The prevention of chemotherapy-induced alopecia still represents an urgent need for every day clinical practice. In this regard, this prospective single-center study included breast cancer (BC) patients who underwent a scalp cooling device (Dignicap®) during (neo)adjuvant chemotherapy with the aim to evaluate the efficacy and safety of this device in preventing alopecia. One hundred and seventy-eight patients (median age 43 years) were enrolled. The chemotherapy regimen included anthracycline and taxane-based chemotherapy (68.1%), docetaxel and cyclophosphamide (25.8%), anthracycline and taxane-based plus carboplatin (3.9%), and paclitaxel alone (2.2%). In 25.3% of cases, a dose dense schedule was used. Overall, the success rate was 68.0%: 100% in paclitaxel alone, 87.0% in docetaxel-cyclophosphamide, 59.5% in anthracycline and taxane, and 71.4% in the sequential regimen plus carboplatin group (anthracycline and taxane-based chemotherapy versus taxane-based chemotherapy, p ≤ 001. No difference in terms of hair preservation between dose-dense or standard schedule was found (p = 0.557). Early discontinuation of the scalp cooling was observed in 50 patients (28.1%). Although 138 patients (77.5%) experienced adverse events, 70.2% of patients were satisfied with this device. In conclusion, this large prospective study confirmed the helpful effect of the scalp cooling system in preventing alopecia in BC patients also undergoing sequential anthracyclines and taxane-based chemotherapy.

Objective: The objective of this retrospective study was to investigate the accuracy and feasibility of magnetic seed compared to skin tattoo in preoperative localization of impalpable breast lesions in terms of accuracy of placement, re-excision and positive margins rates, and breast/surgical specimen volume ratio. Methods: We retrospectively analyzed 77 patients who underwent breast conservative surgery in our center from November 2020 to November 2021, with previous localization with skin tattoo or magnetic seed. Results: Thirty-seven magnetic seeds were placed in 36 patients (48.6%) and 40 skin tattoos were performed in the remaining cases (51.4%). The seeds were placed correctly at the two-view mammogram acquired after the insertion in 97.6% (36/37) of cases. With both methods, 100% of the index lesions were completely removed and found in the surgical specimen. The reported re-excision rate was 0% for both groups. A significant difference was observed in the volume of breast parenchyma removed between the two groups, inferior in the seed group (p = 0.046), especially in case of voluminous breasts (p = 0.003) and small lesions (dimension < 8 mm, p = 0.019). Conclusions: Magnetic seed is a non-radioactive localization technique, feasible to place, recommended in case of non-palpable breast lesions, saving the breast parenchyma removed compared with skin tattoo, without reducing the accuracy. Clinical relevance statement: Our findings contribute to the current evidence on preoperative localization techniques for non-palpable breast lesions, highlighting the efficacy of magnetic seed localization for deep and small lesions. Key points: • Magnetic seed is a non-radioactive technique for the preoperative localization of non-palpable breast lesions studied in comparison with skin tattoo. • Magnetic seed is feasible to place in terms of post-placement migration and distance from the target lesion. • Magnetic seed is recommended in case of non-palpable breast l

Background: The diffusion of screening programs has resulted in a decrease of cT4 breast cancer diagnosis. The standard care for cT4 was neoadjuvant chemotherapy (NA), surgery, and locoregional or adjuvant systemic therapies. NA allows two outcomes: 1. improve survival rates, and 2. de-escalation of surgery. This de-escalation has allowed the introduction of conservative breast surgery (CBS). We evaluate the possibility of submitting cT4 patients to CBS instead of radical breast surgery (RBS) by assessing the risk of locoregional disease-free survival, (LR-DFS) distant disease-free survival (DDFS), and overall survival (OS). Methods: This monocentric, retrospective study evaluated cT4 patients submitted to NA and surgery between January 2014 and July 2021. The study population included patients undergoing CBS or RBS without immediate reconstruction. Survival curves were obtained using the Kaplan-Meyer method and compared using a Log Rank test. Results: At a follow-up of 43.7 months, LR-DFS was 70% and 75.9%, respectively, in CBS and RBS (p = 0.420). DDFS was 67.8% and 29.7%, respectively, (p = 0.122). OS was 69.8% and 59.8%, respectively, (p = 0.311). Conclusions: In patients with major or complete response to NA, CBS can be considered a safe alternative to RBS in the treatment of cT4a-d stage. In patients with poor response to NA, RBS remained the best surgical choice.

Triple-negative breast cancer (TNBC) is an aggressive type of breast cancer that lacks the expression of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2). TNBC accounts for about 15% of breast cancers and has a poorer prognosis as compared with other subtypes of breast cancer. The more rapid onset of this cancer and its aggressiveness have often convinced breast surgeons that mastectomy could provide better oncological results. However, there is no relevant clinical trial that has assessed differences between breast-conserving surgery (BCS) and mastectomy (M) in these patients. This population-based study aimed to investigate the distinct outcomes between conservative treatment and M in a case series of 289 patients with TNBC treated over a 9-year period. This monocentric study retrospectively evaluated patients with TNBC who underwent upfront surgery at Fondazione Policlinico Agostino Gemelli IRCCS, in Rome, between 1 January 2013 and 31 December 2021. First, the patients were divided in two groups according to the surgical treatment received: BCS vs. M. Then, the patients were stratified into four risk subclasses based on combined T and N pathological staging (T1N0, T1N+, T2-4N0 and T2-4N+). The primary endpoint of the study was to evaluate locoregional disease-free survival (LR-DFS), distant disease-free survival (DDFS) and overall survival (OS) in the different subclasses. We analyzed 289 patients that underwent either breast-conserving surgery (247/289, 85.5%) or mastectomy (42/289, 14.5%). After a median follow-up of 43.2 months (49.7, 22.2–74.3), 28 patients (9.6%) developed a locoregional recurrence, 27 patients (9.0%) showed systemic recurrence and 19 patients (6.5%) died. No significant differences due to type of surgical treatment were observed in the different risk subclasses in terms of locoregional disease-free survival, distant disease-free survival and overall survival. With the limits of a retros

