Preoperative exercise to improve fitness in patients undergoing complex surgery for cancer of the lung or oesophagus (PRE-HIIT): protocol for a randomized controlled trial.

Background: Patients with cancer of the lung or oesophagus, undergoing curative treatment, usually require a thoracotomy and a complex oncological resection. These surgeries carry a risk of major morbidity and mortality, and risk assessment, preoperative optimisation, and enhanced recovery after surgery (ERAS) pathways are modern approaches to optimise outcomes. Pre-operative fitness is an established predictor of postoperative outcome, accordingly, targeting pre-operative fitness through exercise prehabilitation has logical appeal.

The Radiation-Induced Bystander Effect (RIBE) and its Connections with the Hallmarks of Cancer.

Radiation therapy is one of the pillars of cancer treatment, with approximately one half of all cancer patients receiving it as part of their standard of care. Emerging evidence indicates that the biological effects of radiation are not limited to targeted cells. The radiation-induced bystander effect (RIBE) refers to the plethora of biological phenomena occurring in nonirradiated cells as a result of signal transmission from an irradiated cell.

Physical recovery in the first six months following oesophago-gastric cancer surgery. Identifying rehabilitative needs: a qualitative interview study.

Purpose: To investigate patients' perspectives of their physical recovery in the first six months post oesophago-gastric cancer surgery.

Materials And Methods: Semi-structured interviews were held at St James's Hospital, Dublin, with participants who were 4 weeks to 6 months post-oesophagectomy/gastrectomy. Interviews were an average of 14 min and included questions pertaining to physical recovery post-oesophagectomy/gastrectomy.

Effect of neoadjuvant chemoradiation on preoperative pulmonary physiology, postoperative respiratory complications and quality of life in patients with oesophageal cancer.

Background: It remains controversial whether neoadjuvant chemoradiation (nCRT) for oesophageal cancer influences operative morbidity, in particular pulmonary, and quality of life. This study combined clinical outcome data with systematic evaluation of pulmonary physiology to determine the impact of nCRT on pulmonary physiology and clinical outcomes in locally advanced oesophageal cancer.

Methods: Consecutive patients treated between 2010 and 2016 were included.

Changes in gut hormones, glycaemic response and symptoms after oesophagectomy.

Background: Oesophagectomy is associated with reduced appetite, weight loss and postprandial hypoglycaemia, the pathophysiological basis of which remains largely unexplored. This study aimed to investigate changes in enteroendocrine function after oesophagectomy.

Methods: In this prospective study, 12 consecutive patients undergoing oesophagectomy were studied before and 10 days, 6, 12 and 52 weeks after surgery.

Postoperative critical care and high-acuity care provision in the United Kingdom, Australia, and New Zealand.

Background: Decisions to admit high-risk postoperative patients to critical care may be affected by resource availability. We aimed to quantify adult ICU/high-dependency unit (ICU/HDU) capacity in hospitals from the UK, Australia, and New Zealand (NZ), and to identify and describe additional 'high-acuity' beds capable of managing high-risk patients outside the ICU/HDU environment.

Methods: We used a modified Delphi consensus method to design a survey that was disseminated via investigator networks in the UK, Australia, and NZ.

Attenuation of satiety gut hormones increases appetitive behavior after curative esophagectomy for esophageal cancer.

Background: Reduced appetite and weight loss are common after esophagectomy (ES), and this cohort demonstrates an exaggerated postprandial satiety gut hormone response. Satiety gut hormones modulate food reward, resulting in reduced energy intake.

Objectives: This study aimed to determine the effect of satiety gut hormone modulation by measuring the effect of the somatostatin analog octreotide on appetitive behavior among patients after ES.

Risk factors for loss of bone mineral density after curative esophagectomy.

Unlabelled: Micronutrient and fat malabsorption and altered enteroendocrine signaling occur after esophagectomy for cancer; however, the impact of malnutrition on bone health in this cohort has not been previously investigated. In this study, the prevalence of osteoporosis increased after curative surgery, associated with disease-specific, treatment-related, and population risk factors.

Purpose: Improved oncologic outcomes in esophageal cancer (EC) have resulted in increased survivorship and a focus on long-term quality of life.

