A Phase II Trial of Stereotactic Body Radiation Therapy and Androgen Deprivation for Oligometastases in Prostate Cancer (SBRT-SG 05).

PURPOSE: SBRT-Spanish Group-05 (ClinicalTrials.gov.Identifier: NCT02192788) is a collaborative (SBRT-SG, Grupo de Investigación Clínica en Oncología Radioterápica, and Sociedad Española de Oncología Radioterápica) prospective multicenter phase II trial testing stereotactic body radiation therapy (SBRT) and androgen deprivation therapy (ADT) in patients with oligorecurrent prostate cancer. METHODS AND MATERIALS: Two cohorts of patients with prostate cancer in an oligorecurrent stage (hormone-sensitive in the principal cohort and castration-resistant in the exploratory cohort) were assigned to receive ADT and SBRT for at least 24 months from the time of the enrollment. Concomitant treatment with chemotherapy, abiraterone, or enzalutamide was not allowed. Oncologic outcomes were assessed in both cohorts. Toxicity was prospectively analyzed. RESULTS: From 2014 to 2019, 81 patients with a total of 126 lesions from 14 centers met the inclusion criteria, 14 of whom were castration-resistant. With a median follow-up of 40 months (12-58 months), 3-year local recurrence-free survival was 92.5% (95% CI, 79.9%-96.3%) and 85.7% (95% CI, 48.2%-95.6%) in the principal and exploratory cohorts, respectively. In the principal cohort, biochemical relapse-free survival and metastasis progression-free survival at 1, 2, and 3 years were 91% (95% CI, 81%-95.8%), 73.7% (95% CI, 61.1%-82.8%), 50.6% (95% CI, 36.2%-63.3%), and 92% (95% CI, 83%-97%), 81% (95% CI, 70%-89%), and 67% (95% CI, 53%-77%), respectively. In the exploratory cohort, metastasis progression-free survival at 1, 2, and 3 years was 64% (95% CI, 34%-83%), 43% (95% CI, 18%-66%), and 26% (95% CI, 7%-51%), respectively. None of the patients developed grade III or higher toxicity or symptoms related to local progression, and only 2 (2.4%) patients developed grade II toxicity. CONCLUSIONS: The combination of SBRT and ADT is safe and shows favorable clinical outcomes in patients with hormone-sensitive and castration-resistant prostate cancer. Validation studies are needed in patients with castration-resistant prostate cancer.

General Spanish population normative data analysis for the EORTC QLQ-C30 by sex, age, and health condition.

PURPOSE: General population normative data for the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire facilitates interpretation of data assessed from cancer patients. This study aims to present normative data of the general Spanish population. METHODS/PATIENTS: Data were obtained from a prior larger study collecting EORTC QLQ-C30 norm data across 15 countries. Data were stratified by sex and age groups (18-39, 40-49, 50-59, 60-69 and > 70 years). Sex and age distribution were weighted according to population distribution statistics. Sex- and age-specific normative values were analysed separately, as were participants with versus those without health conditions. Multiple linear regression was used to estimate the association of each of the EORTC QLQ-C30 scales with the determinants age, sex, sex-by-age interaction term, and health condition. RESULTS: In total, 1,165 Spanish individuals participated in the study. Differences were found by sex and age. The largest sex-related differences were seen in fatigue, emotional functioning, and global QOL (Quality of Life), favouring men. The largest age differences were seen in emotional functioning, insomnia, and pain, with middle-aged groups having the worst scores. Those > 60 years old scored better than those < 60 years old on all scales except for physical functioning. Participants with no health conditions scored better in all QLQ-C30 domains. CONCLUSIONS: The present study highlights differences in HRQOL between specific sex/age strata and especially between people with and without a health condition in the general Spanish population. These factors must be considered when comparing general population HRQOL data with that of cancer patients.

Hypofractionation and Stereotactic Body Radiation Therapy in Inoperable Locally Advanced Non-small Cell Lung Cancer.