Sentinel lymph node biopsy (SLNB) following neoadjuvant treatment (NACT) has been questioned by many studies that reported heterogeneous identification (IR) and false negative rates (FNR). As a result, some patients receive axillary lymph node dissection (ALND) regardless of response to NACT, leading to a potential overtreatment. To better assess reliability and clinical significance of SLNB status on ycN0 patients, we retrospectively analyzed oncological outcomes of 399 patients treated between January 2016 and December 2019 that were either cN0-ycN0 (219 pa-tients) or cN1/2-ycN0 (180 patients). The Endpoints of our study were to assess, furthermore than IR: oncological outcomes as Overall Survival (OS); Distant Disease Free Survival (DDFS); and Regional Disease Free Survival (RDFS) according to SLNB status. SLN identification rate was 96.8% (98.2% in patients cN0-ycN0 and 95.2% in patients cN+-ycN0). A median number of three lymph nodes were identified and removed. Among cN0-ycN0 patients, 149 (68%) were confirmed ypN0(sn), whereas regarding cN1/2-ycN0 cases 86 (47.8%) confirmed an effective downstaging to ypN0. Three year OS, DDFS and RDFS were significantly related to SLNB positivity. Our data seemed to confirm SLNB feasibility following NACT in ycN0 patients, furthermore reinforcing its predictive role in a short observation timing.

Background: Conservative mastectomy with immediate prosthetic breast reconstruction (IPBR) is an oncologically accepted technique that offers improved esthetic results and patient quality of life. Traditionally, implants have been placed in a submuscular (SM) plane beneath the pectoralis major muscle (PMM). Recently, prepectoral (PP) placement of the prosthesis has been increasingly used in order to avoid morbidities related to manipulation of the PMM. The aim of this study was to compare outcomes of SM vs. PP IPBR after conservative mastectomy in patients with histologically proven breast cancer treated with neoadjuvant chemotherapy (NAC). Methods: In this retrospective observational study, we analyzed two cohorts of patients that underwent mastectomy with IPBR after NAC in our institution from January 2018 to December 2021. Conservative mastectomy was performed in 146 of the 400 patients that underwent NAC during the study period. Patients were divided into two groups based on the positioning of implants: 56 SM versus 90 PP. Results: The two cohorts were similar for age (mean age 42 and 44 years in the SM and PP group respectively) and follow-up (33 and 20 months, respectively). Mean operative time was 56 min shorter in the PP group (300 and 244 min in the SM and PP group). No significant differences were observed in overall major complication rates. Implant loss was observed in 1.78% of patients (1/56) in the SM group and 1.11% of patients (1/90) in PP group. No differences were observed between the two groups in local or regional recurrence. Conclusions: Our preliminary experience, which represents one of the largest series of patients undergoing PP-IPBR after NAC at a single institution documented in the literature, seems to confirm that PP-IPBR after NAC is a safe, reliable and effective alternative to traditional SM-IPBR with excellent esthetic and oncological outcomes; it is easy to perform, reduces operative time and minimizes complications related to manip

Oncoplastic level II breast-conserving surgery (OPS2) allows for wider excisions than standard breast-conserving surgery, but the literature on this technique in the treatment of DCIS is scarce. This study compares OPS2 to conservative mastectomy (CM) in patients undergoing surgery for large DCIS. The clinical, radiological, surgical, and post-operative data of 147 patients who underwent either CM or OPS2 for large DCIS between 2007 and 2021 were retrospectively reviewed. The surgical, oncological, and patient-reported outcomes (PRO) were analyzed and compared between the two groups. The surgical outcomes were similar, in terms of margin involvement (p = 0.211), complication rate (p = 0.827), and re-excision rate (p = 1). The rate of additional surgery for cosmetic optimization was significantly lower in the OPS2 group: only 1 (1.8%) patient required surgical adjustments versus 24 (26.4%) patients in the CM group (p < 0.001). The mean hospital stay was lower in the OPS2 group (p < 0.001). The oncological outcomes did not differ between the two groups (p = 0.662). The PRO analysis showed better outcomes in the OPS2 group, which achieved statistical significance in the sexual well-being module (p = 0.015). Skin sensitivity loss was also significantly lower in the OPS2 group (p < 0.001). When feasible, OPS2 should be considered in the treatment of large DCIS, as it is safe and shows high levels of patient satisfaction.

