Health-related quality of life of long-term high-grade glioma survivors

The objective of this study was to compare the health-related quality of life (HRQOL) of long-term to short-term high-grade glioma (HGG) survivors, determine the prognostic value of HRQOL for overall survival, and determine the effect of tumor recurrence on HRQOL for long-term survivors. Following baseline assessment (after surgery, before radiotherapy), self-perceived HRQOL (using the Medical Outcomes Study Short Form 36 [SF-36]) and brain tumor-specific symptoms (using the 20-item Brain Cancer Module) were assessed every 4 months until 16 months after histological diagnosis. Kaplan-Meier survival analysis and the Cox proportional hazards model were performed to estimate overall survival of patients with impaired scores on the aggregated SF-36 higher-order summary scores measuring physical functioning on a physical component scale and on a mental component scale (MCS). Sixteen patients with a short-term survival (baseline and 4-month follow-up) and 16 with a long-term survival (follow-up until 16 months after diagnosis) were selected out of 68 initially recruited HGG patients. At baseline, the short-term and long-term survivors did not differ in their HRQOL. Between baseline and the 4-month follow-up, HRQOL of short-term survivors deteriorated, whereas the long-term survivors improved to a level comparable to healthy controls. Patients with impaired mental functioning (MCS) at baseline had a shorter median survival than patients with normal functioning. After accounting for differences in patient and tumor characteristics, however, mental functioning was not independently related to poorer overall survival. Not surprisingly, in the group of long-term survivors, the five patients with recurrence had a more compromised HRQOL at the 16-month follow-up compared to the 11 patients without recurrence. We concluded that baseline HRQOL is not related to duration of survival and that long-term survivors show improvement of HRQOL to a level comparable to that of the healthy

Treatment of early rheumatoid and undifferentiated arthritis

This thesis focuses on different aspects of treatment of patients with rheumatoid arthritis (RA) and undifferentiated arthritis (UA), based on the results of three intervention studies; the IMPROVED-study, the BeSt study and the PROMPT study. This thesis discusses the results of different treatment strategies for patients with RA and UA; the percentage of patients that achieves remission , the mean disease activity, radiographic damage progression and daily functioning. I then analysed the factors that effect the response to treatment and the achievement of drug free remission . Then radiological damage progression is discussed. Are there patients with early arthritis who have rapid radiographic progression in the first year after diagnosis or we can prevent this with effective treatment? We also assessed whether patients with early RA have metacarpal bone mineral density loss after 4 months, measured with digital X-ray radiogrammetry, and whether this predicts radiological damage progression after 1 year of anti-rheumatic treatment. Finally , I analyzed how the IMPROVED population was doing with regard to psychological well-being (mood and optimism), quality of life and the relationship of these so-called patient-reported outcomes with disease activity and achievement of remission.The research was financially supported by AbbVie, the Dutch Arthritis Foundation, the Netherlands Organisation for Scientific Research, the Dutch College for Health Insurances, Janssen Biologics B.V. and Schering-Plough B.V.

Multicenter phase II trial of temozolomide in patients with glioblastoma multiforme at first relapse

