Background: Few data are available on the benefit of metronomic cyclophosphamide, capecitabine, and vinorelbine as first-line therapy in patients with metastatic triple-negative breast cancer. Methods: This phase II study assessed the safety and efficacy of metronomic oral chemotherapy with vinorelbine 40 mg orally 3 times a week, cyclophosphamide 50 mg daily, and capecitabine 500 mg 3 times a day (VEX regimen) in untreated metastatic triple-negative breast cancer patients. The biopsy of the metastatic site had to be triple-negative, independent of the hormone receptor expression of the primary tumor. The primary endpoint was time to progression (TTP). Secondary endpoints included assessment of safety and clinical benefit (objective response rate plus stable disease rate at ≥24 weeks). Results: 25 patients were included, and 22 were evaluable for both efficacy and toxicities (median age, 66 years). Median TTP was 6.4 months (95% confidence interval 3.6-12.6). The most common grade 1-2 toxicities were nausea, diarrhea, leuko-/neutropenia, and reversible liver enzyme alteration. Grade 3 events included hand and foot syndrome (9%). Conclusion: The VEX regimen demonstrated activity and was relatively well tolerated when given as first-line therapy in selected metastatic breast cancer patients with triple-negative disease

Aim: Cigarette smoking is an established risk factor for pancreatic cancer but an updated quantification of the association is lacking. Our aim is to provide the most accurate and updated estimate of the dose–response relationships between cigarette smoking and pancreatic cancer risk. Methods: Using an innovative approach for the identification of original publications, we conducted a systematic review and meta-analysis of epidemiological studies published on the issue up to April 2017. Random effects models were used to provide pooled estimates for the cigarette smoking status; dose–risk relationships were evaluated using one-stage random effects models with restricted cubic splines. Results: Seventy-eight studies were included, providing a pooled relative risk (RR) of pancreatic cancer of 1.8 (95% confidence interval, CI: 1.7–1.9) for the current and 1.2 (95% CI: 1.1–1.2) for the former vs. never smokers. A sharp increase in pancreatic cancer risk was found already with a low number of cigarettes and up to 30 cigarettes/day (RR 2.2, 95% CI: 1.9–2.4). Similarly, the risk of pancreatic cancer steady increased after a few years of smoking up to 30 years (RR 1.8, 95% CI: 1.6–2.0). The risk rapidly decreased with increasing time since quitting and was 0.6 (95% CI: 0.5–0.7, for the former vs. current smokers) after 20 years of quitting. Conclusions: The present meta-analysis indicates that pancreatic cancer risk sharply increases with a low number of cigarettes or after a few years of smoking and that it rapidly decreases a few years after cessation, although it takes almost 20 years to reach that of never smokers.

Inflammatory breast cancer is a rare and highly aggressive disease. We investigated in a phase II study a neoadjuvant regimen with chemotherapy and an antiangiogenic strategy. The pathologic complete remission (pCR) rate was 29% and was significantly greater in patients with HER2 + tumors (57%). The achievement of a pCR was associated with longer disease-free and overall survival. The investigated regimen was effective and well tolerated. The antiangiogenic strategy warrants further studies in this setting. Background: Inflammatory breast cancer (IBC) is a rare and highly aggressive disease. A neoadjuvant regimen with chemotherapy and an antiangiogenic strategy was investigated. Patients and Methods: Patients with primary or recurrent IBC who were candidates for neoadjuvant treatment received weekly carboplatin and paclitaxel plus bevacizumab every 3 weeks and oral metronomic cyclophosphamide for 6 months. Trastuzumab was added for patients with HER2 + tumors and endocrine therapy was added for patients with estrogen receptor and/or progesterone receptor ≥ 10% tumors. Oral metronomic capecitabine and cyclophosphamide was continued for 6 months after surgery in those patients with a response. The primary efficacy endpoints were pathologic complete remission (pCR) and the objective response. Results: From July 2010 to December 2013, 34 patients with IBC were included. The surrogate intrinsic tumor subtypes were as follows: luminal B-like (HER2 − ), 10 (29%); luminal B-like (HER2 + ), 8 (24%); HER2 + (nonluminal), 6 (18%); and triple negative, 10 (29%). An objective response was obtained in 30 patients (88%; 95% confidence interval, 73%-97%) and a pCR in 10 patients (29%; 95% confidence interval, 15%-48%). The proportion of pCR was significantly greater in the patients with HER2 + tumors (57%) than in patients with triple-negative (20%) or luminal B-like (HER2 − ) tumors (0%; P =.019). After a median follow-up of 4.4 years, the 5-year disease-free survival and overall

