An exploration into the quality of life of women treated for cervical cancer

Background

Cervical cancer mainly occurs among women from the developing world, and women face unique challenges in terms of their disease and treatment. Most women present with advanced cervical cancer and receive the standard curative treatment with external beam radiotherapy and brachytherapy with or without chemotherapy.

Objectives

To describe the quality of life (QOL) of women treated for cervical cancer during treatment (M0), at 6 months after completing treatment (M6) and at 12 months after treatment (M12).

Methods

A cross-sectional design, calculated sample size (n = 153) and convenience sampling were used. Data were collected through structured interviews, and the EORTC QLQ-C30 and EORTC QLQ CX24 served as data collection instruments. Descriptive statistics were used to analyse the data, and the Kruskal–Wallis H test was used to compare the mean responses across the groups (p ≤ 0.05).

Results

The mean age of the respondents was 50.6 years (standard deviation [SD] 11.9). The global health status improved significantly in contrast with the functional scores. Financial difficulties were rampant, especially during the treatment phase. Insomnia and urinary frequency were the most cumbersome problems and remained so even after treatment.

Conclusions

Despite an improvement in the global health, cervical cancer and its treatment had a negative influence on the QOL in all domains of lives of these women. Assessing the QOL of patients during treatment and follow-up visits would allow nurses to develop interventions to address distressing problems timeously. In addition, Africa’s nurses should assess social functioning and develop programmes to prevent social dysfunction.

Reliability and validity of the Amharic version of European Organization for Research and Treatment of cervical Cancer module for the assessment of health related quality of life in women with cervical cancer in Addis Ababa, Ethiopia

Background

Cervical cancer is among the leading gynecological cancers affecting women worldwide. Maintenance and improvement of cervical cancer patients‘health related quality of life (HRQoL) is an important issue. The cervical cancer specific quality of life module of the European Organization for Research and Treatment of Cancer (EORTC QLQ-CX24) is the most commonly used tool, however, it is not validated in Ethiopia. Hence, the present study aimed to assess the psychometric properties of the tool among Ethiopian cervical cancer patients.

Methods

Hospital based cross-sectional study was done in Tikur Anbessa Specialized Hospital (TASH), Addis Ababa, Ethiopia from January to February, 2018. The module was translated through forward-backward translation approach and pilot tested according to the EORTC Guidelines. One hundered and seventy one patients with confirmed cervical cancer were enrolled for the study. Amharic versions of EORTC QLQ-C30 and EORTC QLQ-CX24 were used to collect data along with socio-demographic and clinical characteristics. Descriptive statistics were used to assess socio-demographic and clinical characteristics of patients. The Psychometric properties of the EORTC QLQ-CX24 were evaluated in terms of acceptability, internal consistency, construct, concurrent and known group validity using SPSS version 22.

Results

One hundred seventy one cervical cancer patients were enrolled in the study, with a mean age of 52.15 ± 10.4 years. The EORTC QLQ-CX24 was found to be acceptable with high compliance and low missing responses. The Cronbach’s alpha ranged from 0.70–0.84, indicating the reliability of the scales. Convergent and discriminant validity in multitrait scaling analysis was adequate. The EORTC QLQ-C30 subscales and EORTC QLQ-CX24 subscales had a weak to strong correlation, indicating concurrent validity. The scales and single-item measures were able to discriminate between subgroups of patients differing with regard to performance status, cancer stage and treatment status, indicating clinical validity.

Conclusion

Amharic version of the EORTC QLQ-CX24 questionnaire is a valid and reliable tool and could be used for clinical and epidemiological cancer researches to study the HRQoL of patients with cervical cancer in Ethiopia.

An analysis of the psychometric properties of the translated versions of the European Organisation for the Research and Treatment of Cancer QLQ CX24 questionnaire in the two South African indigenous languages of Xhosa and Afrikaans

This study evaluates the psychometric properties of the Xhosa and Afrikaans version, the European Organization for Research and Treatment of Cancer (EORTC) of the Quality of Life Questionnaire Cervical Cancer Module (QLQ-CX24). Translated Xhosa and Afrikaans versions, EORTC QLQ-CX24 and the core questionnaire (the EORTC QLQ-C30) were completed by 66 Xhosa and 142 Afrikaans speaking women newly diagnosed with cervical cancer. Construct reliability and validity of the EORTC QLQ-CX24 questionnaire were assessed via factor analysis, multi-trait scaling analyses and known group comparisons. The mean age was similar in the groups with a mean age of the Xhosa group (52 year) and Afrikaans group (49.2 year) (P = 0.25). The study groups had a high unemployment rate of, respectively, 52% (Xhosa) and 51% (Afrikaans) (P = 0.35). The Xhosa group had a statistically significant higher incidence of advanced stage (III and IV) disease (P = 0.006). Scale reliability was confirmed by Cronbach's α coefficients for internal consistency, which ranged from 0.73 to 0.81 (Xhosa) and 0.73 to 0.76 (Afrikaans). Clinical validity of both language versions was demonstrated by the ability to discriminate among different stages of cervical cancer. The translated Xhosa and Afrikaans versions of the EORTC QLQ-CX24 were found to be reliable and valid measure of quality of life of women with cervical cancer.
