The EORTC Quality of Life Questionnaire for patients with colorectal cancer: EORTC QLQ-CR29 Validation Study for Spanish patients

IntroductionThe EORTC Quality of Life (QL) Group has developed a questionnaire -the EORTC QLQ-CR29- for evaluating QL in colorectal cancer. The aim of this study is to assess the psychometric properties of the EORTC QLQ-CR29 when applied to a sample of Spanish patients.Materials and methodsEighty-four locally advanced rectal cancer patients in the treatment follow-up period after receiving surgery and neoadjuvant chemoradiotherapy were included in the study. Seventy subjects also had adjuvant chemotherapy. Patients completed both the EORTC QLQ-C30 and the QLQ-CR29 once. The psychometric evaluation of the questionnaire’s structure, reliability, and convergent, divergent and known-groups validity was performed.ResultsMultitrait scaling analysis showed that three of the multi-item scales met the standards of convergent and discriminant validity. These same scales reached the 0.7 Cronbach’s coefficient criterion or were close to it. In both analyses exceptions were observed in the blood and mucus in stool scale. Correlations between the scales of the QLQ-C30 and the module were low (r<0.02) in most cases. A few areas with more related content had higher correlations (r<0.05). Group comparison analyses showed differences in QL between groups of patients based on age, comorbidity, performance status, receipt of adjuvant chemotherapy and surgery modality.ConclusionsThe EORTC QLQ-CR29 is a reliable and valid instrument when applied to a sample of Spanish rectal cancer patients. These results are in line with those of the EORTC validation study.

The EORTC cancer outpatient satisfaction with care questionnaire in ambulatory radiotherapy: EORTC OUT-PATSAT35 RT. Validation study for Spanish patients

Objectives: The EORTC OUT‐PATSAT35 RT questionnaire evaluates the satisfaction with care (SC) expressed by cancer outpatients treated with radiotherapy. In this study we assess the psychometric properties of the OUT‐PATSAT35 RT when applied to a sample of Spanish patients.

Determinants of patient satisfaction with care in a Spanish oncology day hospital and its relationship with quality of life.

This study evaluates satisfaction with care (SC) in cancer patients treated at a Spanish day hospital to identify SC determinants and assess the relationship between SC and quality of life.

The cancer outpatient satisfaction with care questionnaire for chemotherapy, OUT-PATSAT35 CT: a validation study for Spanish patients

PurposeThe OUT-PATSAT35 CT questionnaire evaluates satisfaction with care expressed by cancer outpatients receiving chemotherapy. This study assesses the psychometric properties of the OUT-PATSAT35 CT when applied to a sample of Spanish patients.MethodsOne hundred seventy-six patients with different tumour sites and disease stages completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (QLQ)-C30, the OUT-PATSAT35 CT, the Oberst patients’ perception of care quality and satisfaction scales (OS) and the item on intention to recommend the hospital (IR). Psychometric evaluation of the structure, reliability and validity of the questionnaire was conducted.ResultsMultitrait scaling analysis showed that 32 of 34 item-scale correlation coefficients met the standards for convergent validity and that many of them met the standards for discriminant validity. Cronbach’s coefficients were good (0.78–0.97) for all scales except doctor availability and environment. Correlations between the QLQ-C30 and the OUT-PATSAT35 CT were low (≤0.40). Correlations between IR and the OUT-PATSAT35 CT were moderate, and correlations between this questionnaire and the OS were fairly low. Areas whose contents were more related had higher correlation coefficients (>0.50) and vice versa (<0.1). Male patients, elderly patients, those with higher education levels, those with higher scores in four OS and patients who had not received surgery showed higher satisfaction with care in several OUT-PATSAT35 CT areas.ConclusionsThe OUT-PATSAT35 CT is a reliable and valid instrument when applied to a sample of Spanish cancer patients. These results are in line with those of the validation study conducted by the authors of the questionnaire and with the validation study for Spain of the OUT-PATSAT35 RT.

The EORTC information questionnaire, EORTC QLQ-INFO25. Validation study for Spanish patients.

