A central nervous system tumor (CNS tumor) is an abnormal growth of cells from the tissues of the brain or spinal cord. [1] CNS tumor is a generic term encompassing over 120 distinct tumor types. [ 2 ]
The 5th WHO classification delineates distinct types of tumors, some of them being further divided into subtypes, rendering the former terms entity and variant obsolete. When molecular diagnostics are not complete enough to allow precise classification, diagnosis should be designated by appending not otherwise specified (NOS).
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.
A vestibular schwannoma (VS) is only one type of tumor. The Central Brain Tumor Registry of the United States (CBTRUS) is the primary national database of malignant and benign tumors of the brain, "other central nervous system (CNS), tumors of the pituitary and pineal glands, olfactory tumors of the nasal cavity, and brain lymphoma and leukemia."
Tumor volumes were defined either by expert radiation oncologists or using semiautomatic segmentation methods. [ 22 ] [ 23 ] Their results identified a subset of radiomic features that may be useful for predicting patient survival and describing intratumoural heterogeneity.