The Mitochondrial Genes , and are Linked with Alterations in Mitochondrial Membrane Potential in Barrett's Esophagus.

Barrett's esophagus and esophageal cancer lack prognostic markers that allow the tailoring of personalized medicine and biomarkers with potential to provide insight into treatment response. This study aims to characterize mitochondrial function across the metaplasia-dysplasia-adenocarcinoma disease sequence in Barrett's esophagus and examines the functional effect of manipulating mitochondrial genes. Mitochondrial genes of interest were validated in in vitro cell lines across the metaplasia (QH), dysplasia (GO) and adenocarcinoma (OE33) sequence and in in vivo patient tissue samples.

Quantifying postoperative mobilisation following oesophagectomy.

Objective: Early mobilisation is in integral component of postoperative recovery following complex surgical procedures such as oesophageal cancer resections, however evidence to guide early mobilisation protocols in critical care settings is limited. Furthermore, little is known about actual mobilisation levels postoperatively. This study quantified postoperative mobilisation post- oesophagectomy and investigated barriers to mobility.

Obesity and gastrointestinal cancer: the interrelationship of adipose and tumour microenvironments.

Increasing recognition of an association between obesity and many cancer types exists, but how the myriad of local and systemic effects of obesity affect key cellular and non-cellular processes within the tumour microenvironment (TME) relevant to carcinogenesis, tumour progression and response to therapies remains poorly understood. The TME is a complex cellular environment in which the tumour exists along with blood vessels, immune cells, fibroblasts, bone marrow-derived inflammatory cells, signalling molecules and the extracellular matrix. Obesity, in particular visceral obesity, might fuel the dysregulation of key pathways relevant to both the adipose microenvironment and the TME, which interact to promote carcinogenesis in at-risk epithelium.

High-grade chondrosarcoma of the larynx: a case report and literature review.

A 64-year-old male presented with a 2-month history of sudden onset dysphonia. Endoscopic evaluation of the larynx revealed a complete right vocal cord palsy. Computed tomography of the neck revealed a mass medial to the right thyroid associated with the cricoid cartilage.

The RESTORE Randomized Controlled Trial: Impact of a Multidisciplinary Rehabilitative Program on Cardiorespiratory Fitness in Esophagogastric cancer Survivorship.

Objective: The Rehabilitation Strategies in Esophagogastric cancer (RESTORE) randomized controlled trial evaluated the efficacy of a 12-week multidisciplinary program to increase the cardiorespiratory fitness and health-related quality of life (HRQOL) of esophagogastric cancer survivors.

Background: Patients following treatment for esophagogastric cancer are at risk of physical deconditioning, nutritional compromise, and sarcopenia. Accordingly, compelling rationale exists to target these impairments in recovery.

Physical decline and its implications in the management of oesophageal and gastric cancer: a systematic review.

Purpose: The management of oesophageal and gastric cancer can cause significant physical decline, impacting on completion rates and outcomes. This systematic review aimed to (i) determine the impact of chemotherapy, chemoradiotherapy and surgery on physical function; (ii) identify associations between physical function and post-operative outcomes; and (iii) examine the effects of rehabilitation on physical function.

Methods: We included randomised controlled trials (RCT), non-RCTs of interventions and cohort studies that measured physical function by objective means in patients with oesophageal or gastric cancer.

Risks of breast or ovarian cancer in BRCA1 or BRCA2 predictive test negatives: findings from the EMBRACE study.

Purpose: BRCA1/BRCA2 predictive test negatives are proven noncarriers of a BRCA1/BRCA2 mutation that is carried by their relatives. The risk of developing breast cancer (BC) or epithelial ovarian cancer (EOC) in these women is uncertain. The study aimed to estimate risks of invasive BC and EOC in a large cohort of BRCA1/BRCA2 predictive test negatives.

Prevalence and clinical association of MET gene overexpression and amplification in patients with NSCLC: Results from the European Thoracic Oncology Platform (ETOP) Lungscape project.

Introduction: In a well-defined NSCLC cohort of the ETOP Lungscape program, we explored the epidemiology of IHC MET overexpression and amplification, their inter-correlation, and their association to outcome.

