This population-based study supports the importance of surgery instead of biopsy only, followed by radiotherapy and chemotherapy, a finding which has also been stated in earlier non-population-based reports. However, it is obvious that the solution is not just surgical radicality followed by optimal oncological treatment. It is of great importance to seek further subclassifications, biomarkers, and new treatment modalities to make a significant change in survival for individuals.
Purpose
The health-related quality of life (HRQoL) for patients with glioblastoma is known to be largely affected. Little is known about the HRQoL for relatives and the relationship between these two. To optimize family care, such issues need to be addressed early on, preferably from the time of diagnosis. This study aimed to describe and compare the HRQoL of patients with glioblastoma and their relatives before surgery.
Methods
A prospective cohort study including 89 patients diagnosed with glioblastoma and their relatives. HRQoL (Short Form Health Survey, SF-36) and emotional well-being (hospital anxiety and depression scale, HADS) were analysed with descriptive, comparative and multivariable regression analyses.
Results
Relatives scored worse for mental HRQoL (p < 0.001) and for symptoms of anxiety (p < 0.001) and depression (p = 0.022) compared to patients. The multivariable regression showed an increased risk of affected mental HRQoL in relatives of patients with poor functional status (WHO) (p = 0.01) and higher levels in symptoms of anxiety (p = 0.03), or when relatives had low physical HRQoL themselves (p = 0.01). There was increased risk of affected mental HRQoL in patients with comorbidities (p = 0.003), and when the respective relative showed higher levels in symptoms of anxiety (p = 0.005).
Conclusion
Relatives scored worse for mental HRQoL and emotional well-being than patients, suggesting that HRQoL in patients and relatives might be connected to symptoms of anxiety in the respective individual at disease onset. The results illustrate the need to screen HRQoL and emotional well-being in both patients and relatives from an early stage—before surgery.
Purpose: We aimed to develop a diagnostic platform to capture the transcriptomic resemblance of individual adult diffuse gliomas of WHO grades II to IV to neural development and the genomic signature associated with glioma progression.Experimental Design: Based on the EM/PM classification scheme, we designed a RT-PCR-based TaqMan low-density array (TLDA) containing 44 classifier and 4 reference genes. Samples of a training dataset (GSE48865), characterized by RNA-sequencing, were utilized to optimize the TLDA design and to develop a support vector machine (SVM)based prediction model. Complemented with Sanger sequencing for IDH1/2, and low coverage whole genome sequencing (WGS), the TLDA and SVM prediction model were tested in a validation (31 gliomas) and a test (121 gliomas) dataset.Results: Independent of morphologically defined subtypes and grades, gliomas can be individually assigned into the EM and PM glioma subtypes with the respective areas under ROC curves at 0.86 and 0.85 in the validation dataset. The EM gliomas showed a medium overall survival (OS) of 15.6 months, whereas the medium OS for PM gliomas was not reached (HR ¼ 3.55; 95% confidence interval, 1.96-6.45). The EM and PM gliomas showed distinct patterns of genomic alterations, with IDH mutation and 1p19q codeletion in the PM gliomas and gain of chromosome 7/loss of chromosome 10 in the EM gliomas. Extensive chromosomal abnormalities marked the progression of PM gliomas.Conclusions: The integration of EM/PM subtyping, IDH sequencing, and low coverage WGS may improve the risk stratification and selection of treatment regimens for patients with glioma.
Background Elderly patients with glioblastoma and an accumulation of negative prognostic factors have an extremely short survival. There is no consensus on the clinical management of these patients and many may escape histologically verified diagnosis. The primary aim of this study was to characterize this particular subgroup of patients with radiological glioblastoma diagnosis without histological verification. The secondary aim was to evaluate if oncological therapy was of benefit. Methods Between November 2012 and June 2016, all consecutive patients presenting with a suspected glioblastoma in the western region of Sweden were registered in a population-based study. Of the 378 patients, 131 (35%) met the inclusion criteria of the present study by typical radiological features of glioblastoma without histological verification. Results The clinical characteristics of the 131 patients (72 men, 59 women) were: age � 75 (n = 99, 76%), performance status according to Eastern Cooperative Oncology Group � 2 (n = 93, 71%), significant comorbidity (n = 65, 50%) and multilobular tumors (n = 90, 69%). The overall median survival rate was 3.6 months. A subgroup of 44 patients (34%) received upfront treatment with temozolomide, with an overall radiological response rate of 34% and a median survival of 6.8 months, compared to 2.7 months for those receiving best supportive
