RESUMO
BACKGROUND: With evolving breast cancer survival and patient preferences, it is essential that reconstructive surgeons worldwide continue searching for the best reconstruction technique for patients. Autologous fat transfer (AFT) is a relatively new technique for total breast reconstruction that has already proven to be effective and safe with all advantages of autologous tissue. However, little is known about the aesthetic results and satisfaction concerning donor sites. OBJECTIVES: The aim of this study was to measure donor site satisfaction following AFT for total breast reconstruction in breast cancer patients. METHODS: Between May and August of 2021, participants of the BREAST- trial who were at least 24 months after their final reconstruction surgery were invited to complete an additional survey concerning donor sites. The BODY-Q was utilized for data collection. Results of AFT patients were compared with a control group of implant-based reconstruction patients who did not have a donor site. RESULTS: A total of 51 patients (20 control, 31 intervention) completed the questionnaire. Satisfaction with body did not statistically differ between the groups. The most frequent complaint was contour irregularities (31 reports, 60.8%), with the least favorable donor site being thighs (23 reports, 53.5%) in the AFT group. CONCLUSIONS: Satisfaction with body did not differ between breast cancer patients receiving AFT or implant-based reconstruction, meaning that large-volume liposuction does not aesthetically affect the utilized donor sites. Nevertheless, reconstructive surgeons should be aware of possible donor site complications, especially contour irregularities at the thighs, and discuss this with their patients.

How are tactile sensations in the breast represented in the female and male brain? Using ultra high-field 7â¯T MRI in ten females and ten males, we demonstrate that the representation of tactile breast information shows a somatotopic organization, with cortical magnification of the nipple. Furthermore, we show that the core representation of the breast is organized according to the specific nerve architecture that underlies breast sensation, where the medial and lateral sides of one breast are asymmetrically represented in bilateral primary somatosensory cortex. Finally, gradual selectivity signatures allude to a somatotopic organization of the breast area with overlapping, but distinctive, cortical representations of breast segments. Our univariate and multivariate analyses consistently showed similar somatosensory breast representations in males and females. The findings can guide future research on neuroplastic reorganization of the breast area, across reproductive life stages, and after breast surgery.

BACKGROUND: This study aimed to develop an easy to use prediction model to predict the risk of having a total of 1 to 2, ≥3, or ≥4 positive axillary lymph nodes (LNs), for patients with sentinel lymph node (SLN) positive breast cancer. METHODS: Data of 911 SLN positive breast cancer patients were used for model development. The model was validated externally in an independent population of 180 patients with SLN positive breast cancer. RESULTS: Final pathology after ALND showed additional positive LN for 259 (28%) of the patients. A total of 726 (81%) out of 911 patients had a total of 1 to 2 positive nodes, whereas 175 (19%) had ≥3 positive LNs. The model included three predictors: the tumor size (in mm), the presence of a negative SLN, and the size of the SLN metastases (in mm). At external validation, the model showed a good discriminative ability (area under the curve = 0.82; 95% confidence interval = 0.74-0.90) and good calibration over the full range of predicted probabilities. CONCLUSION: This new and validated model predicts the extent of nodal involvement in node-positive breast cancer and will be useful for counseling patients regarding their personalized axillary treatment.