Methods: Resected NSCLC were assessed for MET gene copy number (GCN) and expression using silver in-situ hybridization (SISH) and immunohistochemistry (IHC) on TMAs in a multicenter setting. MET amplification was defined as MET/centromere ratio≥2 (with average MET GCN≥4), high MET GCN as CGN≥5 and MET IHC+ as ≥2+ intensity in ≥50% of tumor cells.

Sarcopenia: Prevalence, and Impact on Operative and Oncologic Outcomes in the Multimodal Management of Locally Advanced Esophageal Cancer.

Objective: The aim of this article was to study the prevalence and significance of sarcopenia in the multimodal management of locally advanced esophageal cancer (LAEC), and to assess its independent impact on operative and oncologic outcomes.

Summary Of Background Data: Sarcopenia in cancer may confer negative outcomes, but its prevalence and impact on modern multimodal regimens for LAEC have not been systematically studied.

Methods: Two hundred fifty-two consecutive patients were studied.

Erlotinib and bevacizumab in patients with advanced non-small-cell lung cancer and activating EGFR mutations (BELIEF): an international, multicentre, single-arm, phase 2 trial.

Background: The tyrosine kinase inhibitor erlotinib improves the outcomes of patients with advanced non-small-cell lung carcinoma (NSCLC) harbouring epidermal growth factor receptor (EGFR) mutations. The coexistence of the T790M resistance mutation with another EGFR mutation in treatment-naive patients has been associated with a shorter progression-free survival to EGFR inhibition than in the absence of the T790M mutation. To test this hypothesis clinically, we developed a proof-of-concept study, in which patients with EGFR-mutant NSCLC were treated with the combination of erlotinib and bevacizumab, stratified by the presence of the pretreatment T790M mutation.

Multimodality treatment for esophageal adenocarcinoma: multi-center propensity-score matched study.

Background: The primary aim of this study was to compare survival from neoadjuvant chemoradiotherapy plus surgery (NCRS) versus neoadjuvant chemotherapy plus surgery (NCS) for the treatment of esophageal or junctional adenocarcinoma. The secondary aims were to compare pathological effects, short-term mortality and morbidity, and to evaluate the effect of lymph node harvest upon survival in both treatment groups.

Methods: Data were collected from 10 European centers from 2001 to 2012.

Randomized Phase III Trial of Erlotinib versus Docetaxel in Patients with Advanced Squamous Cell Non-Small Cell Lung Cancer Failing First-Line Platinum-Based Doublet Chemotherapy Stratified by VeriStrat Good versus VeriStrat Poor. The European Thoracic Oncology Platform (ETOP) EMPHASIS-lung Trial.

Introduction: Docetaxel and erlotinib are registered second-line treatments for wild-type EGFR NSCLC. Previous studies suggested a predictive value of the VeriStrat test in second-line therapy of NSCLC, classifying patients as either VeriStrat good or VeriStrat poor. EMPHASIS-lung aimed at exploring this predictive effect in patients with squamous cell NSCLC.

Physiology, pathophysiology and therapeutic implications of enteroendocrine control of food intake.

With the increasing prevalence of obesity and its associated comorbidities, strides to improve treatment strategies have enhanced our understanding of the function of the gut in the regulation of food intake. The most successful intervention for obesity to date, bariatric surgery effectively manipulates enteroendocrine physiology to enhance satiety and reduce hunger. Areas covered: In the present article, we provide a detailed overview of the physiology of enteroendocrine control of food intake, and discuss its pathophysiologic correlates and therapeutic implications in both obesity and gastrointestinal disease.

Risk Factors for Anastomotic Stricture Post-esophagectomy with a Standardized Sutured Anastomosis.

Background: Benign anastomotic strictures occur frequently after esophagectomy, and impact on postoperative recovery, nutritional status, and quality of life. This large cohort study explored the incidence of stricture after transthoracic (2- and 3-stage) and transhiatal resections with uniform single-layer sutured anastomotic technique, and aimed to identify independent risk factors.

Methods: Patients undergoing esophagectomy with gastric conduit reconstruction between February 2001 and October 2014 were studied prospectively.