Donation after circulatory death (DCD) in Italy constitutes a relatively unique population because of the requirement of a no-touch period of 20 minutes. The first aim of this study was to compare liver transplantations from donors who were maintained on normothermic regional perfusion after circulatory death and suffered extended warm ischemia (DCD group, n = 20) with those from donors who were maintained on extracorporeal membrane oxygenation (ECMO) and succumbed to brain death (ECMO group, n = 17) and those from standard donors after brain death (donation after brain death [DBD] group, n = 52). Second, we conducted an explorative analysis on the DCD group to identify relationships between the donor characteristics and the transplant outcomes. The 1-year patient survival for the DCD group (95%) was not significantly different from that of the ECMO group (87%; P = 0.47) or the DBD group (94%; P = 0.94). Graft survival was slightly inferior in the DCD group (85%) because of a high rate of primary nonfunction (10%) and retransplantation (15%) but was not significantly different from the ECMO group (87%; P = 0.76) or the DBD group (91%; P = 0.20). Although ischemic cholangiopathy was more frequent in the DCD group (10%), this issue did not adversely impact graft survival because none of the recipients underwent retransplantation due to biliary complications. Moreover, the DCD recipients were more likely to develop posttransplant renal dysfunction with the need for renal replacement therapy. Further analysis of the DCD group showed that warm ischemia >125 minutes and an Ishak fibrosis score of 1 at liver biopsy negatively impacted serum creatinine and alanine transaminase levels in the first posttransplant week, respectively. In conclusion, our findings encourage the use of liver grafts from DCD donors maintained by regional perfusion after proper selection.

Background: Despite the acknowledged sex-related dimorphism in immune system response, little is known about the effect of patients' sex on the efficacy of immune checkpoint inhibitors as cancer treatments. We did a systematic review and meta-analysis to assess the heterogeneity of immune checkpoint inhibitor efficacy between men and women. Methods: We systematically searched PubMed, MEDLINE, Embase, and Scopus, from database inception to Nov 30, 2017, for randomised controlled trials of immune checkpoint inhibitors (inhibitors of PD-1, CTLA-4, or both) that had available hazard ratios (HRs) for death according to patients' sex. We also reviewed abstracts and presentations from all major conference proceedings. We excluded non-randomised trials and considered only papers published in English. The primary endpoint was to assess the difference in efficacy of immune checkpoint inhibitors between men and women, measured in terms of the difference in overall survival log(HR) reported in male and female study participants. We calculated the pooled overall survival HR and 95% CI in men and women using a random-effects model, and assessed the heterogeneity between the two estimates using an interaction test. Findings: Of 7133 studies identified in our search, there were 20 eligible randomised controlled trials of immune checkpoint inhibitors (ipilimumab, tremelimumab, nivolumab, or pembrolizumab) that reported overall survival according to patients' sex. Overall, 11 351 patients with advanced or metastatic cancers (7646 [67%] men and 3705 [33%] women) were included in the analysis; the most common types of cancer were melanoma (3632 [32%]) and non-small-cell lung cancer (3482 [31%]). The pooled overall survival HR was 0·72 (95% CI 0·65–0·79) in male patients treated with immune checkpoint inhibitors, compared with men treated in control groups. In women treated with immune checkpoint inhibitors, the pooled overall survival HR compared with control groups was 0·86 (95% CI 0·

Background: Laparoscopic liver resection (LLR) has gained significant popularity over the last 10 years. First experiences of LLR compared to open liver resection (OLR) reported a similar survival and a better safety profile for LLR. Materials and methods: This is a retrospective analysis of prospectively collected data of all consecutive patients treated by liver resection for HCC on liver cirrhosis between January 2005 and March 2017. The choice of procedure (LLR vs OLR) was generally based on tumor localization, history of previous upper abdominal surgery and patient's preference. The type of resection and indication for surgery were unrelated to the adopted technique. Based on pre-operative variables and confirmed cirrhosis, a 1:1 propensity score matching (PSM) model was developed to compare outcomes of LLR and OLR in patients with HCC. Outcomes of interest included morbidity, mortality and long-term cure potential. Results: After-PSM, the LLR group demonstrated better perioperative results including: lower complication rate (50.7% in OLR vs 29.3% in LLR, p = 0.0035), significantly lower intra-operative blood loss (200 ml in OLR vs 150 ml in LLR, p = 0.007) and shorter hospital length of stay (median 9 days in OLR vs 7 days in LLR, p = 0.0018). Moreover there was no significant difference between the two groups in 3-year survival (76%, CI: 60%–86% in LLR vs 68%, CI: 55%–79% in OLR, p = 0.32) or recurrence-free survival rates (44%, CI: 28%–58%, vs 44%, CI: 31%–57%, p = 0.94). Conclusions: Minor LLR appeared significantly safer compared to minor OLR for HCC. LLR was associated with fewer post-operative complication, lower operative blood loss and a shorter hospital stay along with similar survival and recurrence-free survival rates

