Translation and cultural adaptation of EORTC QLQ-LC 29 into Nepalese language for lung cancer patients in Nepal

Abstract

Background: The quality of life (QoL) of patients with lung cancer (LC) may be affected by disease-related limitations such as patients' functioning, the severity of symptoms, financial problems resulting along with the side effects of the treatment. The objective of this study was to translate LC-specific QoL questionnaire EORTC QLQ-LC29 into Nepalese language for Nepalese LC patients. Methods: In the process of translation, the European Organization for Research and Treatment of Cancer (EORTC) translations guidelines were followed. The translated questionnaire was pilot-tested in a sample of 15 patients with LC. Descriptive statistics were calculated with SPSS version 21.0. Results: All steps of the EORTC translation guideline were followed successfully. Fifteen lung cancer patients were included in the pilot study. Sixty percent were male and the mean age was 49.87 (range 21-76 years). For all items not related to thoracic surgery, patients used the entire range of the response options from 1 to 4 and no missing responses were observed. The highest mean (indicating a high symptom burden) was observed for the item number. 35 (shortness of breath; Mean = 3.33, SD = 1.11) and the lowest mean for an item number. 45 (dizzy; Mean = 1.73, SD = 0.96). Conclusion: The Nepalese version of EORTC QLQ-LC29 is a result of a successfully conducted rigorous translation procedure, and is highly comprehensible as well as acceptable to Nepalese LC patients. Thus, the Nepalese version of EORTC QLQ-LC29 is ready to be used in international clinical studies as well as in Nepalese clinical practice.

Translation and Adaptation of The EORTC QLQ-LC 29 for Use in Chinese Patients with Lung Cancer

“…During our pilot testing, eight items (27.6%) received comments from patients. The percentagewas relatively high compared with that in the pilot testing studies of the EORTC QLQ-LC29 in other languages [16][17]. This may be due to cultural differences.…”

“…As in similar projects [16][17], we adhered strictly to the EORTC translation guidelines and all the steps were audited by the EORTC Translation Unit. During the translation process, we met some di culties and gained some experience.…”

“…The results of the pilot testing of the simpli ed Chinese version of the EORTC QLQ-LC29 indicated that the symptom burden was low in Chinese patients with lung cancer [17]. A possible reason for this nding is that most of the enrolled patients had either just started lung cancer treatment or had completed it a long time ago.…”