Background: Recurrent glioblastoma multiforme (GBM) is resistant to most therapeutic endeavors, with low response rates and survival rarely exceeding six months. There are no clearly established chemotherapeutic regimens and the aim of treatment is palliation with improvement in the quality of life. Patients and methods: We report an open-label, uncontrolled, multicenter phase II trial of temozolomide in 138 patients (intent-to-treat [ITI] population) with glioblastoma multiforme at first relapse and a Karnofsky performance status (KPS) ≥ 70. One hundred twenty-eight patients were histologically confirmed with GBM or gliosarcoma (GS) by independent central review. Chemotherapy-naïve patients were treated with temozolomide 200 mg/m2/day2/day orally for the first five days of a 28-day cycle. Patients previously treated with nitrosourea- containing adjuvant chemotherapy received 150 mg/m2/day for the first five days of a 28-day cycle. In the absence of grade 3 or 4 toxicity, patients on the 150 mg/m2 dose schedule were eligible for a 200 mg/m2 dose on the next cycle. Results: The primary endpoint was six-month progression-free survival assessed with strict radiological and clinical criteria. Secondary endpoints included radiological response and Health-related Quality of Life (HQL). Progression-free survival at six months was 18% (95% confidence interval (CI): 11%-26%) for the eligible-histology population. Median progression-free survival and median overall survival were 2.1 months and 5.4 months, respectively. The six-month survival rate was 46%. The objective response rate (complete response and partial response) determined by independent central review of gadolinium-enhanced magnetic resonance imaging (MRI) scans was 8% for both the ITT and eligible-histology populations, with an additional 43%;A and 45% of patients, respectively, having stable disease (SD). Objectively assessed response and maintenance of a progression-free status were both associated with HQL benefits (characterized by improvements over baseline in HQL domains). Temozolomide had an acceptable safety profile, with only 9% of therapy cycles requiring a dose reduction due to thrombocytopenia. There was no evidence of cumulative hematologic toxicity. Conclusions: Temozolomide demonstrated modest clinical efficacy, with an acceptable safety profile and measurable improvement in quality of life in patients with recurrent GBM. The use of this drug should be explored further in an adjuvant setting and in combination with other agent

Internet-based guided self-help for glioma patients with depressive symptoms: a randomized controlled trial

Depressive symptoms are common in glioma patients, and can negatively affect health-related quality of life (HRQOL). We performed a nation-wide randomized controlled trial to evaluate the effects of an online guided self-help intervention for depressive symptoms in adult glioma patients. Glioma patients with depressive symptoms were randomized to a 5-week online course based on problem-solving therapy, or a waiting list control group. After having received the intervention, the glioma patient groups combined were compared with patients with cancer outside the central nervous system (non-CNS cancer controls), who also received the intervention. Sample size calculations yielded 63 participants to be recruited per arm. The primary outcome [depressive symptoms (CES-D)] and secondary outcomes [fatigue (Checklist Individual Strength (CIS)) and HRQOL (Short Form-36)], were assessed online at baseline, post-intervention, and 3 and 12 months follow-up. In total, 89 glioma patients (intervention N = 45; waiting list N = 44) and 26 non-CNS cancer controls were included, of whom 35 and 54% completed the intervention, respectively. Recruitment could not be extended beyond 3.5 years due to funding. On depression, no statistically significant differences between the groups were found. Fatigue decreased post-treatment in the glioma intervention group compared with the waiting list group (p = 0.054, d = 0.306). At 12 months, the physical component summary (HRQOL) remained stable in glioma patients, while scores improved in non-CNS cancer controls (p = 0.035, d = 0.883). In this underpowered study, no evidence for the effectiveness of online guided self-help for depression or HRQOL in glioma patients was found, but it may improve fatigue

The role of whole-genome sequencing for guiding systemic therapy in patients with soft tissue sarcoma

Background: The analysis of tumor DNA by whole-genome sequencing (WGS) is increasingly utilized for the identification of clinically relevant DNA aberrations. We aim to assess whether WGS improves the guidance of individualized systemic therapy in soft tissue sarcoma (STS).Patients and methods: WGS results of STS patients were retrieved from electronic patient records and pathology reports from clinical studies and routine diagnostics. WGS was carried out in primary STS with an unfavorable prognosis, metastatic STS, or STS where broad molecular diagnostics were deemed necessary. Actionable targets were defined as genomic alterations identified by WGS for which specific systemic therapy was indicated in routine care or clinical trials available at time of the WGS analysis. Results: WGS was carried out on 161 STS patients. The most common histological subtypes were leiomyosarcoma (22%), undifferentiated pleomorphic sarcoma/sarcoma not otherwise specified (17%) and dedifferentiated liposarcoma (14%). The majority of WGS analyses were requested at the time of recurrence or metastasis (41%), At least one actionable target was found by WGS in 74 (46%) of patients. Actionable targets were more frequently seen for complex genome sarcomas compared with simple genome sarcomas (50% versus 28%). Eventually, 23 patients (14%) received matched experimental therapy based on their WGS results. Non-availability of WGS directed treatment or lack of clinical necessity for systemic therapy (n = 17) and rapid disease progression causing poor performance score (n = 10) were the main reasons to not start WGS-informed therapy. Conclusion: WGS identified actionable targets in 46% of STS cases, leading to WGS-informed therapy in 14% of patients. Improving the timing of the WGS request and a more appropriate patient selection upfront could increase this relatively low percentage. Complex genome sarcomas seem to be the STS group for which WGS is most likely to add value by opening the way to tumor-agnostic therapies.</p