Oncoplastic surgery level II techniques (OPSII) are used in patients with operable breast cancer. There is no evidence regarding their safety and efficacy after neoadjuvant chemotherapy (NAC). The aim of this study was to compare the oncological and aesthetic outcomes of this technique compared with those observed in mastectomy with immediate breast reconstruction (MIBR), in post-NAC patients undergoing surgery between January 2016 and March 2021. Local disease-free survival (L-DFS), regional disease-free survival (R-DFS), distant disease-free survival (D-DFS), and overall survival (OS) were compared; the aesthetic results and quality of life (QoL) were evaluated using BREAST-Q. A total of 297 patients were included, 87 of whom underwent OPSII and 210 of whom underwent MIBR. After a median follow-up of 39.5 months, local recurrence had occurred in 3 patients in the OPSII group (3.4%), and in 13 patients in the MIBR group (6.1%) (p = 0.408). The three-year L-DFS rates were 95.1% for OPSII and 96.2% for MIBR (p = 0.286). The three-year R-DFS rates were 100% and 96.4%, respectively (p = 0.559). The three-year D-DFS rate were 90.7% and 89.7% (p = 0.849). The three-year OS rates were 95.7% and 95% (p = 0.394). BREAST-Q highlighted significant advantages in physical well-being for OPSII. No difference was shown for satisfaction with breasts (p = 0.656) or psychosocial well-being (p = 0.444). OPSII is safe and effective after NAC. It allows oncological and aesthetic outcomes with a high QoL, and is a safe alternative for locally advanced tumors which are partial responders to NAC.

BACKGROUND: Treatment of de-novo metastatic breast cancer is usually centered around systemic therapy, with local therapy (surgery and radiation therapy) largely reserved for palliation in patients with significant symptoms from primary tumor. The efficacy of locoregional treatment like surgery and/or radiotherapy is still controversial and the debate about surgical resection of primary tumor (PT) in de novo metastatic breast cancer (MBC) patients persists. METHODS: All patients with de-novo MBC undergone surgical treatment between January 2015 and January 2020 at the Multidisciplinary Breast Center of the IRCCS A. Gemelli University Polyclinic Foundation in Rome were included in this study. The primary endpoint was overall survival (OS) after PT resection, the secondary endpoint was progression free survival (PFS). The survival analyses were done using Kaplan-Meier method. Patients and tumor characteristics were analyzed in an exploratory modality in order to identify prognostic factor. RESULTS: Forty-five patients received resection of the primary breast cancer (26 mastectomy and 19 breast conserving surgery). Median age of diagnosis was 53 years old (range 25-75 years old). Median follow-up was 25.67 months. The median OS was not reached with 75% of patients alive over 2 years from PT resection. The median PFS was not reached with 64% of patients alive over 2 years from PT resection. For both PFS and OS only the triple negative (TN) immunophenotype appears to be a prognostically unfavorable factor in multivariate analysis. CONCLUSIONS: In view of the low number of disease progression events and deaths, although our results are preliminary, surgical treatment of primary breast cancer in metastatic setting seems to be an option after systemic therapies in luminal and HER2 positive breast cancer. Randomized prospective trials for each immunophenotype are necessary in order to confirm this evidence.

The diagnosis of breast cancer (BC) during pregnancy is uncommon. It has varied among different studies from 1:10,000 to 1:3000 of all pregnancies, with a median age of 33 years. Pregnancy-associated BC represents a challenge in terms of clinical management to guarantee both maternal and fetal security in choosing the right treatment. This situation is complex and requires a multidisciplinary approach, including the surgeon, anesthesiologist, oncologist, radiotherapist, psychologist, and maternal–fetal medicine specialist. In the present review, we examined the management of pregnancy-associated BC, focusing on pathophysiologic background, risk factors, diagnosis, staging procedures, anesthesia, surgical management, and systemic treatment.

BACKGROUND: Nipple-sparing mastectomy (NSM) with immediate prosthetic breast reconstruction (IPBR) is an oncologically accepted technique that allows to improve aesthetic results and patient quality of life. Traditionally, implant for reconstruction have been placed in a submuscolar (SM) plane, beneath the pectoralis major muscle (PMM). Recently, prepectoral (PP) placement of prosthesis is increasingly used in order to avoid morbidities related to manipulation of PMM. The aim of the present study was to report our experience with 209 NSMs and IPBR using a prepectoral approach and polyurethane-coated implant without acellular dermal matrices (ADMs). METHODS: A retrospective review of breast cancer patients who underwent NSM followed by PP - IPBR from January 2018 to April 2021 was performed. Data were recorded in order to evaluate operative details, major complications and oncological outcomes. Aesthetic results and patient quality of life were measured by a specific “QOL assessment PRO” survey. RESULTS: Two hundred and nine patients (269 breasts) with PP - IPBR after NSM were included. Mean age was 47 (25-73) years and median follow-up was 14 (1-40) months. A simultaneous contralateral implant-based mammoplasty of symmetrization after unilateral NSM was carried out in six of 149 (4%) patients. Implant loss was observed in three of 209 patient (1.44%); two of 209 (0.96%) patients developed a full-thickness NAC necrosis that required excision. During follow-up one local relapse (0.48%) and two regional nodes recurrences (0,96%) was observed. Patient satisfaction, assessed using a personalized QOL Assessment PRO survey, in term of aesthetic results, chronic pain, shoulder dysfunction, sports activity, sexual and relationship life and skin sensibility, was excellent. CONCLUSIONS: Our experience shows that PP-IPBR using polyurethane-coated implant after NSM is a safe, reliable and effective alternative to traditional IPBR with excellent aesthetic outcomes and high patien