BACKGROUND AND AIM: Radiotherapy (RT) plays a key role in the control of locally advanced non-small cell lung cancer (LA-NSCLC). Throughout the years, different doses and fractionations of RT have been used in an attempt to optimize the results. Recently, special interest has been given to hypofractionation (hypoRT) and stereotactic body radiation therapy (SBRT). HypoRT is a relatively widespread treatment, although the accompanying level of evidence is limited. For its part, SBRT has been used specially to overdose specific areas of the disease as a boost after radiochemotherapy. In both cases, the study of how to integrate these RT tools with chemotherapy and immunotherapy is fundamental. In addition, the 2020 COVID-19 pandemic situation has sparked increased interest in hypofractionated treatments. In this review, we analyze the role of SBRT and hypoRT in the management of LA-NSCLC in accordance with current scientific evidence. RELEVANCE FOR PATIENTS: The objective of this article is to introduce professionals to the role that hypoRT and SBRT can play in the treatment of LA-NSCLC to offer the best treatment to their patients.

GOECP/SEOR radiotherapy guidelines for thymic epithelial tumours.

Thymic epithelial tumours (TET) are rare, heterogeneous neoplasms that range from resectable indolent tumours to aggressive thymic carcinomas with a strong tendency to metastasize. The pathological diagnosis is complex, in part due to the existence of several different classification systems. The evidence base for the management of TETs is scant and mainly based on non-randomised studies and retrospective series. Consequently, the clinical management of TETs tends to be highly heterogenous, which makes it difficult to improve the evidence level. The role of technological advances in the field of radiotherapy and new systemic therapies in the treatment of TETs has received little attention to date. In the present clinical guidelines, developed by the GOECP/SEOR, we review recent developments in the diagnosis and classification of TETs. We also present a consensus-based therapeutic strategy for each disease stage that takes into consideration the best available evidence. These guidelines focus primarily on the role of radiotherapy, including recent advances, in the management of TETs. The main aim of this document is to promote the standardisation of clinical practice and lay the foundations for future studies to clarify the main unresolved questions related to the optimal management of TET.

Identification of a Dexamethasone Mediated Radioprotection Mechanism Reveals New Therapeutic Vulnerabilities in Glioblastoma.

(1) Background: Despite the indisputable effectiveness of dexamethasone (DEXA) to reduce inflammation in glioblastoma (GBM) patients, its influence on tumour progression and radiotherapy response remains controversial. (2) Methods: We analysed patient data and used expression and cell biological analyses to assess effects of DEXA on GBM cells. We tested the efficacy of tyrosine kinase inhibitors in vitro and in vivo. (3) Results: We confirm in our patient cohort that administration of DEXA correlates with worse overall survival and shorter time to relapse. In GBM cells and glioma stem-like cells (GSCs) DEXA down-regulates genes controlling G2/M and mitotic-spindle checkpoints, and it enables cells to override the spindle assembly checkpoint (SAC). Concurrently, DEXA up-regulates Platelet Derived Growth Factor Receptor (PDGFR) signalling, which stimulates expression of anti-apoptotic regulators BCL2L1 and MCL1, required for survival during extended mitosis. Importantly, the protective potential of DEXA is dependent on intact tyrosine kinase signalling and ponatinib, sunitinib and dasatinib, all effectively overcome the radio-protective and pro-proliferative activity of DEXA. Moreover, we discovered that DEXA-induced signalling creates a therapeutic vulnerability for sunitinib in GSCs and GBM cells in vitro and in vivo. (4) Conclusions: Our results reveal a novel DEXA-induced mechanism in GBM cells and provide a rationale for revisiting the use of tyrosine kinase inhibitors for the treatment of GBM.