Background: Nipple-sparing mastectomy (NSM) is increasingly used in women with breast cancer who are not eligible for conservative surgery, but extensive outcome data are lacking and indications have not been established. Objective: The aim of this study was to assess the oncological outcomes of NSM in a large series of patients with invasive or in situ breast cancer treated at a single center. Methods: We analyzed 1989 consecutive women who had an NSM in 2003–2011, for invasive (1711 patients) or in situ cancer (278 patients) at the European Institute of Oncology, Italy, and followed-up to December 2016. Endpoints were local recurrences, recurrences in the nipple-areola complex (NAC), NAC necrosis, and overall survival (OS). Results: After a median follow-up of 94 months (interquartile range 70–117), 91/1711 (5.3%) patients with invasive cancer had local recurrence (4.8% invasive disease, 0.5% in situ disease), and 11/278 (4.0%) patients with in situ disease had local recurrence (1.8% invasive disease, 2.2% in situ disease). Thirty-six (1.8%) patients had NAC recurrence, 9 with in situ disease (4 invasive and 5 in situ recurrences), and 27 with invasive disease (18 invasive and 9 in situ recurrences). NAC loss for necrosis occurred in 66 (3.3%) patients. There were 131 (6.6%) deaths, 109 (5.5%) as a result of breast cancer. OS at 5 years was 96.1% in women with invasive cancer and 99.2% in women with in situ disease. Conclusions: The findings in this large series, with a median follow-up of nearly 8 years, indicate that NSM is oncologically safe for selected patients. The rate of NAC loss was acceptably low.

Background: Long QT syndrome (LQTS) is a common inheritable arrhythmogenic disorder, often secondary to mutations in the KCNQ1, KCNH2, and SCN5A genes. The disease is characterized by a prolonged ventricular repolarization (QTc interval) that confers susceptibility to life-threatening arrhythmic events (LAEs). Objectives: This study sought to create an evidence-based risk stratification scheme to personalize the quantification of the arrhythmic risk in patients with LQTS. Methods: Data from 1,710 patients with LQTS followed up for a median of 7.1 years (interquartile range [IQR]: 2.7 to 13.4 years) were analyzed to estimate the 5-year risk of LAEs based on QTc duration and genotype and to assess the antiarrhythmic efficacy of beta-blockers. Results: The relationship between QTc duration and risk of events was investigated by comparison of linear and cubic spline models, and the linear model provided the best fit. The 5-year risk of LAEs while patients were off therapy was then calculated in a multivariable Cox model with QTc and genotype considered as independent factors. The estimated risk of LAEs increased by 15% for every 10-ms increment of QTc duration for all genotypes. Intergenotype comparison showed that the risk for patients with LQT2 and LTQ3 increased by 130% and 157% at any QTc duration versus patients with LQT1. Analysis of response to beta-blockers showed that only nadolol reduced the arrhythmic risk in all genotypes significantly compared with no therapy (hazard ratio: 0.38; 95% confidence interval: 0.15 to 0.93; p = 0.03). Conclusions: The study provides an estimator of risk of LAEs in LQTS that allows a granular estimate of 5-year arrhythmic risk and demonstrate the superiority of nadolol in reducing the risk of LAEs in LQTS

Background: Joinpoint regression analysis is usually applied to study varying trends over time in order to identify the time point(s) in which the trend significantly changes. We illustrate three epidemiological investigations in which this methodology was applied with time-on-study as time-scale. Methods: Data were retrieved from the healthcare utilization databases of Lombardy Region (Italy). We investigated the trend of the: (1) mortality rate among centenarians hospitalized for hip fracture (2004-2011); (2) proportion of persistent patients after the initial prescription of antihypertensive drugs during the first year of treatment according to gender (2005); (3) prescription rate of statins in the year before and after the hospital admission among patients hospitalized for a transient ischemic attack (2008-2009). Results: The following results were obtained: (1) a joinpoint was identified in the fourth month, showing an increased risk of death during the three months after hip fracture hospitalization; (2) the proportion of patients still under antihypertensive treatment falls until the fifth month, remaining stable afterwards; there was evidence that the prevalence of patients who discontinued the treatment was significantly higher among women than men; (3) during the year after the transient ischemic attack episode, monthly rate of available statins was double than the previous year with a significant decrease in the first four months. Conclusions: The joinpoint regression analysis can be a useful tool in epidemiologic framework when a temporal trend is the objective of the investigation since it allows to make inference by means of a quantitative method rather than a qualitative evaluation.