Neoadjuvant chemotherapy is increasingly being employed in the management of breast cancer patients. Efforts and resources have been devoted over the years to the search for an optimal strategy that can improve outcomes in the neoadjuvant setting. Today, a multidisciplinary approach with the application of evidence-based medicine is considered the gold standard for the improvement of oncological results and patient satisfaction. However, several clinical complications and psychological issues due to various factors can arise during neoadjuvant therapy and undermine outcomes. To ensure that health care needs are adequately addressed, clinicians must consider that women with breast cancer have a high risk of developing “unmet needs” during treatment, and often require a clinical intervention or additional care resources to limit possible complications and psychological issues that can occur during neoadjuvant treatment. This work describes a multidisciplinary model developed at “Fondazione Policlinico Universitario Agostino Gemelli” (FPG) in Rome in an effort to optimize treatment, ease the application of evidence-based medicine, and improve patient quality of life in the neoadjuvant setting. In developing our model, our main goal was to adequately meet patient needs while preventing high levels of distress.

Background: The aim of this study was to compare outcomes of immediate prosthetic breast reconstruction (IPBR) using traditional submuscular (SM) positioning of implants versus prepectoral (PP) positioning of micropolyurethane-foam-coated implants (microthane) without further coverage. Methods: We retrospectively reviewed the medical records of breast cancer patients treated by nipple-sparing mastectomy (NSM) and IPBR in our institution during the two-year period from January 2018 to December 2019. Patients were divided into two groups based on the plane of implant placement: SM versus PP. Results: 177 patients who received IPBR after NSM were included in the study; implants were positioned in a SM plane in 95 patients and in a PP plane in 82 patients. The two cohorts were similar for mean age (44 years and 47 years in the SM and PP groups, respectively) and follow-up (20 months and 16 months, respectively). The mean operative time was 70 min shorter in the PP group. No significant differences were observed in length of hospital stay or overall major complication rates. Statistically significant advantages were observed in the PP group in terms of aesthetic results, chronic pain, shoulder dysfunction, and skin sensibility (p < 0.05), as well as a trend of better outcomes for sports activity and sexual/relationship life. Cost analysis revealed that PP-IPBR was also economically advantageous over SM-IPBR. Conclusions: Our preliminary experience seems to confirm that PP positioning of a polyurethane-coated implant is a safe, reliable and effective method to perform IPBR after NSM.

OBJECTIVE: Triple-negative breast cancers (TNBC) include a heterogeneous group of diseases, characterized by the lack of estrogen receptor (ER), progesterone receptor (PgR), and human epidermal growth factor receptor 2 (HER2) expression. TNBC that shows an overexpression of the androgen receptor (AR) defines the phenotype known as “luminal androgen receptor” (LAR), while the absence of the AR defines a “quadruple negative breast cancer” (QNBC). Several reports have associated AR positivity with a lower response to neoadjuvant chemotherapy (NAC), while divergent data have been reported about the impact of AR positivity on survival. The aim of this study was to retrospectively review our series of patients with TNBC tested for AR and submitted to NAC and compare pathologic complete response (pCR) rates in patients with a LAR phenotype or with QNBC. PATIENTS AND METHODS: The clinical records of all patients with TNBC tested for AR that underwent NAC at our Institution from January 1, 2015 to June 30, 2019 were reviewed. Histopathological features as well as ER, PgR, Ki67, HER2 values, clinical and pathological stage, and results of BRCA gene expression profiling were registered for all patients. RESULTS: Of the 145 TNBC patients treated by NAC, 20 (13.8%) had a LAR phenotype, while 125 (86.2%) had a QNBC. Overall, a pCR was achieved in 52 patients (35.8%). Patients with LAR phenotype had a lower rate of pCR as compared to patients with QNBC phenotype (25% vs. 37.6%). High Ki67 values (>50%) were observed less frequently in patients with a LAR phenotype (50% vs. 76.8% in QNBC). CONCLUSIONS: Our data seem to confirm that the LAR phenotype is associated to lower rates of pCR after neoadjuvant chemotherapy; routine assessment of AR expression in addition to classical biomarkers in patients with TNBC could help to better personalize treatment.

Background: During the 2016 Assisi Think Tank Meeting (ATTM) on breast cancer, the panel of experts proposed developing a validated system, based on rapid learning health care (RLHC) principles, to standardize inter-center data collection and promote personalized treatments for breast cancer. Material and Methods: The seven-step Breast LArge DatabasE (BLADE) project included data collection, analysis, application, and evaluation on a data-sharing platform. The multidisciplinary team developed a consensus-based ontology of validated variables with over 80% agreement. This English-language ontology constituted a breast cancer library with seven knowledge domains: baseline, primary systemic therapy, surgery, adjuvant systemic therapies, radiation therapy, followup, and toxicity. The library was uploaded to the BLADE domain. The safety of data encryption and preservation was tested according to General Data Protection Regulation (GDPR) guidelines on data from 15 clinical charts. The system was validated on 64 patients who had undergone post-mastectomy radiation therapy. In October 2018, the BLADE system was approved by the Ethical Committee of Fondazione Policlinico Gemelli IRCCS, Rome, Italy (Protocol No. 0043996/18). Results: From June 2016 to July 2019, the multidisciplinary team completed the work plan. An ontology of 218 validated variables was uploaded to the BLADE domain. The GDPR safety test confirmed encryption and data preservation (on 5000 random cases). All validation benchmarks were met. Conclusion: BLADE is a support system for follow-up and assessment of breast cancer care. To successfully develop and validate it as the first standardized data collection system, multidisciplinary collaboration was crucial in selecting its ontology and knowledge domains. BLADE is suitable for multi-center uploading of retrospective and prospective clinical data, as it ensures anonymity and data privacy.