PURPOSE: The number of breast cancer survivors continues to grow. Due to refinements in operating techniques, autologous breast reconstruction has become part of standard care. Impaired sensation remains a debilitating side effect with a significant impact on the quality of life. Microsurgical nerve coaptation of a sensory nerve has the potential to improve sensation of the reconstructed breast. This study investigates the effect of improved sensation of the reconstructed breast on the quality of life in breast cancer survivors. METHODS: A retrospective cohort study was performed in the Maastricht University Medical Center. Patients undergoing a DIEP flap breast reconstruction between January 2015 and January 2016 were included. The primary outcome was quality of life (BREAST-Q domain 'physical well-being of the chest'). The Semmes-Weinstein monofilaments were used for objective sensation measurement of the reconstructed breast(s). RESULTS: Eighteen patients with and 14 patients without nerve coaptation responded. Nipple reconstruction was the only characteristic that differed statistically significant between both groups (p = 0.04). The BREAST-Q score for the domain physical well-being of the chest was 77.89 ± 18.89 on average in patients with nerve coaptation and 66.21 ± 18.26 in patients without nerve coaptation (p = 0.09). Linear regression showed a statistically significant relation between objectively measured sensation and BREAST-Q score for the domain physical well-being of the chest with a regression coefficient of - 13.17 ± 3.61 (p < 0.01). CONCLUSIONS: Improved sensation in the autologous reconstructed breast, with the addition of microsurgical nerve coaptation, has a statistical significant positive impact on the quality of life in breast cancer survivors according to the BREAST-Q.

BACKGROUND: Restoring the body as normal as possible increases quality of life. Aesthetically, almost perfect breast reconstructions can be created. However, these reconstructed breasts have almost no sensation. Our hypothesis is that if we succeed in restoring sensation, this will increase quality of life. So far, little is written about the phenomenon of breast sensation, which makes it difficult to evaluate whether the quality of life increases after restored sensation. Therefore, the primary goal of this study is to determine what the importance and meaning is of breast sensation among healthy women. METHODS: A qualitative, descriptive phenomenological study was performed in an academic hospital between October 2016 and March 2017. A total of 10 semi-structured in-depth interviews were conducted in healthy women who did not undergo prior breast surgery. The sample size was based upon 'saturation'. The interviews were tape-recorded, transcribed verbatim, coded and analysed according to phenomenology keeping in mind the research question 'what is the importance and meaning of sensation of the breast?' RESULTS: Seven interrelated themes on how sensation of the breast is experienced were found: the absent breast (1), the present breast (2), the well-functioning breast (2a), the feminine breast (2b), the sensual breast (2c), the alien breast (2d), the safe breast (2d). CONCLUSIONS: The seven interrelated themes can form the basis to develop a quantitative research tool to evaluate quality of life after innervated breast reconstruction and can be implemented in counselling before breast reconstructive surgery in the form of shared treatment decisions.

INTRODUCTION: It is known that breast reconstruction improves quality of life (QoL) in women who underwent mastectomy. Previous studies showed that autologous immediate breast reconstruction is as safe as delayed breast reconstruction. However, there is not much known about the influence of the timing of the breast reconstruction on QoL. Therefore, this study aims to assess the effect of timing of the breast reconstruction on QoL, using the BREAST-Q questionnaire. METHODS: A total of 543 patients aged 18 years or older who underwent deep inferior epigastric perforator flap reconstruction after mastectomy (for prophylactic or oncological reasons) at least 12 months ago were selected in 3 hospitals in the Netherlands and invited to complete the BREAST-Q. Mean QoL outcomes were compared between patients who underwent immediate or delayed breast reconstruction. Furthermore, QoL outcomes were compared with recently published normative data of the BREAST-Q. RESULTS: Patients who underwent immediate reconstruction reported higher scores on satisfaction with psychosocial well-being, sexual well-being, physical well-being of the chest, and physical well-being of the abdomen. Patients who underwent delayed reconstruction reported higher scores on satisfaction with breasts, outcome, and nipples. However, after adjusting for potentially influencing factors, none of the differences were significant. Compared with the normative BREAST-Q data, both of our patient groups reported higher scores on satisfaction with breasts, psychological well-being, and sexual well-being, whereas they reported lower scores on satisfaction with physical well-being of the chest and the abdomen. CONCLUSIONS: This study suggests that patients who underwent immediate or delayed deep inferior epigastric perforator flap breast reconstruction have comparable QoL more than 1 year after surgery, irrespective of the timing of the breast reconstruction.

