Abstract Previous studies have shown an increased risk of colorectal cancer (CRC) among moderate to heavy alcohol consumers relative to non-drinkers; however, the relationship between alcohol and CRC survival remains unclear. Using data from the international Colon Cancer Family Registry (CCFR), we assessed the association between pre-diagnostic alcohol intake and survival outcomes after CRC diagnosis, overall and stratified by patient and tumor attributes. CRC cases were identified via population-based cancer registries at four CCFR study sites, with diagnoses of incident, invasive CRC from 1997 to 2006. Study participants completed a risk factor questionnaire at enrollment which included information on several pre-diagnostic behaviors, including consumption of wine, beer, and liquor. Prospective follow-up for survival outcomes was conducted for 4858 CRC cases with complete data on alcohol consumption. Using Cox proportional hazards regression models with delayed entry to account for the time between diagnosis and study enrollment, we compared non-drinkers (i.e., alcohol intake <1 drink per week) to individuals who consumed, on average, <1 serving of alcohol per day (but ≥1 per week), and those who consumed ≥1 serving per day in the years preceding CRC diagnosis. Separate analyses were carried out for overall and disease-specific survival. All models were adjusted for age at diagnosis, sex, study site, year of diagnosis, smoking history, CRC screening history, and body mass index. Over a mean follow-up of 7.5 years, 1872 (39%) study participants died, 1110 (59%) of whom died from CRC. Pre-diagnostic beer and liquor consumption were not associated with CRC survival; however, consumption of ≥1 serving of wine per day was modestly associated with more favorable overall [hazard ratio (HR) = 0.80, 95% confidence interval (CI): 0.63-1.00] and disease-specific survival (HR = 0.83, 95% CI: 0.62-1.12). In stratified analyses, having consumed ≥1 serving of wine per day was slightly, but not statistically significantly, more strongly associated with overall survival among men than among women (HR = 0.71 vs. 0.91, respectively, p-heterogeneity = 0.12) and among those aged ≤50 than those aged >50 years (HR = 0.66 vs. 0.84, p-heterogeneity = 0.35). Similar patterns were noted with respect to disease-specific survival. There were no differences in the relationships between wine consumption and survival outcomes stratified by tumor site, microsatellite instability, BRAF-mutation, or CpG island methylator phenotype status. These results suggest that wine consumption prior to CRC diagnosis is modestly associated with more favorable survival after CRC diagnosis. This modest inverse association does not appear to be limited to specific colorectal tumor subtypes and extends beyond overall survival to disease-specific outcomes. Citation Format: Amanda I.

Abstract Peripheral T-cell lymphomas (PTCLs) represent a heterogeneous group of T-cell malignancies that generally demonstrate aggressive clinical behavior, often are refractory to standard therapy, and remain significantly understudied. The most common World Health Organization subtype is PTCL, not otherwise specified (NOS), essentially a “wastebasket” category because of inadequate understanding to assign cases to a more specific diagnostic entity. Identification of novel fusion genes has contributed significantly to improving the classification, biologic understanding, and therapeutic targeting of PTCLs. Here, we integrated mate-pair DNA and RNA next-generation sequencing to identify chromosomal rearrangements encoding expressed fusion transcripts in PTCL, NOS. Two of 11 cases had novel fusions involving VAV1, encoding a truncated form of the VAV1 guanine nucleotide exchange factor important in T-cell receptor signaling. Fluorescence in situ hybridization studies identified VAV1 rearrangements in 10 of 148 PTCLs (7%). These were observed exclusively in PTCL, NOS (11%) and anaplastic large cell lymphoma (11%). In vitro, ectopic expression of a VAV1 fusion promoted cell growth and migration in a RAC1-dependent manner. This growth was inhibited by azathioprine, a clinically available RAC1 inhibitor. We also identified novel kinase gene fusions, ITK-FER and IKZF2-ERBB4, as candidate therapeutic targets that show similarities to known recurrent oncogenic ITK-SYK fusions and ERBB4 transcript variants in PTCLs, respectively. Additional novel and potentially clinically relevant fusions also were discovered. Together, these findings identify VAV1 fusions as recurrent and targetable events in PTCLs and highlight the potential for clinical sequencing to guide individualized therapy approaches for this group of aggressive malignancies.