Objectives With the present study, we aimed to investigate the association between menopausal hormone therapy (HT) and risk of colorectal cancer (CRC). Setting Cohort study based on the linkage of Norwegian population-based registries. Participants We selected 466822 Norwegian women, aged 55-79, alive and residing in Norway as of 1 January 2004, and we followed them from 2004 to 2008. Each woman contributed person-years at risk as non-user, current user and/or past HT user. Outcome measures The outcome of interest was adenocarcinoma of the colorectal tract, overall, by anatomic site and stage at diagnosis. Incidence rate ratios (RRs) with 95% CIs were estimated by Poisson regression and were used to evaluate the association between HT and CRC incidence. Results During the median follow-up of 4.8 years, 138 655 (30%) women received HT and 3799 (0.8%) incident CRCs occurred. Current, but not past, use of HT was associated with a lower risk of CRC (RR 0.88; 95% CI 0.80 to 0.98). RRs for localised, regionally advanced and metastatic CRC were 1.13 (95% CI 0.91 to 1.41), 0.81 (95% CI 0.70 to 0.94) and 0.79 (95% CI 0.62 to 1.00), respectively. RRs for current use of oestrogen therapy (ET) were 0.91 (95% CI 0.80 to 1.04) while RR for current use of combined oestrogen-progestin therapy (EPT) was 0.85 (95% CI 0.70 to 1.03), as compared with no use of HT. The same figures for ET and EPT in oral formulations were 0.83 (95% CI 0.68 to 1.03) and 0.86 (95% CI 0.71 to 1.05), respectively. Conclusions In our nationwide cohort study, HT use lowered the risk of CRC, specifically the most advanced CRC.

Background Short QT syndrome (SQTS) is a rare and life-threatening arrhythmogenic syndrome characterized by abbreviated repolarization. Hydroquinidine (HQ) prolongs the QT interval in SQTS patients, although whether it reduces cardiac events is currently unknown. Objectives This study investigated whether long-term treatment with HQ reduces the occurrence of life-threatening arrhythmic events (LAE) (cardiac arrest or sudden cardiac death) in SQTS patients. Methods In this cohort study on consecutive SQTS patients, 2 analyses were performed: 1) a matched-period analysis for the occurrence of LAE in 17 SQTS patients who received long-term HQ; and 2) a comparison of the annual incidence of LAE off- and on-HQ in 16 SQTS patients who survived a cardiac arrest. Results A total of 17 patients (82% male, age 29 ± 3 years, QTc before treatment 331 ± 3 ms) received HQ therapy (584 ± 53 mg/day). Therapy was stopped in 2 cases (12%) due to gastrointestinal intolerance, and 15 patients continued treatment for 6 ± 1 year. QTc prolongation was observed in all patients (by 60 ± 6 ms; p < 0.001). We compared the occurrence of LAE during 6 ± 1 years before and after HQ, observing that patients on HQ experienced a reduction in both the rate of LAE from 40% to 0% (p = 0.03) and the number of LAE per patient from 0.73 ± 0.3 to 0 (p = 0.026). Furthermore, the annual rate of LAE in the 16 patients with a previous cardiac arrest dropped from 12% before HQ to 0 on therapy (p = 0.028). Conclusions We demonstrated for the first time that treatment with HQ was associated with a lower incidence of LAE in SQTS patients. These data point to the importance that quinidine, that in several countries has been removed from the market, remains available worldwide for patients with SQTS. In the present study, therapy with HQ has been proven to be safe, with a relatively low rate of side effects.

INTRODUCTION: The aim of this study was to evaluate durability of Mitroflow and patterns of use compared with other aortic valves through a systematic review of the literature. EVIDENCE ACQUISITION: A total of 52 papers that included 33,630 patients met eligibility requirements that allowed summary statistical information to be determined regarding structural valve degeneration risk. EVIDENCE SYNTHESIS: Mitroflow has been disporportionately implanted in patients to be at higher risk for structural valve degeneration. CONCLUSIONS: Since Mitroflow valves were implanted more often in these high-risk patients, it was impossible to distinguish the effects of valve size or gender from valve type on structural valve degeneration risk.