BACKGROUND: Pathological complete response (pCR) is the ultimate response in breast cancer patients treated with neoadjuvant chemotherapy (NCT). It might be a surrogate outcome for disease-free survival (DFS) and overall survival (OS). We studied the effect of clinical tumor stage (cT-stage) on tumor pCR and the effect of pCR per cT-stage on 5-year OS and DFS. METHODS: Using the Netherlands Cancer Registry, all primary invasive breast cancer patients treated with NCT from 2005 until 2008 were identified. Univariable logistic regression analysis was performed to evaluate the effect of cT-stage on pCR, stepwise logistic regression analysis to correct for potential confounders and Kaplan-Meier survival analyses to calculate OS and DFS after five years. RESULTS: In 2366 patients, overall pCR rate was 21%. For cT1, cT2, cT3, and cT4, pCR rates were 31, 22, 18, and 17%, respectively. Lower cT-stage (cT1-2 vs cT3-4) was a significant independent predictor of higher pCR rate (p < 0.001, OR 3.15). Furthermore, positive HER2 status (p < 0.001, OR 2.30), negative estrogen receptor status (p = 0.062, OR 1.69), and negative progesterone receptor status (p = 0.008, OR 2.27) were independent predictors of pCR. OS and DFS were up to 20% higher in patients with cT2-4 tumors with pCR versus patients without pCR. DFS was also higher for cT1 tumors with pCR. CONCLUSIONS: The most important predictor of pCR in breast cancer patients is cT-stage: lower cT-stages have significantly higher pCR rates than higher cT-stages. Patients with cT2-4 tumors achieving pCR have higher OS and DFS compared to patients not achieving pCR.

Background To evaluate the quality of life (QOL) of breast cancer survivors who have undergone breast reconstruction and have breast cancer-related lymphedema (BCRL). Methods Patients with a unilateral mastectomy with or without breast reconstruction were evaluated for BCRL and their QOL. Patients were divided into a non-BCRL and a BCRL group. Patients with subjective complaints of arm swelling and/or an interlimb volume difference of >200 mL, or undergoing treatment for arm lymphedema were defined as having BCRL. QOL was assessed using cancer-specific (EORTC QLQ-C30 and EORTC QLQ-B23) and disease specific (Lymph-ICF) questionnaires. Results In total, 253 patients with a mean follow-up time of 51.7 (standard deviation = 18.5) months since mastectomy completed the QOL questionnaires. Of these patients, 116 (46%) underwent mastectomy alone and 137 (54%) had additional breast reconstruction. A comparison of the QOL scores of 180 patients in the non-BCRL group showed a significantly better physical function (p = 0.004) for patients with reconstructive surgery compared with mastectomy patients. In the 73 patients with BCRL, a comparison of the QOL scores showed no significant differences between patients with mastectomy and reconstructive surgery. After adjusting for potential confounders, multivariate analysis showed a significant impact of BCRL on physical function (ß = - 7.46; p = 0.009), role function (ß = - 15.75; p = 0.003), cognitive function (ß = - 11.56; p = 0.005), body vision (ß = - 11.62; p = 0.007), arm symptoms (ß = 20.78; p = 0.000), and all domains of the Lymph-ICF questionnaire. Conclusions This study implies that BCRL has a negative effect on the QOL of breast cancer survivors, potentially negating the positive effects on QOL reconstructive breast surgery has.