IntroductionThe EORTC QLQ-INFO25 evaluates the information received by cancer patients. This study assesses the psychometric properties of the QLQ-INFO25 when applied to a sample of Spanish patients.Materials and methodsA total of 169 patients with different cancers and stages of disease completed the EORTC QLQINFO25, the EORTC QLQ-C30 and the information scales of the inpatient satisfaction module EORTC IN-PATSAT32 on two occasions during the patients’ treatment and follow-up period. Psychometric evaluation of the structure, reliability, validity and responsiveness to changes was conducted. Patient acceptability was assessed with a debriefing questionnaire.ResultsMulti-trait scaling confirmed the 4 multi-item scales (information about disease, medical tests, treatment and other services) and eight single items. All items met the standards for convergent validity and all except one met the standards of item discriminant validity. Internal consistency for all scales (α>0.70) and the whole questionnaire (α>0.90) was adequate in the three measurements, except information about the disease (0.67) and other services (0.68) in the first measurement, as was test-retest reliability (intraclass correlations >0.70). Correlations with related areas of IN-PATSAT32 (r>0.40) supported convergent validity. Divergent validity was confirmed through low correlations with EORTC QLQ-C30 scales (r<0.30). The EORTC QLQ-INFO-25 discriminated among groups based on gender, age, education, levels of anxiety and depression, treatment line, wish for information and satisfaction. One scale and an item showed changes over time.ConclusionsThe EORTC QLQ-INFO 25 is a reliable and valid instrument when applied to a sample of Spanish cancer patients. These results are in line with those of the EORTC validation study.

Feasibility, tolerability, and efficacy of the concurrent addition of erlotinib to thoracic radiotherapy in locally advanced unresectable non-small-cell lung cancer: a Phase II trial

Purpose Although many studies have confirmed the synergic effects of combining chemotherapy (CT) and radiotherapy (RT), clinical data evaluating safety and efficacy of erlotinib in combination with RT in locally advanced non-small-cell lung cancer (NSCLC) are limited. The aim of this study was to determine the feasibility, tolerability, and efficacy of the concurrent addition of erlotinib to the standard three-dimensional conformal thoracic RT in patients with unresectable or locally advanced NSCLC who are not candidates for receiving standard CT. Patients and methods Feasibility and tolerability, assessed by evaluating adverse events (AEs), and effectiveness, by calculating progression-free survival (PFS), overall survival (OS), cancer-specific survival (CSS), and objective response rate (ORR), were analyzed in 30 patients receiving RT alone and 60 receiving RT and erlotinib. Results Erlotinib with RT showed an extended CSS and a higher rate of complete responses compared with RT alone. No differences between groups were found regarding OS, PFS, and ORR. AEs were significantly higher in the combined treatment, which mainly included cutaneous toxicity, dyspnea, fatigue, hyporexia, diarrhea, and infection. Erlotinib did not increase the toxicity produced by RT. Conclusion The combination of erlotinib with RT produced, in our study, a scarce clinical benefit in the treatment of unresectable or locally advanced NSCLC, limited to complete responses and longer CSS rate compared with RT alone. Increased toxicity events were associated with combined therapy, which mainly included cutaneous toxicity. In our opinion, further studies in molecularly unselected lung cancer patients treated with EGFR TKIs and RT are not indicated. The use of biomarkers for the identification of patients that are most likely to benefit from this treatment is an essential next step in the research of this condition.

Incidence, predictors and prognostic significance of thromboembolic disease in patients with advanced ALK-rearranged non-small cell lung cancer

Thromboembolic disease is fairly common in patients with lung cancer [1–3]. This incidence seems to be higher in patients with lung adenocarcinomas [4], with approximately 15% of those with advanced stage disease developing venous thromboembolisms (VTE) during the whole course of their disease [5–7]. Pulmonary adenocarcinomas are a heterogeneous group of diseases that can be stratified according to the presence of major oncogenic driver alterations. Anaplastic lymphoma kinase (ALK) rearrangements are detected in approximately 4% of these cases [8]. Isolated reports have suggested that patients bearing ALK-rearranged tumours might have a higher than expected incidence of thromboembolisms [9, 10]. In the present study, we have analysed the incidence, predictors and prognostic significance of thromboembolic events in a large, multi-institutional and homogeneous cohort of advanced stage patients with ALK-rearranged lung cancers from Spain and Portugal. Our primary objective was to estimate the incidence of thromboembolic events and their association with overall survival in these patients.
