BACKGROUND: Metastasis is the main cause of cancer patient deaths and remains a poorly characterized process. It is still unclear when in tumor progression the ability to metastasize arises and whether this ability is inherent to the primary tumor or is acquired well after primary tumor formation. Next-generation sequencing and analytical methods to define clonal heterogeneity provide a means for identifying genetic events and the temporal relationships between these events in the primary and metastatic tumors within an individual...

BACKGROUND: Inflammatory breast cancer (IBC) is a rare, aggressive form of breast cancer associated with HER2 amplification, with high risk of metastasis and an estimated median survival of 2.9 y. We performed an open-label, single-arm phase II clinical trial (ClinicalTrials.gov NCT01325428) to investigate the efficacy and safety of afatinib, an irreversible ErbB family inhibitor, alone and in combination with vinorelbine in patients with HER2-positive IBC. This trial included prospectively planned exome analysis before and after afatinib monotherapy...

Extracorporeal Membrane Oxygenation (ECMO) is widely used in Acute Respiratory Distress Syndrome (ARDS) and myocarditis. Severe vector-mediated diseases may be complicated by ARDS or myocarditis, which are both associated with a high mortality rate. We present six cases of severe dengue, malaria, and acute Chagas disease that were treated with ECMO from September 2007 to September 2015. Patients included two pediatric and four adults (ages 12 to 48). Survival to decannulation was 83% and to discharge was 66%...

There is little published data on the safety and effectiveness of mobile (inter-hospital) extra-corporeal membrane oxygenation (ECMO) in adults, particularly focusing on the cannulation strategy. We sought to study the outcomes of patients cannulated with a bicaval dual lumen catheter needing mobile compared to conventional ECMO. Specifically, we evaluated the safety of using this cannulation strategy during initiation, in transport and overall performance. Multivariate adjustment was performed to report on adjusted 6-month survival as well as complications and performance from cannulation and the ECMO run...

This was a retrospective study to investigate the predictive and prognostic ability of quantitative computed tomography phenotypic features in patients with non-small cell lung cancer (NSCLC). 661 patients with pathological confirmed as NSCLC were enrolled between 2007 and 2014. 592 phenotypic descriptors was automatically extracted on the pre-therapy CT images. Firstly, support vector machine (SVM) was used to evaluate the predictive value of each feature for pathology and TNM clinical stage. Secondly, Cox proportional hazards model was used to evaluate the prognostic value of these imaging signatures selected by SVM which subjected to a primary cohort of 138 patients, and an external independent validation of 61 patients...

The >90% rates of overall survival for children with Wilms tumour are remarkable and have been achieved at the same time as reducing treatment for most patients. However, beneath this headline figure, 20% of patients still relapse after first-line therapy and up to 25% of survivors report severe late effects. The aim of the SIOP-RTSG is to improve outcomes and to reduce acute and late treatment toxic effects in all children.

A meta-analysis was performed to examine the efficiency and safety of trastuzumab in patients with advanced gastric and gastroesophageal cancer (AGC). By searching multiple databases from 1990 to March 2016, all randomized controlled trials (RCTs) which compared the effect of trastuzumab-combined chemotherapy (TC) versus chemotherapy alone (CT) in gastric cancer would be included. Five RCTs with a total of 875 patients were included. Trastuzumab can improve the overall survival (OS) rate, progression-free survival (PFS), one-year survival rate, two-year survival rate and overall response rate (ORR) of patients with AGC...

We investigated the prognostic role of regulatory T cells (Tregs) in patients with hepatocellular carcinoma (HCC). Relevant evidence regarding prognostic significance of Tregs was systematically searched in MEDLINE and Embase databases. A meta-analysis was performed to compare survival in patients with high or low Tregs level (either in peripheral blood or tumor). Eighteen studies were identified that fulfilled for the eligibility criteria and were included for data synthesis. Our pooled hazard ratios (HRs) demonstrated that increased Tregs intratumoral accumulation was significantly associated with worse overall survival (HR=2...

Patients who mildly progressed after first-line chemotherapy were administered arsenic trioxide (ATO) 5-10 mg intravenously daily. Thirty-nine patients were finally enrolled in the study, of whom 19 patients received first-line chemotherapy with ATO infusion while 20 patients did not. Progression-free survival at 4 months was 89.2 and 62.7% (p = 0.043) for the ATO group and the control group, respectively, while the 2-year overall survival was 61 and 16.4% (p = 0.032).
