Introduction: Breast-conserving surgery (BCS) is a valid method for the reconstruction of partial breast defects, however, there is a great variety of final aesthetic outcomes depending on the location of the tumor in the breast and also on the initial breast volume and the degree of ptosis. Specifically, defects affecting the upper inner/central quadrant represent a reconstructive challenge with not always satisfactory final results. For this purpose, the authors investigated the use of the central mound technique in breast-conserving surgery. The aim of the study was to apply the central mound as an oncoplastic technique and assess the satisfaction rate of the patients. Materials and methods: This was a retrospective study that involved 40 patients (80 breast) underwent breast conserving surgery and contextual bilateral breast remodeling with central mound technique. A pre- and postoperative Breast-Q questionnaire (breast conserving therapy module) was given to all the patients before the surgery, 3 months and 9 months after. The statistical analysis with chi-square test was performed. Results: After 9 months the author found a major increase of all BREAST-Q parameters; the most valuable increments concerned the "Satisfaction with breast" and "Psychosocial well-being." None of the patients experienced a decreased in the quality of life related to the surgical procedure. Conclusion: The authors believe that this technique has useful functional and aesthetic results particularly appreciated by patients with upper pole lesion who have a slightly or moderately breast ptosis and a small cup size.

Background: In Western countries, breast cancer (BC) is the most common cancer in women. Early detection has a positive impact on survival, quality of life, and public health costs. Mammography screening programs have increased early detection rates, but new approaches to more personalized surveillance could further improve diagnosis. Circulating cell-free DNA (cfDNA) in blood could provide a potential tool for early diagnosis by analyzing cfDNA quantity, circulating tumor DNA mutations, or cfDNA integrity (cfDI). Methods: Plasma was obtained from the blood of 106 breast cancer patients (cases) and 103 healthy women (controls). Digital droplet PCR was used for the determination of ALU 260/111 bp and LINE-1 266/97 bp copy number ratio and cfDI. cfDNA abundance was calculated using copies of the EEF1A2 gene. The accuracy of biomarker discrimination was analyzed with receiver operating characteristic curve (ROC). Sensitivity analyses were performed to account for age as a potential confounder. Results: Cases had significantly lower ALU 260/111 or LINE-1 266/97 copy number ratios (median; ALU 260/111 = 0.08, LINE-1 266/97 = 0.20), compared with control (median; ALU 260/111 = 0.10, LINE-1 266/97 = 0.28) (p < 0.001). ROC analysis showed that copy number ratio discriminated cases from controls (area under the curve, AUC = 0.69, 95% CI: 0.62–0.76 for ALU and 0.80, 95% CI: 0.73–0.86 for LINE-1). ROC from cfDI confirmed the better diagnostic performance of LINE-1 compared with ALU. Conclusions: Analysis of LINE-1 266/97 copy number ratio or cfDI by ddPCR appears to be a useful noninvasive test that could aid in early BC detection. Further studies in a large cohort are needed to validate the biomarker.

Purpose: Prediction algorithms estimating survival rates for breast cancer (BC) based upon risk factors and treatment could give a help to the clinicians during multidisciplinary meetings. The aim of this study was to evaluate accuracy and clinical utility of three different scores: the Clinical Treatment Score Post-5 Years (CTS5), the PREDICT Score, and the Nottingham Prognostic Index (NPI). Methods: This is a retrospective cohort analysis conducted on prospectively recorded databases of two EUSOMA certified centers (Breast Unit of Trieste Academic Hospital and of Cremona Hospital, Italy). We included patients with Luminal BC undergone to breast surgery between 2010 and 2015, and subsequent endocrine therapy for 5 years for curative intent. Results: A total of 473 patients were enrolled in this study. ROC analysis showed fair accuracy for NPI, good accuracy for PREDICT, and optimal accuracy for CTS5 (AUC 0.7, 0.76, and 0.83, respectively). The three scores seemed strongly correlated in Spearman's rank correlation coefficient analysis. PREDICT partially overestimated OS in patients undergone to mastectomy, and in pT3-4, G3 tumors. Considering DRFS as a surrogate of OS, CTS5 showed women in intermediate and high risk class had shorter OS too (respectively p = 0.001 and p < 0.001). Combining scores does not improve prognostication power. Conclusion: Mathematical models may help clinicians in decision making (adjuvant therapies, CDK4/6i, genomic test's gray zones). CTS5 has the higher prognostic accuracy in predicting recurrence, while score predicting OS did not show substantial advances, proving that pN, G, and pT are still the most important variables in predicting OS.