PURPOSE: To evaluate the diagnostic performance of unenhanced axillary T2-weighted and diffusion-weighted (DW) magnetic resonance (MR) imaging for axillary nodal staging in patients with newly diagnosed breast cancer, with node-by-node and patient-by-patient validation. MATERIALS AND METHODS: Institutional review board approval and informed consent were obtained. Fifty women (mean age, 60 years; range, 22-80 years) underwent high-spatial-resolution axillary 3.0-T T2-weighted imaging without fat suppression and DW imaging (b = 0, 500, and 800 sec/mm(2)), followed by either sentinel lymph node biopsy (SLNB) or axillary lymph node dissection. Two radiologists independently scored each lymph node on a confidence level scale from 0 (benign) to 4 (malignant), first on T2-weighted MR images, then on DW MR images. Two researchers independently measured the mean apparent diffusion coefficient (ADC) of each lymph node. Diagnostic performance parameters were calculated on the basis of node-by-node and patient-by-patient validation. RESULTS: With respective node-by-node and patient-by-patient validation, T2-weighted MR imaging had a specificity of 93%-97% and 87%-95%, sensitivity of 32%-55% and 50%-67%, negative predictive value (NPV) of 88%-91% and 86%-89%, positive predictive value (PPV) of 60%-70% and 62%-75%, and area under the receiver operating characteristic curve (AUC) of 0.78 and 0.80-0.88, with good interobserver agreement (κ = 0.70). The addition of DW MR imaging resulted in lower specificity (59%-88% and 50%-84%), higher sensitivity (45%-64% and 75%-83%), comparable NPV (89% and 90%-91%), lower PPV (23%-42% and 34%-60%), and lower AUC (0.68-0.73 and 0.70-0.86). ADC measurement resulted in a specificity of 63%-64% and 61%-63%, sensitivity of 41% and 67%, NPV of 85% and 85%-86%, PPV of 18% and 35%-36%, and AUC of 0.54-0.58 and 0.69-0.74, respectively, with excellent interobserver agreement (intraclass correlation coefficient, 0.83). CONCLUSION: Dedicated high-spatial-resolution axillary T2-weighted MR imaging showed good specificity on the basis of node-by-node and patient-by-patient validation, with good interobserver agreement. However, its NPV is still insufficient to substitute it for SLNB for exclusion of axillary lymph node metastasis. DW MR imaging and ADC measurement were of no added value.

Autologous fat transfer (AFT) is an upcoming technique for total breast reconstruction. Consequently, radiological imaging of women with an AFT reconstructed breast will increase in the coming years, yet radiological experience and evidence after AFT is limited.The surgical procedure of AFT and follow-up with imaging modalities including mammography (MG), ultrasound (US), and MRI in patients with a total breast reconstruction with AFT are summarized to illustrate the radiological normal and suspicious findings for malignancy.Imaging after a total breast reconstruction with AFT appears to be based mostly on benign imaging findings with an overall low biopsy rate. As higher volumes are injected in this technique, the risk for the onset of fat necrosis increases. Imaging findings most often are related to fat necrosis after AFT. On MG, fat necrosis can mostly be seen as oil cysts. The occurrence of a breast seroma after total breast reconstruction with AFT is an unfavourable outcome and may require special treatment. Fat deposition in the pectoral muscle is a previously unknown, but benign entity. Although fat necrosis is a benign entity, it can mimic breast cancer (recurrence).In symptomatic women after total breast reconstruction with AFT, MG and US can be considered as first diagnostic modalities. Breast MRI can be used as a problem-solving tool during later stage. Future studies should investigate the most optimal follow-up strategy, including different imaging modalities, in patients treated with AFT for total breast reconstruction.
RESUMO
BACKGROUND: With developments in screening and treatment, survival rates of breast cancer patients are increasing, and so is the number of women opting for breast reconstruction to improve their quality of life. One factor that could play an important role in improving the quality of life is breast sensibility. Therefore, the aim of this study was to explore breast sensibility in participants of the Breast Reconstruction with External Preexpansion and Autologous Fat Transfer versus Standard Therapy trial: an ongoing randomized controlled trial comparing breast reconstruction with autologous fat transfer (AFT) versus implant-based reconstruction (IBR). METHODS: This study was conducted on participants of the Breast Reconstruction with External Preexpansion and Autologous Fat Transfer versus Standard Therapy trial who were at least 12 months after final surgery. Semmes-Weinstein monofilaments were used to measure skin sensibility in breast cancer patients who underwent breast reconstruction with either AFT or IBR following their mastectomy. RESULTS: A total of 46 patients were included in this study, resulting in 62 breast reconstructions (28 AFT breasts and 34 IBR breasts). Significantly higher mean monofilament values were found for skin sensibility after AFT (-0.7; P < 0.001), clinically correlating to "diminished protective function," as opposed to the IBR group, with clinical values indicating "loss of protective function." CONCLUSIONS: In this study, the authors found that breast cancer patients who underwent a mastectomy had a significantly better sensibility of the breast following AFT for total breast reconstruction as compared with IBR. Larger studies that include null measurements are required to further explore these noteworthy results of AFT. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

