RESUMO

Cancer-related cachexia (CRC) is a common phenomenon in cervical cancer (CC), severely affecting clinical response, drug toxicity and survival. The patients' point of view should be evaluated to quantify the impact of CRC, and adequate instruments to do so are required. Thus, the study aimed to validate the Mexican-Spanish version of the QLQ-CAX24 instrument in women with CC. A cohort of women with CC answered the EORTC QLQ-C30 and QLQ-CAX24 instruments. The psychometric and clinimetric properties of the instruments were assessed. Two hundred and forty-four women were included; the mean age was 50 years (IQR: 41-60) and 188 (77%) were first diagnosed in locally advanced stages. The QLQ-CAX24 internal consistency test demonstrated adequate convergent (Spearman correlation coefficient 0.08-0.709) and divergent validity (Spearman correlation coefficient 0.006-0.471). Cronbach's alpha coefficients of the three multi-item scales were >0.5 (minimum 0.539, maximum 0.84). Patients with decreased handgrip strength, low fat-free mass, or high C-reactive protein levels had worse QLQ-CAX24 scale scores. Cachexia was diagnosed with the SCRINIO, Fearon and Evans criteria, and 31.5, 32.4 and 38.5% of women had cachexia, respectively. Patients with cachexia had the worst scores in terms of quality of life. The test re-test analysis did not show differences between visits in patients without malnutrition. The Mexican-Spanish version of the QLQ-CAX24 instrument is reliable and valid. Low handgrip strength, low fat-free mass and high C-reactive protein levels were associated with poor scale scores.