Introduction Acute respiratory failure (ARF) often presents and progresses outside of the intensive care unit. However, recognition and treatment of acute critical illness is often delayed with inconsistent adherence to evidence-based care known to decrease the duration of mechanical ventilation (MV) and complications of critical illness. The goal of this trial is to determine whether the implementation of an electronic medical record-based early alert for progressive respiratory failure coupled with a checklist to promote early compliance to best practice in respiratory failure can improve the outcomes of patients at risk for prolonged respiratory failure and death. Methods and analysis A pragmatic stepped-wedged cluster clinical trial involving 6 hospitals is planned. The study will include adult hospitalised patients identified as high risk for MV >48 hours or death because they were mechanically ventilated outside of the operating room or they were identified as high risk for ARF on the Accurate Prediction of PROlonged VEntilation (APPROVE) score. Patients with advanced directives limiting intubation will be excluded. The intervention will consist of (1) automated identification and notification of clinician of high-risk patients by APPROVE or by invasive MV and (2) checklist of evidence-based practices in ARF (Prevention of Organ Failure Checklist—PROOFCheck). APPROVE and PROOFCheck will be developed in the pretrial period. Primary outcome is hospital mortality. Secondary outcomes include length of stay, ventilator and organ failure-free days and 6-month and 12-month mortality. Predefined subgroup analysis of patients with limitation of aggressive care after study entry is planned. Generalised estimating equations will be used to compare patients in the intervention phase with the control phase, adjusting for clustering within hospitals and time. Ethics and dissemination The study was approved by the institutional review boards. Results will be published in peer-reviewed journals and presented at international meetings. Trial registration number NCT02488174.

Aim The aim of this trial was to evaluate the efficacy and tolerability of ubrogepant (MK-1602), a calcitonin gene-related peptide receptor antagonist (CGRP-RA), for the acute treatment of migraine. Methods This double-blind, placebo-controlled study randomized 834 participants to treat one migraine attack with ubrogepant 1 mg, 10 mg, 25 mg, 50 mg, 100 mg, or placebo in a 1:1 ratio. The co-primary endpoints were pain freedom and headache response at two hours. The first primary hypothesis tested the dose-response trend for two-hour pain freedom using a logistic regression model. Subsequent hypotheses tested the effects of each dose on the co-primary endpoints, using a closed sequential testing procedure to control for multiplicity. Results A total of 527 participants received ubrogepant and 113 received placebo. A positive response trend in the proportion of participants achieving two-hour pain freedom was demonstrated ( p < 0.001). Ubrogepant 100 mg was significantly superior to placebo for two-hour pain freedom (25.5% vs 8.9%) but not for two-hour headache response. Per the prespecified multiplicity strategy, this nonsignificant result precluded further formal hypothesis testing, although the 50 mg and 25 mg doses demonstrated nominal significance over placebo for two-hour pain freedom (unadjusted p < 0.05). Overall, adverse events were similar between ubrogepant and placebo. Conclusion This trial supports ubrogepant’s efficacy and provides further evidence that CGRP-RAs are viable options for the acute treatment of migraine.

Abstract Background: The Trial Assigning Individualized Options for Treatment (TAILORx) is a prospective trial evaluating the role of endocrine therapy or chemoendocrine therapy in patients 18-75 years of age with estrogen receptor (ER)-positive, HER2-negative breast cancer, a primary tumor between 0.6-5.0 cm, and negative axillary nodes, a population for whom chemotherapy is typically recommended or least considered based on National Comprehensive Cancer Center Network (NCCN) guidelines. Methods: The trial was designed to demonstrate non-inferiority of endocrine therapy compared with chemoendocrine therapy in the randomized group with an Oncotype DX Recurrence Score (RS) of 11-25. Patients with a low RS &lt; 11 were assigned to endocrine therapy alone and with a high RS &gt; 25 assigned to chemoendocrine therapy, and both groups were followed in a prospective registry. The definition of an intermediate RS differed in this trial (RS 11-25) from the original reports (RS 18-30) in order to reduce the risk of chemotherapy undertreatment in patients with a mid-range or low RS (Sparano & Paik. J Clin Oncol 2008; 26:721-728). Results: The trial enrolled 10,273 patients between April 2006 and October 2010, of whom 6907 patients (67.2%) had a mid-range RS of 11-25, 1737 (16.9%) had a high RS &gt; 25, and 1639 (15.9%) had a low RS of &lt; 11. At the fourth planned interim analysis, the ECOG-ACRIN data monitoring committee recommended that the study continue as planned for the randomized group with a RS 11-25, and that the results be released to the investigators for the low risk group with a RS &lt;11. The characteristics of the low risk registry population are as follows: age 50 or less (27%), 51-60 (35%), &gt; 60 (39%); tumor size &lt; 1 cm (8%), 1-2 cm (61%), &gt; 2 cm (31%); histologic grade low (34%), intermediate (59%), high (7%); breast conservation (68%) or mastectomy (32%). Initial endocrine therapy included tamoxifen in 35%, aromatase inhibitors in 59%, ovarian function suppression in 3%, and unspecified therapy in 3%; 5 patients received adjuvant chemotherapy (1 of whom relapsed). Five-year rates (and 95% confidence intervals [CI]) for low RS group were 99.2% (98.5, 99.6%) for distant relapse free interval, 98.5% (97.7, 99.1%) for relapse-free interval, 93.7% (92.2, 94.9%) for invasive disease free survival, and 98.2% (97.3, 98.7%) for overall survival. Information regarding ER, PR, and HER2 RNA expression will be presented. Conclusions: Despite meeting guidelines for recommending or at least considering adjuvant chemotherapy based on classical clinicopathologic features, the risk of recurrence was very low at 5 years in patients with ER-positive, HER2-negative, axillary node-negative breast cancer and a low RS of &lt; 11 treated with endocrine therapy alone without chemotherapy.

