Glioblastoma Essay

Once a person has been diagnosed with brain cancer, treatment should begin immediately. Treatment for brain tumors involves any combination of surgery, radiation, and chemotherapy. Some tumors require several different surgical procedures; some can be treated with radiation alone. Surgery is the best process to remove a brain tumor. Surgery attempts to remove most, if not all of the tumor. Once most of the tumor is removed, the rest of the tumor can be removed through a process called radiotherapy.

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.

Tumors can be classified into three types: 1) benign 2) pre malignant 3) malignant tumor. Benign tumors are those which are incapable of abrupt expanding and affecting the other healthy brain tissues. Premalignant tumor is a pre cancerous stage, if not treated properly it may lead to cancers. It is often considered as a disease. Malignant tumor grows rapidly with time an ultimately leads to death of patient. Malignant is a medical term describing a sever growth of a disease. The most common primary brain Tumors are gliomas, wherein 70% are in the group of malignant gliomas, glioblastoma multiform (GBM).The GBM is one of the highest malignant human

Glioma is a tumor that is a type of brain cancer. Glioma tumors are made up by cells called glial cells. Glial cells normally provide nutrition, oxygen, and structural support to the brain. Three types of glial cells can produce tumors. Gliomas are named after the type of glial cell that is involved in the tumor. A tumor is formed when the glial cells grow into an abnormal mass of tissue. Gliomas are one of the most common types of brain tumors that occur in adults.

CNS tumors represent the second most frequent tumor of childhood and the most common pediatric solid tumor; approximately 2,200 patients under the age of 20 are diagnosed each year with invasive CNS tumors, and CNS tumors are the number one cause of death from childhood cancer. [1] Therapeutic strategies generally involve surgery as a primary intervention, but complete resection is often not possible due to tumor location. In such cases, adjunct therapies, including chemotherapy and radiation therapy, may be required based on the tumor histology and presence of residual tumor. [2]

Mai is a 66-year-old female diagnosed with IV NSCLC (with multiple large brain metastases) EGFR exon 19 deletion (C34.90). Mai experienced headaches, weight loss, nausea, and vomiting. A very recent CT scan revealed multiple brain metastases, which are large, and throughout the cerebral hemisphere including both of the cerebellums. Mai is being treated with radiation, decradron and high-dose steroids, but still experienced disease progression. The denial states that Mai must try to fail Tarceva, Iressa and Gilotrif, however due to the highly acute, tumor burden brain metastases, with Tagrisso as a front-lien treatment it will actively fight against exon 19 deletion and more importantly, good CNS activity. Given these results of Tagrisso,

DIPG (Diffuse Intrinsic Pontine Glioma) is a disease which strikes at the heart of childhood. At the base of the brain, just above the spinal cord is the brainstem. The tumor affects the pons area of the brainstem, supplying the nervous system function unattainable. ‘“There’s not a single drug approved”’ (Mukhopadhyay). Due to the location of the tumor, it cannot be surgically removed. Unfortunately, the only option available is Radiation that is considered temporary, with no benefits. “Chemotherapy is frequently ineffective, since anti-cancer drugs cannot cross the blood-brain barrier and reach the tumor” (Zhiping 2). In the end, leaves the patient and parents hopeless for fighting this

Glioblastoma Multiforme is an extremely aggressive brain tumor that can drastically alter how the body moves, a person’s memory, vision, emotion, thought, etc (GBM Guide). Having something in your brain that has the potential to drastically

Glioblastoma(GB) is the most common primary malignant solid brain tumor in adults1. Known for its aggressive characteristics and poor prognosis, the median survival rates of GB patients remain less than 18 months2,3. Tumor relapse owing to chemotherapeutic resistance is almost universal and GB is no exception, thus reflecting in high mortality and morbidity rates4. The WHO 2016 classification of brain tumors identifies GB tumors based on histology, molecular and genetic characterization into defined transcription profiles such as classical, neural, pro-neural and mesenchymal types5. Additionally, the commonly occurring genetic aberrations of primary GB are amplifications/mutations of EGFR, PDGFRA, PTEN, and of secondary GB are IDH1, MDM2

