Megjegyzések:	Glioblastoma is the most common malignant central nervous system tumor. Patient outcome remains poor despite the development of therapy and increased understanding of the disease in the past decades. Glioma cells invade the peritumoral brain, which results in inevitable tumor recurrence. Previous studies have demonstrated that the extracellular matrix (ECM) is altered in gliomas and serves a major role in glioma invasion. The present study focuses on differences in the ECM composition of tumors in patients with poor and improved prognosis. The mRNA and protein expression of 16 invasion?associated ECM molecules was determined using reverse trascription?quantitiative polymerase chain reaction and immunohistochemistry, respectively. Clinical factors of patients with different prognoses was also analyzed. It was determined that age and postoperative Karnofsky performance score were associated with patient survival. Furthermore, Fms?related tyrosine kinase 4/vascular endothelial growth factor receptor 3 (FLT4/VEGFR3), murine double minute 2 (MDM2) and matrix metallopeptidase 2 (MMP2) mRNA levels were significantly different between the two prognostic groups. Additionally, brevican, cluster of differentiation 44, hyaluronan mediated motility receptor, integrin??V and ??1, and MDM2 protein expression were indicated to be significantly different in immunohistochemistry slides. Using the expression profile, including the invasion spectrum of the samples, it was possible to identify the prognostic group of the sample with high efficacy, particularly in cases with poor prognosis. In conclusion, it was determined that ECM components exhibit different expression levels in tumors with different prognoses and thus the invasion spectrum can be used as a prognostic factor in glioblastoma.

Previous research has proved the pivotal role ofthe changes in the extracellular matrix (ECM) in cancer cell invasion.MATERIALS AND METHODS: The mRNA expression of 40 ECM molecules was determinedusing qRT-PCR in 54 fresh-frozen glioblastoma and brain metastasis samples.Seventy-two samples were used to determine the levels of 20 ECM proteins.RESULTS: The mRNA and protein expression pattern of the studied tumors differsgreatly. Linear discriminant analysis of mRNA expression identified samples basedon their mRNA expression profile with 92.3% probability and highlighted the role of some molecules as their level greatly influenced sample identification.CONCLUSION: Different tumor types with different invasiveness differ in thecomposition of their ECM and this can be used to identify samples. Furthermore,some ECM molecules greatly contribute to tumor invasiveness and could be targets of anti-invasive oncotherapy.Copyright? 2017, International Institute of Anticancer Research (Dr. George J.Delinasios), All rights reserved.DOI: 10.21873/anticanres.11799 PMID: 28739696 [Indexed for MEDLINE]
