Background To develop direct and indirect (response) mapping algorithms from the
European Organization for Research and Treatment of Cancer Quality of Life Questionnaire …

Purpose To determine the external validity of existing mapping algorithms for predicting EQ-
5D-3L utility values from EORTC QLQ-C30 responses and to establish their generalizability …

Abstract Background The European Organisation for Research and Treatment of Cancer
Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) is the instrument most frequently …

Objectives: The aim of this article is to map the European Organization for Research and
Treatment of Cancer (EORTC) QLQ C‐30 onto the EQ‐5D measure to enable the estimation …

Purpose To develop a mapping algorithm for a conversion of the EORTC QLQ-C30 and
EORTC QLQ BR-23 into the EQ-5D-derived utilities in metastatic breast cancer (MBC) …

Objective This study aimed to develop mapping algorithms from the European Organization
for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-BR53 …

Background. Clinical trials in cancer frequently include cancer-specific measures of health
but not preference-based measures such as the EQ-5D that are suitable for economic …

Background This study aimed to compare the measurement properties of the EQ-5D-3L (3L)
and EQ-5D-5L (5L) in cancer patients. Methods A consecutive sample of inpatients with …

Objectives. To assess the external validity of mapping algorithms for predicting EQ-5D-3L
utility values from EORTC QLQ-C30 responses not previously validated and to assess …

Abstract Background Although cancer-specific Health-related Quality-of-Life measures are
commonly included in randomized clinical trials or other prospective non-randomized …