Background Breast intraoperative electron radiation therapy (B-IOERT) can be used in clinical practice both as elective irradiation (partial breast irradiation – APBI) in low risk breast cancer patients, and as an anticipated boost. The procedure generally includes the use of a shielding disk between the residual breast and the pectoralis fascia for the protection of the tissues underneath the target volume. The aim of the study was to evaluate the role of intraoperative ultrasound (IOUS) in improving the quality of B-IOERT. Patients and methods B-IOERT was introduced in Trieste in 2012 and its technique was improved in 2014 with IOUS. Both, needle and IOUS were used to measure target thickness and the latter was used even to check the correct position of the shielding disk. The primary endpoint of the study was the evaluation of the effectiveness of IOUS in reducing the risk of a disk misalignment related to B-IOERT and the secondary endpoint was the analysis of acute and late toxicity, by comparing two groups of patients treated with IOERT as a boost, either measured with IOUS and needle (Group 1) or with needle alone (Group 2). Acute and late toxicity were evaluated by validated scoring systems. Results From the institutional patients who were treated between June 2012 and October 2019, 109 were eligible for this study (corresponding to 110 cases, as one patients underwent bilateral conservative surgery and bilateral B-IOERT). Of these, 38 were allocated to group 1 and 72 to group 2. The target thickness measured with the IOUS probe and with the needle were similar (mean difference of 0.1 mm, p = 0.38). The percentage of patients in which the shield was perfectly aligned after IOUS introduction increased from 23% to more than 70%. Moreover, patients treated after IOUS guidance had less acute toxicity (36.8% vs. 48.6%, p = 0.33) from radiation therapy, which reached no statistical significance. Late toxicity turned out to be similar regardless of the use of IOUS guidance: 39.5% vs. 37.5% (p = 0.99). Conclusions IOUS showed to be accurate in measuring the target depth and decrease the misalignment between collimator and disk. Furthermore there was an absolute decrease in acute toxicity, even though not statistically significant, in the group of women who underwent B-IOERT with IOUS guidance.

PURPOSE: Surgical site infection (SSI) is the most common complication of colorectal surgery, resulting in significant burden in terms of morbidity and length of hospital stay. The aims of this study were to establish the incidence of SSI in patients undergoing colorectal surgeries and to identify potentially modifiable risk factors to reduce overall SSI rates. METHODS: This retrospective study analyzed patients who underwent colorectal resection at our Department. Patients were identified using a prospective SSI database. Univariate and multivariate analyses were used to identify risk factors. RESULTS: A total of 687 patients were enrolled in the study and the overall SSI rate was 19.9% (137 patients). Superficial incisional surgical site infections (SSSIs) developed in 52 (7.6%) patients, deep incisional surgical site infections (DSSIs) developed in 15 (2.2%), and organ/space infections (OSIs) developed in 70 (10.1%). Univariate and multivariate analyses confirmed that age, diabetes, emergency surgery, and a high infection risk index are risk factors for SSI. CONCLUSIONS: There are some modifiable and non-modifiable risk factors for SSI. IRI and age are non-modifiable, whereas the timing of surgery and diabetes can be modulated by trying to defer some emergency procedures to elective ones and normalizing the glycemia of diabetic patients.