Breast conserving surgery has become the standard of care and is more commonly performed than mastectomy for early stage breast cancer, with recent studies showing equivalent survival and lower morbidity. Accurate preoperative lesion localization is mandatory to obtain adequate oncological and cosmetic results. Image guidance assures the precision requested for this purpose. This review provides a summary of all techniques currently available, ranging from the classic wire positioning to the newer magnetic seed localization. We describe the procedures and equipment necessary for each method, outlining the advantages and disadvantages, with a focus on the cost-effective preoperative skin tattoo technique performed at our centre. Breast surgeons and radiologists have to consider ongoing technological developments in order to assess the best localization method for each individual patient and clinical setting.

OBJECTIVE: To predict the occult tumor involvement of nipple-areola complex (NAC) using preoperative MR imaging and to investigate whether the intraoperative histopathological examination of the subareolar tissue is still necessary.PATIENTS AND METHODS: Out of 712 patients submitted to nipple-sparing mastectomy (NSM) between 2014 and 2019, we selected 188 patients who underwent preoperative breast MRI. Breast MRI and intraoperative histopathological examination of the subareolar tissue were performed to predict NAC involvement at permanent pathology. All parameters were correlated with final pathological NAC assessment by univariate and multivariate analysis.RESULTS: Forty-three patients (22.9%) had tumor involvement of the NAC. At univariate analysis, non-mass enhancement type (p = 0.009), multifocality/multicentricity (p = 0.002), median tumor size (p < 0.001), median tumor-NAC distance measured by MRI (p < 0.001), tumor-NAC distance ≤ 10 mm (p < 0.001) and tumor-NAC distance ≤ 20 mm (p < 0.001), and lymphovascular invasion (p = 0.001) were significantly correlated with NAC involvement. At multivariate analysis, only tumor-NAC distance ≤ 10 mm retained statistical significance. The sensitivity and specificity of MRI tumor-NAC distance ≤ 10 mm were 79.1% and 97.2% and those of intraoperative pathologic assessment were 74,4% and 100%, respectively.CONCLUSIONS: Tumor-NAC distance is the only reliable MRI characteristic that can predict NAC involvement in breast cancer patients. Although several cut-offs showed promising performances, intraoperative pathologic assessment is still mandatory.

Ductal carcinoma in situ (DCIS) represents a disease that includes different risk categories and does not necessarily turn into invasive cancer. The 20% of all newly diagnosed breast cancers consist in DCIS, with an incidence increased due to the widespread diffusion of screening programs. Once upon a time, mastectomy was considered the gold standard in treatment of DCIS, but over the years, breast-conserving surgery (BCS) has been included as the treatment of choice for patients with small lesions. Several randomized trials demonstrated that adjuvant treatment as radiation and ET reduce the risk of local recurrence, including invasive recurrences. Therefore, in patients with DCIS susceptible to conservative surgery, the key decision for management is represented by the addition of radiotherapy (RT) or ET. With the variety of surgical and adjuvant treatment options available, there has been great interest in tailoring therapies to the individual, with the goal of optimizing the balance of risks and benefits. From the observation of the first data showing how such treatments are not clearly associated with an improvement in disease specific mortality, the upcoming hypothesis is to consider omitting some of such treatments or to plan close surveillance for low risk lesions. Prospective studies on women treated with BCS alone have identified low risk lesions. Actually, the main challenge is how to recognize cases that will not progress to invasive lesions. Despite all the studies carried out and the many available data, there are no unique and universally accepted treatment criteria, so some issues of controversy are still open.

Nowadays, the overall attention is focused on de-escalating treatments for breast cancer (BC) including surgery, radiotherapy and chemotherapy. The introduction of sentinel lymph node biopsy (SLNB) has led to less invasive surgical approaches for accurately staging the axilla, with axillary lymph node dissection (ALND) progressively confined to a limited group of patients. One of the goal of surgery in de-escalating approaches is to reduce surgical morbidity by restricting or avoiding axillary surgery with no effect on survival. In this context the importance of imaging study for preoperative identification of axillary metastasis, in order to reduce axillary surgery, is gradually improving while the role of intraoperative assessment of sentinel nodes is progressively becoming limited to restricted groups of patients. According to the results of the ACOSOG Z0011 and following the most important guidelines, ALND can be safely omitted in selected patients treated with breast conserving surgery (BCS) with one or two positive SLNB while the adoption of SLNB positive alone in patients undergoing mastectomy is not yet defined. The increased employment of neoadjuvant chemotherapy (NAC) and the use of SLNB in patients after NAC plays an important role in de-escalation of axillary surgery in this group of patients. However current studies on this topic are still controversial, mainly about clinically positive lymph nodes (cN+) pre NAC patients or how to manage positive SLNB in post NAC patients. Some authors have collected predictive factors of positive non sentinel lymph nodes (NSLNs) in nomograms, considered an useful tool to avoid unnecessary further surgery. Elderly women represent specific group of patients where the axillary approach needs to be properly resized. The management of axilla in BC is in continuous evolution and ongoing studies could make even SLNB useless in the next future.

