Isocitrate dehydrogenaseCwild-type tumors were more likely to have a nondefinable border, while isocitrate dehydrogenaseCmutant tumors experienced well-defined borders (66.7% vs 39.1%, = .0287). Only 8 (17.4%) of 46 of the isocitrate dehydrogenaseCmutant tumors demonstrated marked enhancement, while this was 66.7% in isocitrateCwild-type tumors ( .0001). CholineCcreatinine ratio for isocitrate dehydrogenaseCwild-type tumors was significantly higher than that for isocitrate dehydrogenaseCmutant tumors. In conclusion, frontal location, well-defined border, cortical involvement, less peritumoral edema, lack of enhancement, and low cholineCcreatinine ratio were predictive for the definition of isocitrate dehydrogenaseCmutant low-grade gliomas. Magnetic resonance imaging can provide an advantage in the detection of isocitrate dehydrogenase status indirectly and show the need to explore new design for treatment planning in gliomas. CholineCcreatinine ratio in magnetic resonance spectroscopy could be a potential more reasonable reference for the new design of delineation of target volume in low-grade gliomas. test for continuous variables. Receiver operating characteristic (ROC) analysis and binary logistic regression were plotted to evaluate diagnostic power including the areas under the curve (AUC). Diagnostic power is usually displayed in Rabbit Polyclonal to SENP8 terms of SEN, specificity (SPE), positive predictive value (PPV), unfavorable predictive value (NPV), and accuracy (ACC). Statistical analysis was conducted using SPSS (version 19.0.0; SPSS Inc, Chicago, Illinois) and GraphPad (MedCalc Inc, Mariakerke, Belgium). values of .05 were considered statistically significant. Results Patient Demographics As exhibited in Table?1, 76 cases (48 males and 28 females, age 39 10.2 years) were diagnosed as LGG based on the current WHO criteria. Isocitrate dehydrogenase mutation statue, MGMT promoter methylation status, and 1p/19q co-deleted were based on the current WHO criteria. Magnetic resonance spectroscopy combined with cMRI were performed, and 72 of 76 patients evaluated MRS. Table?1 shows the summary of the main clinical and cMRI features between the groups (IDH-MT/IDH-WT).

No significant difference in TERT mutation was seen between the 2 groups (= .2229). Ki-67 value of tumors was also analyzed, and no significant correlation was noted between the 2 groups (= .5454).

It seemed purchase Phloridzin that peritumoral edema was less frequent in IDH-MT tumors (32.6% vs 58.3% for tumors with IDH-WT tumors, = .0381). Isocitrate dehydrogenase-WT tumors were more likely to have a nondefinable border, while IDH-MT tumors experienced well-defined borders (66.7% vs 39.1%). There was significant difference in contrast enhancement between the 2 groups ( .0001). In fact, only 8 purchase Phloridzin (17.4%) of 46 IDH-MT tumors in this study demonstrated marked enhancement, while this was 66.7% in WT tumors. There was a pattern toward lower frequency of cystic switch in IDH-WT tumors that did not meet statistical significance (= .8042). Open in a separate window Physique?1.
