Clinical performance of tomosynthesis in one view at the same total dose as standard screen-film mammography is not inferior to digital mammography in two views.

• Digital breast tomosynthesis is becoming adopted as an adjunct to mammography (MX) • DBT (MLO) +MX (CC) is superior to MX (CC+MLO) in lesion detection (overall and benign lesions) • DBT (MLO) +MX (CC) is non-inferior to MX (CC+MLO) in cancer detection • DBT (MLO) +MX (CC) is superior to MX (CC+MLO) in lesion characterization (overall and benign lesions) • DBT (MLO) +MX (CC) is non-inferior to MX (CC+MLO) in characterization of malignant lesions.

In this enriched study population, the combination of single-view MLO tomosynthesis plus single-view CC mammography was non-inferior to that of standard two-view digital mammography in terms of ROC curve area, sensitivity and specificity.

rate of radiological response, patterns of responses in different organs, treatment-related toxicities. We performed a retrospective analysis of sunitinib therapy in genetically-confirmed VHL patients treated at our Institution for multifocal or advanced RCC. From February 2007 to July 2012, 14 VHL patients started first-line sunitinib for recurrent or progressing RCC, mean age 48 years (27-71). Nine patients achieved a partial RECIST response (64.3%); responses were noted not only in renal and hepatic lesions but also in pancreatic nodules. Most lesions showed density reduction, while all CNS haemangioblastoma lesions remained stable. At a median follow-up of 37 months, six patients have progressed and three patients died, with a progression-free rate at 2 years of 71.4%. Sunitinib may therefore achieve a fairly good disease control in VHL patients. Radiological responses may be obtained not only in renal tumors but also in synchronous VHL-related lesions, especially pancreatic solid nodules whose exact nature (metastatic RCC or neuroendocrine tumor) cannot be ruled out without invasive biopsy.

CEUS increases the diagnostic accuracy of US in the differential diagnosis of benign and malignant LNs but it also allows us, when possible, to avoid unnecessary invasive operations such as LN FNAC. Moreover, CEUS may guide FNAC in the case of focal cortical thickening on the basis of hypoperfusion, with a reduction in the number of false negatives and much earlier detection of nodal metastatic foci.

Purpose The purpose of this study was to evaluate the usefulness of contrast-enhanced ultrasonography (CEUS) in the bioptic sampling of soft tissue tumors (STT) compared with unenhanced ultrasonography alone. Methods This is a prospective longitudinal study of 40 patients subjected to ultrasonography (US)-guided core needle biopsy (CNB) to characterize a suspected STT. Three series of bioptic samplings were carried out on each patient, respectively using unenhanced US alone and CEUS in both the areas of the tumor enhanced or not by the contrast medium. All bioptic samples underwent a histological evaluation and the results were analyzed by comparing the histology of the biopsy with the definitive diagnosis in 15 surgically excised samples. Results 27 (67.5 %) of the 40 patients completed the entire study procedure; in 19 cases (70.3 %) the three bioptic samplings gave unanimous results, also when compared to the surgical specimen; in seven cases (25.9 %) use of CEUS allowed to obtain additional or more accurate information about the mass in question, compared to simple US guidance without contrast; in one patient (3.7 %) sampling obtained using unenhanced ultrasonography guidance and in the areas enhanced by the contrast agent had precisely the same results of the surgical specimen. Conclusions CEUS, due to its ability to evaluate microvascular areas, has proven to be a promising method in guiding bioptic sampling of soft tissue tumor, directing the needle to the most significant areas of the tumor. Given the small number of patients evaluated in our study, to achieve statistically significant results, it would be appropriate to obtain a larger sample size, since the very first results seem to be encouraging and to justify the increase of the population.Keywords Contrast-enhanced ultrasonography Á Soft tissue tumors Á Core needle biopsy Riassunto Scopo Lo scopo di questo studio è stato quello di valutare l'utilità dell'ecografia conmdc (CEUS) rispetto alla ecografia tradizionale, nel prelievo bioptico dei tumori dei tessuti molli (STT). Metodi si tratta di uno studio longitudinale prospettico di 40 pazienti sottoposti ad ago-biopsia ecoguidata (US-CNB) per la caratterizzazione di un STT sospetto. Sono stati prelevati 3 campioni bioptici su ogni paziente, utilizzando ecografia b-mode e CEUS sia nelle aree del tumore non evidenziate dal mezzo di contrasto che in quelle dotate di contrast-enhancement. Tutti i campioni bioptici sono stati sottoposti a valutazione istologica e sono stati analizzati i risultati confrontando l'istologico della biopsia con i 15 campioni asportati chirurgicamente, con diagnosi definitiva. (2015( ) 18:335-342 DOI 10.1007 Risultati 27 (67,5%) dei 40 pazienti hanno completato l'intera procedura di studio; in 19 casi (70,3%) i tre campioni bioptici hanno dato risultati unanimi, anche rispetto al modello chirurgico; in 7 casi (25,9%) l'uso della CEUS ha permesso di ottenere informazioni supplementari, o più precise, circa la massa in questione, rispetto al semplice esame ecografico ...

Merkel Cell Carcinoma (MCC) is a highly aggressive neuroendocrine neoplasm of the skin. Due to its rarity, the management of MCC is not standardized across centers. In this article, we present the experience of the Veneto region in the NorthEast of Italy, where a committee of skin cancer experts has proposed a clinical pathway for the diagnosis and treatment of MCC. Putting together the evidence available in the international literature, we outlined the best approach to the management of patients affected with this malignancy step-by-step for each possible clinical situation. Crucial in this pathway is the role of the multidisciplinary team to deal with the lack of robust information on each aspect of the management of this disease.