How to integrate stereotactic body radiation therapy and hypofractionation in the management of stage III lung cancer in the age of immunotherapy / Cómo integrar la radioterapia estereotáxica fraccionada y el hipofraccionamiento en el manejo del cáncer de pulmón localmente avanzado en la era de la inmunoterapia

The constant advances in the field of lung cancer immunotherapy have recently reached the treatment of locally advanced disease with the approval of durvalumab after concurrent chemoradiation. However, radiation therapy continues to be key for controlling the disease at this stage. Over the years, different strategies have been employed to try to optimize outcomes using radiotherapy, with cardiac and pulmonary toxicity as the main limitation on its success. The interest in the use of hypofractionation and stereotactic body radiation therapy for stage III non-small cell lung cancer has increased as knowledge regarding these kinds of treatments has been enhanced. Hypofractionation is a relatively frequent treatment, although the level of evidence that supports it is limited. For its part, stereotactic body radiation therapy has been particularly studied as a boost after chemoradiation, with encouraging results. In both cases, study of how to integrate these tools with chemotherapy and particularly with immunotherapy is essential, as they may have an immunomodulatory role

Real-world evidence of the effectiveness of ombitasvir-paritaprevir/r ± dasabuvir ± ribavirin in patients monoinfected with chronic hepatitis C or coinfected with human immunodeficiency virus-1 in Spain.

AIM: We describe the effectiveness and safety of the interferon-free regimen ombitasvir/paritaprevir/ritonavir plus dasabuvir with or without ribavirin (OBV/PTV/r ± DSV ± RBV) in a nationwide representative sample of the hepatitis C virus (HCV) monoinfected and human immunodeficiency virus-1/hepatitis C virus (HIV/HCV) coinfected population in Spain. MATERIAL AND METHODS: Data were collected from patients infected with HCV genotypes 1 or 4, with or without HIV-1 coinfection, treated with OBV/PTV/r ± DSV ± RBV at 61 Spanish sites within the initial implementation year of the first government-driven "National HCV plan." Effectiveness was assessed by sustained virologic response at post-treatment week 12 (SVR12) and compared between monoinfected and coinfected patients using a non-inferiority margin of 5% and a 90% confidence interval (CI). Sociodemographic and clinical characteristics or patients and adverse events (AEs) were also recorded. RESULTS: Overall, 2,408 patients were included in the intention-to-treat analysis: 386 (16%) were patients with HIV/HCV. Patient selection reflected the real distribution of patients treated in each participating region in Spain. From the total population, 96.6% (95% CI, 95.8-97.3%) achieved SVR12. Noninferiority of SVR12 in coinfected patients was met, with a difference between monoinfected and coinfected patients of -2.2% (90% CI, -4.5% - 0.2%). Only genotype 4 was associated with non-response to OBV/PTV/r ± DSV ± RBV treatment (p<0.001) in the multivariate analysis. Overall, 286 patients (11.9%) presented AEs potentially related to OBV/PTV/r ± DSV, whereas 347 (29.0%) presented AEs potentially related to ribavirin and 61 (5.1%) interrupted ribavirin. CONCLUSIONS: Our results confirm that OBV/PTV/r ± DSV ± RBV is effective and generally well tolerated in a representative sample of the HCV monoinfected and HCV/HIV coinfected population in Spain within the experience of a national strategic plan to tackle HCV.

Effect of mono/dual antiretroviral therapy on suppression of HCV and HIV during treatment of HCV infection in HIV/HCV-coinfected patients / Efecto de la terapia antirretroviral mono/dual sobre la supresión de VHC y VIH durante el tratamiento de la infección por VHC en pacientes co-infectados de VIH/VHC

OBJECTIVE: Data of hepatitis C treatment with direct-acting antivirals (DAAs) in HIV infected patients are limited to a few number of antiretroviral therapies (ART). The aim of this study was to assess the effectiveness and safety of non-conventional ART as monotherapy or dual therapy (MDT) when combined with DAA. METHODS: Retrospective review of HIV/HCV-coinfected patients treated with DAAs during one year in 3 centers. Sustained virologic response 12 weeks after therapy (SVR) and maintenance of HIV viral suppression were compared between patients receiving triple ART (TT) or MDT. RESULTS: Overall 485 patients were included (359 receiving TT and 126 MDT). HCV SVR was 93.4% (95%CI, 90.8% to 95.3%) in the intention-to-treat analysis without differences between groups: 92.8% on TT vs 95.2% on MDT (p = 0.3). HCV virological failure was associated with lower CD4 + cell count at baseline (for every 100-cell/μl increment: OR, 0.8; 95%CI, 0.7-0.9; p = 0.01) and with liver stiffness (for every 10-unit increment: OR, 1.5; 95%CI 1.2-1.8; p < 0.01). HIV-RNA during HCV treatment or 12 weeks after was detectable in 23 patients on TT (6.6%) and 9 (7.2%) patients on MDT (p = 0.8). The median (IQR) change in CD4 + cell count was not significantly different between the groups: 15 (-55 to 115) in TT vs -12 (-68 to 133) cells/μl in MDT (p = 0.8). CONCLUSION: DAAs obtain high rates of SVR among HIV/HCV-coinfected patients independently of whether TT or non-conventional ART is used. Suppression of HIV was maintained in both groups