Psychosocial determinants of adherence with oral anticancer treatment: 'we don't need no education'

INTRODUCTION: Given the potentially fatal consequences of inadequate adherence with oral anticancer treatment in persons with cancer, understanding the determinants of adherence is vital. This paper aims at identifying psychosocial determinants of adherence to oral anticancer treatment. METHODS: We reviewed the literature on psychosocial determinants of adherence with oral anticancer treatment, based on published literature in English, from 2015 to present. Literature searches were performed in PubMed, Embase, Web of Science, Cochrane library, Emcare, and PsychINFO, with 'cancer', 'medication adherence', 'psychology', and 'oral anticancer treatment' as search terms. The obtained 608 papers were screened by two independent reviewers. RESULTS: In the 25 studies identified, illness perceptions, medication beliefs, health beliefs, and depression were found to be the major psychosocial determinants of adherence to oral anticancer treatment; sociodemographic and clinical characteristics were found to be of no major importance. The quality of the identified studies as assessed by two independent reviewers was found to be acceptable overall. The majority of papers were from North America and focused on patients with breast cancer; sample size varied from 13 to 1371; adherence was assessed with questionnaires derived from various theoretical models, pill counts and electronic pharmacy records; illness perceptions reflecting adaptive coping, and medication beliefs reflecting high necessity and low concerns were found to be associated with adherence. CONCLUSION: Psychosocial concepts are major determinants of adherence with oral anticancer treatment. 'Beliefs about medicines' and 'illness perceptions' in particular determine adherence with this treatment. Studies aiming at impacting adherence would benefit from interventions with a solid basis in behavioral theory in order to help health care providers explore and address illness perceptions and medication beliefs. Pre-consultation screening of adherence behavior may be a helpful supportive approach to improve adherence. Blaming the victim ('patients should be educated about the importance of adherence') is better replaced by encouraging health professionals to identify and address maladaptive psychosocial determinants of adherence

Long-term survival of participants in the PASART-1 and PASART-2 trials of neo-adjuvant pazopanib and radiotherapy in soft tissue sarcoma

OBJECTIVE: This study aims to assess the long-term safety and efficacy of adding pazopanib to neo-adjuvant radiotherapy followed by surgery in patients with high-risk non-metastatic soft tissue sarcoma of the trunk and extremities treated in the PASART-1 and PASART-2 trials, as well as to compare the PASART cohorts to a control cohort receiving standard treatment during the same time period from the Netherlands Cancer Registry (IKNL) to investigate if adding pazopanib improves Overall Survival (OS).METHODS: Updated follow-up data on disease control, survival and long-term toxicities of the PASART-trials were extracted from electronic patient records. The effect of adding pazopanib to neo-adjuvant radiotherapy on OS was investigated by comparing the combined PASART cohorts to the IKNL cohort via direct comparison and exact matching analysis. RESULTS: PASART-trials included 34 patients, IKNL cohort included 487 patients. After a median follow-up of 75.4 months (range: 30-131 months) the 1-year, 2-year and 5-year OS in the PASART-trials were 97% (95% confidence interval [CI]: 91.5-100), 85.3% (95% CI: 74.2-98.1), 79.3% (95% CI: 66.8-94.2), respectively. Matching resulted in 23 PASART and 89 IKNL patients. Adding pazopanib did not significantly improve OS when compared to standard treatment (IKNL) in a direct comparison (hazard ratio [HR]: 0.58; 95% CI: 0.30-1.13) or matched analysis (HR: 0.70; 95% CI: 0.29-1.73). Long-term toxicities, mainly fibrosis (n = 6) and edema (n = 2), were observed in 11 PASART patients and comparable to historical controls. INTERPRETATION: The addition of pazopanib had tolerable long-term toxicity but did not improve OS when compared to a control cohort receiving standard treatment.</p