In the medical literature, the role of breastfeeding and reproductive factors in the risk of breast carcinoma is still an open debate in premenopausal women. We highlight the role of breastfeeding and reproductive factors in luminal A and luminal B, the most frequent breast cancers. This case-control study analyzes a White premenopausal population of 286 breast cancer patients, divided into molecular subtypes, and 578 controls matched by age. Multivariate logistic regression models were used to assess the relationships of breastfeeding and other reproductive factors (age at menarche, parity, age at first pregnancy, number of children) with the risk of breast cancers. Among the variables examined, reproductive factors did not alter the risk of cancer, whereas breastfeeding up to 12 months was a significant protective factor against luminal B breast cancer (multivariate odds ratio: 0.22, 95% confidence interval: 0.09-0.59, P=0.002). In contrast, luminal A cases did not significantly correlate with breastfeeding or other reproductive factors. Breastfeeding up to 12 months is strongly protective against the more aggressive luminal B, but not against the less aggressive luminal A breast cancer in premenopausal White women.

Introduction: Axillary lymph node dissection (ALND) has been considered essential for the staging of breast cancer (BC). As the impact of tumor biology on clinical outcomes is recognized, a surgical de-escalation approach is being implemented. We performed a retrospective study focused on surgical management of the axilla in invasive lobular carcinoma (ILC) versus invasive ductal carcinoma (IDC). Materials and methods: 1151 newly diagnosed BCs, IDCs (79.6%) or ILCs (20.4%), were selected among patients treated at our Breast Cancer Unit from 2012 to 2018. Tumor characteristics and clinical information were collected and predictors of further metastasis after positive sentinel lymph node biopsy (SLNB) analyzed in relation to disease-free survival (DFS) and overall survival (OS). Results: 27.5% of patients with ILC had ≥ 3 metastatic lymph nodes at ALND after positive SLNB versus 11.48% of IDCs (p = 0.04). Risk predictors of further metastasis at ALND were the presence of > 2 positive lymph nodes at SLNB (OR = 4.72, 95% CI 1.15–19.5 p = 0.03), T3–T4 tumors (OR = 4.93, 95% CI 1.10–22.2, p = 0.03) and Non-Luminal BC (OR = 2.74, 95% CI 1.16–6.50, p = 0.02). The lobular histotype was not associated with the risk of further metastasis at ALND (OR = 1.62, 95% CI 0.77–3.41, p = 0.20). Conclusions: ILC histology is not associated with higher risk of further metastasis at ALND in our analysis. However, surgical management decisions should be taken considering tumor histotype, biology and expected sensitivity to adjuvant therapies.

Background The relationship between breast cancer (BC) and thyroid disease (TD) is still controversial. The aim of the study was to investigate the possible coexistence of TD in patients with newly diagnosed BC and its correlation with BC clinical presentation with regard to menopausal status and stage of disease. Methods This is a retrospective cohort study of all patients treated for primary BC between 2014 and 2016 at the Breast Unit of Trieste University Hospital. Clinical charts and reports were reviewed for coexisting thyroid disorders (i.e. hyperthyroidism, hypothyroidism, benign TD, thyroid cancer, thyroid autoimmunity) and menopausal status at the time of BC diagnosis. Biomolecular profile, stage, and grading of BC were also evaluated. Results A total of 786 women and 7 men were included in the study. Co-presence of TD was found in 161(20.3%) cases: of these, 151(19.4%) patients presented benign TD and 10(1.3%) patients presented thyroid carcinoma. Thyroid autoimmunity was found in 51(32%) patients. Regarding thyroid function, 88(55%) patients had hypothyroidism, 19(12%) hyperthyroidism, and 54(33%) normal thyroid function. No statistically significant correlation was found between age and TD (p = 0.16), although TD was more common in women aged ≥60 years. Women with BC diagnosed at pre-menopausal age were more likely to have thyroid autoimmune diseases (45% vs. 29%, p = 0.05). No association was detected among BC molecular profiles with either thyroid autoimmunity (p = 0.26) or altered thyroid function (p = 0.63). High-grade BC was more frequent in women with hyperthyroidism (52.9%, p = 0.04), but the grading was independent from the presence of thyroid autoimmune disease (p = 0.87). BC stage was related to both thyroid autoimmunity (p = 0.04) and thyroid function (p Conclusions According our study results, patients with primary BC present a greater incidence of autoimmunity disorders, especially when diagnosed in the pre-menopausal setting. However, further prospective studies are required to definitively prove causality.