Scopo dello studio è stato quello di analizzare l’influenza del rapporto tra volume del tumore/volume della mammella (TV/BV), misurato nelle immagini di risonanza magnetica (MRI) e di altri fattori sulla scelta del trattamento chirurgico -chirurgia oncoplastica (LVOS) versus mastectomia (M)- nelle pazienti con neoplasia mammaria localmente avanzata. Ulteriore obiettivo è stato inoltre di analizzare il valore predittivo del rapporto TV/BV e di altri possibili fattori sull’esito cosmetico. Sono stati retrospettivamente analizzati i dati di 80 esami di risonanza magnetica eseguiti su 77 pazienti con neoplasia mammaria localmente avanzata sottoposte successivamente a M (58 mammelle, 72,5%) o LVOS (22 mammelle, 27,5%) da gennaio 2016 a dicembre 2017. Il TV e il BV sono stati calcolati sulle immagini di risonanza magnetica mediante un’analisi semiautomatica e il rapporto TV/BV è stato calcolato dividendo il TV per il BV (espressi in cm3) e moltiplicando per 1000. L’esito cosmetico è stato valutato da un panel di esperti mediante l’utilizzo di fotografie post-operatorie. IL rapporto TV/BV è significativamente più alto nel gruppo delle pazienti sottoposte a M (44,8 IQR 17,3-93,6) rispetto al gruppo LVOS (17,5 IQR 11,7-57,5) (P=0.002). Una malattia multifocale/multicentrica (P=0.005), un minore grado di ptosi (P<0.0001) e una sfavorevole localizzazione del tumore (P=0.024) sono significativamente più frequenti nelle pazienti sottoposte a M. Dopo analisi di regressione lineare multivariata, i fattori indipendenti predittivi di risultato cosmetico scadente risultano: una sfavorevole localizzazione del tumore (OR 6.637 95% CI 1.564–28.172 P=0.010) e un alto rapporto TV/BV (OR 4.907 95% CI 1.461–16.478 P=0.010). Le valutazioni preoperatorie riguardo il rapporto TV/BV, la localizzazione della neoplasia e la sua multifocalità/ multicentricità consentono di migliorare il processo decisionale nella scelta del trattamento chirurgico (mastectomia vs LVOS) nelle pazienti el, PURPOSE: To analyse the influence of tumor volume/breast volume ratio (TV/BV ratio) measured on magnetic resonance imaging (MRI) and other factors on surgeons' choice between large volume displacement oncoplastic surgery (LVOS) versus mastectomy (M) in patients with large sized tumors. Secondly, we investigate the predictive value of TV/BV ratio and other possible predictors for cosmetic results. MATERIALS AND METHODS: We retrospectively reviewed 80 MRI examinations performed on 77 breast cancer patients who underwent M (58 breasts, 72.5%) or LVOS (22 breasts, 27.5%) at our institution between January 2016 and December 2017. The TV and BV measurements were performed by a semiautomated analysis and the TV/BV ratio was calculated by dividing TV by BV in cm3 and multiplying it by 1,000. Cosmetic result was determined by an expert panel assessment of postoperative photographs. RESULTS: Median TV/BV was significantly higher in the M group (44,8 IQR 17,3-93,6) than in the LVOS group (17,5 IQR 11,7-57,5) (P=0.002). Multifocal/multicentric disease (P=0.005), lower degree of breast ptosis (P<0.0001) and unfavourable tumor location (P=0.024) are significantly more frequent in the M group. After multivariable linear regression, the independent predictors for cosmetic result were: unfavourable tumor location (OR 6.637 95% CI 1.564- 28.172 P=0.010) and a higher TV/BV ratio (OR 4.907 95% CI 1.461-16.478 P=0.010) CONCLUSION: Preoperative evaluation of TV/BV ratio, tumor location and tumor multifocality/multicentricity could improve treatment decision making (LVOS versus M) in breast cancer patient eligible for both options. Increasing TV/BV ratio and unfavourable tumor location are adversely affecting cosmetic result.

Introduction: Nipple-sparing mastectomy (NSM) has known an exponential diffusion worldwide for prophilaxis and therapeutic mastectomies in selected candidates, being oncologically safe and improving reconstructive outcomes and patients' satisfaction. The two most common used skin incisions are the radial and inframammary fold ones, which represent an imperfect aesthetic solution. The aim of this work was to give insights on our surgical technique, which allows to perform the NSM, node surgery, and endoscopic direct-to-implant reconstruction using a cosmetic axillary incision. Materials and methods: Between June 2016 and January 2019, 7 consecutive patients underwent NSM, lymph node surgery and endoscopic direct-to-implant reconstruction using a small cosmetic axillary incision for breast cancer treatment in a single Institution. An operative rigid endoscope with working channel (Richard Wolf) was used to dissect the entire submuscular-subfascial pocket. The mean age of the patients was 42.8 years old (range: 36-49 years). The evaluation methods were clinical and photography-based assessments, as well as the BREAST-Q which was used to quantify patient satisfaction. Results: The average follow-up time was 9 months (range 3-22 months). Tumor-free margins were obtained in all cases. No tumor recurrence or metastasis occurred during follow-up. No major complications were experienced. There were no cases of malposition, wrinkling, or rippling. All patients were satisfied with their esthetic results, especially the absence of visible scars. Conclusions: From our preliminary experience, NSM combined with endoscopic immediate reconstruction via axillary incision for breast cancer treatment seems to be a promising new procedure in cup A and B breasts alternative to the conventional techniques, as it allowed to have safe and pleasant aesthetic and oncologic outcomes.

