Abstract
PURPOSE To compare magnetic resonance imaging (MRI) findings with gadoxetic acid and gadobenate dimeglumine for the diagnosis of hepatic hemangiomas. MATERIALS AND METHODS In this retrospective study, we included 26 hemangiomas (mean size was 14 mm ± 10 mm) in 19 patients (mean age 60 ± 14 years) scanned with both gadobenate dimeglumine MRI and gadoxetic acid MRI. For each patient, we collected multiple lesion variables including location, number, size and enhancement pattern on arterial, portal venous, 3-minute and hepatobiliary phases with both gadoxetic acid and gadobenate dimeglumine. The enhancement pattern with the two contrast agents was then compared. RESULTS The typical enhancement pattern of hepatic hemangiomas was more common-though not statistically significant-with gadobenate dimeglumine compared to gadoxetic acid (57% [15 of 26] vs 42% [11 of 26], respectively; P = 0.4057 for both peripheral globular discontinuous enhancement in the arterial phase and centripetal fill-in in the portal venous phase). A significantly higher number of hemangiomas showed centripetal fill-in or hyperintensity in the 3-minute phase with gadobenate dimeglumine compared to gadoxetic acid (88% [23 of 26) vs 58% [15 of 26]; P = 0.0266). A pseudo washout sign in the 3-minute phase was detected in one of the 5 flash-filling hemangiomas with gadoxetic acid, but not gadobenate dimeglumine. All hemangiomas were hypointense in the hepatobiliary phase with both gadobenate dimeglumine and gadoxetic acid. CONCLUSIONS The enhancement pattern of hepatic hemangiomas may vary depending on the hepatobiliary agent, with more frequent lack of the typical pattern with gadoxetic acid compared to gadobenate dimeglumine.

Abstract
PURPOSE Thyroidectomy is the preferred approach as the definitive treatment for Graves' disease. The outcomes for total thyroidectomy in a large series of 594 patients, who were observed in the last decade, will be presented in this study. METHODS The study concerned a retrospective review of 594 patients, undergoing a total thyroidectomy for Graves' disease. The incidence of complications and outcomes on hyperthyroidism and correlated symptoms resolution were also evaluated. RESULTS The mean age of the patients was of 44.7 ± 12.7 years and 456 patients (76.7%) were females. The mean gland weight was 67.3 ± 10.8 g (range: 20-350 g) and, in 397 patients (66.8%), the gland weighed >40 g. The mean operative time was 125 ± 23.1 min (range: 65-212 min). Temporary and permanent hypocalcaemia developed in 241 (40.6%) and 3 patients (0.5%), respectively. Temporary and permanent recurrent laryngeal nerve palsy were recorded in 31 (5.2%) and 1 patients (0.16%) respectively. No patient developed a thyroid storm. On multivariate analysis, patient age ≤50 years (Odds ratio: 1; 95% Confidence Interval: 0.843-0.901) and thyroid weight >40 g (Odds ratio: 1; 95%, Confidence Interval: 0.852-0.974), were mainly associated with the occurrence of complications. CONCLUSION This high-volume surgeon experience demonstrates that total thyroidectomy is a safe and effective treatment for Graves' disease. It is associated with a very low incidence rate of post-operative complications, most of which are transitory; therefore, it offers a rapid and definitive control of hyperthyroidism and its related symptoms.

Abstract
BACKGROUND The association between Hashimoto's thyroiditis (HT) and papillary thyroid carcinoma (PTC) is a controversial question that is still under debate, its pathological significance and the eventual clinical implications of this association remaining unclear. METHODS The data regarding 305 patients were retrospectively analyzed. The patients were divided in two different groups. A first group made up of 142 patients undergoing surgery for differentiated thyroid carcinoma was compared to a control group of 142 analogous subjects operated for normofunctioning goiter. A second group was made up of 163 patients who had undergone total thyroidectomy (TT) with pre-operative diagnosis of HT. RESULTS In the first group of patients an association with HT was found in 28,6% of the patients with final histopathological diagnosis of PTC versus 7,7% of the patients with histopathological diagnosis of multinodular goiter, which was a significant difference (p < 0.001). In the second group, the association with PTC was found in 43 (40,2%) cases of HT nodular variant and in 3 cases (8,1%) of HT diffuse variant (p < 0.001). CONCLUSIONS The relationship between HT and PTC is still far from clear and represents an unresolved issue. Our own study has underlined the frequent coexistence of these two pathologies, an aspect not to be neglected in clinical practice. Patients receiving HT diagnosis should undergo careful follow-up and, especially those with the nodular variant, should undergo a frequent both clinical and cytological evaluation of the nodular lesions, taking always into great consideration the surgical approach of total thyroidectomy.

