast-conserving treatment

BACKGROUND

Two-thirds of patients with early breast cancer undergo breast-conserving treatment (BCT). Aesthetic outcome is important and has long term implications for psychosocial wellbeing. The aesthetic goal of BCT is symmetry for which there is no gold-standard measure. Panel scoring is the most widely adopted assessment but has well-described limitations. This paper describes a model to objectively report aesthetic outcome using measures derived from 3-dimensional surface images (3D-SI).

METHOD

Objective measures and panel assessment were undertaken independently for 3D-SI of women who underwent BCT 1-5 years previously. Univariate analysis was used to test for association between measures and panel score. A forward stepwise multiple linear regression model was fitted to identify 3D measurements that jointly predicted the mean panel score. The fitted model coefficients were used to predict mean panel scores for an independent validation set then compared to the mean observed panel score.

RESULTS

Very good intra-panel reliability was observed for the training and validation sets (wκ = 0.87, wκ = 0.84). Six 3D-measures were used in the multivariate model. There was a good correlation between the predicted and mean observed panel score in the training (n = 190) and validation (n = 100) sets (r = 0.68, r = 0.65). The 3D model tended to predict scores towards the median. The model was calibrated which improved the distribution of predicted scores.

CONCLUSION

A six-variable objective aesthetic outcome model for BCT has been described and validated. This can predict and could replace panel assessment, facilitating the independent and unbiased evaluation of aesthetic outcome to communicate and compare results, benchmark practice, and raise standards.

A scoring system for 3D surface images of breast reconstruction developed using the Delphi consensus process

Introduction

Evaluation of aesthetics after breast reconstruction is challenging. In the absence of an objective measurement, panel assessment is widely adopted. Heterogeneity of scales and poor internal consistency make comparison difficult. Development and validation of an expert panel scale using a Delphi consensus process is described. It was designed specifically for use as the gold standard for development of an objective evaluation tool using 3-Dimensional Surface Imaging (3D-SI).

Materials and methods

20 items relating to aesthetic assessment were identified for consideration in the Delphi consensus process. Items were selected for inclusion in the definitive panel scale by iterative rounds of voting according to importance, consensus discussion, and a final vote. The Delphi-derived scale was tested on a clinical research series for intra- and inter-panellist, and intra-panel reliability, and correlation with Patient Reported Outcome Measures (PROMs).

Results

61 surgeons participated in the Delphi process. Oncoplastic and plastic surgeons were represented. The Delphi-derived scale included symmetry, volume, shape, position of breast mound, nipple position, and a global score. Intra-panellist reliability ranged from poor to almost perfect (wκ<0to0.86), inter-rater reliability was fair (ICC range 0.4–0.5) for individual items and good (ICC0.6) for the global score, intra-panel reliability was moderate to substantial (wκ0.4–0.7), and correlation with PROMs was moderate (r = 0.5p < 0.01).

Conclusions

The Delphi-derived panel evaluation is at least as good as other scales in the literature and has been developed specifically to provide expert evaluation of aesthetics after breast reconstruction. The logistical constraints of panel assessment remain, reinforcing the need to develop an objective evaluation method.

•

Aesthetic outcome has well described influence on long term quality of life

•

Many scoring systems exist, each with methodological flaws.

•

A Delphi consensus process was used to derive a contemporary panel scoring system for expert aesthetic evaluation

•

The scoring system was tested and performed well on a series of images of women who have undergone breast reconstruction

Satisfaction with the Aesthetic Effect and Quality of Life for Women after Breast Conserving Therapy (BCT)-Preliminary Research

All methods of breast cancer treatment may potentially lead to breast deformities, which are often associated with the reduced mental well-being of patients. Breast conserving therapy (BCT) is commonly used, and its core element is breast conserving surgery (BCS).The aim of this study was to determine the level of satisfaction with the aesthetic outcome of surgery and quality of life (QoL) of breast cancer patients undergoing BCT in a longitudinal study performed three months, six months and 12 months after surgery. This longitudinal observational study was carried out on a group of 91 women. The Breast-Q^TM BCT 1.0 questionnaire was used in this study. Before surgery, patients assessed their satisfaction with the appearance of their breasts (SwB) at an average level of M = 56.0. Satisfaction with the aesthetic outcome (SwO) of BCS was highest among all patients three months after surgery (M = 63.0). The mean score in the sub-scale of psychosocial well-being (Psycho-soc W-B) before surgery was M = 62.0, while in the subsequent periods of the study, it was higher. The mean score for physical well-being (Physical W-B) before surgery was M = 69.92; and in the subsequent study periods, it was lower. The level of patient satisfaction with the outcome of the surgery and the QoL related to health do not differ significantly in post-operative observation. QoL in terms of psychosocial functioning in patients undergoing BCT is significantly higher 12 months after surgery compared to the pre-operative period. Patient satisfaction with the BCS aesthetic outcome is positively related to the evaluation of QoL in terms of psychosocial functioning.

Oncoplastic Volume Replacement for Breast Cancer: Latissimus Dorsi Flap versus Thoracodorsal Artery Perforator Flap

Volume replacement oncoplastic breast techniques have become one of the standard lines in the treatment of early breast cancer. They have better cosmetic outcome and patient satisfaction. Latissimus dorsi (LD) flap is one of the most commonly used flaps for these techniques. Although it shows satisfactory surgical outcomes, postoperative shoulder dysfunction is an obvious drawback. The aim of this study was to compare LD flap with thoracodorsal artery perforator (TDAP) flap after breast-conserving surgery regarding surgical outcomes, patient satisfaction, and impact on shoulder function.

