This study defines the psychometric properties of the European Organisation for Research and Treatment of Cancer (EORTC) quality of life (QOL) questionnaire designed to measure the QOL of patients with ovarian cancer. The ovarian cancer module (EORTC QLQ-OV28) was developed to supplement the EORTC QLQ-C30. The core questionnaire and the QLQ-OV28 were prospectively administered to 368 ovarian ca...

Background The purpose of this study was to investigate quality of life (QOL) in patients receiving palliative radiotherapy (RT) for advanced lung cancer/lung metastases using the EORTC QLQ-LC13 and the EORTC QLQ-C15-PAL questionnaires. Methods Patients who received palliative RT for lung metastases or advanced lung cancer between November 2007 and October 2010 completed the EORTC QLQ-LC13 an...

BACKGROUND The European Organisation for Research and Treatment of Cancer (EORTC) quality of life colorectal questionnaire module (QLQ-CR38) was developed in 1999, and an update, the QLQ CR29 was published recently. To date the Danish version of the questionnaire has not been validated. The aim of this study was to examine the psychometric properties of the Danish version of EORTC QLQ-CR38. M...

OBJECTIVE To further evaluate the higher order measurement structure of the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 30 (QLQ-C30), with the aim of generating a summary score. STUDY DESIGN AND SETTING Using pretreatment QLQ-C30 data (N = 3,282), we conducted confirmatory factor analyses to test seven previously evaluated higher order...

BACKGROUND The aim of this study was to translate the EORTC quality of life questionnaire for brain cancer, the QLQ-BN20, into Persian, and to evaluate its psychometric properties when used among brain cancer patients in Iran. METHODS A standard backward and forward translation procedure was used to generate the Persian language version of the QLQ-BN20. The QLQ-BN20 was administered together ...

AIM OF THE STUDY To assess influencing factors and main health-related quality of life (HRQoL) issues in patients with cancers of the oesophago-gastric region using the European Organization for Research and Treatment of Cancer (EORTC) quality of life questionnaire Core 30 (QLQ-C30) and its oesophago-gastric module (QLQ-OG25). MATERIAL AND METHODS Patients were qualified for this study based ...

BACKGROUND A phase III trial demonstrated that cetuximab is the first agent in 30 years to improve survival when added to platinum-based chemotherapy (platinum-fluorouracil) first line for recurrent and/or metastatic squamous cell carcinoma of the head and neck (SCCHN). This analysis of the trial assessed the impact of treatment on quality of life (QoL). PATIENTS AND METHODS The European Orga...

BACKGROUND This Study Examined The Measurement Properties Of The Japanese Version Of The European Organisation for Research and Treatment of Cancer (EORTC) Hepatocellular Carcinoma-Specific Quality of Life Questionnaire (QLQ-HCC18). METHODS EORTC quality of life (QOL) translation guidelines were followed to create a Japanese version of the EORTC QLQ-HCC18. This was then administered to 192 pa...

Methods Systematic literature searches (MEDLINE, Embase, PsycINFO and CINAHL) identified articles reporting HRQL data after curative treatments for oesophageal cancer from validated patient-completed questionnaires. The most frequently used instruments were examined (EORTC QLQ-C30, QLQ-OES24, QLQ-OES18, SF-36 & FACT-E). Outcome reporting bias was explored by examining which of the instrument’s ...

BACKGROUND An important challenge of the longitudinal analysis of health-related quality of life (HRQOL) is the potential occurrence of a Response Shift (RS) effect. While the impact of RS effect on the longitudinal analysis of HRQOL has already been studied, few studies have been conducted on its impact on the determination of the Minimal Important Difference (MID). This study aims to investig...