Abstract
The purpose of this study is to verify whether the performance of ultrasound-guided quadrantectomy (USGQ) versus palpation-guided quadrantectomy (PGQ) can reduce the incidence of positive margins and if it can change the attitude of the surgeon. A retrospective study was conducted on 842 patients underwent quadrantectomy for breast cancer, 332 of them underwent USGQ, whereas 550 underwent PGQ. The histological type of the tumors and the margin status obtained with the histological examination were compared. The histological examination of the surgical specimen showed involvement of the margins in 24/842 patients (2.85%), 22 (2.61%) of them belonged to the PGQ group, and two to the USGQ group (P = 0.0011). The highest rate of microscopically positive margins was, statistically significant, for carcinoma in situ, when compared with patients with invasive carcinoma (0.0001). USGQ technique showed several advantages compared with PGQ. In fact, the former notes a lower positive margin rate and, consequently, a lower rate of reintervention. In addition, it may change the surgeon's attitude by causing him to remove another slice of margin to ensure more histological negativity. It should be the gold standard technique for breast-conservative surgery of palpable tumors.

Abstract
Aims and background Gastrointestinal stromal tumors (GISTs), although rare, are the most common mesenchymal neoplasms affecting the gastrointestinal tract. We present our experience in the treatment of localized and metastatic disease and a review of literature. Patients and methods Nine patients were observed from April 2002 to July 2004. Eight tumors were in the gastric area and J was in the small bowel. In 5 cases, complete surgical removal was performed, and none of these patients underwent adjuvant therapy. The remaining 4 cases, with locally advanced or recurrent disease, were treated with imatinib. Results The patients with localized disease treated only by surgery did not relapse. In the patients with locally advanced or metastatic disease treated by imatinib, we observed 3 partial responses, and one case was not assessable because he had no measurable disease. In 2 of 3 responders, it was possible to perform a new radical surgery. Conclusions Our series is too small to draw any conclusion. According to our review of the literature, surgery remains the standard treatment for non-metastatic GISTs. Imatinib mesylate represents a major breakthrough in the treatment of advanced GISTs and is the first effective systemic therapy for the disease.

Abstract
BACKGROUND The prognostic value of sentinel lymph node (SLN) micrometastases in invasive breast cancer patients is still widely debated. Even if, in the absence of unequivocal guidelines, the axillary lynphadenectomy is not still performed in the routine clinical care of these patients. MATERIALS AND METHOD We have retrospectively analyzed 897 patients with operable invasive breast cancer and clinically negative axillary lymph nodes underwent conservative surgery or total mastectomy with SLN biopsy. Two groups of patients with SLN micrometastases and isolated tumor cells (ITC) were considered, the first one treated with completion axillary dissection, the second one not followed by further surgical axillary procedure. The incidence of axillary recurrences has BEEN evaluated in both groups and only in the first group of patients the involvement of the remaining lymph nodes was analyzed. RESULTS Micrometastases were found in 67 (7.4%) patients and ITC in 8 (0,9%) patients. 14 (20.9%) patients with micrometastases and 1 (12.5%) patient with ITC underwent completion axillary dissection. 53 (79.1%) patients with micrometastases and 7 (87.5%) with ITC didn't receive further surgical axillary procedure. No axillary recurrences were found during a median follow up of 65.7±8.69 months in both groups of patients. CONCLUSIONS Based on the results and according to some recent randomized trials we can say that completion axillary dissection can be safely avoided when micrometastases are found in sentinel lymph nodes. It should be performed anyway, depending on the analysis of the biomedical profile of the tumor. KEY WORDS Breast Carcinoma, Micrometastases Axillary Lymphonode Dissection, Sentinel Lymphonode.

