Objective: To discern recurrence risk stratification and investigate its influence on postoperative surveillance in patients with esophageal adenocarcinoma (EAC) after neoadjuvant chemoradiotherapy (CRT). Background: Reports documenting recurrence risk stratification in EAC after neoadjuvant CRT are scarce. Methods: Between 1998 and 2014, 601 patients with EAC who underwent neoadjuvant CRT followed by esophagectomy were included for analysis. The pattern, site, timing, and frequency of the first recurrence and potential prognostic factors for developing recurrences were analyzed. This cohort was used as the training set to propose a recurrence risk stratification system, and the stratification was further validated in another cohort of 172 patients. Results: A total of 150 patients (25.0%) achieved pathologic complete response (pCR) after neoadjuvant CRT and the rest were defined as the non-pCR group (n = 451) in the training cohort. After a median follow-up of 63.6 months, the pCR group demonstrated a significantly lower locoregional (4.7% vs 19.1%) and distant recurrence rate (22.0% vs.44.6%) than the non-pCR group (P < 0.001). Based on independent prognostic factors, patients were stratified into 4 recurrence risk categories: pCR with clinical stage I/II, pCR with clinical stage III, non-pCR with pN0, and non-pCR with pN+, with corresponding 5-year recurrence-free survival rates of 88.7%, 65.8%, 55.3%, and 33.0%, respectively (P < 0.001). The risk stratification was reproducible in the validation cohort. Conclusions: We proposed a recurrence risk stratification system for EAC patients based on pathologic response and pretreatment clinical stage. Risk-based postoperative surveillance strategies could be developed for different risk categories.

Hemophagocytic lymphohistiocytosis (HLH) is a syndrome of severe immune activation and dysregulation resulting in extreme and often life‐threatening inflammation. HLH has been well recognized in pediatric populations, and most current diagnostic and therapeutic guidelines are based on pediatric HLH. Recently there has been recognition of HLH in adults, especially secondary to immune deregulation by an underlying rheumatologic, infectious, or malignant condition. This review is focused on malignancy‐associated HLH (M‐HLH), in which possible mechanisms of pathogenesis include severe inflammation, persistent antigen stimulation by the tumor cells, and loss of immune homeostasis because of chemotherapy, hematopoietic stem cell transplantation, or infection. Previously considered rare, M‐HLH may occur in up to 1% of patients with hematologic malignancies. M‐HLH is often missed or diagnosed late in most published studies, and it has been associated with a poor median survival of less than 2 months. Identification of the clinical and laboratory features specific to M‐HLH in adults may allow early detection, consultation with HLH experts, and intervention. Improved management of adult M‐HLH with optimal combinations of T‐lympholytic and immunosuppressive agents and the incorporation of novel agents based on the pediatric experience hopefully will improve outcomes in adults with M‐HLH.

ABSTRACTBioinformatics tools are imperative for the in depth analysis of heterogeneous high‐throughput data. Most of the software tools are developed by specific laboratories or groups or companies wherein they are designed to perform the required analysis for the group. However, such software tools may fail to capture “what the community needs in a tool”. Here, we describe a novel community‐driven approach to build a comprehensive functional enrichment analysis tool. Using the existing FunRich tool as a template, we invited researchers to request additional features and/or changes. Remarkably, with the enthusiastic participation of the community, we were able to implement 90% of the requested features. FunRich enables plugin for extracellular vesicles wherein users can download and analyse data from Vesiclepedia database. By involving researchers early through community needs software development, we believe that comprehensive analysis tools can be developed in various scientific disciplines.

