The giant-cell glioblastoma is a histological variant of glioblastoma, presenting a prevalence of bizarre, multinucleated (more than 20 nuclei) giant (up to 400 μm diameter) cells. It occasionally shows an abundant stromal reticulin network and presents a high frequency of TP53 gene mutations .
The International Classification of Diseases for Oncology (ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries. It is currently in its third revision (ICD-O-3). ICD-10 includes a list of ...

The concept of grading of the tumors of the central nervous system, agreeing for such the regulation of the "progressiveness" of these neoplasias (from benign and localized tumors to malignant and infiltrating tumors), dates back to 1926 and was introduced by P. Bailey and H. Cushing, [1] in the elaboration of what turned out the first systematic classification of gliomas.
Glioblastoma (GBM) is the most common and aggressive malignant brain tumor, accounting for about 15% of all primary malignant brain tumors. Dr. Hersh: Glioblastoma is the most common and ...
Glioblastoma pre (left) and post (right) resection. Surgery is the first stage of treatment of glioblastoma. An average GBM tumor contains 10 11 cells, which is on average reduced to 10 9 cells after surgery (a reduction of 99%). Benefits of surgery include resection for a pathological diagnosis, alleviation of symptoms related to mass effect ...
However, modern sequencing techniques have revealed that the molecular alterations driving the cancer are entirely distinct to GBM, leading to changes in the World Health Organization classification system. [4] [5] [2] They are further distinguished from GBM by their radiological presentations, including no or faint contrast enhancement. [3]