OBJETIVO: Los datos sobre el tratamiento de la hepatitis C con antivirales de acción directa (AAD) en los pacientes infectados por VIH se limitan a un escaso número de terapias antirretrovirales (TARV). El objetivo de este estudio fue valorar la efectividad y seguridad de las TARV no convencionales, como monoterapia y terapia dual (MDT), al combinarse con AAD. MÉTODOS: Revisión retrospectiva de pacientes co-infectados por VIH/VHC, tratados con AAD durante un año en 3 centros. Se comparó la respuesta virológica sostenida (RVS) a las 12 semanas de la terapia, y el mantenimiento de la supresión viral del VIH, entre los pacientes que recibieron triple TARV o MDT. RESULTADOS: Se incluyó a un total de 485 pacientes (359 que recibieron triple TARV y 126 que recibieron MDT). La RVS de VHC fue del 93,4% (IC 95%: 90,8-95,3%) en el análisis por intención de tratar, sin diferencias entre grupos: 92,8% en el grupo triple TARV vs. 95,2% en el grupo MDT (p = 0,3). El fracaso virológico de VHC se asoció a un menor recuento basal de células CD4+ (para cada incremento de 100células/μl: OR: 0,8; IC 95%: 0,7-0,9; p = 0,01) y a la rigidez hepática (para cada incremento de 10 unidades: OR: 1,5; IC 95%: 1,2-1,8; p < 0,01). El ARN-VIH durante el tratamiento de VHC, o transcurridas 12 semanas, fue detectable en 23 pacientes en el grupo triple TARV (6,6%) y 9 (7,2%) pacientes en el grupo MDT (p = 0,8). El cambio medio (RIC) en el recuento de células CD4 + no fue significativamente diferente entre ambos grupos: 15 (de -55-115) en el grupo triple TARV vs. -12 (de -68-133) células/μl en el grupo MDT (p = 0,8). CONCLUSIÓN: Los AAD obtienen tasas altas de RVS entre los pacientes co-infectados de VIH/VHC, independientemente de si se utiliza triple TARV o TARV no convencional. La supresión de VIH se mantuvo en ambos grupos

Treatment Design and Rationale for a Randomized Trial of Prophylactic Cranial Irradiation With or Without Hippocampal Avoidance for SCLC: PREMER Trial on Behalf of the Oncologic Group for the Study of Lung Cancer/Spanish Radiation Oncology Group-Radiation Oncology Clinical Research Group.

BACKGROUND: Prophylactic cranial irradiation (PCI) is part of the usual treatment in most patients with small-cell lung cancer (SCLC) and response after treatment of the primary tumor. Clinical evidence suggests that radiation dose received by the hippocampus during whole brain radiotherapy might play a role in radiation-induced neurocognitive decline. PATIENTS AND METHODS: This study is a multicenter phase III trial (NCT02397733) randomizing SCLC patients after informed consent, to receive standard PCI treatment or PCI with hippocampus avoidance (PCI-HA) by using intensity modulated radiation therapy or volumetric modulated arc therapy. The primary objective is assessment of hippocampus-dependent memory functioning and safety after PCI with or without hippocampus sparing by the Free and Cued Selective Reminding Test. Secondary objectives are assessment of other neurotoxicity/quality of life, radiological brain abnormalities on magnetic resonance images, and evaluation of the incidence and location of brain metastases after PCI-HA compared with standard PCI. The originally planned sample size (n = 150) has been calculated to detect a 50% difference in the 3-month delayed recall score between the 2 treatment arms, with a statistical power of 80% (ß = 20%) and a significance level of 5% (α = 5%), with a maximum loss to follow-up of 10%. CONCLUSION: This study is an important step in introducing a new therapeutic approach to patients with SCLC candidates for PCI.