Purpose: Screening mammogram reading volume (SMRV) and total (screening and clinical) mammogram reading volume (TMRV) per year are strongly associated with the radiologist’s diagnostic performance in breast cancer screening. The current article reports the prevalence and correlates of a SMRV and a TMRV ≥5000 among Italian breast screening radiologists. Materials and methods: A questionnaire survey was carried out in 2013–2014 by the Italian Group for Mammography Screening (GISMa). The questionnaire included items of information for radiologist’s experience-related characteristics and for facility-level factors supposedly associated with SMRV and TMRV. Multivariate analysis was performed using backward stepwise multiple logistic regression models. Results: Data for 235 radiologists from 51 local screening programmes were received. Of the 222 radiologists who were eligible, 133 (59.9 %) reported a SMRV ≥5000 and 163 (73.4 %) a TMRV ≥5000. Multivariate factors positively associated with both characteristics included: the number of years of experience reading mammograms; the percentage of total working time dedicated to breast imaging and breast care; the participation in diagnostic assessment; and the availability of digital tomosynthesis at facility. Full-time dedication to breast imaging and breast care was associated with the highest odds ratio for a SMRV and a TMRV ≥5000, i.e. 11.80 and 46.74, respectively, versus a percentage of time ≤50 %. An early (<2000) year of implementation of the screening programme and the availability of vacuum-assisted biopsy at facility were associated with a SMRV and, respectively, a TMRV ≥5000. Conclusions: Increasing the proportion of radiologists with full-time dedication to breast imaging and breast care qualified as the most effective approach to improve SMRV and TMRV.

Pathogenic mutations in two autosomal dominant genes, BRCA1 and BRCA2, with high penetrance are supposed to be the cause for an approximated 5-7% risk of all breast cancer (BC) and ovarian cancer (OC). Compared to sporadic BC, BRCA mutated (BRCAmut) BC differs for lifetime risk of onset and sensitivity to systemic therapies. A hereditary BC syndrome should be taken into account when there are numerous relatives with BC early-onset (typically before menopause). Moreover, BRCAmut carriers showed a lifetime possibility of manifesting OC. When a BC diagnosis is made in young patients or in suspicious personal relatives' anamnesis, be aware of being carriers of a BRCA mutation may influence the decision making-process about surgical procedure and prevention strategies. In this review, we examined surgical treatment choice for BRCAmut BC, risk of ipsilateral breast recurrence (IBR) and contralateral breast cancer (CBC). We examined the role of breast-conserving therapy (BCT), risk-reducing mastectomy (RRM) and preventive risk-reducing salpingo-oophorectomy (RRSO) with a special consideration about advantage in terms of mortality reduction for both conservative and prophylactic measures. We also reviewed the sensitivity of mutated BC to platinum-based antineoplastic drugs and poly (ADP-ribose) polymerase inhibitors (PARPi) by emphasizing the results of clinical trials recently published.

Introduction. In Italy, due to increasing healthcare budget and staff shortages, the recently created regional mammography screening programmes were established under worse radiology practice quality criteria than the previously created programmes. Methods. Using available data from a national questionnaire survey conducted at the end of 2013 and involving 222 responder radiologists, we compared the main professional quality standards of radiologists working in the screening programmes established during the period 2000-2012 with those working in the screening programmes created from 1990 to 1999. Results. The former reported more years of clinical experience in breast imaging and a greater clinical mammogram reading volume than the latter. Conversely, they dedicated less working time to breast imaging, were less likely to participate in the diagnostic assessment of screen-detected lesions, to work in large-staffed screening centres, and to have a screening and a total mammogram reading volume (SMRV and TMRV) ≥ 5000 per year. Conclusions. The level of most professional quality criteria of Italian mammography screening radiologists has decreased over time. As SMRV and TMRV are important predictors of diagnostic accuracy, we can expect a lower interpretation performance of radiologists working in the recently created screening programmes.

In the attempt to optimise the balance between the risk of local recurrence and the cosmetic outcomes in breast surgery, new surgical procedures, so-called oncoplastic techniques, have been introduced in recent years. The term oncoplastic surgery refers to surgery on the basis of oncological principles during which the techniques of plastic surgery are used, mostly for reconstructive and cosmetic reasons. The advantage of the oncoplastic surgery for breast cancer is the possibility of performing a wider excision of the tumour with a good cosmetic result. Oncoplastic surgery is a broad concept that can be used for several different combinations of oncological surgery and plastic surgery: excision of the tumour by reduction mammoplasty, tumour excision followed by remodelling mammoplasty, mastectomy with immediate reconstruction of the breast and partial mastectomy with reconstruction. Careful patient selection and preoperative planning are key components for the success of any oncoplastic operation for breast cancer. Accurate preoperative evaluation of the clinical and biological features of the tumour as well as of the morphological aspects of the breast allow the surgeon to make a decision if a conservative or radical approach is preferable and select the most effective oncoplastic surgical technique. In this review we summarise the indications, advantages and limitations of several oncoplastic procedures.

