low‐grade gliomaretinoblastomasecond cancerssurvivorshipRetinoblastoma survivors with a germline RB1 mutation are at elevated risk for secondary (nonocular) malignancy, but their risk for lowゞrade glioma (LGG) is unknown. We performed a retrospective review of the Memorial Sloan Kettering Cancer ...
Low grade gliomas (LGG) represent a heterogeneous group of grade I and II tumors as per the WHO grading system with the majority of astrocytic origin. They are the most common tumor subtype within the pediatric population. Location is influenced by age and underlying neurocutaneous syndromes (e...
such as astrocytomas, oligodendrogliomas, ependymomas, subependymomas, choroid plexus papillomas, ganglion cell tumors, and neurocytomas. Distinction of histopathologic varieties of primary brain tumors on imaging is based on tumor location and imaging features such as presence of a cyst, contrast enh...

with studies of higher-grade glioma, yet as discussed earlier, LGGs do not typically enhance, thus complicating the measurement of response to chemotherapy [64]. FLAIR and T2 signal changes often reflect the combined effect of underlying tumor and gliosis, making response assessment more difficult...
grade tumors. Nonetheless, children with low grade glioma are a therapeutic challenge due to the heterogeneity in their clinical behavior – in particular, those with incomplete surgical resection often suffer repeat progressions with resultant morbidity and, in some cases, mortality. The identification ...

Purpose: Immunohistochemical techniques were used to detect the expression of Ki-67, a nuclear proliferation marker, in 180 low-grade glioma tumor specimens to determine whether Ki-67 is a prognostic predictor of survival or tumor recurrence. Methods and Materials: A clinical database of 180 low-...
tumor group. Despite the exponential gains in molecular profiling and understanding of LGG, survival rates and treatment options have stagnated over the past few decades with few advancements. In this study, we utilize low grade glioma RNA-seq data from the Cancer Genome Atlas (TCGA-LGG) and ...
