BACKGROUNDThe authors report on the development and validation of a cervical cancer module for the European Organization for Research and Treatment of Cancer (EORTC) Quality‐of‐Life (QoL) questionnaire (QLQ), which was designed to assess disease‐specific and treatment‐specific aspects of QoL in patients with cervical cancer.METHODSThe cervical cancer module (EORTC QLQ‐CX24) was developed in a multicultural, multidisciplinary setting to supplement the EORTC QLQ‐C30 core questionnaire. The QLQ‐C30 and the cervical cancer module were administered to 346 patients with cervical cancer who underwent radical hysterectomy and received radiotherapy and chemotherapy. Psychometric analyses were performed by using data from 2 independent samples.RESULTSThe QLQ‐CX24 consists of 3 multiitem scales and 5 single‐item scales. Multitrait scaling analyses revealed high internal consistencies for the subscales with Cronbach α coefficients ranging from .72 to .87 (Symptom Experience, .72; Body Image, .86; Sexual/Vaginal Functioning, .87). Convergent and discriminant validity were fulfilled with scaling errors below 3%. The QLQ‐CX24 was capable of discriminating between clinical subgroups. All items exhibited good compliance with <3% missing values. Most patients completed the EORTC QLQ‐C30 and the QLQ‐CX24 in <15 minutes (86%), and many did not require any assistance to complete the questionnaires (65%).CONCLUSIONSThe current psychometric analyses supported the content and construct validity and the reliability of the EORTC QLQ‐CX24 module. This newly developed module is a useful instrument for assessing the QoL of patients who are treated for cervical cancer both in clinical trials and in clinical practice.

Cervical cancer survivors treated with adjuvant radiotherapy are more likely at risk for impaired QoL. Survivors treated with surgery or adjuvant chemotherapy return to a similar level of QoL as women without a history of cancer. Although the sexual activity rate is lower in irradiated patients their sexual pleasure is similar to patients after surgery and chemotherapy.

Background:Little is known about whether changes in health-related quality of life (HRQoL) scores from baseline during treatment also predict survival, which we aim to investigate in this study.Methods:We analysed data from 391 advanced non-small-cell lung cancer (NSCLC) patients enrolled in the EORTC 08975 study, which compared palliative chemotherapy regimens. HRQoL was assessed at baseline and after each chemotherapy cycle using the EORTC QLQ-C30 and QLQ-LC13. The prognostic significance of HRQoL scores at baseline and their changes over time was assessed with Cox regression, after adjusting for clinical and socio-demographic variables.Results:After controlling for covariates, every 10-point increase in baseline pain and dysphagia was associated with 11% and 12% increased risk of death with hazard ratios (HRs) of 1.11 and 1.12, respectively. Every 10-point improvement of physical function at baseline (HR=0.93) was associated with 7% lower risk of death. Every 10-point increase in pain (HR=1.08) was associated with 8% increased risk of death at cycle 1. Every 10-point increase in social function (HR=0.91) at cycle 2 was associated with 9% lower risk of death.Conclusions:Our findings suggest that changes in HRQoL scores from baseline during treatment, as measured on subscales of the EORTC QLQ-C30 and QLQ-LC13, are significant prognostic factors for survival.