Quality of Life in Spanish advanced non-small-cell lung cancer patients: determinants of global QL and survival analyses.

PURPOSE: This paper studies the Quality of Life (QL) of Spanish advanced non-small-cell lung cancer (NSCLC) patients receiving platinum-doublet chemotherapy, compares our results with those from studies from other cultural areas, and identifies factors associated with global QL and survival prognostic variables. METHODS: EORTC QLQ-C30 and QLQ-LC13 questionnaires were completed three times by 39 patients along treatment and follow-up. Univariate and multivariate logistic regression analyses were performed to study global QL determinants (≤50 points considered low global-QL score). Analyses of prognostic variables for death were performed (Cox proportional hazards models). RESULTS: QL mean scores in the whole sample were moderately high, with limitations (>30) in physical, role, social functioning, emotional areas, fatigue, pain, neuropathy and global QL. Differences with studies from other cultural areas were mainly found in the lower score for dyspnoea (≥15 points). There were no significant differences in QL scores between the first and second assessments. In six areas, the third assessment was lower than the first and second: fatigue, hair loss (>20 points); physical, social functioning, neuropathy (10-20 points); emotional functioning (5-10 points). The best model to explain the chances of low QL includes, as explanatory variables, high emotional functioning as protective factor and fatigue as risk factor (R(2) = 0.70). Eight QL areas (four pain-related) and performance status showed a statistically significant association with survival. CONCLUSION: Patients adapted well to their disease and treatments. Platinum-doublet can be administered in advanced NSCLC patients. Our QL data are in line with those from other cultural areas.

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.

The EORTC QLQ-C15-PAL questionnaire: validation study for Spanish bone metastases patients.

PURPOSE: Quality of life (QL) is a key outcome for advanced disease cancer patients. The European Organization for Research and Treatment of Cancer (EORTC) has developed the QLQ-C15-PAL questionnaire, a short version of the QLQ-C30 for palliative care. The aim of the present study is to validate the QLQ-C15-PAL for use with Spanish patients with bone metastasis. METHODS: For this study, we used a consecutive sample of stage IV cancer patients with bone metastases who started radiotherapy with palliative intention. Two assessments were proposed for each patient: one on the first day of treatment and one a month after the end of the radiotherapy sessions. Psychometric evaluation of the structure, reliability, and validity was undertaken. RESULTS: One hundred and sixteen patients completed the first questionnaire and seventy five completed the second. Multitrait scaling analysis showed that all items met the standards for convergent validity, and all except the fatigue scale met the standards for divergent validity. Cronbach's coefficient met the 0.7 alpha criterion on all scales except pain (second assessment). Most QLQ-C15-PAL areas had low-to-moderate correlations with the other areas. Significant differences appeared in the comparisons between groups with regard to: patients who died before the second assessment (six areas); patients receiving chemotherapy before starting radiotherapy in the two assessments (three and four areas, respectively); the performance status in the two assessments (nine and eight areas); and the number of RT sessions received (four). Quality of life was better in the second assessment in nine areas. CONCLUSION: The QLQ-C15-PAL is a reliable and valid instrument when applied to a sample of Spanish patients. These results are in line with those of other validation studies.

Quality of life assessment by applying EORTC questionnaires to rectal cancer patients after surgery and neoadjuvant and adjuvant treatment.