Abstract
γδ T cells usually infiltrate many different types of cancer, but it is unclear whether they inhibit or promote tumor progression. Moreover, properties of tumor-infiltrating γδ T cells and those in the corresponding normal tissue remain largely unknown. Here we have studied features of γδ T cells in colorectal cancer, normal colon tissue and peripheral blood, and correlated their levels with clinicopathologic hallmarks. Flow cytometry and transcriptome analyses showed that the tumor comprised a highly variable rate of TILs (5-90%) and 4% γδ T cells on average, with the majority expressing Vδ1. Most Vδ1 and Vδ2 T cells showed a predominant effector memory phenotype and had reduced production of IFN- γ which was likely due to yet unidentified inhibitory molecules present in cancer stem cell secretome. Transcriptome analyses revealed that patients containing abundant γδ T cells had significantly longer 5-year disease free survival rate, suggesting their efficacy in controlling tumor at very early stage.

Abstract
The tumor microenvironment supplies proinflammatory cytokines favoring a permissive milieu for cancer cell growth and invasive behavior. Here we show how breast cancer progression is facilitated by IL4 secreted by adipose tissue and estrogen receptor-positive and triple-negative breast cancer cell types. Blocking autocrine and paracrine IL4 signaling with the IL4Rα antagonist IL4DM compromised breast cancer cell proliferation, invasion, and tumor growth by downregulating MAPK pathway activity. IL4DM reduced numbers of CD44+/CD24- cancer stem-like cells and elevated expression of the dual specificity phosphatase DUSP4 by inhibiting NF-κB. Enforced expression of DUSP4 drove conversion of metastatic cells to nonmetastatic cells. Mechanistically, RNAi-mediated attenuation of DUSP4 activated the ERK and p38 MAPK pathways, increased stem-like properties, and spawned metastatic capacity. Targeting IL4 signaling sensitized breast cancer cells to anticancer therapy and strengthened immune responses by enhancing the number of IFNγ-positive CTLs. Our results showed the role of IL4 in promoting breast cancer aggressiveness and how its targeting may improve the efficacy of current therapies. Cancer Res; 77(12); 3268-79. ©2017 AACR.

Abstract
UNLABELLED Neuroendocrine carcinoma of the breast is an extremely rare tumor. A standard treatment has yet to be established because only a few cases have been reported in literature. The authors report five cases observed from January 2007 to December 2014 and a review of literature. Four patients underwent quadrantectomy and in two cases axillary nodal dissection and only one to mastectomy with axillary nodal dissection. Tumor size was from T1 to T2 with N0 to N1, according TNM classification. Pathological specimens were stained with hematoxylin and eosin and an immunohistochemical panel of antibodies (Neuron-specific enolase, Chromogranin, Synaptophysin, Estrogen and Progesterone receptors, c-erb and Ki-67). All cases showed markers positivity to Neuron-specific enolase, Chromogranin, Synaptophysin and Estrogen and Progesterone receptors were found. Ki-67 was higher than 40% in four patients. Adjuvant chemotherapy was administrated in patients with Ki-67>10%; every patients were treated with radiotherapy and with hormonal therapy too. Although Neuroendocrine breast tumor is considered a distinct entity, the best treatment seems to be correlate to the size of tumor and to the lymph node status and to Ki-67 index like the common breast cancer.

