The most recent developments in diagnostic and therapeutic aspects of gliomas (glioblastoma) in the brain are presented. The importance of personalized medicine and clinical validation for targeted therapy are discussed. The identification of various types of biomarkers (determined by molecular genetics) is included, along with their advantages and limitations as markers in tumor detection and diagnosis. The identification and validation of brain cancer (glioblastoma) genes are discussed. The role of cancer stem cells in the initiation and persistence of malignant gliomas is explained, response of glioblastoma cancer stem cells to various growth factors, such as epidermal growth factor receptor kinase inhibitor, is explained. The use of surgical resection, chemotherapy (e.g., temozolomide), immunotherapy, and radiation therapy for glioblastoma patients is included. Biological impediments for chemotherapy and radiotherapy for malignant glioblastoma are pointed out. Standard (established) as well as newer imaging modalities (proton magnetic resonance spectroscopy) are discussed. Also included are proton magnetic resonance spectroscopy in intracranial gliomas, and the use of proton magnetic spectroscopic imaging in determining the infiltration zone in gliomas. The role of molecular signaling in the CNS cancer development is explained, including cell death signaling in glioblastoma multiforme.

Latar Belakang : Inflamasi kronik berhubungan dengan tumor dan menyebabkan prognosis yang buruk pada pasien kanker. Salah satu penanda inflamasi yang meningkat pada tumor adalah C-Reactive Protein (CRP). Kadar CRP meningkat pada lebih dari 50% pasien keganasan. Peningkatan CRP berhubungan kuat dengan keparahan penyakit pada beberapa kanker. Salah satu zat gizi dalam inflamasi adalah asam lemak omega-3. Asam lemak omega-3 dapat meningkatkan pembentukan specialized pro-resolving mediators (SPM) yang berfungsi meningkatkan mediator antiinflamasi, melindungi blood brain barrier, menurunkan sitokin proinflamasi, menurunkan apoptosis neuron. Penelitian ini bertujuan untuk menilai hubungan asupan asam lemak omega-3 dengan CRP pada pasien tumor sistem saraf pusat. Metode : Studi potong lintang ini dilakukan pada subjek berusia 18-65 tahun di RSUPN Cipto Mangunkusumo pada bulan November hingga Desember 2023. Pengukuran CRP menggunakan metode immunoturbidimetric assay. Pengambilan asupan asam lemak omega-3 menggunakan Food Frequency Questionnaires semikuantitatif. Analisis bivariat digunakan untuk menilai hubungan antara variabel bebas dan terikat. Hasil : Dari total 63 subjek penelitian, sebanyak 35 subjek (55,6%) pada kelompok asupan asam lemak omega-3 < 2 g/hari dan 28 subjek (44,4%) pada kelompok asupan asam lemak omega-3 ≥ 2 g/hari. Nilai median CRP 8,3 (0,6 – 71,5) mg/L. Tidak terdapat hubungan yang bermakna (p = 0,714) antara asupan asam lemak omega-3 dengan CRP pada pasien tumor sistem saraf pusat. Kesimpulan : Tidak terdapat hubungan bermakna antara asupan asam lemak omega-3 dengan CRP pada pasien tumor sistem saraf pusat. ......Background: Chronic inflammation is associated with tumors and causes poor prognosis in tumor patients. One of the inflammatory markers that increase in tumors is C-Reactive Protein (CRP). CRP levels are elevated in more than 50% of patients with malignancies. Elevated CRP is associated with disease severity in some cancers. One of the nutrients in inflammation is omega-3 fatty acids. Omega-3 fatty acids can increase the formation of specialized pro-resolving mediators (SPM) which function to increase anti-inflammatory mediators, protect the blood brain barrier, reduce pro-inflammatory cytokines, reduce neuron apoptosis. This study aims to assess the relationship between omega-3 fatty acid intake and CRP in patients with central nervous system tumors. Methods: This cross-sectional study was conducted on subjects aged 18-65 years at Cipto Mangunkusumo Hospital from November to December 2023. CRP measurement using immunoturbidimetric assay method. Omega-3 fatty acid intake was collected using semiquantitative Food Frequency Questionnaire. Bivariate analysis was used to assess the relationship between independent and dependent variables. Results: From the total 63 research subjects, 35 subjects (55,6%) in the omega-3 fatty acid intake group < 2 g/day and 28 subjects (44,4%) in the omega-3 fatty acid intake group ≥ 2 g/day. The median CRP value was 8.3 (0.6 - 71.5) mg/L. There was no significant relationship (p = 0,714) between omega-3 fatty acid intake and CRP in patients with central nervous system tumors. Conclusion: There is no significant relationship between omega-3 fatty acid intake and CRP in patients with central nervous system tumors.