BackgroundOral anticoagulation (OAC) therapy is associated with increased periprocedural risks after cardiac implantable electronic device (CIED) implantation. Patterns of anticoagulation management involving non–vitamin K antagonist oral anticoagulants (NOACs) have not been characterized.HypothesisAnticoagulation strategies and outcomes differ by anticoagulant type in patients undergoing CIED implantation.MethodsUsing the nationwide Outcomes Registry for Better Informed Treatment of Atrial Fibrillation, we assessed how atrial fibrillation (AF) patients undergoing CIED implantation were cared for and their subsequent outcomes. Outcomes were compared by oral anticoagulant therapy (none, warfarin, or NOAC) as well as by anticoagulation interruption status.ResultsAmong 9129 AF patients, 416 (5%) underwent CIED implantation during a median follow‐up of 30 months (interquartile range, 24–36). Of these, 60 (14%) had implantation on a NOAC. Relative to warfarin therapy, those on a NOAC were younger (70.5 years [range, 65–77.5 years] vs 77 years [range, 70–82 years]), had less valvular heart disease (15.0% vs 31.3%), higher creatinine clearance (67.3 [range, 59.7–99.0] vs 65.8 [range, 50.0–91.6]), were more likely to have persistent AF (26.7% vs 22.9%), and use concomitant aspirin (51.7% vs 35.2%). OAC therapy was commonly interrupted for CIED in 64% (n = 183 of 284) of warfarin patients and 65% (n = 39 of 60) of NOAC patients. Many interrupted patients received intravenous bridging anticoagulation: 33/183 (18%) interrupted warfarin and 4/39 (10%) interrupted NOAC patients. Thirty‐day periprocedure bleeding and stroke adverse events were infrequent.ConclusionsManagement of anticoagulation among AF patients undergoing CIED implantation is highly variable, with OAC being interrupted in more than half of both warfarin‐ and NOAC‐treated patients. Bleeding and stroke events were infrequent in both warfarin and NOAC‐treated patients.

SummaryThe oral proteasome inhibitor ixazomib is approved in the United States, European Union and other countries, in combination with oral lenalidomide and dexamethasone (Rd), for the treatment of patients with multiple myeloma who have received at least one prior therapy. Approval was based on the global, randomised, double‐blind, placebo‐controlled Phase III TOURMALINE‐MM1 study of ixazomib‐Rd (IRd) versus placebo‐Rd in patients with relapsed/refractory multiple myeloma. IRd resulted in a significant improvement in progression‐free survival versus placebo‐Rd (median: 20·6 vs. 14·7 months; hazard ratio 0·74). Common toxicities observed more commonly with IRd versus placebo‐Rd were thrombocytopenia, nausea, vomiting, diarrhoea, constipation, rash, peripheral neuropathy, peripheral oedema and back pain; these were generally grade 1/2 in severity except for thrombocytopenia (19% vs. 9% grade 3/4), which appeared manageable and reversible, with no differences between arms in significant bleeding or dose discontinuations. No cumulative toxicities were observed, indicating the potential feasibility of long‐term IRd treatment. Safety data from TOURMALINE‐MM1 are reviewed and guidance for managing clinically relevant adverse events associated with IRd is provided. Most toxicities were manageable with supportive care and dose delays or reductions as needed. Clinicians should be aware of and understand these potential side effects to optimise and prolong patient benefit.

AbstractBackgroundUnilateral radiotherapy (RT) of oropharyngeal carcinomas is accepted for patients with lateralized primary and low‐volume nodal disease. Utilizing prospectively defined criteria of laterality and staging positron emission tomography (PET)/CT, we studied outcomes in patients with advanced‐stage oropharyngeal cancer undergoing unilateral RT.MethodsThirty‐seven patients with oropharyngeal tumors >1 cm from midline regardless of node status underwent unilateral RT and were followed prospectively. Patient characteristics: T1 = 11; T2 = 22; T3 = 4; N0 = 3; N1 = 9; N2a = 3; N2b = 21; and Nx = 1. Dosimetry were determined and weekly National Comprehensive Cancer Network (NCCN) distress thermometer data were collected.ResultsAt median follow‐up of 32 months, 3‐year locoregional control, contralateral regional failure, distant metastasis‐free survival, and disease‐free survival were 96%, 0%, 7%, and 93%, respectively.ConclusionLow rates of contralateral neck failure are demonstrated utilizing prospectively defined criteria for unilateral RT. The tolerances of contralateral organs are respected and patients report low to moderate levels of distress throughout treatment.