Abstract
Abstract
BACKGROUND:
Triple-negative breast cancers (TNBC) represent the 10-17% of all diagnosed breast cancers (BC) and are characterized by the absence of ER/PgR expression, HER2 amplification and often show a basal-like phenotype. TNBC are often diagnosed in patients with BRCA1 germline mutation and unfortunately treatment options are still limited. The mTOR (Mammalian Target Of Rapamycin) pathway seems to play an important role in BC pathogenesis and it is possible to target this pathway by inhibitors such as rapamycin. In human BC cross talk between ER/PgR receptors signaling and the mTOR pathway is believed to be responsible for resistance to hormone therapy probably due to a down regulation of hormone receptors. Based on these evidences we have hypothesized that the inhibitors of mTOR pathway may lead to the up-regulation of ER, PgR and HER2 in TNBC cell lines.
METHODS:
For this study we used TNBC cells (MDA-MB-231 and BT20) cultured in DMEM:F12 (Dulbecco's Modified Eagle's Medium) with 10% bovine serum (FBS), 100 U/mL penicillin (1%) and 50 mg/mL of streptomycin under standard conditions (37°C in an atmosphere composed of 16% O2, 79% N2 and 5% CO2).
Cells were initially treated with Rapamycin (1, 5, 10, 15 microM) for 24, 48, and 72h in order to verify if the drug determines a blockade of cell proliferation. Before drug administration, the cells were subjected to serum starvation by eliminating serum from culture medium. The evaluation of cell viability following the administration of the drug was carried out using the MTT assay. Real time PCR analyses were carried out in order to evaluate gene expression modifications of ER, PgR and HER2 receptors, through Taqman probe chemistry.
RESULTS:
The preliminary cell viability experiments conducted on different TNBC cell lines (MDA-MB-231 and BT20), showed no significant cytotoxic effects by increasing Rapamycin concentrations (1, 5 and 10 microM) after 72h treatment, except for the higher concentration (15 microM) for which a cytotoxic effect was observed.
The following qPCR approach highlighted significant variations in estrogen and progesterone receptor gene expression for the TNBC cell lines after 24, 48, 72h with 1, 5, 10 microM Rapamycin. In particular their expression level resulted up-regulated. Unlikely no association between mTOR inhibition and HER2 expression level were identified, suggesting no effects of mTOR inhibition on HER2 expression.
CONCLUSION AND FUTURE PERSPECTIVES:
To these preliminary results suggest that the mTOR inhibition leads to re-expression of hormone receptors. This finding supports a potential clinical application of mTOR inhibition in TNBC. The perspective of phenotype change upon rapamycin treatment prompts new therapeutic scenarios. However, further investigations are needed to explain the biological mechanisms driving these changes.

Abstract
Dietary restrictions, including fasting (or long-term starvation), calorie restriction (CR), and short-term starvation (STS), are considered a strong rationale that may protect against various diseases, including age-related diseases and cancer. Among dietary approaches, STS, in which food is not consumed during designed fasting periods but is typically not restricted during designated feeding periods, seems to be more suitable, because other dietary regimens involving prolonged fasting periods could worsen the health conditions of cancer patients, being they already naturally prone to weight loss. Until now, the limited amount of available data does not point to a single gene, pathway, or molecular mechanism underlying the benefits to the different dietary approaches. It is well known that the healthy effect is mediated in part by the reduction of nutrient-related pathways. The calorie restriction and starvation (long- and short-term) also suppress the inflammatory response reducing the expression, for example, of IL-10 and TNF-α, mitigating pro-inflammatory gene expression and increasing anti-inflammatory gene expression. The dietary restriction may regulate both genes involved in cellular proliferation and factors associated to apoptosis in normal and cancer cells. Finally, dietary restriction is an important tool that may influence the response to chemotherapy in preclinical models. However, further data are needed to correlate dietary approaches with chemotherapeutic treatments in human models. The aim of this review is to discuss the effects of various dietary approaches on the cancer progression and therapy response, mainly in preclinical models, describing some signaling pathways involved in these processes.

Abstract
UNLABELLED represents a safe and complete technique to remove benign lesions of the rectum not treatable by endoscopy and malignant rectal lesions at early stage. It is a valid alternative to transanal endoscopic microsurgery (TEM), to conventional transanal surgery and to transabdominal resection. METHODS In our operating Unit we performed a resection of 8 voluminous adenoma in the rectal ampulla with SILSTM-Port. RESULTS The mean age of the patients was of 51.1 years, the mean BMI was 23. There were not intra or post-operative complications nor conversions to conventional transanal excision or major resective surgery. The postoperative course was normal. The average time of hospitalization was 3 days. CONCLUSIONS TEVA is easier to perform than TEM and does not require a long training and specific and expensive material as the TEM does. TEVA might go to replace completely TEM. KEY WORDS Rectal tumours, SILS, TEVA.