La diagnosi e la gestione dei tumori fillodi della mammella è complessa a causa del basso tasso di incidenza e dell’imprevedibilità del comportamento di questo tipo di neoplasie (meno dell’1% tra tutti i tumori della mammella [1]). L’obiettivo di questo studio è analizzare i casi di tumori filloidi diagnosticati a Trieste nel periodo 2006-2014 al fine di contestualizzare il comportamento particolarmente aggressivo di un tumore fillode maligno insorto in una paziente con pregressi fillodi benigni.

Background: One of the strongest prognostic factor for breast cancer is the regional lymph node status, which can be evaluated intraoperatively by sentinel lymph node biopsy. Many methods (e.g. frozen section, touch imprint cytology (TIC) and one-step nucleic-acid amplification) are available to detect metastatic cells in axillary lymph nodes. The aim of this study is to evaluate the feasibility of using TIC to detect metastatic cells in sentinel lymph nodes. Methods: This is a retrospective single center cohort analysis conducted on prospectively recorded data. The study included all patients admitted to the Department of General Surgery of Trieste University Hospital for invasive clinically node-negative breast cancer who underwent sentinel lymph node assessment by means of TIC. Results: Between January 2015 and December 2016, 343 patients (338 females and 5 males) underwent breast surgery and sentinel lymph node TIC. Patient’s median age was 66 (33-92) years. The sensitivity of TIC was 54% (95% C.I. 39% to 69%), whereas its specificity and accuracy were 99% (95% C.I. 98% to 100%) and 90%, respectively. The median time required to obtain the result was 20 (15-45) min. The overall cost per each TIC analysis was about 20.50€. Conclusion: Touch imprint cytology appears to be a fast, cost-effective and reliable technique to intraoperatively detect breast cancer lymph node metastasis.

Introduzione: Il riconoscimento intra-operatorio delle metastasi nel linfonodo sentinella, in pazienti affetti da cancro della mammella, è utile al fine di procedere ad una linfoadenectomia ascellare immediata nel corso del medesimo intervento. Ciò è fondamentale per evitare una terapia adiuvante tardiva ed un incremento della morbilità e dei costi sanitari. Scopo di tale lavoro è dimostrare che, la metodica citologica “touch-imprint” (TIC), utilizzata presso l’ Azienda Ospedaliero-Universitaria di Trieste, risponde a tale necessità e nel contempo valutarne l’affidabilità. Materiali e metodi: Nel periodo 2009-2012, presso la nostra struttura sono stati operati 690 carcinomi mammari, di cui 479 (69.4%) sono stati selezionati per la ricerca del linfonodo sentinella con radiocolloide. In 347 carcinomi di dimensioni inferiori o uguali a T2 è stata eseguita la metodica citologica TIC; il linfonodo sentinella è stato successivamente sottoposto all’ analisi istologica standard (sezioni seriate ogni 100 micron per ematossilina-eosina e immunoistochimica) che è stato assunta come “gold standard”. Risultati: Su 347 TIC 298 casi erano concordanti con la diagnosi istologica (38 veri positivi e 260 veri negativi). Dei 49 casi risultati falsi negativi, l’analisi definitiva ha dimostrato 28 casi di micrometastasi e 21 casi di macrometastasi, mentre dei 38 casi positivi al TIC, 35 risultavano macrometastasi, 2 micrometastasi e 1 caso di cellule tumorali isolate. La sensibilità e specificità del TIC per macrometastasi sono rispettivamente 64.4% e 100%. Solo 29 casi su 347, pari all’ 8.3%, sono stati sottoposti a radicalizzazione ascellare differita, mentre nel periodo 2005-2008, prima dell’introduzione del TIC,utilizzando l’analisi istologica standard del linfonodo sentinella, tale percentuale era del 18.2%. Discussione e conclusioni: Grazie alla metodica TIC il tasso di dissezioni ascellari in differita è diminuito notevolmente (dal 18.2% all’8.3%). Se gli studi, in corso di validazione definitiva, dimostreranno che la linfoadenectomia ascellare nel trattamento delle micrometastasi non è necessaria, si può ipotizzare che il numero di reinterventi sull’ascella possa ulteriormente ridursi. Nella nostra esperienza, grazie alla discreta sensibilità del TIC per le macrometastasi legata all’ ottima confidenza del patologo con i preparati citologici, è stato possibile migliorare in maniera rilevante l’approccio chirurgico sull’ascella ed il timing oncologico, senza impegno aggiuntivo di risorse economiche.