BACKGROUND: Quality of Life (QoL) is a key element in rectal cancer (RC) patients. AIMS: this study assesses QoL in a sample of RC patients in their treatment follow-up period, and compares surgery modalities. PATIENTS AND METHODS: eighty four locally advanced RC patients who had received surgery and neoadjuvant chemoradiotherapy were included in the study. Of these, 70 had adjuvant chemotherapy. All patients completed the EORTC QLQ-C30 and the QLQ-CR29 once at least one year after completion of their treatment. Low anterior resection (LAR) patients also completed a Functional Evaluation questionnaire. RESULTS: QoL scores in the EORTC questionnaires for the sample as a whole were high in most dimensions, in line with the general population´s QoL values, although moderate limitations (> 30 points)were observed in urinary frequency, flatulence, impotence and sexual function. The scores for the Functional Evaluation were adequate (mean combined bowel function score of 18.2). LAR patients had a higher stool frequency than those with abdominoperineal resection (APR; p < 0.001). No differences in body image were found amongst LAR and APR patients. LAR patients with a lower anastomosis had higher faecal incontinence (p = 0.02), whereas those with a reservoir had better emotional functioning (p = 0.04) and higher faecal incontinence (p = 0.03). CONCLUSIONS: QoL scores and functional evaluation indicated patients had adapted to their disease and treatment. The few differences in QoL found between surgery modalities are in line with other recent studies and in contrast with earlier ones that suggested a lower QoL in APR patients.

The EORTC Quality of Life questionnaire for patients with colorectal cancer: EORTC QLQ-CR29 validation study for Spanish patients.

INTRODUCTION: The 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 QLQCR29 when applied to a sample of Spanish patients. MATERIALS AND METHODS: Eighty-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 QLQC30 and the QLQ-CR29 once. The psychometric evaluation of the questionnaire's structure, reliability, and convergent, divergent and known-groups validity was performed. RESULTS: Multitrait 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 QLQC30 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. CONCLUSIONS: The 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. METHODS: A total of 100 patients with different tumor sites completed the EORTC core questionnaire, QLQ-C30, the OUT-PATSAT35 RT, the Oberst patients' perception of care quality and satisfaction scale (OS) and the item on intention to recommend the hospital (IR). Psychometric evaluation of the structure, reliability and validity of the questionnaire was conducted. RESULTS: Multitrait-scaling analysis showed that 33 out 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 (0.70-0.97) for all scales except environment. Correlations between the areas of the QLQ-C30 and OUT-PATSAT35 RT were generally low (<0.40). Correlations between the OS and the IR were moderate with the EORTC OUT-PATSAT35 RT. Areas whose contents were more related had higher correlation coefficients (>0.50), and vice versa (<0.20). Patients with higher scores on the OS and the IR, patients who had more visits to the doctor and patients who had a better performance status showed higher SC levels in 12, 8 and 1 OUT-PATSAT35 RT areas, respectively. CONCLUSIONS: The OUT-PATSAT35 RT appears to be 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.

The EORTC cancer in-patient satisfaction with care questionnaire: EORTC IN-PATSAT32 Validation study for Spanish patients.

OBJECTIVES: The EORTC Quality of Life (QL) Group has developed a questionnaire (the EORTC IN-PATSAT32) to assess the satisfaction of cancer inpatients with hospitalbased care. In this study we assess the psychometric properties of the EORTC IN-PATSAT32 applied to a sample of Spanish patients. MATERIALS AND METHODS: Eighty cancer patients with different tumour sites completed the EORTC QLQ-C30 and EORTC IN-PATSAT32 questionnaires. Psychometric evaluation of the structure, reliability and validity was conducted. RESULTS: Multitrait scaling analysis showed that most itemscale correlation coefficients met the standards of convergent and discriminant validity. Cronbach's coefficients were good (0.77-0.97) for all scales except hospital access. Correlations between the scales and single items of the QLQ-C30 and EORTC IN-PATSAT32 were generally low. Correlations between the Oberst scales and an item on intention to recommend the hospital or ward to others with the EORTC IN-PATSAT32 were moderate. Patients with higher scores on the Oberst scales and the item on intention to recommend the hospital or ward showed higher satisfaction with care levels in all EORTC IN-PATSAT32 areas but one. CONCLUSIONS: The EORTC IN-PATSAT32 appears to be 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.