Objective To assess the rates and predictors of traversing steps essential to good medical care for chronic migraine, including: (1) medical consultation, (2) accurate diagnosis, and (3) minimal pharmacologic treatment. Candidate predictors included socioeconomic, demographic, and headache‐specific variables. Background Previous research has established that barriers to effective management for episodic migraine include the absence of health insurance, lack of appropriate medical consultation, failure to receive an accurate diagnosis, and not being offered a regimen with acute and preventive treatments. Methods/Design The Chronic Migraine Epidemiology and Outcomes (CaMEO) Study, a longitudinal web‐based panel study of migraine, included a cross‐sectional module focused on patterns of and barriers to medical care. Participants eligible for this analysis met the study criteria for chronic migraine, had evidence of headache‐related disability, and provided data on health insurance status. The main outcomes in the current analysis included the proportion of respondents who sought consultation for headache with a designated healthcare professional, self‐reported receiving a diagnosis of chronic or transformed migraine, and received minimal pharmacologic treatment for headache with a focus on prescribed acute and preventive treatments. Results In the CaMEO Study, 80,783 respondents provided study data, 16,789 (20.8% of respondents) met criteria for migraine, and 1476 (8.8% of those with migraine) met chronic migraine criteria. In total, 1254 participants (85.0% of those with chronic migraine) met inclusion criteria for this analysis. Of those, 512 respondents (40.8%) reported currently consulting with a healthcare professional for headache. Odds of consulting increased with increasing age (OR 1.02; 95% CI 1.01–1.03), body mass index (BMI) (OR 1.01; 95% CI 1.00–1.03), migraine‐related disability (OR 1.02; 95% CI 1.00–1.04), and migraine severity (OR 1.16; 95% CI 1.11–1.22) and presence of health insurance (OR 4.61; 95% CI 3.05–6.96). Among those consulting a healthcare professional, 126 (24.6%) received an accurate diagnosis and 56 of those with a correct diagnosis (44.4%) received both acute and preventive pharmacologic treatments; odds of a CM diagnosis were higher for women (OR 1.93; 95% CI 1.03–3.61), those with greater migraine severity (OR 1.25; 95% CI 1.14–1.37), and those currently consulting a specialist (OR 2.38; 95% CI 1.54–3.69). No predictors of receiving appropriate treatment were identified among those currently consulting. Among our sample of people with chronic migraine, only 56 (4.5%) individuals successfully traversed the series of 3 barriers to successful chronic migraine care (ie, consulted a healthcare professional for migraine, received an accurate diagnosis, and were prescribed minimal acute and preventive pharmacologic treatments). Conclusion Our findings suggest that <5% of persons with chronic migraine traversed 3 barriers to receiving care for headache (consultation, diagnosis, and treatment), representing a large unmet need for improving care in this population. Predictors of consulting a healthcare professional included age, having health insurance, greater migraine‐related disability, and greater migraine symptom severity. Among those consulting, predictors of an appropriate diagnosis included consulting a specialist, female sex, and greater migraine severity. Public health efforts are needed to improve outcomes for patients with chronic migraine by a range of interventions and educational efforts aimed at improving consultation rates, diagnostic accuracy, and adherence to minimal pharmacologic treatment.