Abstract
AIM The prognostic value of sentinel lymph node micrometastases in invasive breast cancer patients is still widely debated. Even if, in the absence of unequivocal guidelines, the axillary lynphadenectomy is not still performed in the routine clinical care of these patients. METHOD We have retrospectively analyzed 746 patients with operable invasive breast cancer and clinically negative axillary lymph nodes. These patients underwent conservative surgery or total mastectomy with sentinel lymph node biopsy. Patients with micrometastases in the sentinel lymph node treated with axillary dissection has been checked and the involvement of the remaining lymph nodes analyzed. Patients with micrometastases in the SLN not followed by axillary dissection have been checked as well and the incidence of recurrences has been evaluated in both groups. RESULTS Micrometastases were found in 51 (6.83%) patients and isolated tumor cells in 8 (1.07%) patients at frozen section and confirmed at the final hystopathologic examination. Fifteen of these patients underwent complete axillary dissection: two of them (13.33%) had metastatic involvement of other axillary lymph nodes. The other 44 patients didn't receive further surgical axillary procedure. No axillary recurrences in these patients were found during a median follow up of 65.3±9.65 months (range 42-78 months). CONCLUSION Based on the results and according to some recent randomized trials we can say that axillary lynphadenectomy can be avoided when micrometastases are found in sentinel lynph nodes. It should be performed anyway, depending on the analysis of the biomedical profile of the tumor. KEY WORDS Breast carcinoma, Micrometases, Sentinel lymph node.

Abstract
BACKGROUND Recently, attention has been focused on physicians' stress and quality-of-life improvement. Due to their relationship with patients, oncologists in particular are overloaded physically, emotionally and psychologically. Previous studies showed that training of communication skills improves the satisfaction and well-being of physicians and patients. AIMS Our research investigates the relationship between work stress and engagement and personal well-being in physicians working in Italian hospitals. MATERIALS AND METHODS 176 physicians were included. Doctors filled out self-report questionnaires to evaluate work stress and coping strategies, personal well-being, work engagement and two purpose-built scales to measure the degree of perceived organizational support and the level of specific training of social and relational skills. Descriptive statistics were used to analyze data, as well as correlation analysis (Pearson's r), hierarchical regression analysis (enter step) and analysis of variance (one-way ANOVA). RESULT Positive and significant correlations were found between variables. Moreover, physicians who obtained higher levels of specific training on social and relational skills reported lower levels of stress. Oncologists experienced greater stress than other physicians in terms of maladaptive coping and lack of additional training. CONCLUSIONS The study suggests that physicians' well-being is mediated by professional aspects, such as social skills in relationships with patients.

Abstract
BACKGROUND Seroma formation frequently occurs in patients who have undergone axillary lymphadenectomy. The aim of the study was to evaluate the effect of fibrin glue in the prevention of seroma formation after axillary lymphadenectomy. MATERIALS AND METHODS Hundred fifty-nine breast cancer patients about to undergo quadrantectomy or mastectomy plus axillary lymphadenectomy were enrolled in the study and randomized into two groups. Fibrin glue spray applied to the axillary fossa plus placement of closed suction drainage were used in 80 patients (group A); placement of closed suction drainage was only used in 79 patients (group B). RESULTS Group A patients showed a slight advantage with regard to the mean duration of axillary drainage placement (4.5 +/- 1.3 days in group A vs. 5.1 +/- 1.6 days in group B) and number of seroma aspirations (6.3 +/- 1.1 in group A vs. 6.7 +/- 1.2 in group B). No statistically significant differences were observed between the two groups of patients regarding the mean volume of total axillary drainage and of total seroma volume. CONCLUSIONS The use of fibrin glue does not prevent seroma formation and does not reduce seroma magnitude and duration. The costs of the product involved do not justify its routine use in patients undergoing axillary dissection.