BACKGROUND: Upper limb lymphedema is one of the most underestimated and debilitating complications of breast cancer treatment. The aim of this review is to summarize the recent literature for evidence of the effectiveness of lymphatic microsurgery for the treatment of breast cancer-related lymphedema (BCRL). METHODS: A search was conducted for articles published from January 2000 until January 2012. Only studies on secondary lymphedema after breast cancer treatment and those examining the effectiveness of microsurgery were included. RESULTS: No randomized clinical trials or comparative studies were available. Ten case-series met inclusion criteria: (composite) tissue transfer (n = 4), lymphatic vessel transfer (n = 2), and derivative microlymphatic surgery (n = 4). Limb volume/circumference reduction varied from 2 to 50% over a follow-up time ranging from 1 to 132 months. Postoperative discontinuation rates of conservative therapy were only reported after composite tissue transfer, ranging from 33 to 100% after 3 to 24 months. Clear selection criteria for lymphatic surgery and lymphatic flow assessment were absent in most studies. CONCLUSION: We identified important methodological shortcomings of the available literature. Evidence acquired through comparative studies with uniform patient selection is lacking. Consistent positive findings with regards to limb volume reduction and limited complications are reasons to further explore these techniques in methodologically superior studies.

BACKGROUND: Autologous breast reconstruction has become standard of care, but there is no consensus on prophylactic antibiotic regimens for this surgical procedure. This review aims to present evidence on the best prophylactic antibiotic protocol to lower the risk of surgical site infections in autologous breast reconstructions. METHODS: The search was performed in PubMed, EMBASE, Web of Science, and Cochrane Library on 25th of January 2022. Data on the number of surgical site infections, breast reconstruction type (pedicled or free flap) and reconstruction timing (immediate or delayed), as well as data on the type, dose, route of administration, timing, and duration of antibiotic treatment were extracted. All included articles were additionally assessed for potential risk of bias by using the revised RTI Item Bank tool. RESULTS: 12 studies were included in this review. No evidence is found that giving post-operative antibiotics for a prolonged period longer than 24 h after surgery is useful in lowering infection rates. This review could not distinguish between the best choice of antimicrobial agent. DISCUSSION: Although this is the first study that collected current evidence on this topic, the quality of evidence is limited due to a small number of available studies (N = 12) with small study populations. The included studies have high heterogeneity, no adjustment for confounding, and interchangeably used definitions. Future research is highly recommended with predefined definitions, and a sufficient number of included patients. CONCLUSION: Antibiotic prophylaxis up to a maximum of 24 h is useful in lowering infection rates in autologous breast reconstructions.

BACKGROUND: Implant-based breast reconstructions contribute considerably to the quality of life of breast cancer patients. A knowledge gap exists concerning the potential role of silicone breast implants in the development of so-called "breast implant illness" (BII) and autoimmune diseases in breast cancer survivors with implant-based reconstructions. BII is a constellation of non-specific symptoms reported by a small group of women with silicone breast implants. METHODS: The Areola study is a multicenter retrospective cohort study with prospective follow-up aiming to assess the risk of BII and autoimmune diseases in female breast cancer survivors with and without silicone breast implants. In this report, we set out the rationale, study design, and methodology of this cohort study. The cohort consists of breast cancer survivors who received surgical treatment with implant-based reconstruction in six major hospitals across the Netherlands in the period between 2000 and 2015. As a comparison group, a frequency-matched sample of breast cancer survivors without breast implants will be selected. An additional group of women who received breast augmentation surgery in the same years will be selected to compare their characteristics and health outcomes with those of breast cancer patients with implants. All women who are still alive will be invited to complete a web-based questionnaire covering health-related topics. The entire cohort including deceased women will be linked to population-based databases of Statistics Netherlands. These include a registry of hospital diagnostic codes, a medicines prescription registry, and a cause-of-death registry, through which diagnoses of autoimmune diseases will be identified. Outcomes of interest are the prevalence and incidence of BII and autoimmune diseases. In addition, risk factors for the development of BII and autoimmune disorders will be assessed among women with implants. DISCUSSION: The Areola study will contribute to the availability of reliable information on the risks of BII and autoimmune diseases in Dutch breast cancer survivors with silicone breast implants. This will inform breast cancer survivors and aid future breast cancer patients and their treating physicians to make informed decisions about reconstructive strategies after mastectomy. REGISTRATION: This study is registered at ClinicalTrials.gov on June 2, 2022 (NCT05400954).

