ObjectiveThis paper seeks to quantify the normalized expression of transcripts FOXM1*3, VEGF, CD133, and MGMT and their relation with the histopathological and molecular diagnosis and with the probability of estimating tumor progression-free survival of gliomas. MethodsA cohort of patients was made up of patients aged over 18 years with a histological and molecular diagnosis of gliomas from the year 2011 to 2018. The patients had a complete tumor resection. Patients with high-grade glioma received adjuvant management (temozolamide and radiotherapy). Clinical and imaging follow-up was carried out periodically to identify the time of progression free survival (PFS). ResultsNinety-one patients (age range, 18-85 years) comprised the study cohort with a predominance of males. The expression of FOXM1*3, VEGF, and CD133 allowed the differentiation of astrocytomas grade II from GBM. ROC curves proved statistically significant in the GBM model (p < 0.05), demonstrating greatest sensitivity with FOXM1*3 (91%), and greatest specificity with VEGF (93%). The age-adjusted Cox multivariate model established that a PFS50% of 25 months corresponds to a median value of 5.3 for VEGF and 0.42 for CD133. ConclusionsThe normalized expression of transcripts FOXM1*3, VEGF, and CD133 allow us to estimate the probability of PFS, especially in gliomas grades II and IV; likewise, their overexpression defines the diagnosis of GBM.
