Cancer patients may experience a decrease in cognitive functioning before, during and after cancer treatment. So far, the Quality of Life Group of the European Organisation for Research and Treatment ...of Cancer (EORTC QLG) developed an item bank to assess self-reported memory and attention within a single, cognitive functioning scale (CF) using computerized adaptive testing (EORTC CAT Core CF item bank). However, the distinction between different cognitive functions might be important to assess the patients' functional status appropriately and to determine treatment impact. To allow for such assessment, the aim of this study was to develop and psychometrically evaluate separate item banks for memory and attention based on the EORTC CAT Core CF item bank. In a multistep process including an expert-based content analysis, we assigned 44 items from the EORTC CAT Core CF item bank to the memory or attention domain. Then, we conducted psychometric analyses based on a sample used within the development of the EORTC CAT Core CF item bank. The sample consisted of 1030 cancer patients from Denmark, France, Poland, and the United Kingdom. We evaluated measurement properties of the newly developed item banks using confirmatory factor analysis (CFA) and item response theory model calibration. Item assignment resulted in 31 memory and 13 attention items. Conducted CFAs suggested good fit to a 1-factor model for each domain and no violations of monotonicity or indications of differential item functioning. Evaluation of CATs for both memory and attention confirmed well-functioning item banks with increased power/reduced sample size requirements (for CATs greater than or equal to 4 items and up to 40% reduction in sample size requirements in comparison to non-CAT format). Two well-functioning and psychometrically robust item banks for memory and attention were formed from the existing EORTC CAT Core CF item bank. These findings could support further research on self-reported cognitive functioning in cancer patients in clinical trials as well as for real-word-evidence. A more precise assessment of attention and memory deficits in cancer patients will strengthen the evidence on the effects of cancer treatment for different cancer entities, and therefore contribute to shared and informed clinical decision-making.

During the end of life (EOL) phase of high-grade glioma (HGG) patients, care is primarily aimed at reducing symptom burden while maintaining quality of life as long as possible. In this study, we ...evaluated the prevalence of symptoms and medication management in HGG patients during the EOL phase. We analyzed disease-specific symptoms, general EOL symptoms, symptom frequency, and medication use at 3 months and 1 week before death in a cohort of 178 HGG patients, based on questionnaires completed by physicians responsible for EOL care. In addition, information on patient’s perceived quality of care (QOC) was derived from 87 questionnaires completed by patient’s relatives. Somnolence, focal neurological deficits and cognitive disturbances were the most prevalent symptoms during the EOL phase. Overall, disease-specific symptoms occurred more often than general EOL symptoms at both 3 months and 1 week before death. Somnolence and/or dysphagia were present in 81 % of patients whose medication was withdrawn and 96 % of patients in whom antiepileptic drugs (AEDs) were withdrawn. One week before death, 65.9 % of patients with high symptom frequency experienced good QOC, compared to 87.5 % of patients with low symptom frequency (
p
= 0.032). Disease-specific symptoms are the main concern in EOL care for HGG patients. Somnolence and dysphagia may hamper the regular oral administration of drugs, and particularly AEDs, during the EOL phase. High symptom frequency at 1 week before death negatively affects patient’s perceived QOC.
To assess the applicability of perfusion-weighted (PWI) magnetic resonance (MR) imaging in clinical practice, as well as to evaluate the changes in PWI in brain metastases before and after ...stereotactic radiotherapy (SRT), and to correlate these changes to tumor status on conventional MR imaging. Serial MR images at baseline and at least 3 and 6 months after SRT were retrospectively evaluated. Size of metastases and the relative cerebral blood volume (rCBV), assessed with subjective visual inspection in the contrast enhanced area, were evaluated at each time point. Tumor behavior of metastases was categorized into four groups based on predefined changes on MRI during follow-up, or on histologically confirmed diagnosis; progressive disease (PD), pseudoprogression (PsPD), non-progressive disease (non-PD) and progression unspecified (PU). Twenty-six patients with 42 metastases were included. Fifteen percent (26/168) of all PW images could not be evaluated due to localization near large vessels or the scalp, presence of hemorrhage artefacts, and in 31% (52/168) due to unmeasurable residual metastases. The most common pattern (52%, 13/25 metastases) showed a high rCBV at baseline and low rCBV during follow-up, occurring in metastases with non-PD (23%, 3/13), PsPD (38%, 5/13) and PU (38%, 5/13). Including only metastases with a definite outcome generally showed low rCBV in PsPD or non-PD, and high rCBV in PD. Although non-PD and PsPD may be distinguished from PD after SRT using the PW images, the large proportion of images that could not be assessed due to artefacts and size severely hampers value of PWI in predicting tumor response after SRT.