These tests include CT/MRI scans (using x-rays, magnetic fields, and radio frequencies to get a detailed image of your organs and body parts), MIBG scans (scans that try to locate metaiodobenzylguanidine or MIBG, which is a substance that builds up in tumors like neuroblastoma ), biopsy (sampling of body tissues in a lab), urine testing, and a bone marrow aspiration and biopsy (removing bone marrow and sending the bone marrow to a lab to see if cancer is present ). If these tests reveal that a patient has neuroblastoma, then doctors will try many treatments to get rid of the tumor. These treatments include surgery (directly removing the tumor), chemotherapy (anti-cancer drugs), radiation therapy (high energy rays used to kill cancer cells), retinoid therapy (chemicals that try to convert cancer cells to normal cells), immunotherapy (medicines that help your immune system recognize and destroy cancer cells), and stem cell transplant or bone marrow transplant (replacing worn out bone marrow cells that produce blood cells that were destroyed during radiation therapy and chemotherapy) . Scientists today think that neuroblastoma is not caused by any environmental factors, but they are still not sure. While scientists do not know if environmental factors are present, they do know that susceptibility to neuroblastoma can be inherited through the

Immunotherapy is the most promising new cancer treatment since the development of chemotherapies in the 1940s and thus has the potential to produce a plethora of effective treatments for future patients fighting the disease for decades to come. Essentially, these drugs work by targeting the host immune system, instead of the tumor, in order to attack cancer cells harder and smarter than through previous treatments (Kohrt et. al., 2016). The immune system recognizes the tumor cells as foreign, triggers an immune response, and then promotes tumor cell death or growth inhibition (Berman and Simone, 2016). When considering all of the involved immune cells, cytokines, and other immune factors that play a role in the function of the immune system, it is clear that there is a potential to develop many novel anti-tumor strategies for the future (Thara & Barzi, 2015).

As the world continues to suffer from these devastating diseases, researchers continue to find alternative therapeutic ways of addressing cancer treatment. It is on this premise that various immunotherapeutic alternatives have emerged and currently garnering the greatest level of attention and already raising hope throughout the world in addressing the treatment of NSCLC. However, this can no longer be viewed as a discovery but a wave in the medicine world that began in the 20th century. Various researchers have found the importance of the role of immune systems in fighting the growth of tumor caused by cancer cells. A study by Huncharek (2000) stated that specific immune boosters are capable of eliminating preclinical cancers. In contrast, Jermal et al. (2011) found that immunotherapy is an effective approach for the treatment of tumors that have already turned into solid. Similarly, the researchers highlighted that immunotherapy can be an effective approach to the treatment of melanoma as well as renal cell cancers (Lasalvia-Prisco, 2008). However, Jemal et al. (2011) noted that immunotherapy cannot achieve much in cancer treatment due to limitation brought about by the emission of immunosuppressive cytokines and subsequent loss of antigen expressions. Recent development in research studies on the immunotherapy approach to cancer treatment continues to elicit mixed reactions among researchers of medicinal ecology (Jadad et al., 1996). However, recent development in

This letter is written in support of Dr. Rodney Macedo Gonzales application for a CRI Irvington Postdoctoral Fellowship studying the role of chemokine inhibition in the melanoma treatment under the mentorship of Dr. Ran Reshef. During the last few years, I have worked closely and collaborated on several projects with Dr. Reshef. These efforts have resulted in multiple publications using chemokine inhibition for reducing immune-related effects in GvHD and other diseases. Now with Rodney as part of his team, they are planning to use this strategy for improving the effect of PD-1/CTLA-4 blocking in melanoma, as well as reducing the immune-related toxicity observed in these patients after treatment.

Common malignant brain cancers increase significantly according to statistical data collected by the National Cancer Institute. In 1984, the annual incidence rates of primary brain tumor and primary brain lymphoma also increased notably, the rate of lymphoma almost tripling,

Another major breakthrough that occurred in the early 1970’s was the discovery of the first promising chemotherapy for glioma. A glioma is a malignant tumor that begins in the glial cells which surround the nervous system. Gliomas can be found in the brain and spinal cord. Researchers studied a chemotherapy drug called carmustine (BCNU) and
