The classification criteria for glioma patients based on age were 014years old (pediatric group) and 1547years old (youth group), 4863years old (middle-aged group) and64years old (elderly group).

Different learning machine algorithms are tested for the classification of the teenager and adult age group, and the Deep Convolutional Neural Network . C: Heatmap of middle-age group. A number of studies have showed that the tumor-prone locations, histopathology, prognosis and some molecular markers are different in glioma patients of different ages [25, 26]. 1998;55(7):9228. B: Cumulative age distribution of IDH1-wt glioma and IDH1-mut glioma. Integrated molecular genetic profiling of pediatric high-grade gliomas reveals key differences with the adult disease. According to the 2016 World Health Organization (WHO) classification of tumors of the CNS, gliomas were classified into four grades (WHO grade I to IV) based on histologic criteria [3].

Patterns of care and outcomes among elderly individuals with primary malignant astrocytoma. This age group classification will help to improve the diagnosis, personalized treatment, and clinical trial design involved patients with glioma. J Endod 45:91722 e5. Age-related studies involving a large number of glioma patients have yielded some relevant results [21, 22], but the age grouping criteria for these studies are influenced by several clinical factors, such as the tendency of clinical researchers. Life expectancy at age 60 years is also greater for women than men: 21.9 versus 19.0 years. The established dummy variables were considered as independent variables, and a logistic regression model was established according to whether the patients were high-grade glioma or WHO IV grade glioma, which were set as dependent variables. https://doi.org/10.1016/s1470-2045(17)30194-8. 6 Jun 2018.

The cut-off of the model with the minimum AIC value was calculated by the same method described above. 1987;59(9):161725. According to whether the patient suffered from WHO IV glioma, the diagnostic age classification criteria were 014years old (pediatric group) and 1548years old (young group).
