Quality of life (QOL) assessment requires clinically relevant questionnaires that yield accurate data. This study defined measurement properties and the clinical validity of the European Organisation for Research and Treatment of Cancer (EORTC) questionnaire module to assess QOL in oesophageal cancer. The oesophageal module the QLQ-OES24 and core(More)
Quality of life (QL) is an important outcome in clinical trials in oncology. There is currently no valid international QL measure for gastric cancer. This paper describes the development of a QL module for gastric cancer to supplement the European Organization for Research and Treatment of Cancer (EORTC) Quality of life (QLQ-C30) questionnaire. Phases I to(More)
INTRODUCTION Perioperative complications influence long- and short-term outcomes after esophagectomy. The absence of a standardized system for defining and recording complications and quality measures after esophageal resection has meant that there is wide variation in evaluating their impact on these outcomes. METHODS The Esophageal Complications(More)
BACKGROUND Little is known regarding the long-term, health-related quality of life (HRQL) of survivors of esophagectomy for cancer. METHODS Consecutive patients completed the validated European Organization for Research and Treatment of Cancer general quality-of life-questionnaire (QLQ-C30) and the esophageal-specific module (QLQ-OES18) before surgery and(More)
BACKGROUND Quality of life (QL) measurement provides detailed information about outcome from the patient's perspective. This study assessed the impact on short and long term QL of esophagectomy and palliative treatment in patients with esophageal carcinoma. METHODS Consecutive patients undergoing potentially curative esophagectomy or purely palliative(More)
Barrett's esophagus is an increasingly common disease that is strongly associated with reflux of stomach acid and usually a hiatus hernia, and it strongly predisposes to esophageal adenocarcinoma (EAC), a tumor with a very poor prognosis. We report the first genome-wide association study on Barrett's esophagus, comprising 1,852 UK cases and 5,172 UK(More)
Quality of life (QOL) assessments in patients with oesophageal cancer should provide clinically meaningful data that can assist management decision making. This study describes the development of a specific module for oesophageal cancer to use with the European Organisation into Research and Treatment of Cancer (EORTC) QOL questionnaire, the EORTC QLQ-C30.(More)
BACKGROUND & AIMS The incidence of esophageal and junctional adenocarcinoma has increased 6-fold in the past 30 years and 5-year survival remains approximately 20%. Current staging is limited in its ability to predict survival which has ramifications for treatment choices. The aim of this study was to generate and validate a molecular prognostic signature(More)
BACKGROUND Quality of life (QL) data are useful to evaluate the effectiveness of treatment. Accumulating evidence suggests that QL data may predict survival. AIMS In this study we investigated if baseline QL scores and changes in QL scores before and after intervention are prognostic for patients with oesophageal cancer. PATIENTS Between 1993 and 1995,(More)
BACKGROUND Combination chemoradiotherapy with or without surgery are internationally applied alternative strategies for potential cure of oesophageal cancer. This study compared health-related quality of life (HRQL) between patients selected for chemoradiation and those who had combination treatment including oesophagectomy. METHODS Patients with stage II(More)