Postoperative Cancer Surveillance Following Oncoplastic Surgery with Latissimus Dorsi Flap: a Matched Case-Control Study

BACKGROUND

The latissimus dorsi (LD) myocutaneous flap is a widely used local option in oncoplastic surgery for avoiding breast deformities; however, concerns exist regarding its influence in monitoring recurrence. In this study, we evaluated the impact of this flap on postoperative cancer surveillance.

METHODS

Each patient receiving oncoplastic surgery with LD flap after partial mastectomy were matched in age, cancer stage, and body mass index with patients receiving partial mastectomy alone. Twenty-nine patients with the oncoplastic LD flap received 99 mammograms and 139 ultrasonograms, while 29 patients with partial mastectomy alone underwent 92 mammograms and 129 ultrasonograms. Mammographic and ultrasonographic findings were classified by Breast Imaging Reporting and Data System (BI-RADS) category and reviewed. Any recommendations for additional evaluation and recurrence were documented.

RESULTS

During an average follow-up period of 44 months, although the oncoplastic group demonstrated more newly developed benign calcifications (control 14% vs. oncoplastic 41%; p = 0.019) on mammography, the percentage of recall for additional imaging in category 0, and the short-interval follow-up in category 3, was not different between the control and oncoplastic group. Regarding ultrasonography, BI-RADS category was also not different between the two groups; however, the control group showed more fluid collections than the oncoplastic group (control 21% vs. oncoplastic 0%; p = 0.023). One case of local recurrence was observed in the control group.

CONCLUSION

Although there was an increase in benign calcifications in the oncoplastic group, there were no additional abnormal findings requiring further intervention. We concluded that the LD flap for oncoplastic surgery does not interfere with cancer surveillance, and even decreases the rate of fluid collection.

Oncoplastic Breast Reconstruction: Should All Patients be Considered?

Oncoplastic surgery of the tissue defect from partial mastectomy should be considered for all patients. It can result in in significant asymmetries from scar contraction, skin tethering, and alterations in the nipple areolar complex location. Indications, risks, and benefits are discussed. Optimal procedures are described, considering resected specimen volume, primary tumor location, tumor to breast size ratio, and the impact on the nipple areolar complex. Indications for plastic surgery consultation and joint surgery are discussed. Surgical management includes incision planning, preservation of the nipple areolar complex pedicle and position, patient positioning, incision location, and recovery.

The value of 3D images in the aesthetic evaluation of breast cancer conservative treatment. Results from a prospective multicentric clinical trial

PURPOSE

BCCT.core (Breast Cancer Conservative Treatment. cosmetic results) is a software created for the objective evaluation of aesthetic result of breast cancer conservative treatment using a single patient frontal photography. The lack of volume information has been one criticism, as the use of 3D information might improve accuracy in aesthetic evaluation. In this study, we have evaluated the added value of 3D information to two methods of aesthetic evaluation: a panel of experts; and an augmented version of the computational model - BCCT.core3d.

MATERIAL AND METHODS

Within the scope of EU Seventh Framework Programme Project PICTURE, 2D and 3D images from 106 patients from three clinical centres were evaluated by a panel of 17 experts and the BCCT.core. Agreement between all methods was calculated using the kappa (K) and weighted kappa (wK) statistics.

RESULTS

Subjective agreement between 2D and 3D individual evaluation was fair to moderate. The agreement between the expert classification and the BCCT.core software with both 2D and 3D features was also fair to moderate.

CONCLUSIONS

The inclusion of 3D images did not add significant information to the aesthetic evaluation either by the panel or the software. Evaluation of aesthetic outcome can be performed using of the BCCT.core software, with a single frontal image.

Aesthetic result after breast-conserving therapy is associated with quality of life several years after treatment. Swedish women evaluated with BCCT.core and BREAST-Q™

Purpose

A gold standard for evaluation of aesthetic outcome after breast-conserving therapy (BCT) is still lacking. The BCCT.core software has been developed to assess aesthetic result in a standardised way. We aimed to study how the result of BCCT.core after BCT is associated with quality of life, measured with the BREAST-Q™, a validated questionnaire.

Methods

Women eligible for BCT were consecutively recruited between February 1st 2008 and January 31st 2012 (n = 653). Photographs of 310 women, taken one year after BCT, were evaluated using the BCCT.core software. The postoperative BCT module of the BREAST-Q™ questionnaire was administered by mail and 348 questionnaires were returned (median 5.5 years after BCT). In all, 216 women had both BCCT.core results and completed BREAST-Q™ questionnaires available.

Results

The results from the BCCT.core evaluation were: excellent n = 49 (15.8%); good n = 178 (57.4%); fair n = 73 (23.5%); poor n = 10 (3.2%). The median BREAST-Q™ score for satisfaction with breasts was 66 [interquartile range (IQR) 57–80] and for psychosocial well-being 82 (IQR 61–100). Poor/fair results on BCCT.core were associated with Q-scores below median for both satisfaction with breasts [odds ratio (OR) 3.4 (confidence interval (CI) 1.7–6.8)] as well as for psychosocial well-being [OR 2.2 (CI 1.1–4.2)].

Conclusions

A statistically significant association between BCCT.core results one year after BCT and quality of life ratings using BREAST-Q™ several years later is shown in this study. This implies that the BCCT.core may be valuable in BCT follow-up and used as a standardised instrument in the evaluation of aesthetic results.