Abstract
BACKGROUND Although Ki-ras and TP53 mutations have probably been the genetic abnormalities most exhaustively implicated and studied in colorectal cancer (CRC) progression, their significance in terms of disease relapse and overall survival has not yet clearly been established. PATIENTS AND METHODS A prospective study was carried out on paired tumor and normal colon tissue samples from a consecutive series of 160 previously-untreated patients, undergoing resective surgery for primary operable sporadic CRC. Mutations within the TP53 (exons 5-8) and Ki-ras (exon 2) genes were detected by PCR-SSCP analyses following sequencing. RESULTS Mutation analyses of exons 5 to 8 of the TP53 gene showed mutations in 43% (68/160) of the cases, while mutation analyses of exon 2 of the Ki-ras gene showed mutations in 46% (74/160) of the cases. Multivariate analyses showed that clinical outcome were strongly associated with the presence of specific TP53 mutations in L3 domain alone (only in DFS) or in combination with specific Ki-ras mutations at codon 13. CONCLUSION Specific TP53 mutations in L3 domain alone (only in DFS) or in combination with specific Ki-ras mutations at codon 13 are associated with a worse prognosis in sporadic CRC.

Abstract
BACKGROUND Secretory mammary carcinoma is a rare breast neoplasia originally described in children but sometimes also found in adults. It presents a more favourable outcome than more common histological types of breast carcinoma; published literature in fact reports only a few cases with axillary lymph node metastases and only four cases with distant metastases. CLINICAL PRESENTATION In this paper we report a rare case of secretory breast carcinoma with axillary lymph node metastases in a 33-year-old woman. To our knowledge, this is the first case of secretory carcinoma involving biopsy of the sentinel lymph node and investigation of the e-cadherin expression. We found positivity for e-cadherin, which would support the hypothesis that this type of tumour is a variant of the infiltrating ductal carcinoma. CONCLUSION After a careful analysis of reported data, we have come to the conclusion that the treatment of choice for patients with secretory breast carcinoma should be conservative surgery with sentinel lymph node biopsy, followed by accurate follow-up. We are of the opinion that while post-operative radiotherapy is indicated in adult patients who have undergone quadrantectomy, it should not be used in children. Although several cases of secretory carcinoma have been treated with adjuvant chemotherapy, there are still no reliable data regarding the real value of such a choice.

Abstract
To prospectively evaluate the prognostic significance of TP53, H-, K-, and N-Ras mutations, DNA-ploidy and S-phase fraction (SPF) in patients affected by locally advanced laryngeal squamous cell carcinoma (LSCC). Eight-one patients (median follow-up was 71 months) who underwent resective surgery for primary operable locally advanced LSCC were analyzed. Tumor DNA was screened for mutational analysis by PCR/SSCP and sequencing. DNA-ploidy and SPF were performed by flow cytometric analyses. Thirty-six patients (44%) had, at least, a mutation in the TP53 gene. Of them, 22% (8/36) had double mutations and 3% (1/36) had triple mutations. In total, 46 TP53 mutations were observed. The majority (41%) of these occur in exon 5 (19/46), while the mutations in exons 6, 7, and 8 were represented in 14, 7, and 6 patients, respectively (31%, 15%, and 16%). Five LSCC patients (6%) showed a mutation in H-Ras gene. Sixty-three percent of the cases (51/81) were DNA aneuploidy, 14% of these (7/51) were multiclonal. Thirty-nine patients (48%) had an high SPF value. At Univariate analysis, the DNA aneuploidy, high SPF (>15.1%), TP53 mutations and, in particular, the mutations that occur in exons 5 and 8 were significantly related to quicker disease relapse and short OS. At Multivariate analysis, the major significant predictors for both disease relapse and death were high SPF and any TP53 mutations. While histological grade G3 was an independent factor only for relapse. In conclusions, any TP53 mutations and high SPF are important biological indicators to predict the outcome of LSCC patients.
