Immunotherapeutic Approaches for the Treatment of Glioblastoma Multiforme: Mechanism and Clinical Applications.

ABSTRACT: Glioma is one of the most aggressive types of primary brain tumor with a high-grade glioma known as glioblastoma multiforme (GBM). Patients diagnosed with GBM usually have an overall survival rate of less than 18 months after conventional therapy. This bleak prognosis underlines the need to consider new therapeutic interventions for GBM treatment to overcome current treatment limitations. By highlighting different immunotherapeutic approaches currently in preclinical and clinical trials, including immune checkpoint inhibitors, chimeric antigen receptors T cells, natural killer cells, vaccines, and combination therapy, this review aims to discuss the mechanisms, benefits, and limitations of immunotherapy in treating GBM patients.

Project description:Liver cancer, the most common form of which is hepatocellular carcinoma (HCC), is one of the most deadly cancers worldwide. As of 2008, in men, HCC was the fifth most common cancer (approximately 450,000 new cases per year) and the second most frequent cause of death from cancer (around 416,000 deaths per year), whereas in women, it was the seventh most frequently diagnosed cancer (150,000 new cases per year) and the sixth most frequent cause of cancer deaths (140,000 deaths per year) [1]. Overall, HCC is the third leading cause of death from cancer globally [2, 3]. Worldwide, the incidence of HCC in males is more than twice that in females. The etiology of HCC is diverse; however, approximately 80% of HCCs occur secondary to chronic infection with hepatitis B virus (HBV) and/or hepatitis C virus (HCV) [4]. The geographic distribution of HCC is such that the high-incidence regions of Eastern Asia and sub-Saharan Africa bear a disproportionate HCC burden, amounting to more than 80% of the global burden [4]. However, even in areas considered low-incidence regions-North America and Europe-the incidence of HCC is on the rise [4]. In the US, HCC incidence has risen more than threefold in the past 30 years, and it is now the ninth most frequent cause of death from cancer. The major reasons for the increased incidence of HCC in the US are the increasing prevalence of chronic HCV infection, increased immigration from high-incidence countries in Asia and Africa, and the increase in the number of individuals with cirrhosis due to obesity-related fatty liver disease. Most HCCs are diagnosed at an advanced stage for which there is no curative option. Sorafenib, the only agent specifically approved for HCC treatment, is of limited efficacy in this setting. Therefore, an urgent need for improved HCC therapy exists. In this review, we discuss the available data on the development and use of immunotherapy for HCC, with a particular focus on recent results and novel approaches.

Project description:Congenital glioblastoma multiforme (cGBM) historically has been considered an aggressive tumor of infancy requiring extensive chemotherapy to achieve cure. We report on 4 patients at our institution with cGBMs who were treated with surgery and chemotherapy (carboplatin and etoposide every 21 days for 2-6 cycles). Four of four patients are progression free at a median time of 27.5 months (22-103 months). To characterize the molecular biology of cGBM, we compared the gene expression profiles of 3 cGBMs to 12 pediatric and 6 primary adult glioblastomas collected at our institution. Unsupervised hierarchical clustering showed cGBMs grouped together with other high-grade gliomas. cGBMs demonstrated marked similarity to both pediatric and adult GBMs, with only a total of 31 differentially expressed genes identified (FDR < 0.05). Unique molecular features of congenital GBMs identified included over-expression of multiple genes involved in glucose metabolism and tissue hypoxia pathways. Four tyrosine kinases were also mong the up-regulated genes (RET, RASGRF2, EFNA5, ALK). Thus, at our institution congenital GBMs, while similar both histologically and molecularly to other GBMs, appear to have a good prognosis with surgery in combination with relatively moderate chemotherapy. Further study is needed to determine if the few gene expression differences that were identified may contribute to the better survival seen in these tumors compared to pediatric or adult GBMs. Key Words: glioblastoma; congenital; pediatric; gene expression; microarray Molecular profiling of 18 AT/RT patient tumor samples was performed using Affymetrix U133 Plus2 GeneChips. Data were background corrected and normalized using gcRMA (as implemented in Bioconductor). Unsupervised agglomerative hierarchical clustering was performed to identify subsets of AT/RTs with similar gene expression. Limma (moderated t-tests; Bioconductor) was used to identify signature genes for each cluster. Bioinformatics web tool DAVID was used to identify enriched biological processes for each cluster. Survival was analyzed using Kaplan-Meier curves and Cox Hazard Ratio. Bioinformatics tools Gene Set Enrichment (GSEA) and Ingenuity Pathways Analysis were also used to gain further insight into cluster differences.