To describe the disease course after the cessation of infliximab in early rheumatoid arthritis patients with disease activity score (DAS)-steered treatment and to identify predictors of persistent ...low disease activity.
In a post-hoc analysis of the BeSt study, disease activity and joint damage progression were observed in patients treated with methotrexate plus infliximab, who discontinued infliximab after achieving low disease activity (DAS ≤2.4) for 6 months. Predictors were identified using Cox regression analysis.
104 patients discontinued infliximab, of whom 77 had received infliximab plus methotrexate as initial treatment. Mean DAS at the time of infliximab cessation was 1.3, median symptom duration was 23 months and median Sharp/van derHeijde score was 5.5. The median follow-up was 7.2 years. Infliximab was re-introduced after loss of low disease activity in 48%, after a median of 17 months. The joint damage progression rate did not increase in the year after cessation, regardless of flare. After re-introduction of infliximab, 84% of these patients again achieved a DAS ≤2.4. In the multivariable model, smoking, infliximab treatment duration ≥18 months and shared epitope (SE) were independently associated with the re-introduction of infliximab: 6% of the non-smoking, SE-negative patients treated <18 months needed infliximab re-introduction.
Cessation of infliximab was successful in 52%, with numerically higher success rates in patients initially treated with infliximab. Of the 48% who flared, 84% regained low disease activity. The joint damage progression rate did not increase in the year after cessation. Smoking, long infliximab treatment duration and SE were independently associated with re-introduction of infliximab.
Background
When glioma patients experience long-term seizure freedom the question arises whether antiepileptic drugs (AEDs) should be continued. As no prospective studies exist on seizure recurrence ...in glioma patients after AED withdrawal, we evaluated the decision-making process to withdraw AEDs in glioma patients, and seizure outcome after withdrawal.
Methods
Patients with a histologically confirmed low grade or anaplastic glioma were included. Eligible patients were seizure free ≥ 1 year from the date of last antitumor treatment, or ≥ 2 years since the last seizure when seizures occurred after the end of the last antitumor treatment. Patients and neuro-oncologists made a shared decision on the preferred AED treatment (i.e. AED withdrawal or continuation). Primary outcomes were: (1) outcome of the shared decision-making process and (2) rate of seizure recurrence.
Results
Eighty-three patients fulfilled all eligibility criteria. However, in 12/83 (14%) patients, the neuro-oncologist had serious objections to AED withdrawal. Therefore, 71/83 (86%) patients were analyzed; In 46/71 (65%) patients it was decided to withdraw AED treatment. In the withdrawal group, 26% (12/46) had seizure recurrence during follow-up. Seven of these 12 patients (58%) had tumor progression, of which three within 3 months after seizure recurrence. In the AED continuation group, 8% (2/25) of patients had seizure recurrence of which one had tumor progression.
Conclusion
In 65% of patients a shared decision was made to withdraw AEDs, of which 26% had seizure recurrence. AED withdrawal should only be considered in carefully selected patients with a presumed low risk of tumor progression.
Exploring cross-national differences is useful to evaluate whether different patterns of end of life (EOL) care meet patient’s specific needs. This study aimed to (1) compare EOL care processes for ...high-grade glioma (HGG) patients in three European countries, (2) explore differences in perceived quality of care (QOC), and (3) identify aspects of good QOC in the EOL phase. We analyzed 207 questionnaires from relatives of deceased HGG patients, using a similar retrospective study design in three countries The Netherlands (n = 83), Austria (n = 72) and the UK (n = 52), and examined four subthemes: (1) organization of EOL care, (2) treatment preferences, (3) experiences with EOL care, (4) perceived QOC. Three months before death 75 % of patients were at home. In all countries, on average, 50 % were transferred to a hospital at least once and received effective symptom treatment during the last 3 months. In The Netherlands, Austria and UK, respectively, patients most often died at home (60 %), in a hospital (41 %) or hospice (41 %) (
p
< 0.001). Advance directives were present in 46 % of Dutch, 36 % of British and 6 % of Austrian patients (
p
< 0.001). Fifty-three percent of patients experienced good QOC, irrespective of country. Dying at the preferred place, satisfaction with information provided and effective symptom treatment were independently associated with good QOC. There are various cross-national differences in organization and experiences with EOL care for HGG, but patient’s perceived QOC is similar in the three countries. As symptom treatment was considered effective in only half of HGG patients, and independently predicted good QOC, this particularly needs further improvement in all countries.
