‘High-grade Glioma (HGG) - Epidemiology Forecast–2030’ report delivers an in-depth understanding of the disease, historical and forecasted High-grade Glioma (HGG) epidemiology in the United States, EU5 (Germany, Spain, Italy, France, and United Kingdom) and Japan.

High-grade Glioma (HGG) Understanding
Highly malignant or high-grade gliomas (HGG) are tumors of the central nervous system (CNS), wherein high-grade means that the glioma is growing rapidly. They are solid tumors arising from transformed cells of the brain and/or the spinal cord. Since they directly originate from the CNS, they are also called primary CNS tumors, thereby differentiating them from malignant tumors of other organs that have spread (metastasized) to the CNS. HGG can occur in different parts of the central nervous system, and they can affect children of any age. The tumors most often originate in the supratentorial region of the brain and the brain stem; HGG originating from the supratentorial region are often called supratentorial HGG.
A glioma is a name for tumors of the glial cells, which are the supporting cells of the nervous system. Gliomas are classified based on the type of glial cells involved in the tumor as well as tumor’s genetic features. The World Health Organization (WHO) classification of CNS tumors is the most widely accepted system for classifying CNS tumors and was based on the histological characteristics of the tumor. As per the WHO classification system, grade III tumours (i.e. anaplastic astrocytoma, anaplastic oligoastrocytoma and anaplastic oligodendroglioma), grade IV tumours (i.e. Glioblastoma) and diffuse midline gliomas (DMG), H3K27M-mutant are considered to be high-grade gliomas (HGG).
HGGs account for approximately 15–20 % of CNS tumors in children and adolescents. They appear in all age groups, yet, children aged younger than three years are rarely affected. Each year, about 60–80 children and adolescents younger than 15 years are newly diagnosed with an HGG, which corresponds to an incidence rate of 5–10 new diagnoses/1, 000, 000 children/year. HGGs affect both boys and girls almost equally, and its symptoms vary depending on which area of the brain is affected.
The initial diagnostic procedures for a young patient presenting with a suspected CNS tumor at a childhood cancer center include another assessment of the patient’s history, a thorough physical/neurological exam and imaging diagnostic, such as magnetic resonance imaging (MRI). However, diagnostic procedures required for a definite and complete diagnosis of HGG involves:
• Imaging studies require a whole-brain scan, which can be done using MRI or CT. Both tests provide a very detailed image of the brain. Usually, a contrast dye is also given through a vein for the CT or MRI to visualize the brain better. However, a CT or MRI cannot determine for sure if a mass is a brain tumor.
• The only way to determine the type of tumor with certainty is for a neurosurgeon to remove a piece of the tumor during surgery (resection), which can then be studied under a microscope.
• A biopsy may be done without a larger surgery; this approach is preferred if the tumor is located within a critical area of the brain or if the patient is too sick for surgery. In these circumstances, a procedure called a stereotactic needle biopsy is used to take a sample of the tumor by inserting a needle through the skull into the brain itself.
Treatment for HGG usually includes a combination of surgery, chemotherapy, radiation, or stereotactic radiosurgery. Surgery is usually one of the most important aspects of treatment, although rarely used alone. Since HGGs develop very rapidly, they are often difficult to remove in their entirety. Therefore, surgery is performed to achieve a maximum safe resection - removing as much of the tumor as possible while preserving the patient’s brain function and sparing healthy tissues. Residual cancer cells can be targeted with additional treatments, such as chemotherapy or radiation therapy, after surgery. Radiation therapy and chemotherapy usually follow surgery once the diagnosis or name of the tumor is determined. These treatments are called adjuvant treatments. Because this multispeciality approach can cause several side effects, steroids are often provided as another essential part of HGG treatment, used to help alleviate the side effects of other therapies.

<>High-grade Glioma (HGG) Epidemiology Perspective
The disease epidemiology covered in the report provides historical as well as forecasted epidemiology segmented by Total Incident Population of High-grade Glioma (HGG), Total Incident Population of Diffuse Midline Glioma (DMG), Total Incident Population of Diffuse Midline Glioma With H3K27 Mutation and Gender-specific Incidence of High-grade Glioma (HGG) in the 7 MM market covering the United States, EU5 countries (Germany, France, Italy, Spain, and United Kingdom) and Japan from 2017–2030.

<>High-grade Glioma (HGG) Detailed Epidemiology Segmentation
• The total incident population of High-grade Glioma in the 7 major markets was found to be 32,444 in 2017. In case of High-grade Glioma patients in the United States, the incident cases were estimated to be 16,295 in 2017.
• There are three main types of High-grade Gliomas that are considered in this report: Anaplastic Astrocytoma (WHO Grade III tumor), Glioblastoma (WHO Grade IV tumor) and Diffuse Midline Glioma (WHO Grade IV tumor), where the majority of cases were found to be of glioblastomas that develop rapidly de novo, without clinical or histological evidence of a less malignant precursor lesion.
• Incidence of Diffuse Midline Glioma with H3K27 Mutation has been considered in this report as well. The highest incidence of H3K27 mutants were found in pediatric population which was estimated to be 303 in 2017 in the United States. However, the incident population of H3K27 mutants in adult population was found to be 204 in 2017 in the United States.
• Japan accounted for 2,519 incident cases of High-grade Glioma in 2017, which is expected to increase in the forecast period 2020–2030.

• Total Diagnosed Prevalent Population of High-grade Glioma (HGG)
• The report contains Gender-specific prevalence of HGG in the 7MM, wherein males are found to suffer more as compared to females.
• Report also covers Incident Population of Diffuse Midline Glioma, including both adult and pediatric population of HGG.
