Detailed Longitudinal Sampling Of Glioma Stem Cancer

Glioblastoma (pronounced like gleO blastoma) is an incurable brain cancer,Survival rate is usually measured in months.This became a word that was instantly defined, researched, dissected, feared, and tried to comprehend and understand by family,friends and acquaintances of Larry McKee (McKee)who was personally affected from this single word, it was quickly added to their vocabulary, because of the of the events that transpired on October 22, 2011 that forever changed lives “Glioblastomas are tumors that arise from the astrocytes- the star-shaped cells that make up the “glue-like,” or supportive tissue of the brain. These tumors are usually highly malignant (cancerous) because the cells reproduce quickly and they are supported by a large network of blood vessels.”(A.B.T A..) He was diagnosed with stage four.

The T category describes the original (primary) tumor. The tumor size is usually measured in centimeters (2 and 1/2 centimeters is about 1 inch) or millimeters (10 millimeters = 1 centimeter).

The concept of neurogenesis being confined to the embryonic stage became less obvious with the onset of discovery of neural stem cells maintained in two distinct regions of the mammalian adult brain namely dentate gyrus (DG) of the hippocampus and the sub ventricular zone (SVZ) of the forebrain lateral ventricles14,18,19. What makes these neural stem cells a more credible target for oncogenic transformation? The continual presence of undifferentiated, mitotically active, self renewable stem cells at the apex of the hierarchy bundled in discrete germinal niches in the mammalian brain throughout the lifespan of an organism allows them to accumulate mutations, thus rendering them vulnerable for neoplastic reprogramming. There has been increasing evidence that the genetic and epigenetic mechanisms that initiate and maintain the NSC developmental state are possibly deregulated in GB to emerge as Glioma initiating cells or Brain tumor stem cells20. The discovery of BTSC has high clinical significance in the neuro-oncology field, as evidenced by major diverse roles it plays in various aspects of tumor growth such as tumor initiation, maintenance, progression, angiogenesis and tumor recurrence owing to therapeutic resistance, some of which are described

Glioma is a tumor that occurs in the brain and different parts of the nervous system including the spinal cord that comes from glial cells. Glial cells are brain cells that turns into tumors. There are many types of gliomas and each type has different symptoms. Determining the type of glioma tumor depends on the location of the

Gliomas are the most common type of primary brain tumor, accounting for 10-20% of its total. (5,19–21). Histopathology pattern is the most important feature in glioma classification. (22) The 2007 WHO classification of tumors of the central nervous system divides gliomas into four main types, with increasing degree of malignancy (from I-IV). Low-grade gliomas are defined a grade I and grade II, in opposition to the “high-grade gliomas”, WHO grade III and IV. The so-called “diffuse low-grade gliomas” integrate 2007 WHO II class, and include diffuse astrocytomas, oligodendroglioma and oligoastrocytoma (mixed glioma) (19). There are some pertinent critics to this grading system, such as the great inter-variability among neuropathologist experts. More importantly, 2007 WHO grading doesn’t contemplate the continuum between grade II and III. In fact, many DLGG has an “intermediate” behavior, with some more aggressive microfoci lodged in the core of the neoplasm (19,23,24). Hence, the term diffuse low-grade glioma is preferred in this article.

A biopsy of the suspected cancer tissue is the only definitive diagnosis (Davis, 2016). There are several different ways a biopsy can be obtained such as through an endoscopy, needle biopsy, and surgical biopsy. Once the biopsy is obtained the tissue is examined under a microscope to determine whether the tumor is malignant or benign, type of cancer, and the tumor grade ("Module 6: Cancer," 2011). The tumor grade refers to how similar or different the cells resemble the normal tissue. If the tumor cells resemble the normal tissue it is referred to as well differentiated and tends to be slow growing and leads to good prognosis. However, if the tumor cells do not resemble or only slightly resemble the normal tissue it is referred to as poorly differentiated or undifferentiated. This is usually indicative of a fast growing and more aggressive cells that may ultimately lead to a poorer prognosis (“Module 6: Cancer,” 2011).

Exams and tests that are often used to make a brain cancer diagnosis may include CT scan, MRI scan, angiogram, skull x-ray, spinal tap, myelogram, and biopsy. When making a brain tumor diagnosis, the doctor performs a physical exam and asks questions about the patient's symptoms, personal and family medical history.

Their analysis showed out of 240 cases 93.67% cases were non neoplastic 8.62% cases were neoplastic lesions and malignant lesions were

Gliomas are broad category of brain tumors arising from glial cells. They are the most common primary malignant neoplasms of the central nervous system. They are classified into low-grade (WHO grades I and II) and high-grade (WHO grade III and IV) tumors. Almost 80% of gliomas are astrocytic tumors including Glioblastoma multiforme (GBM). Diagnosis of glioma includes a CT scan/MRI scan and biopsy. These tumors are highly resistant to current treatment modalities including surgery, radiation therapy, chemotherapy, corticosteroids, antiangiogenic therapy, and experimental approaches such as gene transfer, their prognosis is dismal.Malignant gliomas results from a multistep process which involves genetic alterations arised from innate and environmental

Tumor determination starts with an intensive physical exam and a complete therapeutic history. Research facility investigations of blood, pee, and stool can locate anomalies may demonstrate growth. The point when a tumor is suspected, imaging tests, for example, X-flashes, processed tomography, attractive thunder imaging, ultrasound, and strand optic endoscopy examinations help specialists figure out the growth's area and size. To affirm the finding of most tumors , a biopsy needs to be performed in which a tissue example is evacuated from the suspected tumor and considered under a magnifying lens to check for disease

In modern day medicine, the use of tissue biopsies is a well-established method for diagnosing cancer and other diseases. However, such procedures are often accompanied by technical limitations that can make obtaining the necessary amount of sample material from patients

Most primary tumors are triggered by out-of-control growth amid cells that surround and support neurons. In a trifling number of individuals, primary tumors might arise from particular genetic ailment (e.g., neurofibromatosis, tuberous sclerosis) or from exposure to radiation or cancer-causing compounds. The reason of most primary tumors remains unidentified. They are not transmissible and, at this time, not avoidable.

Gliomas are the most common primary malignant brain tumors in in humans with annual global incidence for approximately 5 cases per 100000 persons. The incidence of gliomas has moderately increased over the past two decades, which is mainly attributed to improved diagnostic imaging technique. Each year, more than 13000 deaths and 14000 new cases occur in the United States. In Taiwan, the incidence of malignant gliomas also presents similar ratio with approximately 6 cases per 100000 persons. Among the patients, malignant gliomas are 40% more frequently diagnosed in men than in women. Malignant gliomas can be classified into several categories according to its tumor cell type, location, and grade. Among the different types of gliomas, glioblastoma

Gliomas are the most common primary brain tumors in adults (1).Currently,Glioblastoma multiforme(GBM, also called grade IV astrocytoma)is the most malignant class of glioma, characterized by remarkable aggressiveness (2). GBM comprises accounts for 15% of all intracranial tumors in adults ages 40–75 (3). Despite multidisciplinary cooperation including surgical techniques, radiotherapy and chemotherapy, the prognosis of GBM remains gloomy as the median survival time for patients with GBM is less than 15 months after diagnosis (4, 5).

Tumors are one of the most feared diseases of our time. Many people upon hearing the word “tumor” immediately resonate to the conclusion of it being cancer, which is not necessarily true. Tumors fall into to two main types, benign and malignant. Although they are considerably different in tissue invasion, their nature that makes them distinct and symptoms, they are also quite similar in the way they recur in the same location, growth size and their health risks.