The impact of rituximab on health-related quality of life (HRQoL) in primary central nervous system lymphoma patients is not well known. We determined the impact of rituximab added to standard ...high-dose methotrexate-based treatment on HRQoL in patients in a large randomised trial.
Patients from a large phase III trial (HOVON 105/ALLG NHL 24), randomly assigned to receive standard chemotherapy with or without rituximab and followed by 30 Gy whole brain radiotherapy (WBRT) in patients ≤60 years, completed the EORTC QLQ-C30 and QLQ-BN20 questionnaires before and during treatment, and up to 24 months of follow-up or progression. Differences between treatment arms over time in global health status, role functioning, social functioning, fatigue, and motor dysfunction were assessed. Differences ≥10 points were deemed clinically relevant. The effect of WBRT on HRQoL was analysed in irradiated patients.
A total of 160/175 patients eligible for the HRQoL study completed at least one questionnaire and were included. Over time, scores improved statistically significantly and were clinically relevant in both arms. Between arms, there were no differences on any scale (range: −3.8 to +4.0). Scores on all scales were improved to a clinically relevant extent at 12 and 24 months compared with baseline in both arms, except for fatigue and motor dysfunction at 12 months (−7.4 and −8.8, respectively). In irradiated patients (n = 59), scores in all preselected scales, except motor dysfunction, remained stable up to 24 months compared with shortly after WBRT, overall mean difference ranging between 0.02 and 4.570.
Compared with baseline, treatment resulted in improved HRQoL scores. The addition of rituximab to standard chemotherapy did not impact HRQoL over time. WBRT did not result in deterioration of HRQoL in the first 2 years.
•HRQoL scores improved significantly and were clinically relevant from baseline, up to 2 years after treatment in PCNSL patients.•The addition of rituximab to standard high-dose methotrexate-based chemotherapy did not impact HRQoL scores in PCNSL patients.•After whole brain radiotherapy, HRQoL scores remained stable, up to 2 years after treatment.
Objective
To evaluate rheumatologists’ adherence to a low Disease Activity Score (DAS)–steered treat‐to‐target (T2T) strategy in treatment of patients with rheumatoid arthritis (RA) and to assess ...associated conditions.
Methods
Data of the BeSt study were used, a multicenter T2T strategy trial with 10‐year followup. During 3 monthly visits, the physician answered questions about satisfaction with level of RA suppression, agreement with the study protocol, and agreement with the DAS. Associations between the answers and nonadherence were evaluated.
Results
Protocol adherence decreased over time from 100% to 60% per visit, with an average over time of 79%. Rheumatologists mostly agreed with the DAS (80–90% of visits over time) and were satisfied with the treatment steps (75–90%) and with the level of RA suppression (85–90%). The odds for protocol violation were higher when the rheumatologist disagreed with the DAS (odds ratio OR 2.3, 95% confidence interval 95% CI 2.0–2.7 when they thought the DAS overestimated actual disease activity; OR 2.5, 95% CI 2.0–3.1 when they thought the DAS underestimated actual disease activity) or with the next required treatment step (OR 3.0, 95% CI 2.5–3.5), and when the physician was dissatisfied with disease suppression (OR 1.3, 95% CI 1.1–1.6).
Conclusion
Rheumatologists generally agreed with and followed a 10‐year followup DAS‐steered T2T strategy. Disagreement with the DAS or the required treatment and dissatisfaction with the level of disease suppression were risk factors for nonadherence. These results indicate the feasibility of continued protocol‐driven T2T therapy. For daily practice, adherence to T2T therapy might be improved by adopting the structure components of a clinical trial.
Several prediction models for rapid radiological progression (RRP) in the first year of rheumatoid arthritis have been designed to aid rheumatologists in their choice of initial treatment. The ...association was assessed between RRP and disability and joint damage progression in 8 years.
Patients from the BeSt cohort were used. RRP was defined as an increase of ≥5 points in the Sharp/van der Heijde score (SHS) in year 1. Functional ability over 8 years, measured with the health assessment questionnaire (HAQ), was compared for patients with and without RRP using linear mixed models. Joint damage progression from years 1 to 8 was compared using logistic regression analyses.
RRP was observed in 102/465 patients. Over 8 years, patients with RRP had worse functional ability: difference in HAQ score 0.21 (0.14 after adjustment for disease activity score (over time)). RRP was associated with joint damage progression ≥25 points in SHS in years 1-8: OR 4.6.
RRP in year 1 is a predictor of worse functional ability over 8 years, independent of baseline joint damage and disease activity. Patients with RRP have more joint damage progression in subsequent years. RRP is thus a relevant outcome on which to base the initial treatment decision.