Background: Tumor-infiltrating lymphocytes (TILs) are a robust prognostic adjunct in invasive breast cancer, but their clinical role in ductal carcinoma in situ (DCIS) has not been ascertained. Patients and methods: We evaluated the prevalence and clinical relevance of TILs in a well annotated series of 1488 consecutive DCIS women with a median follow-up of 8.2 years. Detailed criteria for TILs evaluation were pre-defined involving the International Immuno-Oncology Biomarker Working Group. TILs percentage was considered both as a continuous and categorical variable. Levels of TILs were examined for their associations with ipsilateral breast event (IBE), whether in situ or invasive. Results: Of the 1488 patients with DCIS under study, 35.1% had < 1%, 58.3% 1-49% and 6.5% ≥ 50% peri-ductal stromal lymphocytes. The interobserver agreement in TILs evaluation, measured by the intraclass correlation coefficient (ICC) was 0.96 (95% CI 0.95-0.97). At univariable analysis, clinical factors significantly associated with TILs (P ≥ 0.001) were intrinsic subtype, grade, necrosis, type of surgery. Her-2 positive DCIS were more frequently associated with TILs (24% of patients with TILs ≥ 50%), followed by the triple negative (11%), Luminal B/Her-2 positive (9%) and Luminal A/B subtypes (1%) (P < 0.0001). We did not find any association between TILs as a continuous variable and the risk of IBEs. Likewise, when patients were stratified by TILs percentage (<1%, between 1% and 49.9%, and ≥ 50%), no statistically significant association was observed (10- year cumulative incidence of IBEs: 19%, 17.3%, and 18.7% respectively, P = 0.767). Conclusion: TILs occur more frequently in the Her-2 positive DCIS. Although we did not find a significant association between TILs and the 10-year risk of IBE, our data suggest that immunotherapies might be considered in subsets of DCIS patients.

Objective: To investigate the association between long-term weight change and blood metabolites. Methods: Change in BMI over 8.6 ± 3.79 years was assessed in 3,176 females from the TwinsUK cohort (age range: 18.3-79.6, baseline BMI: 25.11 ± 4.35) measured for 280 metabolites at follow-up. Statistically significant metabolites (adjusting for covariates) were included in a multivariable least absolute shrinkage and selection operator (LASSO) model. Findings were replicated in the Cooperative Health Research in the Region of Augsburg (KORA) study (n = 1,760; age range: 25-70, baseline BMI: 27.72 ± 4.53). The study examined whether the metabolites identified could prospectively predict weight change in KORA and in the Prostate, Lung, Colorectal, and Ovarian Cancer (PLCO) study (n = 471; age range: 55-74, baseline BMI: 27.24 ± 5.37). Results: Thirty metabolites were significantly associated with change in BMI per year in TwinsUK using Bonferroni correction. Four were independently associated with weight change in the multivariable LASSO model and replicated in KORA: namely, urate (meta-analysis Î2 [95% CI] = 0.05 [0.040 to 0.063]; P = 1.37 × 10−19), gamma-glutamyl valine (Î2 [95% CI] = 0.06 [0.046 to 0.070]; P = 1.23 × 10−20), butyrylcarnitine (Î2 [95% CI] = 0.04 [0.028 to 0.051]; P = 6.72 × 10−12), and 3-phenylpropionate (Î2 [95% CI] = −0.03 [−0.041 to −0.019]; P = 9.8 × 10−8), all involved in oxidative stress. Higher levels of urate at baseline were associated with weight gain in KORA and PLCO. Conclusions: Metabolites linked to higher oxidative stress are associated with increased long-term weight gain.

Background The standard treatment for patients with small, node-negative, human epidermal growth factor receptor type 2 (HER2)–positive breast cancer (BC) is still controversial. Our aim was to assess the prognostic role of tumour-infiltrating lymphocytes (TILs) in patients with stage pT1a–b HER2-positive BC. Patients and methods Haematoxylin and eosin slides from node-negative, pT1a–b HER2-positive BC surgical specimens were retrieved from pathology archives to assess TILs and their association with outcome. Results TILs were evaluated in 205 patients with HER2-positive, pT1a–b tumours, who underwent breast surgery between 1997 and 2009 at the European Institute of Oncology. At a median follow-up of 11 years, we did not observe any association between the presence of TILs, either assessed as a continuous or dichotomous variable (<50 versus ≥ 50%), and outcome. Within the subgroup of patients with pT1a tumours who did not receive any adjuvant therapy (36/97 patients), the rate of disease-free survival events was lower in lymphocyte-predominant BC (LPBC) as compared with non-LPBC patients (p = 0.066). Conclusions TILs cannot be used as a prognostic biomarker in pT1a–b HER2-positive BC. Additional biomarkers are needed for selecting patients with stage I HER2-positive BC who candidate to adjuvant therapy de-escalation.