The authors report resection of a gastric benign tumor through single-incision laparoscopy, guided by peroperative gastroscopy. VIDEO: A 25-year-old man consulted after diagnosis of a 40 × 20 cm(2) endoluminal lesion of the gastric cardia. Preoperative work-up showed a stromal tumor with invasion of the muscular layer. The umbilical scar was incised and, after placement of a purse-string suture, an 11-mm nondisposable trocar was inserted for a 10-mm 30° angled scope. Curved and reusable instruments (Karl Storz-Endoskope, Tuttlingen, Germany) and straight ultrasonic shears (Ethicon Endosurgery, Cincinnati, OH, US) were inserted transumbilically. Peroperative gastroscopy located the lesion on the smaller gastric curvature, 1 cm from the gastroesophageal junction. A stitch was placed in the center of the lesion, and gastroscopic grasper helped in maintaining the limits of resection. Gastrostomy was closed using two converting absorbable running sutures. Because of the curves of the instruments there was no conflict between the instruments' tips inside the abdomen (Fig. 1a), or between the surgeon's hands outside the abdomen (Fig. 1b). Leak test with the gastroscope checked the integrity of the suture. The specimen was retrieved transumbilically in a plastic bag.Operative time was 150 min, and the umbilical incision was less than 15 mm. The patient was discharged after 5 days, and he is doing well 3 months postoperatively.Laparoscopic gastric resection can be safely performed through a single-access. Peroperative gastroscopy permits the limits of resection to be precisely determine, and use of curved and reusable instruments allows surgeon to achieve ergonomic conditions as in classic laparoscopy, without increasing the laparoscopic cost.

The purpose of this study is evaluation of therapeutic impact of magneti c resonance imaging (MRI) in breast cancer patients that cannot be imaged adequately with traditional radiology: dense breasts, microcalcifications suspicious for carcinoma in situ or discordance between mammography and ultra-sound. A review was performed of 493 patients' records: determination of breast MRI effect on c1inical management was made for the selected 70 cases by analysing pre-MRI and post-MRI therapeutic pia ns. Analysis of final pathology was useful to determine if the change in surgical pian prompted by MRI was appropriate. Breast MRI added c1inical information in 52.9% of patients that resulted in 44.3% of management changes that were judged as appropriate in 83.9% of cases. Breast MRI provides additional useful formation, but causes more extensive surgery (40%) with no proven prognostic benefit. MRI should be considered optional in the c1inical staging of breast cancer and performed in selected cases. © 2009 Eisevier Ltd. Ali rights reserved.

Nowadays neuroendocrine breast cancer is a rare entity, though the presence of neuroendocrine cells is often detected within breast cancers. Most of these tumours are associated with conventional ductal or globular breast cancers. We describe the case of neuroendocrine cancer of the breast and discuss its clinical, radiological and cytological aspects.