BACKGROUND: Breast cancer is the most common cancer in females worldwide. One option for total breast reconstruction following total breast amputation is autologous fat transfer (AFT). However, this is still an upcoming reconstruction technique, and little is known about the donor site complications and their influence on the patient's overall satisfaction. OBJECTIVES: This systematic review aims to review the current literature regarding donor site complications and donor site satisfaction following AFT for total breast reconstruction. SEARCH METHODS: A literature search was performed in PubMed, Web of Science, Embase, Cochrane, TRIP pro, and Prospero. All published original literature reporting on complications or satisfaction at the donor site in patients who underwent liposuction, followed by high-volume lipofilling was considered. MAIN RESULTS: This systematic review resulted in the inclusion of 21 cohort studies, consisting of 2241 participants. None of the studies reported donor site satisfaction scores of any kind. The most frequently reported donor site complication was ecchymosis (268 cases), followed by pain (122 cases), haematoma (58 cases), irregularities (12 cases), burns (four cases), and infection (three cases). Reports on follow-up and management of donor site complications were generally lacking. AUTHOR'S CONCLUSIONS: Results regarding the donor site are inconclusive. Pre-specified complications, a standardized manner of reporting, long-term follow-up, and patient-reported outcome measures are lacking in most of the studies. The impact of the donor site on quality of life after autologous fat grafting in breast reconstruction remains a blind spot. PROSPERO registration number: CRD42020222870.

BACKGROUND: Restoring the sensation of the reconstructed breast has increasingly become a goal of autologous breast reconstruction. The aim of this study was to analyze the sensory recovery of the breast and donor site of innervated compared to noninnervated deep inferior epigastric perforator (DIEP) flap breast reconstructions, to assess associated factors, and to compare the differences between preoperative and postoperative sensation. METHODS: A prospective cohort study was conducted, including patients who underwent innervated or noninnervated DIEP flap breast reconstruction between August of 2016 and August of 2018. Nerve coaptation was performed to the anterior cutaneous branch of the third intercostal nerve. Preoperative and postoperative sensory testing of the breast and donor site was performed with Semmes-Weinstein monofilaments. RESULTS: A total of 67 patients with 94 innervated DIEP flaps and 58 patients with 80 noninnervated DIEP flaps were included. Nerve coaptation was significantly associated with lower mean monofilament values for the breast (-0.48; p < 0.001), whereas no significant differences were found for the donor site (-0.16; p = 0.161) of innervated compared to noninnervated DIEP flaps. Factors positively or negatively associated with sensory recovery of the breast and donor site were identified. Preoperative versus postoperative comparison demonstrated significantly superior sensory recovery of the breast in innervated flaps (adjusted difference, -0.48; p = 0.017). CONCLUSIONS: This study demonstrated that nerve coaptation in DIEP flap breast reconstruction significantly improved the sensory recovery of the breast compared to noninnervated flaps. The sensory recovery of the donor site was not compromised in innervated reconstructions. The results support the role of nerve coaptation in autologous breast reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