Background: Cancer-testis (CT) antigens, frequently expressed in human germline cells but not in somatic tissues, may become aberrantly reexpressed in different cancer types. The aim of this study was to investigate the expression of CT antigens in breast cancer. Patients and methods: A total of 100 selected invasive breast cancers, including 50 estrogen receptor (ER) positive/HER2 negative and 50 triple negative (TN), were examined for NY-ESO-1 and MAGE-A expression by immunohistochemistry. Results: A significantly higher expression of MAGE-A and NY-ESO-1 was detected in TN breast cancers compared with ER-positive tumors (P = 0.04). MAGE-A expression was detected in 13 (26%) TN cancers compared with 5 (10%) ER-positive tumors (P = 0.07). NY-ESO-1 expression was confirmed in nine (18%) TN tumor samples compared with two (4%) ER-positive tumors. Conclusions: MAGE-A and NY-ESO-1 CT antigens are expressed in a substantial proportion of TN breast cancers. Because of the limited therapeutic options for this group of patients, CT antigen-based vaccines might prove to be useful for patients with this phenotype of breast cancer

Our aim was to analyze the impact of a concurrent autoimmune disease on outcome of patients with early breast cancer. We reviewed medical charts of patients with a diagnosis of autoimmune diseases (AD) among a population of 17.153 cases. We categorized ADs as endocrine, rheumatic, systemic, neurological diseases and vasculitis. For each patient in the study group, we matched 2 patients. The events to determine overall survival (OS) and disease free survival (DFS) were identified from follow-up data. We identified 279 (1.62%) patients with early breast cancer and concurrent ADs. The median follow-up was 7.0 years. The 10-year OS rate was 86% (95% CI, 80% to 91%) in the study group and 90% (95% CI, 86% to 93%) for the control group (p = 0.011). In patients with ER positive/HER2 negative subtype a worse OS was observed in the study group when compared to the control group (p = 0.0046); this difference remained statistically significant when the analysis was restricted to breast cancer mortality (p = 0.045). The 10-year DFS rate was 69% (95% CI, 61% to 76%) in the study group and 72% (95% CI, 66% to 77%) for the control group (p = 0.22). Autoimmunity at diagnosis of early breast cancer is associated with worse survival.

Background Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a leading cause of sudden cardiac death, but its progression over time and predictors of arrhythmias are still being defined. Objectives This study sought to describe the clinical course of ARVC and occurrence of life-threatening arrhythmic events (LAE) and cardiovascular mortality; identify risk factors associated with increased LAE risk; and define the response to therapy. Methods We determined the clinical course of 301 consecutive patients with ARVC using the Kaplan-Meier method adjusted to avoid the bias of delayed entry. Predictors of LAE over 5.8 years of follow-up were determined with Cox multivariable analysis. Treatment efficacy was assessed comparing LAE rates during matched time intervals. Results A first LAE occurred in 1.5 per 100 person-years between birth and age 20 years, in 4.0 per 100 person-years between ages 21 and 40 years, and in 2.4 per 100 person-years between ages 41 and 60 years. Cumulative probability of a first LAE at follow-up was 14% at 5 years, 23% at 10 years, and 30% at 15 years. Higher risk of LAE was predicted by atrial fibrillation (hazard ratio [HR]: 4.38; p = 0.002), syncope (HR: 3.36; p < 0.001), participation in strenuous exercise after the diagnosis (HR: 2.98; p = 0.028), hemodynamically tolerated sustained monomorphic ventricular tachycardia (HR: 2.19; p = 0.023), and male sex (HR: 2.49; p = 0.012). No difference was observed in the occurrence of LAE before and after treatment with amiodarone, beta-blockers, sotalol, or ablation. A total of 81 patients received an implantable cardioverter-defibrillator, 34 were successfully defibrillated. Conclusions The high risk of life-threatening arrhythmias in patients with ARVC spans from adolescence to advanced age, reaching its peak between ages 21 and 40 years. Atrial fibrillation, syncope, participation in strenuous exercise after the diagnosis of ARVC, hemodynamically tolerated sustained monomorphic ventricular