Background: Distant spread from breast cancer is commonly found in bones, lungs, liver and central nervous system. Metastatic involvement of peritoneum and retroperitoneum is unusual and unexpected. Case presentation: We report the case of a 67 year-old-woman who presented with gastrointestinal symptoms which revealed to be the clinical manifestations of peritoneal and retroperitoneal metastatic spread of an invasive lobular breast cancer diagnosed 15 years before. Conclusion: To the best of our knowledge, the case presented is the third one reported in literature showing a wide peritoneal and extraperitoneal diffusion of an invasive lobular breast cancer. The long and complex diagnostic work up which led us to the diagnosis is illustrated, with particular emphasis on the multidisciplinary approach, which is mandatory to obtain such a result in these cases. Awareness of such a condition by clinicians is mandatory in order to make an early diagnosis and start a prompt and correct therapeutic approach. © 2006 Franceschini et al; licensee BioMed Central Ltd.

Background We evaluated the diagnostic performance of the baseline diffusion weighted imaging (DWI) and the apparent diffusion coefficient (ADC) in the prediction of a complete pathologic response (pCR) to neoadjuvant chemotherapy (NAC) in patients with breast cancer stratified according to the tumor phenotype. Patients and Methods We retrospectively studied 225 patients with stage II, III, and IV breast cancer who had undergone contrast-enhanced magnetic resonance imaging (MRI) and DWI before and after NAC, followed by breast surgery. Results The tumor phenotypes were luminal (n = 143; 63.6%), triple-negative (TN) (n = 37; 16.4%), human epidermal growth factor receptor 2 (HER2)-enriched (n = 17; 7.6%), and hybrid (hormone receptor-positive/HER2+; n = 28; 12.4%). After NAC, a pCR was observed in 39 patients (17.3%). No statistically significant difference was observed in the mean ADC value between a pCR and no pCR in the general population (1.132 ± 0.191 × 10-3 mm2/s vs. 1.092 ± 0.189 × 10-3 mm2/s, respectively; P =.23). The optimal ADC cutoff value in the general population was 0.975 × 10-3 mm2/s (receiver operating characteristic [ROC] area under the curve [AUC], 0.587 for the prediction of a pCR). After splitting the population into subgroups according to tumor phenotype, we observed a significant or nearly significant difference in the mean ADC value among the responders versus the nonresponders in the TN (P =.06) and HER2+ subgroups (P =.05). No meaningful difference was seen in the luminal and hybrid subgroups (P =.59 and P =.53, respectively). In contrast, in the TN and HER2+ subgroups (cutoff value, 0.995 × 10-3 mm2/s and 0.971 × 10-3 mm2/s, respectively), we observed adequate ROC AUCs (0.766 and 0.813, respectively). Conclusion The pretreatment ADC value is not capable of predicting the pCR in the overall population of patients with locally advanced breast cancer. Nonetheless, an ameliorated diagnostic performance was observed in specific phenotype subgroup

AIM: The estimation of response to neoadjuvant chemotherapy (NAC) is useful in the surgical decision in breast cancer. We addressed the diagnostic reliability of conventional MRI, of diffusion weighted imaging (DWI) and of a merged criterion coupling morphological MRI and DWI. Diagnostic performance was analysed separately in different tumor subtypes, including HER2+ (human epidermal growth factor receptor 2)/HR+ (hormone receptor) (hybrid phenotype). MATERIALS AND METHODS: Two-hundred and twenty-five patients underwent MRI before and after NAC. The response to treatment was defined according to the RECIST classification and the evaluation of DWI with apparent diffusion coefficient (ADC). The complete pathological response - pCR was assessed (Mandard classification). RESULTS: Tumor phenotypes were Luminal (63.6%), Triple Negative (16.4%), HER2+ (7.6%) or Hybrid (12.4%). After NAC, pCR was observed in 17.3% of cases. Average ADC was statistically higher after NAC (p<0.001) among patients showing pCR vs. those who had not pCR. The RECIST classification showed adequate performance in predicting the pCR in Triple Negative (area under the receiver operating characteristic curve, ROC AUC=0.9) and in the HER2+ subgroup (AUC=0.826). Lower performance was found in the Luminal and Hybrid subgroups (AUC 0.693 and 0.611, respectively), where the ADC criterion yielded an improved performance (AUC=0.787 and 0.722). The coupling of morphological and DWI criteria yielded maximally improved performance in the Luminal and Hybrid subgroups (AUC=0.797 and 0.761). CONCLUSION: The diagnostic reliability of MRI in predicting the pCR to NAC depends on the tumor phenotype, particularly in the Luminal and Hybrid subgroups. In these cases, the coupling of morphological MRI evaluation and DWI assessment may facilitate the diagnosis.

The inverted-T skin-reducing mastectomy with implant reconstruction represents a very effective reconstructive and cosmetic option in patients with macromastia. However, in this subset of patients, the risk of skin flap necrosis, especially at the T-junction, is significant. In this setting, complete implant coverage with viable tissue beneath the mastectomy skin flaps is essential to reduce morbidity. In this article, the authors retrospectively review their series of 16 skin-reducing mastectomy and immediate one-stage implant reconstructions using the submuscular-subfascial pocket, analyzing the reconstructive issues and cosmetic outcomes.
