Introduction: Astrocytic gliomas are the most common and lethal intracranial brain tumours and rely on angiogenesis for the tumour development. Endothelial progenitor cells (EPCs) contribute to the angiogenesis of glioma tumour. Objectives: The study aimed to investigate the matured circulating endothelial cells population in the peripheral blood mononuclear cells (PBMCs) and its associations with tissue resident angiogenic cells in astrocytic glioma patients. Methods: A total of 22 astrocytic glioma patients were recruited from Hospital Universiti Sains Malaysia. Tumour were sliced and stained with CD133+ and VEGFA+ for angiogenic cells (n=22). The circulating (CD133-/VEGFR2+) matured endothelial cells in PBMCs (n=22) were quantified using FACS. The paired t-test and Pearson correlation test were used for the data analysis. Results: The angiogenic cells in brain tumour tissue were significantly higher compared to adjacent normal brain tissue (median 1.07±0.96% vs. median 0.69±0.68%; Wilcoxon signed rank test Z=-3.100; p=0.002). Positive correlation was found between the angiogenic cells of brain tumour tissue and adjacent normal brain tissue (Spearman’s rho correlation test, r=0.56; p=0.007). Significant positive correlation was found between matured endothelial cells in peripheral circulating systems and angiogenic cells in tumour of astrocytic glioma patients (Pearson correlation test, r=0.60, p=0.003).Conclusion:The findings of the study give support to the possible roles of EPCs in astrocytic glioma patients. Thus targeting tissue resident angiogenic cells and matured circulating endothelial cells by antiangiogenic treatment might be useful to prevent the tumour growth.
Astrocytic gliomas are the most common primary brain tumours that originated from human glial cells. The tumours rely upon endothelial progenitor cells (EPCs) for neoangiogenesis. This study aimed to investigate the association between tissue resident EPCs in a brain tumour and normal adjacent tissue in relation to age and grade of astrocytic glioma. Astrocytic glioma patients (n=22), grade I to grade IV were consented from Hospital Universiti Sains Malaysia. Brain tumour tissue and normal adjacent brain tissue samples were obtained from each patient during surgery. The EPCs were stained with CD133+ and VEGFR-2+ markers. The tissue residents EPCs for each sample were determined using the immunofluorescence microscopy method. The age of the patients increased by disease severity in the following order (Grade I: 21.33±20.79 years) < (Grade II: 46.50±0.707 years) < (Grade III: 47.38±11.95 years) < (Grade IV: 48.44 ±10.66 years). The EPCs in brain tumour correlated significantly with the age of the patients with positive correlation (Spearman’s rho correlation test, r=0.52; p=0.013). The tissue resident EPCs in the brain tumour (median=0.40, IqR=0.59) were significantly higher compared with the adjacent normal brain (median=0.067, IqR=0.29) (Wilcoxon Signed-Rank Test, Z stat=-3.587, p
Background: This paper investigates the quality of life of brain pathology patients in relation to their sociodemographic
profiles and clinical factors.
Methods: This is a cross-sectional study done at a tertiary referral hospital in Kuala Lumpur. A total of 100
patients were recruited in the study after excluding 22 patients who did not met the exclusion criteria. The
European Organisation for Research and Treatment of Cancer Quality of Life (EORTC QLQ-C30) self-administered
questionnaire was utilized in the study. The Global health status/QoL, Physical functioning, Role functioning,
Emotional functioning, Cognitive functioning, Social functioning, Fatigue, Nausea and vomiting, Pain, Dyspnoea,
Insomnia, Appetite loss, Constipation, Diarrhoea, and Financial difficulties were assessed in this study.
Results: The most severe impairment in functioning was with lowest score of cognitive functioning (mean
score=61) and the most severe symptom was fatigue (mean score=45). There were significant differences in
quality of life scores in different socio-demographic groupsand types of brain pathology patients. Patients aged
below 40 years old or less had better physical functioning, less symptoms of fatigue and insomnia compared
to patients who were more than 40 years old. Male patients faced more financial difficulties compared with
female patients. Patients who were married had increased insomnia compared to the single patients. Employed
patients had better physical functioning and less financial difficulties compared with patients who were
unemployed. Patients who earned >RM 2500.00 monthly had better physical functioning, less symptoms of pain and less financial difficulties than patients who earned ≤RM 2500.00. Patients with qualifications lower
than SPM tended to face more financial difficulties compared to patients with qualifications of SPM or higher.
Meningioma patients had better social functioning compared with others, whereas Carvenoma patients had
better physical functioning. Meningioma patients had more symptoms of insomnia compared with other
patients. All the findings were with p value less than 0.05.
Conclusion: The quality of life of patients with brain pathology is affected by socio-demographic factors and
clinical diagnoses. Efforts should be made to improve the overall quality of life of these patients.
The objective of this study was to determine the prevalence of symptoms and problems in Malaysian brain pathology patients. A total of 100 respondents in Kuala Lumpur Hospital were included in this cross-sectional study. The study utilized European Organization for Research and Treatment of Cancer Quality Of Life questionnaire (EORTC QLQ-C30). Patient with a “symptom/problem” having the minimum response of “a little”. A response of “quite a bit” was defined as having a “severe symptom/problem”. The two most prevalent “symptoms/problems” among the neurological disorder patients were fatigue (65%; severe: 28%) and reduced cognitive functioning (64%; severe: 25%). The mean number of “symptoms/problems” ranged from 4.63 (meningioma) to 6.80 (cerebellar edema) while the mean number of “severe symptoms/problems” ranged from 1.39 (astrocytic glioma) to 2.8 (cerebellar edema). Therefore special attention should be given to these patients in order to improve the overall quality of life of the patients.