The aim of this study was to evaluate the association between cancer occurrence and risk of graft failure in kidney transplant recipients. From November 1998 to November 2013, 672 adult patients received their first kidney transplant from a deceased donor and had a minimum follow-up of 6 months. During a median follow-up of 4.7 years (3523 patient-years), 47 patients developed a nonmelanoma skin cancer (NMSC) and 40 a noncutaneous malignancy (NCM). A total of 59 graft failures were observed. The failure rate was 6 per 100 patient-year (pt-yr) after NCM versus 1.5 per 100 pt-yr in patients without NCM. In a time-dependent multivariable model, the occurrence of NCM appeared to be associated with failure (HR = 3.27; 95% CI = 1.44–7.44). The effect of NCM on the cause-specific graft failure was different (P = 0.002) when considering events due to chronic rejection (HR = 0.55) versus other causes (HR = 15.59). The reduction of the immunosuppression after NCM was not associated with a greater risk of graft failure. In conclusion, our data suggest that post-transplant NCM may be a strong risk factor for graft failure, particularly for causes other than chronic rejection.

Background: Oncoplastic surgery is a well-established approach that combines conserving treatment for breast cancer and plastic surgery techniques. Although this approach has been described for T2 tumors, no long-term oncologic follow-up and no comparison with patients undergoing mastectomy has been published. The purpose of the study was to demonstrate that oncoplastic surgery is a safe and reliable treatment for managing invasive primary T2 breast cancer. Methods: We compared a consecutive series of 193 T2 patients who have undergone oncoplastic surgery (study group) with 386 T2 patients who have undergone mastectomy (control group). The endpoints evaluated were disease-free survival (DFS), overall survival (OS), cumulative incidence of local recurrence (CI-L), regional recurrence (CI-R), and distant recurrence (CI-D), all measured from the date of surgery. Results: Median follow-up is 7.4 years. The OS is similar within the two groups: 87.3 and 87.1 % at 10 years in the ONC group and control group, respectively (p value, adjusted for multifocality and tumor size, 0.74). Also, the DFS is similar in both groups: 60.9 and 56.3 % at 10 years in the ONC group and control group, respectively. The incidence of local events is slightly higher in the oncoplastic group, whereas the incidence of regional events is slightly higher in the mastectomy group. These differences are not statistically significant. The cumulative incidence of distant events is similar within the two groups. Conclusions: To our knowledge, the present study provides the best available evidence to suggest that oncoplastic approach is a safe and reliable treatment for managing invasive pT2 breast cancers.

Background Long QT syndrome type 3 (LQT3) is a lethal disease caused by gain-of-function mutations in the SCN5A gene, coding for the alpha-subunit of the sodium channel NaV1.5. Mexiletine is used to block late sodium current and to shorten QT interval in LQT3 patients. Objectives The aim of this study was to determine whether mexiletine prevents arrhythmic events (arrhythmic syncope, aborted cardiac arrest, or sudden cardiac death) in LQT3 patients. Methods The endpoint of this retrospective cohort study, which studied consecutive LQT3 patients who were referred to our center and treated with mexiletine, was to evaluate the antiarrhythmic efficacy of mexiletine by comparing the number of arrhythmic events per patient and the annual rate of arrhythmic events during observation periods of equal duration before and after the beginning of therapy with mexiletine. Results The study population comprised 34 LQT3 patients, 19 (56%) of whom were male. The median age at beginning of treatment with mexiletine was 22 years, and median QTc interval before therapy 509 ms. The median duration of oral mexiletine therapy was 36 months, at an average daily dose of 8 ± 0.5 mg/kg. Mexiletine significantly shortened QTc (by 63 ± 6 ms; p < 0.0001) and reduced the percentage of patients with arrhythmic events (from 22% to 3%; p = 0.031), the mean number of arrhythmic events per patient (from 0.43 ± 0.17 to 0.03 ± 0.03; p = 0.027), and the annual rate of arrhythmic events (from 10.3% to 0.7%; p = 0.0097). Conclusions Besides shortening QTc interval, mexiletine caused a major reduction of life-threatening arrhythmic events in LQT3 patients, thus representing an efficacious therapeutic strategy.

