However, interactions of some factors such as tumor site, age, and treatment strategy can affect one's prognosis. [2] For instance, when younger children below the age of three develop tumors originating in places other than the pineal gland are treated with chemotherapy , they present better outcomes than those with pineal tumors and treated ...
Primitive neuroectodermal tumor is a malignant (cancerous) neural crest tumor. [1] It is a rare tumor , usually occurring in children and young adults under 25 years of age. The overall 5 year survival rate is about 53%.
A phase III study of sunitinib treatment in well differentiated pNET that had worsened within the past 12 months (either advanced or metastatic disease) showed that sunitinib treatment improved progression-free survival (11.4 months vs. 5.5 months), overall survival, and the objective response rate (9.3% vs. 0.0%) when compared with placebo.

The second part is stabilizing the tumor progression. Gastrinomas have a rate of 60–90% that will become malignant. [15] Patients who do not seek medical treatment such anti-ulcer medication have high rate of recurrence and death secondary to ulcer disease. The prognosis of gastrinoma depends on the level of metastases of the tumor.
NETs include certain tumors of the gastrointestinal tract and of the pancreatic islet cells, [1] certain thymus and lung tumors, and medullary carcinoma of the parafollicular cells of the thyroid. [1] Tumors with similar cellular characteristics in the pituitary, parathyroid, and adrenomedullary glands are sometimes included [9] or excluded. [1]
Tumors that originate in the cerebellum or the surrounding region below the tentorium are, therefore, called infratentorial. Historically, medulloblastomas have been classified as a primitive neuroectodermal tumor (PNET), but it is now known that medulloblastoma is distinct from supratentorial PNETs and they are no longer considered similar ...
Malignant ectomesenchymoma (MEM) is a rare tumor of soft tissues or the CNS, which is composed of both neuroectodermal elements [represented by ganglion cells and/or well-differentiated or poorly differentiated neuroblastic cells such as ganglioneuroma, ganglioneuroblastoma, neuroblastoma, peripheral primitive neuroectodermal tumors – PNET ...
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] Common symptoms of CNS tumors include vomiting, headache, changes in vision, nausea, and seizures. [3]
