Background: Prehabilitation is safe, feasible and may improve a range of outcomes in patients with oesophago-gastric cancer (OGC). Recent studies have suggested the potential of prehabilitation to improve body composition, sarcopenia and physical fitness, reduce surgical complications and improve quality of life. Despite this, prehabilitation services are not offered throughout all OGC centres in the UK.

Article Synopsis
  • This study investigates the impact of pathological lymph node (LN) regression after neoadjuvant chemotherapy on survival rates in patients with esophageal adenocarcinoma, addressing a gap in existing research and defining LN response classifications.
  • Conducted across five UK centers, the study analyzed 17,930 LNs from 763 patients, assigning scores based on the extent of residual tumor found in the nodes after treatment, with survival outcomes assessed using advanced statistical methods.
  • Results showed that patients with complete or partial LN response had significantly lower mortality rates compared to those with poor or no LN response, highlighting LN regression as a vital prognostic factor that should be considered alongside traditional staging methods.

Introduction: Better predictive markers are needed to deliver individualized care for patients with primary esophagogastric cancer. This exploratory study aimed to assess whether pre-treatment imaging parameters from dynamic contrast-enhanced MRI and F-fluorodeoxyglucose (F-FDG) PET/CT are associated with response to neoadjuvant therapy or outcome.

Materials And Methods: Following ethical approval and informed consent, prospective participants underwent dynamic contrast-enhanced MRI and F-FDG PET/CT prior to neoadjuvant chemotherapy/chemoradiotherapy ± surgery.

A tumour-positive proximal margin (PPM) after extended gastrectomy for oesophagogastric junction (OGJ) adenocarcinoma is observed in approximately 2-20% of patients. Although a PPM is an unfavourable prognostic factor, the clinical relevance remains unclear as it may reflect poor tumour biology. This narrative review analyses the most relevant literature on PPM after gastrectomy for OGJ cancers.

Purpose: Long-lasting symptoms and reductions in quality of life are common after oesophago-gastric surgery. Post-operative follow-up has traditionally focussed on tumour recurrence and survival, but there is a growing need to also identify and treat functional sequelae to improve patients' recovery.

Methods: An electronic survey was circulated via a British national charity for patients undergoing oesophago-gastric surgery and their families.

Background: Peri-operative chemotherapy improves survival in patients with locally advanced oesophago-gastric adenocarcinoma. Two regimens with proven survival benefits are epirubicin, cisplatin plus capecitabine or fluorouracil (Medical Research Council Adjuvant Gastric Infusional Chemotherapy, MAGIC) and fluorouracil plus leucovorin, oxaliplatin, and docetaxel (FLOT). This study aimed to compare the effect of these regimens on survival (primary aim) and pathological response, surgical complications, adverse events and chemotherapy completion rates.

Background: Neoadjuvant chemotherapy is often used prior to surgical resection for oesophageal adenocarcinoma but remains ineffective in a high proportion of patients. The histological Mandard tumour regression grade is used to determine chemoresponse but is not available at the time of treatment decision-making. The aim of this cohort study was to identify factors that predict chemotherapy response prior to surgery.

Background: Most patients presenting with oesophageal cancer do so with advanced disease not suitable for surgery. However, there are examples of encouraging survival following surgery in highly selected patients who respond well to chemotherapy.

Methods: This was a retrospective cohort study of patients who presented with advanced but nonvisceral metastatic oesophageal cancer.

Objectives: Metastatic involvement of nonregional supraclavicular or superior mediastinal lymph nodes in distal oesophageal cancer is rare but has important implications for prognosis and management. The management of nonregional lymph nodes which appear indeterminate on CT and FDG PET-CT (subcentimeter nodes or those with preserved normal morphology, but increased FDG avidity) can present a diagnostic dilemma. This study investigates the incidence, work-up and clinical significance of nonregional clinically indeterminate FDG avid lymph nodes.

Background & Aims: Prophylactic hypothermia, often used in critically ill patients with traumatic brain injury, reduces energy expenditure and may affect energy delivered by nutrition therapy. The primary objective of this study was to measure energy expenditure in hypothermic patients over the first 3 days after traumatic brain injury (TBI). Secondary objectives included comparison of measured energy expenditure and nutrition delivery to day 7.

The long-term effects of delivering approximately 100% of recommended calorie intake via the enteral route during critical illness compared with a lesser amount of calories are unknown. Our hypotheses were that achieving approximately 100% of recommended calorie intake during critical illness would increase quality-of-life scores, return to work, and key life activities and reduce death and disability 6 months later. We conducted a multicenter, blinded, parallel group, randomized clinical trial, with 3,957 mechanically ventilated critically ill adults allocated to energy-dense (1.