Aim: The primary aim of the study was to assess the association between risk of recurrence and HER2 equivocal gene status through immunohistochemistry in patients with early breast cancer. Patients and Methods: We retrospectively analyzed clinical and pathological data of 455 consecutive patients with early breast cancer (BC) who were HER2+ and had a HER2/CEP17 ratio <2.0, who underwent surgery at the European Institute of Oncology after 2007. The role of HER2/CEP17 ratio on recurrencefree survival was assessed with univariate and multivariate Cox regression models. Results: We found no significant association between risk of recurrence and HER2 equivocal testing in patients with early breast cancer. In subgroup analysis, a significant interaction between HER2/CEP17 ratio and nodal involvement was observed (p=0.02). Conclusion: Patients with HER2 equivocal status have no significantly higher risk of recurrence.

Background: Although tumor-infiltrating lymphocytes (TILs) have been associated with a favorable prognosis in triplenegative breast cancer (TNBC) patients, this marker is not currently considered robust enough for entering the clinical practice. In the present study, we assessed the clinical validity of the guidelines recently issued by the International TIL Working Group in a large retrospective series of well-annotated TNBC patients. Patients and methods: TILs were evaluated in all the full-face H & E sections from 897 consecutive TNBC (i.e. tumors with >1% of ER and PgR immunoreactivity and absence of HER2 overexpression or amplification) patients diagnosed and treated at the European Institute of Oncology between 1995 and 2010 (median follow-up 8.2 years, range 6 months to 18 years). All mononuclear cells were evaluated in the stromal area within the borders of the invasive tumor, reported as a percentage value and treated as a continuous variable in survival analysis. Results: The median percentage of TILs was 20%, and 21.9% of the cases had =50% (lymphocyte predominant breast cancer, LPBC) TILs. At univariable survival analysis, TILs were a significant predictor of better disease-free survival (DFS), distant disease-free survival (DDFS) and overall survival (OS) (P < 0.0001). Multivariable analysis confirmed that each 10% increase in TILs strongly predicted better survival, independent of patients' age, lymph node status, tumor size, histological grade, peritumoral vascular invasion and Ki-67 labeling index. Patients with LPBC had a 10-year survival rate of 71%, 84% and 96% for DFS, DDFS and OS, respectively. Stratified analysis revealed a positive correlation between TILs and OS across all the subgroups analyzed. Conclusion: Our data support the analytical validity of the recently issued TILs evaluation guidelines in the clinical practice.

Purpose Oncoplastic surgery is a well-established discipline that combines conserving treatment for breast cancer with immediate plastic reconstruction. Although widely practiced, the oncologic outcomes of this combined approach are reported only in small series. The aim of the present paper is to assess the safety of oncoplastic surgery for invasive primary breast cancer. Methods We compared 454 consecutive patients who underwent an oncoplastic approach between 2000 and 2008 for primary invasive breast tumors (study group) with twice the number of patients who received conservation alone in the same interval time (control group). Disease free survival and overall survival were estimated using the Kaplan-Meier method. The log-rank test was used to assess differences between groups. Results The median follow-up was 7.2 years. The overall survival is similar within the two groups, being 91.4% and 91.3% at 10-yr in the study group and in the control group respectively. The disease free survival is slightly lower in the oncoplastic group (69 vs.73.1% at 10-yr). The difference is not statistically significant. Discussion. We have compared a large series of primary breast cancer patients that have undergone oncoplastic surgery (454) with a control group (908) and they were followed for a prolonged period of time. It provides the best available evidence to suggest that oncoplastic surgery is a safe and reliable treatment option for the managing of invasive breast cancer.

Background: Characteristics such as gender and lifestyle are not taken in account in colorectal cancer screening and surveillance recommendations. Aims: To identify factors associated with advanced neoplasia at initial and surveillance colonoscopy. Methods: In this observational study, 750 individuals with positive faecal occult blood test, aged 50-74 years, underwent a first screening colonoscopy in 2007-2009. We collected anthropometric data as well as data on physical activity, smoking and drinking habits, fruit and vegetable consumption and low-dose aspirin use through a questionnaire. Results: At initial colonoscopy advanced neoplasia (n = 399, 53.2%) was positively associated with age, male gender, smoking and alcohol drinking, and inversely associated with physical activity, fruit and vegetables consumption and long-term use of aspirin. These 7 factors were used to calculate a risk score, ranging from 0 (no unfavourable characteristics) to 7 (all unfavourable characteristics present), which was significantly associated with advanced neoplasia (odds ratio 1.55 for one point increase, P < 0.01). Among the 372 adenoma patients who returned for follow-up surveillance colonoscopy, the score remained associated with advanced neoplasia (odds ratio 1.28 for one point increase, P = 0.01). Conclusion: Besides age and gender, modifiable factors such as lifestyle and aspirin use were associated with the risk of advanced neoplasia at initial and surveillance colonoscopy.