INTRODUCTION: The better survival rates after breast cancer allow for setting of long-term goals, such as Quality of Life (QoL) and aesthetic outcomes following breast reconstruction. Studies find a higher breast-related QoL and greater satisfaction with breasts following autologous breast reconstruction (ABR) compared to implant-based breast reconstruction (IBR). However, aesthetic results from donor sites can influence body image. This concern is little addressed in the literature. Therefore, the aim of this study was to compare the long-term breast-related and body-related QoL of women who underwent ABR to women who underwent IBR. MATERIAL AND METHODS: A multicenter, cross-sectional survey was conducted between November and December 2020 among women who underwent postmastectomy breast reconstruction between January 2015 and December 2018. A general questionnaire, the BREAST-Q, and the BODY-Q were used to collect data. Multivariable linear regression was performed to adjust differences in Q-scores for potential confounders. RESULTS: In total, 336 patients were included (112 IBR, 224 ABR). Autologous reconstruction resulted in significantly higher mean scores in all subdomains of the BREAST-Q. On the BODY-Q, IBR scored significantly higher on scars, while ABR scored moderately to significantly higher on all other scales. Despite a lower mean score on Hips & outer thighs in women with Lateral Thigh Perforator (LTP) flap reconstruction, no negative influence on body image was found in these women. CONCLUSIONS: Long-term breast-related and body-related outcomes of ABR are superior to IBR. Donor site aesthetic does not adversely affect body image in women who underwent free flap breast reconstruction.

This retrospective study investigated the value of pretreatment contrast-enhanced Magnetic Resonance Imaging (MRI)-based radiomics for the prediction of pathologic complete tumor response to neoadjuvant systemic therapy in breast cancer patients. A total of 292 breast cancer patients, with 320 tumors, who were treated with neo-adjuvant systemic therapy and underwent a pretreatment MRI exam were enrolled. As the data were collected in two different hospitals with five different MRI scanners and varying acquisition protocols, three different strategies to split training and validation datasets were used. Radiomics, clinical, and combined models were developed using random forest classifiers in each strategy. The analysis of radiomics features had no added value in predicting pathologic complete tumor response to neoadjuvant systemic therapy in breast cancer patients compared with the clinical models, nor did the combined models perform significantly better than the clinical models. Further, the radiomics features selected for the models and their performance differed with and within the different strategies. Due to previous and current work, we tentatively attribute the lack of improvement in clinical models following the addition of radiomics to the effects of variations in acquisition and reconstruction parameters. The lack of reproducibility data (i.e., test-retest or similar) meant that this effect could not be analyzed. These results indicate the need for reproducibility studies to preselect reproducible features in order to properly assess the potential of radiomics.
RESUMO
BACKGROUND: The sensory recovery of the breast remains an undervalued aspect of autologous breast reconstruction. The aim of this study was to evaluate the effect of nerve coaptation on the sensory recovery of the breast following DIEP flap breast reconstruction and to assess the associations of length of follow-up and timing of the reconstruction. METHODS: A prospective comparative study was conducted of all patients who underwent either innervated or noninnervated DIEP flap breast reconstruction and returned for follow-up between September of 2015 and July of 2017. Nerve coaptation was performed to the anterior cutaneous branch of the third intercostal nerve. Semmes-Weinstein monofilaments were used for sensory testing of the native skin and flap skin. RESULTS: A total of 48 innervated DIEP flaps in 36 patients and 61 noninnervated DIEP flaps in 45 patients were tested at different follow-up time points. Nerve coaptation was significantly associated with lower monofilament values in all areas of the reconstructed breast (adjusted difference, -1.2; p < 0.001), which indicated that sensory recovery of the breast was significantly better in innervated compared with noninnervated DIEP flaps. For every month of follow-up, the mean monofilament value decreased by 0.083 in innervated flaps (p < 0.001) and 0.012 in noninnervated flaps (p < 0.001). Nerve coaptation significantly improved sensation in both immediate and delayed reconstructions. CONCLUSIONS: This study demonstrated that nerve coaptation in DIEP flap breast reconstruction is associated with a significantly better sensory recovery in all areas of the reconstructed breast compared with noninnervated flaps. The length of follow-up was significantly associated with the sensory recovery.
